Photocatalyst powder composite deodorizing-type adsorption filtering agent and manufacturing method thereof

Abstract

The invention discloses a photocatalyst powder composite deodorizing-type adsorption filtering agent which is characterized by being prepared from the following raw materials, by weight, 55-65 parts of rectorite, 24-35 parts of diatom ooze, 10-14 parts of soda lime, 1-2 parts of magnesium sulfate, 4-8 parts of a photocatalyst powder, 3.4-3.8 parts of rough-hole spherical silica gel, 2-3 parts of iodine bromide, 0.6-0.9 part of sodium dimercaptosuccinate, 5-7 parts of an epoxy resin emulsion, 6-8% of a hydrogen peroxide solution and a proper amount of water. According to the invention, rectorite, diatom ooze and soda lime are used as raw materials, and iodine bromide, the epoxy resin emulsion and the like are used along with the raw materials. Through a physical and chemical modification method, the photocatalyst powder is loaded on the surface of rectorite. Thus, organic pollutants can be decomposed into carbon dioxide and oxygen so as to reduce harmful substances adsorbed on rectorite and prolong service life of the adsorption filtering agent. The prepared adsorption filtering agent has advantages of rough and hard surface, large specific surface area, high porosity, good adsorption filtering performance and low cost. The adsorption filtering agent can release negative oxygen ions so as to effectively remove foul smell of exhaust gas and purify the air.

Description

technical field [0001] The invention relates to the technical field of adsorption filter materials, in particular to a photocatalyst powder composite deodorizing adsorption filter and a preparation method thereof. Background technique [0002] With the rapid development of industrialization, the problem of air quality is becoming more and more serious. Especially in recent years, smog has seriously threatened people's health across the country, and the side effects caused by it have become increasingly serious. The culprits are domestic building materials, chemicals, For the smoke and dust discharged from kiln heads and kiln tails, calcium carbide furnaces, ferroalloy furnaces, etc. in metallurgical industries, the most commonly used dust removal equipment is the bag filter. The bag filter is a dry dust filter device. After the filter material is used for a period of time, due to effects such as screening, collision, retention, diffusion, and static electricity, a layer of d...

Problems solved by technology

However, in the actual operation process, the use of the first layer is not enough, resulting in low dust removal effect and serious wear and corrosion of the filter material after long-term use. There is an urgent need for an adsorption filter with high efficiency and multiple functions to be sprayed on the filter before the dust collector starts to work. The surface of the material is used as the first layer, which can not only improve the dust removal effect of the dust collector, but also filter and absorb the harmful exhaust gas discharged.
