Abstract

The invention discloses an air purifying agent. The air purifying agent is prepared from substances as follows: modified silicon dioxide, attapulgite, kaolin, sodium alginate, urea, epoxidized soybeanoil and calcium stearate. Ingredients in the air purification agent are reasonably selected and matched, the finally prepared air purification agent has remarkably improved adsorption purification capability under the joint action of all ingredients, and the removal rate of chemical pollutants in the air reaches 99% or above.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to an air purifier. Background technique [0002] HVAC ducts are commonly used as return air ducts for purification systems, central air-conditioning ventilation ducts, industrial air supply and exhaust ducts, and environmental protection system suction and exhaust ducts. However, the current HVAC ducts do not have good air purification capabilities. With the continuous accumulation of various harmful substances discharged into the air for many years, the air quality has been seriously polluted, and the particulate matter and various toxic and harmful gas pollution in the air have brought serious threats to people's life safety. Whether indoors or outdoors, there are biological pollutants, odor pollutants, chemical pollutants, airborne particle pollutants and so on in the air. Therefore, the polluted air passing through the heating and ventilation pipes will di...
