Solution composite regeneration system of heat source tower

The invention provides a heat source tower solution composite regeneration system which comprises a regeneration tower, a solution tank, a driving heat source and a plurality of pipelines built among the regeneration tower, the solution tank and the driving heat source, and the pipelines comprise an exhaust pipeline and a first liquid inlet pipeline which are connected to the solution tank; the low-pressure boiling pipeline is connected with the solution tank, the driving heat source, the first heat exchanger, the second heat exchanger and the solution tank; the second liquid inlet pipeline is connected with the spraying head; and the liquid outlet pipeline is connected with the solution tank and the solution tank. The composite regeneration system comprises the two regeneration systems, has the low-pressure boiling regeneration function and the hot air regeneration function at the same time, can drive the two regeneration systems to work cooperatively only by arranging one driving heat source, and has high r
