The cost factors affecting the pulse bag filter: The main factors affecting the cost of the pulse bag filter body are the gas to cloth ratio and filter material. If the selected air cloth ratio is too small, the volume of the dust collector, the number of filter bags used, the dust removal unit, the matching baffle valve, and the equipment of the dust cleaning device will increase accordingly, resulting in a significant increase in the cost of the main body. The prices of different filter materials vary greatly, and once the air to cloth ratio is determined, the price of the filter material is key to reducing the main cost. The development of pulse bag dust collectors: Pulse bag dust collectors are generally used in environments with severe dust pollution such as steel, smelting, chemical, power generation, and cement. Due to the harsh working environment of pulse bag dust collectors, inadequate maintenance and management can shorten their service life. Therefore, maintenance and repair of pulse bag dust collectors are important for their normal operation, full play of their role, extension of their service life, and effective dust removal work. In order to maintain and repair the pulse bag filter, it is necessary to be able to use and inspect it, identify problems, and handle them in a timely manner to ensure the normal operation of the dust removal system. During the operation of the pulse bag filter, it is necessary to regularly check the working condition of the main unit and dust removal accessories, and do a good job in maintenance and upkeep. Another important manifestation of the long service life of pulse dust collectors is the long trouble free operation time of the filter plate, which does not require daily maintenance and upkeep similar to bag filters. And good cleaning characteristics will maintain its stable equipment resistance, allowing the sintered plate filtration device to achieve long-term maintenance free operation. Its pressure resistance, air shock resistance, and air impact resistance are much stronger than cloth bags, so its service life can generally reach more than 10 years; Wide adaptability - Suitable for all types of dust, it has the advantage of being a sodium level dust, and the original concentration of processed raw dust can be within 500mg/m3cc, eliminating the need for pre dust removal equipment in the system; Good moisture and trace oil resistance, capable of handling condensed smoke and dust, as well as hygroscopic water dust coexisting dust, including chemical dust and water mist; Not affected by dust particle size and specific resistance, the dust removal efficiency remains stable and unchanged; The dust cleaning control system adopts an intelligent control system and a compressed air blowback device to ensure the spraying effect. Each component is designed and manufactured with a lifespan of. The application prospects of pulse bag filter technology in the cement industry: In 2012, China's cement production reached 2.184 billion tons, with 125 new production lines and an additional clinker production capacity of 160 million tons. According to the "12th Five Year Plan" for the development of the cement industry, during the 12th Five Year Plan period, with the accelerated transformation of the economic development mode, the demand for cement in the domestic market will gradually shift from high-speed growth to stable growth, with a significant slowdown in growth rate. However, the development of cement substrates and products will accelerate. The plan clearly proposes to promote emission reduction technologies and equipment, advance nitrogen oxide treatment, and reduce the total amount of atmospheric pollutant emissions. The increase in concentration of cement enterprises is conducive to the promotion and application of pulse bag dust collector technology, and also provides development space for pulse bag dust collectors in the cement industry in the future. Of course, only some companies in the pulse bag filter industry will share the market of the cement industry. For existing cement enterprises, there is a small number of enterprises and projects that initially had high requirements for environmental protection technology and equipment in engineering design and selection. They chose bags and electrostatic precipitators that can meet the requirements of the new standards. However, most of the existing cement production enterprises, especially some early built cement plants, often have problems such as insufficient environmental protection investment and incomplete environmental protection facilities due to investment control and other reasons at that time. In addition, the early emission standard requirements were relatively low, and the selected dust removal facilities were also selected and configured according to the old standards. Therefore, it is difficult to meet the emission limit requirements of the new standards. The application prospects of pulse bag filter technology in the steel industry: In the "Several Opinions on Guiding the Healthy Development of Industries through Overcapacity and Repetitive Construction in Some Industries" approved by the State Council and forwarded to ten departments including the National Development and Reform Commission and the Ministry of Industry and Information Technology, it is specially proposed to support large-scale steel enterprises with conditions to develop key varieties such as million kilowatt thick plates and high-voltage boiler tubes for thermal power and nuclear power, high magnetic induction low iron loss oriented silicon steel for transformers above 250000 kVA, and tool steel. Accelerate the elimination of hot-rolled ribbed steel bars with strength below 335 megapascals, promote steel bars with strength of 400 megapascals and above, and upgrade and replace building steel. This will be beneficial to the development of large-scale steel enterprises. Affected by this, pulse bag filter enterprises with high technological content and equipment level will participate in the opportunities brought by the structural adjustment of the steel industry and share the demand for new markets in the steel industry. Under the promotion of energy-saving and emission reduction policies and environmental protection industry policies, the market for blast furnace gas dry pulse bag dust collector equipment will continue to maintain stable growth, and further promote and adopt blast furnace gas dry pulse bag dust collector systems. Some areas in the steel industry that are difficult to remove dust may make breakthroughs during the 12th Five Year Plan period, such as pulse bag dust collectors for converters. Sintering flue gas is very different from thermal power generation flue gas. Sintering flue gas has a large and unstable volume, with large changes in flue gas temperature, SO2 concentration, moisture content, complex composition, high oxygen content, and difficult comprehensive treatment. Mature sintering flue gas desulfurization processes such as activated carbon adsorption and limestone gypsum method are difficult to promote and apply in domestic steel enterprises due to their high investment and operating costs. In recent years, domestic desulfurization enterprises have independently built and operated various sintering flue gas desulfurization devices based on China's national conditions and mature technologies. However, overall, these processes generally have problems such as low technological maturity, unstable operation, low comprehensive utilization value of by-products and difficult disposal, large amount of wastewater, and high comprehensive operating costs, which have affected the confidence of Chinese steel enterprises in building sintering flue gas desulfurization facilities. Some steel companies are indecisive and adopt a wait-and-see attitude in technology selection, while others choose different processes to build desulfurization units on several sintering machines, causing great inconvenience to operation and management.
