Description
Technical field
The utility model relates to safety feature, particularly is used in nuclear power station hydrogen pipeline safety feature.
Background technology
Hydrogen, is widely used in fields such as energy source and power, petrochemical complex, electronic apparatus, food processing, Aero-Space because of its good combustibility and reductibility as a kind of energy fuel and industrial chemicals of clean and effective.Simultaneously, because the inflammable and explosive and colorless and odorless of hydrogen, in case generation is leaked then is very easily caused security incident in production run.In the nuclear power industry, hydrogen often is used to the deoxygenation technology of demineralized water or is used as the heat eliminating medium of turbodynamo, for guaranteeing the safety of personnel and plant and equipment, Hydrogen Line, equipment place factory building must be provided with that hydrogen is surveyed and the safety dumping system, so that in time report to the police during hydrogen gas leakage and close the hydrogen pipeline valve automatically, open air exhausting device.Existing hydrogen is surveyed and there is following shortcoming in security system: it is more and distribute scatteredly to relate to the pipe joint of hydrogen, and when several joints leaked simultaneously, the big and local concentration of hydrogen gas leakage amount formed accident potential less than alarming value; Hydrogen density mainly is distributed in the factory building top far below air after the leakage, because the space is bigger in the factory building, the unavoidable existence detected the dead angle, brings potential safety hazard; The electric device such as valve, motor, instrument and the opertaing device etc. that are arranged in the same factory building all need adopt explosion-proof series, have increased cost.Therefore, it is very necessary to design a kind of used in nuclear power station hydrogen pipeline safety feature simple in structure, with low cost, reliable, easy to maintenance.
Summary of the invention
The purpose of this utility model provides a kind of used in nuclear power station hydrogen pipeline safety feature simple in structure, with low cost, reliable, easy to maintenance.
For achieving the above object, the utility model adopts following technical scheme: a kind of used in nuclear power station hydrogen pipeline safety feature, comprise sealed cabinet, the hydrogen detection instrument, explosion-proof fan and controller, it is characterized in that being provided with in the sealed cabinet space of arranging hydrogen pipeline and measuring instrument thereof, the cabinet of sealed cabinet and cabinet door cooperation place are provided with sealing strip, offer the outlet of hydrogen tube inlet and hydrogen pipe on the sealed cabinet, be respectively arranged with O-ring seal in hydrogen tube inlet and the outlet of hydrogen pipe, be provided with explosion-proof electrically-controlled valve in the sealed cabinet, external hydrogen pipe is connected with the import of explosion-proof electrically-controlled valve after entering sealed cabinet through the hydrogen tube inlet, the outlet of the explosion-proof electrically-controlled valve hydrogen pipeline inlet interior with being arranged in sealed cabinet is connected, the hydrogen detection instrument is fixed on the top of sealed cabinet, the air inlet of explosion-proof fan is connected with the top of sealed cabinet, the both sides of sealed cabinet are provided with interior air intake window shutter, the cabinet door of sealed cabinet is provided with view window, the signal output part of hydrogen detection instrument is connected with the signal input part of controller, and the signal output part of controller is connected with the control end of explosion-proof fan and explosion-proof electrically-controlled valve respectively.
Further, in such scheme, described sealed cabinet is provided with electrostatic grounding mechanism.
Further, in such scheme, described explosion-proof electrically-controlled valve has two at least.
Further, in such scheme, described view window is tempered glass or transparent plastic.
In sealed cabinet, there is not leakage in the pipe joint of sealed cabinet external cause no hydrogen to the utility model, has both guaranteed safety with the equal centralized arrangement of all pipe joints of hydrogen pipeline system, can reduce the equipment configratioin requirement of non-hydrogen pipeline system again; Sealed cabinet Nei Zeyin space is less relatively and do not exist and detect the dead angle, and can just start the safety dumping system during far below its explosion limits at density of hydrogen.The utility model is simple in structure, with low cost, reliable, easy to maintenance.
