Organic waste gas rotating wheel treatment device

Abstract

The invention discloses an organic waste gas treatment device comprising a concentration rotating wheel for adsorbing waste gas, a desorption heating assembly, a heat accumulating type catalytic combustion furnace for treating desorption waste gas of the concentration rotating wheel, and a discharge chimney, when the equipment is started, a first reverse circulation pipe and a second reverse circulation pipe are used for backflushing the regenerative catalytic combustion furnace to improve the activity of a catalyst, so that the catalyst does not need to be frequently replaced, and the servicelife of the catalyst is prolonged.

Description

technical field [0001] The invention relates to the field of waste gas treatment, in particular to an organic waste gas runner treatment device. Background technique [0002] With the rapid development of my country's economy, air pollution is becoming more and more serious. Volatile organic compounds (VOCs) combine with other pollutants in the air to form a secondary organic sol pollution source under the irradiation of sunlight. It can directly enter and stick Attached to the human respiratory tract and lung lobes, it can cause various respiratory diseases such as rhinitis and bronchitis, and can also induce cancer. The purification of organic waste gas is divided into recovery technology and destruction technology. The zeolite concentration runner combined with the regenerative catalytic combustion furnace (RCO) organic waste gas treatment device is an optimized combination of the two, which has a good organic waste gas treatment effect. [0003] However, the surface acti...

Problems solved by technology

[0003] However, the surface activity of the catalyst in the regenerative catalytic combustion furnace decreases after a long time of use, which will cause the problem of incomplete combustion of the concentrated organic waste gas, making the treated exhaust gas unable to meet the emission standards. Therefore, the current regenerative catalytic combustion furnace The catalyst of the catalytic combustion furnace needs to be replaced frequently, which is inconvenient

[0004] In addition, both the zeolite enrichment wheel and the regenerative catalytic combustion furnace need to be preheated when starting up. During the preheating process, organic waste gas cannot be treated, and a large amount of energy will be consumed, which leads to a high cost for each start-up of the equipment.
