Problems solved by technology

For coal mining enterprises, although it is very convenient to burn the coal produced in the mine, at the same time, the coal-fired boilers used in coal mines have low efficiency and complicated management, and coal is a non-renewable energy source, which will cause environmental pollution after burning, which is not in line with the sustainable development of the country. strategy, which also reduces the coal that can be exported, reducing the profit of the enterprise
At present, there is no method and device for recovery and utilization of mine return air heat

Embodiment Construction

[0023] The solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] like figure 1 and figure 2 As shown, the mine return air heat recovery method of the present invention is provided with a bypass air duct in the air duct at the outlet of the return air shaft or in addition, and a heat exchanger is provided in the outlet air duct or the bypass air duct.

[0025] The heat recovery of the mine return air is used for the antifreeze of the shaft or the production or life of the mine. Mine return air heat recovery and utilization device, the heat exchanger method directly recovers mine return air heat. like figure 1 The implementation device shown mainly includes a regulating valve 7, a bypass air duct 8, a return air duct 9, a mine ventilator 10, a return air shaft 11, an air intake duct 12, and a double air duct type heat exchanger (heat exchanger) 13. On the air duct 9 at the outlet of the air...

Abstract

The present invention relates to a method for mine return air heat recovery utilization and its equipment. It is characterized by that in the air return well outlet airway or by-pass airway a heat exchanger is set, the described heat exchanger can be double flow channel type heat exchanger, heat-pipe type heat exchanger, rotary type heat exchanger, plate type heat exchanger or intermediate thermal medium heat exchanger.

Description

technical field [0001] The invention relates to the fields of mine ventilation technology, heat transfer technology and air conditioning technology. Background technique [0002] The mine ventilation system is an important system for mine production guarantee. At present, the general mine ventilation system is a central ventilation system, which uses a special air shaft to return air, and uses a fan to draw out the air and then directly discharge it into the atmosphere. Coal mines are generally mined underground. Because the temperature of the tunnel is high, reaching 30-40 degrees Celsius, even mine tunnels with higher temperatures are often encountered. Usually, the temperature will rise by about 3 degrees Celsius for every 100 meters below the constant temperature zone. , The temperature in the constant temperature zone is generally around 15 degrees Celsius. For example, the ground temperature of a mine 600 meters underground can reach about 30 degrees Celsius. When the...
