Background technology
The equipment that uses during the adsorption efficiency of nuclear power station iodine adsorber efficiency test sample analyser is a nuclear power station in check ventilating system iodine adsorber.This equipment adopts radiation detector to do quantitative test through the gamma-ray measurement that iodine 131 is discharged, to confirm the adsorption efficiency of iodine adsorber.At present, to the iodine adsorption efficiency in nuclear power station ventilating system test, use be that general energy spectrometer is as the actinometry instrument.Testing crew is transported to the instrumentation place at energy spectrometer place through the on-site collection sample during test, and to obtain the activity information of iodine-131, testing crew draws the adsorption efficiency of one group of sample again through manual calculations then through spectral measurement.There are following two shortcomings in this energy spectrometer:
1. the sample of fetching from the scene; Not can both in time be placed in the energy spectrometer system to measure, can be because the existence of sample resting period causes the activity measurement result to need to revise; Possibly lose best Measuring Time for the measurement of the more weak sample of activity, increase the error of measurement result;
2. when data analysis and processing, all need extra manpower and materials to accomplish, staff's working strength is big, and has increased the financial cost of test.
Summary of the invention
The purpose of the utility model is: provide that a kind of compact conformation, automaticity are high, function is with strong points, safeguard nuclear power station iodine adsorber efficiency test sample analyser easy to use.
The utility model is such realization:
Nuclear power station iodine adsorber efficiency test sample analyser includes locomotive, and is arranged on switch board and sample measurement chamber on the locomotive, it is characterized in that; Said sample measurement chamber; By shell, be contained in cylindrical hollow vitriol chamber in the housing, be contained in the radiation detector in the vitriol chamber cavity and be arranged on specimen holder and the frame on the radiation detector entrance window specimen and form, wherein radiation detector links to each other with switch board through the cinclides that cable passes on vitriol chamber and the shell; Said switch board is made up of the power-supply system, signal amplifying system, signal data acquisition card and the Computerized analysis system that are contained in the cabinet; Wherein signal amplifying system links to each other with the signal data acquisition card through cable, and the signal data acquisition card links to each other with Computerized analysis system through cable; Being connected between sample measurement chamber and switch board, be meant that the radiation detector in the sample measurement chamber links to each other with signal amplifying system in the switch board through cable.
Radiation detector in the said sample measurement chamber, can be in scintillation detector, semiconductor detector or the ionization detector any.
The utility model has following advantage than prior art:
1. compact conformation is convenient to move, can be easily that equipment delivery is on-the-spot to sample collection, and, in time measures by sample when being collected into to obtain the optimum measurement result, improved the accuracy of measurement result;
2. can carry out analyzing and processing to sample data in real time, accomplish the result of calculation that can provide relevant adsorption efficiency after measuring, reduce staff's working strength and test financial cost.
