Strength Analysis And Structure Optimization Of Key Components Of Water-sealed Dust Removal Device

Large amounts of dust is produced in the coke production process to produce, environmental is serious polluted. Using coke dust removal device can reduce the pollution of the environment. Water-sealed dust has good sealing performance, less energy demand, has been widely used in coke dust. The key parts of the dust removing device are dust collector dry pipe and U-turn smoke tube that are designed In the case of meet the job requirements. Because the water-sealed dust dry tube is an important part of the coke dust removal device, device often appear deformation and cracks on the opening part In the the use of the process, the life of dust removing device apparatus is reduced it Reduce the life of the entire apparatus. As dust dry pipe stress situation is more complex, using traditional mechanics of materials to analyze the force is difficult. Elasticity and finite element method can effectively resolve mechanical analysis of the complex structures by discrete complex object. Strength analysis of dust collector dry pipe based on finite element software Pro/Mechanica is given in the paper, Improvement scheme was proposed and validated, The improvement of the structure provides a useful reference for transformation.The optimal designing rely seamless connection of the Pro/E software and Pro Mechanica. the three-dimensional modeling Which is created in Pro/E is analyzed Directly. and the maximum stress area is found.The analysis result as the basis for improved dust collector dry pipe structure. material suffered the maximum stress does not exceed the allowable stress. The optimal parameters is obtained by the global sensitivity Analysis for the fillet radius, opening distance and the thickness of the ribs.The optimum design of the dust collecting dry tube make the structure simplification in the conditions of meet the strength requirements.the structure to achieve the most simplified.Using finite element analysis to optimize the structure can shorten the product design cycle, reduce product cost.
