Description
Technical field
The utility model relates to a kind of oily-water seperating equipment, the device that particularly a kind of oil-contaminated water of oil field is processed.
Background technology
At present, oil field extracted water adopts the physico-chemical processes such as sedimentation, flocculation, filtration to carry out " two-part " or " syllogic " processing mostly.Will add a large amount of chemical agents during flocculation, settlement separate equipment also usually can not be brought into play due effect, is difficult to remove dispersed oil, the oil in water emulsion that particle diameter is less, increases the load of filter plant, causes filtrate to pollute, and makes the effluent quality variation.
Summary of the invention
The utility model purpose is to provide a kind of non-secondary pollution, the coalescent device of oil-contaminated water of oil field oil removing that oil removal efficiency is high.
The utility model comprises buffering system, coalescent deoiling system, and described buffering system is communicated with by pipeline with described coalescent deoiling system, described buffering system comprises the buffering tank body, top in described buffering tank body inboard arranges oil trap, lower end at described oil trap connects oil exit pipe, it is external that the exit end of described oil exit pipe stretches out surge tank, upper at described buffering tank body, bottom arranges respectively, lower clapboard, on described, filler particles thing carrier between lower clapboard, on described, lower clapboard is equipped with the hole that aperture is less than the particulate matter carrier, bottom at described buffering tank body arranges water inlet pipe, the exit end of described water inlet pipe is arranged on the top of lower clapboard, on buffering tank body below described lower clapboard, washpipe is set, lower end at described buffering tank body arranges sewage draining exit, described coalescent deoiling system comprises coalescent device tank body, top in described coalescent device tank body inboard arranges oil trap, lower end at described oil trap connects oil exit pipe, it is external that the exit end of described oil exit pipe stretches out coalescent shelf jar, some strata knot tyings are set in described aggregation apparatus tank body, bottom at described coalescent device tank body sets out water pipe, in the lower end of described coalescent device tank body, sewage draining exit is set, top at described buffering tank body arranges liquid-inlet pipe, and the entrance end of described liquid-inlet pipe is communicated with and is arranged on the below of described upper spacer with the buffering tank body, and it is interior and be arranged on the below of orlop coalescing-plate that the exit end of described liquid-inlet pipe stretches into coalescent device tank body.
The water inlet pipe of the utility model oily(waste)water from surge tank enters in the buffering tank body, particulate matter carrier buffering through particle diameter 1-2cm, this process can guarantee the coalescing-plate in the coalescent tank in back that passes through that oily(waste)water can be uniform and stable, and can remove solid particulate that particle diameter is large and oil slick etc.; Oily(waste)water after buffering enters in coalescent device tank body through liquid-inlet pipe, and oily(waste)water makes oily water separation through the effect of coalescing-plate, and the oil floating of separation enters in oil trap and discharges by oil exit pipe; The oil that this device is removed is all the oil droplet that more unmanageable particle diameter is less basically, and the oil content of wastewater fluctuation after this device is processed is less, is applicable to the further process of refinement in rear end; Have again that this plant area is little, efficiency is high, non-secondary pollution.
Coalescing-plate described in the utility model is a waviness plate body that is provided with down " V " shape elongated slot, on the upper top of " V " shape elongated slot of respectively falling of described plate body, some circular holes is set respectively; Described Circularhole diameter is 5mm; The oil removing principle of this coalescing-plate is: because the coalescing-plate special shape makes between coalescing-plate fluid velocity very little, in tiny oil droplets horizontal laminar flow process at the surface collision of coalescing-plate, coalescent, served as when droplet diameter is coalescent arrives certain particle diameter, oil droplet starts floating by the circular hole passage on inverted V-shape top, and then realizes the high efficiency separation of profit.
The exit of the water inlet pipe of the utility model on described buffering tank body arranges a baffle plate; Baffle plate is set and can prevents that oily(waste)water from altering groove, affect treatment effect.
The utility model arranges a feed liquor pipeline inlet baffle in the exit of described liquid-inlet pipe, be 60 ° of angles between described feed liquor pipeline inlet baffle and horizontal plane; This piece baffle plate is set and can plays endergonic effect to carrying out water slug, the ingress fluid velocity is little like this, and flow field disturbance on every side is also little.
