Description
Technical field
This utility model is related to waste process field, more particularly to a kind of waste lubricating oil comprehensive recycling device.
Background technology
Lubricating oil is used in all kinds automobile, plant equipment reducing the liquid of friction, protection machinery and workpiece
Or semisolid lubricants, act primarily as the effect such as lubrication, cooling, antirust, cleaning, sealing and buffering
Due to high temperature, air oxidation during use, gradually aged deterioration, along with mechanical part rubs sassafras lubricating oil
The metal dust of generation, from the environment into moisture, impurity etc., cause the pollution such as mineral oil, oxidation, therefore, waste lubricating oil
In in addition to C, H etc., can also contain a small amount of other elements, the element such as including Fe, Mg, Ca, Zn, Cu, Sn, Al and Ni.Wherein,
Fe, Cu, Al and Ni belong to Wear metal；Si, B and Na can be summarized as pollution element, and such as Si is due to air filter
The dust foul of imprecision suction comes from defoamer in oil, and B and Na is mixed into due to the leakage of engine-cooling system
Antifreezing agent, and Mg, Ca, Zn and Mo be additive element.
The method that mineral waste lubrication recovery of oil is adopted has：High-temperature cracking method, acid-hargil method, way of distillation etc..Wherein, high temperature
Cracking process be by temperature and pressure effect realizing cracking of oil, thermal cracking is exactly the macromole for making one class of diesel oil using high temperature
Hydrocarbon, decomposes cracking become the small molecule hydrocarbon of one class of gasoline, and under cracking conditions, hydro carbons is mainly decomposed and condensation two
Class is reacted；Used oil thermal cracking product mainly has cracked gas, gasoline, diesel oil and residual oil etc.；Thermal cracking yield is higher, but energy consumption
Height, contains more unsaturated hydrocarbons in product, stability is bad；Meanwhile, the condensation reaction occurred during Pintsch process can make
Coke heavy in the pipeline of heating furnace, does not adopt Pintsch process in waste oil regeneration technology substantially.Acid-hargil method is to use concentrated sulphuric acid
React with the undesirable constituentss in oil, generate acid sludge, after precipitation with separating of oil, now, oil then is used at hargil in acidity
Reason, so that it may obtain that acid number is little, the oil product of good security；But after using sulphuric acid, oily hair life in part is esterified, and it is low that waste oil reclaims yield；
The acid waste residue of by-product and other side-products, cause secondary pollution, according to《Waste lubricating oil recycles pollution control technology rule
Model》(HJ607-2011), forbid at present being continuing with sulphuric acid/hargil method regeneration waste lubricating oil.
High temperature distillation method is different using Organic substance boiling point, and material is separated, and the technology is simple and reliable.Waste oil is heated,
Lower boiling Organic substance is first distilled from tower top, and high boiling point stays in bottom.
Utility model content
The purpose of this utility model is that the purpose of this utility model is to research and develop a kind of process is simple, safety can
Lean on, small investment, a kind of strong waste lubricating oil comprehensive recycling device of device motility.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of waste lubricating oil is comprehensively returned
Receipts utilize device, and breakdown of emulsion Sedimentation tank that described device includes being sequentially connected, preheater, distillation column, condenser, after the condenser
Light-weight fuel oil collection device and absorbent charcoal adsorber is connected to, wherein, in the breakdown of emulsion Sedimentation tank, stirring is provided with
Waste oil is delivered to the preheater by pump by device, the breakdown of emulsion Sedimentation tank, and waste oil passes through feeding after preheater preheating
It is pumped in distillation column, the bottom of the distillation column is provided with residual oil outlet.
Specifically, the bottom of the breakdown of emulsion Sedimentation tank is provided with waste water and dregs of fat discharger.
Technology of the processing meanss of waste lubricating oil of the present utility model using the high-temperature pressure-reduction way of distillation.In due to waste lubricating oil
Containing a small amount of impurity and moisture, waste lubricating oil need to be carried out pretreatment, waste lubricating oil is transported to by breakdown of emulsion Sedimentation tank by pump
In (Sedimentation tank is using covered and enclosed process), and add a certain amount of demulsifier (nonionic surfactant, Propylene Glycol polyoxy
Ethylene polyethenoxy ether) carry out breakdown of emulsion.Breakdown of emulsion mainly replaces emulsifying agent of the absorption on oil-water interfaces by adding demulsifier,
Reduce the elasticity and stickiness of interfacial film, so as to reduce interfacial film strength, accelerate the coalescence of drop, separate profit.Breakdown of emulsion
It is 3.5kg that agent addition is waste lubricating oil demulsifier addition per ton.For preferably reaching the effect of breakdown of emulsion, during breakdown of emulsion
It is stirred so that in oil product, each molecular motion acutely, with good mobility, reaches more preferable demulsification.Breakdown of emulsion is stirred
The time is mixed for 20～30 minutes, temperature is room temperature.After through breakdown of emulsion process, stirring system is turned off, oil product standing separation is made, due to
The density ratio water of oil product is little, through standing after, oil product is located at the upper strata of breakdown of emulsion Sedimentation tank, and water and other impurities are located at lower floor, through one
The standing of section time, then the water and impurity (dregs of fat S1) of bottom are discharged.The waste lubricating oil of oily waste water W1 and the dregs of fat is separated
Waste oil is delivered in preheater by pump, steam heating-up temperature is 90 DEG C, separates moisture content, is then pumped into distillating still through feeding
In, heating up, control tower top temperature is at 200～250 DEG C or so.Slow programming rate is kept, bumping is prevented, lower boiling Organic substance
First distill from tower top, condensed device condensation (about 20 DEG C of condensation temperature) is collected afterwards and obtains light-weight fuel oil, and condensation process is produced
Raw incoagulable gas (G1) is with being discharged by aiutage after activated carbon adsorption.When the fuel oil color for distilling gradually becomes
Deep, and after the residual oil outlet examination at random flash-point by distillation column bottom and viscosity, stop distillation, the remaining oil product in distillating still bottom is
For residual oil (S2), in residual oil based on heavy oil composition, also contain a small amount of colloid, asphaltene precipitation thing, with certain calorific value,
Belong to hazardous waste (HW11), otherwise processed.Meanwhile, fixed gas is processed using activated carbon adsorption.
In sum, waste lubricating oil comprehensive recycling device process is simple of the present utility model, safe and reliable, investment
Few, device motility is strong.
