Description

The regenerator for waste lubricating oil exhaust treatment system
Technical field
The utility model relates to a kind of regenerator for waste lubricating oil exhaust treatment system.
Background technology
The regenerator for waste lubricating oil Distallation systm can produce the small part fixed gas in process of production, because its gas flow is very little, be difficult to recycle, and generally it is that end at the vacuum unit directly enters atmosphere.Because the composition very complex in the waste lubricating oil, mainly be the various impurity of sneaking in various additives, auxiliary agent and the use procedure, in the process when temperature is heated to more than 200 ℃, there are portions additive, auxiliary agent and impurity can decompose the gas that generation is difficult for condensation on a small quantity, assemble at the fractionating column top, under the effect of vavuum pump, finally enter atmosphere.Although this part gas amount is little, smell is very unpleasant, and the ambient atmosphere environment is caused certain pollution, directly affects worker and peripheral village resident's normal operation and life, and therefore, this part tail gas must thoroughly be processed.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of defects that solved is provided, can thoroughly process the tail gas that the regenerator for waste lubricating oil Distallation systm produces in process of production, avoid the regenerator for waste lubricating oil exhaust treatment system of environmental pollution.
The technical scheme that its technical problem that solves the utility model adopts is: described regenerator for waste lubricating oil exhaust treatment system, comprise feedstock oil drying tower vacuum condenser, lightness-removing column vacuum condenser and molecular clock tower vacuum condenser, it is characterized in that: feedstock oil drying tower vacuum condenser, the tail gas outlet of lightness-removing column vacuum condenser and molecular clock tower vacuum condenser is connected with the tail gas concetrated pipe respectively, the tail gas concetrated pipe is connected to the bottom of caustic wash tower, the middle part of caustic wash tower is provided with packing layer, top is provided with the alkali lye nozzle, the top is connected with condensing unit by the road, the gas vent of condensing unit is connected with tail gas burning furnace, and the liquid outlet of condensing unit is connected with water sealed tank.
Described condensing unit comprises first-stage condenser and secondary condenser, is provided with steam jet pump between first-stage condenser and the secondary condenser.
Be provided with the condensate drain tank between the gas vent of described condensing unit and the tail gas burning furnace.
The liquid outlet of described condensing unit is connected with water sealed tank through barometric pipe.
The beneficial effect that the utility model has is: the regenerator for waste lubricating oil exhaust treatment system compiles by the tail gas with feedstock oil drying tower, lightness-removing column and molecular clock tower and enters in the caustic wash tower, tail gas is processed, tail gas after the processing enters in the tail gas burning furnace after condensation and burns, realize the thorough processing to tail gas, avoided tail gas directly to enter the phenomenon that atmosphere pollutes.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, feedstock oil drying tower vacuum condenser; 2, lightness-removing column vacuum condenser; 3, molecular clock tower vacuum condenser; 4, tail gas concetrated pipe; 5, caustic wash tower; 6, packing layer; 7, alkali lye nozzle; 8, tail gas burning furnace; 9, water sealed tank; 10, first-stage condenser; 11, secondary condenser; 12, steam jet pump; 13, condensate drain tank; 14, barometric pipe.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, feedstock oil drying tower vacuum condenser 1, the tail gas outlet of lightness-removing column vacuum condenser 2 and molecular clock tower vacuum condenser 3 is connected with tail gas concetrated pipe 4 respectively, tail gas concetrated pipe 4 is connected to the bottom of caustic wash tower 5, the middle part of caustic wash tower 5 is provided with packing layer 6, top is provided with alkali lye nozzle 7, the top is connected with first-stage condenser 10 by the road, the gas vent of first-stage condenser 10 is connected with secondary condenser 11 behind steam jet pump 12, the gas vent of secondary condenser 11 is connected to tail gas burning furnace 8 behind condensate drain tank 13, the liquid outlet of first-stage condenser 10 and secondary condenser 11 is connected with water sealed tank 9 through barometric pipe 14 respectively.
Operation principle is:
With feedstock oil drying tower vacuum condenser 1, lightness-removing column vacuum condenser 2, the tail gas of molecular clock tower vacuum condenser 3 three parts enters caustic wash tower 5 through tail gas concetrated pipe 4, compound concentration is 5~10% organic alkali lye, squeeze into caustic wash tower 5 through NaOH solution circulating pump, spray downwards through alkali lye nozzle 7, tail gas in the tail gas concetrated pipe 4 enters from caustic wash tower 5 bottoms, contact in that packing layer 6 and alkali lye are reverse, acidic materials and alkali lye in the tail gas react, mainly be to remove the part sulphur-containing substance, tail gas after alkali cleaning enters first-stage condenser 10 from caustic wash tower 5 Base top contacts, with the steam in the tail gas and can coagulate oil gas condensation and get off, fixed gas enters secondary condenser 11 from first-stage condenser 10 tops after steam jet pump 12 is extracted out, water vapor condensation is got off, fixed gas is drawn by pipeline from secondary condenser 11 tops and is entered condensate drain tank 13, and then tail gas enters tail gas burning furnace 8 and burns.
At the small-sized steam jet pump 12 of first-stage condenser 10 rear installations, on the one hand can make exhaust system before first-stage condenser 10, be in negative pressure state, can be on the other hand tail gas and enter tail gas burning furnace 8 power is provided.First-stage condenser 10 enters water sealed tank 9 with the condensate liquid of secondary condenser 11 through barometric pipe 14, and water sealed tank 9 plays two aspect effects, and the one, as the water seal of barometric pipe 14, the 2nd, play the oil removal effect, a small amount of condensed oil in the condensate liquid is reclaimed.
