Comprehensive metal oxide modified diatomite adsorption filtering agent and preparation method thereof

Abstract

The invention discloses a comprehensive metal oxide modified diatomite adsorption filtering agent which is characterized by being prepared from the following raw materials, by weight, 60-65 parts of diatomite, 20-30 parts of flue dust, 10-14 parts of activated aluminium oxide, 3.7-5.9 parts of nanometer titanium dioxide, 2.4-3.6 parts of nanometer calcium carbonate, 2-4 parts of copper oxide, 1-3 parts of iron chloride, 1.3-2.7 parts of potassium ferrate, 3-5 parts of terpineol, 0.2-0.4 part of sodium dodecyl benzene sulfonate, 6-8 parts of syrup and a proper amount of water. According to the invention, diatomite and flue dust are used as raw materials, and activated aluminium oxide, copper oxide and the like are used in cooperation. Through a physical and chemical modification method, nanometer titanium dioxide is loaded on the surface of diatomite so as to decompose organic pollutants into carbon dioxide and oxygen. Thus, harmful substances adsorbed on diatomite are reduced, and service life of the adsorption filtering agent is prolonged. 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. When sprayed on a deduster filter material, the adsorption filtering agent also has a waterproof effect.

Description

technical field [0001] The invention relates to the technical field of adsorption filter materials, in particular to a comprehensive metal oxide modified diatomite 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...

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.
