Abstract

The invention belongs to the field of the salt melting equipment and aims to provide a solar-heating assisted salt melting system which consumes less fuel and less affects the environment. The solar-heating assisted salt melting system comprises a salt melting furnace and a heating device, wherein the salt melting furnace is provided with a low-temperature salt storage tank with a salt melting pump; the solar-heating assisted salt melting system further comprises a solar heat absorbing device, two heating pipes and a high-temperature salt storage tank with a salt melting pump; the outlet of the salt melting pump of the low-temperature salt storage tank is communicated with the inlet of the solar heat absorbing device through a first heating pipe; the outlet of the solar heat absorbing device is communicated with the high-temperature salt storage tank through a second heating pipe; the outlet and the inlet of the heating device are communicated with the inlet of the low-temperature salt storage tank and the outlet of the salt melting pump of the high-temperature salt storage tank respectively; and the solar-heating assisted salt melting system is provided with a preheating device used for preheating the heating pipes. The solar-heating assisted salt melting system consumes less fuel and less affects the environment.

Description

technical field [0001] The invention relates to the field of molten salt equipment, in particular to a solar-assisted heating molten salt system with less fuel consumption and less impact on the environment. Background technique [0002] Molten salt has a high heat capacity and a wide range of liquid-phase operating temperatures. It is a heat-carrying medium with good performance and can provide high temperature; Thermal device composition; the invention of Chinese patent announcement number CN101625155A discloses a generator coal gas molten salt furnace, which uses CO and H2 mixed gas produced by a water gas generator as fuel, and burns and heats the molten salt on the inner wall of the molten salt furnace in the furnace of the molten salt furnace. The salt heating coil, after the heated molten salt flows out of the molten salt furnace, it undergoes sufficient heat exchange with the heating device, and after releasing heat, it can flow back to the molten salt furnace for ci...
