In the process of coal mine production, waste heat from exhaust air has always been regarded as a waste of energy. However, with the continuous progress of technology and the improvement of environmental awareness, the recycling and utilization of waste heat from coal mine exhaust air is becoming an important energy regeneration and utilization technology.
The coal mine exhaust heat recovery technology is the process of capturing and utilizing the waste heat from the high-temperature flue gas discharged from the coal mine. Different technical methods can achieve different recycling goals, and the following are some common recycling technologies:
Heat exchanger technology: Utilizing a heat exchanger to exchange heat between the discharged high-temperature flue gas and the fluid that needs to be heated, achieving energy transfer and achieving the effect of energy recovery.
Power generation technology: Through waste heat power generation technology, the waste heat of exhaust air is converted into electrical energy, achieving energy regeneration and utilization. This technology can convert waste heat into usable energy and provide electricity support.
Heating and heating technology: Using waste heat from exhaust air for heating and heating, providing clean and renewable heat energy to surrounding areas, and reducing energy costs.
Steam generation technology: Utilizing waste heat from exhaust air to generate steam, which is used to meet the steam demand in industrial production processes and improve energy utilization efficiency.
The Ordos Zhuanlongwan Wind Well Site Exhaust Air Heat Extraction Project is located in Ordos City, Inner Mongolia Autonomous Region. In order to fully utilize the waste heat energy of mine exhaust air, comply with the development trend, and deepen the implementation of environmental protection reform measures, the project applies Kcalin exhaust air heat pump units for clean energy heating, providing users with a comfortable and clean heating experience, and achieving rational energy utilization.
The recovery of waste heat from coal mine exhaust not only contributes to the regeneration and utilization of resources, but also brings rich economic and environmental benefits:
Reducing energy costs: By effectively utilizing waste heat, energy expenditure can be reduced and production efficiency can be improved.
Reducing environmental pollution: Effectively recovering waste heat can reduce the emission of harmful gases, reduce the load on the environment, and achieve environmental protection goals.
Increase revenue sources: Technologies such as waste heat power generation and heating can not only meet the internal energy needs of mines, but also create additional revenue sources for enterprises.
