Polyester Filter Bag

 1. Introduction of polyester filter bag

 

In recent years, countries around the world have made many efforts in the treatment of environmental pollution and achieved great results. In the treatment of air pollution and material recovery, bag dust removal has achieved good results. The technical core of bag dust removal is the filter material. Bag dust removal is using polyester filter felt to filter the dust in the gas.

 

2. Performance requirements of polyester filter bag

 

People have many requirements for the performance of filter media of polyester filter bag. The main performance requirements are: large air handling capacity, low resistance, long life, and low price.

 

The filter cloth used for dust filtration mainly consists of organic woven filter cloth and needle punched filter cloth.

 

Woven filter cloth is made of twisted warp and weft yarns interlaced on a plane, with a two-dimensional structure. The woven filter material requires a great degree of tightness when weaving the cloth, and the density of the yarn itself and the interweaving part of the filter material is also higher. The actual total opening rate is about 30%, and the resistance of the filter material is greater. The air handling capacity is small, and most of the dust-containing gas can only pass through the pores between the warp and weft threads. Because the pores are large and the direct dust is easily penetrated, it can only be better after the dust layer is formed on the woven fabric. The collection efficiency is low at the beginning of use and a period of time after cleaning. In addition, dust removal is a working procedure that constantly occurs in bag dust removal, which determines the low efficiency of woven filter cloth in bag dust removal.

 

3. Application of polyester filter bag

 

Polyester filter bags are used for air pollution control and material recovery, and are suitable for working at a temperature of 125°C-140°C.

The Electromagnetic Valve 2019

Electromagnetic pulse valves (also known as diaphragm valves) are compressed air "switches" for pulse bag filter dust cleaning systems. By the control of the output signal of the pulse jet control instrument, the filter bag is cleaned by one row (chamber), so that the resistance of the filter is kept within the set range, so as to ensure the processing capacity and dust collection efficiency of the filter. DMF-Z electromagnetic pulse valve  is a right-angle valve, and the angle between the inlet and outlet is 90 degrees, which is suitable for the installation connection between the airbag and the dust blower tube. The air flow is unobstructed and it can provide the required clear air pulse. DMF-ZM electromagnetic pulse valve is the same as the "Z" series of the right-angle valve, suitable for airbag and dust collector spray pipe installation connection, the import and export of the two ends with a fixed nut for installation so that installation and us...

Cartridge Dust Collectors: The Ultimate Guide for Manufacturing Facilities (2026)

 If you’re a factory manager or operations director dealing with industrial dust, you’ve probably heard of cartridge dust collectors —but how do you know if they’re the right fit for your facility? Unlike traditional baghouse dust collectors , cartridge dust collectors are more efficient, easier to maintain, and more compact. This makes them a top choice for modern manufacturing, metal fabrication , woodworking, and chemical processing. Over the past 8 years, I’ve helped many manufacturing facilities upgrade to cartridge dust collectors. This cut maintenance time by 40% and improved air filtration efficiency . In this guide, I’ll explain cartridge dust collectors. You’ll learn how they work and their main benefits. I’ll also cover when to choose them over other systems. I’ll show you how to pick the best one for your operation. You’ll also get SEO tips to help keep your facility compliant and efficient. What Is a Cartridge Dust Collector , and How Does It Work? Inclined cartridge ...

Scraper Conveyor

With a squeegee chain traction, the conveyor that transports the bulk material in the tank is called a scraper conveyor. KS Scraper Conveyor Scraper Conveyor The adjacent middle slot can be flexibly limited in the horizontal and vertical planes. The face conveyor where the fuselage is bent at a 90-degree angle at the intersection of the work surface 1 and the transportation lane is called a "corner scraper conveyor". In the current coal mining face, the role of scraper conveyor is not only to transport coal and materials, but also the operating track of the coal mining machine, so it has become an indispensable main equipment in modern coal mining technology. The scraper conveyor can keep running continuously and production can be performed normally. Otherwise, the entire coal mining face will show a state of discontinued production and disrupt the entire production. The main structure and components of various types of scraper conveyors are basically the same, it consists...
