In the era of energy scarcity and increasing environmental pressure, as an important field of energy extraction, how to fully utilize the waste heat of exhaust air and improve energy recovery efficiency in mines not only helps to reduce operating costs but also reduces environmental burden.

As an efficient energy conversion technology, heat pump technology can convert low-temperature exhaust heat into high-temperature heat energy, achieving effective energy recovery. By applying efficient heat pump systems, low-temperature heat can be raised to a sufficiently high temperature for use in various fields such as heating and production. The application of heat pump technology can not only reduce the waste of exhaust heat energy, but also provide stable energy supply for mines.

Mines usually generate various forms of energy, such as electricity, gas, etc. Through multi energy cogeneration technology, different forms of energy can be integrated to achieve complementary energy utilization. For example, combining electricity with heat pump technology to convert electrical energy into thermal energy and achieve optimal energy allocation. This method can not only improve the recovery efficiency of waste heat from exhaust air, but also greatly utilize the advantages between different energy sources.

A thermal storage system is a technology that can store thermal energy during low periods and release it during peak periods. In the recovery of waste heat from mine exhaust air, a heat storage system can be applied to store the heat energy during low periods and release it when heating is needed during peak periods, thus achieving efficient energy utilization. The application of heat storage systems can not only improve the efficiency of heat recovery, but also adapt to the changes in demand during different energy consumption periods.

The construction of intelligent control and monitoring systems is particularly important in the process of recovering waste heat from mine exhaust air. By monitoring the temperature, flow rate, and other parameters of exhaust heat in real-time, it is possible to accurately grasp the energy utilization situation, adjust system operating parameters in a timely manner, and achieve good energy efficiency. The intelligent control system can also automatically adjust the operating mode of the heat pump system based on actual energy needs, ensuring efficient energy utilization.

The recovery of waste heat from mine exhaust air should be considered from the perspective of overall planning, taking into account the comprehensive utilization of waste heat. For example, the waste heat recovery system of exhaust air can be integrated with other energy systems to achieve energy sharing and complementarity. At the same time, the waste heat recovery system can also be connected to industrial parks, residential areas, etc. to achieve cross-border utilization of waste heat and maximize the value of waste heat.

Improving the efficiency of waste heat recovery from mine exhaust air cannot be achieved without talent training and technical support. The mine needs a team with professional knowledge in exhaust air and waste heat recovery technology, capable of proficiently operating and maintaining relevant equipment. At the same time, it is also necessary to establish cooperative relationships with relevant scientific research institutions and enterprises, obtain technical support and innovative solutions, and continuously improve energy recovery efficiency.

The recovery of waste heat from mine exhaust air is an important task that can achieve efficient energy utilization and reduce environmental burden. By applying efficient heat pump technology, multi energy cogeneration technology, heat storage systems, and other means, combined with the construction of intelligent control and monitoring systems, as well as the overall planning of waste heat comprehensive utilization, the efficiency of waste heat recovery can be effectively improved. In addition, talent training and technical support are also key factors in improving efficiency. Through continuous exploration and innovation, the waste heat recovery technology of mine exhaust air is expected to become a highlight of the energy industry and contribute to sustainable development.
