The embodiment of the invention provides a liquid air energy storage power generation system. The liquid air energy storage power generation system comprises a liquid air energy storage unit and a molecular sieve adsorption tower automatic regeneration unit. The liquid air energy storage unit comprises a first molecular sieve adsorption tower and a second molecular sieve adsorption tower. The first molecular sieve adsorption tower and the second molecular sieve adsorption tower are connected in parallel. The first molecular sieve adsorption tower and the second molecular sieve adsorption tower can independently and alternately perform decarburization and dehydration. The molecular sieve adsorption tower automatic regeneration unit is connected with the liquid air energy storage unit so that the first molecular sieve adsorption tower and the second molecular sieve adsorption tower can utilize heat generated in the liquid air energy storage process to independently and alternately perform the automatic regeneration process. Therefore, the system can fully utilize cold and heat energy in the liquid air energy storage process to complete adsorption and regeneration of the molecular sieve adsorption towers, auxiliary cold and heat self supply of the liquid air energy storage power generation system can be achieved, the self consistency of the system is improved, and the economical efficiency and the energy utilization rate of the system are improved.
Description
technical field [0001] The invention relates to the technical field of liquid air energy storage, in particular to a liquid air energy storage power generation system. Background technique [0002] In the liquid air energy storage system, before the air enters the cold box for liquefaction, it needs to use the molecular sieve purification system to remove the water vapor, carbon dioxide and acetylene contained in it. The traditional molecular sieve purification system needs to configure a refrigeration unit before the air intake to pre-cool the air entering the molecular sieve purification system and increase the adsorption capacity of the molecular sieve. At the same time, when the molecular sieve is regenerated, an additional electric heater is required to heat the regenerated gas and take away as much impurity gas as possible. In the process of adsorption and regeneration, additional equipment and energy consumption are required, and the operating efficiency of the syste...
