Mine Hidden Danger - Dust Control
One of the hidden dangers of mines is dust. How to achieve the treatment of mine dust? Please see the following introduction. The comprehensive dust suppression technology mainly includes key technologies such as bio-nano-film dust suppression technology, cloud dust suppression technology and wet dust collection technology. Bio-nano-film dust suppression technology, bio-nano film is a double-ionosphere film with nano-level spacing, which can maximize the ductility of water molecules and has strong charge adsorption; spray bio-nano film on the surface of materials. Attract and agglomerate small particles of dust to polymerize into large granular dust particles, and increase their own weight to settle; the dust removal rate of this technology is up to 99%, and the average operating cost is 0.05~0.5 yuan/ton. The cloud dust suppression technology is to produce ultra-fine dry mist of 1μm~100μm by high-pressure ion atomization and ultrasonic atomization; the ultra-fine dry mist particles are fine, fully increase the contact area with the dust particles, and the water mist particles collide with the dust particles and Coagulation, formation of agglomerates, agglomerates continue to become larger and heavier, until the final natural sedimentation, to achieve the purpose of eliminating dust; the resulting dry fog particles, 30% ~ 40% particle size below 2.5μm, pollution of atmospheric fine particles The control effect is obvious. The wet dust collection technology absorbs the air adhering to the dust by pressure drop, and removes dust under the dual action of centrifugal force and mixing of water and dust gas; the unique design of the unique impeller can provide higher dust removal efficiency. Suitable for bulk production, processing, transport, handling and other sectors, such as mining, construction, quarries, yards, ports, thermal power plants, steel plants, garbage recycling and other places.
