Description
Technical field
The present invention relates to the deodorizing device that a kind of lubricating oil reclaims.
Background technology
Automobile oil is the requisite articles for use of automobile engine, and it has between minimizing piston and cylinder, and the wearing and tearing between main shaft and bearing shell, cool engine, prevent engine components corrosion, engine are carried out to the effects such as sealing.
In automobile use procedure, due to the friction etc. between each parts of engine, in lubricating oil, can impurity be participated in, thus in order to ensure the normal use of automobile, usually need to regularly replace lubricating oil, ensureing lubricant effect.And for waste lubricating oil, usually carry out recycling.
In the process that waste lubricating oil is reclaimed, need to add additive decontamination while to waste lubricating oil heating, then while heating, add decolourizing agent carry out discoloring reclaimed oil, but when heating waste lubricating oil, some impurity in waste lubricating oil can become gaseous state and be discharged, the impurity of these gaseous states is with frowziness usually, contaminated environment, thus needs to carry out taste removal process to the exhaust in Spent lube reclamation process.
Summary of the invention
The present invention be directed to problems of the prior art to propose, its object is to the deodorizing device providing a kind of lubricating oil purified the exhaust in Spent lube reclamation process to reclaim.
Following technical scheme is adopted for realizing object of the present invention.
The deodorizing device of the lubricating oil recovery of technical scheme 1, comprise emptying surge tank, caustic wash tower, alkali lye supplying tank, exhaust pump and NaOH solution circulating pump, condenser pipe is surrounded by the periphery of described emptying surge tank, the described entrance of emptying surge tank is connected with the blast pipe of re-refining oil unit, the outlet of described emptying surge tank is connected with the lower end of described caustic wash tower, the bottom of described emptying surge tank is connected with Oil residue recuperation bucket, the middle part of described caustic wash tower is provided with wire netting, be provided with above described wire netting and alkali lye can be sprayed for vaporific alkali lye shower nozzle, described alkali lye shower nozzle is connected with described alkali lye supplying tank, the upper end of described caustic wash tower is connected with described exhaust pump, the lower end of described caustic wash tower is connected with alkali lye supplying tank via described NaOH solution circulating pump.
The deodorizing device of the lubricating oil recovery of technical scheme 2, in the deodorizing device that the lubricating oil of technical scheme 1 reclaims, the lower end of described caustic wash tower is also connected with sewage disposal system via draining pump.
Compared with prior art, the present invention has following beneficial effect.
According to the deodorizing device that the lubricating oil of technical scheme 1 reclaims, it comprises emptying surge tank, caustic wash tower, alkali lye supplying tank, exhaust pump and NaOH solution circulating pump, the entrance of emptying surge tank is connected with the blast pipe of re-refining oil unit, the outlet of emptying surge tank is connected with the lower end of caustic wash tower, the bottom of emptying surge tank is connected with Oil residue recuperation bucket, the alkali lye shower nozzle of caustic wash tower is connected with alkali lye supplying tank, the upper end of caustic wash tower is connected with exhaust pump, and the lower end of caustic wash tower is connected with alkali lye supplying tank via NaOH solution circulating pump.
By the deodorizing device that such lubricating oil reclaims, exhaust from re-refining oil unit is introduced into emptying surge tank and is condensed, Oil residue recuperation bucket is recovered to containing oil content in exhaust, then exhaust enters caustic wash tower, via the wire netting being had alkali lye by spray, by taste removal, then discharged by exhaust pump, the alkali lye bottom caustic wash tower is delivered to alkali lye supplying tank by NaOH solution circulating pump and recycles.Thus can be reclaimed again the gaseous state in the exhaust of re-refining oil unit or mist state lubricating oil by emptying surge tank, and the smell of the gas produced in lubricant oil regeneration process is mostly acidic materials, the smell of exhaust effectively can be removed by caustic wash tower, and can repeatedly reclaim use alkali lye, reduce the cost of taste removal.
In addition, according to the deodorizing device that the lubricating oil of technical scheme 2 reclaims, the lower end of caustic wash tower is also connected with sewage disposal system via draining pump, when the alkali lye of discharging from alkali lye supplying tank recycles totally, deodorizing device can be made to stop, bottom caustic wash tower, discharge the alkali lye after using, inputted sewage disposal system, carry out process discharge, prevent sewage pollution environment.
Accompanying drawing explanation
Fig. 1 is the schematic diagram representing the deodorizing device that lubricating oil of the present invention reclaims.
Detailed description of the invention
Below, based on accompanying drawing, the deodorizing device that the lubricating oil as an example of the present invention reclaims is described.
Fig. 1 is the schematic diagram representing the deodorizing device that lubricating oil of the present invention reclaims.
As shown in Figure 1, the deodorizing device that lubricating oil of the present invention reclaims comprises emptying surge tank 10, caustic wash tower 20, alkali lye supplying tank 30, exhaust pump 40 and NaOH solution circulating pump 50.
Condenser pipe 11 is surrounded by the periphery of emptying surge tank 10, the entrance 12 of emptying surge tank 10 is connected with the blast pipe 60 of re-refining oil unit, the outlet 13 of emptying surge tank 10 is connected with the lower end of caustic wash tower 20, and the bottom of emptying surge tank 10 is connected with Oil residue recuperation bucket 70.
The middle part of caustic wash tower 20 is provided with wire netting 21, be provided with above wire netting 21 and alkali lye can be sprayed for vaporific alkali lye shower nozzle 22, alkali lye shower nozzle 22 is connected with alkali lye supplying tank 30, the upper end of caustic wash tower 20 is connected with exhaust pump 40, and the lower end of caustic wash tower 20 is connected with alkali lye supplying tank 30 via NaOH solution circulating pump 50.
According to the deodorizing device that above-mentioned lubricating oil reclaims, it comprises emptying surge tank, caustic wash tower, alkali lye supplying tank, exhaust pump and NaOH solution circulating pump, the entrance of emptying surge tank is connected with the blast pipe of re-refining oil unit, the outlet of emptying surge tank is connected with the lower end of caustic wash tower, the bottom of emptying surge tank is connected with Oil residue recuperation bucket, the alkali lye shower nozzle of caustic wash tower is connected with alkali lye supplying tank, the upper end of caustic wash tower is connected with exhaust pump, and the lower end of caustic wash tower is connected with alkali lye supplying tank via NaOH solution circulating pump.
