Abstract
The utility model discloses a guiding device for the recovered trichlorosilane tail gas, comprising a main pipeline system and an emergency pipeline system which are in parallel connection at an inlet, wherein the main pipeline system is formed by connecting a tail gas buffer tank with a blower in series. The device further comprises a pressure automatically-adjusted valve bank connected with the blower in parallel and a bypass valve connected with the automatically-adjusting valve bank in parallel; and the main pipeline system is connected into a tail gas recovery system. The emergency pipeline system comprises an emergency pressure-relief valve, a bypass valve connected with the emergency pressure-relief valve in parallel and a leaching tower. By implementing the device, the pollution of trichlorosilane to the environment can be avoided and hydrochloric acid and silica residue can be reduced; meanwhile, the device creates certain economic benefit for enterprises.
Description
Technical field
The utility model relates to a kind of walking apparatus of leading of trichlorosilane tail gas recovery.
Background technology
In production process of trichlorosilane, need be applied to power-equipments such as multiple compressors, vavuum pump, air blast, all contain chemical gases such as trichlorosilane in the gas that they are carried, and trichlorosilane belongs to flammable explosive gas, and characteristics such as forbidding to contact water and air is arranged.Power-equipment is in service, leaks in order to prevent trichlorosilane gas, causes the infringement to other part of device interior, generally is provided with the nitrogen-sealed protective device between cylinder and bent axle.This device has nitrogen air inlet and exhaust outlet, contain gases such as a spot of trichlorosilane in the nitrogen that nitrogen envelope exhaust outlet is discharged, the at present domestic method that generally adopts is, directly nitrogen envelope gas row in atmosphere or connect interim pipe and enter and carry out simple absorption in the bucket and handle.
Equipment needs with nitrogen equipment to be replaced before maintenance, contain a large amount of gases such as trichlorosilane in the gas of displacement, forbid directly to enter atmosphere, need rationally to dispose, usually the method for disposal of taking is to be discharged into eluting column, materials such as the trichlorosilane in the gas are absorbed by the water in the eluting column, generate hydrochloric acid and silica white residue simultaneously, have secondary pollution.
More than two kinds of gas purgings all environment is caused severe contamination, caused a large amount of wastes of recyclable chemical industry materials such as trichlorosilane simultaneously.
The utility model content
The utility model provides a kind of walking apparatus of leading that is specifically designed to the trichlorosilane tail gas recovery.
The technical solution of the utility model is: a kind of trichlorosilane tail gas reclaims leads walking apparatus, this device is included in the main line system and the emergency line system of porch parallel connection, described main line system is in series by tail gas buffer, air blast, it has also comprised the pressure automatic regulating valve group in parallel with described air blast, with described automatic regulating valve group bypass valve in parallel, described main line system inserts exhaust gas recovery system.Described emergency line system comprises emergency pressure relief valve, bypass valve and the eluting column in parallel with described emergency pressure relief valve.
The beneficial effects of the utility model are: the enforcement of this device, avoided the pollution of trichlorosilane to environment, and reduced the generation of hydrochloric acid and silica white residue, created certain economic benefits for enterprise simultaneously.
