Kiln tail dust bag or kiln tail filter bag

Among the many dust collecting materials, the fiber felt P84\pps\fms based on polyimide is a good one. It has enough heat resistance, chemical corrosion resistance and high dust capacity for exhaust gas. Because of the irregular shape of the felt, it has a large specific surface area, so it has good filtration performance. The filtered dust is only aggregated on the surface, but not...
The bag filter has the highest dust removal efficiency and the highest classification efficiency, which is determined by the mechanism of the bag filter. This mechanism is the mechanism of filtration, so that dust can be attached to the filter bag as a dust and filtered with two times of dust. In our country, the strategy of sustainable development is carried out, the environmental protection is strengthened and the total amount of pollutants is controlled. Under the condition of one control double standard, the bag type dust collector will play a great role in the pollution control of dust, soot, sulfur dioxide and dioxin.

 The biggest shortcoming of the bag type dust collector is the need to replace the filter bag. In the past, because of the few varieties of the filter material, poor quality, poor sack technology, and other reasons of the dust removal system, the life of filter bag is short, especially under the condition of high temperature filter bag and strong corrosion of flue gas, some months have to be replaced. The filter bag increases the running cost and maintenance workload and brings inconvenience to users. Now, the filter material in our country has made great progress, the variety is increasing, the quality is increasing, especially the high temperature filter bag is developing rapidly. For example, the P84 high temperature dust filter bag used by the company is the dust filter bag produced by the Austria company, and the PPS high temperature filter bag is selected from the United States and the filter bag made in Japan. 

The United States high temperature dust removal filter bag ten U. S. DuPont Co production of Noah Mexes and Japanese dey company produced Kang  Si collectively. Foreign varieties of filter media can basically be produced in China, and special filter bags developed for specific conditions in China. Sewing bag technology has also been greatly improved. The filter sewing machine of Hang Rui filter material Co., Ltd. is the leading international "three needle and six wire" suture and a series of processes. The filter bags are also exported to developed countries such as the United States, Japan and Australia. With the increase of other technical levels of the dust removal system, the life of the filter bag has been greatly improved to two years, three years, four years, and some even reached seven years, which meets the requirements of the users and reduces the operation cost of the bag filter.
