Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] In order to suppress the cavitation phenomenon of the refrigerant pump and improve the service life of the refrigerant pump, the invention provides an organic Rankine generator set.

[0032] Please refer to figure 1 and 2 As shown, in various embodiments of the present invention, the organic Rankine generator set includes an evaporator 1 , an expander 2 , a generator 3 , a condenser 4 , a liquid storage tank 5 and a refrigerant pump 6 . The refrigerant side of the evaporator 1, the expander 2, the refrigerant side of the condenser 4, the liquid storage tank 5 and the refrigerant pump 6 are sequentially connected in a closed loop to form a refrigerant circulation loop. The outlet of the liquid storage tank 5 is connected to the inlet of the refrigerant pump 6 through a pipe 7. The liquid storage tank 5 is set at a position higher than the refrigerant ...

Abstract

The invention discloses an organic Rankine generator set which comprises an evaporator, an expansion machine, a condenser, a liquid storage tank and a refrigerant pump; the liquid storage tank is arranged at a position higher than the refrigerant pump; a refrigerant is arranged in the liquid storage tank; the height difference between the liquid surface of the refrigerant in the liquid storage tank and the inlet of the refrigerant pump is equal to or greater than 2 m; a refrigerant liquid column no less than 2m is formed between the liquid surface of the refrigerant in the liquid storage tankand the inlet of the refrigerant pump; and pressure generated at the bottom of the refrigerant liquid column is sufficient to restrain generation of a refrigerant gaseous phase in the refrigerant pumpso as to effectively restrain the cavitation phenomenon of the refrigerant pump.

Description

technical field [0001] The invention relates to the field of waste heat power generation, in particular to an organic Rankine generator set. Background technique [0002] In organic Rankine power generation, the refrigerant is cooled and pumped by the refrigerant pump to the evaporator for heat exchange. Refrigerant liquid can easily cause cavitation when passing through the refrigerant pump, and long-term operation will damage the operating life of the refrigerant pump and system stability. Contents of the invention [0003] In order to suppress the cavitation phenomenon of the refrigerant pump and improve the service life of the refrigerant pump, the present invention provides an organic Rankine generator set, including an evaporator, an expander, a condenser, a liquid storage tank and a refrigerant pump, the outlet of the liquid storage tank and the The inlet of the refrigerant pump is connected by a pipeline, and the liquid storage tank is set at a position higher tha...
