Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to an ionized spray dust removal system. Background Art

[0002] Mine dust is a general term for solid fine particles produced during coal production. In many links such as mine production, coal storage, coal transportation and tunnel excavation, a large amount of dust is emitted into the air underground, which has a negative impact on safety, health, environment, etc. In the existing technology, there are generally two dust removal methods for these dusts: wet dust removal and dry dust removal. Among them, the wet dust removal process system is simple, safe and reliable, and has strong adaptability to the complex environment of mines, so it is more widely used.

[0003] However, in coal mines, the dust concentration is often very high. For these high-concentration dusts, although increasing the spray flow rate can improve the dust reduction efficiency to a certain extent, the improvement effect is very limited. It not only wastes water resources, but is also limited by the size of the atomized particles, resulting in less than ideal dust reduction effects. Utility Model Content

[0021] (III) Beneficial effects

[0023] 1. In this ionization spray dust removal system, air enters from the air inlet of the box.

[0024] 2. The ionized spray dust removal system uses a needle-shaped electrode to make the dust particles carry a negative charge.
