Production device and process of PPS filter bag with combined removal function of combined pollutants

Abstract

The invention discloses a production device and process for a PPS filter bag with a combined removal function of combined pollutants. The production device comprises a nitric acid solution pool, a circulating spray tower, a sodium dodecyl sulfate solution pool, an active component salt solution pool, a three-stage drying box, a PTFE solution tank and a power mechanism. The three-stage drying box is composed of a low-temperature drying box, a high-temperature drying box and a medium-temperature drying box. The production device and process for a PPS filter bag with a combined removal function of combined pollutants disclosed by the invention effectively combines the dipping-calcining method with the traditional production process of the filter bag, so as to realize the direct production transformation from the PPS raw material to the pollutant combined removal function filter bag. The innovation cost of the existing industrial production mode is greatly reduced, and at the same time, the combined removal of the high-efficiency flue gas multi-component pollutant of the PPS filter bag is realized. The flue gas purification process is simplified and the cost of pollutant removal is reduced.

Description

technical field [0001] The invention relates to the technical field of production of functional PPS filter bags, in particular to a production device and process of a PPS filter bag with combined pollutant removal function. Background technique [0002] Low-temperature denitrification combined with mercury removal composite PPS functional filter material is an innovative and sustainable technology integrating dust removal, denitrification and mercury removal, so as to achieve the goals of simplifying the treatment process and reducing environmental protection investment. The principle is that the flue gas passes through the tail bag filter. 99.9% of the dust on the surface of the filter material is removed, while the pollutants NO and Hg 0 As the flue gas passes through the filter membrane on the outer surface of the filter bag, under the catalytic action of the catalyst on the surface of the PPS filter bag, NO and NH 3 Converted to harmless N by SCR catalyzed oxidation rea...

Problems solved by technology

[0003] At present, the commonly used PPS cloth bag in the market only has the function of dust removal; in the invention patent with the application number CN201610874980.7, its specific technical solution includes: a processing technology of oil-proof needle-punched filter bag, which is through acupuncture→5- 35% potassium permanganate modification → 360-400 ℃ hot washing → 0.5-12% fluorine-containing oil repellent treatment agent treatment → 0.5-8% cross-linking agent impregnation → packaging process Improve the existing process to achieve Simplify the process, but the main problem is that it has made great changes to the existing traditional treatment process, put forward strict requirements for industrial transformation, and cannot adapt to the existing vast PPS bag production market, and this invention still fails to propose new pollutants for PPS bags Removal of functions cannot fundamentally reform the existing PPS bag market
