Mine dust removing apparatus and mine dust removing method

Abstract

The present invention discloses a mine dust removing apparatus and a mine dust removing method. The mine dust removing apparatus comprises a mineral conveying unit and a water vapor atomizing unit, wherein the mineral conveying unit comprises a high position conveyor, a first sealing soft curtain, a breaking inlet rolling channel, a breaking device, a mineral outlet, a connection rolling channel, a second sealing soft curtain and a low position conveyor, the high position conveyor, the first sealing soft curtain, the breaking inlet rolling channel, the breaking device, the mineral outlet, the connection rolling channel, the second sealing soft curtain and the low position conveyor are sequentially connected, the water vapor atomizing unit comprises a pressure gas source, a pressure water source, a spraying controller and four gas-water atomizing nozzles, one end of the spraying controller is connected to the pressure gas source and the pressure water source, the other end is connected to the four gas-water atomizing nozzles through a pressure gas pipeline and a pressure water pipeline, the two gas-water atomizing nozzles are arranged on the upper end of the breaking inlet rolling channel, the spraying direction is along the mineral conveying direction, the other two gas-water atomizing nozzles are arranged on the lower end of the connection rolling channel, and the spraying direction is opposite to the mineral conveying direction. With the apparatus and the method of the present invention, the problems of not strong practicality and easy secondary pollution formation of the existing dust removing apparatus and the existing dust removing method can be effectively solved, and advantages of simpleness, reliability, environmental pollution avoiding and the like are provided.

Description

technical field [0001] The invention belongs to the field of dust removal devices and methods, and more specifically relates to a mine dust removal device and method. Background technique [0002] In mining, beneficiation, raw ore coarse crushing, fine crushing pretreatment and other production links, due to the crushing of raw ore, the volume changes, which will inevitably produce fine raw ore particles and dust, causing a large amount of ore dust to diffuse into the working space, forming mine dust Pollution and hazards, often because the mine dust hazards generated in the above-mentioned production links cannot be eliminated in a timely, accurate and comprehensive manner, and measures have not been taken in time, resulting in the phenomenon that the dust pollution on the work site seriously exceeds the standard, which seriously damages the health of the on-site workers It also causes pollution to the adjacent working environment, and mine dust pollution is very prone to m...
