A kind of intelligent Molten salt heating system is disclosed in the Chinese invention patent of No. 201610543919.4, the temperature of fused salt can be relied on to enter
Row intelligent control, fused salt meet that temperature conditionss could be stored in salt holding vessel, structurally simple, economical intelligence after multiple circulating-heating
Can, fused salt salt dissolving and heating effect during system operation are good.But the improvement of two kinds of high-temperature molten salt pump installations in above-mentioned patent
All it is not involved with the guard method to fused-salt medium attribute in fused salt tank.
For above-mentioned defect, the present inventor has invented a kind of high-temperature melting salt pump molten protection device, in fused salt tank
On through fused salt tank cover plate add nitrogen cylinder, be passed through the fused salt that low-pressure nitrogen comes in protective pot, prevent fused salt from going bad；And in fused salt cover
Opening is eated dishes without rice or wine on plate, and steam caused by air and fused salt, avoids air pressure in tank too high, the operating of pump is influenceed, one in drain tank
Determine the loss of reduction fused salt in degree, improve the stable operation of pump for liquid salts.
The content of the invention
In order to solve the above problems, the invention provides a kind of high-temperature melting salt pump molten protection device.The fused salt of the device
Protection is realized by following manner：Nitrogen cylinder provides nitrogen, and nitrogen moves to fused salt tank after pressure-reducing valve depressurizes, through metal hose
In, fused salt is protected；Steam caused by air and fused salt, avoids gas in tank in drain drain tank on fused salt tank cover plate
Press through height.The environment of one safety and stability is provided for fused salt pump operation.
Technical scheme is used by realizing above-mentioned purpose：
1st, the high-temperature melting salt pump molten protection device is mainly by fused salt tank (1), pump for liquid salts (2), motor (3), nitrogen cylinder
(4), pressure-reducing valve (5), fused salt tank cover plate (6), vapor detector (7), pump for liquid salts fixed plate (8), nitrogen inlet (9), drain
(10) and the part composition of pump shaft (11) etc. ten, it is mainly characterized by：Pressure-reducing valve (5) is opened, the nitrogen in nitrogen cylinder (4) is through subtracting
After pressure valve (5) decompression, the nitrogen inlet (9) on fused salt tank cover plate (6) is moved to by metal hose and entered in fused salt tank (1),
Prevent air and fused salt from reacting, and then fused-salt medium is protected.
2nd, the drain (10) in the fused salt pump closure (6) of the high-temperature melting salt pump molten protection device is used for empty in drain tank
Steam caused by gas and fused salt, avoid the air pressure in fused salt tank too high, influence the normal operation of pump；Drain (10) steam-out (SO)
Detector (7), detect the content of the steam through drain (10) discharge and into gradation parameter；Detector (7) can connection server,
Medium for gathering and analyzing vapor detector (7) monitoring is used to analyze.
3rd, in said apparatus, vapor detector (7) can also connect single-chip microcomputer, single-chip microcomputer connection buzzer and/or flash of light
Lamp, when the steam content that vapor detector (7) monitors exceeds preset value, buzzer and/or flash lamp send signal and make it
Sound or color variations alarm are produced, so as to which staff can adjust running status according to signal.
According to above-mentioned steps, a kind of high-temperature melting salt pump molten protection device can be obtained.
High-temperature melting salt pump molten protection device is determined by the above method, mainly by fused salt tank (1), pump for liquid salts (2), motor
(3), nitrogen cylinder (4), pressure-reducing valve (5), fused salt tank cover plate (6), vapor detector (7), pump for liquid salts fixed plate (8), nitrogen inlet
