Method for producing an ionization rod, and ionization rod produced according to the method

Abstract

The present invention relates to a method for producing an ionization rod and an ionization rod produced according to the method. The invention is characterized in that in a U-shaped duct profile (1) a main line (4) for supply current is placed, in that from this main line branch lines (3) are connected with adjacent carbon fibre brushes held in protective sleeves and in that a thermosetting plastic are laid into the duct profile covering the main part of the protective sleeves.

Claims

1. Method for producing an ionization rod comprising placing a main line for a supply current into a U-shaped duct, connecting the main line to adjacent carbon fibre brushes via main line branch lines, wherein the carbon fibre brushes are held in protective sleeves, and laying a thermosetting plastic into the U-shaped duct to cover part of the protective sleeves such that the carbon fibre brushes do not come into contact with one another during the laying of the thermosetting plastic.

2. Ionization rod produced according to the method of claim 1, wherein the ionization rod comprises a U-shaped duct, an active main line centrally located within the U-shaped duct, sleeves accommodating carbon fibre brushes positioned within the U-shaped duct, main branch lines electrically connecting the carbon fibre brushes to the main line; and a thermosetting plastic filling the U-shaped duct, thereby enclosing the sleeves.

Description

(1) The invention should now be described in connection with the embodiments shown in the accompanying drawing sheet, where

(2) FIG. 1 schematically shows a module that includes the ionization rod according to the invention,

(3) FIG. 2 shows several ion rods according to FIG. 1 in its positions in a fan unit included in the module, and where

(4) FIG. 3, in the upper part shows a section through the ion rod and where the lower part is a side view of the ionization rod.

(5) In FIG. 1 is accordingly schematically shown how the airflow through the module occurs. The airflow must be so adapted, via the selection of flow opening areas in and out of the module, that it reaches from only 20 cubic meters of air per hourin bedroomsto an air flow through rate of 5000 cubic meters of air per hour. The outflow opening is smaller than the inflow opening, which helps to create an overpressure over the fan unit to increase the separation of agglomerated pollutants.

(6) FIG. 2 shows the position of the ion rods in relation to the fan unit. The ion rods are accordingly located in a position where the flow direction is deflected to an axial flow through direction. It can be noted here that the brush ends of carbon fibre of the ionization rods are optimally exposed to the airflow. This ensures that the ions formed are effectively carried by the passing air. The ion rods can also be positioned so that the brush ends are directed perpendicular to the airflow. In both cases, the carrying of generated electrical charges is facilitated.

(7) FIG. 3 shows the ionization rod used in the present invention. Here the main line is protectively placed in an open channel profile. To the main line have been connected branch lines that support the brush ends of carbon fibre. The carbon fibres are collected in a sleeve where the electrical connection to the main line is ensured. The duct rail is filled with polyurethane or epoxy in such a way that the carbon fibre brushes are kept intact, i.e. do not comes into contact with this filling.

(8) The invention is not limited to the above-mentioned embodiments, but modifications can be made within the scope of the following specified claims.
