Document Type and Number:
WIPO Patent Application WO/2022/198922
Kind Code:
A1
Abstract:
A power plant multi-stage waste heat comprehensive utilizing apparatus and method. The apparatus comprises a condensed water pipeline, a condenser (1), an absorption heat pump absorber (6), an absorption heat pump condenser (4), a unit low-pressure heater water side pipeline, a lubricating oil supply pipeline, a lubricating oil supply three-way valve (12), a lubricating oil cooler (8), an absorption heat pump evaporator (5), a deaerator (2), a deaerator steam exhaust three-way valve (14), a deaerator emptying pipeline, an absorption heat pump generator (3), an expansion valve (16), and a solution heat exchanger (7). By means of the apparatus and the method, the steam exhaust of the deaerator (2) and the recycling of waste heat of return oil of lubricating oil are realized, the temperature of condensed water is increased, and the problem of white smoke plume of exhaust steam of the deaerator (2) is solved.
