Sheet material integrating filtering dust removal and catalytic denitration, and manufacturing method thereof

Abstract

The invention discloses a sheet material integrating filtering dust removal and catalytic denitration, and a manufacturing method thereof, wherein the sheet material comprises a base sheet capable offiltering flue gas, and a catalyst for denitration is attached to the base sheet. The manufacturing method comprises: 1, mixing polyphenylene sulfide (PPS) fiber and polytetrafluoroethylene (PTFE) fiber to prepare a base sheet; 2, preparing a viscous filtering material from part of the base sheet; 3, preparing nano-scale catalyst powder from the viscous filtering material, Mn, Ce, Zr, Ti, Fe, Cu and other elements; 4, preparing a manganese-based oxide emulsion from the prepared powder; and 5, immersing the base sheet into the manganese-based oxide emulsion to prepare the sheet material. According to the present invention, the sheet material is placed into the cloth bag dust removing device, such that the flue ash in the industrial flue gas can be filtered while the industrial flue gas is subjected to catalytic denitration treatment, the occupation problem is avoided, the investment is low, and the promotion application of the cloth bag dust removal is easily achieved.

Description

technical field

[0001] The invention relates to a product for denitrification and dedusting of industrial flue gas and a manufacturing method thereof, in particular to a chip integrating filtering dust removal and catalytic denitrification and a manufacturing method thereof. Background technique

[0002] Nitrogen oxides (NOx) and fine particulate matter are the main pollutants in the atmosphere. NOx is the main cause of acid rain, photochemical smog and greenhouse effect, while fine particulate matter below PM10 is poisonous and harmful to human body. Nitrogen oxide and fine dust particles are also important precursors of smog. Cement plant is an important emission source of nitrogen oxides and dust, and its flue gas pollution has been paid more and more attention. The current nitrogen oxide treatment technologies mainly include low nitrogen combustion, SNCR, SCR and so on. Among them, the mature and efficient denitrification technology is mainly (selective catalytic reduc...

Embodiment Construction

[0066] Such as figure 1 As shown, this embodiment provides a sheet material that integrates dust removal by filtration and catalytic denitrification, including a substrate 1 that can filter flue gas, and the substrate 1 that can filter flue gas is densely covered with dust filter ventilation holes 3. A catalyst 2 for denitrification is attached to the substrate 1 which can filter flue gas.

[0067] In this embodiment, since the base sheet capable of filtering flue gas is densely covered with dust filter ventilation holes, and the substrate capable of filtering flue gas is attached with a technical means for denitrification catalyst, the sheet material is put into the bag filter Inside, while filtering the soot in the industrial flue gas, it also performs catalytic denitration treatment on the industrial flue gas. Moreover, it avoids the problem of occupying land and requires less investment, which is conducive to the popularization and application of bag dust removal. The fla...
