Is main component off-gas treatment equipment which a few kinds?

　　 Manufacturer of off-gas treatment equipment, basically be to use a variety of engineering technology, through reclaim or purify reduces the harmful part that arranges tail gas and harmful material, obtain protection environment, purify airy total purpose equipment of a kind of environmental protection.

Main component is off-gas treatment equipment the following kinds:

1, draw facility

Absorb a law to use low volatilize or not volatile dissolvent undertakes absorption to VOCs, the difference of recycle VOCs and absorbefacient physics property undertakes depart. The gas that contains VOCs absorbs tower bottom to enter a tower oneself inside, in ascendant process with come off-gas treatment equipment is contacted upstream from the absorbefacient of cat head, the gas after purifying by cat head eduction. After the absorbefacient that absorbed VOCs passes heat exchanger, enter ministry of strip cat head, in temperature prep above absorbs temperature or pressure issues desorption under the condition that absorbs pressure. The absorbefacient after desorption absorbs a tower through be being returned after solvent condenser condensation. After the VOCs gas that desorption gives passes segregator of fluid of condenser, gas leave strip tower with purer VOCs gas, be reclaimed to use. This craft agrees with the gas with taller, inferior temperature purifies VOCs chroma, the need below the circumstance makes corresponding craft adjust. Off-gas treatment equipment.

　 2, adsorptive equipment

When handling fluid mixture with porous solid matter, the some constituent in the fluid or certain constituent can be sucked the surface is thick its attend gather, this phenomenon calls adsorption. When adsorption handles waste gas, adsorptive object is gaseous contaminant, gas firm is adsorptive. Be called by adsorptive aeriform constituent adsorption is qualitative, poriferous solid matter calls sorbent.

Solid surface is adsorptive after adsorption is qualitative, one can be broken away from from sorbent surface character by adsorptive adsorption, this is added now. And after adsorption has period of time, as a result of the strong market with exterior qualitative adsorption, make its adsorptive the requirement that ability drops apparently and adsorption purifies, right now need uses certain measure to make the adsorptive already adsorption on sorbent qualitative desorption, with assist the adsorptive ability of off-gas treatment equipment, this process calls the second birth of sorbent. Manufacturer of off-gas treatment equipment explains solid to be accordingly in actual and adsorptive project, use adsorption to be born to circulate adsorptively again and again again and again just about process, the pollutant in achieving eliminate waste gas reclaims in waste gas useful constituent.
