Description

Technical Field

[0001] The invention relates to the technical field of dust suppression equipment, in particular to an ultra-long-range intelligent spray dust suppression system. Technical Background

[0002] Railway freight yards often require the construction of large areas of hardened surface sites, especially railway freight yards at ports. As supporting facilities for cargo loading, unloading and transshipment operations, port railway freight yards often have a large amount of bulk cargo loading and unloading operations, which will generate a lot of dust during bulk cargo loading and unloading. In order to improve the air quality of port railway freight yards, it is necessary to carry out spray dust reduction after cargo loading and unloading.

[0003] After investigation and research, it was found that since it is not allowed to randomly erect poles and wire in the middle of the freight yard, the fixed spray dust suppression system can only be installed on the side of the freight yard away from the railway track. However, the port railway freight yard is large in area, and the current fixed spray dust suppression system has a small spray lift and the spray coverage cannot meet the dust suppression needs of the port railway freight yard.

[0004] In order to further improve the air quality of the port railway freight yard, dust suppression vehicles are needed to carry out mobile spray-assisted dust reduction. However, the spray operation speed of the dust suppression vehicle is slow, which is very different from the speed of traffic in the railway freight yard, seriously hindering traffic, posing safety hazards, and reducing the capacity of cargo transportation. In addition, the dust suppression vehicle requires a driver to drive and operate, which has poor flexibility, and is time-consuming to dispatch and work. It not only wastes water resources, but also wastes other energy such as fuel, causing varying degrees of waste of human and material resources, and the effect is poor, and it cannot be controlled anytime and anywhere as needed. Therefore, it is necessary to design an ultra-long-range intelligent spray dust reduction system that can meet the needs of spray dust reduction in port railway freight yards and improve their air quality. Summary of the invention

[0005] The purpose of the present invention is to provide an ultra-long-range intelligent spray dust reduction system to meet the purpose of spray dust reduction in port railway freight yards and improve the environmental air quality thereof.
