Optimizing Study of Top Beam Structure of Electrostatic Precipitator Casing

Abstract:

An optimizing design idea is produced for the structure of top beam of electrostatic precipitator casing. The thermos cabinet and the original box shaped top beam of casing compose a truss beam system whose overall section height is increased greatly, resultantly, the bend bearing capacity of truss beam increases significantly than that of the original top beam of casing. Consequently, the wall thickness of box section of the original top beam can be reduced so that the steel consumption can be saved. Based on a practical project, the load effects on truss beam were investigated, respectively, including the air pressure difference and the temperature difference among external layer, thermos cabinet and interior of casing. Besides, the evaluation method of internal force in truss beam was investigated and the selective preference of truss beam configuration was conducted. The unfavorable load cases of air pressure difference and temperature difference are proposed for truss beam design. Besides, the accurate evaluation method of internal force and the design method for economical configuration of truss are proposed. In consideration of load bearing effect of thermos cabinet layer, the optimized design of truss beam originating from box sectioned top beam can ensure the truss works safely and reduce the steel consumption significantly.
