The invention discloses a heat exchange device for a low-temperature afterheat generator set. The heat exchange device for the low-temperature afterheat generator set comprises a dry evaporator and a full-liquid type evaporator connected through a pipeline, wherein a liquid viewing mirror and a liquid level sensor are mounted on a barrel body of the full-liquid type evaporator. The heat exchange device adopts the combined utilization of the dry evaporator and the full-liquid type evaporator to provide high-temperature and high-pressure steam to the low-temperature afterheat generator set, so that the heat exchange efficiency and the generating capacity of the set are improved.
Description
technical field [0001] The invention relates to a low-temperature waste heat power generation device, in particular to a heat exchange device for a low-temperature waste heat power generation unit. Background technique [0002] The low-temperature waste heat generator set is a device that converts low-grade heat energy into high-grade electrical energy. Since the temperature of low-grade heat energy is generally below 150°C, improving the conversion efficiency of heat energy is the key issue for improving power generation technology, and increasing the heat transfer area, reducing the heat transfer temperature difference and increasing the heat transfer coefficient of the thermal fluid are heat transfer technologies. key. [0003] The heat exchange of low-temperature waste heat generator sets has its particularity. The low-pressure and low-temperature liquid working medium condensed by the condenser becomes a high-temperature and high-pressure gaseous working medium. Accord...
