Specific implementation mode
Preheating below by the fused salt storage tank of the specific embodiment narration present invention and salt dissolving system.Except non-specifically saying
Bright, technological means is method known in those skilled in the art used in the present invention.In addition, embodiment is interpreted as
Range that is illustrative, being not intended to limit the present invention, the spirit and scope of the invention are limited only by the claims that follow.For ability
For field technique personnel, under the premise of without departing substantially from spirit and scope of the present invention, various changes that technical solution of the present invention is made
Shape and improvement, also belong to protection scope of the present invention.
As shown in Figure 1 and Figure 2, the preheating of fused salt storage tank of the invention and salt dissolving system, including storage tank 1, storage tank 2, molten salt furnace
3, exhaust gas processing device 6 and preheating furnace 5, the molten salt furnace 3, exhaust gas processing device 6, storage tank 1 and preheating furnace 5 are sequentially connected, institute
State connection natural gas（Or propine）The exhaust gas passes 19 of tail gas are connected to molten salt furnace 3 after burning, and the connection of gaseous fuel device 301 is molten
Salt stove 3, electric heater 101 connect storage tank 1, gas flow control are additionally provided between exhaust gas processing device 6 and preheating furnace 5
Valve 10.Between the gas outlet passage 13 and molten salt furnace 3 of storage tank 1, it is additionally provided with multiple-way valve 9 and multiple-way valve 7.
When being preheated to storage tank 1, first by natural gas（Or propine）Tail gas after burning is imported molten by exhaust gas passes 19
In salt stove 3, the tail gas is passed through exhaust gas processing device 6 later and is handled, finally imports again in storage tank 1 and it is preheated.
While the tail gas, which enters storage tank 1, to be preheated, air in storage tank 1 can be discharged into pipeline by the chimney 501 on preheating furnace 5
Air.
In addition, when being preheated to storage tank 1, the natural gas of temperature reduction after being preheated to storage tank 1（Or propine）After burning
Gas is finally passed through by gas outlet passage 13, multiple-way valve 9, multiple-way valve 7 in molten salt furnace 3, with just enter the temperature of molten salt furnace 3 compared with
High natural gas（Or propine）Mixed gas is re-fed into storage tank 1 and is preheated to storage tank 1 by the gas mixing after burning, because
Just enter the natural gas of molten salt furnace 3 in most cases（Or propine）Gas temperature is higher than the temperature of 1 preheating requirement of storage tank after burning, therefore
Natural gas can adequately be utilized using this method as far as possible（Or propine）The heat of gas after burning, to reduce as far as possible
Energy consumption.
Wherein, the gas flow control valve 10 being set between exhaust gas processing device 6 and molten salt furnace 3, can be according to tail gas
The size of temperature regulated flow prevents temperature in storage tank 1 from can rise too fast or rising too high because of the improper of flow.
Traditional fused salt salt dissolving process generally first can melt fused salt using electrically heated mode, reuse air heat spoke later
Penetrate heating fused salt, in turn with heating fused salt further go fusing salt dissolving stove in fused salt, used in heat radiation heating
The gas of fused salt can generally be discarded, and the waste of mass energy is caused.The fused salt storage tank preheating of the utility model and salt dissolving system,
The gas for the heat radiation heating fused salt discarded using tradition further heats storage tank, makees to play the preheating to entire storage tank
With.Efficiently using for its tail gas after being heated to fused salt, is utilized the energy to the greatest extent.In addition, the system structure is simply tight
It gathers, space is small, not only reduces system operation expense, also saves the run time of whole system.
Wherein, further include the salt dissolving stove 4 for connecting storage tank 1, electric heater 401, the salt dissolving stove are set on the salt dissolving stove 4
4, molten salt furnace 3, preheating furnace 5 are sequentially connected,
As the temperature in storage tank 1 constantly increases, the gas temperature come out from storage tank 1 also can constantly rise, when the gas
When temperature is higher than the temperature of fused salt in salt dissolving stove 4, the gas come out from storage tank 1 is imported into preheating furnace 5, is used as at the preheating of fused salt
Reason.
Before storage tank 1 enters salt, need first to dissolve and heat to having been charged into the fused salt in the salt dissolving stove 4 of solid-state fused salt, i.e., first
Salt dissolving stove 4 is heated by electric heater 401, later, the fused salt in salt dissolving stove 4 starts to melt, when the solid-state in salt dissolving stove 4 is molten
After the liquid level of formed liquid fused salt reaches normal work liquid level after salt melts, start to the liquid fused salt cycle in salt dissolving stove 4
Heating, i.e., so that the liquid fused salt come out from salt dissolving stove 4 pass sequentially through preheating furnace 5 and molten salt furnace 3 heated after return to salt dissolving again
Stove 4, the liquid level of fused salt continues to increase in salt dissolving stove 4 later, and the cycle by preheating furnace 5 and molten salt furnace 3 so again repeatedly adds
Heat waits for that gas temperature atmosphere reaches fused salt normal working temperature in storage tank 1, and it is to start salt dissolving that Temperature Distribution is uniformly rear enough
The liquid fused salt that desired temperature has been heated in stove 4 is sent directly into operation in storage tank 1.
The fused salt storage tank preheating of the present invention and salt dissolving system, are also connected between fused salt storage tank 1 and storage tank 2 and are provided with multiple-way valve
8 and multiple-way valve 9, it is additionally provided with multiple-way valve 7 between multiple-way valve 9, molten salt furnace 3 and preheating furnace 5.
Multiple-way valve 9 is separately connected the gas outlet passage 13 of storage tank 1 and the gas outlet passage 14 of storage tank 2, and multiple-way valve 8 divides
It Lian Jie not the gas inlet passage 11 of storage tank 1 and the gas inlet passage 12 of storage tank 2.
When storage tank 2 need to preheat, multiple-way valve 8 is switched to the gas access of storage tank 2 from the gas inlet passage 11 of storage tank 1
Multiple-way valve 9 is switched to the gas outlet passage 14 of storage tank 2 by access 12 from the gas outlet passage 13 of storage tank 1, later operation system
System, natural gas（Or propine）Tail gas after burning starts to carry out warm operation to storage tank 2.In warm, when in storage tank 2
Moment pressure it is excessive when, open gas control valve 15, superfluous tail gas be discharged by exhaust gas passes 19.
