High-temperature adsorption filtering agent capable of absorbing carbon dioxide and preparation method therefor

Abstract

The present invention discloses a high-temperature adsorption filtering agent capable of absorbing carbon dioxide. The high-temperature adsorption filtering agent capable of absorbing carbon dioxide is characterized by being prepared from the following raw materials in parts by weight: 63-70 parts of barite, 7-11 parts of hydrotalcite, 10-20 parts of coal gangues, 7-9 parts of seaweed carbon fibers, 5-9 parts of nanotitanium dioxide, 1.4-3.5 parts of lithium zirconate, 1-3 parts of manganous nitrate, 2-4 parts of sodium chlorite, 0.8-1.5 parts of cyclopropylboronic acid, 3-5 parts of coal tar, 6-8 parts of a polytetrafluoroethylene emulsion solution and an appropriate amount of water. According to the high-temperature adsorption filtering agent capable of absorbing carbon dioxide, by taking barite as a raw material which is matched with hydrotalcite, coal gangues, lithium zirconate and the like, nanotitanium dioxide is loaded on the surface of the barite through physical and chemical modification methods to decompose organic pollutants into carbon dioxide and oxygen, so that harmful substances adsorbed onto the barite are reduced, and the service life of the adsorption filtering agent is prolonged. The prepared adsorption filtering agent is coarse and hard in surface, large in specific surface area, high in porosity, good in adsorption and filtration capacity and low in cost, and moreover, carbon dioxide can be efficiently absorbed, so that the discharge rate of carbon dioxide is reduced.

Description

technical field [0001] The invention relates to the technical field of adsorption filter materials, in particular to a high-temperature adsorption filter capable of absorbing carbon dioxide 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, ...

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.
