The specific embodiment
Be described in further detail below in conjunction with accompanying drawing 1 and 2 couples of the present invention of accompanying drawing.
Referring to Fig. 1 and Fig. 2, before jar sodium begins, needing will to adopt the sodium container by a movable joint c is connected with primary cleaning cold-trap a inlet, by No. two movable joint d primary cleaning cold-trap a outlet is connected with connection pipe e, connection pipe e is connected with the import and export of sodium jar g metallic sodium by No. three movable joint f.
Equipment connect finish after, should with displacement air wherein, and be respectively primary cleaning cold-trap a by admission port 4 for entire equipment charges into the argon gas of lower pressure, sodium jar g and connecting tube e twine heater strip, heat-preservation cotton, and in position arrange thermocouple.
After heating and heat-insulating device installs, heater strip is powered, be system warm-up, when treating that system's each several part temperature all reaches between 200 ℃-300 ℃, think and satisfy a jar sodium condition by pressure regulator.
Open and adopt the sodium container and put the sodium valves door, liquid metal sodium will be flowed into by the liquid metal sodium inlet b of primary cleaning cold-trap a, the primary cleaning cold-trap a that flows through successively, and connection pipe e enters sodium jar g.Injection along with liquid metal sodium, low level probe 8 cooresponding indicator lamps at first brighten, need to observe sodium jar g tank body thermocouple readings this moment, guarantee that they are about 200 ℃, and opening exhausr port 2 valves exits gradually, keep sodium jar g and adopt difference of pressure between the sodium container, regulate discharge quantity and venting speed by compression indicator 3 readings.When treating that high level probe 9 corresponding indicator lamps brighten, close and adopt the sodium container and put the sodium valves door, and close exhausr port 2 valves, stop a jar sodium.
As have only a sodium jar, can open movable joint c respectively No. one, No. two movable joint d, near heat-preservation cotton No. three movable joint f are so that above-mentioned position comparatively fast cools off, when treating that temperature drops to 50 ℃, can separate movable joint, and use the mating endcap sealing, the equipment each several part of making breaks away from mutually.
If any a plurality of sodium jars, then only need to accelerate near the rate of cooling the movable joint f No. three, sodium jar and system are broken away from, thereby change next sodium jar, can continue a jar sodium.
Sodium jar for breaking away from from system need charge into the argon gas of certain pressure to it by admission port 4, and is isolated to guarantee metallic sodium and air.Treat that the sodium jar is cooled to normal temperature, think that a jar sodium process finishes.
After jar sodium is finished, the sodium jar can be encapsulated, transport by professional transport vehicle.
As needs metallic sodium is stored, then can directly in the sodium jar, store,, can guarantee that metallic sodium is well stored as long as the routine observation argon pressure replenishes argon gas when insufficient pressure.
As needs metallic sodium is filled in special container or the loop and uses, each equipment of connection and heating and heat-insulating device when then only needing still according to jar sodium.Difference just charges into argon gas by admission port 4, keeps sodium jar internal pressure to be higher than the perfusion that the target container internal pressure can be finished sodium smoothly.Also the sodium jar can be directly connected on the loop, use as the part in loop.
This liquid metal sodium transportation storage facilities has passed through the check of practical operation, prove its installation, debugging, use, operate all as safe as a house, reliable, convenient, and can provide good condition of storage by the liquid towards metallic sodium, safety also can be fully guaranteed in the transportation, is suitable as very much the transportation storage facilities of liquid metal sodium.
Above content is to further describing that the present invention did in conjunction with concrete preferred implementation; can not assert that the specific embodiment of the present invention only limits to this; for the general technical staff of the technical field of the invention; without departing from the inventive concept of the premise; can also make some simple deduction or replace, all should be considered as belonging to the present invention and determine scope of patent protection by claims of being submitted to.
