product description:

　　The high-temperature dust filter cartridge filter material is made of stainless steel fiber sintered felt, iron-alumina aluminum fiber sintered felt and stainless steel sintered mesh.

　　The high-temperature dust filter cartridge has the characteristics of high porosity, strong dirt holding capacity, long service life and continuous use at 250-800 °C. It can provide filtration accuracy of 3μ-200μ, filtration efficiency of 99.99%, discharge concentration of ≤10mg/m3, and its outer dimensions can be processed according to user requirements.

　　Application range:

　　It is used in the filtration of medium such as high temperature gas and is widely used in steel mills, power plants, cement plants, natural gas and other industries. It is an ideal substitute for other dust removal materials.

　　High temperature flue gas purification technology

　　The use of high temperature flue gas waste heat recovery and high temperature gas purification is an important measure for energy conservation and environmental protection. In response to the problems of its characteristics and governance, our company has specialized in high-temperature soot treatment in industrial furnaces and kiln, and developed high-efficiency high-temperature dust remover with high-temperature gas filter as the core technology. It does not need to be forced to cool down and directly purify and remove dust. It is a good solution to the problem that other filter materials are easy to "burn bags" due to low temperature resistance and high temperature. The temperature is too low after cooling, other substances are precipitated and the paste bag is bad, the backflushing performance is not good, the filtering ability and efficiency are poor, and the filter material adheres. Problems such as difficulty in unloading, including filtration problems in high temperature conditions and anti-static accumulation explosion-proof conditions. In recent years, a number of furnace and kiln dust control projects have been built in the metallurgical, chemical, building materials and other industries. The main technology has passed the national environmental protection test and is at the domestic leading level.

　　Practical advantages of high temperature dust collector

　　1, high temperature resistance

　　The high temperature precipitator can be used up to 800 °C. Ordinary high-temperature filtration is usually made of Nomex material, and the maximum temperature resistance is only 280 ° C. If the temperature is too high, the filter bag will be thermally deformed, which will cause cracking and burning of the bag. In order to make the temperature lower than 250 °C, it is necessary to increase the huge cooling system, the temperature is lowered, the heat energy is lost, and the polymer oil in the flue gas is precipitated in the liquid phase to form a paste bag, which causes the dust removal device to be unusable. Therefore, the high dust collector is the best choice for purifying high-temperature flue gas, and it will not bend and deform under high temperature conditions, ensuring stable operation of the dust removal system.

　　2, long service life

　　The high-temperature precipitator filter element is made of unique sintered metal material and has excellent wear resistance. Therefore, under normal circumstances, the product life can reach 3 to 5 years, which is 8-10 times the service life of the bag.

　　3, high filtration accuracy

　　Whether it is practical application or independent testing, as long as the design is proper and the supporting equipment is well-made, the high-temperature dust collector can not only meet the purification requirements of ordinary bag filters, but also meet the purification effect that cannot be achieved by the existing bag filter.

　　4, good chemical corrosion resistance

　　Even if the bag is coated, it will be eroded, often damaged by acid-base erosion or hydrolysis; and the bag needs to be fixed with a bag dragon when it is installed, and the keel is made of metal material, which is easily corroded. High-temperature precipitators are self-supporting, do not require bone cages, maintain good chemical stability in most acid and alkali environments, and have high corrosion resistance.

　　5, good regeneration

　　The cleaning cycle of the fabric filter is achieved by the mechanical action of the reverse air flow through the material, directly damaging the surface dust. Due to the friction between the fabric and the metal bracket, continuous stretching and beating can cause premature fabric damage. The filter uses the reverse air flow instead of the mechanical vibration of the filter cloth to achieve the purpose of regeneration. Compared with the bag filter, especially under high temperature conditions, the service life of the high temperature dust collector is significantly prolonged.

　　The high temperature gas filter is the heart of the filter precipitator. It has good high temperature corrosion resistance, excellent backflushing performance, and high opening ratio, which determines the small initial pressure drop, high filtration gas flow rate, and strong structure, which makes it have a long service life.

　　6. Better economic benefits

　　Bag type dust collectors often have high total cost of using bag type dust removal equipment due to short life, expensive equipment, high operation and maintenance costs, and maintenance due to maintenance. The high-temperature dust collector has good filter materials, simple equipment, long service life and no maintenance. The total dust removal cost is far lower than that of bag dust removal equipment.
