Three-phase absorption type heat storage system

The invention relates to a three-phase absorption type heat storage system which comprises a solution reactor and a refrigerant reactor. The solution reactor comprises a solution tank, a solution spraying disc, a solution falling film heat exchanger, a solution filter cartridge, a solution pump and a solution circulating pipeline, the bottom end of the solution filter cartridge is communicated with an inlet of the solution pump, and an outlet of the solution pump is communicated with the solution spraying disc through the solution circulating pipeline to form solution circulation; a filter screen for the solution to pass through is arranged at the middle upper part of the solution filter cartridge to realize high-position liquid feeding; the refrigerant reactor comprises a refrigerant tank, a refrigerant water spraying disc, a refrigerant falling film heat exchanger, a refrigerant pump and a refrigerant circulating pipeline, the bottom end of the refrigerant tank is communicated with an inlet of the refrigera
