Description

Energy-efficient air purge filter
Technical field
The utility model relates to a kind of oil field sewage treating equipment, a kind of specifically energy-efficient air purge filter that can carry out advanced treating to oil-polluted water in the combination flooding produced liquid.
Background technology
Drive along with tertiary oil production in oil field is poly-, the carrying out of combination flooding, the processing of extraction liquid becomes increasingly complex, the requirement to filter in the advanced treatment process of oil-polluted water is more and more higher.And existing oilfield sewage filter plant adopts tradition closed, by filtrate is simply washed, finishes backwash.Owing to all separating, the common filtering tank greasy dirt that filter material surface adheres in backwash process do not need often to change filtrate, the 2nd, isolated greasy dirt does not have effective blowdown measure, cause blowdown not thorough, the part greasy dirt is still stayed in the jar, causes secondary pollution easily.
The utility model content
Cleaning dirty to oilfield sewage in order to overcome existing filter, improper and cause the deficiency of secondary pollution to the treatment measures of dirt in the backwash, the utility model provides a kind of energy-efficient air purge filter.This filter adopts compressed air that filtrate is stirred, and fluidisation is good, cleans the rate height, dirt in the filter tank all can be got rid of by dirt collecting bucket, avoids causing secondary pollution.
The technical solution of the utility model is: a kind of energy-efficient air purge filter, comprise the air purge filtering tank, and the dirt collecting bucket with backwash outlet pipe UNICOM is fixed at the top of described air purge filtering tank, water inlet pipe before the filter of backwash outlet pipe UNICOM; The sidewall UNICOM backwash air supply pipe of air purge filtering tank, the other end of backwash air supply pipe and backwash feed pipe UNICOM, and the two ends of backwash feed pipe respectively with vortex mixer and filter back outlet pipe UNICOM; The backwash water inlet pipe with air supply pipe UNICOM is fixed at the top of vortex mixer; Antifreeze communicating pipe mutual conduction is arranged between filter back outlet pipe and backwash outlet pipe; And corresponding respectively fixedly filtered water inlet valve, backwash outlet valve, filter back outlet valve, antifreeze communicating valve, backwash intake valve, water mix valve on water inlet pipe, backwash outlet pipe, filter back outlet pipe, antifreeze communicating pipe, backwash air supply pipe, backwash water inlet pipe, air supply pipe and the backwash feed pipe before the filter, gas mixes valve and backwash feed water valve.
The beneficial effects of the utility model are: owing to be provided with backwash air supply pipe, backwash feed pipe and vortex mixer in this device, adopt compressed air to the powerful gas backwash of filtrate in the air purge filtering tank, make the filtrate of filtering tank bottom loosening, solve the problem that hardens, make its fluidisation; Carry out the associating backwash again by vortex mixer then, thereby the greasy dirt that adheres on the filtrate is effectively separated and float to tank deck, collect greasy dirt and all excessive draining only by the dirt collecting bucket that is fixed on air purge filtering tank tank deck, not only oilfield sewage can be cleaned up but also can avoid causing secondary pollution.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Shown in accompanying drawing 1, this energy-efficient air purge filter mainly is made up of each pipeline of air purge filtering tank 3, dirt collecting bucket 4, vortex mixer 11 and UNICOM, the fixing dirt collecting bucket 4 in the top of air purge filtering tank 3 wherein, dirt collecting bucket 4 UNICOMs backwash outlet pipe 16, fixing backwash outlet valve 19 on the backwash outlet pipe 16; Water inlet pipe 2 UNICOMs before backwash outlet pipe 16 and the filter, fixing filtered water inlet valve 1 on the water inlet pipe 2 before the filter; The sidewall UNICOM backwash air supply pipe 5 of air purge filtering tank 3, fixing backwash intake valve 12 on the backwash air supply pipe 5, the other end of backwash air supply pipe 5 and backwash feed pipe 14 UNICOMs, and the upper end of backwash feed pipe 14 and vortex mixer 11 UNICOMs, lower end and filter back outlet pipe 18 UNICOMs, and fixing backwash feed water valve 13 on the backwash feed pipe 14, fixing filter back outlet valve 15 on the outlet pipe 18 of filter back; The top of vortex mixer 11 is backwash water inlet pipe 7 fixedly, and backwash water inlet pipe 7 and air supply pipe 10 UNICOMs, and fixedly mixed valve 8 of water and gas mix valve 9 respectively on the pipe (7,10); 16 of outlet pipe 18 and backwash outlet pipes have antifreeze communicating pipes 6 mutual conduction after filter, and should go up fixing antifreeze communicating valve 17 by pipe, prevent that pipeline from freezing because of variations in temperature.
During normal filtration sewage, open filtered water inlet valve 1, filter back outlet valve 15 and antifreeze communicating valve 17; After closing backwash feed water valve 13, backwash outlet valve 19, backwash intake valve 12, need to filter sewage and enter air purge filtering tank 3 along the top of filtering preceding water inlet pipe 2 and backwash outlet pipe 16, behind the media filtration in air purge filtering tank 3, flow out along filter back outlet pipe 18 and filter back outlet valve 15; When the dirt on the filtrate in the air purge filtering tank 3 need be cleared up, at first to carry out powerful gas backwash: start the air compressor machine that is connected with air supply pipe 10 this moment, close filtered water inlet valve 1, filter back outlet valve 15, antifreeze communicating valve 17, open backwash outlet valve 19, the mixed valve 9 of gas, backwash intake valve 12, after carrying out powerful gas backwash 3min, closing holds one's breath mixes valve 9.And then carry out air water associating backwash: start the backwashing pump that is connected with backwash feed water valve 13 this moment, fetch boiling water and mix valve 8, backwash feed water valve 13, oppositely supply water by filtering back outlet pipe 18 to air purge filtering tank 3, behind the washing 1min, open gas and mix valve 9, make air supply pipe 10 and 3 conductings of air purge filtering tank, carry out air water associating backwash, until the dirt on the filtrate is cleaned.After backwash finishes, stop air compressor machine, backwashing pump, closing holds one's breath mixes valve 9, water mixes valve 8, backwash feed water valve 13, backwash outlet valve 19; Open filtered water inlet valve 1, filter back outlet valve 15, antifreeze communicating valve 17, filter turns back to the normal filtration state and begins filtration cycle next time.
After this air purge filter utilizes air with pressure to carry out powerful air purge, carry out the air water mixing again and wash, utilize the interior isolated dirt of dirt collecting bucket 4 collecting tanks at air purge filtering tank 3 tops, realize the air-dissolving air-float tapping process.The greasy dirt that proportion is little is taken floating by molten gas bubble, be raised to overfall and freely flow out, and avoids causing secondary pollution, at the bottom of heavy filtrate sinks to jar, avoids filtrate to run off, and reduce production costs, and it is energy-conservation to handle the oil field wastewater efficient.
