Superhigh-temperature waste heat steam production system

Abstract

The invention provides an ultra-high-temperature waste heat steam production system which comprises a multi-flow heat regenerator comprising a plurality of heat regeneration pipelines exchanging heat with one another; the compressor unit comprises multiple stages of compression sections which are sequentially connected, and an inlet of each stage of compression section is connected with an outlet of one heat return pipeline; the steam generator comprises a steam production pipeline and a heat exchange pipeline which exchange heat with each other, and the heat exchange pipeline is connected with the last-stage compression section and the last heat return pipeline; the multi-stream heat exchanger comprises a heat source pipeline and a plurality of heat exchange sections which exchange heat with each other, and each heat exchange section is connected with a heat return pipeline; the liquid separation tanks are sequentially connected, the first liquid separation tank is connected with the last heat return pipeline, a gas outlet of each liquid separation tank is connected with an inlet of one heat return pipeline, and a liquid outlet of the last liquid separation tank is connected with inlets of the heat exchange sections. The ultrahigh-temperature waste heat steam production system can produce steam of a specific pressure grade, steam production cost and energy consumption are low, a steam compressor does not need to be used, the system process is simple, and waste heat utilization is reasonable.
