Description

Micron-sized dry fog dust suppression system

Technical Field

The invention belongs to the technical field of dust suppression equipment, and particularly relates to a micron-sized dry fog dust suppression system.

Background

The micron-sized dry mist dust suppression principle is based on the research theoretical achievement of European and American scientists, namely that the probability of adsorption, filtration and condensation is the maximum when the sizes of water mist particles and dust particles are close. When a gas stream containing dust particles bypasses the mist droplets, the probability of the mist droplets catching the dust particles in the gas stream is related to the diameter of the mist droplets. When the droplets are large, the dust particles simply bypass the droplets with the airflow and are not captured. When the particle size of the fog drops is close to that of the dust, the fog drops are easier to collide with each other to capture the dust particles. The micron-sized dry mist is just to generate mist drops with the particle size of less than 5 microns and close to that of superfine dust by applying the principle to effectively capture the dust. And because the fog drops are fine, part of the fog drops can be quickly evaporated in the air, so that the relative humidity in a local space is quickly saturated, the saturated water vapor can be condensed by taking dust particles as nuclei, the diameter of the dust particles is continuously increased until the dust particles fall down, and the effect of dust suppression is achieved.

At present, in use, a micron-sized dry fog dust suppression system is provided with a micron-sized dry fog nozzle at a specific position of a processing line, dry fog is continuously output to reduce dust, the output of the dry fog cannot be regulated according to actual dust concentration, the dry fog concentration is excessive or the dust suppression effect is insufficient due to excessive dust concentration in a certain section of area, and therefore the design needs to be improved in a targeted manner.
