Description

The invention relates to a device for cleaning liquid fuel and preparing it for combustion.

A device for cleaning and preparing liquid fuel for combustion [1], containing located in a housing provided with a cover, a filter element, magnets, as well as an inlet fitting and an outlet pipe mounted on the housing. The filter element of the device is made in the form of a truncated cone expanding downward, the wide part of which is equipped with a pipe for collecting impurities, having a threaded gap. The magnets are made in the form of a coil, which also has the shape of a truncated cone, expanding to the upper part, the inlet fitting is made with a threaded slot, and the outlet pipe is tangent to the housing.

However, this device has the following disadvantages: the impossibility of cleaning fuel from heavy metal ions, as well as a limited service life.

The technical result is to improve the quality of preparation of fuel for combustion by improving the degree of purification and increasing the life of the device.

The technical result is achieved by the fact that the bottom of the body is made of non-magnetic material in the form of a funnel, facing down a narrow part. At the bottom of the casing, a settling tank having the shape of a truncated, tapering down cone is fixed. The inlet fitting is placed in the upper part of the cover along the axis of the casing, and the nozzle for discharge of impurities is installed along the axis of the sump. The upper part of the pipe for the discharge of contaminants is placed at the bottom of the housing. The outlet pipe is located at the bottom of the housing. The filter element is made of conductive material. A spiral of conductive material is arranged on the outside of the nozzle to discharge the impurities, the filter element and the spiral being connected by electric wires to the terminals located on the outer surface of the housing.

The drawing shows a cross section of a device for cleaning and preparing liquid fuel for combustion.

A device for cleaning and preparing liquid fuel for combustion comprises a filter element 3 in the form of a truncated cone expanding downward, located in a housing 1 provided with a cover 2, and magnets in the form of a coil 4 having the shape of a truncated cone expanding toward the top, an inlet fitting 5 with a threaded slot, the outlet pipe 6, located tangentially to the housing 1, and the pipe 7 to discharge contaminants with a threaded gap. At the bottom of the housing 1, a sump 8 is fixed, made of a non-magnetic material and having the shape of a funnel facing down a narrow part. The inlet fitting 5 is placed in the upper part of the cover 2 along the axis of the housing 1. A pipe 7 for discharging contaminants is installed along the axis of the settler 8, and the upper part of the pipe 7 for discharging contaminants is placed at the bottom of the housing 1. The filter element 3 is made of conductive material. A spiral 9 of conductive material is located on the outside of the nozzle 7 for contaminant discharge, the filter element 3 and the spiral 9 being connected by electric wires 10 to the terminals 11 located on the outer surface of the device. The pipe 7 for discharging pollution is equipped with a valve 12.

The device operates as follows. Previously, the terminals 11 are connected to a direct current source so that the filter element 3 is connected to the positive pole of the current source, and the spiral 9 is connected to the negative. Coil 4 is also connected to a direct current source.

Fuel through the inlet fitting 5 with a threaded slot is fed into the housing 1, and the fuel flow passing through the threaded slot acquires a rotational movement, distributed among the fractions. This distribution is facilitated by the fact that, as it moves due to the expansion of the cone, the fuel speed decreases by 3 ... 4 times. The process of rotational motion is supported by the outlet pipe 6, 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 coil 4, the intensity of which is not the same throughout the cleaning zone: at the inlet it is 9.5 ... 10.5 times more than at the outlet.

Fuel passing through the filter element 3 is cleaned, and the heavy metal ions contained in it are deposited on the spiral 9. The contaminants present in the fuel accumulate in the sump 8. Periodically, the contaminants are removed from the sump 8 through the valve 12.

Improving the quality of fuel treatment is achieved by removing heavy metal ions from it, as well as removing contaminants from the treatment zone into the sump.

The service life of the device increases due to the fact that contaminants accumulate in the sump and can be removed as necessary, without interrupting the operation process and without exerting a negative effect on it.
