In order to achieve ultra-low dust emissions in the multi-section feed area of the bunker, improve the operating environment and achieve environmental protection goals, a series of technical solutions and implementation measures for mobile unloading trucks are formulated through systematic analysis of the dust emission problems in this area. The practical results show that: the sealing belt is used to seal the bunker unloading port, and the sealing design at the connection between the bunker surface and the warehouse top platform is optimized, so that the sealing coverage rate at the opening of the bunker surface reaches 100% ; the application of high drop buffer funnel or chute retractable unloading truck greatly reduces dust; the head bulk cleaning device solves the problem of bulk consolidation and accumulation of the unloading truck's directional wheel; the combination of mobile dust suppression device and dynamic switching control technology of dust removal points improves dust removal efficiency and reduces energy consumption. The results can provide feasible technical support and practical experience for mobile unloading trucks to achieve ultra-low dust emission in the multi-section feed area of the bunker.
