Waste heat recycling power generation equipment taking perfluorohexanone as heat-conducting medium

Abstract

Waste heat recycling power generation equipment with perfluorohexanone as a heat-conducting medium comprises a waste heat boiler, a steam turbine generator unit and electric control equipment, a boiler barrel extending in the vertical direction and two evaporators stacked in the vertical direction are arranged in the waste heat boiler, and flow evaporation heating surfaces wound around the boiler barrel are arranged on the evaporators. The waste heat boiler is internally provided with descending pipelines wound on the corresponding steam device midstream evaporation heating surfaces, the bottoms of the descending pipelines are provided with main steam pipe bases, the descending pipelines are communicated with the steam turbine generator unit through the main steam pipe bases, and liquid perfluorohexanone circulates in the descending pipelines and is communicated with the steam turbine generator unit through the main steam pipe bases. In conclusion, the perfluoro-hexanone heat exchange device has the advantages that energy consumption is reduced, the heat exchange efficiency is high, the safety performance is good, the perfluoro-hexanone heat exchange device is environmentally friendly, leakage is not prone to occurring, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of waste heat utilization equipment, in particular to a waste heat recovery and utilization power generation equipment using perfluorohexanone as a heat conduction medium. Background technique [0002] Waste heat recovery and utilization technology is an important part of the power generation field. It mainly uses the waste heat flue gas of related enterprises (including but not limited to smelting, processing and production, and electricity), and the waste heat boiler collects the main steam into the generator set for power generation, so as to make full use of waste heat, Improve the efficiency of power generation and greatly reduce the cost of the enterprise; in the whole process of power generation of waste heat from flue gas, the characteristics of waste heat boiler and generator set directly determine the utilization rate and power generation efficiency of waste heat, and are the core equipment that aff...
