Description

Technical Field

[0001] The utility model relates to the technical field of dust prevention and suppression, in particular to a chemical dust suppression system for coal loading and unloading. Background Technique

[0002] As an important energy source and industrial raw material, a large amount of dust will inevitably be generated during the loading and unloading process of coal. These dusts not only seriously pollute the environment, but also pose a threat to the health of operators, increasing the risk of occupational diseases. At the same time, the dispersion of dust will also affect the quality of life of surrounding residents and may cause damage to nearby equipment. It is necessary to carry out dust suppression treatment on the dust and wind and dust dispersed by coal. Therefore, dust suppression equipment is required to carry out dust suppression and dust prevention operations on the wind and dust dispersed by coal.

[0003] At present, during the unloading process of domestic specialized coal unloading terminals, the escaped dust is usually treated by a dust suppression system, and dry fog dust suppression or direct sprinkling is used for dust suppression and dust prevention treatment. In the case of relatively dry coal, the dust suppression effect is not ideal, and physical coverage is difficult to completely prevent the dispersion of dust, especially it is easy to be damaged during the loading and unloading process; while the water spray dust reduction can temporarily reduce the dust concentration, but the water consumption is large, and it is easy to form runoff on the ground, increasing the difficulty and cost of subsequent cleaning, and the chemical dust suppression ability of the device is relatively insufficient. The dust is relatively serious during coal loading and unloading, and the installation and operation of the overall device are inconvenient, and the applicability and adaptation range are not wide enough. Therefore, we propose a chemical dust suppression system for coal loading and unloading to solve the above problems. Content of the Utility Model
