Integrated multifunctional smoke purifying filter element

Abstract

The invention belongs to the field of environmental protection, and relates to an integrated multifunctional smoke purifying filter element. The integrated multifunctional smoke purifying filter element comprises a component A and a component B, wherein the component A comprises 30 to 55 parts of diatomite, 5 to 8 parts of aluminum powder, 10 to 25 parts of clay, 10 to 18 parts of calcium carbonate, 10 to 30 parts of manganolite, 13 to 33 parts of bitumite, 12 to 16 parts of iron ore, 5 to 11 parts of titanium ore, 1 to 5 parts of nickel powder and palladium powder, and 10 to 2 parts of silica sol; the component B comprises 20 to 30 parts of active carbon, 20 to 30 parts of manganese dioxide, 2 to 6 parts of pore-forming agent, 1 to 2 parts of curing agent, 10 to 20 parts of No. 500 cement, 1 to 2 parts of water impregnating agent and 10 to 18 parts of water. By adopting the integrated multifunctional smoke purifying filter element, different contaminants in the smoke are concentrated in a same container to be crossly treated. By adopting the integrated multifunctional smoke purifying filter element, not only is less investment needed, but also the process is simple; a selective catalytic oxidation neutralization absorption method (SCN method) is used for treating the smoke so as to purify the smoke, and the method also can be named as low-temperature treatment method. A product treated by adopting the method is convenient to recycle, secondary pollution and waste can be avoided, income benefit can be created, and the invested capital can be recovered.

Description

technical field [0001] The invention belongs to the field of environmental protection and relates to an integrated multifunctional filter element for flue gas purification. Background technique [0002] At present, the process devices using the traditional honeycomb SCR flue gas purification technology have short service life, generally 2-3 years, single function (only flue gas purification), efficiency lower than 80%, large volume, occupying an area The area is also large, and the system resistance is large. Since the existing technology is a separate processing type, the initial investment in equipment engineering is increased. In the later stage of operation, not only the purification of harmful gases is not complete, but also the utilization rate of dedusting and desulfurization is low; denitrification cannot be recovered, and a large amount of denitrification agent needs to be paid. In order to save costs and cut corners, resulting in incomplete cure, and the discharg...
