Abstract

The invention relates to the technical field of tail gas treatment, in particular to a biochemical coupling tail gas treatment system and a using method thereof. The biochemical coupling tail gas treatment system comprises a first-stage purification assembly, a second-stage purification assembly, a third-stage purification assembly and a fourth-stage purification assembly which are sequentially connected. Firstly, biochemical tail gas is washed and forcibly oxidized through the first-stage purification assembly; secondly, key components in the biochemical tail gas are further captured and degraded through the second-stage purification assembly; thirdly, the biochemical tail gas is dried through a semiconductor type dehumidifier; and finally, residual trace harmful components in the tail gas are deeply adsorbed and removed by an activated carbon filler layer in an adsorption tower. According to the system, different waste gas treatment means are deeply coupled, so that the system can effectively purify different harmful waste gases, and the operation cost can be reduced through the cooperation of the purification assemblies. The problems of insufficient waste gas treatment capacity, high operation cost and the like in the prior art can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of tail gas treatment, in particular to a biochemical coupling tail gas treatment system and a use method thereof. Background technique [0002] In recent years, the problem of environmental pollution has become more and more serious, especially air pollution. The waste gas emitted by many industrial productions, such as perfluorinated gas in the semiconductor industry, has a strong infrared absorption capacity in the atmosphere, and the infrared absorption capacity of CF4 is 5700 times that of CO2, so it will aggravate the greenhouse effect and increase the global average temperature. It has become the main reason for climate anomalies; secondly, the flue gas produced by coal furnace combustion contains sulfides and nitrogen oxides, which stimulates the human respiratory system and damages human health, and also produces acid rain, which destroys the earth's ecological environment and causes photochemical p...
