The oil skimmer (2) has a structure as follows: the elongated oil skimmer is made of materials capable of floating on a water surface, wherein an oil sucking inlet is formed on the right side of the oil skimmer in a length direction of the oil skimmer; the cross section of the bottom surface of the oil sucking inlet slants in a left high and right low manner; and a slant angle is from 45 degrees to 60 degrees. The oil skimming device has the advantages of ingenious concept, simple structure and convenience in use. The oil skimming device can automatically carry out an oil-water separation on industrial wastewater containing the oil, and has the beneficial effects of high oil-water separation efficiency, good oil-water separation quality and low oil-water separation cost. In addition, the oil skimming device is not powered.
Description
Technical field
The utility model relates to a kind of corollary apparatus of chemical industry equipment, specifically a kind of skimming plant of automatic collection waste oil.
Background technology
The oil-containing industrial water source is very wide, wherein mainly contains the oil plant oily waste water of petroleum industry, the oil-washing tank oily waste water of railway locomotive depot, the oily cargo ship oily waste water of scrapping yard, the emulsifiable oil waste water of machine cut processing and the oily waste water of coal chemical industry enterprises etc.For the processing of oil-containing industrial water, at first be to carry out water-oil separating, following method is adopted in water-oil separating usually:
1, floating method: be mainly used in the advanced processes of oil interceptor water outlet, remove tiny oil droplets and oil emulsion.After the come-up processing, the water outlet oil content can be down to 30 mg/litre.Its method is: an amount of air is passed in the oily waste water, form many micro-bubbles, consist of water, gas, oil droplet three-phase heterodisperse system under bubble.Under the poor effect of interfacial tension, bubble floating power and hydrostatic pressure, form gas-oil droplet combination come-up and realize water-oil separating.Floating method is pressed the method for Bubble formation, can be divided into three kinds of gas distribution floating method, molten gas floating method and electrolysis floating methods.
2, gas distribution floating method: this method mainly is will sneak into bubble breaking in the water by means of mechanical shearing, or enters waste water after air is dispersed into first tiny bubble, carries out the mixing wastewater with air come-up.Common method has impeller floating method, jet floating method and porous material aeration floating method, such as diffuser plate, microporous pipe, canvas duct etc.The advantage of gas distribution floating method is that equipment is simple, convenient management, and power consumption is lower.Shortcoming is that bubble breaking is thinless, generally is not less than 1000 microns, come-up effect thereby be restricted.In addition, adopt porous material aeration floating method, porous material stops up easily, the impact operation.
3, molten gas floating method: be bubbing from the waste water that contains supersaturated air, produce bubble to realize come-up.Commonly used have dissolved air flotation method and a vacuum floating method, and the former uses more general.The dissolved air flotation method is with water pump waste water to be sent into dissolving to be pressurized to 3～5.5 kilograms/centimetres 2, injects simultaneously air and makes it be dissolved in waste water under pressure.General dissolved air time is 2～4 minutes.Then waste water enters upper floating tank by pressure-reducing valve.
4, electrolysis floating method: utilize the electrolytic oxidation reduction effect of electric energy in oily waste water, and the Float upward function of the micro-bubble that produces at electrode thus purifies oily waste water.As adopt the soluble anode material, electrolysis coagulation can also occur simultaneously to be done in order to purify liquid waste.
5, Coagulation Method: available aluminium salt or molysite are made coagulant, and structures can adopt accelerating purifying pool, and treatment effect and floating method are basic identical.
When adopting floating method, also dosing coagulant often is to improve clean-up effect.
6, filtration method: the advanced processes means of Chang Zuowei floating method water outlet.The waste water processed of method after filtration, oil content can be down to below 10 mg/litre.Process structures and can adopt conventional rapid filter or pressure filter.But Comparison of Management is difficult, needs air recoil, the hot water backwash.Such as mismanagement, filtrate stops up easily.
7, bioanalysis: oil content below 30 mg/litre, and when containing the biodegradable harmful substance of other needs, just consider to use, generally just for oil removing.The oily waste water of petroleum refining factory after the Physical oil removing, just possesses the condition of processing with bioanalysis.
8, chemical method: chemical method is mainly for the treatment of the oil emulsion in a part of colloid and the dissolved matter, particularly oily waste water can not be separately in the waste water removed with Physical or bioanalysis.Comprise coagulating sedimentation, chemical conversion and neutralisation.
9, physical-chemical process: the oilfield sewage materialization treatment process generally includes two kinds of By Bubble-floating Method and absorption methods.
By Bubble-floating Method be with air with in the micro-bubble form injected water, micro-bubble and the elaioleucite that suspends in water are adhered to, because its density floats less than water, form scum layer and from water, separate.Often add flotation agent and improve flotation effect, flotation agent has demulsification and barbotage on the one hand, also has on the other hand the adsorption bridging effect, and the colloidal polyurea particle collection is floated with bubble.
Usually when adopting above method to process oily waste water, at first carry out the preliminary treatment of waste water, the oil that soon can directly remove is cleared up, and the method for mainly taking at present is artificial salvaging, manually salvage efficient low, salvage of poor qualityly, it is high to salvage cost.
Summary of the invention
The purpose of this utility model is the weak point that exists for prior art, proposes the technical scheme for a kind of skimming plant of automatic collection waste oil.This device can separate the oil in the oil-containing industrial water easily automatically.
The technical solution of the utility model is: a kind of skimming plant of automatic collection waste oil, comprise oil skimmer and salvage sump, it is characterized in that, oil skimmer is connected to collecting box by flexible pipe, and the structure of oil skimmer is to make the strip oil skimmer by the material of floatability on the water surface, have inlet port on the oil skimmer right side, inlet port arranges along the oil skimmer length direction, and the cross section of inlet port bottom surface is right low left high, inclination angle a=45-60 degree.
Described inlet port lowest part is apart from the height H of oil skimmer bottom surface=1-5 millimeter.
Described oil skimmer is made of plastics.
Described collecting box top is lower than the liquid level of salvage sump.
The utility model is to utilize oil ratio water light, oil float is in the characteristic of the water surface, make oil skimmer with the material of floatability on the water surface, have inlet port at oil skimmer, the inlet port cross section is right low left high, the porch that is inlet port is low, the exit is high, and oil skimmer is placed in the oily waste water, and oil skimmer will float over the waste water surface, because oil ratio water is clear, the collecting box position is lower than the salvage sump liquid level, utilizes siphon principle, and the oil of keeping afloat will enter from inlet port automatically, and flow to collecting box along flexible pipe, realized that the oil in the oil-containing industrial water separates automatically.The inlet port lowest part can guarantee that apart from the height H of oil skimmer bottom surface water can not enter inlet port when the water surface slight fluctuations, and the inclined plane of inlet port bottom surface also is to prevent that waste water from entering oil header.The utility model is skillfully constructed, simple in structure, easy to use, can automatically carry out water-oil separating to oil-containing industrial water, water-oil separating efficient is high, disintegrate-quality is good, separation costs is low, this device does not need power.
