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 nozzle for discharging contaminants is installed along the axis of the settler, and the upper end of the nozzle for discharging contaminants is placed at the bottom of the settler and is equipped with a crane. Starting from the annular gap, between the lower part of the filter element and the upper part of the sump, there is an ultrasonic hemispherical ring emitter for mechanical cleaning of the filter element.

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 precipitate 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 conical, the smaller base of which is turned up. In the inner cavity of the housing coaxially install a metal mesh of fine fuel. The filter element is located between the housing and the metal mesh for fine fuel cleaning. The magnet is made in the form of an electromagnetic coil and is installed on the outside of the case, with an increasing diameter of the turns in the direction from the bottom of the case to the upper part.

Figure 1 shows a longitudinal section of an electrostatic precipitator.

The electrostatic precipitator contains a conical body 1, the smaller base of which is facing up, a cover 2, a filter element 3 in the form of a truncated cone expanding downward from a conductive material, a magnet 4. Magnet 4 is made in the form of an electromagnetic coil and is installed on the outside of the case with an increasing diameter of turns in direction from the bottom of the case to the top. On the outside of the magnet 4 is installed a protective casing 5. In the upper part of the cover 2 there is an inlet fitting 6 with a threaded slot. On a tangent to the housing 1, in its lower part, an outlet pipe 7 is installed for fuel output. In the inner cavity of the housing 1 coaxially mounted metal mesh 8 fine fuel. The filter element 3 is located between the housing 1 and the metal mesh 8 of the fine fuel. At the bottom of the housing 1, a settler 9 made of non-magnetic material is fixed, having the shape of a funnel with a narrow part facing down. Under the sump 9, an outlet pipe 10 is installed to discharge contaminants. In the outlet pipe 10 for the discharge of impurities a bypass valve (or valve) 11 is installed.

Between the lower part of the filter element 3 and the upper part of the sump 9, there is an ultrasonic hemispherical annular emitter 12 for mechanical self-cleaning of the filter element 3 and the metal mesh 8.

The device operates as follows.

Fuel through the inlet fitting 6 with a threaded slot enters the housing 1. Moreover, the fuel flow passing through the threaded slot of the inlet 6 acquires a rotational movement, distributed among the fractions. This distribution contributes to a decrease in the speed of fuel movement by 3 ... 4 times due to the expansion of its flow in the conical internal cavity of the device. The process of rotational motion is supported by the outlet pipe 7, 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 output to the opposite.

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: at the inlet it is greater than at the outlet. Fuel, passing through a metal mesh 8 of fine fuel and filter element 3, is cleaned, modified by an electromagnetic field, and then through the outlet pipe 7 is brought out. The contaminants present in the fuel accumulate in the sump 9 and, as they accumulate, are removed from the sump through the valve 11. The upper end of the pipe 10 for dumping pollution is placed at the bottom of the sump 9.

Improving the quality of fuel cleaning is achieved by additional cleaning of the filter element 3, paraffins deposited on it, an ultrasonic emitter 12.

The execution of the body is conical, the smaller base of which is facing up, as well as the presence of a magnet in the form of an electromagnetic coil on the outside of the body with an increasing diameter of turns in the direction from the bottom of the body to the top, allows you to set the intensity of the electromagnetic field at the fuel inlet to the body more than at the output .

The installation in the inner cavity of the body of a coaxial metal mesh of fine fuel and filter element 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, and the contaminants accumulating in the sump are removed as necessary without interrupting the operation.

The invention improves the quality of fuel cleaning due to ultrasonic mechanical cleaning of the filter element and improve the conditions for the deposition of contaminants.
