Description
Technical Field
The utility model relates to a tail gas treatment system especially relates to a system for handle tail gas in benzophenone production process.
Background
Benzophenone is an important intermediate for organic synthesis and is widely applied to the fields of organic coatings, dyes, adhesives, printing ink, plastics, medicines, daily chemical industry, spices and foods, pesticides, electronic chemicals and the like. Therefore, the market demand of benzophenone is extremely large, and manufacturing enterprises are more, but the tail gas treatment in the production process of benzophenone is found to be unfavorable in the production process of benzophenone, and in the conventional production, the tail gas emission and pressure relief are needed after the benzophenone is synthesized in a reaction kettle. At the moment, the tail gas is discharged after being absorbed and filtered by simple alkali liquor, so that the environment is seriously influenced, and the environment-friendly production enterprises are not easy to establish; and benzene in the tail gas is not absorbed and utilized, which is not beneficial to reducing the production cost.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned not enough, provide a high-efficient tail gas treatment system of benzophenone, its effectual reduction to the pollution of environment.
The purpose of the utility model is realized like this:
the utility model provides a high-efficient tail gas processing system of benzophenone, the system includes the condenser, and the tail gas is managed to communicate to the air intake of condenser, and the air outlet of this condenser communicates to the air inlet of absorption tank through the pipeline, the air inlet that gets into the absorption tank behind the absorption tank in the gas outlet of absorption tank, the air inlet that communicates to the packing jar in the gas outlet of this absorption tank, and the gas outlet of this packing jar communicates to the bottom air inlet of exhaust chimney through the molecular sieve.
The utility model relates to a high-efficient tail gas processing system of benzophenone, the splendid attire has water in the absorption tank, the splendid attire has alkali lye in the absorption tank.
The utility model relates to a high-efficient tail gas processing system of benzophenone, the canopy of a toper structure is installed at the top of exhaust chimney.
The utility model relates to a high-efficient tail gas processing system of benzophenone, the bottom liquid outlet of condenser communicates to benzene recovery unit.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model can filter the polluting gas in the tail gas during the emission by performing multiple purification on the tail gas, thereby reducing the environment to the environment; meanwhile, the front-end condensation is utilized, so that the benzene in the tail gas can be conveniently recycled, and the production cost is reduced.
