Abstract

The filter relates to the field of water purification from petroleum products and mechanical impurities. In the filter in order to increase the reliability and durability of the filter, as well as simplify the fabrication and reduce the metal content of the structure, the axis of the filter cartridge 5 is located vertically, and the frame 9 is made of round perforated discs 10, mounted with the possibility of moving with equal intervals between them through the inner part of the cartridge 6, the rod 11 and attached peripherally at the places of their contact with the material 13. Between the disks 10 of the filter cartridge 5, springs of a smaller diameter can be installed, The diameter of the discs in this case does not require mounting the discs 10 to the filtering material 13. The filter housing may have a settling tank filled with granules. 2 hp f-ly. 4 il.

FIG.

The invention relates to filters for 1kt of iodine from oil products and mechanical impurities and allows to effectively exfoliate the emulsion, clean it from mechanical impurities, and also provides for the regeneration of the filter element without using wash water and disassembling the filter.

The purpose of the invention is to improve the reliability and durability of the filter, as well as to simplify the manufacture and reduce the metal content of the filter cartridge design.

Fig. 1 schematically shows a filter, a slit, Fig. 2 a perforated carcass disk, Fig. 3 a modification of the filter cartridge, a slit, Fig. 4 a filter with a sump, a slit.

The filter (Fig. 1) serves to purify the liquid from mechanical impurities, but it can also be used to strengthen the dispersion composition of the emulsion, which is then more efficiently separated in any standard sump. The filter includes a housing I with nozzles for supplying the original emulsion 2, removing the enlarged emulsion 3 and mechanical impurities 4, the filter cartridge 5 consisting of the filter element 6, the movable washer 7, the fixed washer 8, the frame 9 made of round perforated discs 10, freely mounted at equal intervals on the rod 11, which is connected to the movable washer 7 and out of the cinnamon 1 through the seal 12. The disk 10 on the periphery around the circumference when attached to the material 13 of the filter element 6.

And disks 10 jeiKO sets n frame 9 filter cartridge 5 of any desired diameter

FIG. 3 shows a modification of the filter cartridge 5 which does not require mounting the disks 10 to the filter element 6, and the gap between the disks 10 is provided by small diameter pads 14. Using small diameter pins 14 makes it cheaper and forgives making the frame 9 of the filter compared to a large spring frame diameter In addition, in the proposal of the amoi structure, the skew of frame 9 is eliminated during compression of the filter cartridge 5

Fig 4 shows a filler for cleaning, in the case 1 of which a settler 15 is placed, filled with granules 16 and having separate nozzles for outputting the separated oil products 17 and purified water 18.

The filter for cleaning the liquid works as follows.

The liquid to be cleaned, for example oil in the emulsion, is fed through the nozzle 2 into the volume of the housing 1 and passes through the filter element 6 into the inner part

filter cartridge 5. The passage through the coalescent material of the filter element b, the emulsion is cleaned of mechanical impurities and its dispersed composition is enlarged. Then, the purified from mechanical impurities and the enlarged emulsion is discharged from the housing 1 through the nozzle 3 and is easily separated in a standard sump. The pipe 4 for removal of mechanical impurities is closed. During the operation of the filter, the surface of the filter element 6 is clogged, which leads to an increase in the pressure drop across it. When a critical pressure drop is reached on the filter element 6, the pipes 2 and 3

5 is closed, and the filter cartridge 5 is periodically compressed when moving the rod 11 using a cam or crank mechanism (not shown). When compressing the filter cartridge 5, the filtrate from its volume flows back into the volume of the housing 1 through the filter element 6, flushing the filtered mechanical impurities that are removed from the housing 1 through the pipe 4. The efficiency of regenerating the filter element 5 and 6 also contributes to its deformation during periodic compression of the filter cartridge 5 After regeneration filtering process resumes.

The filter with the sump 15 (Fig. 4) is basically the same as

0 filter without sump 15 (Fig. 1). The difference lies in the fact that the oil tank on the emulsion, enlarged by the filter element 6, is not removed from the housing 1, but enters the settling tank 15, filled with granules 16, where its final

D) separation. Separated oil products are removed from the housing 1 through the pipe 17, and the water is purified from mechanical impurities and oil products through the pipe 18. The filter and the sump 15 are placed in one

The housing allows to reduce the size and intensity of the cleaning device as a whole and at the same time purify water from mechanical impurities and oil products.

Preliminary tests of the proposed 5 my filter showed the reliability of its work and the high quality of regeneration of the filter element. It was enough 4-5 compression of the filter element 6, so that the pressure drop across it was reduced to the original. Regeneration of the filter is simple and does not take much time, is carried out without washing water and disassembling the filter and can be carried out even during the operation of the filter.
