Technical field
The invention belongs to VOC gas recovery technology fields, more particularly to a kind of VOC gas recyclable device.
Background technique
Volatile organic gases compound (Volatile Organic Compounds abbreviation VOC) is more normal in atmosphere
See and generally existing atmosphere pollution.Common component has hydrocarbon, benzene homologues, alcohols, ketone, phenols, aldehydes, ester
Class, amine, nitrile (cyanogen) class etc..VOC issues third contact of a total solar or lunar eclipse chemical reaction in illumination effect, will lead to photochemical fog, Secondary Organic gas
The raising of colloidal sol and atmosphere organic acid can destroy ozone layer, be the major reason that haze weather (PM2.5) is formed, can also show
Certain toxicity, irritation, carcinogenicity out cause large effect to human health.
Mainly there are stationary source and two kinds of moving source in the source of VOC.Moving source mainly has automobile, steamer and aircraft etc. with petroleum
