| description | The utility model discloses complete equipment for comprehensively utilizing pressure energy of natural gas. The complete equipment comprises a gas inlet, an output port, a first heat exchanger, a second heat exchanger, a first gas-liquid separation tank, a second gas-liquid separation tank, a third gas-liquid separation tank and a fourth gas-liquid separation tank. A first ejector is connected onto a channel between the second heat exchanger and the first gas-liquid separation tank, a connecting channel is formed between the third gas-liquid separation tank and the second heat exchanger, a second ejector is arranged on the connecting channel, a branch of the gas inlet extends into a screw expander, and another channel of the gas inlet extends into a booster compressor of a natural gas liquefying plant; the booster compressor is connected with a circulating compressor in parallel, the converged natural gas from the circulating compressor and the booster compressor which are connected with each other in parallel flows into a precooling heat exchanger, the screw expander is provided with a user interface and a refrigerant interface, and the refrigerant interface is connected with the precooling heat exchanger. The complete equipment has the advantages that the complete equipment has power generation and natural gas liquefying functions, is high in comprehensive utilization rate of the pressure energy of the natural gas and further can be used for regulating peak loads of natural gas pipe networks, accordingly, stable natural gas supply can be guaranteed, and purposes of saving energy and protecting environments can be achieved. |
