Technical background
The radioaerosol monitoring is one of important content of Nuclear Accident Emergency monitoring; Its objective is and in time obtain aerocolloidal concentration information in the air; The purification of radioaerosol and protection provide scientific basis when rescuing for Nuclear Accident Emergency; With protection Environmental security and personnel health, also can be the inverting accident source term foundation is provided.
Current, to participate in the Nuclear Accident Emergency rescue task and need get into when examining the contaminated area, the land often will rely on the nuclear emergency relief car, and will rely on nuclear emergency rescue shelter at sea.The sampling filter paper chart drive assembly of existing radioaerosol monitor, nuclear detector unit and sampling are imported and exported general all outside at cabinet, and especially filter paper and detector are not sealed in cabinet inside.Carry out radioaerosol like this in the nuclear contaminated area when measuring, need personnel to change filter paper or carry out other necessary operation, thereby increase chance and the time that the emergency personnel accepts nuclear pollution.Therefore, existing aerosol monitoring appearance can't satisfy pressing for that the enforcement radioaerosol is monitored in the crash programme zone under the Nuclear Accident Emergency rescue conditions.
Summary of the invention
The purpose of the utility model is can not satisfy the practical problems of in the crash programme zone, implementing the radioaerosol monitoring under the Nuclear Accident Emergency rescue conditions to existing aerosol monitoring appearance; The radioaerosol monitoring equipment of one cover based on energy discrimination method is provided, and can be applied to the monitoring of radioaerosol in the crash programme zone.
For realizing above-mentioned practical problems, the utility model is taked following technical scheme:
A kind ofly be applicable to the real-time device for monitoring of radioaerosol in the Nuclear Accident Emergency plan district; Comprise gas sampling system, the Nuclear Detection System in the cabinet and walk paper system; Said gas sampling system comprises; Gas is sucked by sampling head, and the sampling line of flowing through, sampling filter paper, filter paper pallet and electronic flow-meter are discharged by aspiration pump at last; Said Nuclear Detection System comprises; Electric signal by the output of PIPS semiconductor detector at first tentatively amplifies through charge amplifier; Further be amplified into the multichannel pulse amplitude analysis system through linear amplifier again, final measurement is shown by display, is exported by communication interface; The said paper system of walking comprises, by the control circuit drive motor, the filter paper in the strainer storehouse is moved along filter paper pallet and filter paper fault sensor, finally gets into sample bin.
Aforesaid radioaerosol monitoring device; The enclosing cover of its casing can be opened; Carry out the replacing of filter paper; And have excellent sealing performance after closing, can be in cabinet with Nuclear Detection System and paper feed system sealing, and the sampling head of gas sampling system, aspiration pump and gas vent are all in the cabinet outside.
Whole box body of the utility model and aspiration pump can be placed in land nuclear emergency relief car or boat-carrying nuclear emergency rescue shelter is inner; Simultaneously can the sampling head of gas sampling system and gas outlet be placed in land nuclear emergency relief car or boat-carrying nuclear emergency rescue party portion out of my cabin, thereby can avoid the nuclear emergency rescue personnel to go out to change filter paper or carry out other necessary operation and accept nuclear radiation and endanger through prolonging pipeline.
