Optimization Of The Structure Of Electrostatic Precipitator

Along with the increasingly serious problem on environmental pollution in China,the government take ENVIRONMENTAL PROTECTION LAW as a powerful weapon to increase the environmental pollution supervision,inspection and punishment.The air pollution is one of the main components of China's current environmental pollution.The main performance is: coal-fired emissions of flue dust and SO2 are the main pollutants of air pollution;dust is the most extensive involving and the most serious hazard pollutant in atmospheric environment.At present,Chinese air pollution is mainly caused by the coal firing.The main pollutants are dust and SO2.Terminal treatment is still the basic means to control environmental pollution in our country at a long time.Electrostatic precipitator(hereinafter called ESP)is one of the main means to handle the dust in coal fired emissions.With the single ESP treated flue gas volume increasing and emission concentration smaller and smaller,ESP is becoming bigger and bigger,the length,width,height of single set often reach to 35 x 30 x 25 meters,hence it is a large span space structure equipment,the single steel consumption is also growing,the weight often reaches to more than 1 thousand tons per set,the unit cost is also higher and higher,so it is necessary to optimum design the ESP structure and reduce single set steel consumption,decrease the manufacturing cost of the equipment,and improve the market competitiveness of the products.Aiming at the existing problem of ESP,Through research,analysis and contrast all kinds of optimization analysis method,This article uses the STAAD structural calculation analysis software to finite element analyze and design the structure parts of ESP,and according to the results of the software analysis,optimization design of main load bearing parts of the ESP,such as air inlet hood,air outlet hood,hopper,the side girders,the inlet front girder,the outlet front girder and the box girders,so as to increase the stability of the structure and makes full use of the materials,reduce the weight of the equipment,reduce the cost and improve the product cost performance and improve the product market competitiveness.
