Embodiment
In order to more clearly state the utility model, the utility model is further described below in conjunction with the accompanying drawings.
As shown in Figure 1, the device for recovering tail gas includes liquid acid anhydride storage tank 1, air ejector 2 and switch condenser 3；Institute
The top for stating liquid acid anhydride storage tank 1 is equipped with exhaust pipe 11, and the exhaust pipe 11 is connected with the air ejector 2.It is described
Air ejector 2 is using air as power source, and the phthalic anhydride dust of volatilization and air in the liquid acid anhydride storage tank 1 are transported to together
In switch condenser 3, the volatilization phthalic anhydride dust for solving liquid acid anhydride storage tank 1 in the prior art is blown out, cause environment pollution and
The loss of phthalic anhydride.
The air ejector 2 is equipped with air inlet pipe 21 and drainage conduit 22, and the drainage conduit 22 connects with the switch condenser 3
Connect, the air inlet pipe 21 is equipped with pressure gauge 211.The pressure gauge 211 can be seen when air enters in the air inlet pipe 21
Pressure, user can calculate air mass flow situation by observing the pressure gauge 211, if while it was observed that pressure gauge 211
Registration, beyond normal ranges, can make user find out problem device in time, avoid the generation of danger.
A kind of above-mentioned liquid acid anhydride tank roof device for recovering tail gas, the liquid acid anhydride storage tank 1 are internally provided with temperature-adjusting device 12.
The temperature of the liquid acid anhydride storage tank 1 needs to control at 150 DEG C -160 DEG C, and the temperature-adjusting device 12 exceeds temperature range in temperature
When, adjust the temperature in the liquid acid anhydride storage tank 1.
A kind of above-mentioned liquid acid anhydride tank roof device for recovering tail gas, the liquid acid anhydride storage tank 1 are equipped with liquid acid anhydride feed pipe 13 and liquid acid anhydride
Discharge nozzle 14, the liquid acid anhydride feed pipe 13 are equipped with flow control valve 131.Liquid acid anhydride described in 131 observable of flow control valve
The flow condition of liquid acid anhydride in feed pipe 13, convenient for users to understanding the use parameter of the liquid acid anhydride storage tank 1 in time.
The embodiment created above to the utility model is described in detail, but the content is only the utility model wound
The preferred embodiment made, it is impossible to be construed as limiting the scope of the utility model.It is all to create scope according to the utility model
All the changes and improvements made etc., should all still belong within this patent covering scope.
