This is an adsorption tower using non-photocatalysis coated activated charcoal as the dust collector, which the limited adsorption capacity of the former system is improved by the decomposition and elimination effect of non-photocatalysis.
Non-photocatalysis : Different from photocatalysis, this is a catalysis that decomposes and eliminates poisonous gas by reacting to oxygen and moisture in the air without light.
Paint mist adsorption.
Part of the organic compound decomposed.
Atmosphere
Oxygen and moisture in the air collide with the catalysis to make superoxide radical (•O2-) and Hydroxy radical (•OH). And they react to VOC to decompose organic compounds (to convert to CO2 & H2O).
Treatment System Stage 1 (VOC Adsorption) → Stage 2 (VOC Decomposition/Elimination) → Stage 3 (VOC Re-adsorption)
General activated charcoal shall be replaced shortly for its adsorption ability decline due to adsorbed VOC increase, while the new material activated charcoal shows replacement efficiency by its constant decomposition and elimination of adsorbed VOC.
