Bidirectional ventilation dust removal device for tunnel mining

Abstract

The invention discloses a bidirectional ventilation dust removal device for tunnel mining. The device comprises a jet flow fan and axial flow fan; a mount is installed under the jet flow fan; a ventilation duct is installed under the mount; a foot rest is installed under the ventilation duct; a support is installed at the side surface of the foot rest; a water tank is installed over the support; the axial flow fan is positioned at the left of the ventilation duct; an air strainer is installed at the right of the axial flow fan; a water collecting tank is installed under the air strainer; a water pump is installed over the water tank; a high pressure water pipe is installed over the water pump; an annular pipe is installed over the high pressure water pipe; a spray nozzle is mounted insidethe annular pipe. According to the bidirectional ventilation dust removal device for tunnel mining, a spray nozzle is arranged to spray water mist by cooperating with the water pump so that the dust in the dusty air combines with the water mist to form a dusty water mist to clean the dust in the air.

Description

technical field [0001] The invention relates to the technical field related to tunnel mining, in particular to a two-way ventilation and dust suppression device for tunnel mining. Background technique [0002] During tunnel construction, due to the explosion of explosives, the use of internal combustion engines and the excavation of the ground will cause more dust, and the air circulation inside the tunnel is not smooth when the tunnel is long, so special ventilation and dust suppression devices are needed, but the existing devices Ventilation alone is not effective in reducing dust. When sprinkler is used to reduce dust, the water flow will affect the surrounding mechanical equipment, waste water resources and affect the construction environment. [0003] In view of the above problems, an innovative design was carried out on the basis of the original dust suppression device for tunnel construction. Contents of the invention [0004] The purpose of the present invention i...
