Low-temperature molten salt delivery pump 31, conveying valve 32 and fused salt electric heater 33；During heat accumulation, abandon wind abandon light electric energy or night it is cheap
Trough-electricity supply fused salt electric heater 33, fused salt is extracted out from low-temperature molten salt tank 1 by low-temperature molten salt delivery pump 31, process
It is changed into high-temperature molten salt after fused salt electric heater 33, flows into high temperature melting salt cellar 2.
The low-temperature molten salt tank 1 is also associated with low-temperature molten salt feeding pipe 4, and the low-temperature molten salt feeding pipe 4 is provided with
Low-temperature molten salt supply pump 41 and low temperature supply valve 42；
The high temperature melting salt cellar 2 is connected with high-temperature molten salt feeding pipe 5, and the high-temperature molten salt feeding pipe 5 is provided with height
Temperature molten salt pump 51 and high temperature supply valve 52；
The low-temperature molten salt feeding pipe 4 forms fused salt mixt supply pipe after being crossed with the high-temperature molten salt feeding pipe 5
Road 6, after the fused salt mixt feeding pipe 6 is communicated to heat exchanger 7, then the low-temperature molten salt tank is communicated to by return line 8
1；
During heat supply, high-temperature melting salt pump 51 and low-temperature molten salt supply pump 41 are respectively from high temperature melting salt cellar 2 and low-temperature molten salt tank 1
