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: poor-quality preparation of fuel for combustion at the maximum throughput of the device and limited service life.

The technical result is to improve the quality of preparation of fuel for combustion and increase the life of the device.

The technical result is achieved by the fact that at the bottom of the casing a sump made of non-magnetic material is fixed, having the shape of a funnel facing down a narrow part. The inlet fitting is placed in the cover along the axis of the housing. A nozzle for discharging contaminants is installed along the axis of the sump, and its upper end is placed at the level of the bottom of the casing. The outlet pipe is located at the bottom of the housing, and in the annular gap between the filter element and the magnets, a plate of non-magnetic material made in the form of a truncated cone is fixed to the bottom of the housing parallel to the inner surface of the magnets, and its upper edge is located at a distance of 0.15 from the cover. ..0.25 hull height.

The figure shows a 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 to the upper part, an inlet fitting with a threaded slot 5, the outlet pipe 6, located tangentially to the housing 1 at its bottom, and the pipe for the discharge of contaminants 7 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. The nozzle for discharging contaminants 7 is installed along the axis of the sump 8, and the upper end of the nozzle for discharging contaminants 7 is located at the bottom of the housing 1. The nozzle for discharging contaminants 7 is equipped with a valve 9. B an annular gap between the filter element 3 and the magnets 4 parallel to their inner surface on the bottom of the housing 1 is fixed to a plate 10 of non-magnetic material made in the form of a truncated cone, and its upper edge is located from the cover at a distance equal to 0.15 ... 0, 25 housing heights 1.

The device operates as follows.

Fuel through the inlet fitting with a threaded slot 5 is fed into the housing 1, and the fuel flow passing through the threaded slot acquires a rotational movement, distributed among the fractions. Such a distribution is facilitated by 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 6, located tangentially to the housing 1 at its bottom. 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. Then it passes along the annular gap between the plate 10 and the inner surface of the magnet 4. At the same time, it is further modified, after which it is brought out through the outlet pipe 6 located tangentially to the housing 1 at its bottom.

The location of the upper edge of the plate 10 from the lid 2 at a distance equal to 0.15 ... 0.25 of the height of the housing 1, improves the quality of fuel modification, including at maximum throughput of the device.

The contaminants present in the fuel accumulate in the sump 8. Periodically, the contaminants are removed from the sump 8 through the valve 9.

Improving the quality of fuel cleaning is achieved by removing contaminants from the cleaning zone into the sump and additional modification of the fuel when it passes in a narrow space between the plate and the magnet.

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 process.
