Application of waste heat utilization technology for surface main ventilator in underground coal mine
LI Xiaofeng
Abstract：Taking the waste heat and energy utilization system of the surface main fan in Shangwan Coal Mine as an example,the technology of the waste heat and energy utilization system of the surface main fan in the mine is deeply studied.The system components,the specific structure of the function realization and the system working principle are described.The characteristics of the system which can efficiently utilize the waste heat of the exhaust fan and realize the reuse of heat energy are highlighted,so as to improve the energy utilization efficiency.Around the current system power supply technology,the new power supply technology of the waste heat and energy utilization system of the surface main fan in the mine is proposed.The economic benefits of the new power supply technology and the problems and difficulties in its application are analyzed.The economy of the system is compared and analyzed in terms of cost,coal consumption and pollutant emission.It provides reference for the technical transformation of the exhaust heat and heat utilization system of the mine ground main fan.
