[Abstract]:According to the demand of industrial production for high temperature flue gas purification technology, the application advantages of ceramic tube filter are pointed out, and the filtration mechanism and characteristics of ceramic tube filter element are analyzed and studied. It provides a reliable theoretical basis for the rational design and optimization of ceramic tube filter structure and control system and for solving practical problems in industrial application. According to the basic theory of aerodynamics, the main mechanism and important factors affecting the filtration performance of ceramic tube filter were studied, and the capture efficiency of each kind of capture mechanism was deduced. Based on the basic laws of fluid mechanics, the fluid flow characteristics in ceramic tube filter are studied, and the effects of main structure parameters and flow parameters on the filtration pressure drop of ceramic tube filter are analyzed. The formula for calculating the pressure drop of ceramic tube filter in the process of filtration is derived. According to the needs of the research and the existing experimental conditions, a set of ceramic tube filter experimental system was set up to study the filtration characteristics of ceramic tube filter under different conditions. According to the gas flow characteristics and similarity theory in ceramic tube filter, the electric simulation model is established, and the model is verified and corrected by the experimental results. The pressure drop characteristics of ceramic pipes with different permeability are predicted by using the electric simulation model, and it is pointed out that the mixed use of ceramic pipes is not conducive to the unified maintenance of the equipment. By using the established electric simulation model, the pressure drop characteristics of ceramic tube filter under different service life conditions are predicted, and the design of ceramic tube filter and pulse backblow system is theoretically guided.
