Grand rich environmental protection and you share the waste gas that in how handling industry to produce with activated carbon, appears

Activated carbon must come because of its powerful adsorptive ability the wide application of people, it is in besides application a few commonner application still have a few everybody to hit newer field to also apply it beyond the domain, so you know activated carbon application is inIndustrial off-gas treatmentIf why handle industry be if why handle industry,of waste gas in? Everybody can follow us below grand rich environmental protection is little make up understand together.

Activated carbon is commonly used sorbent, have property stable, fight corrode wait for an advantage. As a result of its hydrophoby, have blame polarity face, for hydrophoby and hydrophily the sorbent of organic matter, often be used to adsorption reclaims effluvial material and organic material, the organic matter in stink of adsorption of can better land and H2S.

　　 Its are main technical principle is:

1. Activated carbon has space of larger target compound adsorption, reason adsorption has the ability of machine content gas to increase apparently.

2. Capability of reaction of activated carbon stimulative oxidation is stronger, in adsorptive process, activated carbon H2S and oxygen adsorptive in its apparently, the H2SO4 that produces oxidation to generate 90% above and a few H2SO3 and S

The adsorptive ability of activated carbon depends on it having tremendous comparing to express an area, and its elaborate poriferous surface structure, it has microcrystalline structure, microcrystalline arrange irregular, there is small opening in crystal (radius is less than rice of =-10 of 20 〔 dust 〕 ) , transfer aperture (radius 20 ～ 1000 dust) , large hole (radius 1000 ～ 100000 dust) , the metallic ion in OK and adsorptive liquid waste and waste gas, harmful gas, organic contaminant, pigment, flavour and deodorization are taken off in suiting off-gas treatment process, and its desorption procedure is very simple also. Next graphs are the process signal of activated carbon adsorption:

Waste gas enters a tower by air inlet inside, the course removes dust net, cross filter layer, in waste gas harmful composition by filter layer adsorption hind, the headroom of aeriform by chimney after purifying

Unit of adsorption of activated carbon of grand rich environmental protection is main wait for composition by conduit of casing of device of activated carbon adsorption, imports and exports, fan, chimney.

Casing of device of activated carbon adsorption: 1. Filter inside casing of carapace of Yu Gang of filter makings outfit, what want the contaminative air of processing in order to isolate, casing solders by carbolic stencil steel and become. 2. Tower body sets overhaul door, facilitate change filter makings and tower body are safeguarded. 3. Activated carbon filter expects layer structure uses design of drawer box type, the structure is compact, facilitate change. The box is mixed by steel frame perforation board solders composition. Frame passes spot welding to secure for hypostatic metal, perforation board go up in frame, inside box the cavity that forms between the box outside mixing in order to offer fill activated carbon. How does face plate have handle, overleaf is stuck have balata of closed pore fourth sponge in order to assure sealed, back shroud can disassemble, facilitate change activated carbon. 4. Filter paragraph of obstruction caustic break an appointment for 600-1200Pa. 5. Hydrogen of vulcanization of setting of deodorization equipment imports and exports is monitored plan with the appearance that press difference, use at controlling circumstance of observation off-gas treatment and rate of activated carbon saturation.

Above is grand rich environmental protection small the relevant content of the waste gas that in making up what share with everybody how to use activated carbon to handle industry to produce, appears hopes to be able to be opposite you are helped somewhat, the government-owned net that if everybody thinks understanding is more,welcomes everybody to pay close attention to environmental protection of our grand rich continuously about the content of industrial off-gas treatment.
