The pumping rate of a pumping draught fan is divided into a high and a low gears. The ranges of measurement of the ion concentration and the mobility are increased. The resolution and the measuring accuracy are raised. The utility model can cover various checking of big, middle and small ions and matches with corresponding equipment. The utility model is a precise and perfect checking facility for departments of air ion study and application.
Description
The utility model belongs to electrostatic separation and air ion measurer.
The air ion gatherer generally adopts the ion in the electric field collection gas, and ionic charge is changed into electric current.
Existing air ion gatherer has garden cartridge type, parallel plate type etc., parallel utmost point formula air ion gatherer adopts primary structure (being a pair of collecting board and polarising sheet) or secondary structure (i.e. the two pairs of collecting boaries and polarising sheet, but forward and backward level polarising sheet does not separate).Its shortcoming is that the ion concentration measurement scope is little, and resolution is low, and the mobility measurement range is narrow.
The ion trap that BECKETT type air ion number that U.S. DEV company produces nineteen eighty-three and mobility measures instrument are adopted is the secondary parallel plate type, and two pairs of collecting boaries and polarising sheet are arranged, but forward and backward level polarising sheet is not separately, in fact has only a polarising sheet.Its ion concentration measurement scope is 0～6.7 * 10
8Individual ion/cm
3The about 30/cm of resolution
3The mobility measurement range is 0.14,0.011,0.0036(cm
2/ VSec, third gear); The speed of exhaust is one grade of 38cm/Sec().
The utility model proposes a kind of expansion ion concentration measurement scope and mobility measurement range, improve resolution, the speed of exhaust is two grades a secondary parallel plate type air ion gatherer.
The air ion gatherer partly is made up of forward and backward level gatherer, insulcrete, back up pad, blower fan etc.The prime gatherer comprises collecting board (1) and polarising sheet (2), and back level gatherer comprises collecting board (3) and polarising sheet (4).Collecting board and polarising sheet adopt the multi-disc electrode plate structure, making multiple-piece intermeshes, parallelly assembles, be fixed on the back up pad (6) that links to each other with shell by insulcrete respectively, the outside of back up pad is the metal shell of shielding usefulness, therefore, increase collecting amount, improved the sensitivity of complete machine significantly, improved signal to noise ratio (S/N ratio).The pole plate of prime gatherer is shorter, and general length can select 5～8(cm), is used to collect small ion.The pole plate of back level gatherer is longer, is generally 30～50(cm), is used for collecting big, intermediate ion.Forward and backward level not only collecting board separately, polarising sheet also separates, it can be freely applies different polarizing voltages to the polarising sheet of forward and backward level.When measuring small ion, prime is as ion trap; When measuring big, intermediate ion, the back level is as ion trap, and prime is used as the small ion filtrator, in advance with the small ion filtering, to improve the degree of accuracy of measurement result.
In order to overcome the influence of " fringe field ", the collecting board of prime (1) is ahead of polarising sheet (2) slightly.
Forward and backward level polarising sheet can add different polarizing voltages respectively, to satisfy different test needs; Also can be linked together, make their polarizing voltage change consistent by external control circuit.
The speed of exhaust of blower fan (7) is divided into high and low two grades, control by external circuit, top gear is used to measure the small ion of air background values, low or first gear is used for measuring big, intermediate ion, can make that so not only the ion mobility scope is expanded, and can adapt to the test events that the sampling air mass flow had different requirements.
Tested gas air pump suction ion trap, in ion trap, utilize the entrained electric charge of polarized electric field collection of ions between collecting board and the polarising sheet, measure the formed electric current of these electric charges with microgalvanometer, by gas sampled flow value and microgalvanometer reading, can record the ion concentration value.Change the polarity of polarizing voltage, can change the ion polarity of measurement.Change parameters such as polarizing voltage size, pole plate length and the speed of exhaust, can change the ion mobility value.The utility model is owing to adopt forward and backward level gatherer to separate fully, be that forward and backward level collecting board separates, forward and backward level polarising sheet also separates, and two kinds of speed of exhausts, thereby increased the ion mobility measurement range, improved resolution and measuring accuracy, and taken into account the requirement of the different sampling amounts of ion concentration, can measure the parameters such as polarity, concentration and mobility of air ion, cooperate corresponding miscellaneous equipment can obtain the ion concentration measurement scope and reach 1～1.999 * 10
9(individual/cm
3), resolution is 1(/cm
3), the ion mobility measurement range can reach 3～0.001(cm
2/ VSec), detection that can topped large, medium and small various ions is a kind of comparatively accurate and perfect detection means of the air ion research and the department of application.
