Wire Cages are professionally manufactured, constructed from galvanized or stainless steel and welded for structural stability.

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.

FMS material introduction alkali-free glass fiber,aramid fiber,p84 fiber   FMS needle felt is made of alkali-free glass fiber,aramid fiber and p84 fiber by blending and laminated needling.It is a high temperature and efficient filtration material with three-dimensional pore structure.

The chemical name of PPS is polyphenylene sulfide. It is a white material with excellent thermal stability. Although it will burn when it is placed in a flame, the combustion will stop immediately when the flame is removed. It will show a yellow-orange flame when it burns, and a trace of black will be generated. Soot does not fall off the burned material, and forms residual coke, showing low flame spread and smoke density. The limiting oxygen index is 34-35. The most commonly used fineness is: 2.2 dtex. Other finenesses are: 1.1 dtex 1.7 dtex 3.0 dtex and so on. The most commonly used lengths: 51mm and 60mm. The working temperature is 130～160℃, the short-term working temperature is 190℃, and the melting point is 285℃. In addition, the oxygen content of the fiber should be less than 8% during normal use. The higher the oxygen content, the use temperature should decrease accordingly.

At present, there are two main manufacturing processes for filter bags: one is sewing, which is used for filter bags made of PPS, NOMEX, P84, PTFE or surface coating treatment. The other is heat welding, which is used to manufacture filter bags with PE, PP, acrylic, PPS, etc. as raw materials. The use of heat welding improves the efficiency and performance of filter bag manufacturing.

Denitration in different industries is also being carried out one after another. The temperature, ash and alkali metal content of their flue gas are very different. The alkali content of flue gas in many industries is much higher than that of pulverized coal power generation denitrification. Therefore, it also poses a new challenge to the problem of alkali metal poisoning of the SCR vanadium-based denitration catalyst. Especially in industries such as cement kilns, iron and steel sintering machines, coking plants, alumina clinker kilns and biomass boilers, and high-alkali coal power generation, it is necessary to attach great importance to the poisoning risk of alkali metals in flue gas denitration to denitrification catalysts.
