Description
Technical field
The present invention relates to ionization chamber technical field, be specifically related to a kind of ionization device for gas detecting.
Background technology
Ionization chamber is the detector utilizing the ionisation effect of ionizing radiation to measure ionizing radiation, also known as ion chamber.Ionization chamber
It is made up of the electrode and medium therebetween being in different potentials.Ionizing radiation produces ionization ion pair in media as well, at electric field
Under effect, negative ions drifts about to negative pole and positive pole respectively, forms ionization current.Owing to ionization current just becomes with the intensity of radiation
Ratio, measures this electric current and i.e. can get the intensity of ionizing radiation.According to the kind of medium, ionization chamber can be divided into air ionization chamber, liquid
Volume ionization room and solid ionization chamber etc.；It is divided into impulse type ionization chamber and current mode ionization chamber according to measuring method.Ionization chamber kind
Various, except above-mentioned classification, also can be according to application, kinds of radiation, shape, gaseous species and pressure, measurement object, the school of measurement
Quasi-amounts etc. are classified.
Ionization chamber is the core of gas detecting PID, makes a general survey of the whole development course of PID, actually ionization chamber
Constantly updating the process optimized, the structure of ionization chamber directly affects the indexs such as the external volume of PID, detection efficiency, so
Need to use ionization chamber structure reasonable in design.And existing gas detecting ionization device volume is big, technical sophistication, detection efficiency
Low, unstable properties.
Summary of the invention
Present invention aims to defect and the deficiency of prior art, it is provided that a kind of simple in construction, reasonable in design, make
With the ionization device being conveniently used for gas detecting.
