In the past ten years, China's aluminum industry has made great progress. The aluminum smelting process uses aluminum oxide as the raw material, fluoride salt as the flux, carbon material as the conductor, and the production process of aluminum metal by electrolytic method. The main equipment is electrolytic cell. Production process It will produce a lot of harmful substances such as fluoride and dust, which is a serious pollution production process. For example, in an aluminum plant in the city, the air volume of the electrolytic cell system is 2.7 million cubic meters per hour and 291,000 million cubic meters per hour, and the imported dust concentration is 30g / m3 to 50g / m3, using 16.68 million square meters and 2. Pulse bag type dust collector, with an area of 170,000 square meters, the outlet concentration drops to 9. 11 mg / m3 and 9 mg / m3. 34 mg / m3, the dust concentration at the outlet is 0.22 mg / m3 and 0 .84 mg / m3. The development of the bag filter industry is rapidly adopting a bag filter to purify the flue gas system of the aluminum electrolytic cell. The technology is mature and reliable, which effectively controls the flue gas pollution of the electrolytic cell and completely solves the problem of flue gas pollution in the electrolytic cell.
At present, with the rapid development of the bag filter industry, the maturation and improvement of the production technology of filter materials such as pulse bag filters, especially the revolutionary progress of filter materials and ash cleaning methods, the technical performance of bag filters A qualitative leap ... On the basis of digesting and absorbing foreign advanced technology, bag dust collectors have been successfully applied to high-temperature flue gas dust removal in power plants in recent years. So far, the dust removal device is operating in good condition.
In addition, environmental protection policies have greatly increased the requirements for soot emission. A new “Emission Standard for Pollutants from Thermal Power Plants” (gr 13223-2003) has been released. The new standard has raised the soot emission concentration of coal-fired power plants to 50m g / m3. Some local environmental protection departments have put forward more stringent requirements. The allowable concentration of smoke and sulfur dioxide in a certain city is higher than many advanced standards. From November 1, 2005, the boilers of thermal power plants that have been put into operation can only emit 30 mg / m3 of smoke and dust. Even if the recently operated esp is changed to five or six electric fields, it is difficult to meet the emission requirements.
制造商. 袋式除尘器除尘技术和袋式除尘设备在工作原理研究、结构形式、除尘技术水平等方面取得了良好的效果. 但是，与国外发达国家相比，我国在这方面还比较落后，还有很长的路要走. In recent years, the bag dust collector industry has developed rapidly. With the continuous improvement of China's requirements for bag dust collector technology, the bag dust collector industry has developed rapidly, and a large number of bag dust collector manufacturers have appeared. Bag dust collector dust removal technology and bags Type dust removal equipment has achieved good results in terms of working principle research, structural form, and level of dust removal technology. However, compared with developed countries abroad, China is still lagging behind in this regard and has a long way to go.
At present, due to various restrictions, China's large-scale bag filter is still in its initial stage in the design process. The bag filter industry has developed rapidly, and its technological level and innovation ability are not high. Compared with foreign developed countries, China's technological level is significantly biased Low. Judging from the current operation of bag dust removal equipment in China, short service life of filter bags and uneven air distribution are common problems. This will seriously affect the dust removal effect and have a greater impact on the environment and air quality. During the dust removal process In order to improve the comprehensive performance of the bag type dust removal equipment, it is necessary to consider the various factors in the equipment to ensure its dust removal efficiency and quality.
