Description

one

The invention relates to the field of protection against the effects of charges of static electricity and can be used to neutralize the charges formed on threads, fabrics, films and other highly electrifying materials.

A device for neutralization of static electricity is known: containing rows of needle-like discharge electrodes forming an alternating voltage converter G1.

Closest to the invention is a device for neutralizing static electricity charges on moving materials, comprising a body and a series of electrodes of the tips of an induction neutralizer and at least one row of electrodes — the tips of a high-voltage neutral-Glyser.

Its disadvantage is relatively low efficiency due to the limited discharge currents of the high-voltage neutralizer.

The aim of the invention is to increase the efficiency of neutralization.

This goal is achieved by the fact that in a device for neutralizing the charge of -1DON of static electricity on

moving materials containing a body and a series of electrodes — tips of an induction neutralizer and at least one row of electrostatic high voltage neutralizers. A series of electrodes — the tips of a high-voltage neutralizer — is installed in the gap between the rows of electrodes of an induction neutralizer. Besides

fO addition, dielectric partitions are installed between the rows of electrodes.

The drawing shows a cross-section of the device.

15 It consists of. housing 1, a series of electrodes, spikes 2 induction neutralizer, a number of electrodes, spikes 3 high voltage neutralizer.

The rows of electrodes are divided between 20 dielectric partitions 4.

 The device works as follows.

When moving the charged moving material near the edges, the air is ionized both due to the occurrence of a discharge from the grounded edges of the induction neutralizer and from the edges of the high-voltage neutronizer. The resulting charges neutralize the charge on the surface of the material.

Due to the proposed design of the device, the charged material in the process of moving enters primarily into the zone of action of the induction neutralizer. The large potential difference between the material and the wasps of rims 2 ensures the occurrence of a sufficiently intense discharge from these points and the neutralization of the main part of the charges. The remaining part of the charge enters the zone of action of the high-voltage neutralizer, where it is neutralized due to the relatively weak high-voltage discharge.

The installation is sufficient (Yudnogo series of electrodes of the induction neutralizer, but the neutralizer must be installed in such a way that the charged material comes first to the operating area of the induction neutralizer.

The proposed device makes it possible to obtain a sufficiently high efficiency of charge neutralization on moving materials at noticeably lower voltage levels at a high-voltage neutralizer, which helps prevent the formation of ozone and greatly simplify the design of the device.
