In view of the hazardous materials’ leakage caused by traffic accidents during their transportation, a concept and design of a hazardous materials’ collection truck is proposed for a safe collection and transportation to a professional processing factory. In order to prevent secondary pollution caused by hazardous materials in the vacuum collection process, the gas-solid separation operation must be performed in the hazardous materials collection truck. According to the needs of the gas-solid separation, the structural composition and working principle of the hazardous materials collection truck were analyzed, and the separator was modeled by the finite element analysis method. In the simulation process, the continuous phase flow field simulation of the air is performed first, and on this basis, the discrete phase analysis of the particles is added. The effects of gas flow inlet velocity and particle size on the separation efficiency of the separator were analyzed. Based on the response surface method, the structure of cyclone separator was improved to find the optimal solution and enhance the separation efficiency.
