The harm of body is especially big, is to cause pneumoconiosis and the main contributor of atmosphere pollution, seriously threatens the health and lives of the mankind.
Suppressing dust with dry mist technology, is that water smoke is melted into ultra-fine droplet, and when dust-contained airflow bypasses droplet, grit is due to inertia meeting
From the air-flow streamed deviate and with droplet bump against be captured, i.e., by the inertial collision of powder dust particle and drop, intercept and
The effects such as cohesion, diffusion, which are realized, to be caught so that the particle diameter of grit becomes big, settles down under gravity, reaches gumming
The purpose of grit.If droplet particle diameter is much larger than dust granules, then dust only follows the gas around water fog particle
Stream motion, water fog particle is contacted seldom with dust granules or is not in contact with all, and does not reach dust suppression effect.Therefore, droplet
The whether sufficiently small effect for determining suppressing dust with dry mist of diameter.Dry fog machine is the core component of suppressing dust with dry mist equipment, existing dry fog
