The foul odor gases that occur in industrial production can be collected through exhaust gas collection (ventilation and local ventilation) and then treated using exhaust gas treatment processes. We usually use some common deodorization methods, such as the following. The deodorant is a dry flow method for deodorization.

The activated carbon adsorption method is to fill the adsorption tower with activated carbon, capture exhaust gas molecules through porous activated carbon, and purify the exhaust gas. Due to the drying requirements of activated carbon, it is not suitable for use in industries with high humidity. Photocatalytic treatment of exhaust gas technology is a technology that Anjuke has experienced for many years of research and practical experience, and is the first to introduce and apply on a large scale in the field of industrial exhaust gas purification in China. A series of industrial photocatalytic organic waste gas purification equipment that has been continuously improved.

Chemical deodorants use oxidation, reduction differentiation, neutralization reaction, addition reaction, condensation reaction, ion exchange reaction, etc. to transform the foul smelling substances into odorless substances and eliminate odors.

Oxidative deodorant

NaClO、 Chlorine and other oxidants oxidize organic sulfur and amines in the odor into compounds with lighter odor or higher solubility, and then absorb and purify them with acid and alkali.

Salt compounds

Using salt compounds as deodorants, such as divalent iron ions and ascorbic acid, to suppress oxidation and react with foul smelling substances such as ammonia and mercaptan to turn them into odorless substances; The coordination of trivalent iron derivatives and metal complexes reacts with thiols or sulfur to exchange and convert odorous substances into odorless substances.

Acid and alkali preparations

Using acidic or alkaline substances as deodorants, such as zinc oxide and hydrogen sulfide, can cause non catalytic gas-solid reactions and remove hydrogen sulfide gas from the air; Flavonoids and tannic acid, as well as other wood essential oil components, undergo inclusion, neutralization, and addition reactions to remove odorous substances
