Analysis of the structural parameters of the dust hood in a soda particle gas-solid jet removal plant

Abstract

In view of the demand for airport marking renovation and removal and the current development of soda particle gas-solid jet removal technology, the structure of the suction hood of the soda particle marking removal equipment is optimized and designed. Firstly, FLUENT software is used to simulate the simultaneous suction of soda particle jets and to analyze the effect of negative pressure suction on the gas-solid jet under different hood structures and different pressures. The main structural parameters are the size of the dust hood baffle diameter, the height of the baffle and the width of the dust suction opening. Using the orthogonal test method, the internal flow field of the dust hood is simulated by FLUENT for each orthogonal combination of structure and pressure parameters, and the attenuation effect of dust suction on the jet is analyzed and compared to obtain the optimal parameters for the hood structure with the lowest attenuation rate.
