The device for regenerating and processing of waste lubricating oil
Technical field
The invention belongs to the device for regenerating and processing that makes device for regenerating and processing waste lubrication oil, particularly waste lubricating oil that useless machine oil recycled.
Background technology
Owing to reasons such as lubricating oil oxidation in use, cracking and condensation cause the part component rotten, sneak into some impurity (as the metallic particles of dust, light oil, wearing and tearing etc.) simultaneously from the external world, and portions additive is destroyed.When rotten composition and impurities accumulation to a certain degree the time, lubricating oil just can not continue to use again, becomes waste lubricating oil.
What the process for regeneration of waste lubricating oil that adopts in the many waste oil regenerations manufacturer of China adopted all is acid/native method of reproduction, passes through sulfuric acid washing-clay-treated method and carries out waste lubricant oil regeneration.Because acid/local method causes the appearance of a large amount of acid sludges with the sulfuric acid scrubbing meeting, causes the pollution to environment.Waste lubricating oil distillation circular heating, making heat carrier and heat carrier circulating pump must be to possess the heat resistance of bearing temperature more than 450 ℃, the heating-up temperature height, disengagement area is little, and power consumption is high, easily cracking.
Also having a kind of waste lubricant oil regeneration technology is moisture, gas and the mechanical admixture that utilizes in the vacuum oil-filter removal waste lubricating oil.But this vacuum oil-filter is applicable to the in-line purification of machine oil, but medium-to-high grade I. C. engine oil, engine oil and some impurity oil big to viscosity, impure complicated component then can't filter, and often cause vacuum filter plugged filter and Impurity removal not thorough.
Summary of the invention
The object of the present invention is to provide a kind of device for regenerating and processing of waste lubricating oil, can realize the waste lubricating oil heated at constant temperature, increase the disengagement area of lubricating oil, make the disposable evaporation of waste lubricating oil on the evaporating surface, avoided the hydronic drawback of waste lubricating oil, heat time heating time is short, energy savings, reduced the cracking of waste lubricating oil, and, improved the quality of reclaimed oil the Impurity removal in the waste lubricating oil.
The object of the present invention is achieved like this: a kind of device for regenerating and processing of waste lubricating oil, constitute evaporimeter by shell and inner bag with sealing heating interlayer, its inner bag is the closure casing that top has the combination revolution bodily form of connector, on the connector of inner bag, adorning rectifying column by flange, top and bottom at the evaporimeter heating interlayer are being provided with oil-in and oil-out respectively, by sealed bearing the central rotating shaft that the upper end has fuel feed hole is installed in evaporimeter inner bag bottom centre, the petroleum pipeline end that is provided with above in evaporimeter is installed with sealed bearing, match with sealed bearing in the upper end of central rotating shaft, the oil-out of base of evaporator is connecting petroleum pipeline, the bracket end that has pipeline by symmetry on central rotating shaft is installed with the scraper plate that matches with the inner bag inwall respectively, the oil circuit of central rotating shaft fuel feed hole is communicated with the injector that is installed in scraper plate top by the pipeline on the support, bottom at evaporimeter is installed with heater, at the bottom of the evaporimeter person's of setting slag-drip opening, motor drives central rotating shaft by decelerator and rotates.
It is such utilizing the course of work of processing unit (plant) regeneration processing waste lubricating oil of the present invention: the waste lubricating oil through the heating furnace heating is delivered to evaporimeter by pressure, heated waste lubricating oil enters the heating interlayer from the oil-in of evaporimeter, hot waste lubricating oil in the further heating fumigators heating interlayer of the heater of base of evaporator, make the hot lubricating oil in the heating interlayer keep comparatively constant heating-up temperature, with the inner bag of heating fumigators as heat carrier.The motor drives central rotating shaft rotates, support on the central rotating shaft drives scraper plate and does gyration along the circumferential wall of inner bag and the bottom surface of the bottom of a pan shape, and the oil-out of evaporimeter heating interlayer bottom is ejected into the hot lubricating oil in the evaporimeter heating interlayer on the inner bag face of evaporimeter by injector through the fuel feed hole of central rotating shaft, oil pipe on the support equably by petroleum pipeline.Central rotating shaft drives scraper plate and does gyration along the bottom surface of inner bag circumferential wall and the bottom of a pan shape, make injector be ejected into used heat lubricating oil on the inner bag face by scraper plate to spread to oil film at the uniform velocity equably, to satisfy the needs of disengagement area less than 0.5mm thickness.Because the hot waste lubricating oil in the evaporimeter heating interlayer, has guaranteed the inner bag of the waste lubricating oil of heating in the evaporimeter heating interlayer with the stationary temperature heating fumigators by the heater heat temperature raising of evaporimeter bottom.The utility model has been created evaporation conditions at a lower temperature, owing to guarantee uniform all the time the heated oil film less than 0.5mm thickness on the inner bag, makes the disengagement area maximization.Can make waste lubricating oil guarantee to distill under the temperature required prerequisite according to the test fuel film vaporization, required high-temperature temperature has reduced by 100 degrees centigrade than the required temperature of conventional distillation, and the hot oil outlet temperature that adds of heating furnace is to get final product about 400 ℃.The time of evaporation also became disposable evaporation by former circulation intensification-evaporation, the waste lubricating oil that serves as heat carrier in the evaporimeter heating interlayer need not to return the heating that circulates in the heating furnace, does not also need anti-high temperature heat-resistant carrier circulating pump more than 450 ℃ simultaneously.Significantly reduce the time of evaporation, reduced the cracking that causes waste lubricating oil because of long high temperature evaporation.After the waste lubricating oil composition is evaporated, carries out classification by the rectifying column of installing on the evaporimeter inner bag connector and reclaim, can obtain regenerate base oil and light oil.After the waste lubricating oil evaporation, the impurity of generation is discharged from the slag-drip opening that base of evaporator is provided with in the evaporimeter inner bag.Device for regenerating and processing waste lubrication oil of the present invention has been realized heated at constant temperature to waste lubricating oil, increased the disengagement area of lubricating oil, make the disposable evaporation of waste lubricating oil on the evaporating surface, avoided the hydronic drawback of waste lubricating oil, warm-up time is short, and energy savings has reduced the cracking of waste lubricating oil, and, improved the quality of reclaimed oil with the Impurity removal in the waste lubricating oil.The combustion gas that heater burnt is the flammable light gas that discharge at the rectifying column top, has therefore also just solved the gas emission problem.
