Abstract

The invention discloses an adsorbent composition for flue gas treatment during waste incineration and a preparation method thereof. The adsorbent composition is prepared from the following raw materials in parts by weight: 8-12 parts of modified nano calcium carbonate, 5-10 parts of alum, 15-25 parts of zeolite molecular sieve, 20-30 parts of red mud, 10-15 parts of manganese mine tailings, 1-3 parts of zirconium dioxide, 6-10 parts of urea, 10-18 parts of polyacrylamide and 3-5 parts of polymethyl acrylate. The adsorbent composition disclosed by the invention not only can adsorb heavy metal in flue gas during waste incineration, but also can adsorb pollutants such as HCl, HF, SO2 and dioxin, so that the flow of flue gas treatment during the waste incineration is simplified, and the operating cost for the flue gas treatment during the waste incineration is lowered.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an adsorption composition for waste incineration flue gas treatment and a preparation method thereof. Background technique [0002] With the improvement of people's living standards and the rapid increase of urban population, there are more and more industrial and domestic garbage, and the environmental pollution caused by garbage is becoming more and more serious. Some cities have been surrounded by garbage, which has become a major problem for local governments. At present, the treatment methods of municipal solid waste mainly include landfill, incineration and composting. Among them, the use of incineration to treat domestic waste has the advantages of volume reduction, volume reduction, harmlessness, and heat value recovery and utilization. At present, incineration power generation is popular and advocated by the country. Waste incineration power generation can not ...
