How to reduce dust in coal mines?

Spray has good dust suppression and atomization effect, and the droplet diameter is only 3-5 microns, which is in the form of smoke and quickly melts into the air. The amount of humidification can be adjusted freely, which can reach the humidity in the air in a short time without dripping or condensation, so the machine and the ground will not be wet. The principle is that the surface tension of particles produced by spraying is basically zero because of their tiny size. When they are sprayed into the air, they can quickly absorb all kinds of dust particles in the air, thus forming effective dust control. It has good dust control and dust reduction effect in a large open area. At the same time, this effect is completely an atomization effect.

The main advantages are: the particle size of atomized water is particularly small, and it is easy to combine with dust particles to coagulate and settle, so its water consumption is greatly reduced compared with wet dust removal, which is only one thousandth or even less than that of traditional wet dust removal; The power consumption of the sprinkler is 0.02 kWh per hour, and the electricity expenditure is only 0.0 15 yuan. It can be seen that the operating cost of high-pressure spray is quite low.

I hope this helps.
