Установка рекуперации тепла для вентиляции шахты
In cold-region mines, vast volumes of ventilating exhaust air (2–15 °C) are discharged while fresh intake air must be heated to prevent shaft freezing. A mine ventilation heat recovery unit transfers that waste heat to the intake air.
Why not rotary in mines
Exhaust air is dusty and humid; a rotary wheel clogs and cross-contaminates. Use plate or heat-pipe exchangers — isolated streams, washable, no moving parts.
Преимущества
- Shaft freeze protection: pre-heat intake air in winter.
- Fuel savings: cut heating cost 20–40%.
- Безопасность: stable underground climate.
