Activated carbon filter is plate type chemical filter, or chemical air filter; Different from the general air filter, activated carbon air filter can remove air pollutants (such as disturbing odor, corrosive gas, toxic gas), effectively improve indoor air quality (IAQ), protect people’s health and improve product quality, widely used in a variety of centralized ventilation systems.

Activated carbon air filter has a very strong adsorption capacity for some harmful inorganic gases of organic materials, which can effectively remove odor and is suitable for all kinds of air conditioning and ventilation systems. In the air conditioning ventilation system, the treatment of odor and air pollution effect is particularly good, can effectively clean the air.

Activated carbon air filter | chemical filter filtration principle:

Activated carbon air filters are selective adsorption of gaseous pollutant molecules, unlike dust filters that mechanically intercept impurities.

Adsorption is the phenomenon of solid material surface to gas or liquid molecules, in which the solid material is called adsorbent, adsorbed material is called adsorbent.

Adsorption can be divided into physical adsorption and chemical adsorption. Physical adsorption mainly depends on van der Waals force, usually at a lower temperature, the process is reversible.

Some gases (such as ammonia, hydrogen sulfide), the adsorption capacity of ordinary activated carbon is limited, at this time, people often carry out chemical treatment to enhance their ability to remove specific pollutants.

Chemical treatment of the adsorption material and harmful gas to produce chemical reaction of adsorption called chemisorption, the process is irreversible.

The adsorption process can be divided into three stages: diffusion of gas molecules to the surface of activated carbon, referred to as external diffusion; Gas molecules in the activated carbon micropore diffusion to the inner surface, referred to as internal diffusion; On the inside surface of the activated carbon, the gas molecules are sucked.

Activated carbon filter | chemical filter applications:

Air filtration in airports, hospitals (such as the wards of patients with respiratory diseases), office buildings and other public places can effectively remove the odor in the air and save energy.

In museums, archives, libraries and other places, the removal of hydrogen sulfur, nitrogen oxides and other polluting gases in the air, protect the collection from destruction.

The central control room of chemical, petrochemical, steel and other enterprises is used to protect precision instruments from corrosive gases.

Semiconductor and microelectronics manufacturing enterprises, remove “molecular level pollutants”, improve product quality, protect personnel health.

In the laboratory animal room to reduce the stench, improve the quality of experimental animals, and protect the atmospheric environment.

General ventilation chemical filter is suitable for comfort central air conditioning system, eliminate low concentration of gaseous pollutants, effectively improve indoor air quality (IAQ), effectively remove body odor, smoke odor; purification
