Description
Technical field
The present invention relates to heating equipment technical fields, more specifically to a kind of pre- for being heated to liquid alloy
Hot device.

The preheater for being presently used for lead bismuth alloy is mainly heated by heating element, and the temperature of lead bismuth alloy is made to reach
Process requirements.Conventional heating element includes electrode (being clipped in preheater both ends direct-electrifying), electric heating wire, electrically heated rod and silicon
Carbon-point etc..
The heating of electrode direct-electrifying is not suitable for lead bismuth alloy, since lead bismuth alloy has preferable electric conductivity, this side
Formula can be such that entire circuit charges, and resistance characteristic substantially increases the burden of this mode of heating；In addition oxygen control etc. is considered
Factor can make the wall surface of structural material will appear oxide layer, and which increase the uncertainties of resistance in electric heater section；Therefore directly
Electrified regulation is substantially infeasible for liquid state lead bismuth alloy experimental loop.
The heat flow density of electric heating wire is low, and when needing big temperature to rise, electric heating wire can be very long, causes cylinder (pipeline) corresponding
It is elongated, increase circuit resistance；If greatly improving the power density of electric heating wire, the temperature of electric heating wire can sharply increase,
This is added significantly to the manufacture difficulty of electric heating wire.
Elema is conductive, cannot be placed on inside preheater, can only prevent from carrying out radiating outside preheater changing
Heat, but this kind heat exchange and unstable, and need to make partiting thermal insulation cover, bulky, cost is higher；In addition Elema itself has
Failure characteristic, over time, the resistance characteristic of Elema can occur slowly varying.
Electrically heated rod can be customized with respect to that can bear higher temperature, heat bar shell body wall thickness for first three, appropriate to increase
The corrosiveness of lead bismuth alloy can be born for a long time by adding thickness, and rational deployment can then obtain higher heating power；
In addition releasable connection sealing can be used in heating rod, can be replaced after heating rod damage.
The heating part of some preheaters is the electric heating layer of material pipe outer cladding, and electric heating layer heat transfer also needs to lead to
Piping heat conduction, heat transfer efficiency is low, to obtain larger Wen Sheng, it is necessary to improve heat exchange area, this can cause material pipe elongated, return
Roadlock power increases；In addition, pipe external heat, thermal resistance is big, and heater strip own temperature improves, and increases heater strip manufacture difficulty, shortening adds
Heated filament service life；To save space, material pipe makes circuit resistance into one in broken line bending-type although having saved space
Step increases.
Also the sealing means of the end cap of some preheaters and heating rod are non-removable connection, once heating rod damages, very
Hardly possible carries out the replacement of heating rod；The preheater of liquid-state metallic sodium experiment loop is Pressure Vessel with Rectangular Cross Section, and pressure-resistant performance is not so good as
Cylindrical pressure vessel, and using equal amount material, volume is less than cylindrical pressure vessel；This kind is to be directed to liquid
The preheater that state metal is received, if being used for liquid lead bismuth alloy, practical application effect is unknown.
