Technical parameter requirements for low-temperature cloth bags in steel plants

September 18,2023

The commonly used low-temperature dust collector bags in steel plants generally require the following technical parameters:

Material: Generally, cloth bags made of low-temperature resistant materials such as polyester needle felt,acrylic needle felt, and P84 are used to ensure they can withstand the corrosion and tensile strength of low-temperature flue gas.

Permeability: The permeability of the cloth bag is an important factor affecting the dust removal efficiency. The general requirements for the bag are high porosity and good permeability to ensure the normal operation of the pulse dust removal system.

Thermal stability: In low-temperature flue gas environments, cloth bags are required to have good thermal stability performance and will not affect their service life due to thermal deformation, shrinkage, and other issues.

Wear resistance: During the steel production process, dust removal bags are prone to erosion by smoke and material impact, so they need to have good wear resistance and extend their service life.

Length and diameter: The length and diameter of the dust collector bag need to be selected based on the specific dust collector model and pulse dust removal system parameters to ensure the best filtering effect and dust removal efficiency.

In summary, the selection of low-temperature dust collector bags in steel plants requires consideration of various factors, including technical parameters such as material, permeability, thermal stability, and wear resistance.

When selecting, it is necessary to comprehensively consider the specific application environment and dust collector system requirements, and choose products with stable performance and reliable quality
