Different types of dust bags have different stains inside, so that the methods and steps required for cleaning are different, but of course this we still need to simplify or increase the number of cleaning steps according to the actual situation. Common dust bag cleaning steps such as experiments for processing, bag cleaning, bag drying, bag repair, bag testing, etc. 1. Dust bag using high-frequency vibration, vibration can be as soon as possible through the filter bag above the various impurities to clean up a part. The larger dust particles entering the surface of the filter bag will be removed as far as possible, and will not have an impact on the fastness of the fiber entanglement, to maintain good peel resistance of the filter bag. 2. Dust bag chemical experimental treatment, which can not only deal with the bag impurities, at the same time will not damage the bag material. Extract bag samples, the use of professional instruments, laboratory testing of filter bag oil composition, so as to choose the appropriate washing materials, the maximum wash filter bag without causing any damage to the filter bag. 3. Dust bag cleaning can better help remove the stains of the bag Choose suitable washing materials and strict ratio, low temperature water cleaning, even water flow, moderate strength, no mechanical damage to the filter bag. 4. Drying of dust bag can guarantee better flatness of the bag without deformation Use 110℃ hot air drying, keep the size stability of dust filter bag, no deformation and no shrinkage after drying. 5. Dust bag repair can better protect the integrity of the bag Repair of damaged filter bags such as abrasion and holes due to use ensures a high reuse rate. 6. Dust bag testing can guarantee whether the bags are cleaned to standard The physical indicators of the cleaned filter bags are tested by instruments to ensure that the cleaning quality meets the requirements.

With the support of 16 academicians, more than 30 nominating organizations and more than 100 nominating and judging experts, the 2021 Environmental Technology Progress Award was successfully completed, with 31 projects winning the first and second prizes. According to incomplete statistics, the award-winning achievements in 2021 include 15 international patents, 471 invention patents and 550 other intellectual property rights such as utility model patents; from 2018 to 2020, the related output value will be as high as 50 billion yuan and the profit will be 10 billion yuan, which fully reflects the acceleration of China's environmental technology innovation. Among them, Yuanchen Technology won the second prize of 2021 Technology Progress Award for the key technology research application of special denitrification catalyst for cement kiln flue gas treatment. Part of the project team Project Introduction: The further improvement of pollutant emission standards in cement industry is an inevitable trend for the development of the industry. Currently, most of the production lines in domestic cement industry adopt "low nitrogen combustion + SNCR" technology to treat NOx, but with the tightening of national environmental protection policy, the current treatment technology in cement industry can hardly meet the ultra-low emission requirements, and SCR denitrification technology is the ideal choice at this stage. The high dust concentration, large alkaline content, small particle size and high viscosity in cement kiln flue gas can have a serious impact on common vanadium and titanium denitrification catalysts. Combined with the characteristics of cement kiln flue gas, the application of SCR denitrification technology in cement kilns requires the corresponding denitrification catalysts to be resistant to dust scouring, alkali/alkaline earth metal poisoning, ultra-fine dust coverage and heavy metal poisoning. In order to make the denitrification catalysts with these properties, a large number of other additives are added during the catalyst preparation process. These denitrification catalysts containing large amounts of additives will become hazardous waste at the end of their 2-3 year service life. According to statistics, about 100,000 m3 of waste denitrification catalysts will be produced in China every year, and their unreasonable disposal will seriously threaten the ecological environment. Although the resource recycling technology of vanadium-titanium-tungsten catalysts represented by power plants is relatively mature, the modified denitrification catalysts for cement kiln flue gas still face technical difficulties in resource recycling of spent catalysts. Therefore, the research and development of high-efficiency denitrification catalysts for cement kiln flue gas treatment and its resource recycling technology is the key to realize the technological upgrading and sustainable development of cement industry. After 2 years of research and development, th...

On May 19, a video symposium on the theme of "Responding to the challenges of the epidemic and promoting the sustainable development of environmental protection industry" was held in the conference room of Tongxing Environmental Protection at Binhu Financial Port in Hefei. The meeting focused on the development of the environmental protection industry at the time of the epidemic to find solutions to the difficulties and pain points, to promote the province's high-quality development of environmental protection industry to contribute to the wisdom and role of the three sides of the government, enterprises and associations. Mr. Xu Hui, Chairman of Yuanchen Technology was invited to attend the seminar and make a speech, the following is the content of the speech, If there is one word to describe the characteristics of the current environmental protection industry, I think it must be the word "revolution". Compared to the "stability" of the industry's underlying technology, there is a big change brewing outside the environmental industry, and it's not too much to call it the big revolution of the century. These disruptive changes are large enough to reshape the new landscape of the environmental industry in the next 3-5 years. We all know that globalization is entering a new period: on the one hand, with the development of the international division of labor, scientific and technological progress and the flow of transnational capital, the process of globalization continues to advance; on the other hand, the rise of global protectionism, frequent trade strife, coupled with the repeated attacks of the epidemic, Russia-Ukraine war beyond expectations (the U.S. and Western sanctions against Russia is very intuitive for China to think about), so that the world is in turmoil, set off a wave of counter-globalization, but also make the past high division of labor, deep integration of globalization repeated, regional economic ties increased, the global supply chain showed fragmentation, the industrial chain and supply chain encountered new challenges. Since the beginning of 2020, the world has started to see a keyword appear frequently: carbon neutrality, and its heat has been stacked up several times. So, why does carbon neutrality appear so frequently? In fact, it can be summarized more accurately in one sentence: the current carbon peak and carbon neutrality have become the biggest political issue in China, as well as the biggest political issue in the two trade camps of developed and developing countries in the world. On the one hand, as the world's largest emitter of carbon emissions, China's industry has not yet fully emerged from the dilemma of the "high input, high consumption and high emission" development model, and ecological environmental protection is still facing multiple pressures such as tightening resource and energy constraints and continuous improvement of environmental quality requirements. On the other hand, carbon neutrality is...

On May 19, a video symposium on the theme of "Responding to the challenges of the epidemic and promoting the sustainable development of environmental protection industry" was held in the conference room of Tongxing Environmental Protection at Binhu Financial Port in Hefei. The conference was attended by more than 40 representatives from more than 10 key enterprises, including Guo Chengzhan, Secretary of the Party Committee and Chairman of China Environmental Protection Industry Association, Luo Hong, Deputy Director and First Inspector of the Provincial Department of Ecology and Environment, and relevant officials from the Science and Finance Department. Mr. Xu Hui, Chairman of Yuanchen Technology, was invited to attend the seminar and make a speech. The meeting hit the epidemic when the development of the environmental protection industry there are difficult pain points to explore solutions to promote the province's environmental protection industry to contribute to the high-quality development of the political, business and tripartite wisdom and responsibility. Xu Hui, chairman of Yuanchen Technology, believes that the uncertainty of the international situation, sudden impact, coupled with the repeated impact of the epidemic, although making business operations are facing a shortage of funds, rising raw material prices, slowing demand, the lack of key technologies and the lack of core manufacturing and other circumstances. But the risks and opportunities coexist, "danger" and "opportunity" complement each other. From the external environment, with the advent of the Internet era, the global new round of scientific and technological revolution and industrial change, the environmental protection industry "used to look at capital, now look at management, the future look at technology" trend is also becoming more and more obvious. From the internal environment, under the influence of uncertainties, the environmental protection industry is in urgent need of technological innovation, including basic technological innovation, innovation in high value-added technologies and model innovation, which functional high-end materials R & D breakthroughs to meet the needs of national development, the consumption of pollutant stocks, to solve a variety of environmental problems of the moment. In particular, to implement the "double carbon" strategy, China needs to strongly promote the transformation and upgrading of "high energy-consuming and high-emission" enterprises, build a new development pattern of green economy, encourage the recycling of resources, and build more zero-carbon industrial parks, zero-carbon hospitals, schools, factories and communities. factories, communities and other new industries. For environmental protection enterprises, they must take the initiative, actively respond to the trend of the times, actively seize the major development opportunities brought about by the "dual carbon" strategy, actively embrace the new changes brought ab...
