Organic Rankine generator set

The utility model discloses an organic Rankine generator set, which comprises an evaporator, an expander, a condenser, a liquid storage tank and a refrigerant pump, the liquid storage tank is arrangedat a position higher than the refrigerant pump, a refrigerant is arranged in the liquid storage tank, and the height difference between the refrigerant liquid level in the liquid storage tank and theinlet of the refrigerant pump is not less than 2m. A refrigerant liquid column which is not shorter than 2m is formed between the refrigerant liquid level of the liquid storage tank and the inlet ofthe refrigerant pump, pressure generated at the bottom of the refrigerant liquid column with the length is enough to inhibit generation of a refrigerant gas phase in the refrigerant pump, and the cavitation phenomenon of the refrigerant pump is effectively inhibited. 本实用新型公开了一种有机朗肯发电机组，其包括蒸发器、膨胀机、冷凝器、储液罐和冷媒泵，储液罐设置在高于冷媒泵的位置，储液罐内设有冷媒，储液罐内的冷媒液面与冷媒泵的入口之间的高度差不小于2m。在储液罐的冷媒液面与冷媒泵的入口之间形成了不短于2m的冷媒液柱，该长度的冷媒液柱底部所产生的压力足以抑制冷媒泵内生成冷媒气相，有效
