In the process of industrial production, dust control has always been an environmental protection issue that has attracted much attention. The key to solving this problem lies in the selection of dust removal filter bags.
However, different types of dust have different properties, including particle size, shape, density, and humidity, which can affect the performance of dust removal filter bags.
Therefore, in the face of different dust characteristics, how to choose the right dust filter bag has become the best problem we need.
Dust filter bags
For dust particles with relatively small diameters, such as PM25. You can choose the dust removal filter bag with higher filtration accuracy, because the higher the filtration accuracy of the dust removal filter bag, the smaller the dust particles it can filter, and the better the filtration effect will be.
For dust particles with relatively large diameters, such as mineral powder, cement, etc., it is recommended to choose dust removal filter bags with good air permeability and wear resistance. Such dust removal filter bags can not only meet the filtration needs, but also have a relatively long service life.
In addition, for manufacturers who need to emit harmful exhaust gases, they can choose polyester dust removal filter bags or polypropylene dust removal filter bags to remove harmful substances in the exhaust gas.
The humidity and viscosity of the dust are also among the factors influencing the selection.
If the humidity of the dust is high, such as the dust generated by hydrometallurgy, mineral processing and other industries, it is necessary to choose a dust removal filter bag with waterproof, oil-proof, anti-corrosion and other characteristics to enhance its durability and dust removal efficiency.
If the viscosity of the dust is relatively strong, such as the dust generated by plastics, rubber and other industries, it is necessary to choose a dust removal filter bag with higher filtration accuracy and anti-stickiness to avoid the dust from adhering to the filter bag during filtration and damaging the service life of the filter bag.
The chemical properties and temperature of the dust are important factors that affect the selection of dust removal filter bags.
If the discharged dust is strongly acidic or alkaline, more attention should be paid to the anti-corrosion performance of the filter bag, such as polytetrafluoroethylene (PTFE) filter bag, when selecting the dust removal filter bag.
For dust with higher temperatures, it is necessary to choose a dust removal filter bag that can withstand high temperatures, such as high-temperature needle felt filter bags or high-temperature synthetic fiber filter bags.
In some special applications, such as high temperature, high pressure, and corrosive environments, it is necessary to choose dust removal filter bags with corresponding properties, such as high-strength polyester fiber filter bags or polyimide (PII) filter bags.
These special filter bag materials generally have higher temperature resistance, corrosion resistance, wear resistance and other properties, which can meet the needs of special applications.
In the face of different dust characteristics, there are several factors to consider when selecting the right dust removal filter bag. Only by selecting the right dust removal filter bag material and model can we ensure the best dust removal effect and production efficiency.
