Problems solved by technology

The key factors affecting the service life of activated carbon are the total amount of harmful substances in the environment and the desorption frequency. When the gap is filled, it needs to be exposed to the sun to increase the service life. When the ambient temperature and pressure change, the adsorbed harmful substances are easy Precipitation occurs, resulting in low adsorption efficiency of activated carbon, resulting in secondary pollution, resulting in failure to purify the air. At the same time, the adsorption effect of activated carbon materials on gas fluorine is poor, and on formaldehyde and VOC S The adsorption effect is not very ideal

Abstract

The invention discloses purifying particles filled in a filter screen, and relates to the technical field of air purifying. The purifying particles comprise the following components in parts by weight: 70-80 parts of a restraining adsorbent, 60-70 parts of a photocatalyst, 20-30 parts of potassium permanganate, 20-30 parts of a surfactant, 20-30 parts of a herbal mixture, 10-15 parts of a filling agent, 5-10 parts of a formaldehyde-cleaning agent, 2-8 parts of a dispersion agent and an appropriate amount of deionized water. The purpose of removing harmful gas is achieved by combination of two methods of adsorption and catalytic oxygenolysis. The removal efficiency of the purifying particles is higher than that of a pure physical adsorption material. Therefore, the purifying particles are suitable for being used as a substitute material for activated carbon in an indoor air purifier.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to purification particles filled in a filter screen. Background technique [0002] At present, the adsorption materials for household air purifiers are generally various types of activated carbon. The adsorption principle of activated carbon is physical adsorption, relying on its internal developed pore structure and large specific surface area. The key factors affecting the service life of activated carbon are the total amount of harmful substances in the environment and the desorption frequency. When the gap is filled, it needs to be exposed to the sun to increase the service life. When the ambient temperature and pressure change, the adsorbed harmful substances are easy Precipitation occurs, resulting in low adsorption efficiency of activated carbon, resulting in secondary pollution, resulting in failure to purify the air. At the same time, the adsorption effect of activ...
