The invention provides a system for energy matching based on liquefied natural gas, which comprises a storage tank set, a booster pump, a first compressor, a first heat exchanger and a first expander, wherein the storage tank set is used for storing liquefied natural gas; the booster pump outputs pressurized liquefied natural gas from the storage tank set; the first compressor is used for compressing air; the first heat exchanger is used for heating the liquefied natural gas outputted by the booster pump; the first expander is used for carrying out depressurization expansion gasification on the liquefied natural gas which is heated by the first heat exchanger; the first heat exchanger is provided with a first heat exchange passage and a second heat exchange passage; the first heat exchange passage allows the liquefied natural gas outputted by the booster pump to flow through; the second heat exchange passage is used for releasing heat to the liquefied natural gas in the first heat exchange passage when the compressed air outputted by the first compressor flows through the second heat exchange passage; and an energy transmission mechanism transmitting driving force to the first compressor is connected between the first compressor and the first expander; and work produced in expansion depressurization to the liquefied natural gas in the first expander serves as the driving force. The invention further provides a method for energy matching based on liquefied natural gas. The system and the method have higher energy utilization efficiency.
Description
technical field [0001] The invention relates to a method and system for energy matching based on liquefied natural gas. Background technique [0002] The existing technology is to use liquefied natural gas to depressurize and gasify, and the gasification gas directly enters the transmission pipeline and reaches the client. In a lower temperature environment, it is also necessary to consume energy (such as burning a part of fuel) to heat the gas. [0003] At present, the energy utilization rate of the traditional process of liquefied natural gas (such as LNG-liquefied natural gas) station is low, and heating energy may be required in a low temperature environment, which further reduces energy efficiency. [0004] The biggest problem of the current technical solution is that the liquefied natural gas is single-purpose, and a large amount of energy (such as pressure energy, cooling capacity, etc.) is lost in the process of decompression gasification.
