Abstract

The invention discloses a VOC decomposition composite-purifying processing apparatus and a method. the apparatus comprises a tower body, a circulation water pool for holding tap water, and a composite decomposition water pool for holding a spraying liquid; the tower body is inside successively provided with an air intake, a first liquid collector, a first filler layer, a first liquid distributor, a second liquid collector, a second filter layer, a second liquid distributor, a gas-liquid separator and an air outlet. By employing the provided VOC decomposition composite-purifying processing apparatus for processing VOC exhaust gas, the following advantages are provided: the purification effect is stable and reaches the standard, one-time investment is much less than that of a conventional active carbon technology, and the operating cost is reduced by 90% or more compared with that of a conventional active carbon technology.

Description

technical field [0001] The invention relates to the field of waste gas treatment, in particular to a VOC decomposition compound purification treatment device and method. Background technique [0002] VOCs compounds refer to the general term of non-methane total hydrocarbons detected by hydrogen flame ion detector, including low-boiling hydrocarbons, oxygen hydrocarbons, halogen-containing hydrocarbons, nitrogen hydrocarbons, sulfur hydrocarbons, alcohols, and aldehydes , ethers, acids, amines, etc., with a wide variety and wide distribution. According to the list of major foreign environmental pollutants, VOCs compounds account for more than 80%. VOCs compounds mainly come from petrochemical, pharmaceutical, furniture, printing, electronics, painting, footwear, papermaking, surface anticorrosion, transportation, metal plating and textile industries. VOCs compound pollution is very serious, such as photochemical reaction with NOx, CnHm (hydrocarbons) under the action of sun...
