Dust filter bags

PTFE Needle Punched Felt Filter Bag for Waste Incineration

Since the white fiber is produced by the film splitting method, the dispersion in fineness is relatively large, generally from 2dtex to 10dtex. The brown fiber is wet-spinned, so the fiber fineness is relatively fixed. At present, it is 3.3dtex in foreign countries, and the single yarn strength is generally above 4dtex in China. The length is generally 51mm~75mm.

The melting point of PTFE is 327 °C, and it can be used for a long time at a high temperature of 260 °C, and the instantaneous use temperature can exceed 300 °C. PTFE cannot burn, and its limiting oxygen index reaches 95%.

The strength is low and the breaking elongation is small. The breaking strength of the imported brown fiber is only 1.9cn/dtex, while the strength of the white imported fiber basically does not exceed 4cn/dtex. The friction coefficient is low, so the dust is easy to fall off on the surface of the filter material. The surface tension of the fiber is large, and it has good water repellency. The fiber is finer, the filtration efficiency is average, and the filter material has a weight of 750-800g. The textile performance is not good, the cohesive force is low, and static electricity is easily generated in the fiber spinning process.

2. We pay attention to following processing matters:
(1) Precise design required size of the filter cloth for filter bag parts, the filter cloth will larger than the actual amount design size, to leave a spare for weaving.
(2) To choose the right filter bag accessories, specifications and check its quality. The filter bag accessories should match the filter bag quality requirements.
 (3) We make the filter bag line drawing, cutting, sewing on automatic production line. When the filter bag need manual processing, we will open it on the operation platform, and with certain pulling force to keep it is flat.
(4) We keep the strict processing quality standards, according to design drawings and operation process. Our worker meet the requirements of tooling and clothing , no smoking.
 (5) We have the responsible for the processing of products, and examines, waste, residue, defective goods in the beginning.

Honeycomb Catalyst
Coal-Fired Boilers Honeycomb SCR Denox Catalyst
SCR technology is a reaction at use of the denitration catalyst at a certain temperature (270-400℃),that NOX in the flue gas mixed with ammonia gas from the reducing agent supply system after the occurrence of the selective catalytic reduction reaction of nitrogen and water ,thereby reducing NOx emissions,and reducing smoke pollution to the environment.
P84 Dust Filter Cloth
Dust Collector P84 Filtering Material
Long-term temperature resistance 230℃, instantaneous temperature resistance 260℃; It is made of a polycondensation polymer, which is not resistant to hydrolysis; the cross section is in the shape of a trilobe. Due to the increased surface area of the single fiber, it can effectively trap particles, and the filtration accuracy is high; It is a non-thermoplastic fiber, and has stronger abrasion resistance to pulse cleaning than glass fiber. Therefore, P84 can be used instead of glass fiber or mixed use under conditions that require good abrasion resistance. Its anti-oxidation performance is better than PPS filter media, but its acid resistance and hydrolysis resistance are slightly worse, and its alkali resistance is poor. It is suitable for use in the treatment of kiln flue gas with low sulfur content.
