Chemical filter is a new type of air purification equipment for treating malodorous, toxic and corrosive gases in the air.

Working principle: air is purified mainly by physical adsorption and chemical reaction. Physical adsorption relies on the microporous structure of adsorption materials such as activated carbon, and adsorbs pollutant molecules through van der Waals force. Chemical adsorption means that activated carbon and other filter materials are impregnated with chemical reagents, which react with acidic or alkaline gases to convert them into harmless substances. Some filter materials can also catalyze the decomposition of harmful gases such as ozone and hydrogen sulfide by adding catalysts.

Product features: the filter material is often designed with filter core lock cap, which has good sealing performance, and the filter cartridge can be free of metal contact. Usually made of PVC, it can withstand chromic acid solution and various acid-base liquids, and it is easy to operate.

Filter material types: mainly alumina particles, activated carbon particles and mixed particles. Alumina particles can be mixed with different impregnants for different target gases; Activated carbon particles are made of coal, wood, etc., with a large number of pores and large surface area, and the adsorption effect is good; Mixed particles combine the characteristics of different particles in physical adsorption and chemical absorption.

Application area

Public places: it can be used in airports, hospitals, office buildings, etc., and can effectively remove the odor in the air. For example, it can improve the air quality in the wards of patients with respiratory diseases in hospitals, and at the same time has the advantage of energy saving.

Cultural relics protection sites: museums, archives, libraries and other places can remove sulfur oxides, nitrogen oxides and other polluting gases in the air and prevent cultural relics, archives and other collectibles from being eroded and destroyed.

Industrial field: the central control room of chemical, petrochemical, steel and other enterprises can protect precision instruments from corrosive gases. In semiconductor and microelectronics manufacturing enterprises, "molecular pollutants" can be removed, product quality can be improved, and personnel health can be guaranteed. In addition, it can also be used to treat industrial waste gas. For example, garbage treatment plants can remove odor gas through chemical filters.

Laboratory and laboratory animal room: the chemical gas generated by reagents can be treated in the laboratory to ensure the safety of the experimental environment and accurate data. Laboratory animal rooms can reduce odor, improve the quality of laboratory animals and protect the atmospheric environment.

Water treatment field: it can be used for filtering all kinds of wastewater, such as heavy metal wastewater, wastewater containing suspended substances in chemical production, etc., and can also be used for filtering river water and groundwater.
