Abstract

The invention discloses a material with a high-efficiency dust removal function and a production process thereof, belonging to the technical field of environmental protection materials. In the present invention, sodium chloride, hydroxymethyl cellulose, sodium carboxymethyl cellulose and water are mixed to obtain an aqueous phase, and then mixed with styrene, divinylbenzene, azobisisobutyronitrile and a mixed porogen Prepare the organic phase, mix the water phase with the organic phase, add sulfur dispersion liquid and methacryloyloxyethyltrimethylammonium chloride, stir and react to prepare modified polystyrene microspheres, and modify polystyrene Ethylene microspheres are mixed with a mixed dispersion of porous silicon dioxide and graphene oxide, concentrated by rotary evaporation, washed, and dried to obtain a material with high-efficiency dust removal function. The material with high-efficiency dust removal function prepared by the invention has excellent dust removal effect.

Description

technical field [0001] The invention relates to the technical field of environmental protection materials, in particular to a material with an efficient dust removal function and a production process thereof. Background technique [0002] PM2.5 refers to particulate matter with a diameter less than or equal to 2.5 microns in the atmosphere, also known as particulate matter that can enter the lungs. Because of its small particle size, it is rich in a large amount of toxic and harmful substances, so it has a greater impact on human health and the quality of the atmospheric environment. PM2.5 represents the content of such particles per cubic meter of air, and the higher the value, the more serious the air pollution. With the progress of the times, the requirements for the environment are getting higher and higher. [0003] Industrial dust is the main source of PM2.5. At present, the classification basis of industrial dust is different. It can be classified according to the c...

Problems solved by technology

Although the existing dust removal technologies are diversified, each technology has disadvantages that cannot be ignored. The dust removal efficiency of mechanical dust removal technology is too low. In electric dust removal technology, due to the large change of dust specific resistance with temperature, it is necessary to control the temperature. Different particles correspond to different particles. Optimum electric field parameters require multiple adjustments. With the revision of flue gas emission standards, the flue gas after electrostatic precipitator sometimes fails to meet the requirements; although filter dust removal has high dust removal efficiency, the treatment temperature is limited by the filter bag material , not resistant to high temperature, weak in corrosion resistance, unable to deal with acid-base dust-containing gas, not suitable for gas containing dust with strong adhesion or strong hygroscopicity; when the gas volume is large, the structural consumables occupy a large area, and the running resistance is large. The operating cost is high; the mud sediment and waste water produced by the wet dust removal technology need to be treated, the dust recovery is difficult, anti-corrosion measures need to be taken when dealing with corrosive gases, anti-freezing is required in low-temperature areas, and secondary pollution is easy to occur; and the new composite dust removal technology is compared Large, and equipment maintenance costs are high
