Honeycomb activated carbon negative pressure anti-explosion desorption treatment device and technology

Abstract

The invention relates to a honeycomb activated carbon negative pressure anti-explosion desorption treatment device and technology. The honeycomb activated carbon negative pressure anti-explosion desorption treatment device comprises a desorption chamber, wherein a first gas detection probe is arranged at a gas outlet of the desorption chamber, an automatic volume damper is arranged at the gas outlet of the desorption chamber, the gas outlet of the desorption chamber is connected with a waste gas oxidation chamber, a high temperature oxidation tube and a second temperature sensor probe are arranged in the waste gas oxidation chamber, an anti-explosion net is arranged outside the waste gas oxidation chamber and a combustible gas region between the waste gas oxidation chamber and the gas outlet of the desorption chamber, a first negative pressure fan and a second gas detection probe are arranged in a gas outlet pipeline of the waste gas oxidation chamber, a honeycomb ceramic gas distributing sieve is arranged at the gas outlet of the gas outlet pipeline of the waste gas oxidation chamber, and the honeycomb ceramic gas distributing sieve is immersed into medicament in a medicament reaction tank. The honeycomb activated carbon negative pressure anti-explosion desorption treatment device has the advantages that negative pressure oxidation and expansion pipe technologies are used in the waste gas oxidation chamber behind the desorption chamber, and the anti-explosion net is arranged outside the combustible gas region, so that safety problem is solved, and desorption gas after hightemperature oxidation can be fully contacted and reacted with the medicament by virtue of the honeycomb ceramic gas distributing sieve.

Description

technical field [0001] The invention relates to a honeycomb activated carbon negative pressure explosion-proof desorption treatment device and process, belonging to the technical field of industrial waste gas treatment. Background technique [0002] Activated carbon has a good specific surface area and strong adsorption, decolorization and deodorization properties, so it is often used as an adsorption medium in a circular purification system to absorb toxic and polluting substances in waste gas and wastewater. [0003] At present, the most commonly used adsorption and desorption recovery devices mainly include: air filter, adsorption tank, condenser, separation tank, gas blaster, etc. Two or more adsorption tanks are used simultaneously or alternately. The adsorption process is as follows: exhaust gas passes through the air filter to remove tiny suspended particles, then enters the top of the adsorption tank, and after being adsorbed by activated carbon in the tank, harmful ...
