Coal Storage Yard Dust Control

Coal storage yards are generally open-air, and the coal dust generated during the stacking, loading and unloading of coal will pollute the surrounding air.

First of all, the prevention and control of coal pile dust. The coal yard has a large storage capacity, fast operation speed, and fast renewal speed of the surface of the coal pile, and the prevention and control measures should be based on the principle of convenience and economy, and spray water is adopted to suppress the spread of coal dust. When spraying, the diameter of water droplets is controlled above 40um, and the water droplets are too small to evaporate and affect the effect; The injection device should be arranged according to the shape, volume, wind direction, performance of the injection device and other conditions of the coal stacking to ensure that the spraying coverage reaches 100%, and the height is generally controlled at 1.5m.

RELAB supplies a wide range of nozzles and equipment for the control of coal yard dust. Spray dust reduction can be with the help of high-pressure mist nozzles. The water droplets ejected can be combined with dust to promote inert condensation of dust and play a condensing effect. In this process, the water mist particles can be combined with the dust particles through inertial collision, so that the dust particles are in a wet state, and the dust particles settle by increasing the weight, and finally achieve the dust removal effect. In order to present a better dust reduction effect, it is necessary to ensure that the nozzle is formed to achieve the mist flow effect. This technology is one of the main ways to control dust concentration in mine air, and can be applied in the transportation industry, mining work and offloading work.

Dust reduction can also be carried out by dust suppression fog cannon. There are fixed, lifting, tower type, vehicle-mounted type and various forms to choose from, especially suitable for thermal power generation, cement, chemical industry, coal, mines, construction sites, demolition sites, concrete batching plants, railway and highway construction sites and other outcropping coal, ore yard wind and dust pollution control.
