Distributed energy source system utilizing waste heat deeply

A distributed energy source system for improving waste heat utilization efficiency, comprising:

• a primary waste heat recycling module, comprising an absorption type cold/hot water unit, wherein the absorption type cold/hot water unit absorbs heat in a medium-high temperature flue gas and generates both a heated water and a cooled water, wherein the medium-high temperature flue gas has a temperature higher than 120° C.;
• a membrane distillation type seawater desalination module, comprising:
• a hot seawater storage mechanism for introducing the medium-high temperature flue gas, wherein the hot seawater storage mechanism is internally provided with a liquid pump, and the hot seawater storage mechanism stores a hot seawater having a temperature of 65° C.;
• a hydrophobic membrane distillation assembly, wherein the hydrophobic membrane distillation assembly is communicated with the liquid pump;
• a condensation mechanism for introducing seawater as condensate water;
• and
• a first dividing wall type heat exchanger, wherein the hydrophobic membrane distillation assembly, the condensation mechanism, the first dividing wall type heat exchanger and the hot seawater storage mechanism are communicated in sequence;
• and
• a membrane type thermoosmosis power generation module, comprising:
• a heat storage mechanism connected with both a heated water output end of the absorption type cold/hot water unit and a flue gas output end of the hot seawater storage mechanism;
• and
• a heating mechanism arranged in the heat storage mechanism for heating, wherein a first end of the heating mechanism, a membrane contactor, a third dividing wall type heat exchanger and a second end of the heating mechanism are communicated in sequence to realize circulation of a heated fluid, wherein a first end of the membrane contactor, the third dividing wall type heat exchanger, a second dividing wall type heat exchanger and the membrane contactor are communicated in sequence to realize circulation of a cooled fluid;
• wherein a cooled water output end of the absorption type cold/hot water unit is communicated with the second dividing wall type heat exchanger, and a cooled water runner output end of the membrane contactor is communicated with a power generation mechanism and the heating mechanism in sequence to push the power generation mechanism to generate electricity.
