Low-concentration organic exhaust gas fluidization tower

Abstract

The invention relates to a low-concentration organic exhaust gas fluidization tower. A muddy water zone, a fluidization zone, an adsorption oxidation zone, a dehumidification zone, an activated carbon adsorption zone and an exhaust fan are arranged from bottom to top of the tower in turn; the muddy water zone is designed as a tapered structure and is used for collecting the muddy water from the upper part; a draining valve is arranged at the bottom of the tapered structure; the draining valve is connected with a sludge thickener on the outer side of the tower; a fluidization drum is arranged in the fluidization zone; the fluidization drum has a cylindrical structure and is located at the center of the fluidization zone; the lower end opening of the fluidization drum is located at the bottom of the fluidization zone while the upper end opening is located on the upper part of the fluidization zone; a gas inlet pipe and a gas distributing pipe are arranged at the lower end of the fluidization drum; the gas distributing pipe is arranged in the shape of a concentric circle; the adsorption oxidation zone is located on the upper part of the fluidization zone; the dehumidification zone is arranged on the upper part of the adsorption oxidation zone; and the activated carbon adsorption zone is arranged on the upper part of the dehumidification zone.

Description

technical field [0001] The invention relates to the technical field of air pollution control, in particular to a low-concentration organic waste fluidization tower. Background technique [0002] With the rapid development of human economic activities and production, while people consume a lot of energy, they also discharge a lot of waste gas and smoke into the atmosphere, especially the massive use of gasoline, paint, various organic solvents and other chemicals. The emission of volatile organic compounds (VOCs) has increased rapidly, making VOCs another important gaseous pollutant besides CO, SOx, and NOx. Among them, the industrial production sector has become one of the most important industries polluted by VOCs. These organic waste gases mainly include hydrocarbons (butane, methylene chloride), benzene series (benzene, toluene, xylene), alcohols (ethanol, methanol), aldehydes and ketones (formaldehyde, acetone, cyclohexanone), etc. These pollutants often have the charac...
