An electrostatic high-voltage electrode for ionizing the air, having a multiplicity of needle-shaped individual electrodes (9) which are arranged in a plurality of like rows (6, 7, 8) and which each have a point (10), all the individual electrodes (9) being alike in construction and extending parallel to one another and their points (10) lying in one plane, and furthermore the individual electrodes (9) have a distance apart which is at least equal to half their free length (13), characterized in that the free length (13) of the individual electrodes (9) is in the ratio of at least 50:1 to their diameter, and that situated opposite the individual electrodes in the one row are the gaps between the individual electrodes of the adjacent rows.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention provides a method for ionizing air with a plurality of needle-like individual electrodes, each with one pointed tip, arranged in at least one row. Regarding high voltage electrodes.

[Conventional technology]

This -ship type electrode is known in a number of embodiments, especially for ionizing air.

[Problem that the invention seeks to solve]

However, all known electrodes have the disadvantage of generating ozone during operation to a highly undesirable extent.

The technical problem that the invention seeks to solve is to provide a high-voltage electrode of the same general type, which allows the production of as little ozone as possible during operation.

[Means for solving problems]

The technical measures taken to solve the above technical problems are:
All individual electrodes before implantation have the same shape, their tips lie in the l-plane, and the ratio of free length to diameter of said individual electrodes is at least 50:1, and
Each of a plurality of identically shaped columns has a plurality of individual electrodes,
Thereby, the individual electrodes in one row are arranged in a staggered manner with respect to the individual electrodes in adjacent rows, and the individual electrodes are arranged at least 1/2 of their free length apart. It is.

[For production]

The above technical means works as follows.

A plurality of individual electrodes of the same shape with a free length 50 times the diameter are arranged so that their tips lie in one plane before implantation.
The individual electrodes are arranged in a plurality of rows having the same shape, and the arrangement of the individual electrodes between adjacent rows is a staggered arrangement with an interval of 172 free lengths.

〔Effect of the invention〕

Therefore, the present invention has the following effects.

The total length of all the individual electrodes that make up this high-voltage electrode is extremely long, and there are no sharp tips or corners other than the tips of the individual electrodes, that is, other irregular points. We have now been able to provide long high voltage electrodes that are accurately arranged with an extremely simple structure, and to minimize the generation of ozone during operation.

〔Example〕

Next, embodiments of the present invention will be described in detail based on the drawings.

The high-voltage electrode (5) for ionizing the air consists of a number of individual electrodes (9), each with a very sharp tip (10), each of which is made of narrow rectangular electrically insulating material. The substrates are arranged parallel to each other in three parallel rows (6), (7), (8) in the form of printed circuit boards. All these individual electrodes (9) lie in one plane extending at right angles to their length. 1 row (6)
The space between the individual electrodes (9) in the adjacent rows (7

All the individual electrodes in one column as well as in several columns are connected to a negative high voltage power supply (not shown).

The individual electrodes (9) are located on the longitudinal sides of the printed circuit board (8) (
a free length (13) defined as a longitudinal portion extending vertically outwardly beyond said tip (10) and extending inwardly from said tip (10) beyond said side face (14) to said wax contact (12);
), and therefore has a total length that includes the free length and is greater than this (FIG. 5).

The ratio between the free length (13) of said individual electrodes (9) and the diameter of the individual electrodes is at least 50:1. Individual electrodes (9), (
9) They are also at least 1/2 of the total length of the individual electrodes.
