Description

 Process for the treatment of waste and waste treatment plant

description

The invention relates to a process for the treatment of waste with organic components according to the preamble of claim 1 and a waste treatment plant for carrying out the process.

With the introduction of the separate collection of organic household waste in Europe, the mechanical biological treatment (MBT) of municipal waste has become increasingly important. The degradation of the biogenic mass is microbial, whereby a distinction can be made between aerobic and anaerobic microorganisms. The aerobic conversion ultimately leads to the end products carbon dioxide and water and is referred to as rotting. The anaerobic conversion is typical for fermentation, as end products are produced, inter alia, methane, ammonia and hydrogen sulfide.

Known methods provide various time-consuming waste treatment steps, depending on the nature of the waste mixtures. Furthermore, expensive waste treatment plants are required to carry out the known processes. In particular, the present invention relates to non-disposable waste according to EU regulations.

The object of the present invention is to provide a process for the treatment of waste with organic components, which allows a rapid and cost-effective treatment of the waste, and a waste treatment plant for carrying out this process.

This object is achieved by a method having the features of claim 1 and by a waste treatment plant having the features of claim 4.

In a method of treating organic matter waste according to the invention, the waste is fed to a pulper for dissolving organic matter. The dissolved organic components are discharged in a suspension from the pulper, which is subjected to the separation of solids and fibers of a substance separation. The thereby arising freed from solids organically highly loaded circulating water is fed to a fermentation stage for the production of biogas fermentation.

For uniform supply of circulating water to the fermentation stage, the circulating water can be stored in a buffer.

In a variant of the method, the buffer can be operated as a hydrolysis reactor in which the circulating water is subjected to hydrolysis before it enters the fermentation stage.

A waste treatment plant according to the invention provides a pulper, a substance separation and a fermentation stage.

Preferably, a temporary storage is provided for storing the recovered in the separation of substances highly contaminated with organics circulating water, which can be operated advantageously as a hydrolysis reactor.

In the case where at least a part of the waste is delivered in bags, a bag opener may be provided which is preferably made with a loading and stuffing screw and one of these downstream snail.

In a further embodiment of the invention, the mechanical treatment of the delivered waste via a screening and classification plant, which can replace conventional, large-volume drum screens. The screening and classifying plant according to the invention has a first, carried out with a perforated screen screw conveyor or conveyor spiral. The sieve passage is transported via a downstream screw conveyor / spiral to the next processing stage. The screen overflow is further conveyed by the former spiral and preferably classified by means of a ballistic sifter.

In another embodiment, a pulper is associated with an additional device, is subtracted from the floating matter, in particular a plastic-containing fraction of a dome of the pulper. In a particularly preferred solution, the water level in the dome may be increased to remove the plastic-containing waste fraction via an overflow and continue to promote and drain by means of a suitable conveyor.

According to an advantageous embodiment of the invention, the pulper can be preceded by a squeezing device in order to leach the waste to be treated, i. in a mushy state, so that the suspension in the subsequent pulper is much faster and more uniform.

Other advantageous embodiments are the subject of further subclaims.

In the following preferred embodiments of the invention will be explained in more detail with reference to schematic representations. Show it

It is expressly mentioned that in the following description of the figures to Figures 1, 2 and 3 only some material or material flows and equipment parts are described. That is, not all the material flows shown in FIGS. 1, 2 and 3 are explained. In this context, reference is made to the applicant's PCT application PCT / EP2005 / 005993, which expressly forms part of this application. To avoid irritation, the same reference numerals are used in this application and in the PCT application for the same system parts, material flows, etc. - A -

1 shows a first embodiment of a waste treatment plant for the treatment of organic waste is shown. The following explanation of Figure 1 is greatly simplified and only shows significant material flows. For further explanations, reference is expressly made to the description of the figures relating to FIGS. 1 to 11, in particular FIG. 9, of the PCT application.

At the beginning of the process, the waste 60 to be treated is fed to a screening plant 62. The resulting screen 78 is then passed into a pulper 1. The resulting in pulper 1 Stör- / heavy substances 18 are withdrawn from the pulper 1 via the outlet lock 16 and a washing device 80 supplied in which they are cleaned of persistent organic constituents in a cleaning zone 106 by means of supplied operating water 82.

The digested suspension 20 withdrawn from the pulper 1 via an outlet lock 16 is fed together with the polluted process water 96 from the washing device 80 to a pulp separator 98. In this pulp separator 98, fiber and floating matter 100 are separated from organically-containing water 102. The fibrous materials 100 are cleaned in a solids screen and washer 104 by addition of process water 82.

The cleaned and withdrawn via the solids outlet 110 of the washer 104 solid and fibrous materials 112 are then dewatered in a dewatering press 114 and fed the dewatered solids 116 a thermal utilization or a Nachrotte for later landfilling.

The dissolved in the dewatering press 114 containing dissolved organic water 118 is then blended with the flowing out of the washing device 104 with organic laden wash water 120. This stream contains a proportion of fine sand, which is separated in a sand scrubber 122. The material stream and the organics-containing water 102 is fed from the pulp 98. In the sand scrubber, the fine sand portion 124 is cleaned of adhering organic matter. The pre-cleaned fine sand 124 is then fed to a fine sand washing device 128. The cleaned fine sand 130 can then be used for material recycling in civil engineering and road construction. The highly polluted circulation water 132 present after the sand washing is then intermediately stored in a buffer store 134 and supplied to a fermenter 138 by means of a pump 136.

Depending on the process, the organic constituent of the water supplied to the fermenter 138 is converted into biogas (methane gas) 144 by methanation.

The present after the fermentation stage, discharged from organic wastewater 146 is then mixed with the possibly existing circulating water 132 to the so-called mixed water 158 and brought in the heat exchanger 140 to process temperature. Excess water 147 that is not needed in the circuit is fed to a wastewater treatment plant 148 and the purified wastewater 150 is discharged and discharged into the sewage system. A partial stream of the purified wastewater 150 is fed as process water 82 to the washing devices 80, 104, 128 and to the sand scrubber 122.

The mixed water 158 can be subjected at least as a partial stream to a wet oxidation or wet oxidation 164, after which an oxidized and de-nitrogened substance mixture 23 is discharged, which is freed from solids in a separation plant 168. The resulting almost solids-free wastewater 170 is then fed to the wastewater treatment plant 148. The resulting raw compost 212 is disposed of.

Figure 2 shows a second embodiment of a

Waste treatment plant. The following explanation of Figure 2 is greatly simplified and only shows significant material flows. For further explanations, reference is expressly made to the figure descriptions to the figures 12 to 24, in particular Figure 19, the aforementioned PCT application.

At the beginning of the waste treatment, the waste 60 to be processed is first fed to a screening plant 62. The resulting rich in organic sieve 78 is fed to the pulper 1 and 1.1 respectively.

The impurities / heavy substances 18 contained in the pulper 1, 1.1 are withdrawn via the outlet lock 16 from the pulper 6 and a A washing device 80 is supplied in which the interfering / heavy substances 18 adhering organic constituents are cleaned in a cleaning zone 106 by means of supplied operating water 82. The thus cleaned interfering / heavy substances 84 can then be fed to a ferrous metal separator 86 and a non-ferrous metal separator 88 so that the material flow of the interfering / heavy substances 84 is divided into an iron-containing fraction 90 and a non-ferrous metal fraction 92 and other substances 94.

The digested suspension 20 withdrawn via the outlet lock 16 from the pulper 1, 1.1 is fed to a pulp separation unit 300 for separating the liquid 132, which is heavily loaded with organic matter, from the essentially organically-free solids 116 in the suspension 21. As a by-product of this substance separation 300 purified fine sand 130 is obtained, which can be removed from the process.

The dehydrated solids 116 are, after passing through a drying process 311, supplied to a compacting plant 312 for the production of a fuel for thermal / material utilization in a gasification or incineration plant 317.

The organically highly stressed liquid 132 is stored in a buffer 134 and fed to a fermenter 138 as needed for biogas production.

In the fermenter 138 132 biogas 144 is recovered under the influence of methane bacteria from the organically highly polluted circulating water. Entowered waste water 146 accumulates here, which can be supplied to a wet oxidation 164, 164.1 as de-energized digester water 159.

The oxidized substance mixture 23 obtained during the wet oxidation 164, 164.1 is fed to a separation plant 168 for the production of solids-free wastewater 170, which is used for a wastewater treatment plant 148 and / or as a dilution water 4 for the pulper 1, 1.1. The solids separated in the separation unit 148 are used as raw compost 212. The purified wastewater 150 of the wastewater treatment plant 148 is fed to the sewerage and / or as process water 82 of the washing device 80 and / or the mass separation plant 300. FIG. 3 shows a third exemplary embodiment of a waste treatment plant according to the invention. In order to avoid repetition, reference is made to the waste treatment plants according to FIGS. 1 and 2 and only a few differences between the waste treatment plants according to FIGS. 1 and 2 and the waste treatment plant according to FIG. 3 are explained.

The essential difference to the above-described waste treatment plants according to Figures 1 and 2 is that the buffer 134 for storing the organically highly loaded circulating water 132 can be operated after the separation 98, as Hydrolsyseaktor 162, so that the circulating water 132 in the buffer 134 of a Hydrolysis can be subjected and then fed to the fermentation stage 138 as recycled circulating water. The hydrolysis 162 is preferably uncontrolled. A possible construction and possible operation of the hydrolysis reactor embodied as a buffer 134 is shown in FIGS. 15, 16, 17 and 20 of the abovementioned PCT application, to which reference is expressly made.

Another difference to the above-described waste treatment plants according to Figures 1 and 2 is that instead of a pulper two pulpers 1, 1.1 are connected in series one behind the other. Here, reference is expressly made to the figure descriptions to the figures 12, 13 and 14 of the aforementioned PCT application.

Another difference from the above-described waste treatment plants according to FIGS. 1 and 2 is that, by way of example, three reactors for carrying out the wet rotations 164, 164.1 after fermentation 138 are shown. Here, reference is expressly made to the figure descriptions to Figures 15, 16, 18 and 21 of the aforementioned PCT application.

In the following, a preferred embodiment of the invention will be explained with reference to the process scheme according to FIG. With regard to the basic structure, this method corresponds to that of FIG. 3, so that only the essential method steps are explained here. The delivered waste 60 is cached in a flat bunker and distributed by means of, for example, a wheel loader 321 or a Greiferbaggers 322 and transported to the next stage of the process. This will be great Interfering 323 separated and divided by hand sorting into different fractions, which are then received in appropriate containers, such as metal, glass, PVC, textiles, shoes, wood, plastic / PET, etc.

The bags contained in the waste are opened by a bag opener 330 and crushed. This bag opener 330 is explained in more detail below with reference to FIGS 5 to 7. Here, the shredded / torn waste components are further divided by means of a ballistic air sifter 68, with heavy / impurities 70 of the aforementioned hand sorting 324 and the corresponding assignment are supplied. The remaining residual waste 71 freed of heavy and / or impurities 70 is then fed to a sieving and classifying plant 350, which will be explained below with reference to FIGS. 8 to 10. About this designed as a spiral screen sieve and classifier 350, the waste fraction is further divided, which is assigned by a further ballistic classification heavy material of the aforementioned hand sorting 324. The sieve pass 2 is fed to a pulper 1.1. The screen overflow, for example, larger plastic parts, cardboard, etc., is fed to a shredder 503 and entered in shredded form 504 in a dryer 311.

In the pulper 1 of the screen passage 2 is suspended and dissolved, with interfering and heavy materials 18 are withdrawn through the outlet lock 14, 16. The pulper 1.1 is associated with an additional device 400 for floating material, in particular plastic separation. This additional device acting on the flotation principle is explained below with reference to FIGS. 11 to 13.

The withdrawn floating substances are dewatered by means of the additional device 400 and conveyed via the resulting dewatering pressure 407 to the abovementioned shredder 503 and introduced from there into the dryer 311. The dry material is removed from the dryer 311 and separated by suitable methods, for example by electronic detection into different fractions (paper, cardboard, mixed plastic, PVC, PET, inert glass 94, ferrous metals 90 and non-ferrous metals 91). This electronic separation plant for the dried recyclables is designated in Figure 4 by the reference numeral 311.1. The suspension 20 / 20.1 (freed from plastics) produced in pulper 1.1 contains a high proportion of organic materials. The contaminants 18 drawn off via the lock 14, 16 are divided and stored by suitable separation methods into iron and non-ferrous metals and other substances 90, 92, 94. The organic constituents 453-containing suspension 20.1 is then fed to a squeezing device 450 in which the organic constituents are lost, ie converted into a pulpy state. This squeezing device 450 will be explained with reference to FIGS. 14 to 16.

This crushing and forcing can be accelerated by supplying purified waste water 150. The mushy mass 458 (Mus) is then fed to a second pulper 1.1 and further dissolved there. The discharged via a lock 14, 16 Stör- / heavy materials are divided, for example, in the first pulper 1.1 associated separation plant in the fractions 90, 94, 92. The suspension 20 present after the second pulper 1.1 is then fed to a pulping plant 300, as described in the aforementioned PCT patent application. With regard to the details of this substance separation plant 300, reference may therefore be made to FIG. 22 of the PCT patent application. The separation plant 300 contains a pulp separator and a sand scrubber. Furthermore, solids 116 produced in the separation plant are dehydrated and added to the material stream present after shredder 503. The cleaned fine sand 130 is stripped off and the finest fibrous materials are separated off from the remaining, organically highly loaded water by means of a fine sieve system 98.1. The circulating water freed from the separation of sand, fibrous materials, etc., is then passed to a buffer store (buffer) 134, which according to the embodiments described above can also be operated as a hydrolysis reactor 162. In the intermediate memory 134 recorded organically highly charged water 132 can then be withdrawn via a pump and the biogas plant 138 are supplied, wherein the resulting biogas 144 is energetically utilized. So it can be used for example as a heating medium for the process described.

The discharged wastewater 164 obtained in the biogas plant 138 can then be supplied to the first pulper 1.1 after being heated in a heat exchanger 140 (heated by the heating medium 142). In principle, the discharged wastewater can also be fed to a reactor 174 for wet oxidation (wet rotting) 164. In this reactor 174 will not be anaerobic decomposable organics respire and the nitrogen expelled as ammonia. In the wet grate 164, the circulating water 132 is thus de-embroidered and prevents concentration of ammonium, which disturbs the biology in the fermenter 138 and inhibits gas production and degradation. Further details of wet oxidation can be found in the said PCT application.

The recirculating water freed from ammonium may be supplied to a sewage treatment plant 148 with microfiltration and reverse osmosis. This wastewater treatment plant 148 may also be supplied with a portion of the loaded wastewater received in the intermediate storage tank 134, this waste water stream being digested by hydrolyzing in the intermediate storage / hydrolysis reactor 162. The present after the wastewater treatment (microfiltration, reverse osmosis, etc.) operating water 150 can then be recycled as circulating water fed to the process, for example, the heavy materials 18 after the first pulper 1.1, the squeezing device 450 or the separation system 300 can be supplied. Any accumulating excess water 147 is withdrawn and introduced, for example, in the sewer. The vapor condensate 311.2 obtained during the drying in the dryer 311 is fed to the wastewater treatment plant 148, preferably between the microfiltration and the reverse osmosis.

As further figure 4 is removed, which accumulated in the heavy / impurity separation after the pulper 1.1, highly charged organic wastewater can be stored together with the wastewater after sanding wastewater in the buffer 134 and then processed in the manner described above.

After the wet oxidation 164 or elsewhere obtained solids can still be fed to a dehydrator 168, wherein the dewatered solids 116 are dried in the dryer 311. The accumulating press juice 210 can be supplied to the separation plant 300, for example. As further indicated in FIG. 4, the waste treatment plant is designed with an exhaust air treatment, which may include, for example, an acidic air scrubber 172 and a further purification stage 240.

The above-described plant concept can be used practically for processing any waste. In principle, incontinence products can also be processed or at least the invention Methods are combined with methods for processing incontinence products. It can also be processed in a recycling bin recyclables such as paper, cardboard, PET, glass. Such recyclables are used for example in France, England, USA, Canada, Italy, etc. The PVC separated with the waste treatment process can be recycled in a central recycling plant. The mixed plastics sorted out according to the above-described steps can, for example, be converted into diesel fuel, inert materials, incl. Glass, for example, to split. Thus, with the exception of textiles, shoes, etc., which make up about 9% of the total input, the installation can be essentially run without output.

The Applicant reserves the right to direct his own independent claims to the new mechanical processing techniques according to the Bag Opener 330, the Screening and Classification System 350, the Additional Device 400 for the Pulper 1.1 and the Crimping Device 450 and to further pursue these in divisional applications.

FIGS. 5 to 7 show a novel bag opener 330 which is charged via the gripper excavator 322 with coarsely pre-sorted residual waste 326 via the feed hopper 331.

Depending on the throughput of the system, the diameters d and the lengths L1 and L2 vary.

For example, for a throughput of 10 to 15 Mg / h (equivalent to approximately 20 to 30 m ³ / h), the diameter d would be approximately 700 mm and the lengths L1 and L2 approximately 6.0 m each.

The loading and screwing screw 332 has a speed control, so that during normal operation, the screw 332 rotates by about 30 to 40% less fast than the snail 333 which is also equipped with a speed control.

The sacks and containers with waste components 334 already torn by the loading and stuffing screw 332 are pressed in by the larger pitch S1 (corresponds to approx. D / 2 into the snail 333 with the smaller pitch S2 corresponds to approx. D / 3) and torn open at the same time , Smaller packing and paper sacks with a content of 1 to 3 liters can partially slip in unscathed. Long parts such. As skis and wood with a diameter up to 100 mm are broken. For larger parts, especially steel, such as crankshafts, etc., the machine locks and reverses two times before an alarm raises. Thereafter, the lid 336 must be opened and the defect removed by hand or with a gripping or cutting tool provided (eg a hydraulic scissors, which is also used in firefighting operations).

Which is shown with the downstream Ballistiksichter 68 to herein as scrap treadmill 68.1 are represented by the variable speed of the belt 68.1 with about 1, 5 to 3,5 m ¹ per second, the heavy particles 70 more shot than the light portions 71 which additionally through the descending air stream 68.2 are directed from the fan 62.3 down 71.1 and passed as a "light" waste fraction 71 in the conveyor 68.4. With the conveyor 68.3 the heavy materials 70 are promoted for hand sorting 324.

FIGS. 8 to 10 show a novel screening and classifying system 350 which replaces the large wear-resistant drum screen systems.

The basic function consists of two superimposed spirals (screws) 351 and 352 wherein the overhead spiral 351 has a perforated screen 353, through which on the shear forces of the spiral 351 small parts with high organic content 354 and small bag 355 opens and their content according to the selected sieve size 353 of the underlying spiral feeds.

The large-area plastic film parts 356 and hard parts 357, which do not fall through the screens 353, are discharged into the discharge chute 359. The falling material 358, which consists of light and heavy materials, is classified by an air classifier 360. By the air flow 361, the lightweight parts such as paper, cardboard and plastic parts 362 are blown into the shaft 363.

The underlying spiral 352 promotes the so-called organically rich Siebunterlauf 354 in the pulper I 1.1.

The upper screen is provided with a hinged cover device 364 for the maintenance and possibly removal of contaminants. The below Conveyor 352 may be accessed by a fold-down device 365 (as shown here) or by other mechanical devices for maintenance.

Depending on the throughput and separation efficiency, the spiral diameter d is selected. The length L1 corresponds to, depending on the desired residence and cycle time between 15 to 20 times the diameter d. The screenless end piece L2 is about 4 times the diameter d.

The screen graduation according to FIG. 10 depends on the water content, organic proportion and the areal proportion of plastic in the residual waste (). The division shown here corresponds to a waste collection in plastic bags with a dry matter content of 50%.

Was chosen for:

- a = 90 mm

- b = 40 mm

- c = 60 mm

Depending on the composition of the waste, these dimensions (a to c) may change by approximately ± 30%.

FIGS. 11 to 13 show the pulper 1.1 with an additional device 400 in the draw-off dome 288.

Due to the lowered water level 286.1 of the pulper 1.1, the floating plastic components through the flotation 156 / 18a in the dome 288 of the pulp 6. With open slide 401a, the suspension flows as freed from impurities 18 mixture 20 to the plant 450. To the plastic fraction 402 specifically to detect and subtract, this is done by the device 400. The flotation 36/150 is throttled and the agitator 272 turned off and the slide 401b closed, thereby the liquid level of 286.1 by the set height h2 is raised to the overflow pool 286. The substrate water 20 then passes together with the plastics 402 into the dewatering spiral 403, under which a sieving and dewatering basket 404 is attached, which runs off the entrained water with a gap width of 0.2 to 1.5 mm. With the spiral 405, the plastics are pressed to the somewhat slower running Hochförderspirale 406. The pressure 407 additionally dehydrates the plastics. The suspension 20, which has been largely freed from the floating plastics 402, is led via the overflow 408 to the device 450.

Depending on the waste composition and its plastic content, this process (which takes about 10 minutes) is carried out at least once per hour.

FIGS. 14 to 16 show a squeezing device 450 for the organic constituents of the suspension 20 freed of plastics 402 and impurities / minerals 18.

First, in a drum screen 451 at a sieve gap between 0.5 to 5.0mmm, the suspension 20 is separated into aqueous, dissolved organics 452 and solid or fibrous matter 453 such as fruits, vegetables, leftovers and other organic wastes that are in the residual waste.

The two counter-rotating rollers 454, 455 pull the waste 453 over the hopper 456 and grind or crush the waste much like applesauce. The Mus 457 is mixed with the overflow water 452 and leaves the device via drain 458 in the direction of pulper Il 1.1.

The radially non-movable roller 454 is driven via a variable speed gear 454.1 and has a higher speed than the auspendelnde counter roll 455. Through this device, the pull-in and squeezing effect is sustainably improved. The counter-roll 455 also has a speed-controlled drive 455.1.

The distance S between the two rollers 454, 455 is set to about 1 mm.

If refractory solid parts are drawn in (eg stones in vegetables or potatoes), the roller 455 has a pressing and articulating device 459, here represented by a pneumatic device with piston 459 and compressor 460. The deflection 461 is limited to max. 50mm, if exceeded, the system will be shut down and the foreign matter removed. FIG. 12 shows a corrugation 462 on the roll surfaces, which, as shown (see FIG. 15), extend at an angle of 45 ° to the running axis. The width b and the depth t of the corrugation 462 is approximately between 6 to 10mm. The distance a is about 100mm.

The above-described mechanical devices according to FIGS. 5 to 16 can also be used in the methods according to FIGS. 1 to 3.

Disclosed is a method for the treatment of non-depositable waste with organic components in which after dissolution of organic components in a pulper a separation of a substance obtained in the pulper suspension is carried out, which can then be fed as organik highly charged circulating water fermentation, and a waste treatment plant to carry out this process.
