HEAT-STORAGE MEDIUM CONVEYING SYSTEM FOR SOLAR-THERMAL POWER PLANT

Title:

HEAT-STORAGE MEDIUM CONVEYING SYSTEM FOR SOLAR-THERMAL POWER PLANT

Document Type and Number:

WIPO Patent Application WO/2021/057700

Kind Code:

A1

Abstract:

The present invention provides a heat-storage medium conveying system for a solar-thermal power plant, comprising a high-level tank subsystem which comprises a high-level tank used for storing a heat-storage medium, and further comprising a heat-storage medium conveying subsystem. The high-level tank subsystem is connected to the heat-storage medium conveying subsystem. The heat-storage medium conveying subsystem comprises a low-level tank. The installation height of the low-level tank is lower than that of the high-level tank, and the volume of the low-level tank is less than that of the high-level tank. The heat-storage medium partially or fully enters the low-level tank from the high-level tank according to own gravity. The low-level tank is provided with a transfer pump. The heat-storage medium is pumped out of the low-level tank by means of the transfer pump. The present invention solves the problems of cost, operational and maintenance cost caused by a vertical long-axis submerged molten salt pump, avoiding the safety hazards of large and small tanks or high and low tank designs.
