Abstract

The invention discloses a mine underground cooling and waste heat recycling system. The mine underground cooling and waste heat recycling system comprises a mounting plate which is arranged on the upper end of a mine frame arranged in a mine channel, a heat exchange shell which is arranged at the top end of the mine frame, a driving structure which is fixed to the heat exchange shell, a waste heat boiler arranged in the heat exchange shell, an air draft structure arranged on one side of the heat exchange shell, an air outlet structure which is arranged on the side wall of the mine frame, a heat exchange pipe which is wound on the waste heat boiler and arranged with one end connected with the air draft structure and the other end connected with the air outlet structure, a filtering structure which is arranged on the mounting plate and arranged between the other end of the heat exchange pipe and the air outlet structure, and a steam turbine which is connected with the waste heat boiler. The cooling and waste heat recycling system is convenient for operation and high in cooling efficiency, collected heat energy assists in power generation, underground waste heat energy of a mine can be well recycled, and production energy consumption and cost in the mine are reduced.

Description

technical field [0001] The invention belongs to the technical field of mine equipment, and more specifically relates to a mine well cooling and waste heat recovery and utilization system. Background technique [0002] With the increasing depth of mine mining and the continuous improvement of mining mechanization, high-temperature heat damage in deep mines has become one of the major problems restricting the safe mining of coal mines. Affect the health and life safety of employees. At present, the mine cooling measures mainly include non-artificial cooling and artificial cooling. Among them, non-artificial cooling is usually achieved by using or increasing ventilation, and artificial cooling requires Higher energy consumption is consumed to provide cooling load. In addition, mine cooling and heat removal need to be achieved by means of mine return air, mine drainage, or setting up cooling towers on the ground. [0003] However, the waste heat in existing underground mines ca...
