The VOC deodorizing equipment is a kind processor in the earth which resolved VOC gas by using superheated-steam gas for desorption
The deodorizing organic solvent can be efficiently absorbed. It uses ceramic honeycomb activated carbon which is a patent product and the absorption time can be about 30% abridged more than a granular activated carbon.

|
|
After absorption solvent (VOC) by ceramic honeycomb activated carbon,it resolves solvent(VOC) with superheated-steam and processing gas,there is a release into the atmosphere.
As for the absorbing agents,there is a self-renewal with super heated-steam.

1.By using ceramic honeycomb activated carbon for the absorption of the solvent (VOC) absorption and the desorption or stench gas because the absorption surface area is big and moreover there are few pressure loss of the processing gas capacity.the facilities become compact and running cost is reduced.
2.To use superheated-steam (300℃) when making desorption solvent(VOC) from ceramic honeycomb activated carbon VOC is resolved by H2O and CO2.
3.When using a granular activated carbon for the absorption,there is possibility of the spontaneous combustion of the activated carbon main unit by the occurrence of the heat-of-adsorption but as for ceramic honeycomb activated carbon,because the exothermicaction very good ,the spontaneous combustion becomes the safe facilities which don’t happen.
4.Ceramic honeycomb activated carbon can reduce the desorption time of VOC more by about 30% than a granular activated carbon.

●Stench compatible when the exhaust is a low concentration (about tens of ppm)
●it absorbs stench gas by ceramic honeycomb activated carbon.
As for ceramic honeycomb activated carbon,there is a self renewal in superheated-steam.

●It is safe in the fire-resistant and moreover the water-insoluble.the surface area of the ceramic honeycomb activated carbon is 4 times of the granular activated carbon,and the pressure loss is 1/10 and as for them of effective adsorption and desorption are possible.
●It is excellent about the absorption of poisonous gas too,and it is excellent about the gas absorption of the organophosphorus compound type which was supposed to be difficult to absorb conventional activated carbon and charcoal such as the Formaldehyde Toluene and IPA(Isopropyl alcohol) and so on,too.
