The operating principle of blast drainage magnetization device for reducing dust:
Ordinary water is produced a large amount of anions by Permanentmagnet bar after entering pressure vessel by water inlet, one way valve, is able to elimination impurity through 80～120 order screen packs again; High-pressure blast is through air inlet port---and after one way valve enters pressure vessel, water is extruded by high-pressure rubber pipe, have the water smoke of negative electrical charge through the shower nozzle ejection of jet pipe parts.Because mine dust itself has positive charge, can catch the dust that has positive charge automatically after therefore having the water smoke ejection of negative electrical charge, increased greatly and caught dust quantity, produced splendid dust-laying effect.
The utility model has the advantages that:
1 this blast drainage magnetization device for reducing dust compact conformation, volume is little, and is in light weight, easy for installation, and not fragile, is convenient to the maintenance and management at scene, down-hole, can satisfy the on-the-spot needs of migration at any time, and each produces dirt pits and all can use, and the scope of application is extensive.
2 high-pressure blasts are atomized after water is sprayed, and the kinetic energy that the droplet that atomizing forms obtains is big, and atomizing effect is good, and the water smoke stroke is long, and the water smoke scope of formation is big, has increased dust-laying effect.
Can capture the dust that has positive charge automatically after 3 water smokes that have negative electrical charge spray, increase greatly and caught dust quantity (catch dust quantity and become hundred times increase), effectively suppress dirt source growing amount, produce splendid dust-laying effect (seeing the result of use table).
Communicating with each other of high-pressure blast and static pressure water avoided in the application of 4 one way valves; Be provided with 80～120 order screen packs in the pressure vessel, and can unpick and wash, stopped the shower nozzle clogging.
5 these device for reducing dust water supply volumes are little, saved dustproof water supply volume.
