Technical field
The invention belongs to the tower photo-thermal power generation technical fields of high temperature solar fused salt, and in particular to a kind of tower photo-thermal of fused salt
The cold salt pumping system of power station steam-operating.
Background technology
With the gradual shortage of fossil fuel, it is also increasing that renewable energy power generation occupies ratio in the market, and the sun
Energy resource is that reserves are maximum in all regenerative resources, and the installed capacity of solar power generation increases year by year.
The installed capacity in large size fused salt tower photo-thermal power station at present is 100MW, the cold salt pump allocation plan used for 4 ×
33% or 3 × 50% scheme.The cold salt pump motor of separate unit of this scheme is used as 6kV high-voltage motors, power in 3 ~ 4MW or so, this
Sample station service in unit operation can reach close to 10MW, and station service is very high.
Cold salt pump is by sloppy heat salt（About 290 DEG C）The heat dump of heat absorption top of tower is squeezed into, is arrived by mirror field reflected sunlight
On heat dump, sloppy heat salt is heated to be hot melt salt（About 565 DEG C）.If the cold unexpected power down of salt pump motor, heat dump do not have suddenly
Fused salt flows, and can burn heat dump.So also there is certain safe and reliable risk using motor driving.It uses at present
Scheme be that sloppy heat salt enters and an inlet container placed before heat dump, and when being filled with sloppy heat salt, pass through tower on heat absorption tower
Under High Pressure Air Compressor to inlet container be pressurized.Sloppy heat salt has 50% liquid level in inlet container.When cold salt pump motor is dashed forward
During right power down, the rapid cut-off butterfly valves of the cold salt pump discharge of quick closedown prevent fused salt from flowing back to cold salt pump, under the driving of compressed air
Sloppy heat salt in inlet container is squeezed into heat dump and keeps the flow rate of molten salt of one minute, Jing Chang passes through within the time of one minute
Protection power source（UPS or diesel-driven generator）Heat dump is withdrawn, avoids burning heat dump.
