Abstract

The invention relates to a technology and device for efficient melt and condensation prevention of a solar photo-thermal power generation phase-change energy-storage medium. When the solar photo-thermal power generation phase-change energy-storage medium is melted for the first time, high-temperature heat energy produced by a heating system at the bottom of a tank is directly transmitted to the solar photo-thermal power generation phase-change energy-storage medium in the tank to melt the solar photo-thermal power generation phase-change energy-storage medium in a heat-storage tank body, and when temperature layering, condensation and solidification of the solar photo-thermal power generation phase-change energy-storage medium happen, the temperature of heat-storage phase-change materials of the heat-storage tank body can be even through convection or mechanical flow mixing, and the problems of temperature layering, condensation and solidification of phase-change energy-storage materials in the heat-storage tank body can be solved. The technology and device for efficient melt and condensation prevention of the solar photo-thermal power generation phase-change energy-storage medium is clean, simple, efficient and easy to maintain, and the purposes of melt and condensation prevention of the solar photo-thermal power generation phase-change energy-storage medium are achieved.

Description

technical field [0001] The invention relates to the technical field of solar photothermal power generation energy storage, in particular to a technology and device for efficient melting and anti-condensation of a phase change energy storage medium for solar photothermal power generation. Background technique [0002] The solar thermal power generation energy storage system must have a heat storage medium for high temperature heat transfer. The heat storage medium is generally molten salt or other phase change materials. These heat storage media need to be melted before use. run in the system; [0003] For the high-temperature heat storage medium used in the solar thermal power generation energy storage system, due to special reasons, the temperature difference between the liquid surface of the heat storage medium in the heat storage tank and the bottom increases, and temperature stratification is prone to occur, and the bottom temperature decreases and condensation and solid...
