Method and System for High-Efficiency Heat Energy Recycling Applicable to Plateau Areas Using a High-Temperature Concentrated Solar Thermal Collector

摘要

The invention discloses a high efficiency thermal energy recovery method and system, and a high temperature concentrated solar thermal collector. A concentrated solar photo-thermal device is used to heat heat-transfer oil to a high temperature and the oil is used for rapid heat replenishment for decompressing evaporation. Multiple methods are also used to recover thermal energy so as to recover a large part of thermal energy in a production process, thereby enabling the continuous production in plateau areas, reducing the electricity consumption, lowering the capacity of photovoltaic power stations, and reducing the fixed investment.
