Abstract
An oil-water separator is composed of one or several oil-water separating units which are formed by superimposition. Each oil-water separating unit is a box without cover, which has a horizontal hydrophilic and oil-resistant filter layer in it, water inlet on its top, water outlet under it and a bottom plate inclinded with a 1-1.5% slope. The oil collecting tube for lower oil-water separating unit is under the highest point of the bottom plate for upper unit. The adjacent two units are sealed and superimposed together. An arch-shape sealing cover with oil collecting tube connected to a general conduit is installed to the top most unit. It can reduce the oil content in water from 1760 mg/L to less than 0.3 mg/L.
Description
The present invention relates to oily water separation technique.
Human pursuit is carried out high efficiency oily water separation technique to oil-containing water and has been experienced several centuries.It not only can reduce production costs significantly, but and energy savings and great amount of water resources, and ecological environment also played good effect.
In oily water separation technique, particularly the oily water separation technique of the Boiler Steam condensate water of oil-containing is had relatively high expectations, and difficulty is big, but benefit is also very obvious.
Boiler feed water, national Specification, deionized water that should the Seeking Truth desalination requires oil content must not surpass certain amount again, and for general boiler feed water, oil content must be not more than 1mg/L, and for the high-pressure boiler water, oil content must be not more than 0.3mg/L.
In the actual production of oil plant, the steam that boiler produces mainly contains two purposes, and the one, with being used as power, another purposes is used for heat supply.The steam of heat supply just is condensed into condensate water behind heat-exchange device, this water should be desalination, can reuse, but because in heat transfer process, heat-exchanger rig has oil leakage phenomenon inevitably, contain a certain amount of oil in the condensate water to making,, substantially exceed the standard of boiler feed water generally at 20--150mg/L.
Have not yet to see report not adding medicine make the device of water-oil separating effectively, also not being reported to make water-oil separating reach the oil-water separation system that the recycle-water oil content is not more than 1mg/L and 0.3mg/L.
The object of the present invention is to provide a kind of oil water separator efficiently, another object of the present invention provides and a kind ofly can make water-oil separating reach the oil-water separation system that the recycle-water oil content is lower than 1mg/L or 0.3mg/L.
The objective of the invention is to realize with following technical scheme:
A kind of oil water separator, it is made up of the stack of one or more water-oil separatings unit, each water-oil separating unit is a uncovered casing, the upper edge of wall box and lower edge end respectively have a circle flange, the hydrophilic oil resistance filtering layer of forming by the super hydrophilic oil resistance filter material of level at the middle part of casing, hydrophilic oil resistance filtering layer is separated into two parts with casing, and top is former hydroecium, and the bottom is a clean water chamber.The former hydroecium in top has water inlet, the bottom clean water chamber has delivery port, bottom half has base plate, base plate with 1.0-1.5% gradient sealing and fixing on wall box, the oil collecting pipe that lower floor water-oil separating unit is arranged on the lower sidewalls of base plate peak, on the sidewall of oil collecting pipe relative position, there is the sewage draining exit that discharges water of the band valve of water-oil separating unit the top of base plate minimum point, be superimposed together by flange and seal washer sealing between every adjacent two water-oil separating unit, on the casing of a water-oil separating unit of the oil water separator the superiors, an arch seal cover is arranged, the peak of seal cover has oil collecting pipe, the oil collecting pipe of each water-oil separating unit is connected in common excretory duct, common excretory duct is connected to the bottom of the oil catcher that is positioned at the oil water separator top, and the fuel outlet of band valve is arranged on the oil catcher.
The hydrophilic oil resistance filtering layer of water-oil separating unit is lined with silk screen by grid on the grid, be equipped with super hydrophilic oil resistance filter material on the silk screen and form.Super hydrophilic oil resistance filter material can different size or model, also can be by the compound use of super hydrophilic oil resistance filter material of two or more specifications and models.Hydrophilic oil resistance filtering layer also can be provided with plastic grill again on super hydrophilic oil resistance filter material, be lined with terylene silk net on the plastic grill, re-lays asphalt felt and constitute compound hydrophilic oil resistance filtering layer on terylene silk net.
In order on each water-oil separating unit of safety pressure relief safety valve to be arranged.
According to the needs that use, the use of can connecting of oil water separator of the present invention with hydrophilic oil resistance filtering layer that identical or different super hydrophilic oil resistance filter material forms or composite hydrophilic oil resistance filtering layer, oil water separator of the present invention can be the disclosed oil water separator use of connecting in " a kind of oil water separator " utility application of 99228119.9 at application number with the inventor also.
Oil water separator of the present invention is following running:
At first close the valve on the sewage draining exit that discharges water of each water-oil separating unit, open the valve of oil catcher fuel outlet, open water inlet then, to each water-oil separating unit water filling, after the oil catcher filling has water, close the valve of oil catcher fuel outlet, regulate water intake velocity, make that to go out water speed consistent with delivery port, former water is through the water-oil separating of hydrophilic oil resistance filtering layer, and the clean water chamber that clear water enters the water-oil separating unit is discharged and reclaimed, and oil droplet is gathered into bigger oil droplet come-up on hydrophilic oil resistance filter material, gather in the oil catcher through oil collecting pipe and conduit, gather the valve of opening fuel outlet behind the oil in the oil catcher, emit the oil of recovery.
Oil water separator of the present invention can not add any medicament and efficiently water-oil separating be reclaimed, it can be that the oil-containing water of 400mg/L is handled and to be reached below the 10mg/L with oil content, if what oil water separator series connection of the present invention is used, can make oil content drop to 0.3mg/L, meet the boiler feed water requirement.Another characteristics of oil water separator of the present invention are to handle the water yield can regulate with increase and decrease water-oil separating unit, and therefore easy to use, operating flexibility is big, and is economical and practical.
