dust suppression

Railway dust suppression vehicles, also known as spray bar dust suppression vehicles, folding arm dust reduction vehicles, railway dust suppression spraying vehicles, etc., belong to a type of dust suppression and solidification agent spraying device for coal loading and unloading points, mainly serving the railway, road and other fields. When coal is transported by train, the wind is strong, and coal dust falls on both sides of the railway with the wind. Moreover, the dust accumulates in the railway tunnel, endangering the safety of driving. The spray bar dust suppression car can solidify the coal on each train, form a protective film, reduce pollution, and effectively suppress accidents caused by coal dust combustion in railway tunnels. This type of vehicle also has the function of a sprinkler truck, which electrically lifts and rotates the sprinkler and lifting rods during spraying operations; Replacing the hydraulic system, it is easy to operate, cost-effective, and forms a hard shell on the coal surface by spraying solidifier and dust suppressant, covering the coal underneath the hard shell. During transportation, it is not easily blown away by the wind or lifted by coal dust.

This railway dust suppression vehicle comes standard with front flushing, rear spraying, and a rear platform anti-aircraft gun. The spray system is equipped with a single flow meter (used to measure the amount of dust suppression agent sprayed) and can be displayed on the human-machine interface in the cab. It can view the spray flow rate of each train and cargo compartment in real time and print data tables. The sprinkler system is equipped with a hook stop spray system (contact induction spray, two section train leather inspection stop spray) and has hook stop spray functions on both sides. During spraying operations, it can achieve uniform spraying on the coal seam surface, suitable for different vehicle models, without overflow phenomenon. The spraying arm has vehicle number recognition and recording function. The whole vehicle spray system, single vehicle flow meter, and vehicle number recognition recording function are all connected and reflected on the intelligent computer screen. When the spray principle is in standby mode. The spray arm is located above the maintenance and recovery platform parallel to the railway tracks. When in operation, after the traction locomotive passes, the spray arm rotates to a position perpendicular to the carriage, and adjusts its height (3.5-5.5 meters) to lower it to 30CM above the train carriage. The vehicle identification system detects the vehicle model and number, and under the control of the PLC, the spray drum starts spraying according to the principle of stopping spraying with hook gear. After spraying is completed, the system switches to the cleaning state, cleans the pipeline and nozzle, and the cleaning solution flows back to the mixing tank. When the vehicle speed is within the range of 05-1.0Km/h, the spray control system can achieve uniform coverage of coal transport vehicles and ensure that it does not affect the safety and normal operation of locomotives and vehicles.
