Abstract
Vacuum tail gas cooling absorption recycling device is related to a kind of device that the tail gas that vacuum buffer tank discharges can cool down to recovery.Organic steam mainly to solve the problems, such as not condense fully in existing vacuum buffer tank is expelled directly out entering in air and designed from exhaust port.It includes vacuum buffer tank, connected between the import of the exhaust port and vavuum pump of vacuum buffer tank by pipeline, solvent recovery tank is provided with cooling water inlet and coolant outlet, the cooling coil being connected with cooling water inlet and coolant outlet is provided with solvent recovery tank, bubbler orifice plate is set in solvent recovery tank below cooling coil, solvent recovery tank top is provided with safety valve, the pipeline of vacuum pump outlet connection extend into the lower section of bubbler orifice plate in solvent recovery tank, absorbing liquid import and material outlet are additionally provided with solvent recovery tank, it is connected between circulating pump and solvent recovery tank by pipeloop.Advantage is to reduce to waste, and mitigates environmental pollution.
Description
Technical field：
It the utility model is related to a kind of device that the tail gas that vacuum buffer tank discharges can cool down to recovery.
Background technology：
Exhaust port is set on existing vacuum buffer tank, the organic steam not condensed fully in vacuum buffer tank is arranged from tail gas
Put mouth to be expelled directly out entering in air, both caused to waste, pollute environment again.
The content of the invention：
Technical problem to be solved in the utility model is to provide a kind of can cool down to the tail gas in vacuum buffer tank
Recovery, so as to reduce the vacuum tail gas of waste cooling absorption recycling device.
What above-mentioned purpose was realized in：It includes vacuum buffer tank, the exhaust port and vavuum pump of vacuum buffer tank
Import between connected by pipeline, in addition to solvent recovery tank, solvent recovery tank is built with higher boiling absorbing liquid, solvent recovery
Tank is provided with cooling water inlet and coolant outlet, is provided with solvent recovery tank and is connected with cooling water inlet and coolant outlet
Cooling coil, set bubbler orifice plate in the solvent recovery tank below cooling coil, solvent recovery tank top is provided with safety valve, very
The pipeline of empty pump discharge connection extend into the lower section of bubbler orifice plate in solvent recovery tank, in addition to circulating pump, solvent recovery tank
On be additionally provided with absorbing liquid import and material outlet, be connected between circulating pump and solvent recovery tank by pipeloop.
The utility model has the advantages that：Absorbed using the higher boiling absorbing liquid in solvent recovery tank, force tail gas liquefaction.By
In setting cooling coil in solvent recovery tank, the heat of condensation that gas discharges in liquefaction process is taken away with cooling coil, prevents normal pressure
Under secondary volatilization.Due to that provided with circulating pump, material mass-and heat-transfer can be accelerated, improve cooling and absorption efficiency.Due in solvent
Bubbler orifice plate is set in recycling can, steam can be made to form micro-bubble, so as to strengthen absorbability.So the present apparatus can both be reduced
Waste, and can mitigates the pollution to environment.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
Embodiment：
Reference picture 1, it includes vacuum buffer tank 1, leads between the import of the exhaust port and vavuum pump 2 of vacuum buffer tank
Piping connects, in addition to solvent recovery tank 3, and solvent recovery tank is provided with cold built with higher boiling absorbing liquid, solvent recovery tank
But water inlet 4 and coolant outlet 5, solvent recovery tank is interior to be provided with the cooler pan being connected with cooling water inlet and coolant outlet
Pipe 6, bubbler orifice plate 7 is set in the solvent recovery tank below cooling coil, solvent recovery tank top is provided with safety valve 8, vavuum pump
The pipeline of outlet connection extend into the lower section of bubbler orifice plate in solvent recovery tank, in addition to circulating pump 9, is gone back on solvent recovery tank
Provided with absorbing liquid import 10 and material outlet 11, it is connected between circulating pump and solvent recovery tank by pipeloop 12.
