In the field of industrial dust removal, polyester dust filter bags are widely used basic products. Thanks to numerous practical features, they become the first choice for many conventional working conditions.
1. Material Properties and Advantages
Polyester, scientifically known as polyester fiber, boasts good chemical stability. It has a relatively moderate temperature resistance, with a normal continuous service temperature around 130°C, and can momentarily withstand 150°C. This makes it suitable for conventional temperature environments in most industrial productions, such as dust control in general building materials and mechanical processing industries.
Its wear resistance is outstanding. In working conditions where dust frequently scours and filter bags continuously rub against cages, it guarantees a service life. Moreover, polyester fiber has decent chemical corrosion resistance, tolerating common weak acid – base gases (like acidic and alkaline pollutants in ordinary industrial waste gas) to a certain extent, and is not prone to rapid damage due to chemical erosion.
2. Filtration and Dust – Cleaning Performance
The fiber structure of polyester dust filter bags is reasonable, with evenly distributed pores, enabling efficient dust interception. For fine dust particles, it can achieve good collection through a combination of surface filtration and deep – layer filtration, ensuring exhaust gas meets standards.
During dust cleaning, whether it is mechanical vibration dust cleaning, pulse jet dust cleaning, or reverse air dust cleaning, the polyester material shows good adaptability. It has excellent elastic recovery ability; after dust cleaning, the filter bag can quickly return to its initial filtration state, maintaining stable filtration resistance and ensuring the long – term efficient operation of the dust removal system.
3. Applicable Scenarios and Cases
It is widely used in raw material crushing and conveying links in cement plants, steel mills, as well as dust collection in furniture factories, grain processing plants, etc. Take a cement plant as an example. By using polyester filter bags in the raw material mill system, it effectively collects raw material powder, the system operates stably, and the service life of the filter bags reaches 1 – 2 years. This ensures compliance with production environment and emission regulations, and the cost control is also relatively ideal, demonstrating the reliable value of polyester bags in conventional industrial dust removal.
