Although the China baghouse can effectively collect fine particles, it has not taken the fine particles collecting as the focal point of the technical development before. For fine particles, baghouse technology needs to further improve the collection efficiency, reduce resistance and energy consumption. Research and develop host, ultrafine fiber and filter material, test and application technology is needed in order to capture PM2.5 ultrafine dust.
In particular, integrated systems for the removal of toxic and harmful gases and dust for the treatment of waste incineration tail gas should be studied and developed, as well as technologies and equipment for the removal of heavy metals.
The integrated desulfurization and dedusting technology of "ESP + CFB + BF" has been successfully applied in the head flue gas of iron ore sintering machine, so the application of baghouse dedusting technology in the flue gas desulfurization and dedusting system of sintering head should be expanded.
Great progress has been made in reducing the resistance of China baghouse. However, in view of the goal of "energy saving and emission reduction" and the more and more extensive application of China baghouse in the future, it is still necessary to strengthen the research in order to further reduce the resistance and energy consumption of China baghouse.
Although some progress has been made in the development and production of high-temperature filter fiber, the quality is still different from that of other countries so the research and development of these products still need to be strengthened.
Spunlace filter material adopts the technology of high pressure water jet fiber wrapping and felt forming to the structure of horn shaped 3D filter material. The surface has the characteristics of microfiber cloth like membrane, and it is processed into high-efficiency filter material by PTFE bubble coating and other functions.
Water gas industry is developing towards high pressure gas, and the higher the pressure, the higher the gas production rate. It is proposed to build a gas system with working pressure of 0.6m ~ 1.0mpa, and the subsequent goal is to build a gas system with working pressure of 3M ~ 4MPa.
