In the current era of pursuing green and sustainable development, energy innovation has become one of the key factors driving the development of various industries. As a traditional energy industry, how to use resources more efficiently and reduce the impact on the environment in mining has become one of the urgent problems that need to be solved. The technology scheme for utilizing waste heat from mine return air has emerged, injecting new vitality into energy innovation.
Working principle of mine return air waste heat utilization technology
The generation of waste heat from mine return air: During the mining process, a large amount of gas and heat is generated, and a part of it is discharged from the mine through the exhaust system, which is called return air. The high-temperature heat carried by this return air is a potential resource that can be efficiently utilized through reasonable technical solutions.
Principle of return air waste heat utilization technology: The return air waste heat utilization technology in mines mainly includes three stages: waste heat recovery, energy conversion, and reuse. By using waste heat recovery equipment, the high-temperature waste heat in the return air is captured and concentrated, and then converted into electricity or other forms of energy through energy conversion devices, which are then used for production and heating systems in mines.
