Abstract

The invention belongs to the field of air purification and in particular relates to an indoor gaseous pollutant purifying filter material. The indoor gaseous pollutant purifying filter material comprises the following components in percentages by mass: 0-20% of an alkaline porous silicon-calcium composite material, 20-30% of potassium permanganate-immersed activated aluminum oxide, 5-20% of acidic modified activated carbon, 15-25% of coconut shell activated carbon, 15-40% of coal activated carbon and 5-25% of a carbon dioxide filter material. The material provided by the invention avoids a desorption phenomenon, can relatively comprehensively purify gaseous pollutants in air in a pointed manner, is suitable for purifying air in various environments, and overcomes the problem of discomfort of a human body as the concentration of carbon dioxide is raised due to movement of breath of personnel in a closed space.

Description

technical field [0001] The invention belongs to the field of air purification, in particular to a filter material for purifying indoor gaseous pollutants. Background technique [0002] Existing methods for removing and purifying gaseous pollutants used in common household air purifiers: [0003] 1. Use ordinary activated carbon and similar porous structure materials for physical adsorption, compress gaseous pollutants into liquid and store them in the porous structure, and achieve the effect of air purification. [0004] 2. The porous material impregnated with a strong oxidant is used to oxidize and decompose some gaseous pollutants in the air to achieve the effect of air purification. [0005] The disadvantages of these approaches are: [0006] 1. After working for a period of time, after reaching the maximum load, desorption will occur, that is, the gaseous pollutants in the air will return to the air, causing secondary pollution. [0007] 2. There is no very comprehens...
