Abstract
The utility model provides a tail gas safe recovery device among spent lubricating oil regenerative process, includes ordinary pressure evaporimeter, condenser, oil -gas separation post, oily storage tank and water sealed tank, and ordinary pressure evaporimeter, condenser and oil -gas separation post connect gradually, and the lower part of oil -gas separation post is passed through oil pipe and is said and be connected with oily storage tank, and the top of oil -gas separation post is passed through the trachea way and is connected with the water sealed tank, and the top of water sealed tank is provided with the opening pipeline. Tail gas among the spent lubricating oil regenerative process at first passes through ordinary pressure evaporimeter heating evaporation, and the light oil gas of production gets into the reentrant oil -gas separation post in condenser cooling back, and the oil content is said by oil pipe and get into oily storage tank that non -condensable gas is said by the trachea and gets into the water sealed tank. Non -condensable gas can get into the boiler furnace burning. The utility model discloses simple structure does not use the pumping over to send, and area is little, and safety is retrieved to tail gas, the high efficiency, and the energy consumption is little.
Description
Technical field
The utility model is related to a kind of dress for the tail gas producing in Spent lube reclamation process is carried out with safe retrieving
Put, belong to technical field of waste gas treatment.
Background technology
Domestic waste lubricating oil refines base oil technique, how with normal pressure plug, sulfuric acid treatment one milk of lime carclazyte work, its work
Skill is complicated to fall behind, and goods and materials waste, and environmental pollution is serious.The regeneration of external waste lubricating oil is how based on hydrogenation technique.
According in August, 2000 second printing distribution of Sinopec publishing house《Waste lubricant oil regeneration》The note of the third edition
Carry, abroad adopt film distilled carclazyte technique, this technique products obtained therefrom base oil yield is only 65%, light oil 7%, and product is comprehensive
Close yield 72%, and byproduct residual oil discharge rate is up to 28%, more containing lubricating oil component in residual oil, account for the 20% of residual oil amount
Left and right, this kind of residual oil added value is very low, belongs to hazardous waste, and residual oil amount is excessive.
Additionally, the vent gas treatment in Spent lube reclamation process is also critically important link.CN202700351U discloses
A kind of《Regenerator for waste lubricating oil exhaust treatment system》, including feedstock oil drying tower vacuum condenser, lightness-removing column vacuum condensation
Device and molecular clock tower vacuum condenser, feedstock oil drying tower vacuum condenser, lightness-removing column vacuum condenser and molecular clock tower
The offgas outlet of vacuum condenser is connected with tail gas concetrated pipe respectively, and tail gas concetrated pipe connects to the bottom of caustic wash tower, alkali cleaning
The middle part of tower is provided with packing layer, and top is provided with alkali lye nozzle, and top is connected with condensing unit by the road, the gas of condensing unit
Outlet is connected with tail gas burning furnace, and the liquid outlet of condensing unit is connected with water sealed tank.
Above-mentioned regenerator for waste lubricating oil exhaust treatment system is although achieve the thorough process to tail gas, it is to avoid tail
Gas is directly discharged into the phenomenon that air pollutes, but complex structure, power consumption height.
Content of the invention
The utility model is directed to the deficiency that existing waste lubricating oil refines tail gas disposal technique presence during base oil, provides
A kind of tail gas safe recovery device in safe efficient, Spent lube reclamation process that energy consumption is little.
Tail gas safe recovery device in Spent lube reclamation process of the present utility model, employs the following technical solutions：
This device, including atmospheric evaporation device, condenser, Oil-gas Separation post, oil tank and water sealed tank, atmospheric evaporation device, cold
Condenser and Oil-gas Separation post are sequentially connected, and the bottom of Oil-gas Separation post is connected with oil tank by oil-piping, Oil-gas Separation post
Top is connected with water sealed tank by feed channel.
It is provided with control valve on described oil-piping.
The top of described water sealed tank is provided with opening conduit, to make the gas isolated discharge, uses as combustion gas.
Tail gas in Spent lube reclamation process first passes around atmospheric evaporation device heating evaporation, and the light oil gas entrance of generation is cold
Oil-gas Separation post is entered back into, oil enters oil tank by oil-piping, and on-condensible gas enters water sealed tank by feed channel after condenser cooling.
On-condensible gas can enter boiler furnace burning.
The utility model structure is simple, does not use pump to convey, floor space is little, tail gas recycle safety, and efficiently, energy consumption is little.
Brief description
Fig. 1 is the structural representation of the tail gas safe recovery device in the utility model Spent lube reclamation process.
Wherein：1. atmospheric evaporation device, 2. condenser, 3. Oil-gas Separation post, 4. oil tank, 5. water sealed tank, 6. opening conduit,
7. feed channel, 8. oil-piping.
Specific embodiment
This device includes atmospheric evaporation device 1, condenser 2, Oil-gas Separation post 3, oil tank 4 and water sealed tank 5.Atmospheric evaporation device
1st, condenser 2 and Oil-gas Separation post 3 are sequentially connected, and the bottom of Oil-gas Separation post 3 is connected with oil tank 4 by oil-piping 8, oil gas
The top of splitter 3 is connected with water sealed tank 5 by feed channel 7, and the top of water sealed tank 5 is provided with opening conduit 6.
Control valve can be provided with oil-piping 8, be opened according to the weight of oil in Oil-gas Separation post 3.
Tail gas in Spent lube reclamation process first passes around atmospheric evaporation device 1 heating evaporation, produces in atmospheric evaporation device 1
Light oil gas enter condenser 2 and cool down, light oil gas after cooling enters Oil-gas Separation post 3, and oil enters oil by bottom oil-piping 8
Storage tank 4, on-condensible gas enters the bottom of water sealed tank 5 by the feed channel 7 at Oil-gas Separation post 3 top, then opening by water sealed tank 5 top
Mouth pipeline 6 enters boiler furnace burning.
