The selection of filter material needs to be optimized
For environmental protection technology, to achieve "near zero emissions", it is not a technological upgrade and product performance improvement. This is a systematic problem - including the synchronous coordination of a series of life cycle, such as host design parameters, filter material selection, filter bag quality, installation and operation, etc., and even requires the support and coordination of other environmental protection equipment, such as desulfurization and denitration equipment. Here, the selection of filter material plays a crucial role. Whether it is pure bag dust collector or electric bag composite dust collector, filter material is the core of vitality - "good filter material can have good performance and ensure the bag has longer life." The performance and life are the key indexes for power enterprises to decide whether to choose bag type dust remover.
It is gratifying that in recent years, with the development of filter material, the life of filter bag has been greatly improved. At present, the focus of the industry on filter bag has shifted from extending its life to improving its performance. For the industry, this is undoubtedly a leap over transformation, which marks the research of bag dust remover is directly hitting the core of technology upgrading.
The fine and ultra fine filter material technology is being developed to solve this problem. The technology can achieve the balance of resistance and efficiency, non-destructive manufacturing, greatly improve mechanical properties, solve the inherent defects of filter materials, and finally upgrade the filtration mechanism through three-dimensional asymmetric structure, high pressure water technology, surface FCT nano coating treatment and high temperature hot pressing film coating technology. In addition, experts from energy conservation and environmental protection branch of China Electric Power Union also revealed a good news: new breakthroughs have been made in the detection of filter materials in the near future. A public service platform project for filter material detection in coal-fired power plant conducted by Ministry of industry and information technology has been approved. The next step will not only carry out the filter life test, comprehensively evaluate the filter material, but also carry out the research on filter material recovery . At that time, the recovery and utilization of cloth bags is also expected to be better solved.
