Problems solved by technology

[0004] However, the overall height of the existing air guiding device is mostly very high, which is not convenient for staff to overhaul
At the same time, most of the waste heat recovery devices are installed in mining areas, and the surface of the mining area is mostly uneven, which leads to shaking of the air guide device during operation, and there is a risk of accidental leakage of mine return air

Abstract

The invention provides a mine return air guiding device for guiding the discharge of return air of a mine. The mine return air guiding device comprises an air introducing cylinder installed at an airguiding cylinder of a mine mouth in an upward extending mode and an air guiding cylinder communicating with the air introducing cylinder, the air guiding cylinder is horizontally arranged and is connected to the ground through support rods, the air introducing tube and the mine mouth are in tight coupling, and the air guiding tube and the air introducing tube are in tight coupling.

Description

technical field [0001] The present invention generally relates to the technical field of mining, and in particular, relates to a mine return air guiding device. Background technique [0002] For the underground mining industry, underground ventilation is essential, and the wind discharged from the underground is generally referred to as mine return air. The mine return air brings out the heat from the strata hundreds of meters below in the form of sensible heat and latent heat, which contains considerable heat energy. [0003] In the prior art, a waste heat recovery device is often used to recycle mine return air. In order to make the waste heat recovery efficiency of the mine return air higher, the setting of the air guide device is particularly important. [0004] However, the overall height of the existing air guiding device is very high mostly, which is not convenient for staff to overhaul. At the same time, most of the waste heat recovery devices are installed in min...
