The invention discloses a mine thermal environment dehumidification and regeneration system and method. The mine thermal environment dehumidification and regeneration system and method are suitable for the high-temperature and high-humidity environment of an underground coal mine. The mine thermal environment dehumidification and regeneration system comprises a solution dehumidification device. The solution dehumidification device and a heating regeneration phase change device are connected with each other, and the heating regeneration phase change device is connected with the solution dehumidification device through a pipeline cycle and is further connected with a cooling device through a pipeline. The mine thermal environment dehumidification and regeneration system and method does not require the ground ambient air, is not affected by the underground thermal environment, effectively solves the technical problem of underground regeneration of a dehumidification solution, solves the problem that the discharge of the condensation waste heat of an underground refrigeration compressor is difficult, and achieves the efficient and reasonable utilization of the energy of a mine coolingsystem.
Description
technical field [0001] The invention relates to a mine thermal environment dehumidification regeneration system and method, and is especially suitable for the mine thermal environment dehumidification regeneration system and method used in the high-temperature and high-humidity environment of coal mines. Background technique [0002] With the deep mining, the problem of heat damage in mines has become more and more prominent, and the control of underground thermal environment (temperature, humidity) is becoming more and more important for safe and efficient production. [0003] At present, the underground thermal environment control method is cooling and cooling, which can also realize freezing and dehumidification while cooling the hot air. Liquid dehumidification systems are widely used in ground air conditioning systems, and air spraying is often used for regeneration. Due to the high temperature, high humidity and low moisture absorption capacity of underground air, it c...
