Description

Tectorial membrane fluorometric needled felt filter bag Technical Field The utility model relates to the technical field of filter bags, in particular to a coated Flumetex needled felt filter bag. Background The filter bag is a bag-shaped container for filtering, is generally made of fiber materials, is mainly used for filtering gas or liquid in the industrial and environmental protection fields to remove solid particles, impurities or harmful substances in the gas or liquid, dust is trapped on the surface of the filter bag when dust-containing gas passes through the filter bag in an industrial dust removing system, clean gas is discharged through the filter bag, so that gas-solid separation is realized, the aim of purifying air is achieved, and in liquid filtering scenes, such as sewage treatment, chemical liquid purification and the like, the filter bag can intercept the solid particles in the liquid to purify the liquid, and the subsequent process requirements or emission standards are met. In the industrial scenes of high dust emission such as steel smelting, cement production, garbage incineration and the like, a tectorial membrane Flumetex needled felt filter bag has become a core component of a dust removal system by virtue of high temperature resistance, corrosion resistance and high-efficiency filtering performance. However, the prior filter bags have two major pain points in practical application, namely, the prior filter bags lack of folding and containing design, occupy large space during storage, are messy in stacking, are easy to cause film coating abrasion on the surfaces of the filter bags and fold a needled felt layer, directly influence the filtering efficiency and the service life, and secondly, the irregular stacking can cause inconvenient taking, increase the time cost of equipment maintenance and filter bag replacement, further influence the continuous and stable operation of a production line and have poor practicability, so the filter bag with the film-coated Flumet needled felt is provided for solving the problems. Disclosure of utility model The utility model mainly solves the technical problems in the prior art and provides a coated fluorometer needled felt filter bag.
