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
The present invention relates to absorption filter agent field of material technology, be specifically related to high temperature adsorption filtering agent of a kind of Absorbable rod carbon dioxide and preparation method thereof.
Background technology
Along with the fast development of process of industrialization, air quality problems is increasingly serious, especially the healthy of people in nationwide haze serious threat in recent years, the side effect brought thus is also day by day serious, wherein arch-criminal is exactly the flue dust of the discharge such as kiln head and tail, furnace of calcium carbide, ferro-alloy furnace of the industries such as domestic building materials, chemical industry, metallurgy, and cleaner the most frequently used is at present exactly sack cleaner.Sack cleaner is a kind of dry type dust filtration device, after filtrate uses a period of time, due to effects such as sieving, collision, delay, diffusion, electrostatic, one deck dust has been gathered on filter bag surface, this layer of dust is called bonding layer, and in motion process after this, bonding layer has become the main filtration layer of filtrate, rely on the effect of bonding layer, the filtrate that mesh is larger also can obtain higher filter efficiency.But the utilization of bonding layer is abundant not in real-world operation process, cause that dust removing effects is low, the consequences such as erosion corrosion situation is serious after filtrate Long-Time Service, the absorption filter agent being badly in need of a kind of efficient function diversification is sprayed on filter material surface and is used as bonding layer use before deduster is started working, both can improve the dust removing effects of deduster, the harmful exhaust that absorption is fallen to discharge can also have been filtered.
Summary of the invention
