Those a few kinds does off-gas treatment equipment basically have?

　　 The consideration when enterprise of a lot of chemical industry is being built is not comprehensive, discharge waste gas inconsequently, bring about an environment pollution is serious, through in last few years of environmental protection standard rise, each enterprises also are undertaking ameliorative. Waste gas processing has very big effect to our surroundings, the method that different manufacturing company chooses in respect of industrial off-gas treatment is different. Equipment of industrial off-gas treatment basically is to point to use different engineering technology, through reclaim or purify, reduce the harmful part that arranges tail gas, obtain protection environment, purify airy equipment of a kind of environmental protection, let an environment be not polluted. Those a few kinds does equipment of that off-gas treatment basically have?

　　 1, equipment of VOCS off-gas treatment

Absorb equipment to 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. Cent of equipment of VOCS off-gas treatment is absorb, adsorptive, combustion and catalysis are purified, smooth catalysis and biology are purified, a variety of processing technology such as microtherm plasma. Equipment uses a variety of engineering technology, pass reclaim or the harmful ingredient that purify reduces industry to discharge gas, achieve the protective environment, goal that purifies waste gas.

　　 2, PP gush drenchs tower off-gas treatment equipment

Gush drenchs the tower works principle: Take gas mouth edge from tower body lower part when gas tangential enter purify a tower, pass equably next all flow paragraph rise to filling of the first class to absorb paragraph, in filling apparently, basic material produces chemical reaction in material of the acid in gas phase and fluid photograph, the acidity gas that absorbs not completely continues to rise enter gush of the first class to drench paragraph. Drench in gush paragraph in absorb fluid from all the nozzle high speed of cloth is ejective, form countless petty droplet and gas to mix adequately, contact, continue to produce chemical reaction. Next acidity gas rises to filling of the 2nd class paragraph, gush drenchs Duan Jin goes to recruit a process similarly with the first class.

The 2nd class and density of nozzle of the first class are different, force of gush hydraulic pressure is different, absorb limits of acidity gas chroma to also differ somewhat. Drench in gush paragraph reach filling paragraph the process that two-phase contacts also is material heat and conduct qualitative process. What assure this one process through dominating empty tower velocity of flow and time of sluggish lay aside is sufficient with stability. The acidity gas with lively to certain chemistry poorer sex, still need to join the exterior activator of certain amount in absorbing fluid. Of tower body most upside is demist paragraph, the absorption of carry secretly of the place in gas fluid droplet is kept clear of to come down here, the clean air after the course is handled from purify the end on the tower vent-pipe puts air.

　　 3, equipment of catalytic combustion off-gas treatment

The gas that catalytic combustion is a model, reaction of solid photograph catalysis, catalytic combustion is the activation energy that borrowed promoter to reduce reaction, make reactant element rich market raises response rate at activator surface at the same time, make its are rising inferiorly light temperature 200-300 ℃ next undertaking blaze burns that not have, oxidize decompose for CO2 and H2O, emit much quantity of heat.
