Description

The invention relates to the treatment of wastewater from petroleum products and can

^{: to} be used on vehicles and industrial plants. The device contains a filtering layer of fibers 8 * fixed on the main perforated partitions 2 and 4. The partition 2 can be moved from the actuator 6 by means of a screw shaft 5. Between the partitions 2 and 4 there is an additional axially movable perforated partition 3 through which holes are passed ·· fibers 8. When filtering, the fibers are compressed and the liquid being cleaned passes through the nozzle 10, the filtering layer 8 and the nozzle 11. Regeneration is carried out by lowering the partition 2 and then the partition 3, simultaneously odavaya washing liquid through the nozzle 11.

When the septum is lowered, the 3 edges of its "holes" scrape dirt from ^ fibers 8, which are removed with flushing liquid through fitting 10. Socket 13 serves to remove floating pollutants. 2 Il.

The invention relates to the field of wastewater from petroleum products in a mixture with mechanical impurities and can be used in industrial plants and vehicles, in particular on ships.

The aim of the invention is to increase the efficiency of filter regeneration and reduce the consumption of wash water.

, Figure 1 shows a filter for liquids during the filtration process; figure 2 - the same, in the process of regeneration.

The filter includes a housing 1, in the cavity of which three perforated partitions 2-4 are placed. The partition 2 is movable and mounted on a screw shaft 5 connected to the drive 6. The partition 3 is also movable, mounted on the rod 7 and has the possibility of reciprocating movement along the fibers of the filter material 8.

The filter material 8 is made of. thread-like segments, passed through the holes of the perforated partition 3. The ends of the cut-offs are fixed on the partitions 2 and 4. The movement of the perforated partition 2 is limited by the stops 9 mounted on the wall of the housing 1. The movement of the perforated partition 3 during filter cleaning is limited to the top by the fixed perforated partition 4 and the bottom by the partition 2

On the housing 1 is placed a pipe 10 for supplying the cleaned fluid, a pipe 11 for draining the purified liquid, a pipe 12 for draining deposited sludge and a pipe 13 for draining pop-up sludge.

• The filter works as follows.

In the filtering mode (figure 1) the filter material 8 is in a compressed state. To compress the filter material, the partition 3 by moving the rod 7 lead in? the upper position is close to the partition 4, the partition 2 by means of the drive b approaches the partitions 3 and 4. The volume between the partitions 2 and 4 is reduced, and the filter material 8 is compressed. When filtering the original zhidkost pipe 10

enters the volume of the housing 1, passes through the perforated partition 2, the layer of compressed filter material 8 into the upper part of the filter housing and through the nozzle вывод1 is removed outside the filter. Passing through the filtering stream, the impurities present in the original liquid are retained in the pores of the filter material 8. After the pores of the filtering layer are filled with the impurities present in the original liquid, the filter is regenerated (FIG. 2). To do this, by means of the drive 6 and the screw shaft 5, the partition 2 moves up to y by _ _ 9, stretching the thread-like sections of the filtering material. To regenerate the filter, the washing fluid flows through the nozzle 10 into the cavity of the housing 1, passes along the fibers through the decompressed filtering material. Simultaneously with By this, the movable partition 3, by moving the stem 7, moves along the fibers of the filtering material 8 and cleans adhering contaminants from the fibers with the edges of its holes. outside the filter.

The filter regeneration efficiency using the third movable partition increases by about 15-20%, while the consumption of wash water is reduced by about 3 times.
