Dust removal equipment for mining

By installing atomizers and turbulent flow fields in dust removal equipment used in mining operations, dust and water droplets collide to form condensation nuclei, and mud lumps are removed using fences and scrapers. This solves the problems of poor purification effect and filter clogging of small-particle-size mineral dust in high-humidity environments, achieving efficient dust removal and stable equipment operation.

AI Technical Summary

Technical Problem

Existing dust removal equipment used in mining operations is ineffective in handling small-particle, hygroscopic, and agglomerated mineral dust in high-humidity environments, resulting in poor purification performance and easy clogging of filters.

Method used

Atomizers are installed inside the pipes to spray high-concentration water mist, forming a uniform water mist field. This causes fine dust particles to collide with water droplets to form condensation nuclei. Turbulent flow fields promote high-frequency collisions between dry dust particles and condensation nuclei. A grid is used to intercept the condensed mud clumps, and a scraper is used to remove the attached mud clumps, achieving efficient interception and cleaning.

Benefits of technology

It achieves efficient interception and removal of small-particle-size hygroscopic agglomerated mineral dust in high humidity environments, avoids filter clogging, and ensures long-term stable operation of dust removal equipment.

Abstract

The embodiment of the invention discloses dust removal equipment for mine mining, which is applied to the technical field of mine environmental engineering and comprises a pipeline, a fence, an atomizer and a fan, the fence is arranged in the pipeline, the atomizer is positioned between an air inlet of the pipeline and the fence, the fan is connected with the air inlet of the pipeline, and the fan adopts turbulent flow type blades. The atomizer forms a high-concentration uniform water mist field, so that fine dust and water drops are combined under the action of Brownian motion and inertial collision to form wet condensation nucleuses, then a turbulent flow field is formed in the pipeline through the fan, free dry dust particles, tiny liquid drops and the formed condensation nucleuses are subjected to high-frequency collision, mutual adhesion and condensation are achieved, and the dust removal effect is achieved. And a fence is arranged at the downstream of the atomizer to intercept agglomerated and formed clods, and clean airflow is discharged through air outlets through holes of the fence, so that accurate trapping and efficient interception of respirable dust are realized.
