The Analysis of the Cooling System with Gas-power-generation and Waste Heat Refrigeration
For the growing problem of mine heat hazard in the deep mining, according to the actual condition of the power source, this paper mainly analyzed the heat source of the Fourth Mine in Zhong ping Energy Chemical Group, and unprecedentedly adopted the waste heat from the gas power generation in the cooling of underground environment. The low temperature refrigerant of 5.2 ℃ is generated through a lithium bromide absorption chiller refrigeration system as the first-stage refrigerant, and the temperature of the refrigerant is further reduced to-3.4 ℃ by compressed chillers as the second-stage refrigerant. Through the main shaft, the refrigerant is transported to the high-pressure side of the high-low pressure heat exchangers inside the chamber which is located in the -320m level underground, finally, ethylene glycol solution is sent back to the ground for recycling after cold release. After the heat exchange, the 3 ℃ low temperature circulating water is transported to the air cooler installed in the machine Lane of the fully mechanized coal face by the cold water pump, which cools the inlet airflow on the working face to achieve the heat hazard control. The implementation of this cooling system, which has achieved significant economic, social and environmental benefit, have showed bright prospect for extended application.
