After gas, exhausted air quantity increases, and certainly will increase processing equipment size, increases construction investment and floor space.Institute is general in this way to be used
After dilution can in line high temperature low-concentration industrial exhaust gas up to standard, not for the high concentration hot industry exhaust gas that need to be further processed
With economic feasibility.
Absorption process be purification the most common method of gaseous pollutant, can be used for purify containing SO2, NOx, HF, SiF4, Hcl,
The industrial waste gas of Cl2, NH3, mercury vapour, acid mist, organic steam.Common absorbent have water, alkaline solution, acid solution,
Oxidizing agent solution and reducing agent solution etc..Its basic principle is to handle exhaust gas with liquid-absorbant appropriate to remove one of which
Or the method for multiple pollutant combination.Whether with chemical reaction absorption is divided into chemical absorbing and Physical Absorption by absorption process
Two major classes.But for hot industry exhaust-gas treatment, although absorption process is effective for the removal of pollutant, for absorbing
Equipment must use high temperature resistant, corrosion resistant material.Equipment manufacturing cost is caused to improve, i.e., construction investment increases, and cost performance declines, and makes
Application of the absorption process in high-temp waste gas processing is restricted.
Absorption method is to make exhaust gas contact with porous solid wherein pollutant is made to be adsorbed on the surface of solids to from exhaust gas
The method separated.The generally active charcoal of adsorbent, activated alumina etc..Because adsorbent limited by adsorption capacity and
Adsorption capacity can be reduced when high temperature, so general this method is suitable for processing low concentration industrial waste gas.
