The invention provides an energy supply method. The method comprises the following steps: a renewable gas in a pneumatic compressor is compressed and then output as compressed gas; heat energy in the output compressed gas is extracted; the compressed gas of which the heat energy is extracted is pressurized and then fed into a first expander for expansion depressurization; expansion action of the renewable gas in the first expander is converted into energy output; and cold energy is extracted from the renewable gas which is subjected to expansion depressurization. The invention also provides an energy supply device used for the method. The energy supply device comprises a pneumatic compressor used for compressing renewable gases and provided with an exhaust port for discharging compressed gases, a first heat exchanger, a gas storage tank, a first expander, a second heat exchanger, and an output device used for converting gas expansion action in the first expander into energy output and connected with the first expander. According to the invention, surplus energy is recovered in the compression and expansion depressurization processes of the renewable gases and output as various types of energies.
Description
technical field [0001] The invention relates to an energy supply method and an energy supply device used in the method. Background technique [0002] The existing trigeneration technology scheme basically uses natural gas as the gas source. Natural gas is a non-renewable fossil energy, and there will be a certain amount of CO2 emissions during the combustion process. Moreover, the temperature of the gas after combustion is high, the requirements for the materials of the reactor equipment are relatively high, and the equipment cost and maintenance cost are relatively high. [0003] Specifically, the existing technical solutions generally combine a combined heat and power unit with an absorption refrigerator, use combustible gas such as natural gas as a gas source, and perform work through combustion and expansion to achieve energy output. Contents of the invention [0004] Aiming at the problems existing in the related art, the purpose of the present invention is to provid...
