Self Supported Antistatic 1.8mm Dust Collector Filter Bags

Antistatic Sleeve Polyester Filter Bags Anti Static Nonwoven Filter Baghouse Collector Bag


Product Overview

The filter bag is a key part of the operation of the bag filter. Usually the cylindrical filter bag is suspended vertically in the dust collector. The fabric and design of the filter bag should be as efficient as possible for efficient filtration, easy dust removal and durability.


The normal temperature bag is mainly made of polyester, polypropylene, acrylic and other fibers through non-woven and textile technology. It has good air permeability, smooth surface, good dimensional stability, easy to peel off dust and other excellent performance. It is mainly used in dust removal and normal temperature flue gas treatment in industries where dust pollution occurs in general industrial enterprises.


We provide expert support not only filter bag design, but also how to optimize the flow parameters of your system to get the absolute best productivity. This process-specific product design and applications engineering approach has proven to be the best way to optimize your system's performance.

Product details

1.Suture line: Use special lines to seal edges, flat end with triple seam.

2.Material and thickness: Recommand different proportion materials and thickness according to different uses.

3.Material performance: Acid alkali resistance, Abrasion resistance, Corrosion resistance. The filter bags use our material guarantee Filter Precision, so can meet your local government's emission stadard.


Structural Principle

Structural principle: Deep three-dimensional filter material, 100% pure fiber forms a three-dimensional, highly fluffy and tortuous three-dimensional filter layer by needle punching. It is characterized by loose fiber structure, which greatly increases the capacity of impurities.

During use, large particle impurities are trapped on the fiber surface, while fine particles are caught in the deep layer of the material, ensuring No damage due to increased pressure during the use, to guarantee a high filtration efficiency.

Characteristics and Processing Technology

Polyester fiber has high strength, good elastic recovery performance, own the strength of 3.52-5.28CN / dtex, elongation at break can be upto 30% - 40%, fabric has size stability, high strength, good elongation, therefore, polyester fabric provide perfect wear resistance performance.


Polyester fiber has good heat resistance, melting point is 255-265 ℃, burning temperature is 450 ℃, softening starts at 230-240 ℃, and the strength loss caused by heating at 170 ℃ for a short time can recover by itself. Therefore, polyester fiber has good practicality at normal temperature and can work continuously at 135 ℃, so it is the most cost-effective material at low temperature.


The filter bag is just like sewing clothes. If the sewing is not good, the clothes will be intact and the stitches will break and become unthreaded. Therefore, it is necessary to choose a better quality suture, that is, the temperature resistance, corrosion resistance, wear resistance, bending resistance, tensile strength and other characteristics of the suture need to be better than the material of the filter material itself.


The longitudinal seam of the body of the PTFE membrane filter bag is firm and straight, and it has a certain degree of flexibility during the dust removal and dust removal process. When making the bag body of the membrane filter bag, the method of longitudinal double-line sewing is used for sewing. The advantage of this method is that the elasticity and strength are better than the lock stitch. The three-needle sewing can make the strength of the filter bag be greatly enhanced.


Usually the fabric of the filter bag itself is not damaged, and the seam is split, the reason may be that the material of the seam does not meet the requirements, or the quality of the seam sewing is not close, or the seam form may be selected incorrectly.


Application

In general, the application of polyester filter bags cover mine, cement, limestone, iron and steel induestries, electrolytic aluminium, wood processing, non-ferrous metal production, food processing and pharmacy industry.


For Cement Industry, we know that the cement producer all over the world need high-performance filter media for kiln mill, alkali, and other pulse jet or reverse baghouse. Our filter Bags provide emissions control, production increases and the lowest overall maintenance and operating costs.

For Chemical Industry, our filter bag for the chemical industry are offered as thorough solutions.

For Power station and Incineration Industry, with PTFE membrane, our filter bags provide near zero emissions for waste processing and power station boiler. Whether you use standard or low grade coals, wood or tires in your boiler, or operate a chemical, hazardous, or waste incinerator, all we can deliver consistently high airflow over the life of the filter bags for your application.
