Background
The mainstream anion detectors can be divided into two types, namely a parallel plate type and a double cylindrical shaft type, according to different structures of the internal ion collector.
The detection principle of the parallel plate type is as follows: constant voltage is applied to a group of polarization electric plates which are equal to each other, then the air is sucked in through the electric plates by a rear-end fan, when the air flows between the flat plates, positive ions and negative ions in the air are influenced by torsion formed by the voltage between the electric plates and are respectively adsorbed by the corresponding electric plates according to different polarities, the ions adsorbed on the electric plates can cause the microwave change of the voltage of the electric plates, the change is recorded, so that the quantity of the collected ions can be converted, and the polarities of the ions can be distinguished.
A double cylinder shaft type air positive and negative ion detector is mature air ion detection equipment with a complex structure, and the current middle-high air ion detector basically adopts the structure. The double cylinder shaft type integral structure consists of 3 concentric cylinders, the outer cylinder body and the inner shaft are electrodes and apply constant voltage, and an air suction fan is arranged behind the cylinders. When the fan is started, air is sucked in through the cylinder, when positive ions and negative ions in the air flow through the cylinder, the positive ions and the negative ions are adsorbed to the cylinders with different polarities under the influence of torsion force formed by the voltage of the cylinder and generate discharge, and the discharge signals are recorded, so that the quantity of the positive ions and the negative ions in the air is calculated.
Since the time of existence of positive and negative ions in air is short, negative ions have a lifetime of several minutes in clean air, and have only a few seconds in dusty environments, air pretreatment cannot be performed at the time of measurement, and therefore, regardless of the collector, it is required to directly suck air in an open external air environment for measurement. The external air environment is severe in many places, and dust, insects, sundries and moisture are easy to suck; the air positive and negative ion measuring instrument belongs to a high-impedance micro-current measuring instrument and is very sensitive to environmental humidity and foreign matters. Particularly, the ion trap portion thereof is a part for sampling the atmosphere, and when the air is in operation and is subjected to a high moisture content (i.e., high humidity), the moisture in the air adheres to the metal trap plate and the insulator of the trap, so that the insulation between the trap plate and the housing is reduced, which may cause failures such as unstable readings, data overshoot errors, and the like.
