Definitions

  • the invention relates to a process for the combustion of sewage sludge, in which the sewage sludge is dried by means of a dryer heated by a heat transfer medium and then burned in a furnace, in particular cycloidal combustion, in which the heat transfer medium is heated by the combustion and in which the flue gases from the furnace dedusting and flue gas cleaning.
  • Cycloidal firing in the description and in the claims is understood to mean a firing in which fuel is burned in a swirl flow. Vortex air is preferably fed into the combustion, as shown in Figure 3 on page E36.
  • cooling takes place in the waste heat boiler to 200 ° C., so that the filter ash drawn off in the fabric filter is contaminated with pollutants, in particular condensable heavy metals and their compounds, as well as products of incomplete combustion.
  • This object is achieved in that a basic additive is added to the furnace, then heat is removed from the flue gas for drying the sewage sludge while the flue gases are cooled to a first temperature above the condensation temperature of volatile heavy metals, followed by a first dedusting, then again from the flue gas Heat is extracted while cooling the flue gas to a lower temperature, but above the cooling limit temperature of the flue gas, then further basic additive is added to the flue gas and the flue gas is then fed to a filtering dedusting device.
  • the flue gases are preferably cooled from the combustion temperature to a temperature of 400-500 ° C, more preferably 420-470 ° C, even more preferably 450 ° C, and the cooling before the further addition of basic Additive to a temperature of 100-150 ° C, it being assumed that the furnace has a temperature of 1000-1100 ° C, preferably 1050 ° C.
  • a mixture of flying dust and the at least partially reacted basic additive is separated in the first dedusting.
  • This dust has essentially no condensed heavy metals and their compounds.
  • Subclaims 2-9 relate to further refinements of the method according to the invention.
  • the invention is also directed to a plant for the combustion of sewage sludge with a dryer for drying the sewage sludge, a combustion device downstream of the dryer, in particular cycloid firing, a heat sink downstream of the firing for the provision of heat for sewage sludge drying, dust separation and flue gas cleaning.
  • the system is characterized in that a device is provided for the supply of a basic additive for firing, that the dust separation is followed by a further heat sink and this is another device for the supply of basic additive, and that the further device is followed by a filtering dust separation .
  • a ploughshare mixer is shown as the dryer 3, the double jacket 3a of which is heated with steam.
  • the sludge is constantly whirled up and divided.
  • the residence time of the sludge is set so that the sludge is brought to over 80% DM, preferably 85-92% DM.
  • This dryer also works optimally when the sewage sludge passes through the glue phase during drying. As a result, it is not necessary to mix the sewage sludge with sludge that has already dried before entering the dryer.
  • the glue phase is determined by a dry matter content of 50 - 60% dry matter, within which the sewage sludge tends to stick together to such an extent that most dryer types including a disc dryer cannot process such a sludge.
  • an indirectly heated dryer can also be operated with heated thermal oil or with flue gases. It is only important that the drying takes place indirectly.
  • a metering device 5 which is shown in FIG. 1 is shown as a motor-driven discharge screw into a cycloid combustion chamber 6.
  • the cycloid combustion chamber is supplied with primary air PL via a blower 7 and a line 7a such that the primary air swirls into the combustion chamber via the lower combustion chamber cone 6a.
  • a start-up and support burner 8 and a secondary air supply 9 including a blower 10 are assigned to the combustion chamber. The combustion takes place automatically, i. H. the burner 8 is usually out of operation.
  • a basic additive, preferably hydrated lime, from a silo 12 is added to the secondary air SL via an injector 11a.
  • a first dry flue gas cleaning stage is implemented, since the combustion chamber 6 has a very balanced temperature distribution, preferably in the range of 900-1050 ° C. With this temperature distribution, very good integration of acidic noxious gas components, in particular SO x , can be achieved with the formation of the corresponding calcium compounds.
  • the flue gases then flow through a waste heat boiler 13 together with the fly ash formed during the combustion and the at least partially reacted additive in a water vapor circuit 14 with flow 14a and return 14b including a circuit pump 15 and a drum 16 in the from FIG. 1 apparent way is switched on by means of a feed line 13a from drum 16 and a discharge line 13b to drum 16.
  • the waste heat boiler is a saturated steam smoke tube boiler, as shown in FIG. 1 is shown. Steam is applied to the double jacket 3a of the dryer and the condensate that forms is returned to the drum via the pump 15.
  • the flue gases in the waste heat boiler 13 After the flue gases in the waste heat boiler 13 have cooled to a first temperature, preferably 450 ° C., the flue gases flow through a dust separator, which is preferably designed as a high-temperature cyclone 17.
  • a dust separator which is preferably designed as a high-temperature cyclone 17.
  • 90%, but preferably even more, of the entrained mixture of fly dust and reacted additive is separated out as the first product 18.
  • This product contains practically no condensed heavy metals and their compounds, as well as no products of incomplete combustion.
  • the high-temperature dedusting in the cyclone 17 is followed by a heat exchanger 19 in which heat is transferred to water, steam, air or the like.
  • a heat exchanger 19 in which heat is transferred to water, steam, air or the like.
  • water from the steam circuit associated with the waste heat boiler 13 can be preheated.
  • the flue gas cooled, for example, in the heat exchanger 19 to 200 ° C., is then fed to a quench 20, with the aid of which fresh water 21 is added to cool the flue gas to the operating temperature of a downstream, second, dry flue gas cleaning stage.
  • the operating temperature of this flue gas cleaning stage is above the cooling limit temperature (adiabatic saturation temperature) of the flue gases, preferably in the range of 100-150 ° C.
  • a basic additive preferably calcium hydrate.
  • the second flue gas cleaning stage represents fine cleaning with regard to the acidic harmful gas components and the substance.
  • a filter auxiliary layer is formed in the fabric filter 23 from the separated solids. The water accumulation in the flue gas due to the quenching is conducive to the separation performance of the fabric filter 23.
  • the solids separated in the fabric filter can be recirculated back into the flue gas stream upstream of the fabric filter 23 via a rotary valve 24 and a return line 25.
  • a partial stream 26 is discharged.
  • the second dry flue gas cleaning stage is followed by an activated coke filter 27, which fulfills a police filter function with regard to dust and acidic harmful gas components. With regard to mercury and organics, the fine cleaning function is fulfilled.
  • an activated coke filter a zeolite filter can also be used. Because of the low load, the filter material of the filter 27 can be exchanged at more or less long intervals. It is regenerated or, in the case of the activated coke, co-combustion in the furnace 6 can also be considered.
  • a suction fan 28 connects to the filter 27 and supplies the flue gases to a chimney (not shown).
  • the vapors formed during drying can be according to Figure 6 of page E40 of the aforementioned DE-Z. treated. However, in order to avoid a condensate to be treated separately, it is more expedient to feed the vapors directly to the furnace 6 via a line 29.
  • the additive for the second cleaning stage between quench 20 and fabric filter 23 is added.
  • it can also make sense to add the second additive between the heat exchanger 19 and the quench 20.
  • the secondary air is supplied in stages via lines 9a and 9b.
  • At least a partial flow of the flue gases leaving the furnace steam generated by heat exchange by means of the flue gases or air heated by heat exchange by means of the flue gases can be used as the heat carrier for indirect sewage sludge drying.
  • a cycle gas is used as the heat transfer medium for direct sewage sludge drying, preferably air and / or vapors formed during the drying, which is heated by heat exchange with the flue gases.
  • FIG. 2 An embodiment for the process control with direct sewage sludge drying will be based on FIG. 2 are described.
  • the same reference numerals have been adopted as far as possible for the same technical objects.
  • the sewage sludge is fed to a screw 29 by means of the sludge pump 2 and from there enters a fluid bed dryer 30.
  • the sludge layer is directly flowed through and thus dried by a heat transfer medium guided in a circuit 31, which essentially consists of those during drying vapors formed.
  • the vapors are fed via a vapor extraction line 31a to a fabric filter 32, in which they are dedusted. From there they are returned to the fluid bed dryer 30 via a circuit line 31b containing a vapor compressor 33 and a heat exchanger 34.
  • the heat exchanger 34 is switched on in the water-steam circuit 14 instead of the indirect heat dryer 3. With the help of the steam of the water-steam circuit 14, the vapors compressed in the vapor compressor 33 are brought to the required drying temperature.
  • fresh air may possibly be fed into the vapor circuit 31 upstream of the heat exchanger 34 via a fan 35.
  • a part of the vapors (evaporated water and possibly supplied air) is fed via a line 36 to the cycloid combustion chamber 6 with the interposition of a heat exchanger 37.
  • the heat exchanger 37 is comparable to the heat exchanger 19. In the heat exchanger 37, the heat to be removed from the flue gases after the dust separation 17 is transferred to the vapors to be fed to the cycloid combustion chamber 6.
  • the solids deposited on the fabric filter can also be fed to the screw 29 via a line 38 with the interposition of a buffer tank 39 and a screw conveyor 40 in order to adjust the consistency of the sewage sludge to be fed in the dryer (glue phase).
