Description
Technical field:
The utility model relates to the used oil removal plant in oil-contaminated water of oil field field, particularly agglomerated air floatation oil eliminator.
Background technology:
In the oil-contaminated water of oil field treatment process, what oil removing was partly adopted is that natural subsidence is removed oil tank, coagulant precipitation removes oil tank, the coagulation swash plate removes oil tank, waste-oil scavengers such as transverse flow oily(waste)water oil eliminator, natural subsidence is removed oil tank, coagulant precipitation removes the gravity oil-removing principle that oil tank adopts the profit density difference, its oil removal efficiency is lower: the coagulation swash plate removes oil tank, transverse flow oily(waste)water oil eliminator is according to " shallow pool theory ", device interior has adopted multi-form filler group, shortened oil droplet buoyance lift height, improve oil removal efficiency, but basic theories still is the gravity oil-removing principle that profit density is closed, and deoiling effect is also bad.
In the oil conte, sewage treatment device that Daqing oil field adopts at present, waste-oil scavenger is a kind of indispensable oil conte, sewage treatment device.The method of oily(waste)water oil removing both at home and abroad is many at present, that now uses mainly contains natural subsidence except that oil tank, coagulant precipitation remove oil tank, the coagulation swash plate removes oil tank, transverse flow oily(waste)water oil eliminator, natural subsidence is removed oil tank, coagulant precipitation removes three kinds of problems that the waste-oil scavenger oil removal efficiency is low, equipment volume is big of oil tank except that oil tank, coagulation swash plate: though worked out the transverse flow oily(waste)water oil eliminator of small-sized efficient in recent years, though significantly improved oil removal efficiency, can't satisfy the needs of oil field development from now on.
The utility model content:
In order to overcome the low and big deficiency of equipment volume of existing waste-oil scavenger oil removal efficiency, the utility model provides a kind of agglomerated air floatation oil eliminator, and this oil eliminator has oil removal efficiency height and the little characteristics of volume.
The technical solution of the utility model is: the agglomerated air floatation oil eliminator comprises cylindrical shell, overhead gage, weir board and baffle plate, the top of cylindrical shell and bottom are equipped with oil exit pipe and air supporting pipe assembly respectively, and the termination of oil exit pipe and air supporting pipe assembly places between overhead gage and baffle plate and weir board and the baffle plate; The water inlet pipe that connects the coalescing element assembly of air flotation zone is installed in the space of being made up of cylindrical shell, baffle plate and right end socket, and header and oil exit pipe are installed in the bottom and the top in this district.
The beneficial effect that the utlity model has is: the top of this oil eliminator cylindrical shell and bottom are equipped with oil exit pipe and air supporting pipe assembly respectively, the termination of oil exit pipe and air supporting pipe assembly places between overhead gage and baffle plate and weir board and the baffle plate, collection filler degreasing technique, air supporting blanking oil tech are combined in the pressure horizontal container, replace original natural subsidence to remove oil tank, coagulant precipitation and removed oil tank, coagulation swash plate and remove oil tank, transverse flow oily(waste)water oil eliminator, air supporting and select oil eliminator, realized the assemblingization, integrated of equipment; After air supporting choosing is placed on coalescing-plate and spacer plate, overcome transverse flow oily(waste)water oil eliminator little oil droplet has been removed relatively poor shortcoming, change air supporting blanking oil tech and be applied in the interior common process of uncovered equipment, improved the efficient of equipment oil removing, guarantee the influent quality of filtration grade, simplify technical process, reduced equipment volume, reduced floor space.
