CO2 GAS-LIQUID PHASE TRANSITION-BASED MULTISTAGE COMPRESSION ENERGY STORAGE APPARATUS FOR CONVERTING THERMAL ENERGY INTO MECHANICAL ENERGY
Document Type and Number:
WIPO Patent Application WO/2022/166391
Kind Code:
A1
Abstract:
A CO2 gas-liquid phase transition-based multistage compression energy storage apparatus for converting thermal energy into mechanical energy, comprising: a gas storage (100); a liquid storage tank (200); an energy storage assembly (300), which comprises a condenser (350) and at least two compression energy storage parts, which comprise compressors (310 and 330) and energy storage heat exchangers (320 and 340); an energy release assembly (400), which comprises an evaporator (410) and at least one expansion energy release part, which comprises energy release heat exchangers (420 and 440) and expanders (430 and 450); a heat exchange assembly (500), the energy storage heat exchangers (320 and 340) and the energy release heat exchangers (420 and 440) being connected to the heat exchange assembly (500), the energy storage heat exchangers (320 and 340) temporarily storing in the heat exchange assembly (500) the energy generated by the energy storage assembly (300), and the energy release heat exchangers (420 and 440) being capable of receiving the energy temporarily stored by the heat exchange assembly (500); and a driving assembly (800), which comprises an energy input member (810) and a first driving member (820), the energy input member (810) absorbing external thermal energy to drive the first driving member (820) to work, and the first driving member (820) being used for driving the compressors (310 and 330) to work. By means of the apparatus, waste heat generated during a manufacturing process can be stored and reused, thus reducing the wastage of thermal energy, and saving energy.
