Background technology

Oil exists with three kinds of states in water substantially, and the one, oil slick, it is to be present in the water than larger particles, utilizes severe poor, is easy to separate from water; The 2nd, oil in water emulsion, it is suspended in the water with smaller particles, is difficult to they are separated with general oil removal method; The 3rd, dissolving oil is separated their relatively difficulty, not emphasis of handling as oil-water separation system with the general physical method.Need solve to such an extent that be that the oil in water emulsion in the water is decomposed to come out efficiently from the water oil solution at present.

The oil in water emulsion separate mode roughly has heating, high voltage electric breakdown of emulsion, emulsion splitter breakdown of emulsion, membrane technique breakdown of emulsion, coalescence material absorption breakdown of emulsion, air supporting breakdown of emulsion and ultrasonic wave breast mode at present.Wherein, decompose by type of heating emulsification, if take electrically heated to require the expenditure of energy; If use steam heating, solidify phenomenon when oil product takes place the oil gas that evaporates for a long time easily.High voltage electric breakdown of emulsion mode is not suitable for boats and ships, lacks high-voltage power supply on the boats and ships, and is a kind of safe hidden danger.What emulsion splitter breakdown of emulsion mode adopted is chemical agent, causes secondary pollution easily.Air supporting breakdown of emulsion mode needs source of the gas, and separation efficiency is not very high.The method of membrane technique breakdown of emulsion can pollute on the film surface, reduces the through-current capability of film.Must correctly grasp vibrational frequency when ultrasonic dehydration uses, not only otherwise oil in water emulsion can not separate and emulsification aggravation.Reasonable manner is to adopt the method for coalescence material absorption breakdown of emulsion, uses special coalescence material, less elaioleucite and be agglomerated into oarse-grained oil droplet in the planar water oil mixing liquid.This method safety, reliable, economic.

Protecting the marine environment is subjected to the extensive concern of various circles of society, prevents that boats and ships from polluting is a major challenge that faces at present.Domestic refuse and oily water are the main sources that boats and ships pollute. pollute also at boats and ships artificial oily water in service and often take place.In order to reduce the pollution of oily water effectively to the ocean, International Maritime Organizaton requires tonnage greater than the boats and ships of 400T oily-water seperating equipment must be installed, and must satisfy the latest requirement of up-to-date IMO Resolution MEPC107 (49) number resolution to the bunker oil water separating system.Though existing various oily-water seperating equipment technology has carried out separating preferably to profit, generally all only limit to separate the greasy dirt of big grain.As the described oily-water seperating equipment of the patent No.: CN02149334.0,, can separate less greasy dirt though adopted coalescer, but because coalescer is installed in the secondary chamber, both also inconvenience replacing was cleaned in inconvenience, and the state if coalescer absorption reaches capacity will perform practically no function.And it still is powerless for littler oil droplet.

Summary of the invention

The purpose of this utility model is the defective that solves on the existing oily water separation technique, discloses a kind of bunker oil water separation device, and the utility model is to satisfy the bunker oil water separation device that MEPC107 (49) resolution requires, and is applicable to all types of navigating ships.

The utility model is achieved in that a kind of bunker oil water separation device, comprises gravity separation chamber, coalescer and slop oil tank, it is characterized in that: described gravity separation chamber is provided with the one-level gravity separation chamber and the secondary gravity separation chamber of serial connection successively; Described one-level gravity separation chamber and secondary gravity separation chamber are respectively equipped with import, oil discharge outlet and discharge outlet; Between the import in the discharge outlet in described one-level gravity separation chamber and secondary gravity separation chamber, be provided with coalescer; Described secondary gravity separation chamber discharge outlet also connects the strainer that filter core is housed.Described strainer is provided with the grade one filter and the secondary filter of serial connection successively.The output terminal of described strainer also is connected in series the oil content instrument of differentiating oil content concentration.Described oil content instrument connects two discharge tubes, but one has installed discharge solenoid valve, and another installs the magnetic valve that the treating water that will exceed standard is disposed to the bilge.Described coalescer also connects fresh water and irritates; Described oil content instrument is also irritated with fresh water and is connected in series.

What the utility model adopted is the two-stage filtration separate mode, earlier oarse-grained oil droplet in the water-oil mixture body is separated by action of gravity in the gravity separation chamber, carry out cascade filtration by strainer again and separate, with the oil in water emulsion separation of the molecule in the oil solution.After the coalescer that the utility model will have a small oil droplet adsorption function is arranged on one-level gravity separation chamber, and connects fresh water and irritate, realize making its regeneration, reduction, solved the problem that coalescer reaches capacity and can not adsorb behind the state again by hydraulic pressure.Under the effect of coalescer, be not agglomerated into big grain oil droplet by the small particle oil droplet of gravity separation, in secondary gravity separation chamber, carry out gravity separation again, and then carry out cascade filtration again by grade one filter and secondary filter and separate.

The beneficial effects of the utility model are: the coalescer that autoregeneration is set, slowed down the adsorptive pressure of filter core in the strainer, prolong the work-ing life of strainer, reduced the replacing number of times of terminal filter core, also reduced the secondary pollution that the filter core under changing causes simultaneously.The utility model can effectively be handled to the remaining residual oil of the various oil fuel that can carry on the boats and ships, very high density and by the emulsion blends of configurations such as ferric oxide, tensio-active agent.
