Recyclable environmentally friendly adsorption filtering agent and making method thereof

Abstract

The invention discloses a recyclable environmentally friendly adsorption filtering agent, characterized by comprising the following raw materials by weight: 70-80 parts of sepiolite, 6-9 parts of plant carbon black, 10-14 parts of calcite, 5-7 parts of zeolite molecular sieve, 4-6 parts of nano-TiO2, 2-4 parts of chitosan, 1-2 parts of peroxide sodium, 3-4 parts of ferric nitrate, 0.4-0.8 part of titanium trichloride, 7-10 parts of waterborne fluorocarbon emulsion, and right amount of water; the sepiolite as a raw material is mixed with the plant carbon black, the calcite, zeolite molecular sieve, nano-TiO2TiO2, and the like, the nano-TiO2TiO2 is loaded on to the sepiolite surface by physical and chemical modification method, and organic pollutants are decomposed into carbon dioxide and oxygen, so that harmful substances absorption on sepiolite is adsorbed, the service life of the adsorption filtering agent is prolonged, the prepared adsorption filtering agent is rough and hard in surface, large in specific surface area, high in porosity, good in adsorption and filtration performance, high in performance cost and low in cost, can effectively absorb carbon dioxide, and can be used repeatedly.

Description

technical field [0001] The invention relates to the technical field of adsorption filter materials, in particular to a recyclable environment-friendly adsorption filter and a manufacturing 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 dust accum...

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.
