Adsorption filtering agent with strong wear resistance and filtration effects and preparation method thereof

Abstract

The invention discloses an adsorption filtering agent with strong wear resistance and filtration effects. The adsorption filtering agent is prepared from the following raw materials, by weight, 20-30 parts of furnace slag, 50-60 parts of meerschaum, 10-20 parts of earthworm cast, 3-5 parts of renewable dispersed latex powder, 1-2 parts of lithium hydroxide, 2-3 parts of boric acid, 6-9 parts of plaster fiber, 3-4 parts of nanometer silicon carbide, 3-6 parts of nanometer titanium dioxide, 8-10 parts of bamboo pulp fiber and a proper amount of water. The prepared adsorption filtering agent has advantages of rough and hard surface, large specific surface area, high porosity and good adsorption filtering performance, and is easy to popularize and use. By spraying the adsorption filtering agent prepared by addition of furnace slag, earthworm cast and other ingredients onto a deduster filter material, wear resistance of the filter material can be raised, and service life of the filter material also can be prolonged. The adsorption filtering agent also has a good effect of absorbing various harmful gases and radioactive substances. The adsorption filtering agent has a wide range of application.

Description

Technical field [0001] The invention relates to the technical field of adsorption filter materials, in particular to an adsorption filter with strong wear-resistant filtering effect and a manufacturing method thereof. Background technique [0002] With the rapid development of industrialization, air quality problems have become increasingly severe. Especially in recent years, smog across the country has seriously threatened people’s health, and the side effects brought by it have become increasingly serious. The culprits are domestic building materials, chemicals, At present, the most commonly used dust removal equipment is the bag filter for the smoke and dust discharged from the kiln head and kiln tail, calcium carbide furnace, and ferroalloy furnace in metallurgy and other industries. The bag filter is a dry filter device. After the filter material is used for a period of time, due to the effects of filtering, collision, retention, diffusion, static electricity, etc., a layer ...

AI Technical Summary

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.
