Abstract

The invention relates to the technical field of waste gas treatment equipment, especially to an industrial harmful waste gas treatment device based on a VOC biological method. The device comprises a treatment chamber and an activated sludge chamber, wherein a porous filler layer is arranged at the inner upper end of the treatment chamber; a liquid inlet pipe is arranged between and communicates with the treatment chamber and the activated sludge chamber; the bottom ends, located in the treatment chamber, of liquid inlet manifolds communicate with a plurality of evenly-distributed spray heads;a heat exchange chamber is arranged at the bottom end of the treatment chamber; and a quantity-controlling gas inlet mechanism is arranged in the treatment chamber. According to the invention, a heatexchange coil and the heat exchange chamber are arranged and matched with each other to cool high-temperature waste gas, so the rising speed of the waste gas in the treatment chamber is reduced, and the mass transfer time of waste gas and spraying liquid is prolonged; and quantitative gas inflow and quantitative gas outflow of large-flow waste gas are achieved by arranging the quantity-controllinggas inlet mechanism.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment equipment, in particular to an industrial harmful waste gas treatment device based on a VOCs biological method. Background technique [0002] The VOCs biological method is a process in which microorganisms attached to the filter medium use the organic components in the exhaust gas as carbon sources and energy sources to maintain their life activities and decompose organic matter into CO2 and H2O under suitable environmental conditions. VOCs (Volatile Organic Compounds) in the main body of the gas phase undergo a mass transfer process from the gas phase to the liquid or solid phase, and then are decomposed by microorganisms in the liquid or solid phase. [0003] Common biological methods for treating VOCs include biological scrubbing. The biological scrubbing process is a suspended activated sludge treatment system consisting of an absorber with inert filler and an activated sludge reac...
