Bag dust removal industry is a typical policy driven industry. Under the background of the implementation of special emission limits of air pollutants in Beijing, Tianjin, Hebei and surrounding "2+26" cities, special and ultra-low emissions have been normalized, which brings new opportunities for the development of bag dust removal industry. Statistics show that domestic filter materials have accounted for 90% of the market share of domestic filter materials, and the relevant employees reach more than 150000, with total operating income of more than 7 billion yuan and export contract amount of about 420million yuan.
In recent years, the bag filter industry in China has made great innovations and progress in the fields of superfine surface filter material, island fiber filter material, polytetrafluoroethylene membrane filter material, glass fiber and its modified filter material, water prick filter material and composite fiber filter material. It has not only a group of typical medium and large-scale filter material backbone enterprises, but also formed Liaoning Fushun Yingkou filter industry cluster, Funing, Jiangsu Province The filter industry cluster and Tiantai filter industry cluster in Zhejiang Province play a solid supporting role in the development of environmental protection industry in China. Compared with foreign-funded filter material production enterprises, the performance and quality of domestic filter materials have been significantly improved, but it is unavoidable that there are still some problems, which hinder the healthy and sustainable development of the industry, mainly because the market is not standardized, the competition is still serious, and the profits of the industry are still serious Low, insufficient profitability. At the same time, the phenomenon of fake and inferior still exists, the quality of filter material is uneven, and the threshold of industry is too low, which all affect the overall image of bag dust removal industry. Therefore, it is urgent to establish the standards, guide and standardize the development of the industry.
The comprehensive emission standard of air pollutants (GB 16297-1996) is the most stringent air pollutant emission standard in the world. Under the ultra-low emission requirements, domestic filter materials are attracting attention both in product innovation and performance parameters improvement. Technical requirements for filter materials for bag dust removal (t/cae) 21-2019) in the formulation, not only the new requirements of the air environmental protection situation on bag filter material in recent years, but also the actual situation of the filter material processing technology and equipment progress, the development and application of new filter products are considered. The naming and classification, performance index parameters and test methods are specified, which reflect the advanced index and performance of the filter material, the application of bag dust removal and air pollution control System has positive significance.
The technical requirements for bag filter materials (T / CAE 21-2019) are not only compatible with and covering the contents of the filtration performance test methods mentioned in the national standards of the United States, Germany and Japan, but also ISO The standards of filtration performance and durability test methods mentioned in international standards also include some important indexes of filter materials not mentioned in the above national and international standards. More importantly, the standard is not only a method standard but also a product standard, which is not available in foreign standards. The implementation of this standard will not only standardize the filter material market, promote the technological progress of small enterprises, strengthen the quality of filter products, improve the application level of filter materials, but also facilitate the rapid entry of filter products and enterprises in China into the international market and realize large-scale export and foreign exchange.
Technical requirements for filter materials for bag dust removal (t/cae) 21-2019) including filter material definition, terms, technical requirements, testing methods, inspection rules, product marks, packaging, transportation and storage and transportation, etc., which can provide the basis for the standardized production and inspection of filter materials, guarantee and improvement of product quality, create necessary conditions, provide basis for the supervision department to implement product inspection, and facilitate users to select filter materials conveniently and correctly, and improve smoke and smoke The effect of dust control can promote the development of dust control technology in China and promote the sales of domestic filter materials at home and abroad. The formulation and implementation of the standard will certainly achieve obvious social, environmental and economic benefits.
