Description

The invention relates to devices for purifying liquids, in particular for refining petroleum products.

A centrifugal cleaner is known, consisting of a housing, a rotor, a nozzle, an oil discharge tube, a rotor core, an oil deflector, nozzles and a rotor cover.

The disadvantage of this cleaner is the complexity of maintenance, the complexity of the design, the unregulated speed of the oil in the rotor, which contributes to the removal of contaminants.

. A device for cleaning liquids is also known, consisting of a housing, a hopper with a drain plug for removing sediment, a cover with nozzles for introducing liquid and output of the filtrate, in which a hollow perforated rotor with a filter element attached to it is mounted on the bearings. The device is equipped with regeneration means made in the form of two guide vanes fixedly mounted outside and inside the filter element.

The disadvantage of this filter is the need for an extraneous energy-intensive drive to rotate the rotor and the insufficient regeneration of the filter surface.

The purpose of the invention is to reduce labor costs for maintenance of the filter, increase the efficiency of regeneration of the filter surface, ensure the continuity of operation of the device while removing contaminants from the hopper, and reduce environmentally harmful substances emitted during maintenance of the device.

This goal is achieved by the fact that the filter element is mounted in an additional housing with the possibility of rotation relative to the hollow axis, while the hollow axis is made in two sections, the additional housing is equipped with nozzles, and the hopper is equipped with a drain device interconnected with the hollow axis, inlet and outlet nozzles and a package of conical plates moreover, check valves are installed on the upper conical plate: -

Placing the filter element in an intermediate housing equipped with jet nozzles allows, at the same time as creating a hydrodynamic effect due to the rotation of the filter element, to create a constant longitudinal fluid flow along the surface of the filter element, increasing the regeneration effect of the indicated surface, and to automatically adjust the frequency of rotation of the filter element depending on the degree of pollution of the filter surface . The presence of a package of plates in the hopper provides a preliminary cleaning of the liquid entering the hopper through the nozzle holes before it is again fed into the device body, and the presence of check valves in the upper conical plate ensures the continuity of operation of the device during discharge of sludge from the hopper and reduces the amount of environmentally harmful drain waste .

Thus, the device has a new property - self-regulation of the rotor speed depending on the degree of contamination of the liquid and the pressure drop across the filter surface.

Only with this combination of features can the object of the invention be achieved.

The drawing shows a device for cleaning liquids.

A device for cleaning liquids includes a housing 1, a hopper 2 with a drain device 3, which has openings 4,5,6; inlet pipe 7, outlet pipe 3, cover 9 with fluid inlet and filtrate outlet pipes 11, in which the axis 12 is rigidly mounted with holes 13,14,15,16, 17,18 and 19, on which are mounted on bearings 20 and 21 a sleeve 22 with holes 23, a bottom 24 of the safety chamber 24 with nozzles 26, a safety chamber 25 and a filter element 27 installed inside the safety chamber 25.

In order to increase the settling efficiency of the liquid contained in the hopper 2,

the device is equipped with a package of conical plates 28.

To ensure continuous operation of the device during discharge from the hopper 2 and to reduce the amount of liquid to be drained, the upper conical plate 29 is sealed relative to the walls of the hopper 2 and the surface of the hollow axis 12, and normally open non-return valves 30 are installed on the surface of the upper conical plate 29. - bushing 31 with holes 32 is installed in a row with the drain device.

A device for cleaning liquids operates as follows.

The cleaned liquid enters through the inlet pipe 7 into the space between

the lower bottom 24 of the chamber 25 and the upper conical plate 29 and exits through the beneficial pipe 8. Next, the liquid, passing through the pump, (see figure 1), the inlet pipe 10, holes 13, 14 and 23 enters the space between the camera 25 and the filter - cop 27.

The main part of the liquid, the passage through the filter element 27, is cleaned and discharged through the outlet pipe 11.

The rest of the liquid, flowing out at high speed through the nozzle holes of the reactive forces 26, creates a torque leading to the rotational movement of the chamber 25 together with the filter element

27. Then, the liquid flowing through the nozzle openings of the nozzles 26, passing through the holes 17, 5 and 19, enters the lower part of the hopper 2, passes between the plates 28, where it is cleaned by dynamic settling, exits through the normally open non-return valves 30 and mixes with the cleaned the liquid entering through the inlet pipe 7 and again goes to the cleaning.

In case of clogging of the filter surface of the filter element 27 with contaminants, the amount of liquid passing through this surface decreases, and, accordingly, the longitudinal flow of fluid entering the nozzles 26 increases. In this case, the conditions for self-regeneration of the filter element 27 are improved due to the simultaneous action of two factors: flushing intensification knowledge by longitudinal flow and

increasing the speed of the filter element.

To drain the sludge from the hopper by rotating the drainage device 3, the holes 5 are moved relative to the holes 19 and the passage of liquid through these holes is stopped, and the holes 4 are aligned with the holes 18, while the liquid flowing out of the nozzle holes through the holes 4, 18 and the outlet pipe 8 again flows into the pump (see drawing). Holes 6 and 31 are aligned with each other and sludge is drained through these holes. In this case, the non-return valves 30 are closed and, together with the sludge, only the liquid located under the upper conical plate 29 is removed from the hopper 2.

The use of the proposed device for cleaning liquids can reduce the duration of its maintenance, reduce energy consumption and reduce the amount of emitted environmentally harmful substances.
