A multi-stage plate-type evaporation absorption cooling device includes components such as a coolant water evaporator (21), a low pressure absorber (22), a four-way solution heat exchanger (10), a steam mixing tank (1), a first plate-type inner coupling phase-change heat exchanger (2), a second plate-type inner coupling phase-change heat exchanger (4), a third plate-type inner coupling phase-change heat exchanger (6), a first flash separating tank (3), a second flash separating tank (5), a third flash separating tank (7), a mechanical steam compression pump (11) and a condensation water liquid level meter (20). Dilute solution is continuously evaporated and concentrated by a plate-type evaporation unit formed of three plate-type inner coupling phase-change heat exchangers (2, 4, 6), and the condensation latent heat of the coolant water steam produced in the dilute solution evaporation process is fully recovered and used to generate regenerated steam, which is recompressed by the mechanical steam compression pump (11) to increase the pressure and temperature and used as a heat source. |
