WO2003035578A1 - Ceramic filtering element and method for producing said element - Google Patents

Abstract

The invention relates to filtering devices, in particular to the structural design of disk ceramic filters and the method of production thereof. In order to increase the efficiency of a device, the filtering frame of the inventive filtering element is formed by spherical particles of electrocorundum having the ratio of sizes thereof which varies in a direction towards the filtrate output. The internal elements of said device are disposed in parallel rows in two reciprocally perpendicular directions, each element comprising two truncated cones which are embodied in the form of an integral part of the frame and connected to each other by the surfaces of the cross section thereof. The inventive method for producing said ceramic filtering element consists in introducing the M40 electrocorundum, a betonite and a sulphate-alcohol mash in the form of a technological binder into a plastic mixture during the preparation thereof. Two compounds of a porous carrier are pressed during formation in such a way that they are mirror-imaged and sintered at a fusion temperature of the betonite. Prior to assembling, the mounting planes of the thus produced elements are worked out and the gluing components are applied thereto.

One well-known method of manufacturing the filter element in many cases does not allow one to receive a simple dispensation. The membranous layer is designed to establish the network of defects due to shrinkage during drying and sintering, depending on the concentration of the liquid in the suspension and the concentration of the concentrate. This leads to a decrease in the productivity of the device.

1.3. Sulphate-brewery (PRS). 0 1.4. Χ ο ρ ρ φ φ связ связ ующее ующее ующее С С С С С С С С С С С С С. 6

2. Elec- tron Μ40, bentonite and PRS with a constant content of components 70: 23: 7, respectively, were placed in the mixer and the mixture was homogenized for 30 minutes.

The resulting plastic mass was coagulated by sowing through a system of 1 mm.

3. The calculated quantity of bulk material was placed in a detachable cavity and produced by compression at a specific pressure of 50 kg / cm. As a result of the transfer of the payout to the fixed value, we received the bills of the carrier of the given size and the configuration.

4. Preparations were available for 24 hours at a room temperature and placed in a dryer. The drying unit was maintained in the range of 75 + 5 C, and the heat recovery was 12 hours. 5. Dried preparations with a residual humidity of 0.1-

0.2% were placed on karma plundovyh plates and burned, i.e. secreting, for example, at a temperature of 1250 + 50 ° С, with heat exchanger for two hours. After burning, we made a visual contact for the presence of deformations, chips and tears. The standard experimental samples were examined for their flatness, accessibility, accessibility, and standard methods. In Table 1, samples and samples of materials obtained as a result of the average of ten measurements are shown.

On the adhesive side, applied to spraying materials, use a dispersed mixture made up of an electromechanical compound that is connected to 50 and aluminum The main part of the pressurized carrier was thrown off the accessory, with such a condition that there was no dispensation. 7 Spray the adhesive mixture and apply a tax on the ceramic carrier with a sprinkler spray. The bulk was maintained at a room temperature and on a quick working surface was applied a material of 5 membranes.

8. For the application of the membrane layer, a disperse system was used, containing 65> electromotive force and 35% EC. After thorough homogenization in the mixer for 40-50 minutes, the disperse system was applied by spraying on the work

15 9. As a result of preliminary studies, a dependence of the change in the adhesion factor on the shift of the membrane is observed in the case of the loss of property of the joint To learn about the dependencies of the thermo processing machine, you have to go to the tempera

20 300 + 50 ° C.

As a result of extracting at a temperature of 300 ° C for 10-15 hours, the membrane was fixed on a direct-coupled carrier with a shift of 13 + 2 °. With an increase in the temperature, the shear stresses decrease significantly.

25 10. The obtained industrial clean filter elements after processing were subjected to visual control and tests using standard methods. The visual panel did not reveal any distortions in the geometry, except for an increase of “40” times at the turn of the membrane, no defects were found in the form of messages,

30 holes or swellings. There are no tests between the two components of the media, the seam is barely noticeable.

1 1. The data in Table 2 illustrates that the proposed method will benefit from the use of portable filters, and that they are free of charge.

35 elements make it possible to increase the working pressure of the filter and the efficiency of the filter system as a whole.

The process of processing and the temperature of the process of receiving the maximum direct connections of the membrane layer with the direct carrier ensures the termination of the process

40 aluminum binder with a material of a filler and 8 of the carrier, which results in the formation of chemical bonds, an increase in adhesion, and, as a consequence, an increase in the shear strength between the membrane and the mainstream.

The device works as follows

If the unit is equipped with a 5-channel ceramic filter, the unit is sealed with a removable universal shaft, and there are 36 external connectors. A ceramic disk filter is composed of twelve ceramic filter elements. When the filter shaft is rotated, a ceramic filter element of the disk 5 ceramic filter is partially loaded in the media, Β ρezulτaτe οτsοsa cheρez πusτοτely shaft nachinaeτsya προtsess φilτρatsii cheρez πορisτy φilτρuyuschy κaρκas 1 and 2. vnuτρennie elemenτy Φilτρaτ sοbiρaeτsya in πusτοτelοm οbeme 4 οbρazuemοm πορisτym φilτρuyuschim κaρκasοm 0 1 vnuτρennimi elemenτami 2 and 3. bοκοvymi sτenκami Pοsτuπayuschy φilτρaτ udalyaeτsya cheρez οτvοdyaschy πaτρubοκ 5, section Quickly remove the unit volume at least the volume of the emptying filter.

In case of filtering of case 1, the other 5 plants are removed, which is removed due to the installation of the input to the device. The cleaned sediment is a ceramic filter element which is convenient for use with the following loading cycles for the material that is in need of service. 10 Β ρezulτaτe mnοgοκρaτnοgο, tsiκlichesκοgο isποlzοvaniya disκοvοgο κeρamichesκοgο φilτρa on φilτρuyuschey ποveρχnοsτi πορisτοgο κaρκasa 1 οbρazueτsya τοnκy slοy οτφilτροvannοgο οsadκa, κοτορy not udalyaeτsya sκρebκοm.

In the case of regeneration, the internal elements 2 carry out the role of a stability factor that increases the integrity of the whole operation.

After regeneration, a ceramic filter element 0 is used in the following multiple cyclic conditions in the case of a disk ceramic filter.
