Description

This invention relates to shipbuilding, in particular, to devices for receiving and cleaning seawater.

A device for receiving and cleaning seawater, containing a Kingston box with a receiving grid, communicated with an air outlet pipe, and a filtering element 1 installed therein is known.

However, the known device does not provide effective purification of water, stirred up by air bubbles with floatable or fine particles.

The purpose of the invention is to increase operational performance.

The goal is achieved by the fact that in the device for receiving and purifying seawater, containing a kingston box with a receiving grid, communicated with an air outlet pipe, and a filter element installed in it, the latter includes flooded granules, which are placed between the mesh air baffles, along at least two of which are set at an angle of 45-70 ° to the horizontal with a rise in the direction of the air exhaust pipe, and these partitions are made with bent half-hems, the mouth of which faces in the top, and the central angle of the limb of these half-faces is 15 ° smaller, the angle of inclination of the indicated partitions.

FIG. 1 schematically shows a device for receiving and cleaning seawater; in fig. 2 — node I in FIG. one; in fig. 3 - the shape of the holes in the partitions of the device in a perspective view.

The device for receiving and cleaning seawater consists of a kingston box 1 with a receiving grid 2, a kingston 3 and an air vent 4, a filter element 5 placed between the air baffles 6 and 7, installed at an angle of 45-70 ° to the horizontal with a rise to the side of the air vent pipes. The pre-treatment filter element 8 is bounded by a grid 9. The enclosure 10 has an air vent notch 11 and, together with the grid 12 and the walls of the kingston crate, forms an air collection nickname.

The half-faces 13 of the air vent partitions are squeezed out in the direction of the movement of water, forming slit-like holes 14. The pipe 15 is designed to supply regenerating water.

The filter element consists of filler granules 16, for example, of foamed

polystyrene. The angle of the limb semi-corrugated 13 is 15 ° less than the angle of inclination of the partitions 6 and 7. The device works as follows.

The seawater contaminated with floatable particles of soil and sludge passes through the receiving grid 2 and is filtered through partitions 6 and 7, filtering elements 5 and 8 and grid 9. Large air bubbles with a small amount of soil particles being floated have a specific weight that is less than the specific weight of the outboard water, which reaches the partition 6 with the water flow, begins to move upward toward the air 5 of the outlet pipe 4. Since the half-hems 13 are bent inward, the bubbles slide unhindered over the surface of the partition 6. Suspended particles and small air bubbles along with the flow of water pass

0 through the holes 14 and fall on the filter element 5. Suspended granules of foamed polystyrene 16, possessing coalescing properties, accumulate flotation particles in the water accumulated on their surfaces.

 Air bubbles released from the floatable particles are enlarged and, under the influence of lift, rush to the air exhaust pipe 4. The main part of the polluted seawater is cleaned in

Q filter element 5, and in element 8 there is an additional purification. The remaining air bubbles, the passage through the grid 9, leave the cavity of the kingston crate through the notches 11 to the air outlet pipe 4. Cleared out of suspended matter outboard water through the Kingston 3 is supplied to the needs of the craft. In the regeneration mode, the water purified in another similar device of the watercraft enters through the pipe 15 and is filtered through the elements of the device with a reverse current. The soil particles enlarged by coalescing granules 16 are washed overboard through the receiving grid 2.

The expected positive effect from the use of the present invention is to improve the operation of the ship

5 engines and mechanisms by providing better heat transfer and reduced wear. In addition, the invention will reduce the time costs associated with servicing the device itself by

Q simplicity of regeneration, as well as ship devices, whose operation is connected with the system of seawater.
