How to improve the effectiveness of spray dust reduction system?

Spray dust-removing system is a means of wet dust removal. Using the principle of fine water atomization, the mist sprayed in the air produces negative ions and binds with a large number of positive ions in the dust. When the diameter of the droplet particles and the dust particles are close to each other, they will adhere to each other, and settlement will occur after weight gain. Suppression of dust diffusion, so as to achieve the purpose of dust reduction. The spray dust suppression system has a wide range of applications and is mainly used for construction sites, various types of mixing stations, various types of industrial and mining stockyards, and engineering roads.

With the continuous application of spray dust reduction systems in various fields, how to maximize the use of spray dust reduction systems? What factors may affect the use of spray dust?

Through practical experience summarizing and improving the effectiveness of the spray dust suppression system, the following factors need to be carefully considered:

1, water mist particle size

Primacy, the decisive factor. If the ratio of water mist particles to dust particles cannot reach the critical value, there will be elastic collision between the two, just as if a table tennis ball hits a basketball. It does not play a role in dust reduction, or the efficiency of dust reduction is greatly compromised.

2, dust or smoke temperature

When the dust-falling site temperature is high, the sprayed water mist first needs to be cooled, and if the temperature is not reduced to a certain level, the dust-falling effect will not be achieved, and the steam generated during the cooling of the mist by the muck will also be brought upward. Smoke and dust.

3, the number of nozzles

The number and layout of nozzles must be reasonable; otherwise, no good dust-reducing effect can be achieved.

4, the amount of water spray

The amount of water should be sufficient and appropriate. The amount of water sprayed is a waste of water resources, and it is not conducive to steam recovery and increasing the temperature of the recovered water. If the amount of water sprayed is small, the efficiency of dust reduction cannot be fully guaranteed.

In addition, the need to properly select a spray dust-reduction system based on the construction site requirements is also critical. If the selected spray system is not suitable for the actual needs of dust reduction, it will also affect the dust reduction effect. The spray dust reduction system can be divided into high-pressure spray dust-reduction systems, low-pressure spray dust-reduction systems, and remote spray gun dust-reduction systems according to different application fields.
