Abstract
The present invention discloses a photocatalyst type adsorption filtering agent capable of efficiently absorbing nitrogen oxide. The photocatalyst type adsorption filtering agent capable of efficiently absorbing nitrogen oxide is characterized in by being prepared from the following raw materials in parts by weight: 58-68 parts of celestite powder, 10-20 parts of clays, 15-20 parts of bamboo charcoal powder, 8-12 parts of polyurethane foaming plastic, 4.7-6.7 parts of nanotitanium dioxide, 0.3-0.7 part of sodium citrate, 0.4-0.6 part of cuprous chloride, 1-2 parts of sodium hydrogen sulfite, 3-5 parts of tea tree oil and an appropriate amount of water. According to the photocatalyst type adsorption filtering agent capable of efficiently absorbing nitrogen oxide the polyurethane foaming plastic has a structural three-dimensional network structure, has more pores and the pore diameters can be adjusted. The titanium dioxide and celestite powder are dispersed in a polyurethane foaming plastic matrix to decompose organic pollutants into carbon dioxide and oxygen, so that 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 further has a good characteristic of adsorbing nitrogen oxide.
Description
Technical field
The present invention relates to absorption filter agent field of material technology, being specifically related to a kind of photocatalyst type can the absorption filter agent and preparation method thereof of efficient adsorption nitrogen oxide.
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
