High temperature dust filter bag , generally refers to the filter bag with a temperature resistance above 200 degrees. High-temperature filter bags are divided into two categories: needle felt and glass cloth. Needle felt high-temperature filter bag, is divided into glass fiber needle felt, Fremet needle felt, P84 needle felt, PTFE needle felt, basalt needle felt, etc.; glass fiber cloth is divided into graphite fiberglass cloth, Silicone fiberglass cloth and expanded fiberglass cloth. It is made of pure ultra-fine fiber filter cloth, which is made by fine heat-melting or squeezing, and has high-temperature resistance. Let's take a look at the relevant information about the characteristics and application of high temperature dust filter bags .
High temperature dust filter bag working principle
The high temperature filter bag is a key part of the operation of the bag filter, and usually the cylindrical filter bag is suspended vertically in the dust collector. The fabric and design of the filter bag should strive for efficient filtration, easy removal of dust, and durability.
In the air box type pulse dust collector, when the dust-containing gas passes through the dust collector, the dust is trapped on the outer surface of the filter bag, and the clean gas passes through the filter material into the inside of the filter bag. The cage inside the high-temperature filter bag is used to support the filter bag to prevent the filter bag from collapsing, and it helps to remove and redistribute the dust.
High temperature dust filter bag features
1. The filter cloth is filtered by the thickness of the entire filter layer and belongs to deep filtration;
2. The depth of the entire filter layer from the fiber to form a three-dimensional porous porous structure, from the inside and outside from loose to dense, forming a gradient filter;
3. High dirt capacity, long filtration life, low pressure difference;
High temperature dust filter bag application
High-temperature dust filter bag in accordance with Other high-temperature filter mat production process, production and processing of filter materials, one of the main varieties of high temperature filter material
High temperature dust filter bags have excellent performance in the following applications:
1, the working temperature of 190 °C, short-term operating temperature of 232 °C, melting point of 285 °C, limiting oxygen index of 34 to 35.
2, can be applied to oxygen content of 15% or less.
3. Sulfur contained in fuel or sulfur oxides contained in flue gas has been proved to be resistant to acid and alkali corrosion and strong chemical resistance.
4. Where flue gas contains moisture.
5, in the temperature of 190 °C ~ 232 °C industrial and mining conditions, air to cloth ratio of up to 5:1 to do online cleaning and air to cloth ratio of 6:1 for offline cleaning, high temperature dust filter bag has an excellent performance record.
The above points are the summary of this site for everyone to summarize the characteristics of high temperature dust filter bag product and application of related information, I believe we will have a certain understanding after reading, so that everyone will know a lot, if you have those Want to know can check it out on our website.
