Abstract

The invention relates to the technical field of organic waste gas treatment, in particular to a method for using thermal plasma to heat treat organic waste gas. It includes the following steps: gas pretreatment and purification, molecular sieve adsorption and desorption, gas ultra-high temperature cracking and combustion, and tail gas treatment. The thermal plasma pyrolysis equipment provided by the present invention has a high temperature in the combustion working area, a heating block, and a more thorough exhaust gas cracking and combustion effect; when the thermal plasma pyrolysis equipment is working, it does not need external air to supplement the air for combustion, which greatly reduces the gas intake and The tail gas treatment capacity greatly reduces the cost of use; the core area of ​​the thermal plasma pyrolysis equipment can be fed with protective gas as needed, and the protective gas can realize high-temperature anaerobic pyrolysis of organic waste gas, thereby effectively controlling the generation of nitrogen oxides, and can Completely avoid the risk of explosion.

Description

technical field

[0001] The invention relates to the technical field of organic waste gas treatment, in particular to a method for using thermal plasma to heat treat organic waste gas. Background technique

[0002] At present, in the field of industrial organic waste gas treatment, waste gas treatment technologies such as direct combustion waste gas (TO), regenerative combustion (RTO), regenerative catalytic combustion (RCO), activated carbon adsorption, and plasma treatment are mainly used. Related technologies can be used alone or in combination Perform exhaust gas treatment.

[0003] Among the above-mentioned organic waste gas treatment technologies, some technologies need to rely on efficient heat sources. For example, TO and RTO require gas burners as heat sources to maintain high-temperature combustion, and RCO and activated carbon adsorption and desorption require electric power supplies. However, some technologies have high investment and use costs, such as plasma tr...
