At present, for thermal power generation, cement production and other enterprises, the control of dust pollution generated in the process of fuel transportation has always been a difficult problem. Belt conveyors are commonly used material conveying equipment in thermal power plants. Materials, such as burning coal, generate a lot of dust during the transfer process, especially high dust materials, such as Xinjiang Guanghui Coal, Xinjiang Guanghui Coal is one of the aforementioned dust materials. It belongs to lignite and has a large dust content. It is coal produced by China Guanghui Energy Co., Ltd. in Xinjiang, China. There are many reasons for dust generation in the transfer station of the conveying system. For example, the raw materials are dry (the surface moisture is low) and it is easy to dust, the transfer point equipment (blanking pipe, material guide trough, air lock, etc.) is not tightly sealed, and the belt conveyor Abnormal operation (deviation, up and down fluctuations, etc.), unreliable dust removal equipment, etc. However, the main reason is that the drop of the drop tube produces induced wind during the transfer process of the material. The upper and lower belts of each transfer station have different levels of drop. When the material passes through, the high-speed falling material compresses the air in the drop tube. , to generate air flow, resulting in dust flying at the outlet of the guide chute and the inlet of the blanking pipe. At present, the dust removal methods widely used in material conveying system transfer stations of thermal power plants, cement plants and other enterprises mainly include dry dust removal and wet dust removal. Dry dust removal is widely used in bag dust removal and electrostatic dust removal. Wet dust removal is mainly based on spray dust removal and chemical dust removal. Among them, chemical dust removal can also be said to be an extension of spray dust removal technology. The dust suppression agent is added to the spray equipment to improve the dust suppression effect. The efficiency is not high, the traditional spray dust removal efficiency is not high, the utilization of water resources is not sufficient to waste water resources, and the residual waste residue transported affects the cleanliness of the working environment.
