The one outlet for stating low-temperature molten salt tank is entered after the heating of fused salt electric heater 3 in high-temperature molten salt tank 4 by low-temperature molten salt pump 2；
The fused salt entrance of the outlet connection evaporator 12 of the static mixer 7, the fused salt outlet connection low-temperature molten salt tank of evaporator 12
1, three branches are drawn in the hot working fluid outlet of evaporator, and first branch is directly connected to heat user 13, according to heat user heat
Mode judges whether there is condensing hot air furnace, and if any condensing hot air furnace, then condensed water is pumped by feed pump 8 in oxygen-eliminating device 9, is carried out down
One cycle；
Article 2 branch connects a side-entrance of preheater 11, and a side outlet of preheater 11 connects oxygen-eliminating device 9, deoxygenation
The outlet of device 9 connects another side-entrance of preheater 11 by water circulating pump 10；Hot working fluid in evaporator out is as heat source
The condensed water from oxygen-eliminating device 9 is heated to 180 DEG C, oxygen-eliminating device 9 is then returned to after steam cooling；
Article 3 branch is directly connected to oxygen-eliminating device 9, and the hot working fluid come out in evaporator removes water supply as heat source and is pumped into
Water supply (condensed water) in oxygen, and the water supply (condensed water) in oxygen-eliminating device 9 is heated to 104 DEG C；
Another side outlet of the preheater connects the hot working fluid import of the evaporator.
Heretofore described heat user is not limited only to industrial steam user, can also be the heat source of secondary heating net,
And its temperature can be adjusted according to user demand.
The course of work of molten salt energy-storage heating system of the present invention with fused salt static mixer be：
The night dip electricity period, (operating temperature of low-temperature molten salt is set as the low-temperature molten salt being placed in low-temperature molten salt tank 1
190 DEG C) heating is pumped into fused salt electric heater 3 by low-temperature molten salt pump 2 becomes high-temperature molten salt (operating temperature of high-temperature molten salt is set
It is set to 405 DEG C), and be stored in high temperature melting salt cellar 4, complete fused salt heat-accumulating process；
When end heat user 13 needs heat, high-temperature melting salt pump 5, mixed salt pump for liquid salts 6 are respectively by high-temperature molten salt and low temperature
Fused salt is pumped into static mixer 7 mixes simultaneously, work temperature of the mixed temperature of molten salt between high-temperature molten salt and low-temperature molten salt
(for 300 DEG C) between degree, after evaporator 12, temperature of molten salt returns after being reduced to 190 DEG C in low-temperature molten salt tank 1.
The present embodiment heat user is only by taking 185 DEG C of saturated vapor as an example.It is flowed through through feed pump 8 with the system water supply of hot side
Enter evaporator 12 after oxygen-eliminating device 9, water circulating pump 10, preheater 11, is changed with 300 DEG C of fused salt mixts from static mixer 7
Heat, (185 DEG C of saturated vapor is come out from evaporator 12 to the saturated vapor of 185 DEG C of generation after heat exchange, and whole flow process is：104
DEG C water supply through water circulating pump 10 enter preheater 11,180 DEG C are heated at preheater 11, later 180 DEG C of saturated water
Into evaporator 12, become 185 DEG C of saturated vapor through the heating of evaporator 12.), it is detached through evaporator 12, hot steam point three
Branch flows out, and first branch steam is routed directly to heat user, which can be industrial steam user, according to heat user
Judge whether there is condensing hot air furnace with hot mode, if any condensing hot air furnace, then condensed water is pumped into system by feed pump 8, carries out down
One cycle；Article 2 branch steam enters preheater 11, heats the condensed water from oxygen-eliminating device 9 to 180 DEG C as heat source, steam
Oxygen-eliminating device 9 is then returned to after cooling；Article 3 branch steam is directly entered oxygen-eliminating device 9, is removed in water supply (condensed water) as heat source
Oxygen, and the water supply (condensed water) in oxygen-eliminating device 9 is heated to 104 DEG C.The purpose for adding oxygen-eliminating device be in order to system to
The steam condensate (SC) deoxygenation and heating of water, preheater 11, because easily generating corrosion to equipment if oxygen is more in water；By oxygen-eliminating device
Operating pressure limits, and oxygen-eliminating device outlet temperature is generally 104 DEG C, to prevent from causing to melt into the feed temperature of evaporator 12 is too low
Salt frozen block need to be pumped into preheater 11 through water circulating pump 10 in evaporator, from the system water supply of oxygen-eliminating device out and be again heated to
180 DEG C, into evaporator heat exchange, the purpose for adding preheater here is mainly heating system water supply, promotes feed temperature, because
Fused salt has solidification point, and if feed temperature is too low, fused salt is just easy to be set in evaporator, causes system frozen block, institute
To have to promote feed temperature, feed temperature is made to be on fused salt solidification point, ensure that fused salt does not solidify, ensures system safety
Operation.
Molten salt energy-storage heating system of the present invention with fused salt static mixer can effectively improve the temperature in use of fused salt,
On the basis of identical amount of stored heat Q, such as in the energy storage heating system of not static mixer, the temperature of energy storage high-temperature molten salt is
300 DEG C, the low-temperature molten salt temperature after heat exchange is 190 DEG C, and the energy storage temperature difference is 110 DEG C, according to heat balance formula
Q=cm Δs t
Under conditions of not considering fused salt allowance and heat exchange efficiency, calculating energy storage molten salt dosage is Q/ (c*110).It adds quiet
After state mixer, the temperature in use of energy storage high-temperature molten salt is up to 405 DEG C, and the low-temperature molten salt temperature after heat exchange is 190 DEG C, energy storage temperature
Difference is 215 DEG C, and can be calculated energy storage molten salt dosage according to heat balance formula is Q/ (c*215), and dosage is not added only quiet
The 51.2% of state mixer fused salt dosage.It can be seen that the molten salt energy-storage heating system for adding static mixer significantly reduces
The usage amount of fused salt reduces energy storage device volume, saves system footprint area, and the flow of pump for liquid salts accordingly reduces, and significantly reduces
Pump power consumption.
The energy storage molten salt used in the above process is low melting point fused salt, and fusing point is 115 DEG C, to ensure it in heat transfer process
In do not solidify, the low-temperature molten salt temperature after evaporator heat exchange is set as 190 DEG C, the upper limit temperature in use of this low melting point energy storage molten salt
Take higher than 405 DEG C, but to reduce storage tank manufacture material, it is 405 DEG C that the temperature of heat accumulation high-temperature molten salt is taken in this system.
The temperature in use of energy storage high-temperature molten salt can also further increase in the present invention, can be to high temperature when temperature improves again
The material of fused salt tank requires stringenter, high temperature melting salt cellar made of the application selection carbon steel, the use of storage high-temperature molten salt
Temperature upper limit is 405 DEG C, if laying particular emphasis on the dosage for reducing high-temperature molten salt or increasing its energy storage capacity, can select other resistance to height
High temperature melting salt cellar made of warm material, fused salt dosage is less, equipment volume smaller.
Molten salt energy-storage heating system of the present invention with fused salt static mixer only need to add in system structure one it is mixed
The process that high temperature energy-storage can be realized in salt pump and corresponding fused salt pipeline, valve, low temperature mixed salt exchanges heat, whole system structure letter
It is single, easy to operate, control it is simple, at low cost, be very suitable for commercial introduction application.
The present invention does not address place and is suitable for the prior art.
