Abstract
An efficient energy-conservation and gas-flushing filter used in an oil field comprises a filtering tank (10). A dirt collection hopper (11) is installed on the top of the filtering tank (10); the dirt collection hopper (11) is communicated with a back flushing water outlet pipe (15); the back flushing water outlet pipe (15) above a back flushing water outlet valve (4) is communicated with a water inlet pipe (16) before filtration; a water outlet pipe (13) after filtration is communicated with the bottom part of the filtering tank (10); a strong-force back flushing pipe (12) is communicated with the side wall of the filtering tank (10); the strong-force back flushing pipe (12) is communicated with a back flushing water inlet pipe (14); and a blender inlet valve (7), a blender (9 ), a compressed air pipe(12) with a compressed air valve (8) and a back flushing inlet valve (3) are connected with the back flushing water inlet pipe (14) in sequence. The filtering device solves the hardening problem by using the strong-force gas-flushing to loosen filtering materials on the bottom part of the filtering tank, utilizes the inside blender to mix gas and water, utilizes the dirt collection hopper technology to collect dirt at a large area, and realize the dissolved air flotation and slagging process.
Description
Technical field:
The utility model relates to a kind of oil field sewage treating equipment, especially a kind of energy-efficient air purge filter.
Background technology:
Along with domestic and international tertiary oil production in oil field, poly-to drive, the carrying out of combination flooding, the processing of extraction liquid becomes increasingly complex, and the advanced treating of oil-polluted water, condition are more and more harsher, require more and more higher to filter in the sewage disposal process.At present, known filter plant adopts tradition closed, promptly " pressure cooker cook congee " formula, often needs to change filtrate common filtering tank operational effect instability, and main cause is: the one, the greasy dirt that filter material surface adheres in the backwash process does not all separate; The 2nd, isolated greasy dirt does not have effective blowdown measure, causes blowdown not thorough, and most of greasy dirt is still stayed in the jar.
The utility model content:
In order to overcome the deficiency that exists in the background technology, the utility model provides a kind of energy-efficient air purge filter, this device solves the problem that hardens by the loosening filter tank of powerful air purge bottom filtrate, utilize inner vortex mixer to carry out the air water mixing and utilize dirt collecting bucket technology large tracts of land to receive dirt, realize the air-dissolving air-float tapping process.
The technical solution of the utility model is: this oil field air purge filter comprises filtering tank, the filtering tank tank deck is equipped with dirt collecting bucket, dirt collecting bucket is communicated with the backwash outlet pipe of band backwash outlet valve, the backwash outlet pipe of backwash outlet valve upstream is communicated with the preceding water inlet pipe of filter of band filtered water inlet valve, filtering tank bottom is communicated with outlet pipe after the filter of band filter back outlet valve, the filtering tank sidewall is communicated with the powerful backwash pipe that has powerful backwash valve, powerful backwash pipe is communicated with the backwash water inlet pipe, is connected with the vortex mixer inlet valve on the backwash water inlet pipe in turn, vortex mixer, the compressed air hose and the backwash water intaking valve that have compressed air valve.
Be communicated with antifreeze communicating pipe after the above-mentioned filter between outlet pipe and the backwash outlet pipe with antifreeze communicating valve.
The utlity model has following beneficial effect: water inlet of the present utility model is filtered the backwash blowdown and is adopted the i.e. mode of " laundry washer, rinsing " of open type design.(1) backwash: adopt the powerful fluidisation of compressed air, dissolved air water floats off device, by the filtrate that hardens in the loosening filter tank of powerful air purge bottom, the greasy dirt that adheres on the filtrate is effectively separated and floats to tank deck.(2) blowdown: adopt " dirt collecting bucket " of open type to reach " gas-liquid vortex mixer " device, utilize inner vortex mixer to carry out air water and mix, the greasy dirt that proportion is little is taken floating by molten gas bubble, be raised to overfall and freely flow out, at the bottom of heavy filtrate sinks to jar, avoid filtrate to run off; It is dirty to utilize dirt collecting bucket technology large tracts of land to receive, and the greasy dirt that floats to tank deck is all overflow to drain only, realizes the air-dissolving air-float tapping process.This device solves existing filter cleaning dirty, the obstruction, the uneven problem of mechanical agitation that occur,
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
The powerful backwash valve of 1-among the figure, 2-filter back outlet valve, 3-backwash water intaking valve, 4-backwash outlet valve, 5-filtered water inlet valve, 6-antifreeze communicating valve, 7-vortex mixer inlet valve, 8-compressed air valve, 9-vortex mixer, the 10-filtering tank, 11-dirt collecting bucket, the powerful backwash pipe of 12-, 13-filter back outlet pipe, 14-backwash water inlet pipe, 15-backwash outlet pipe, water inlet pipe before the 16-filter, antifreeze communicating pipe of 17-, 18-compressed air hose.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
