Description

Efficient unpowered oily water separation retrieving arrangement
Technical field
The utility model relates to a kind of unpowered oily-water seperating equipment, is specifically designed to industry and catering trade.The industry oily water treatment is mainly used in all oils waste water such as harbour ballasting waste water, cold rolling mill waste water, oil product storehouse waste water, profit re-injection water; The catering trade oily water treatment is used for washing the dishes in the kitchen and rinsing a pot waste water.Sewage disposal relies on the hydromeehanics of liquid, and promptly the potential energy physical property that is converted into kinetic energy is carried out oily water separation.
Background technology
You Heshui in the oily(waste)water is separated from one another, following several method is roughly arranged: gravity separation, air supporting, absorption, high-speed rotational and biological oxidation process etc.They have is not suitable for plant-scale sewage disposal, and what have has its limitation in the use.
The processing of so-called oily(waste)water is meant and will flies at the oil slick and the whole or most removals of other suspended substance on sewage surface.If deal with satisfiedly, then will alleviate the burden of the advanced treatment of carrying out subsequently greatly, make new step of design level rising of entire sewage treatment project, and save investment, reduction day-to-day operation expense.
The traditional technology of oily water treatment generally adopts parallel flow intercepter, utilizes scraper plate that oil is concentrated in the oil trap, receives oil by belt; Or utilize the residence time of large-scale oil storage tank to collect oil slick.And to make this kind equipment effectively a primary condition of work be at equipment and enter and between the sewage of this equipment minimum velocity contrast can only be arranged that horizontal flow velocity need be controlled at 10mm/s, 2~3 hours residence time, otherwise just can't effectively work.So when the oily(waste)water quantity discharged is very big, must builds the considerable equalizing tank of some volumes or a plurality of oil traps are taken turns to operate, this will increase the initial cost and the floor space of engineering, cost of investment is strengthened, its complex structure is safeguarded the cleaning difficulty simultaneously, and running cost is also high.
Summary of the invention:
The purpose of this utility model is at present oily(waste)water treatment technology deficiency, a kind of treatment effect height that provides, good separating effect, use cost is low, need not additionaling power, the hydromeehanics of using liquid, promptly the potential energy science dialectical relationship that is converted into kinetic energy and Prandtl turbulent boundary layer principle and " turbulent flow becomes laminar flow " with the greasy dirt in the waste water efficiently, continuously, Separation and Recovery is handled fast.The utility model designs efficient unpowered oily water separation retrieving arrangement, comprising: casing, and water-in, water outlet is characterized in that: being provided with grid in the casing water inlet, is the disengaging zone in the space of grid bottom; At the rear portion, disengaging zone is the turbulent region, and two leaf turbulence plates are installed on the box bottom of turbulent region, is provided with baffle plate above two leaf turbulence plates, is connected with the following current plate in the front portion of two leaf turbulence plates; The rear portion of turbulent region is a reserve in casing, and the casing top of reserve is connected with the cavity of a bottom opening, is provided with oil outlet on the top of cavity; The rear portion of reserve is a clear water zone in casing, the bottom half at clear water zone place is provided with the weir flow plate, the casing top at clear water zone place offers water outlet, it is characterized in that: two leaf turbulence plates be two be 135 the degree angled surfaces form by the plate of lateral wave bar, anter and tank floor are 15 degree and tilt, and the length of rear panel is half of anter.It is characterized in that: reserve is more than two.It is characterized in that: the bottom half at disengaging zone and reserve offers blow-off pipe.It is characterized in that: the top at cavity is provided with cover plate.Effect of the present utility model is: this device has been realized the dynamic processes of sewage, and is consistent with the later stage advanced treatment process of the actual discharge situation of sewage and sewage; This device treating processes does not consume any power, and the energy has promptly been realized unpowered treating processes; Dwell time of sewage is lacked 30---40 seconds, horizontal flow velocity reached 70---80 millimeters or higher in this device treating processes, has shortened the residence time greatly, has reduced volume of equipment, saves floor space and cost; No any consumptive material in this device operational process need not to add medicament, no working cost; This device is easy to use, need not special messenger's during-operation service, only needs regular oil extraction to get final product; Water inlet oil-containing kind and oil-feed concentration are unrestricted, have been widely used in the processing of industry, elevator and food and drink oily water separation.
