Abstract

The invention discloses a power generation device capable of increasing the static pressure of a fan to recover mine return air flow energy. The power generation device comprises a wind tunnel, one end of the wind tunnel is connected with the fan, the fan and a return air well opening are correspondingly installed, the other end of the wind tunnel is bent upwards and provided with a wind energy converter in a matched mode, the input end of the wind energy converter is connected with a wind wheel located at an outlet of the wind tunnel, and the wind wheel is connected with a generator set through the output end of the wind energy converter. The wind energy converter comprises an input shaft, a lower support is rotationally installed at the lower end of the input shaft, and the wind wheel and the input shaft are integrally installed and located above the lower support. An upper support is rotatably installed in the middle of the input shaft, and an annular supporting beam connected with the other end of the wind tunnel is installed between the lower support and the upper support. Through the wind tunnel, the wind wheel, the wind energy converter and the generator set, one part of the mine return air flow energy is recycled and converted into electric energy, and the other part is converted into static pressure energy of the wind wheel.

Description

technical field [0001] The invention relates to the field of coal mine safety production, in particular to a power generating device for increasing the static pressure of a fan to recover the energy of the mine return air flow. Background technique [0002] Due to the existence of dust and harmful gases in the former coal mine production, the mine must be ventilated to remove and dilute. The outlets of the wind tunnels are all rectangular. The air velocity at the outlet is generally 6 m / s, and the air volume of each return air shaft is generally 100. It is about cubic meters per second, and each return air shaft works throughout the year, 24 hours a day without interruption, and the fan needs to increase the static pressure to improve the fan's ability to overcome the resistance of the underground roadway. Energy recovery has great potential and important significance, so there is an urgent need for a device that can recover energy from the return air flow and increase the s...
