Abstract

The invention relates to the field of environment protection, and discloses a purifying device which comprises a fluidized bed. The fluidized bed comprises a hollow reaction pipe, a gas inlet and a gas outlet, wherein the gas inlet and the gas outlet are formed in the two ends of the reaction pipe. Biomass conductive carbon particles are arranged in the reaction pipe and can be in a fluidized state under the effect of gas flow. The purifying device further comprises a high-voltage electrode and a low-voltage electrode which are arranged on the two sides of the fluidized bed. Organic pollutantgas enters the reaction pipe, the potential difference is formed between the high-voltage electrode and the low-voltage electrode, the biomass conductive carbon particles in the fluidized state are broken down to form discharging, and the organic pollutant gas is degraded. By means of the purifying device, energy consumption can be reduced, and the organic pollutant gas degradation capacity can beimproved.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a purification device. Background technique [0002] Organic pollutant gases (toluene, formaldehyde, etc.) are common pollutants in production and life, which not only affect human health and destroy the ecological environment, but also may cause fine particles (such as PM2.5), ozone (O 3 ) and other characteristics of regional atmospheric complex pollution problems. At present, the methods for treating organic pollutant gases mainly include absorption method (such as activated carbon), combustion method, catalytic degradation method, and decomposition method (such as photolysis, ozone decomposition, plasma decomposition) and so on. [0003] All living organic substances that can grow are collectively called biomass, which includes plants, animals and microorganisms. Biomass is a kind of solar energy. The annual carbon fixed by plant photosynthesis on the earth is as high...
