Problems solved by technology

[0002] The adsorption area of ​​the viscose fiber waste gas treatment system belongs to the explosion-proof area, so the requirements for each component are relatively high, especially the automatic control instrument valve requires zero leakage, but the actual situation can hardly reach the ideal state. The instrument valve is divided into pneumatic pollution The air valve, fresh hot air valve, and main valve are switched on and off through program control. Because the pneumatic dirty air valve passes carbon disulfide gas and the hot air through the fresh hot air valve, once the two communicate with each other, it will cause safety hazards in production.

Abstract

The invention discloses a valve internal leakage detection device of a viscose waste gas treatment system adsorption area. The valve internal leakage detection device comprises a main air pipe, wherein one end of the main air pipe is connected to carbon disulfide gas, the other end of the main air pipe is connected with a carbon disulfide adsorption groove, the main air pipe, close to the end of the carbon disulfide gas, is provided with a pneumatic waste gas valve, the middle part of the main air pipe is connected with fresh hot air through a fresh hot air connecting pipe, a fresh hot air valve is arranged on the fresh hot air connecting pipe, the main air pipe, close to the end of the carbon disulfide adsorption groove, is provided with a temperature detection device, and the temperature detection device is connected with a computer control device though a conductor.

Description

technical field [0001] The invention relates to an industrial waste gas treatment equipment, in particular to a device for detecting internal leakage of a valve in an adsorption area of ​​a viscose fiber waste gas treatment system. Background technique [0002] The adsorption area of ​​the viscose fiber waste gas treatment system belongs to the explosion-proof area, so the requirements for each component are relatively high, especially the automatic control instrument valve requires zero leakage, but the actual situation can hardly reach the ideal state. The instrument valve is divided into pneumatic pollution The gas valve, fresh hot air valve, and main valve are switched on and off through program control. Because the pneumatic dirty air valve passes carbon disulfide gas and the fresh hot air valve passes hot air, once the two communicate with each other, it will cause safety hazards in production. Contents of the invention [0003] The technical problem to be solved by ...
