With the continuous growth of energy demand and the improvement of environmental protection awareness, the efficient utilization and recycling of energy has become an important issue in various industries. In the mining industry, especially during the mining process, a large amount of exhaust and waste heat resources are not effectively utilized, resulting in energy waste and environmental load. However, with the development and application of waste heat recovery technology, a new era of energy reuse in mines has arrived.
During the mining process, a large amount of exhaust air and waste heat are often generated. Lack of air refers to the air flowing inside a mine, which often has a higher temperature and pressure than the external environment. However, due to the lack of effective utilization methods, most of the lack of air is discharged into the atmosphere, resulting in energy waste and environmental pollution. At the same time, a large amount of waste heat is generated during the mining process, such as mine drainage, ventilation systems, mechanical equipment, etc. However, these waste heat resources are often overlooked and not effectively utilized.
The technology of waste heat recovery from exhaust air refers to the effective recovery and utilization of waste air and waste heat resources inside mines through various thermal energy conversion equipment. It mainly includes the following technologies:
Heat pump technology: Using the principle of heat pumps, low-temperature exhaust and waste heat energy are converted into high-temperature heat energy for heating, hot water, and other purposes.
Heat exchange technology: By using a heat exchanger, the waste heat in the mine drainage and ventilation system is transferred to the medium that needs to be heated, achieving energy reuse.
Power generation technology: Utilizing the exhaust air and waste heat inside the mine, generating electricity through generator sets to meet the power demand of the mine while reducing external energy dependence.
With the continuous development and application of waste heat recovery technology, a new era of mining energy reuse has arrived. In the future, we can look forward to:
Technological innovation: With the continuous progress of technology, the technology of waste heat recovery from exhaust air will continue to be updated, improving energy utilization efficiency and economy.
Policy support: Increase support for energy reuse technology and promote the widespread application of waste heat recovery technology in the mining industry.
Industry cooperation: Mining enterprises will engage in deep cooperation with energy technology companies, research institutions, and others to jointly promote the application and development of waste heat recovery technology in the mining industry.
In the context of the new energy era, the application of exhaust heat recovery technology will inject new vitality into mining production, promote sustainable development of mining, and achieve a virtuous cycle of economic, environmental and social benefits.
