Description
Technical field
The invention belongs to high temperature fluid pipe control field, and in particular to a kind of high-temperature fluorination thing fused salt experimental system pipeline
Control device.
Background technology
With the increasingly rise of fluoride molten salt fluid interchange research in the world, the reality using fluoride molten salt as working medium is built
Check system is essential.Therefore the flowing control problem for solving the fluoride molten salt in experimental system is needed, that is, realizes experiment system
The pipe control of system.
High yet with fluoride salt fusing point, corrosion mechanism is special, and the experimental system using fluoride molten salt as working medium is transported
Trip temperature is higher than 500 DEG C for a long time.Due to factors such as valve mechanisms, existing mechanical valve is difficult to effective operation, and practice have shown that
Mechanical valve reliability in fluoride molten salt experimental system is difficult to ensure that.
At present control aspect, existing many technical sides controlled using fused salt solidification come experimental channel are flowed in fused salt pipeline
Case.
Such as Chinese patent CN 202401166U provide a kind of melt freezing valve, it includes melt pipe and valve body, melt
Valve body is penetrated in the middle part of pipe and is tightly connected with valve body both ends, and melt pipeline does not have any interface, ensure that zero leakage of melt,
Melt pipe outer wall forms cylinder refrigerating chamber with valve interior wall, and cold air is passed through into refrigerating chamber can be so that melt solidification reaches only
Purpose is flowed, this valve mechanism is simple, easy to operate, but can not realize that pipeline quickly and effectively recovers unimpeded.
And for example Chinese patent CN 202612831U provide a kind of melt freezing valve, mainly by steam entrance sleeve, sky
Gas entrance sleeve, air outlet slit adapter, jacket pipe, inner connecting tube, overcoat and valve element composition, it is passed through the mixed gas of steam and air
Effective cooling can be carried out to the melt of valve element and cause its solidification, have the function that to close cut-off melt, but the valve body can not
Recover the unimpeded of pipeline, therefore be not suitable for being applied in the pipeline of frequent break-make.
For another example Chinese patent CN 105546164A provide the freezing valve that a kind of high temperature corrosion-resisting medium prepares purifier apparatus
Door, its mainly include valve body, introduction segment and export section, using the fin on valve body to inside liquid medium cooling down into
Solid-state, the closing of valve is realized, heating valve body can be to recover the unimpeded of runner, but the valve realizes work(using curvilinear conduit
Can, unnecessary flow resistance is introduced into, eventually brings larger negative effect to experiment, therefore is not suitable for being applied to villiaumite
In pipeline.
The content of the invention
It is real it is an object of the invention to provide a kind of high-temperature fluorination thing fused salt in order to overcome the above-mentioned problems of the prior art
Check system pipeline control device, the device are reliably and effectively realized pair by controlling solidification and the molten state of fluoride molten salt
The cut-off of fluoride molten salt pipeline and unobstructed control:Control pipe is flowed fast through in cavity using air, forms forced convection, it is fast
Quickly cooling but control pipe, solidify fluoride molten salt in pipe;Using the vacuum state in cavity, greatly organized by vacuum heat-insulation
Scattering and disappearing for tubular heat is controlled, along with the further insulation of heat-insulation layer so that heater strip can effective computer heating control pipe so that
Fluoride salt melts in pipe, allows control pipe to recover and keeps unimpeded for a long time.
The purpose of the present invention is to be achieved through the following technical solutions:
A kind of high-temperature fluorination thing fused salt experimental system pipeline control device, including control pipe F, close uniform winding is in control
The electrical heating wire C of pipe F outside wall surfaces, the sealing shell D being arranged on outside control pipe F, height is formed between sealing shell D and control pipe F
Closed toroidal cavity, gas inlet tube A and gas outlet tube H, gas inlet tube A and gas vent are provided with sealing shell D
Be respectively arranged with gas inlet valve B and gas outlet valve G on pipe H, in addition to the whole sealing shell D of parcel, gas inlet tube A,
The gas outlet tube H and heat-insulation layer E of control pipe exposed portion;High-temperature fluorination thing fused salt flows through control pipe F, by changing control pipe
The fusing of fluoride molten salt or curdled appearance realize pipe control in F;
When needing the fused salt flowing of prevention high-temperature fluorination thing, gas inlet valve B and gas outlet valve G is opened, electricity is closed and adds
Heated filament C, air at room temperature is injected from gas inlet tube A, then flowed out from gas outlet tube H, cooled down control pipe F, and then
High-temperature fluorination thing fused salt in control pipe F is solidified, reaches the purpose for preventing the flowing of high-temperature fluorination thing fused salt;
When needing to recover or keeping the flowing of high-temperature fluorination thing fused salt, start electrical heating wire C, close gas inlet valve B, beat
Gas vent valve G is opened, the air in sealing shell D is extracted out, makes the cavity vacuum in shell, turn off gas vent valve G afterwards,
Control pipe F heatings make fused salt in pipe recover or keep flowing.
The control pipe F is smooth seamless pipe, and from pipe import to outlet, caliber keeps constant.The sealing shell D is close
High temperature resistant stainless steel hollow cylinder is closed, control pipe F passes through its axle center, connected by welded seal, while sealing shell D and control pipe
The closed toroidal cavity of height formed between F, pumps wherein air, makes vacuum chamber as needed.The heat-insulation layer E by
The heat-insulating materials such as alumina silicate make.The gas inlet tube A and gas outlet tube H welded and installeds are on sealing shell D.
The present invention has advantages below and beneficial effect:
Property that 1. device difficulty of processing is low, cost is low and operation is simple and reliable is high.
2. control pipe F is straight line pipeline section, unnecessary flow resistance will not be introduced in fluoride molten salt flow process.
3. the vacuum chamber of device has high high temperature insulating ability, can ensure in whole experiment process at pipeline
In unimpeded state.
4. gas inlet valve and gas vent valve can be placed on the easily operated place of behaviour personnel, it is not necessary to which people is closely
Operation, make one away from system high temperature section, support personnel's safety.
