SU1214151A1 - Filter for purifying effluents containing petroleum - Google Patents

Description

"

The invention relates to devices: for treating liquids, containing organic petroleum fats, and also for the purification of household and industrial waste liquids and water from natural sources. .

The purpose of the invention is to impregnate the filtration process and increase the efficiency of cleaning oil-containing waste water by improving the quality of the regeneration of the filtering material.

FIG. Figure 1 shows the flash: {s in filter mode, cut; figure 2 - the same, in the regeneration mode

The filter consists of a housing 1, which has a square in cross section, sealed to the lid 2, where the pneumatic cylinder 3 is coaxially mounted with nozzles 4 for air supply and a rod 5, one end of which is the pneumatic cylinder piston 6 and the other Vision perforated partition 7, having the shape of a truncated pyramid A subdivision 7 partition 7 is located underneath the non-perforated partition 8. Above the partition 8 to the filter housing is attached a cutting stock 9 for supplying the treated water. Between the partitions 7 and 8 located elastish, for example, from polyurethane foam filtering material 10 In the thickness of the load there are vertical pipes 11 with shut-off valves 1–12 located in the upper part of the pipes IIJ serving for removal from saturation. The valves 12 have a means 13 for their vertical reciprocating movement and guides 4. Dp remove the filtrate serves as a pipe 5

The filter works as follows.

The cleaned fluid enters the filter housing 1, which is hermetically connected to the lid 2, on which the pneumatic cylinder 3 is coaxially mounted, is distributed through the pipe 9 to the fixed perforated partition 8 with the valves 12 closed.

in the polyurethane filter material 10, in the process of passing the waste liquid through the filter charge, the last in its

i; surface absorbs petroleum products from wastewater, resulting in cleaning of incoming fluid. The cleaned fluid passes through the perforations in the recess 7 and is discharged through the nozzle 15,

The regeneration is carried out with the nozzle 9 closed and the valves 12 open. The regeneration is carried out by pressing sorption oil

5 products from filtering material when supplying compressed air under the piston 6 of the pneumatic cylinder 3 through the nozzle 4, providing with the help of the rod 5 the possibility of moving the partition 0 1Ж 7 upwards, as a result of which the filtering material is compressed, oil products are squeezed out and reduced resistance wall layers of filtering material on the bottom of the filter housing, increasing the efficiency of extracting oil products during regeneration of the filtering material.

The pressed oil products are discharged through pipes 11 to a special tank (not shown). Thereafter, the valves 12 with the guides 14 by means of the means 13 are closed. The filtering process is repeated.

The estimation of the influence of the curvature of the drainage device on the efficiency of cleaning wastewater after regeneration of the filtering material is shown in the table.

Spin filter loading with a drainage device made in the form of a truncated pyramid with height h О, 1-0.15-V, where B is the width of a square, provides 26-35% increase in the efficiency of extraction of oil products, excluding caking of the filtering material, its destruction and removal purified water flow, facilitating the operation of the filter, intensifying the process

filtration, increasing the cleaning efficiency of oily waste 1x.
