The mining industry occupies an important position in the national economy, but at the same time, it also faces problems such as high energy consumption and serious environmental pollution. In order to achieve sustainable development of mining production, energy conservation and emission reduction have become the top priority. In this context, the lack of wind heat recovery technology has emerged as an important tool for energy-saving transformation in mining.
As a high-energy consuming industry, mining has a huge demand for energy in its production process, such as electricity, fuel, etc. At the same time, the ventilation system in mines is an indispensable part of mining production, but the problem of lack of air in the ventilation system has always plagued mining enterprises. The traditional method of dealing with exhaust often wastes a large amount of thermal energy resources, which cannot achieve effective utilization of resources and also increases the energy cost of enterprises.
On the other hand, the waste heat, exhaust gas and other resources generated in the mining production process, if not effectively utilized, not only result in energy waste, but also bring certain pollution pressure to the environment. Therefore, how to achieve energy conservation and resource utilization in the mining production process has become a serious challenge facing the current mining industry.
The exhaust heat recovery technology is a technology that utilizes the exhaust heat energy in the mine ventilation system and recovers it for reuse through a heat exchange device. Specifically, exhaust heat recovery technology can be divided into two ways: direct utilization and indirect utilization.
Direct utilization: Directly apply the exhausted wind heat energy to the heating, hot water supply and other fields near the mine surface to meet the thermal energy needs of production and life, and achieve the goal of energy conservation.
Indirect utilization: By using heat pumps and other equipment to raise the temperature of the exhaust heat energy, it can be reused, such as for heating, drying and other processes inside mines, in order to achieve effective energy utilization and energy conservation and emission reduction.
The advantages of exhaust heat recovery technology are mainly reflected in the following aspects:
Energy conservation and emission reduction: Effectively utilizing the exhaust heat energy in the mine ventilation system, reducing reliance on traditional energy, and reducing energy consumption and carbon emissions.
Resource utilization: The recovery and reuse of exhaust heat energy has achieved the regeneration and utilization of waste heat resources, reduced energy waste, and improved resource utilization efficiency.
Cost reduction: Through the use of exhaust heat recovery technology, mining enterprises can reduce energy costs in the production process and improve economic benefits.
Improving the environment: reducing exhaust emissions, reducing the impact on the environment, and promoting green development of mining production.
The exhaust heat recovery technology, as a new technology for energy-saving transformation in mining, is of great significance for improving mining production efficiency, reducing energy costs, and improving environmental quality. Mining enterprises should actively introduce and promote exhaust heat recovery technology, increase technological innovation and application efforts, and contribute to the sustainable development of the mining industry. In the future development, exhaust heat recovery technology will play an increasingly important role in the field of energy conservation and emission reduction in mining, achieving green and low-carbon development of mining production.
