SCR technology is  a recation at use of  the denitration catalyst at a certain temperature(270-400 degree),that NOX in the flue gas mixed with  ammonia gas from the reducing agent  supply  the system after the occurence of the selective  catalytic reduction reaction of nitrogen and water ,thereby  reducing NOX emissions , and reducing smoke  pollution to the environment. The  chemical eauation  for a selective catalytic reaction process is : 4NO+4NH3+O2→4N2+6H2O           6NO2+8NH3→7N2+12H20 NO+NO2+2NH3→2N2+3H20

The melting temperature of PPS is as high as 285℃。PPS felts is sensiti to oxygen under high temperature.

Yuanchen manufactures a wide range dust collector filter cages to fit all baghouse makes and models. We can also manufacture uncommon and specialized cage designs as required.

Bag filters are in general frequently used for dust removal in industrial applications. We make filter bags to fit most styles and types of bag houses and other dust collection systems.

This Pleated Filter Bag can significantly increase the air volume of existing dust collectors to increase production capacity and greatly improve the collection efficiency of dust collectors, especially PM2.5 and PM10 ultrafine dust. It can also reduce energy consumption and maintenance costs, extend the service life. It can be provided in different specifications. 

Needle felt is a kind of non-woven filter fabric specially used for dust collector filter bags. It is a major filter material for industrial air filtration and dust removal. The needle felt is made of randomly arranged fibers needle punched on the scrim fabric, after that the fibers are close-knitted to form a tortuous three-dimensional stereo-structure, which is different from the traditional woven filter cloth composed of warp and weft yarns. It makes dust particles adhere to the surface of the filter material and form an initial layer of dust ( Filter cake), with the remarkable characteristics of small pore size, high filtration efficiency and low air resistance, greater air permeability and excellent dust particle capture.

Our Polyimide P84 Filter Bag is 100% made of P84 polyimide fiber which has extraordinary filter and heat resistance function.  It is widely used in waste innceneration.

Long-term temperature resistance of 260℃, instantaneous temperature resistance of 300℃, is a kind of filter material with excellent high temperature resistance, acid and alkali resistance. It has various characteristics as a high-performance fiber; it can resist a variety of acids, alkalis and Chemical corrosion of oxidizer; has good hydrolysis resistance; typical applications are Cement,Waste Incineration.

Bag filters are in general frequently used for dust removal in industrial applications. We make filter bags to fit most styles and types of bag houses and other dust collection systems. Filter bags come in a wide range of fabrics, coatings, finishes, sizes and configurations.Medias are available in various fabric weights and treatments such as singed, glazed, PTFE membrane, acid and alkali resistance and Oxidation resistance.
