Recover All Usable Heat from Ventilation
The Mine Vent Air Heat Recovery Unit is designed for mine ventilation systems. It recovers usable heat from exhaust air and integrates filtration, heat exchange, and cleaning into a single system. The equipment is engineered to handle the high-dust environment typical of mines.
The exhaust air temperature ranges from 15℃ to 25℃ and remains relatively stable throughout the year. The equipment is designed to operate reliably without clogging under dusty conditions.
Large Air Volume Handling
The exhaust air volume ranges from 100,000 to 500,000 cubic meters per hour. The heat exchange efficiency is 60% to 75%. The fresh air preheating temperature increase is 8℃ to 15℃. The air-side resistance is below 150 Pa.
The system uses heat pipe or plate-type heat exchangers. Fan power is selected to match the required air volume. The Mine Vent Air Heat Recovery Unit is designed to handle large-scale mine ventilation systems.
Key Advantages and Online Cleaning
The key feature of this ventilation heat recovery system is its integrated online cleaning function. Mine exhaust air typically contains a high level of dust, which can easily cause clogging in conventional heat exchangers.
Our system is equipped with an online cleaning mechanism that allows continuous operation without shutdown for maintenance. This significantly reduces operational downtime.
We have been in business since 1996 and have extensive experience in waste heat recovery systems. We have implemented multiple main fan exhaust heat recovery projects in coal mines. The recovered heat is used to preheat intake air, significantly reducing energy consumption for shaft freeze protection and ventilation heating.
The Mine Vent Air Heat Recovery Unit delivers substantial energy savings and improved operational efficiency.
