Description
Technical field
The utility model relates to a kind of filter, is specifically related to a kind of oil field produced water treatment Two-layer filter.
Background technology
Daqing oil field has been implemented tertiary oil recovery technology on a large scale at present.Wherein, lowly carry out large-scale industrialization promotion containing poly-polymer flooding oil-extraction technique, highly reached at present the industrial test stage containing poly-polymer flooding oil-extraction technique and alkaline surfactant polymer flooding oil-field technique.
In treatment Technology for Petroleum Water Flooding, filtration fraction adopts pressure type individual layer filtrate filter, pressure type double-layer filter material filter, walnut shell filter, fibrous nodules filter, oil field at home sewage disposal is substantially all water drive oil-polluted water at present, and wherein oil field produced water treatment Double-filter material filter is widely used in the produced water treatment of oilfield water flooding DP technology.In the test of tertiary oil recovery produced water treatment process, particularly, in Disposal Process for Produced Water of Polymer Flooding, carry out large-scale industrialization popularization.
Double-filter material filter, in oilfield water technology, is the best filter of water treatment effect.But, owing to containing the polymer that viscosity is very high in tertiary oil recovery produced water, polymer adheres on filtrate together with crude oil, and in 100mm～200mm top layer, filtrate top layer, the crude oil and the suspended solid that dam are maximum, form both surface filtration, lower floor's filtrate role is very little, causes shorten filter cycle, and effluent quality is poor, meanwhile, structurally also there is certain defect.
One of existing Double-filter material filter defect is: backwash drain receiver (filtered water inlet distributor) is radial stainless steel screen casing.After screen casing focuses on middle part house steward, by the side water outlet of upper cover bottom, so just causing end socket top is dead space, become oil-collecting bag, each backwash crude oil all some row is not gone out, while again filtration, the crude oil that row does not go out is fallen filtering layer surface, affects filter effect and effluent quality.
Two of defect is: backwash water distribution system arm also adopts stainless steel screen casing, form rich font water distribution system with distributing main, because having carbon steel, stainless steel screen casing liner strengthens inner tube, between two pipes, fouling is serious, form and stop up, stainless steel screen casing percent opening is high, centre water outlet is many, edge water outlet is few, make backwash water distribution inhomogeneous, centre water outlet is many, while exceeding specified back washing strength, wash away padding layer, make filter tank centre leak filtrate, edge water outlet is few, while not reaching specified back washing strength, cause filtrate to harden, caking when serious, when filtration, seldom work, because stainless steel screen casing percent opening is high, upper surface water outlet is many, lower surface water outlet is few, cause in the end socket below backwash water distribution system, accumulate mud and crude oil, when filtration, make effluent quality variation.
Three of defect is: filter tank forms after both surface filtration, and filtrate and the crude oil caking that sticks together, can not smash, and makes backwash regeneration not thorough, works after a period of time, affects effluent quality.
Utility model content
The utility model is short filter cycle for solving existing oil field extracted water Double-filter material filter, the problem that effluent quality is poor, and then a kind of oil field produced water treatment Two-layer filter is proposed.
The utility model takes technical scheme to be for addressing the above problem: the utility model comprises motor, decelerator, reducer stent, oil slick collector, filter inleting pipe, upper ellipse head, filter tank cylindrical shell, lower ellipse head, skirt, filter out water pipe, shaft, filtrate disperses regenerator, anti-plate resistance gauge and backwash distribution device, upper ellipse head, filter tank cylindrical shell and lower ellipse head connect to form tank body from top to bottom successively, oil slick collector is arranged on the upper surface of described tank body, decelerator is arranged on oil slick collector by reducer stent, and the turning cylinder of motor is connected with the upper end of shaft by decelerator, and filtrate disperses regenerator, anti-plate resistance gauge and backwash distribution device are from top to bottom successively set in described tank body, the lower end of shaft is inserted in described tank body, and the lower end of shaft disperses regenerator to be connected with filtrate, filter inleting pipe is communicated with oil slick collector, filter out water pipe and be communicated with described tank body, described tank body is fixedly mounted on skirt.
The beneficial effects of the utility model are: the utility model backwash is totally thorough, solve the harden problem of long-pending oil, deposition of filter both surface filtration, top layer filtrate, extended more than 1 times the filter cycle of filter, solve the problems such as in backwash water distribution system bilayer sleeve fouling obstruction, low head, padding layer punching does not wash clean, backwash water distribution is inhomogeneous, leakage material, thereby ensured that effluent quality reaches oil-field flooding water quality index.
