Description
Technical field
The utility model relates to technical field of chemical, is specifically related to a kind of means of communication of equilibrium air pressure.
Background technology
At present, chemical enterprise takes direct discharging in production discharging link, semi-finished product (finished product) pass through the direct discharging of pipeline to adjustment tank from reactor, and this process can make volume of equipment and air pressure produce significant change: reactor volume expands rapidly and forms negative pressure, need supplement air from the external world; Adjustment tank volume reduces rapidly and forms malleation, is discharged by internal gas.But, due to before chemical industry semi-finished product (finished product) discharging time reactor and adjustment tank is full of solvent gas (as toluene, ethyl acetate, methyl alcohol etc.) and temperature is higher, during discharging, adjustment tank space is extruded, and a large amount of solvent gas is extruded rapidly, and solvent cannot cool down by condenser immediately, solvent gas is made to drain into waste gas system through flue gas leading, cause waste gas system to wash/absorption inefficacy, solvent gas drains into air the most at last, contaminated environment; Reactor inner space forms negative pressure because expanding rapidly, for equilibrium air pressure, outside air is supplemented to reactor rapidly by pipeline, the solvent gas higher with reactor temperature fully mixes, and may reach explosion limit, and in supplementary process, air and solvent rub can produce electrostatic, Electro-static Driven Comb produces spark, then also may cause explosion danger, life threatening safety.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of means of communication of equilibrium air pressure.
Technical solutions of the utility model are as follows:
A kind of means of communication of equilibrium air pressure, comprise reactor, adjustment tank, first horizontal condenser, second horizontal condenser, waste gas header, valve one, valve two and communicating pipe, bypass outlet above described reactor is connected with the entrance of the first horizontal condenser, reflux inlet above described reactor is connected with the outlet of the first horizontal condenser, the waste gas outlet pipeline of described first horizontal condenser is connected with waste gas header pipeline, bypass outlet above described adjustment tank is connected with the entrance of the second horizontal condenser, reflux inlet above described adjustment tank is connected with the outlet of the second horizontal condenser, the waste gas outlet pipeline of described second horizontal condenser is connected with waste gas header pipeline, one end of described communicating pipe is connected on the waste gas outlet pipeline of the first horizontal condenser, its other end is connected on the waste gas outlet pipeline of the second horizontal condenser, described communicating pipe is provided with valve three and one way stop peturn valve, the direction of described one way stop peturn valve is through flowing to the waste gas outlet pipeline of the first horizontal condenser communicating pipe from the waste gas outlet pipeline of the second horizontal condenser, described valve one and valve two are located at first respectively, on the waste gas outlet pipeline of the second horizontal condenser, and on pipeline all between communicating pipe and waste gas header.
The beneficial effects of the utility model are: by first, a connecting pipe is connected between the waste gas outlet pipeline of the second horizontal condenser, the barotropic gas utilizing adjustment tank to be extruded in discharge process is made to carry out the negative pressure formed in postreaction still, by equipment self gas cycling and reutilization, on the one hand, avoid the environmental pollution that noxious gas emission causes, reduce the frequency of maintenance of waste gas system, on the other hand, avoid and rub produce electrostatic because outside air is supplemented to reactor and solvent gas, and the explosion danger that may cause, effectively prevent the generation of security incident, in addition, communicating pipe increases valve three and one way stop peturn valve, effectively prevent the contamination of products caused because the gas of reactor in production process drains into adjustment tank.
