Abstract
Description
Technical Field
[0001] The present application relates to the field of dust removal devices, and in particular to a tunnel blasting dust removal device. Background Art
[0002] Tunnel blasting operations generate high dust concentrations, fine particles, and extremely slow natural settling rates, hindering shortening operation cycle times. Currently, foam dust removal devices are often used to reduce dust concentrations before blasting operations. These devices offer excellent isolation, large contact area, rapid wetting, and excellent adhesion, effectively preventing and controlling blasting dust hazards. However, since foam contains moisture, it tends to accumulate at the nozzles during foam delivery and fall to the ground, resulting in waste. Furthermore, this moisture can easily make the ground muddy, making it unusable. Therefore, a tunnel blasting dust removal device has been proposed. Utility Model Content
