Description

A kind of chlorobenzene exhaust-gas treatment tank
Technical field
The present invention relates to technical field of waste gas treatment, especially a kind of chlorobenzene exhaust-gas treatment tank.
Background technology
Pollutant in chlorobenzene waste gas includes chlorobenzene, 1,2- dichloro-benzenes, 1,3- dichloro-benzenes, trichloro-benzenes, tetrachlorobenzene etc. totally 12 Homologue is planted, they are widely used in all trades and professions, and including materials synthesis, agricultural chemicals, medicine etc., most of such material is difficult quilt Institute of Micro-biology degrades, easily Enriching accumulation in the environment, and major part has carcinogenic, teratogenesis, mutagenesis etc. to people and biology Toxic action.
The processing method of chlorobenzene waste gas has absorption method, condensation method, membrane separation process and bioanalysis etc..
Absorption method refers to be fixed one or more different component Adsorption Concentrations in waste gas using porosu solid adsorbent In its surface, the purpose for other components separate is reached, be the most ripe method of current most widely used, technology, general selection is inhaled Attached ability is strong, raw material is sufficient and reproducible adsorbent, such as activated carbon.The method purification efficiency is high, pollutants removal rate is high, nothing two Secondary pollution and equipment is simple, beneficial to realizing automation, easy to operate;Have the disadvantage that adsorption capacity not high is unsuitable for processing high concentration Waste gas, adsorbent is required to waste gas component, is easily failed when having other impurities, is frequently changed adsorbent and is also resulted in great number cost.
Condensation method is the physical property under condition of different temperatures using material with different saturated vapor pressures, by reducing System temperature improves the process that system pressure makes the organic matter in steam condition condense and be separated from waste gas.Should Without being related to complex separations technology, process is simple to have the disadvantage the certain pressure of processing procedure needs and temperature, treatment low concentration gives up method Gas high cost.
Membrane separation process comes across eighties of last century sixties earliest, at that time mainly for desalting processing and desalinization, and It is now widely used in every profession and trade, such as petrochemical industry, pharmacy.The method is mainly led to using waste gas each component under pressure promotion Speed when crossing selective membrane is different, so that target contaminant is separated with other components.The method simple structure, low energy consumption is high The rate of recovery and non-secondary pollution, but the price of critical component film is high, and difficult in maintenance, processing speed is slow, so at present can't Reach large-scale application.
Biochemical method waste gas is the new Organic Waste Gas Pollution control technology for developing rapidly in recent years, biological earliest Method is to be applied to deodorization treatment.Early 1980s are risen in Holland and Germany, gradually receive the U.S., Japan and other Europe The attention of man of the U.S., has currently turned into one of main method of VOCs treatment.
Chlorobenzene exhaust gas constituents are complicated, and qualified discharge is difficult to realize using above-mentioned single method.
