1. High temperature flue gas purification technology High-temperature flue gas waste heat utilization and high-temperature gas purification and recovery are important measures for energy conservation and environmental protection. In view of its characteristics and problems of governance, our company has professionals engaged in the treatment of high-temperature soot in industrial furnaces and kilns. It has developed high-efficiency high-temperature dust collectors with high-temperature gas filters as the core technology. It does not require forced cooling and directly purifies the dust. It is a good solution to other filter materials because of low temperature resistance and high temperature, it is easy to "burn the bag", after cooling, the temperature is too low, other substances precipitate and paste the bag, the reverse blowing regeneration performance is not good, the filtering capacity and efficiency are poor, and the filter material adheres Difficult to unload and other problems, including filtration problems under high temperature conditions and anti-static accumulation and explosion-proof conditions. In recent years, it has undertaken a number of furnace and kiln dust control projects in metallurgy, chemical industry, building materials and other industries. Second, the practical advantages of high temperature dust collector High temperature resistance The highest applicable temperature of high temperature dust collector can reach 800 ℃. Ordinary high-temperature filtration is usually made of Nomex material. The maximum temperature resistance is only 280 ℃. Excessive temperature will cause the filter bag to deform thermally, which will cause rupture and burning. If the temperature is lower than 250 ° C, a huge cooling system must be added. When the temperature is lowered, both heat energy is lost and the polymer oil liquid phase in the flue gas is separated out and pastes, which makes the dust removal equipment 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 to ensure the stable operation of the dust removal system. long lasting The filter element of the high-temperature dust collector is made of a unique sintered metal material and has excellent wear resistance. Therefore, under normal circumstances, the product life can reach 3 to 5 years, which is 4 to 6 times the service life of the cloth bag. High filtration accuracy Whether it is practical application or independent testing, as long as it is properly designed and the supporting equipment is well-made, the high-temperature dust collector can not only meet the purification requirements that can be achieved by ordinary bag filters, but also meet the requirements that cannot be achieved by existing bag filters Purification effect. Good chemical corrosion resistance Even if the bag is coated, it will be eroded, which is often damaged by acid or alkali corrosion or hydrolysis; and when the bag is installed, it needs to be fixed by the bag dragon, and the keel is made of metal material, which is easily corroded. The high-temperature dust collectors are self-supporting, do not need bone cages, can maintain good chemical stability in most acid and alkali environments, and have high corrosion resistance. Good reproducibility The cleaning cycle of the fabric filter is realized by the mechanical action of the reverse air flow through the material, which directly shakes off the surface dust. Due to 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 extended. High temperature gas filter is the core of filter dust collector. It has good high-temperature corrosion resistance, excellent backflushing performance, high opening rate determines the small initial pressure drop, high filtered gas flow rate, solid structure makes it have a long service life and other characteristics. Better economic efficiency Bag dust collectors are often short of life, expensive and expensive supporting equipment, high operation and maintenance costs, maintenance shutdowns and other reasons, resulting in high total cost of using bag dust collectors. The advantages of high temperature dust collector filter material, simple equipment, long life, no maintenance, etc., make the total cost of dust removal far lower than bag type dust removal equipment.
