Description

The invention relates to a technique for protection against harmful manifestations of static electricity. And can be used in the manufacture of filters for the purification of dielectric liquids (for example, hydrocarbon fuels).

A device for filtering dielectric fluids / containing housing with inlet and outlet is known. At least one filter package with inlet and outlet holes installed inside the device case, in which the filter package case is made of conductive material and isolated from the device case, and the input and output hole in the filter package case are coaxial, and the filter input package hole is attached. to the inlet nozzle of the device, and the outlet nozzles of the device are located on the housing on the same side as the inlet nozzle ij.

The disadvantage of this device is the low efficiency of neutralization, which is manifested in incomplete quenching of static electricity charges inside it due to the removal of extreme liquid streams carrying static electricity charges of a certain sign, from the body of the filter package, on the surface of which dy opposite sign.

The purpose of the invention is to increase the efficiency of neutralization of static electricity charges.

The goal is achieved by a device for filtering dielectric liquids, comprising a housing with inlet and outlet nozzles and at least one filter bag with inlet and outlet holes, installed inside the device body, in which the filter bag is made of conductive material and is isolated from the device’s housing, and the inlet and outlet openings in the filter-housing package are coaxial, while the inlet port of the filter package is attached to the device’s inlet Nozzle, and the device’s output nozzles are located on the housing on the same side as the inlet, provided with conductive filaments, installed parallel to the axis of the filter package between the device case and the filter package and electrically connected to the filter package.

The drawing shows the structural diagram of the device.

The device consists of a housing 1, an inlet 2, a housing 3 of the filter package, with an inlet 4, a filter package. filter elements 5 and OUTPUT hole 6, the dielectric insert 7, the upper and lower disks 8 of the keratrop filter housing, conductive filaments 9, output nozzles 10.

 Between the bottom of the device case and the filter package case there is a cavity 11, and between the side surface of the device case, the upper and lower disks of the filter package case, and the side, part of the filter package case, there is a cavity 12. In the lower disk of the filter package case, the perforation channels 13 are located. - Channels 14.

The device works as follows.

The dielectric fluid enters the device body 1 through the inlet 2 and then passes into the filter package body 3 through the filter package housing inlet 4. When passing through the filter barriers (fil svroelementy 5) of the filter package, it is cleared of mechanical impurities and, having acquired static electricity, of a certain sign, through the outlet 6 of the filter package body enters the cavity 1

In the process of filtering a liquid, the elements of the filter package acquire static electricity charges of the opposite sign of the charges in the liquid, which are distributed according to the well-known Ostrogradsky Gauss on the outer surface of the filter package 3, insulated from the device 1 with a dielectric insert 7, and also on the surface of the upper and lower disks 8, conductive filaments 9, tensioned between the disks.

With the passage of the fluid flow through the cavity 12, neutralization of the electrostatic charges in the fluid flow and charges of opposite sign, distributed on the outer surface of the filter package 3, occurs.

The additional placement of conductive filaments 9 in the cavity 12 improves the conditions for neutralizing the charges, since the charges of static electricity from the filter bag housing 3 are distributed on the surface of the disks and threads, therefore an electrostatic field is created in the cavity 12, contributing to the acceleration of liquid molecule associations. From the cavity 12. the fluid through the channels 14 in the upper disk enters the outlet nozzles 10 of the device.

So, with the volume of ambient electric charges in a flow of pumping volume up to 20 l / min, electric fluids 5, the cue potential of the fluid at the exit is the rate of their transportation with the prototype of the proposed implementation of technological processes for filtering liquids , improve fuel efficiency
