The utility model discloses a tail gas processing apparatus of multiple structure, function forms one set of complete can handle multiple harmful gas, and tail gas treatment more thorough tail gas processing apparatus, makes tail gas obtain thorough purification, environmental protection more.
Description
Technical Field
The utility model belongs to the technical field of chlorocyclohexane production facility, concretely relates to a tail gas absorbing device for chlorocyclohexane production.
Background
The chlorocyclohexane is a basic raw material for organic synthesis and is also an important fine chemical product. It is mainly used as the intermediate of rubber scorch retarder CTP, pharmaceutical dipheny hydrochloride, pesticide cyhexatin and other products; can also be used for synthesizing polyurethane foaming catalysts, such as N, N-dimethylcyclohexylamine, antirust agent and the like. Cyclohexane and chlorine are used as raw materials in the preparation method of chlorocyclohexane, and chlorine atom replaces one hydrogen atom on a cyclohexane ring to generate chlorocyclohexane and hydrochloric acid gas. The hydrochloric acid gas and a small amount of overflowed chlorine gas are discharged as tail gas. The existing production process generally adopts clear water to absorb tail gas to form industrial salt, but attention is paid to environmental protection at present, and the simple treatment method meets the emission requirement.
Disclosure of Invention
The utility model aims at the above problem, provide a tail gas absorbing device for chlorocyclohexane production, to the more thorough processing of harmful gas, reach the emission requirement.
The utility model is realized in such a way, a tail gas absorption device for chlorocyclohexane production is characterized in that the device mainly comprises a water curtain cabinet, an air pump, a falling film absorber, a circulating absorption tower, a photocatalytic decomposition device and an activated carbon tank; the air outlet of the water curtain cabinet is connected to the bottom of the falling film absorber through an air pump, the top of the falling film absorber is connected to the lower part of the circulating absorption tower through a pipeline, and the air outlet at the upper part of the circulating absorption tower is connected to the photocatalytic decomposition device through a pipeline and finally connected to the activated carbon tank.
Tail gas enters the falling film absorber from the water curtain cabinet after being treated, is pumped into the falling film absorber through the air pump, and then is sent into the circulating absorption tower, the gas discharged after being treated by the circulating absorption tower enters the photocatalytic decomposition device again, a small amount of gas difficult to absorb is subjected to photocatalytic shunting, finally passes through the activated carbon tank, is absorbed by the activated carbon, and finally is discharged to meet the environmental protection requirement.
The beneficial effects of the utility model reside in that: the tail gas treatment device with multiple structures and functions forms a complete tail gas treatment device capable of treating multiple harmful gases, and the tail gas treatment device is more thorough in tail gas treatment, so that tail gas is thoroughly purified and more environment-friendly.
