Mine return air complementary energy recycling system

Abstract

The invention relates to the technical field of mine ventilation equipment, and particularly relates to a mine return air complementary energy recycling system. The mine return air complementary energy recycling system comprises a fan, an air guide cylinder, a turbine and a generator; the fan is arranged on the air inlet side of the air guide cylinder; the generator is mounted in the exhaust side direction of the air guide cylinder; and the turbine is positioned between the air guide cylinder and the generator, and is mounted on an input shaft of the generator. The mine return air complementary energy recycling system can reduce the mine return air resistance and the kinetic energy loss, improves the return air energy recovery, conversion and utilization functions, and realizes the purpose of energy-saved utilization of mine return air through the horn-shaped air guide cylinder and by adding such matched facilities as the turbine, the generator, a slide bracket, a slide way and a propelling device. The mine return air complementary energy recycling system is skillful in structural design, convenient for construction, easy to manufacture, high in generality, easy to popularize and prominent in energy saving effect.

Description

technical field [0001] The invention relates to the technical field of mine ventilation equipment, in particular to a recovery and utilization system for residual energy of mine return air. Background technique [0002] As we all know, mine ventilation refers to the introduction of air into the mine to increase the concentration of oxygen in the mine and to remove harmful gases in the mine. The basic task of mine ventilation is to supply enough fresh air underground to meet the needs of personnel for oxygen, dilute toxic and harmful gases and dust underground, and ensure safe production. [0003] Most of the traditional mine return air shafts install a diffuser behind the air outlet of the fan, or build a diffusion tower to reduce the kinetic energy loss of the mine return air. The wind changes to a vertical upward wind direction, which has wind resistance and causes kinetic energy loss at the same time; in addition, because the mine return air volume is quite large, the mi...

Problems solved by technology

[0003] Most of the traditional mine return air shafts install a diffuser behind the air outlet of the fan, or build a diffusion tower to reduce the kinetic energy loss of the mine return air. The wind changes to a vertical upward wind direction, which has wind resistance and causes kinetic energy loss at the same time; in addition, because the mine return air volume is quite large, the mine return air discharged from the upper mouth of the diffuser also has a relatively high speed, that is, the mine return air contains greater kinetic energy was discharged
