With the continuous development of fibrous materials, the material, structure, filtering mechanism, and filtering method of dust removal filter materials have been studied in large quantities. The efficient dust removal of the bag dust collector has promoted the development of fiber dust filter materials into the peak. With the advancement of material technology and the proposal of the "double carbon" strategy, the single dust removal function filter material can no longer meet the requirements of complex operating conditions, and the development of functional filter materials has set off a wave.

Dust Deposit Nitrome/Dispel Evil British Integrated Filter Filter

The filter material of the dust removal denitration is loaded to the surface or inside of the dust removal filter material to obtain the denitration catalytic activity. Due to the high temperature resistance of metal fiber and ceramic fiber filter and filter pipes, it can tolerate the roasting temperature of the front drive body of the SCR denitration catalyst.

At present, more domestic research units and enterprises have carried out research on the dust nitrics of conventional fiber dust filter bags. The renovation catalyst activity of laboratory testing can reach 90%, and the actual trial is more than 60%. Compared with international companies such as Gore, the development of domestic dust removal and denitrification filtering materials is relatively slow. At present, the actual application of dust removal denitration filter materials is mostly demonstration engineering. Its denitration catalytic efficiency, low temperature reaction temperature control, catalyst anti -poisoning and other performances are still breaking through. Similar to the mechanism of the filter material of dust removal and nitritization, the combination of dust removal of the two evils and British integrated filter materials is mainly used to deal with the integration of dust particles in the fields of waste incineration and the two evil English substances.

Anti -static filter material and fire flame retardant filter material

On the occasion containing Mars or with explosive dust, it may cause bright fire or explosion under static electricity, and the filter material needs to be anticidal, flame retardant, and even fire prevention. For a long time, the flame retardant arrangement of filter material usually uses the method of impregnation flame retardant, and the performance of the flame retardant directly determines the flame retardant effect of the filter material. In addition, the use of flame retardant fibers to make filtering materials is also one of the ways to obtain flame retardant performance.

The anti -static consolidation of the filter material is similar to the flame retardant finishing. One is to obtain the anti -static performance by the method of impregnating antistatic agents; the other is to use conductive fiber to make the noodles of the filter material and directly transfer the static charge generated by the dust filter material to directly transfer the filter material. Third, the anti -static base cloth containing metal wire is used to make the filter material obtain the resistance of the electrostatic.

Refusal oil -proof filter material

Water refusal oil -proofing is one of the most common functional collation in bag dust removal filter materials. In many cases, the water in the flue gas is large. Once the water steam is condensed or exposed on the surface of the filter bag, the dust particles are easily adhered to the surface of the filter bag, which is not easy to remove, which will cause the filter bag to paste. In addition, water steam at high temperature will accelerate the hydrolysis reactions of some fibers. When the industrial furnace kiln, it will use kerosene or diesel to bare, and some oil -containing substances are also available in certain operating conditions. Even if the filter material is pre -applied, the oil -proof of the filter material cannot be ignored. At present, the water -resistant oil -proof collation of dust filter materials mainly uses impregnated water -resistant oil -proof agent.

Other functional filter materials

The dust removal filter material belongs to the textile category, and the functional collation of the dust filter material borrows the post -collation process of textiles. Ultra -wear -resistant filtering material, glazed filter material, dust sulfur nitrate intgrade, VOCS filtering material, energy -saving carbon reduction filter material, high -efficiency low -resistant filter material, intelligent monitoring filter material, etc. are still being proposed, developed , Promotion.
