Mine return airway transportation transfer points are important coal mine dust diffusion source, usually in order to prevent coal dust produced there, mainly to take manual spray sprinkler valves, water power, shutdown without water. However, this manual laborious, time consuming, expensive water, low efficiency. Mine Mining Group Company feicheng white young workers running small piecemeal reform work area to start, start from creating jobs drip innovation, low-cost alternative to the currently active, highly functional alternative to Improve Efficiency double double substitution activities, field fieldwork study, the use of solenoid valves in contact with a wire for coal flow, 

Additional delay circuit made of a method of intelligent modules, spray control system which can automatically determine the presence or absence of material, the valve opens automatically spraying, watering, to achieve in the case of coal flow spray valve opens automatically, NW; within the specified time to stop watering sustained no coal flow function, saving manpower, to achieve automatic control, not only prolong the life of the spraying device, but big in improving the economic efficiency of enterprises. Water valves, water power, shutdown without water. However, this manual laborious, time consuming, expensive water, low efficiency. Mine Mining Group Company feicheng white young workers work area running water valves, water boot, shutdown without water. However, this manual laborious, time consuming, expensive water, low efficiency. White Coal Mine Mining Group Company feicheng operation work area Young Workers 

The original use of traditional mechanical spray sprinklers one need only use a few hundred dollars a month, each belt conveyor spray device per year investment of nearly ten million, was transformed after the spraying device life of 2 years, the annual cost savings of nearly million.

BD in-line spray nozzle is mainly to used in  brine spraying, dust control, gas scrubbing, washing and cooling, metal treating and products degreasing.
