Description
Technical field
The utility model relates to the detection of gas field, particularly a kind of diffused hydrogen surveymeter.
Background technology
In the steam generator accident protection system design of sodium-cooled fast reactor,, must adopt the main means of hydrogen meter as the sodium-water reaction early detection in order in time to find the leakage of water in sodium.A kind of detection instrument that the diffused surveymeter is sensitive as a comparison is widely used in each sodium-cooled fast reactor, as French Phenix fast reactor, respectively is provided with a cover hydrogen surveymeter at evaporator, superheater, reheater outlet and expansion tank deck.But existing diffusivity surveymeter General System complexity, bulky, the response time long, inconvenient maintenance, equipment install and layout aspect be subjected to a lot of restrictions.
Summary of the invention
The utility model has overcome the deficiencies in the prior art, provide a kind of simple in structure, volume is little, the response time is short, piping arrangement is simple, diffused surveymeter easy to maintenance.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
This system comprises sampling pipe, regenerator, nickel pipe, well heater, vacuum system, the interior tube inlet of regenerator, outer tube outlet connect sampling pipe respectively, the interior pipe outlet of regenerator is connected with well heater, the outer tube inlet of regenerator is connected by pipeline with nickel Guan Yiduan, the nickel pipe other end is connected with well heater, the nickel pipe is connected with vacuum system, and clamping has electromagnetic pump on the described sampling pipe.
In order to shorten the response time of hydrogen meter greatly, make piping arrangement simpler, sampling pipe described in the utility model shortens to 1～2 meter, and described nickel pipe diffusion area is 50～85cm
2
Compared with prior art, the beneficial effects of the utility model are: this system adopts the external clamping electromagnetic pump, directly utilizes pipeline as the pump ditch, need not weld, be convenient to maintenance, and the bigger volume that dwindled, sampling pipe length is 1～2 meter simultaneously, makes structure simpler.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
This system is by sampling pipe 1, regenerator 3, nickel pipe 5, well heater 4, vacuum system 6, the interior tube inlet 7 of regenerator 3, outer tube outlet 8 connect sampling pipe 1 respectively, the interior pipe outlet 9 of regenerator 3 is connected with well heater 4, the outer tube inlet 10 of regenerator 3 is connected by pipeline with nickel pipe 5 one ends, nickel pipe 5 other ends are connected with well heater 4, and nickel pipe 5 is connected with vacuum system 6.Clamping has electromagnetic pump 2 on sampling pipe 1, and electromagnetic pump 2 can be arranged on any sampling pipe 1, perhaps respectively is provided with one on two sampling pipes 1, and present embodiment is arranged on outer tube and exports on 8 pipelines that link to each other.This systematic sampling pipeline 1 length is 1～2 meter, and present embodiment adopts 1.5 meters sampling pipe 1; Nickel pipe 5 diffusion areas are 50～85cm
2, present embodiment adopts 85cm
2Nickel pipe 5; The pumping speed of vacuum system 6 is 25～50L/S, and present embodiment adopts the vacuum system 6 of 35L/S.Be connected to welding in the system between each parts.
The hydrogen surveymeter is introduced sodium stream with electromagnetic pump 2 by long 1.5 meters sampling pipe 1 from trunk line, enter regenerator 3 by interior tube inlet 7 and carry out heat interchange with the high-temperature sodium that enters regenerator 3 backflows by outer tube inlet 10, then by entering nickel pipe 5 after well heater 4 heating, and the hydrogen in the sodium to pass diffusion area by infiltration be 85cm
2Nickel pipe 5 in the nickel film be diffused into the vacuum system 6 that pumping speed is 35L/S, vacuum system 6 keeps high vacuum state, the variation of hydrogen richness in the sodium can be surveyed by the variation of electric current, and then water or water vapor can be surveyed to the leakage of steam generator sodium side and the size of leakage rate.Simultaneously sodium stream is got back in the trunk line by outer tube outlet 8 after entering regenerator 3 and the sodium heat exchange that enters by interior tube inlet 7 by outer tube inlet 10, finishes detection at last.
