Description

The utility model relates to devices for cleaning liquid fuel and preparing it for combustion.

A device for cleaning and preparing liquid fuel for combustion [A device for cleaning and preparing liquid fuel for combustion. Patent RU No. 2407951. - Publ. 12/27/2010, Bull. No. 36], including a filter element located in a housing provided with a cover in the form of a truncated cone expanding downward. Magnet in the form of a coil having the shape of a truncated cone, expanding to the upper part, an inlet fitting with a threaded slot, a nozzle for the fuel outlet, which is located tangentially to the body at its bottom. At the bottom of the casing, a sump made of non-magnetic material and having the shape of a funnel facing down a narrow part is fixed. The inlet fitting is located in the upper part of the cover along the axis of the housing. The pipe for the discharge of pollution is installed along the axis of the sump, and the upper end of the pipe for discharge of pollution is placed at the bottom of the sump and is equipped with a crane.

However, this device has the following disadvantages: in the cold season, isoparaffins and naphthenes contained in diesel fuel, having lower cetane numbers and not having an ionic structure, i.e. charge neutral, coagulate and settle on the filter element, reducing its throughput. With decreasing throughput of the filtering element, poor-quality preparation of fuel for combustion occurs, while the resource of the device is reduced.

The purpose of the utility model is to improve the quality of cleaning and preparation of fuel for combustion.

This goal is achieved by the fact that the body is cylindrical. The cover is removable and placed in the upper cylindrical part of the housing. The inlet fitting is installed tangentially to the cylindrical part of the housing in its upper part. On the opposite side of the casing, in its lower conical part, an outlet pipe is tangentially installed to withdraw purified fuel. The magnet is made in the form of an electromagnetic coil and is installed on the outside of the housing. The filter element contains metal grids of coarse and fine fuel and filtering non-magnetic material.

Figure 1 shows a longitudinal section of an electrostatic precipitator.

The electrostatic precipitator includes a housing 1 made cylindrical, a cover 2, a filter element 3, a magnet 4. The cover 2 is removable and located in the upper cylindrical part of the housing 1. The magnet 4 is made in the form of an electromagnetic coil and is installed on the outside of the housing. On the outside of the magnet 4 is installed a protective casing 5. The inlet 6 is installed tangentially to the cylindrical part of the housing 1 in its upper part. On the opposite side of the housing 1, in its lower conical part, an outlet pipe 7 is tangentially mounted for outputting purified fuel. The filter element 3 is located in the inner cavity of the housing 1 and contains metal grids of coarse 8 and fine fuel 9 and filtering non-magnetic material 10. Filter non-magnetic material 10 is located between the metal grids of rough 8 and fine 9 fuel. At the bottom of the housing 1, a settling tank 11 made of non-magnetic material is fixed, having the shape of a funnel, and facing down with a narrow part. Under the sump 11, an outlet 12 is installed to discharge contaminants. In the outlet pipe 12 for the discharge of impurities a bypass valve (or tap) 13 is installed.

The electrostatic precipitator works as follows.

Fuel through the inlet 6 enters the housing 1. The flow of fuel passing through the inlet 6, acquires a rotational movement in the housing 1, between the internal cavity of the housing 1 and the filter element 3. In this case, metallic impurities (as a rule, metal dust generated in the process wear of the cylinder-piston group) is delayed by a metal screen 8 of coarse fuel, and smaller ones by a metal screen 9 of fine fuel and, accordingly, filtering non-magnetic material 10. The process of rotational movement under held by the outlet pipe 7 for output of purified fuel, located tangentially to the housing 1 in its lower part. In this case, the direction of the rotational motion of the fuel changes at the exit to the opposite movement.

At the same time, the fuel is exposed to the electromagnetic field created by the magnet 4, made in the form of an electromagnetic coil, the intensity of which is not the same throughout the cleaning zone. Fuel passing through the filter element 3 is cleaned, modified by the electromagnetic field created by the magnet 4, and then through the outlet pipe 7 is displayed outside. The contaminants present in the fuel accumulate in the sump 11 and, as they accumulate, are removed from the sump 11 through the valve 13. The upper end of the pipe 12 for dumping pollution is placed at the bottom of the sump 11.

The execution of the housing 1 is cylindrical, as well as the presence of magnet 4 in the form of an electromagnetic coil on the outside of the housing, allows you to set the intensity of the electromagnetic field at the fuel inlet to the housing more than at the output.

The installation of the filter element 3 in the inner cavity of the housing 1, containing metal grids of coarse 8 and fine 9 fuel cleaning and filtering non-magnetic material 10, allows you to clean the fuel not only from mechanical impurities, but also from paraffins present in the fuel.

The service life of the device increases due to the fact that a constant flow of purified fuel is provided through the filter element 3, and the contaminants accumulating in the sump 11 are removed from it as necessary without interrupting the operation.

The installation of the inlet fitting 6 of the tangentially cylindrical part of the housing 1 in its upper part allows for the rotation of the fuel with a thin layer of the wall in the inner cavity of the housing 1 from the cylindrical part of the housing 1 to its lower conical part.

The installation of the outlet pipe 7 for the output of purified fuel from the opposite side of the housing 1 tangentially to the housing 1, in its lower conical part, allows the fuel to change its direction at the outlet sharply, as a result of which the impurities remaining in the fuel precipitate sharply downward, and the fuel is removed from the housing 1 through outlet pipe 7.

The implementation of the cover 2 is removable and its location in the upper cylindrical part of the housing 1 can reduce labor costs when servicing the electrostatic precipitator.
