Bag-type dust removal is an efficient dry dust removal technology, which is simply a filter bag made of fiber filter material and purifies the gas through the dust layer formed on its surface. Bag dust removal technology is an effective way to prevent and control air pollution and reduce industrial smoke and dust emissions.
Xue-jun cao said that the ministry attaches great importance to development of high temperature bag dust removal technology, the technology of bag-type dust collector into the catalogue of advanced technology for energy conservation and emissions reduction, environmental protection filter with textiles, especially high temperature filtration materials as the key point of the development of the industrial support, and support the China textile academy of sciences set up a high temperature filter material of bag-type dust collector development and application of the public service platform, provide the filter bag filter bag production and application oriented enterprise quality performance assessment, the new filter material technology development, the old filter bag recycling industries such as the universal service.
In the past five years, bag-type dust removal has been applied rapidly in urban garbage incineration, coal-fired power generation, cement, steel smelting and other industries, and has become one of the main industrial technologies for flue gas dust removal in coal-fired power plants.
"Gradient filter material, ultra-fine fiber filter material and other key products and technologies have made significant breakthroughs in recent years, prompting the bag-type dust removal technology to achieve fine particulate dust emission concentration of less than 10 mg per cubic meter, or even reach the level of ultra-net emissions. Li lingshen, vice President of China textile industry federation and President of China industrial textile industry association.
Under the concept of green development, the domestic demand for bag-type dust removal is obviously increased, which also drives the rapid growth and development of filter material industry. In the past five years, the filtration and separation textile industry has grown at an average annual rate of 14.7 percent, according to li. In the first half of this year, the main business income and profit of filter textile industry increased by 6.8% and 9.1% respectively, and the export delivery value increased by 15.3%. "With the continuous progress of filter material technology in our country, all kinds of high-performance dust filter bags can fully meet the more stringent environmental standards, and the comprehensive cost has been falling. Li lingshen said.
In recent years, China's bag-type dust removal production technology level has been continuously improved, has reached the international first-class level, domestic production of filter material performance has also been able to compete with foreign brands.
"Bag-type dust removal industry has a good development prospect. How to better play the role of the industry and win a broader development space by improving their own level is the most important task at present. Li xin, deputy director of the China national academy of textile sciences, believes that the bag-type dust removal industry needs to further comprehensively upgrade its technology, enhance product stability and filter material service life in the future. More importantly, it is necessary to accelerate the research and development of applications in different industries. In combination with the complex diversity of production in domestic industrial industries, it is necessary to accelerate the adaptation to the latest demand changes of enterprises. Starting from two aspects of product innovation and after-sales service, it is necessary to produce differentiated products and further improve product quality and service level.
