Abstract
The invention discloses an adsorption filtering agent capable of efficiently adsorbing hydrogen sulfide. The invention is characterized in that the adsorption filtering agent is prepared from the following raw materials, by weight, 15-25 parts of brucite, 50-60 parts of wheat straw, 20-30 parts of ox bone, 3.8-6.2 parts of nanometer titanium dioxide, 0.5-0.8 part of cetyl trimethyl ammonium bromide, 1-3 parts of urea, 5-8 parts of steel fiber, 6-10 parts of a vinyl acetate-acrylic emulsion, 0.2-0.4 part of potassium polyacrylate, 0.9-1.1 parts of guar gum and a proper amount of water. According to the invention, wheat straw and ox bone are used as raw materials, and brucite and the like are used in cooperation. Through a physical and chemical modification method, nanometer titanium dioxide is loaded on the surface of the adsorption filtering agent so as to decompose organic pollutants into carbon dioxide and oxygen and prolong service life of the adsorption filtering agent. 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. By spraying the adsorption filtering agent onto a filter material, hydrogen sulfide gas can be adsorbed efficiently and flue gas can be purified.
Description
Technical field
The present invention relates to absorption filter agent field of material technology, be specifically related to a kind of can the absorption filter agent and preparation method thereof of efficient adsorption hydrogen sulfide.
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.
