Description
Technical field
What the present invention relates to is a kind of used oil cycling and reutilization treatment process and equipment thereof, and particularly a kind of being applicable to handled method and the equipment thereof that is reduced into cleaning machine oil with useless high-speed machine oil and useless regular engine oil.
Background technology
China's machine oil output accounts for 20 percent of petroleum products total amount, and annual consumption is more than 6,000,000 tons.It is widely used in car engine, variator, gear and worm gearing quench, lubricated etc., but be big machinery, boats and ships, or the employed machine oil of large and small automobile all clearly stipulated the oil draining period or the standard of changing oil (China be every month all must change once) both at home and abroad, its reason is machine oil oxygenizement owing to high temperature and air in the process of using, meeting aged deterioration gradually, add the metal-powder that grinds on the friction parts, respiration and other reason and enter moisture in the oil, not only polluted oil, but also can promote the oxidation of machine oil.So the color of machine oil deepens and produces impurity such as throw out, greasy filth, paint film and hard varnish film gradually.Directly cause the machine oil result of use obviously to descend, these electrodeposition substances cause the various faults of machine, and must change on the duct and purifier of the surface that rubs parts, machine oil circulation, it is big that China changed discarded useless machine oil quantity in annual every month, is surprising in fact.In each, about about 900 tons of total growing amount of the every month used oil in small city (used oil at general little county town every month growing amount about about 300 tons), this does not also comprise various depleted animal and vegetable oil, acidifying oil, sewer oil, useless heavy oil, waste lubricating oil therebetween.And the byproduct (tankage) that can utilize various places refinery, chemical plant, fertilizer plant, urea plant, coke-oven plant is as alcohols, sulphonated oil, petroleum naphtha, paraffin, benzene, naphthalene, ketone etc., all can be converted into fuel oil, its enormous amount, cheap, purchase easily.The waste oil that China every year is so a large amount of is not owing to there is rational treatment process at present, but by toppling over, burning solves, and this is not only to have caused huge energy dissipation, and has formed serious ecological pollution, is threatening human environment of depending on for existence.With the rational art breading of all kinds of used oil processes; after removing rotten composition and external contaminant, reduction becomes lubricating oil, no matter utilizes or the environment protection aspect from Energy resources again; still can all be very suitable selection for the producer brings huge economic benefit angle.
Summary of the invention
The present invention is directed to above-mentioned weak point a kind of used oil cycling and reutilization treatment process and equipment thereof are provided, the waste oil in the waste oil groove is transported in oil strainer and the trash eliminator, tentatively filter by extracting pump.Waste oil after then will tentatively filtering is heated to 40～90 ℃, is squeezed into by force (forcing) pump and carries out secondary filter in the ceramic membrane filter device, separates all kinds of impurity, produces clean lubricating oil.
Used oil cycling and reutilization treatment process of the present invention and equipment thereof take following scheme to realize: used oil cycling and reutilization equipment comprises the waste oil groove, extracts pump, oil strainer, trash eliminator, force (forcing) pump and ceramic membrane filter device; The extraction pump is installed on the waste oil trough rim, in the import of extracting pump filtering head is installed, filtering head sinks in the waste oil groove, extracting pump outlet links to each other with oil strainer, oil strainer is communicated with by pipeline with trash eliminator, the trash eliminator bottom is equipped with bleed valve, and the import of force (forcing) pump is connected with trash eliminator, and the pressurization pump outlet links to each other with the ceramic membrane filter device.
