Description
Technical field
The utility model relates to the apparatus field of the waste oil regeneration technology of technical oils, relates in particular to a kind of regeneration system rapidly that can waste oil treatment be become qualified absolute oil.
Background technology
Along with fast development of national economy, China's machinery industry has also obtained significant progress, causes the quantity discharged of waste oil to increase.Waste oil can pollute environment with SO2 and the CO2 that burning disposal produces as Hazardous wastes, and the processing of waste oil has been become our problem demanding prompt solution.Therefore, State Environmental Protection Administration classifies waste oil as 21 century at one of three big emphasis of environmental protection field major control.Machine oil is the high value added product that is come out by petroleum refining, and along with the shortage of petroleum resources, the supply and demand of machine oil also goes wrong, and the regenerating waste oil technology also has important meaning to save energy.The generation of energy problem also makes the price of machine oil improve, and the regenerating waste oil technology can produce good economic benefits.
Technical oils (like the oil engine wet goods) is behind life-time service, and the existence because of undesirable substances such as carbon granule, mechanical impurity, deep oxidation thing, colloid, pitches makes oily emulsification, blackout, need make oil reach requirement through regeneration.The waste oil regeneration machine is a technical oils regenerated specific equipment, has been widely used in the waste oil regeneration field.Existing waste oil regeneration machine mainly comprises stirring tank, powder filling apparatus, vacuum pump, residual sea water pump, hot oil pump, strainer, oil inlet pipe, oil outlet pipe, escape pipe and valve etc., therebetween through handling pipe connection.After pending waste oil through in stirring tank and being heated to certain temperature; Using powder filling apparatus interpolation powder additive flocculates, adsorbs waste oil; Thereby remove undesirable substances such as carbon granule that is dispersed in the oil, mechanical impurity, deep oxidation thing, colloid, pitch,, make the color restoration clear of oil again through the press filtration of strainer; Each item performance index of waste oil such as reduction oil engine make it become qualified absolute oil.Absolute oil after the regeneration is got rid of through oil outlet pipe.
Through retrieval, there has been the device of comparatively advanced regenerating waste oil at present, like Chinese patent; Announced that notification number is " waste oil regeneration oil filter system " patent of CN201300008 on October 31st, 2008, just disclose a kind of waste oil regeneration system; It comprises reactor drum, pressure filter, heat-conducting oil heating circulation device, wherein, directly gets into reactor drum after the coarse filtration of waste oil process oil-feed valve; Flocculation agent and sorbent material are added in respectively in the reactor drum, waste oil is flocculated, adsorbs, but because in the waste oil; Can form certain dirt after adding flocculation agent, the dirt that flocculates can stop up and fill up by rapid hole with sorbent material, thereby influences adsorption effect; Simultaneously, because pressure filter is connected with the oil outlet pipe of reactor bottom, the dirt that flocculates can all accumulate on the filter press filter board; Also cause obstruction easily to filter press filter board, so, in use need the frequent change filter plate; Lose time, increased trouble; In addition, in the technique scheme, the control of the amount of amount, flocculation agent and the sorbent material of waste oil is not had to adopt the charging system of control automatically, reinforced what mainly by the people for controlling, can not accomplish accurately to annotate by the requirement of filling a prescription; Moreover; In technique scheme, owing to just behind pressure filter, be provided with vacuum separator, waste oil does not carry out vacuum hydro-extraction before flocculation reaction and absorption reaction handles; And moisture is bigger to the flocculation adsorption effect influence of flocculation agent, sorbent material; So, in the technique scheme, relatively poor to the effect that contains after the big waste oil treatment of moisture.
