Description
Technical Field
The utility model belongs to a filter device in oil field sewage treatment and other waste water recycling technologies, in particular to a filter gas-liquid mixing backwashing water collecting device.
Background
When the oil field oily sewage filter is used, a large amount of oil stains are accumulated on the surface of a filter material in the filter for a long time, partial oil stains on the surface can be taken away through backwashing of the filter in the initial filtering stage, but a small amount of residual oil stains are still always adhered to the surface of the filter material, and after long-term operation, the phenomenon that the filter material is adhered, hardened and the like is caused due to excessive accumulation of stubborn oil stains, so that the treatment effect is reduced, and the water quality does not reach the standard. Aiming at the problems, the conventional filter mostly adopts the method of installing the stirrer to break up the filter material, so that the filter material is mutually separated by means of external force to finish the purpose of deep backwashing, but the method also has many defects, such as higher manufacturing cost of the stirrer, complex installation and maintenance, large electric energy consumption, liquid leakage of an oil seal of the stirrer, difficult judgment of faults and the like.

The utility model discloses a filter gas-liquid mixture backwash water-collecting device comprises a jar body, is equipped with the inlet on jar body upper portion, is equipped with the back flush mouth in the bottom, jar internal lower part is equipped with the water collector baffle and divide into the filtering area on upper portion and the catchment area of lower part with it, has the precoat above the water collector baffle, is equipped with gas distribution cap screen pipe and water distribution cap screen pipe on the water collector baffle, gas distribution cap screen pipe passes through communicating pipe and inlet manifold intercommunication.
As a further improvement of the utility model, more than one water distribution cap sieve tube is uniformly distributed on the water collector clapboard in an annular shape.
As a further improvement of the utility model, more than one gas distribution cap sieve tube is uniformly distributed on the water collector clapboard in an annular shape.
As a further improvement of the utility model, the water collector clapboard is provided with more than one group of annular gas distribution cap sieve tubes and annular water distribution cap sieve tubes.
As a further improvement of the utility model, an annular gas distribution pipe is fixed below the water collector partition plate and is communicated with the gas inlet header pipe through a communicating pipe, and the annular gas distribution pipe is provided with a gas outlet at intervals and is communicated with the gas distribution cap sieve pipe respectively.
The utility model discloses a filter gas-liquid mixture backwash water-collecting device compact structure, area is little, utilizes the automatic control procedure to realize that backwash water and compressed air are reasonable in turn to be interrupted and wash, replaces the agitator to carry out the degree of depth backwash, reduces and makes and installation cost, and many filters can a jointly use compressed air source, compares many agitator motors and can save a large amount of energy.

Detailed Description
The utility model relates to a gas-liquid mixing backwashing water collecting device of a filter, which consists of a tank body 1, wherein the upper part of the tank body 1 is provided with a liquid inlet, the bottom is provided with a backwashing port 2 (filtering water outlet), the lower part in the tank body 1 is provided with a water collector clapboard 3 which divides the water collector into an upper filtering area 4 and a lower water collecting area 5, a filter material layer 6 is arranged above the water collector clapboard 3, more than one water distribution cap sieve pipes 8 are uniformly distributed on the water collector clapboard 3 in an annular shape, the bottom end of more than one supporting pipe 14 is fixed on the lower part of the inner surface of the tank body 1, the upper end is connected with the lower surface of the water collector clapboard 3 for supporting the water collector clapboard 3, oily sewage enters from the upper part liquid inlet of the tank body 1, after being filtered by the filter material layer 6, the water distribution cap sieve pipes 8 fixed on the water collector clapboard 3 obstruct, the filtering is finished by the back flushing water pipe 13 connected with the back flushing port 2 and flowing out of the device.
More than one gas distribution cap sieve tube 7 is uniformly distributed on the water collector clapboard 3 in an annular shape, an annular gas distribution tube 11 is fixed below the water collector clapboard 3 and is communicated with a gas inlet main pipe 10 through a communicating tube 9, gas outlets are arranged on the annular gas distribution tube 11 at intervals and are respectively communicated with the gas distribution cap sieve tube 7, and a gas inlet control valve 12 is arranged on the gas inlet main pipe 10. When the filtering period is finished, a backwashing period is started, backwashing water enters from a backwashing water pipe 13 connected with a backwashing port 2 at the bottom of the tank body 1, water uniformly flows out through a water distribution cap sieve pipe 8 uniformly distributed on a water collector partition plate 3 to scour a filter material layer 6, meanwhile, compressed air enters from an air inlet main pipe 10, air is controlled by an air inlet control valve 12 to enter a communicating pipe 9 and an annular air distribution pipe 11 through the air inlet main pipe 10, the compressed air is uniformly distributed at each part of the annular air distribution pipe 11, a large amount of bubbles with different sizes are released at the bottom layer of the filter material layer 6 through the air distribution cap sieve pipe 7, the bubbles quickly float up at the bottom of the water and the filter material in the filter material layer 6, the filter material layer 6 is impacted by self pressure, the structure of the filter material layer 6 is damaged, and the filter material completes.
The automatic control program controls the switching time and the size of the air inlet control valve 12, meanwhile, the purpose of gas-liquid alternative periodical backwashing is achieved according to the set switching time length and the backwashing water time length, the backwashing frequency and the backwashing period can be set according to the use working conditions and the treatment effects of different filters, the air source condition and the backwashing state of the filters can be remotely monitored, and the purpose of periodical automatic backwashing is achieved.
