Description
Technical field
The utility model relates to technical field of waste gas treatment, particularly the online radiation monitor of a kind of nuclear power station exhaust treatment system.
Background technology
Nuclear power station, spentnuclear fuel treatment plant etc. can produce radioactivity inert gas in operational process, and these radioactivity inert gases enter air after usually being collected process by exhaust treatment system.Carrying out online Radiation monitoring to this system, understand exhaust radioactivity total activity or instantaneous activity concentration in time, realize the effective control to exhaust, is the necessary means avoiding nuclear power station surrounding environment to be subject to polluting, ensureing nearby residents safety.To the radioactivity monitoring of exhaust treatment system, the p ray measuring radioactivity inert gas transmitting contained by it is one method directly and accurately.But due to the short range of p particle, this requires that detector can directly touch object to be measured, therefore need sensitive for detector body to be placed in bleeder line inside.Containing hydrogen in the waste gas of usual exhaust treatment system, therefore the design of monitor also needs to consider the measure such as seal for pipe joints, electrical isolation.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of nuclear power station exhaust treatment system online radiation monitor.
