The temperature range that the dust filter bag can withstand

Dust removal filter bag is an important dust removal equipment and is widely used in various industries. The service life and effect of dust removal filter bags are directly related to the operational stability and efficiency of the equipment.
Dust removal filter bags need to be used in a variety of different working environments. Therefore, the filter bags need to have strong high temperature resistance and corrosion resistance.

Before using the dust removal filter bag, we need to understand the temperature range that the dust removal filter bag can withstand, so as to better use the filter bag and ensure its working effect and lifespan.
HEADING FILTER dust removal accessories manufacturers will introduce in detail the temperature range that dust removal filter bags can withstand.

Common materials for dust filter bags include wire mesh, non-woven fabrics, needle felt, etc. These materials have different temperature resistance ranges, so the temperature resistance ranges of dust filter bags are also different.

Common wire mesh materials can usually withstand temperatures below 250°C, non-woven materials can withstand temperatures below 120°C, and needle felt materials can withstand temperatures below 300°C.

In addition to the temperature resistance of the material itself, the structure and process of the dust filter bag will also affect its temperature resistance range.

The structure of dust removal filter bags is usually divided into cylinder type, sleeve type and type structure. The temperature resistance range of cartridge filter bags is usually below 250°C, while the temperature resistance range of sleeve filter bags and type filter bags is relatively higher and can withstand high temperatures below 300°C.
If the filter bag needs to be used at higher temperatures, it can adopt a double-layer or multi-layer structure, or use high-temperature materials such as metal fibers.

The process of the dust filter bag will also affect its temperature resistance range.
During the production process of filter bags, different processing technologies, such as heat treatment, coating, etc., can be used to improve the temperature resistance of the filter bags. At the same time, the seams of the filter bag also require special treatment to ensure that they will not melt or deform under high temperatures.

Generally speaking, the temperature resistance range of dust filter bags is around 250°C to 300°C, but there are also some high-temperature products that can withstand higher temperatures. When using dust removal filter bags, it is necessary to select appropriate materials and structures according to the specific working environment, and pay attention to the service life and maintenance of the filter bags to ensure the normal operation and long-term stability of the equipment.
