Salt melting system based on natural gas heat-conducting oil furnace and used for solar photo-thermal power station

The invention discloses a salt melting system based on a natural gas heat-conducting oil furnace and used for a solar photo-thermal power station, and belongs to the technical field of photo-thermal salt melting production. The invention aims to shorten the salt melting period and reduce the salt melting cost. The salt melting system based on the natural gas heat-conducting oil furnace and used for the solar photo-thermal power station comprises a salt melting furnace, a heat exchanger and a fused salt storage tank, wherein the salt melting furnace communicates with a low-temperature fused salt inlet of the heat exchanger through a fused salt pipeline and communicates with the fused salt storage tank through a conveying pump, a high-temperature fused salt outlet of the heat exchanger communicates with the salt melting furnace, and a connection relationship is established between the heat exchanger and the natural gas heat-conducting oil furnace; and the natural gas heat-conducting oil furnace is used for prov
