| description | The invention relates to the field of engineering thermodynamic refrigeration and low-temperature power generation, in particular to a multi-throat pipeline and turbine combined structure. The invention discloses a combined system design scheme suitable for effectively and reasonably utilizing pressure potential energy to generate electricity and supply cold to the outside in the natural gas pressure regulating process. In the design, a double-throat pipeline is matched with the low-temperature turbine in series, and an outer wall or inner pipe heat exchange device is mounted, so that the purposes of alternately performing accelerated cooling of a working medium in the pipeline and shock wave pressurization and finally driving the low-temperature turbine to generate power with relatively high pressure are achieved. A double-shock-wave flow field structure is creatively utilized, and meanwhile power generation and external cooling are achieved by fully utilizing pressure energy of a natural gas working medium. |
