Abstract
The invention provides a high-efficiency oil-water separation box and an oil-water separation device utilizing the oil-water separation box. The oil-water separation box is used for separating oil slick, dispersed oil and emulsified oil in oil-containing sewage. The oil-water separation box has a multi-faceted cylindrical box body. A bell mouth is arranged on the upper end of the box body, and a spigot is arranged on the lower end of the box body. An arc separation board is arranged inside the box body, and is placed on the upper rim of the convex of the upper end of the spigot on the lower end of the box body. With the separation board, the box body is divided into an upper-part oil-water separation space and a lower-part oil collection space. A plurality of water distribution guide nozzles arranged obliquely downwards along a clockwise direction are arranged on the arc separation board. An oil guide pipe is connected to the top outlet of the arc separation board. A multi-faceted conical super-lipophilic super-hydrophobic net is placed in the oil-water separation space. The oil-water separation device is formed by tiling and laminating the oil-water separation boxes in a honeycomb manner. According to the device, the plurality of oil-water separation boxes are laminated and form a multi-level series cyclone net collection oil-water separation body. Oil-water separation methods such as gravity separation, centrifugation and agglomeration are integrated. The device has the advantages of high oil separation efficiency, short retention time, smooth sludge discharge, and the like. When a demulsifier is added to a water inlet end, the oil-water separation device can also be used for removing a part of emulsified oil in the sewage, besides oil slick and dispersed oil.
Description
Technical field
The present invention relates to sewage treatment area, particularly relate to a kind of oil-water separation box of oily water treatment and utilize the oily-water seperating equipment of this Seperating box.
Background technology
Petrochemical complex, mechanical workout, the industry such as oilfield exploitation and food-processing can produce a large amount of oily(waste)waters, has serious hazardness to environment.The treatment process of oily(waste)water has gravitational separation process, coalescent method, absorption method, centrifuging, coacervation and flotation process etc., gravitational separation process is wherein a kind of conventional easy physical oil-removing method, it utilizes water-oil phase immiscible and there is density variation, realizes the floating upper of oil droplet and is separated.
Apply more gravitational separation process traditionally and mainly contain parallel flow intercepter and ramp type (dull and stereotyped or waved plate) oil trap.These oil traps, due to its constructional limitation, all have certain deficiency in oil removal efficiency etc.As parallel flow intercepter, by homogeneous plug-flow, whole pond body is considered that elaioleucite floats and is separated, easily cause the disturbance of elaioleucite floating-upward process large, separable oil droplet is limited to size, and separation efficiency is low, and oil removal tank volume is large.If tilted plate intercepter is flat board according to shallow pool theory inclined parallel in the body of pond or waved plate, shorten the floating distance of oil droplet like this, and collision coalescence of having an opportunity between oil droplet in swash plate chamber becomes the oil droplet of greater particle size, comparatively parallel flow intercepter increases on oil removal efficiency, reduce the residence time, but because of its oil and water contrary in the flow direction, and easy deposition blocking between swash plate, restrict further raising and the application of its oil removal efficiency to a certain extent.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of collection gravity separation, the oil-water separation method such as centrifugal and coalescent is in high efficiency oil-water Seperating box integrally and the oily-water seperating equipment utilizing this Seperating box.
Oil-water separation box of the present invention, have multi-faceted column shape box body, cassette upper end is provided with bellmouth, and lower end is provided with socket; The built-in arc-shaped partition of box body, is placed on edge on the tang of socket upper surface, box body lower end, box body is separated into oily water separation space, top and two, oil-collecting space, bottom part; The water distribution that arc-shaped partition is provided with multiple downward clockwise direction tilting leads mouth; The outlet of arc-shaped partition top connects an oil guide pipe; The super-hydrophobic net of the pyramidal super oleophylic of a multiaspect is placed in oily water separation space.
