An Intelligent Molten Salt Heating System

Abstract

The invention relates to an intelligent molten salt heating system. The intelligent molten salt heating system comprises a molten salt tank, a heater, a first three-way valve, a molten salt heating furnace, a second three-way valve, a molten salt pump and a molten salt storage tank; the heater is started; when the temperature of molten salt flowing through the first three-way valve and the second three-way valve by the molten salt pump is lower than the temperature of the molten salt entering the molten salt storage tank, the molten salt is fed in the molten salt heating furnace through the first three-way valve; and when the temperature of the molten salt flowing through the first three-way valve and the second three-way valve by the molten salt pump is not lower than the temperature of the molten salt entering the molten salt storage tank, the molten salt is fed in the molten salt storage tank through the second three-way valve. Visibly, the intelligent molten salt heating system intelligently controls opening of the first three-way valve and the second three-way valve by dint of the temperature of the molten salt; the molten salt only can be stored in the molten salt storage tank after satisfying the temperature conditions through multiple times of circular heating; and the intelligent molten salt heating system is simple in structure, economical, intelligent and excellent in heating effect in salt melting and system operation.

Description

technical field [0001] The invention relates to the technical field of photothermal power generation, in particular to an intelligent molten salt heating system. Background technique [0002] Solar power generation technology is affected by various factors such as light, climate, season, and region, which will greatly restrict the continuity and stability of solar energy utilization. Solving the continuous availability of solar power is the key to realize the large-scale application of solar power, improve efficiency and reduce costs. The heat storage system of solar power generation can store the heat energy when there is sufficient sunlight, and release it to generate steam power generation when the sunlight radiation is insufficient or there is no light at night. When the power demand is insufficient, the thermal energy is stored, and the stored thermal energy is used to generate electricity to meet the demand when the power demand peaks, which can realize the role of "s...

AI Technical Summary

Problems solved by technology

At present, binary solar salt molten salt and ternary Hitec molten salt are mostly used in photothermal power stations. Due to the high melting point of molten salt, it is necessary to heat the molten salt before use. The main methods include steam heating, electric heating, etc. At the same time, in the process of operation, it is necessary to use electric tracing heating for the molten salt storage tank. This device has problems such as complex structure, high cost, and difficult maintenance.
