Description

The invention relates to a technique of protection against harmful manifestations of static electricity and can be used in various sectors of the national economy, in particular in the textile industry in the manufacture of rubber-fabric materials, plastic films, textile fabrics, etc.

The purpose of the invention is to increase the neutralization efficiency by introducing into the device a system for regulating the rate of ion intake to the corona electrodes.

The drawing shows the structural diagram of the device.

The device consists of a housing 1 made of a dielectric material, in the cavity of which is placed a metal perforated tank 2 with a working solution and a hygroscopic filler 3. Corona electrodes 5 of a hygroscopic material are brought out through the holes A in the case in the form of harnesses. Grounded electrodes 6 are placed in the housing. The tank is connected to a power source — a constant voltage generator 7. An additional wire grounded electrode located on the inner side of the housing near the outlets 4, is connected to the other pole of the power source - generator 7 of direct voltage.

The neutralizer works as follows.

When the processed material reaches an electrostatic field of the order of 1.5 kV, a corona discharge occurs at the ends of the corona-forming electrode 5 of a hygroscopic material as a result of inductive charging of the charge, which neutralizes the charge on the surface of the material being processed. In this case, under the action of an electrostatic field of an electrified material, from the ends of neutralizing electrodes of a hygroscopic material, the microdroplets of the working solution break down, which, being charged with the opposite sign, rush to the surface

electrified material, providing it with a continuous microlayer irrigation of the working solution that conducts electric current.

A stable inflow of the working solution from the tank 2 to the electrodes 5 of the dielectric material is sufficient for continuous irrigation with the working solution of the material being processed,

is provided with an electric current between the tank 2 and the grounded electrode 6.

Continuous irrigation of the material being processed by microdroplets of a conductive worker

solution provides direct neutralization of charges of static electricity in the zone of action of the neutralizer and creates the effect

antistatic treatment of the material, which remains in time until the solution film evaporates. Presence of dielectric body and tank for working solution

allows to significantly reduce the effect of ambient temperature and humidity, increase the operating time without recharging and increase the neutralization efficiency.
