Description
Technical field
The invention belongs to petrochemical industry, be specifically related to a kind of oil-polluted water oil expeller.
Background technology
In oil refining and petrochemical industry, chemical fibre, pharmacy and food industry, often carry all kinds of sump oils in the factory effluent secretly, not only the production wastewater treatment facility is brought bigger pressure, also caused the waste of oil product.The conventional treatment resourcefulness adopts and improves the water pot time of staying, sedimentation separation, centrifugation or carry out water-oil separating by modes such as oil removals in sewage treatment plant, these measures all have the problem that investment is high, occupation of land is big, efficient is lower, cause the cost of oil-polluted water oil removing higher.
Oil-polluted water separating treatment equipment is widely used industrial at present, particularly in the sewage disposal field of purification.In the existing oily waste water treatment flow process of China, adopt the method for advection oil separation tank in a large number, this oil interceptor is opened wide, and not only contaminated environment, and floor space is big, invests also high.Development in recent years a lot of new technologies all be to work aspect equipment volume, simplified structure, minimizing investment and the maintenance capacity reducing.
The patent disclosure of CN 2076097U a kind of band wing swash plate oil water separator (as shown in Figure 1) of oil-polluted water.This separator is characterised in that: housing is horizontal rectangle cylinder, and its cross section is square or rectangle; The structure of separator is by oil-polluted water import 1, homogenizing plate 2, sampling and testing mouth 3, housing 4, band wing swash plate filler 5, spoiler 6, oil trap 7, gas vent 8, oil-out 9, delivery port 10 compositions such as grade.This band wing swash plate oil water separator has airtight, and volume is little, takes up an area of to lack the characteristics of small investment.But the housing of this design is horizontal rectangle cylinder, its cross section is square or rectangle, and mostly be pressure vessel at the petroleum chemical industry oily water separating equipment, tank body is cylindrical, cross section is circular, this prior art is subjected to its structural limitations, is difficult to simply to divert from one use to another in the pressure vessel of circular cross-section to the petrochemical plant, is not suitable for being applied to the occasion of utilizing existing tank body to transform especially.
The patent disclosure of CN 1208111C a kind of crude oil electro-desalting dehydrator (as shown in Figure 2) that is used for petroleum chemical industry, make the voltolisation knot effect reduction of forceful electric power place in order to solve existing electric desalting and dewatering device existing employing weak electric field charging, crude oil flows and problems such as retardance drops of water fall down from bottom to top, its structure comprises a horizontal cylinder type tank body 1, one end of tank body 1 is a profit compound arrival end, the other end is the cleaned crude oil port of export, the top of the tank body 1 cleaned crude oil port of export is provided with flowline 10, it is characterized in that: axially be provided with the coalescent district 5 of feed distributor 4 and highfield successively from profit compound arrival end along tank body 1 in the tank body 1, the coalescent district 5 of highfield is provided with the flat-type pole plate 6 of the axially parallel of at least two floor and tank body 1, be parallel to each other between each layer battery lead plate 6, described feed distributor 4 correspondingly is provided with spout respectively with respect to the space between all adjacent two layers battery lead plates 6 in the coalescent district 5 of highfield.This prior art mainly is that the effect of using electric field separates profit, and most oily water separating equipments only are to separate by the gravitational difference of profit in petrochemical plant, can not all add electric field and promote water-oil separating.Therefore be not suitable for extensive employing.
Summary of the invention
For the gun barrel oil-water separation that solves prior art poor, the oil content height of device sewage discharge, the problem that the sewage disposal system load is high, simultaneously in order to make full use of the oil water separator tank body of existing apparatus, under the situation of not introducing electric field, improve oil-water separation, improve water-oil separating efficient, reduce to take up an area of, the utility model provides a kind of oil-polluted water oil expeller by improving the knockout drum internal structure.
Oil-polluted water oil expeller of the present utility model is achieved in that
