The utility model provides a pipe structure with high reliability, uniform heating, better thermal insulation, accurate temperature measurement and simple operation.
Description
Technical field
The utility model relates to metal pipeline field, particularly a kind of pipeline configuration of sodium-cooled fast reactor.
Background technique
The sodium-cooled fast reactor system adopts liquid metal sodium as heating medium, and the running temperature height is up to degree more than 500, and the quite work group of the chemical property of liquid metal sodium, very easily with empty G﹠W generation chemical reaction.Design is had higher requirement to system pipeline, not only will consider the sealing of pipeline, also will heating, insulation, sodium test leakage point and the temperature point etc. of pipeline be carried out thickly designing in week.At present, known to process pipe adopt the electrical heating wire of magnetic bead type, the life-span is shorter, and changes quite difficulty of electrical heating wire after the reactor operation, and adopts the short circuit of electrical heating wire to monitor sodium to leak, be unfavorable for independent control, operating difficulties.Other process pipe electric heating are to adopt perforate on pipeline, and with the electrical heating rod heating, point for measuring temperature also is to be stretched over pipe interior to measure, and cause the sealing of pipeline to reduce, and Safety performance is relatively poor.
Summary of the invention
The utility model has overcome the deficiencies in the prior art, and a kind of safe and reliable, homogeneous heating, good heat insulating, thermometric pipeline configuration accurate, simple to operate are provided.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: this pipe side wall comprises internal layer, mesosphere and skin, described internal layer is that the outer surface of Stainless Steel Tube is equipped with temperature thermocouple, twine electrical heating wire along circumference, electrical heating wire does not contact with temperature thermocouple, and sodium test leakage point is equipped with in Stainless Steel Tube tube wall bottom; Described mesosphere is the reflecting layer; Described skin is the protective layer that thermal insulation layer and surface thereof are laid.
In order to improve the efficiency of heating surface, working life, more evenly measured temperature is more accurate in heating to pipeline, and the utility model is all right:
Described electrical heating wire is the armouring electrical heating wire; The temperature thermocouple point is welded in the outer surface of Stainless Steel Tube; Described reflecting layer is that stainless steel foil is made.
Compared with prior art, the beneficial effects of the utility model are:
The utility model adopts advanced armouring electrical heating wire, longer service life, efficient height and safe and reliable, sodium test leakage point is installed in stainless steel tube wall bottom, the mesosphere is the reflecting layer, make electrical heating wire more even to the pipeline heating, leak the easier monitoring of sodium, thermometric thermocouple measured temperature is more accurate.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
This pipeline is closely cooperated by internal layer, mesosphere and skin and constitutes.Wherein internal layer adopts stainless-steel pipe 1, can select unlike material for use according to the difference of temperature, and according to the concrete condition of sodium-cooled fast reactor, present embodiment adopts 304L or 304H material to make, and 304L is used for the lower pipeline of temperature, and 304H is used for the higher pipeline of temperature.Be welded with temperature thermocouple 3 and reach sufficient with Stainless Steel Tube 1 outer surface at the outer surface point of Stainless Steel Tube 1 and contact, the outer surface at Stainless Steel Tube 1 is wound with advanced armouring electrical heating wire 2 simultaneously, and avoids temperature thermocouple 3.For the sodium of monitoring pipeline accurately leaks, sodium test leakage point 5 is installed in Stainless Steel Tube 1 tube wall bottom.Sodium test leakage point 5, electrical heating wire 2 and temperature thermocouple 3 are controlled separately, and be simple to operate.The mesosphere is the reflecting layer 6 that stainless steel foil is made, and makes the heating of the 2 pairs of pipelines of electrical heating wire more even, leak sodium easier monitor and temperature thermocouple 3 measured temperatures more accurate.Outer for to lay thermal insulation layer 4 and protective layer 7 outside reflecting layer 6, this thermal insulation layer 4 is selected environment protection type and the high nuclear level thermal insulation layer of insulating efficiency for use, has prevented the corrosion of material to greatest extent.The protective layer 7 of stainless steel foil is installed in outside the thermal insulation layer 4, and it is more even that thermal insulation layer 4 is installed, and pipe-line system cleans neatly more.
