Problems solved by technology

Its disadvantages are: firstly, the air ion measuring instrument cannot measure normally in a high-humidity environment (relative humidity ≥ 60%); secondly, the electric field formed by the winding of the heating wire will interfere with the normal detection of air ions; finally, the instrument using 220V AC PTC has certain dangers
[0003] To sum up, so far, no matter at home or abroad, it is still an unsolved problem to enable the ion detection device to measure normally in a high-humidity environment (relative humidity ≥ 80%)

Embodiment Construction

[0031] With reference to Fig. 1 and Fig. 2, ion detecting device of the present invention comprises: shell, ion collector 11, charge amplifier (also called weak current amplifier, preamplifier, preamplifier) ​​12, computer automatic control mainboard and uninterruptible multi-purpose power supply , the ion collector 11 is a barrel-type ion collector, and a barrel-shaped ion-collecting plate (also called an ion-collecting plate) 26 and a barrel-shaped ion polarizing plate (also called an ion bias plate, ion Pressure plate) 22, is characterized in that,

[0032] 1. Do moisture-proof and dehumidification treatment on the ion polarization plate and ion collection plate.

[0033] The insulating base 25 of the ion polarizing plate 22 and the insulating base 27 of the ion collecting plate 26 are wound with a low-voltage electrothermal film, a metal film resistor or an oxide film resistor to form non-closed heating bands 24, 28, and select a suitable heating temperature , to heat the...

Abstract

This invention provides one ion test device humidity remove method and its test device, wherein, the method comprises the following steps: a, processing anti-humidity and remove on polarization insulation socket; b, processing air isolation on charge amplifier or anti-humidity; c, processing the end anti-humidity, insulation and remove connected to the shield signal wire and ion collection board. This invention processes anti-humidity and remove and insulation through ion polarization board, ion collection board, charge amplifier and shield signal wire end.

Description

technical field [0001] The invention relates to a moisture-proof and dehumidification method for an ion detection device in a high-humidity environment and an ion detection device using the moisture-proof and dehumidification method. Background technique [0002] Although some moisture-proof and dehumidification design structures are used in the existing various ion detection devices, there are fundamental defects, that is, in a high-humidity environment (relative humidity ≥ 60%), it can only collect normally for a short time or cannot collect normally at all. For example, the anti-moisture design structure adopted in the existing air ion measuring instrument (authorized announcement number CN 1181338C) is: the insulating base of the ion collection plate is wound with an electric heating wire and heated with a base plus a PTC ceramic heating device (~220V). method. Its disadvantages are: firstly, the air ion measuring instrument cannot measure normally in a high-humidity en...
