Abstract

The invention belongs to the technical field of heat storage molten salt, and particularly relates to a liquid molten salt high-temperature precipitate separation system. According to the liquid molten salt high-temperature precipitate separation system, molten salt in a molten salt tank is divided into multiple paths after being pumped by a salt pumping main pipe; wherein a plurality of paths are directly discharged back to the bottom in the molten salt tank through a disturbance pipe for disturbing precipitates at the bottom of the tank; wherein one path is discharged back into the molten salt tank after precipitates are filtered by the on-line automatic filtering device. Fused salt high-temperature precipitates can be filtered, adverse effects of the precipitates on equipment are avoided, the use performance of a power station is improved, and the service life of the power station is prolonged. The device is small in occupied area and can be directly placed on the top of the tank body; and precipitates at the bottom of the tank are disturbed by the disturbance pipe without additionally arranging a stirring device, so that the cost is saved.
