Application of bag dust filter in power industry

On December 2, 2015, the executive meeting of The State Council decided to fully implement ultra-low emission and energy-saving transformation of coal-fired power plants by 2020. At the same time, the three departments of the Ministry of Environmental Protection, the National Development and Reform Commission, and the National Energy Administration issued the "Comprehensive implementation of ultra-low emission and energy saving transformation of coal-fired power plants" and "Notice on the implementation of ultra-low emission electricity price support policy" and other support policies to accelerate the ultra-low emission transformation of coal-fired power plants. At this point, China has officially launched a comprehensive ultra-low emission work in coal-fired power plants. Ultra-low emission is a systematic project, which faces many challenges, problems and "pain points" in the process of implementation. The State Council decided to clearly stipulate the implementation time of ultra-low emissions, close to or reach the emission standards of natural gas turbine units, and clarify the emission limits, that is, under the condition of 6% of the benchmark oxygen content, the emission concentrations of nitrogen oxides, sulfur dioxide and soot are not higher than 50 mg/cubic meter, 35 mg/cubic meter and 10 mg/cubic meter respectively. 

** Henan Xinxiang Lifelte Filter Co., LTD. ** (hereinafter referred to as "Lifelte"), as a leading domestic environmental protection equipment manufacturer, has been deeply engaged in the field of cloth bag dust removal technology for many years, providing key support for the ultra-low emission transformation of the power industry. Founded in 2003 and headquartered in Xinxiang City, Henan Province, the company is a high-tech enterprise integrating R&D, design, manufacturing, sales and service, focusing on the innovation and application of industrial dust removal, filtration and separation and environmental protection equipment. ** Technical strength and product advantages ** Lifelte has a national enterprise technology center, bringing together nearly 100 experts in the field of environmental protection, and has established long-term cooperation with a number of universities and scientific research institutions to continuously overcome the technical problems of dust removal. The company's independent research and development of "chamber positioning reverse blowing bag dust removal technology" has outstanding performance in the transformation of coal-fired power plants: ** efficient dust removal performance ** : By optimizing the design of the air distribution plate, the internal structure of the original electrostatic precipitator is reorganized into a dust pre-separation device, which effectively intercepts the unburned coal particles, avoids the wear and burn of the filter bag, and the emission concentration can be stably controlled below 10mg/Nm³. ** Intelligent ash cleaning system ** : The use of chamber positioning reverse blowing mechanism and automatic tensioning device to achieve static ash cleaning, reduce the mechanical loss of filter bags, and extend the service life by more than 30% compared with the traditional pulse dust removal technology; ** Localization breakthrough ** : The core technology and key components are all independently designed and produced, the equipment cost is only half of that of similar foreign products, and the operation and maintenance cost is reduced by 20%, significantly improving the cost performance ratio. Lifelte bag dust removal system has been successfully applied to more than 100 power plants in more than 30 provinces across the country, covering thermal power generation, iron and steel metallurgy, cement building materials and other high-pollution industries. For example, after a large coal-fired power plant renovation project adopts its customized solution, the dust removal efficiency reaches 99.99%, the annual emission reduction of soot exceeds 500 tons, and won the title of "National Environmental Protection practical Technology Demonstration Project". 

In addition, the company provides equipment upgrading services for a number of central enterprises such as "Huaneng Group" and "Datang Electric Power" to win market reputation with stable and reliable performance. The company always regards technological innovation as its core competitiveness, has obtained more than 40 national patents and participated in the drafting of a number of industry standards. In recent years, Liffert has focused on the field of intelligent environmental protection and launched the "Internet of Things + dust removal" remote monitoring system to monitor the operating status of equipment in real time, optimize the cleaning strategy through big data analysis, and further reduce energy consumption. At the same time, we actively respond to the "double carbon" goal, develop high temperature and corrosion resistant filter materials, and expand the dust removal applications in emerging markets such as biomass power generation and waste incineration. In the battle of ultra-low emissions in the power industry, Henan Xinxiang Lifelte Filter Co., Ltd. provides an economical and feasible solution for the environmental protection transformation of coal-fired power plants with self-developed technology, efficient product performance and full life cycle services. In the future, the company will continue to deepen technological innovation, help the green transformation of the energy industry, and contribute to the protection of blue sky and white clouds.
