Abstract
The utility model discloses a filtering rotational flow separation device for removing impurities in waste lubricating oil. The filtering rotational flow separation device comprises a sedimentation filter, a static swirler, a dynamic swirler and a vacuum degassing tower. An oil outlet positioned at the top end of the sedimentation filter is communicated with an oil inlet positioned on a side wall of the static swirler through a pipe, an oil outlet positioned at the top end of the static swirler is communicated with an oil inlet positioned on a side wall of the dynamic swirler through a pipe, an oil outlet positioned on the upper portion of the dynamic swirler is communicated with an oil inlet positioned on a side wall of the vacuum degassing tower through a pipe, a bottom oil outlet of the vacuum degassing tower is connected with a degassing tower bottom pump, and an oil inlet positioned on a side wall of the sedimentation filter is connected with heater for heating the waste lubricating oil through a pipe. When the filtering rotational flow separation device is applied to distillation processing of the waste lubricating oil in a conventional reduced pressure distillation process, the continuous operation cycle of a reduced pressure distillation tower can be prolonged, and accordingly the yield of lubricating oil and tower top light oil is improved.
Description
Technical field
The utility model relates to a kind of for pretreatment unit before the waste lubricant oil regeneration underpressure distillation, specifically relates to the front filtration cyclone separation device of removing impurity in the waste lubricating oil of a kind of waste lubricant oil regeneration underpressure distillation.
Background technology
Gradually aged deterioration and replaced of the impact that lubricating oil in use is subject to environment, contain the imperfect components such as certain moisture content, iron filings, additive (have the needed lubricity of equipment for making lubricating oil, add artificially multiple property and be scattered in well compound in the lubricant base), acidic substance, greasy filth in the waste lubricating oil that these displacements are recovered.
At present, domestic some is to adopt reduced pressure distillation process on process for regeneration of waste lubricating oil, namely takes the conventional reduced pressure distillation process of refining of petroleum method.But one of topmost difference of processing of the processing of waste lubricating oil and oil is exactly to have added various additives in the waste lubricating oil, these additives are dispersed in the waste lubricating oil with the size (0.1-1um) of subsubmicron, high temperature action during underpressure distillation has destroyed portions additive (thermolysis, rotten), the additive particulate that these are destroyed just is deposited on column plate, on filler and the boiler tube, blocking channel impact operation has restricted the continuous cycle of operation (reason that filler stops up caused the continuous cycle of operation generally just to need device break-down maintenance and maintenance about 30-50 days) of the waste lubricant oil regeneration vacuum distillation apparatus that adopts conventional reduced pressure distillation process and the yield (yield of lube stock and cat head lightweight oil plant only has about 75%) of lube stock.
The utility model content
Thereby the technical problems to be solved in the utility model provides a kind of continuous cycle of operation that can prolong the vacuum still in the reduced pressure distillation process when adopting conventional reduced pressure distillation process distillation to process waste lubricating oil and improves the filtration cyclone separation device of impurity in the removal waste lubricating oil of lubricating oil and cat head lightweight oil plant yield.
For solving the problems of the technologies described above, a kind of filtration cyclone separation device of removing impurity in the waste lubricating oil of the utility model, comprise settlement filter, static swirler, dynamic cyclone device and vacuum degassing tower, the top oil outlet of described settlement filter is connected with the sidewall oil-in of described static swirler by pipeline, the top oil outlet of described static swirler is connected with the sidewall oil-in of described dynamic cyclone device by pipeline, the top oil outlet of described dynamic cyclone device is connected with the sidewall oil-in of described vacuum degassing tower by pipeline, the bottom oil outlet of this vacuum degassing tower is connected with degassed column bottoms pump, and the sidewall oil-in of described settlement filter is connected with the well heater that waste lubricating oil is heated by pipeline.
When the filtration cyclone separation device of impurity is applied to conventional reduced pressure distillation process in the removal waste lubricating oil that the employing said structure forms, at first by described well heater waste lubricating oil is heated, Heating temperature is to 250-300 ℃, make very big portions additive decomposes in the waste lubricating oil, rotten, a part becomes carbon granules and dust, and another part becomes settling, suspended substance or dope; Impurity and waste lubricating oil that these carbon granules, dust, settling, suspended substance or dope and lubricating oil produce in use and removal process together enter settlement filter, suspended substance in the waste lubricating oil and dope are filtered during by settlement filter top filler and are collected in the filler, and discharge larger particles and the settling bottom through being settled down to settlement filter; The effect of being stressed of the waste lubricating oil of settlement filter top oil outlet tangentially enters static swirler "conesep" section along static swirler, be subjected to the effect of eddy flow centrifugal force, waste lubricating oil is oppositely migrated to static swirler top oil outlet along static swirler cone center, granular deposit is thrown to the inwall of static swirler cone, sinks down into the afterbody outlet discharge of static swirler cone along the inwall of static swirler cone; The waste lubricating oil effect of being stressed of static swirler top oil outlet tangentially enters dynamic cyclone device "conesep" section along dynamic cyclone device, the centrifugal action that the high rotating speed eddy current that is subjected to the high speed rotating of dynamic cyclone device swiveling wheel and forms produces, waste lubricating oil is oppositely migrated to described dynamic cyclone device top oil outlet along dynamic cyclone device cone center, the subparticle settling is thrown to the inwall of dynamic cyclone device cone, sinks down into the afterbody outlet discharge of dynamic cyclone device cone along the inwall of dynamic cyclone device cone; The effect that the waste lubricating oil of dynamic cyclone device top oil outlet is stressed enters vacuum degassing tower, vacuum degassing tower carries out degassed to rotten gas and the light constituent in the waste lubricating oil that produces of additives decompose in the waste lubricating oil, vacuum outgas cat head oil gas removes pumped vacuum systems II, at the bottom of the vacuum degassing tower waste lubricating oil degassed by pump delivery at the bottom of the vacuum degassing tower to vacuum furnace heating, carry out underpressure distillation to vacuum still at last.The utility model can be removed various additives and the mechanical wear impurity of waste lubricating oil because in use producing in the waste lubricating oil, can avoid stopping up because of the mechanical wear impurity that in use produces because of additive and waste lubricating oil the filler of vacuum still, therefore the cycle of operation that can improve vacuum still in the reduced pressure distillation process, the yield of raising lube stock and cat head oil plant.
