PTFE Filter Bags

  

1. Introduction of PTFE filter bags

PTFE is polytetrafluoroethylene, also known as Teflon, is one of the more high-end varieties of bag filter materials. The PTFE synthetic fiber filter bag is a filter bag made of a unique material. It can withstand acid and alkali corrosion in the entire PH value range at a continuous operating temperature of 240℃ and an instantaneous temperature of 260℃. The PTFE synthetic fiber filter bag has excellent self-lubricity, does not absorb moisture, and can withstand ultraviolet radiation. However, the wear resistance of the PTFE fiber filter material is general, so there are stricter requirements (finishness) for the filter bag frame. PTFE fiber filter bags are more suitable for harsh conditions that require corrosion resistance and high requirements for filter material service life.

 

Polytetrafluoroethylene synthetic fiber filter bags can be used for flue gas treatment in coal-fired boilers, garbage incineration, carbon black production, titanium dioxide (TiO2) production and other processes. In the primary smelting, refining and chemical production of some metals, there are also applications for PTFE filter bags.

 

2. The characteristics of PTFE filter bags

 

The surface of the film is smooth and resistant to chemical substances. It is laminated to the surface of ordinary filter materials to act as a disposable dust layer, trapping all the dust on the surface of the film to achieve surface filtration. It has the unparalleled superiority of traditional filter materials.

 

It has the characteristics of high peel strength, large air permeability, low resistance, and uniform pore size distribution.

 

Installed in the dust removal equipment, it will quickly and effectively intercept the ultrafine dust calculated in microns. The dust removal efficiency of the PTFE filter bag is more than 99.99%. It is an effective and economical new filter material for industrial dust filtration and material recovery.

 

The obvious difference from other pure high-performance fiber (PPS, glass fiber, P84, aramid) filter media is: as time goes by, PTFE will not age, accompanied by the joint action of high temperature gas, corrosive gas, and liquid. The breaking strength of the PTFE base fabric will not be attenuated, and the service life will be greatly improved.

 

As a dust collection system manufacturer, Hebei Ou Tai Environmental Protection Equipment Co., Ltd. is located in Botou City, a famous "dust-removing hometown." The factory is located in Xihuan Industrial Park, Botou City, Hebei Province, which is located in the center of Beijing, Tianjin, Jinan, and Shijiazhuang. Beijing-Shanghai Expressway, Beijing-Shanghai Railway, 106 State Road, 104 National Road walk through the city, the traffic is very convenient.

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?

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...
