Dust filter bag; Widely used in places such as steel plants, cement plants, power plants, etc. What are the advantages to introduce to everyone?
The range of air volume processing is wide, ranging from only a few cubic meters per minute to tens of thousands of cubic meters per minute. It can be used for dust removal of flue gas in industrial furnaces and kilns, reducing the emission of atmospheric pollutants.
Using dust removal bag filter material, dust cannot penetrate the filter material, it is surface filtration. Whether it is coarse or fine dust, it all settles on the surface of the filter material, that is, it is intercepted by the pore size of the membrane itself. There is no initial filtration period, and it is filtered from the beginning and in the near future. Low voltage, high-throughput continuous operation. Traditional deep filtration media. Dust removal bags are easy to clean and have a long service life.
The surface is not completely filtered. Dust removal bags rely on establishing a dust layer on the surface of the filter material to achieve filtration. The usual industrial filter material is deep filtration. Long filtration time, high resistance, low efficiency, poor interception, high filtration and blowback pressure, frequent dust cleaning, high energy consumption, short service life, and large equipment footprint. Using membrane dust removal bag filter material, dust cannot penetrate the filter material, it is surface filtration. Both coarse and fine dust are deposited on the surface of the filter material, that is, the filtered material is intercepted by the pore size of the membrane itself. There is no initial filtration period, and it is filtered from the beginning and in the near future.
4. Long lifespan. No matter what cleaning mechanism is used, the membrane filter material can play a superior role. It is a filtering material that combines the design function of a dust collector with its filtering function. Therefore, the cost is low. Membrane filter material is a strong and soft fiber structure that is composite with a strong substrate. So it has sufficient mechanical strength, coupled with some ash removal ability, which reduces the cleaning strength. Under low and stable pressure loss, it can be used for a long time, extending the life of the filter bag.
5. Bag filter is an ideal dust removal method widely used, and the dust removal bag (dust filter bag) is known as the heart of the bag filter and plays a very important role in the dust removal effect. The two important aspects that determine the quality of dust removal bags are the quality of the dust removal cloth (dust removal material), such as indicators, filtration accuracy, and air permeability. On the other hand, the production process and quality of the bag are also important factors, as poor workmanship can lead to powder leakage. Dust removal bags mainly include filter press bags, filter bags, and fiberglass high-temperature filter cloth bags; Polyester filter cloth (bag); Flumes needle punched felt filter cloth (bag); Various chemical fiber machine woven filter bags, non-woven fabric filter bags, such as microporous membrane (PTFE) filter bags
When using glass fiber, polytetrafluoroethylene, P84 and other filter materials, they can operate at high temperatures above 200 ℃. Not sensitive to the characteristics of dust, unaffected by dust and resistance, dust removal filter bags have the inherent advantages of high porosity, good breathability, dust collection, and long service life of ordinary felt filter bags. Due to their moderate temperature resistance level, they can reach up to 150 degrees Celsius; Acid resistance, moderate alkalinity, and excellent properties have made it a widely used variety of felt filter materials. The surface treatment method can be burnt, calendered, or coated according to different requirements of industrial and mining conditions. The PTFE dust filter bag can operate continuously at a temperature of 204 ℃ (instantaneous temperature of 230 ℃) and withstand repeated fluctuations in temperature at 230 ℃. It also has outstanding dimensional stability performance.
