A solar thermal receiver

Abstract

The invention provides a solar heat collection receiver of a segmented structure. The solar heat collection receiver comprises a lower evaporation segment and an upper superheating segment, the evaporation segment and the superheating segment are connected through a steam drum, and the evaporation segment comprises an evaporation segment inlet header, an evaporating heating surface, an evaporation segment heating surface outlet tube, a descending tube, a circulating pump and heating surface inlet and outlet headers. A heat exchange medium enters the evaporation segment inlet header from the steam drum through the descending tube and the circulating pump, the heat transferring medium is uniformly distributed to the evaporation section heating surface through the headers to complete the process of energy exchange, the heat exchange medium is connected to the steam drum through the evaporation segment heating surface outlet tube, and the evaporating segment heating surface is a spiral water wall tube in structure and cylindrical in appearance.

Description

technical field [0001] The invention relates to a solar heat collection receiver, in particular to a tower type solar heat collection-steam receiver, which belongs to the technical field of solar energy applications. Background technique [0002] Solar thermal power generation is a power generation technology that realizes the utilization of clean energy through the conversion process of "light-heat-electricity". The conversion of heat is similar in principle to traditional fossil fuel power plants, only the source of energy is different. Solar thermal power generation converts clean low-energy-density sunlight into high-density energy through heliostats, and converts thermal energy into electrical energy in the form of a thermal cycle. According to the form of the receiver, solar thermal power generation technology can be divided into: trough type, tower type and butterfly type. Among them, the trough solar thermal power generation technology has been commercialized, and ...
