As shown in Figures 2 and 3, an exemplary embodiment of the present invention, the fused salt heat dump with filter device into
Mouth surge tank includes surge tank ontology 1 and the fused salt import tube assembly 3 being arranged on surge tank ontology 1, fused salt outlet group
Part 4 and fused salt bypass tube assembly 5.Specifically, import surge tank is molten by fused salt entrance tube assembly 3 and fused salt tedge and low temperature
Salt storage tank is connected, and exports tube assembly 4 by fused salt and is connected with fused salt heat dump, by fused salt bypass tube assembly 5 and down-comer and
Salt storage tank is connected.
Wherein, the surge tank ontology 1 of import surge tank is fixed by skirt 2 and there are maintenance manholes on skirt 2, with convenient
Buffer the construction and maintenance of pot bottom.In addition, the import surge tank operating temperature due to fused salt heat dump is higher, in surge tank sheet
The outer wall of body is equipped with certain thickness outer heat insulation layer, and according to fused salt working characteristics, heat tracing group is arranged in outer heat insulation layer
Part.
According to the process of heat absorber system, fused-salt medium enters in tank through the fused salt import tube assembly 3 of import surge tank.Root
According to the present invention, fused salt import tube assembly 3 includes tube socket 301, inward nozzle 302 and vertical filter unit 303,301 basis of tube socket
Setting demand is fixed on surge tank ontology 1, the both ends of inward nozzle 302 respectively with 303 phase of tube socket 301 and vertical filter unit
Even, tube socket 301 can be connect by welding manner with outer tube.
Wherein, it is provided with fused salt filtering dispensing orifice on the side wall of vertical filter unit 303 and bottom is closed end.Thus, it is possible to
So that the fused-salt medium into import fused salt tank is carried out the integrated treatment of flow distribution and filtering in entrance, distributes fused salt stream
The solid particle carried in working medium and impurity are effectively intercepted while dynamic without increasing the ancillary equipments such as any heat tracing, heat preservation.
As shown in figure 3, vertical filter unit 303 is preferably to filter along the fused salt that the short transverse of import surge tank extends
Bucket, the fused salt filter vat include reamer section 3031, staving 3032 and closed end 3033, and fused salt filtering dispensing orifice 3034 is uniformly distributed
On the side wall of staving 3032, the volume and side-wall hole quantity and layout density that fused salt filtering is led to need to consider abundant in the scarfing cinder period
Amount.The impurity or solid particle being filtered in fused salt are by media flow alluviation in the bottom of fused salt filter vat, Awaiting Overhaul
When remove.
Wherein, filter device may filter that impurity using upright type of design, and aperture can utilize media flow cleaning filtering on side wall
Hole avoids blocking；It vertically-arranged and is extended downwardly in filter device inlet tube tank, vertical staving large area aperture can make medium temperature in tank
Degree more evenly, can also effectively extend clear deimpurity time interval.The pipeline of connection staving is set as the flaring structure of reamer section
Form can make distribution more evenly and reduce filtration resistance.
Ring flange of the closed end 3033 of 303 bottom of vertical filter unit preferably by being fixed on vertical filter unit bottom
The blank flange composition removably being connect with ring flange, however, the present invention is not limited thereto.Fused salt emptying is provided on blank flange
Hole blank flange removed to prevent fused salt from gathering and thin salt, when system shutdown overhauls remove lodge in impurity in filter vat and
Solid particle, structure is easy to disassemble and clears up.
According to requiring, system need to guarantee the fused salt for having a constant volume in tank when running, i.e., keep certain fortune in control tank
Row liquid level and the suitable level fluctuation range of setting.In order to reduce the design volume of import surge tank, fused salt is exported into tube assembly 4
Input end the position in import surge tank close to lower part is set, fused salt in tank can be utilized to greatest extent；Fused salt outlet group
Surge tank ontology is drawn in the middle and upper part (near minimum liquid level) that part extends upwardly to import surge tank in import surge tank again, this
Sample can reduce external pipe dosage, and vertically-arranged and upwardly extend, can not be pressurized and can reduce pipe outlet in tank
Road heat tracing and thermal insulation material, and exempt heat preservation on the outside and tracing system.
Local vibration when in order to avoid operation, surge tank ontology 1 are internally provided with to fused salt import tube assembly 3 and fused salt
The support component that outlet tube assembly 4 fixes, such as fused salt inlet tube support component 7 and fused salt outlet support component 8.
In addition, fused salt outlet tube assembly 4 can be designed using existing conventional structure, only above-mentioned want need to be met on setting position
It asks.Specifically, fused salt outlet tube assembly 4 also includes the tube socket being arranged on surge tank ontology 1, and fused salt exports the pipe of tube assembly 4
Seat can also be connect by welding manner with outside pipe arrangement.
Between the starting of fused salt heat absorber system and spinning period, the fused salt in surge tank do not enter fused salt heat dump heating surface and
It is that decline guard system is removed through bypass pipe, so surge tank ontology bottommost of the invention is disposed with fused salt bypass tube assembly 5, system
It is also to be emptied fused salt in tank by this pipeline when stoppage in transit.
According to heat absorber system process, when normal operation in surge tank fused-salt medium exported tube assembly enter heat dump by
It absorbs heat in hot face.When fused salt failure of pump, it need to guarantee that the fused salt retained in import surge tank can smoothly enter into heat dump heating surface
It is interior, compressed air inlet stub (tube) is also equipped at the top of surge tank ontology according to this requirement present invention, it is empty to introduce compression
Gas extrudes fused salt in tank from outlet tube assembly as power source.In addition, the top of surge tank ontology 1 is additionally provided with maintenance manhole
10, so that staff can enter and leave in failure or when needing to remove filtrate in vertical filter unit import surge tank and carry out
Trimming.
In conclusion not only can effectively solve the problems, such as fused salt working medium filtration, purification and reasonable distribution after present invention application, also
Eliminate the inconvenient problem of heat preservation, tracing system and dismounting, the maintenance of external filter complexity, be finally reached investment reduction and
Reduce maintenance cost purpose.
The invention is not limited to specific embodiments above-mentioned.The present invention, which expands to, any in the present specification to be disclosed
New feature or any new combination, and disclose any new method or process the step of or any new combination.
