Description

A kind of multistage high accuracy oily-water seperating equipment
Technical field
The present invention relates to oily water separation technique field, especially relate to a kind of for coal liquifaction F-T synthesis water, coal gasification The multistage high accuracy oil of the oil-polluted waters such as sewage, semi-coke sewage, oil shale sewage, oil-contaminated water of oil field, machining oil-polluted water Water separation device.
Background technology
Oil-polluted water is a kind of common industrial wastewater, and along with developing rapidly of national economy, oil exploitation, oil add The oily waste water water yield that all conglomeraties such as work, machining produce also gets more and more.And the harm that environment is caused by oily waste water is also Increasing, the harm of oil-polluted water is mainly manifested in the following aspects: 1. affect drinking water sources and groundwater resources, danger Evil aquatic resources;2. it is detrimental to health;3. atmosphere pollution;4. production estimation is affected;5. destroy natural landscape, even also have Probably due to the oil product of coalescence burns and produces safety problem.
Oil-water separation is the tap of the follow-up water treatment technology of oil-polluted water, the removal of oil-water separation particularly oil emulsion and point From, it is one of emphasis and difficult point, oil-water separation will directly affect the operation result of whole water treatment system.Oil emulsion is grain Degree is the superfine oil droplet of 0.1~10 μm, owing to oil-water interface has the existence of surfactant, generally steady with oil-in-water form Surely being dispersed in water, separating difficulty is relatively big, and the removal effect of oil emulsion is managed by tradition by the degreasing technique of oil-polluted water not to the utmost Thinking, also needing often to be aided with the leading breakdown of emulsion processes such as electrolytic flocculation, its energy consumption and material consumption are bigger.
And the oil-water separation precision of the most commonly used oily water separating equipment is low, easily block, improper complicated component Oil-polluted water, therefore hinders the development of industrialized production.
In sum, a kind of oil-water separation precision being presently required high, cost performance is high, it is possible to adaptive element complicated containing greasy dirt Water, can industrially scalable use oily-water seperating equipment.
Summary of the invention
The present invention is to solve the problems referred to above existing for the oily-water seperating equipment of prior art, it is provided that a kind of structure Rationally, floor space is little, easy to operate, and operating cost is low, applied widely, and continuous processing amount is big, oil-water separation precision and effect Rate is high, the one multistage high accuracy oily-water seperating equipment of good separating effect.
To achieve these goals, the present invention is by the following technical solutions:
The one multistage high accuracy oily-water seperating equipment of the present invention, including tank body, described tank body top is provided with light oil oil extraction Mouthful and backwash air inlet, be provided with dividing plate in described tank body, tank body is separated into upper and lower two spaces by described dividing plate, upper and lower two Space forms the first Disengagement zone and the second Disengagement zone respectively, is provided with gap between dividing plate and inner tank wall, and this gap is formed and Mouthful, longitudinally spaced in described first Disengagement zone it being provided with at least two independent oil-water separation unit, tank body side is provided with into water Mouthful, described oil-water separation unit is connected with water inlet, is provided with longitudinal baffle, between longitudinal baffle and dividing plate in described second Disengagement zone Being provided with gap, this gap forms overfall, and the second Disengagement zone is separated into oil collecting zone and gathering ground by longitudinal baffle, described oil collecting zone Bottom is provided with heavy oil oil drain out and sewage draining exit, and the bottom of described gathering ground is provided with outlet.Tank body is isolated by median septum of the present invention Becoming two separate space, wherein the first Disengagement zone is substantially carried out flash trapping stage, is used for separating light oil, and the second Disengagement zone carries out two grades Separate, for heavy oil separation and water, separating effect can be greatly improved through the second-order separation, the present invention the first Disengagement zone at least provided with Two independent oil-water separation unit, to improve treating capacity, utilize pure physical separation by the oil in oil-polluted water, particularly emulsifying Oil is removed, is reclaimed, and oil-polluted water enters inlet water divider from water inlet, and oil-polluted water is introduced columnar water and separates by inlet water divider In filter element, in water body, oil emulsion separates after the fibrous membrane on filter element contacts with columnar water, special at fiber film material microcosmic and surface Property effect under, oil emulsion progressively breakdown of emulsion, formed tiny oil droplets, when tiny oil droplets penetrates fibrous membrane, be progressively gathered into bigger oil Drip, after larger oil droplet departs from fibrous membrane, float under gravity or separation of sinking, thus realize oil-water separation, separation accuracy Height, the light oil at top floats up to the light oil oil drain out discharge collection after tank body top is assembled through tank body top, and density overweights gently The water of oil and heavy oil enter the second Disengagement zone through sedimentation mouth the most under gravity and are further carried out separating;Longitudinal baffle is by second Disengagement zone is separated into oil collecting zone and gathering ground, owing to heavy oil density is more than water, under the dividing plate stop with longitudinal baffle, is positioned at upper strata Water be collected to gathering ground through overfall overflow, heavy oil then rests on oil collecting zone, so that heavy oil and water efficiently separate Separating, be practically free of heavy oil in last water, separating effect is the best, is finally collected at the heavy oil of oil collecting zone through heavy oil oil drain out Discharge is collected, and the waste water of gathering ground is discharged through outlet.Light oil and the heavy oil collected after being processed by the present invention are contained The water yield is the lowest, can produce again economic benefit as sale of finished goods or reprocessing while reaching environmental protection purpose, and waste water Middle oil content is extremely low, is conducive to carrying out follow-up water process;Compressed air is used can column water to be separated by backwash air inlet Filter element carries out backwash, can
