Polyphenylene sulfide filter bag

The glass fiber expanded yarn filter material is a fabric filter material made of some bulky yarn. Compared with continuous fiber filter cloth, the filtration performance of the bulky yarn filter cloth is obviously improved. Because of its structure, the flow of the continuous fiber filter can hardly pass through the interior of the yarn. It can only pass through the hole in the weft yarn interweave. In order to ensure the permeability of the fabric, the hole of the yarn is generally large. Even if the formation of the powder layer is filtered, the filtration speed can not be too large, otherwise it is easy to filter through. The expansion of the yarn filter cloth can increase the surface area of the dust, prolong the time of collecting dust, and be beneficial to the fine particles. 

The structure of the dust filter is loose, the void ratio is large and the covering capacity of the puffed yarn is strong, and the airflow passage in the interweaving of the weft yarn and the weft yarn can be covered so that the puffed yarn filter cloth passes through. Filtration resistance is smaller, filtration efficiency and filtration speed are higher. The filtration speed of the bulky yarn filter material of thicker fabric (such as 0.8mm) can be increased to about 0.8mm/min. At the same time, it can be applied to the external filter dust collector with cantilevered blow back in the middle. For example, EWTF 800 1 RH weft 0.8mm thick expansion yarn filter material is used in FVB L vertical kiln microseismic flat bag dust collector, used in the tail of a large machine kiln, the total filtration air volume is 60000m3/h, the filter area is 2000m2, the maximum filtration speed is 0.58m/min, the gas temperature is generally 50~80 C, the maximum is 200~280 degrees C, the use of one is 200~280. None of the filter bags were damaged in the year. After testing, the dust removal efficiency is over 99.9%, and the dust concentration of the outlet is lower than 50mg/Nm3, and the dust emission concentration is lower than the national target. Daily recovery of 12 tons of raw clinker, according to 300 days / year, the annual recovery of funds of about 600 thousand yuan, resulting in significant economic benefits.
