Exhaust steam recovery unit

The exhaust steam recovery device is based on the technical principles of vapor-liquid two-phase flow, liquid-liquid two-phase flow and venturi, through a complete set of precision automatic control devices, to recycle and recycle industrial exhaust steam energy-saving and environmental protection products. The reasonable installation and use of the device can not only effectively recover the exhaust steam and reuse it in the form of hot water to realize the cascade utilization of energy, but also reduce the thermal pollution and noise pollution to the environment, which is conducive to the implementation of energy saving and environmental protection.
