SU4794A1 - Surface steam cooler on ships - Google Patents

Description

For marine and river steam vessels, a pair of chillers is available on the outside of the hull below the waterline.

In FIG. 1 shows a diagram of the appearance of the hull of a ship with a coolant; FIG. 2 is a sectional diagram of a vessel with a coolant; FIG. 3- vessel hull with connecting grooves; FIG. 4, 5, b, 1-scheme options for the device.

On the underwater part of the metal hull of the vessel, corrugated metal lining of the B VI G (Fig. 1 and 2), solid (Fig. 1), or consisting of separate chambers I (Fig. 4) are fixed. For the passage of steam between the horizontal wavy ribs of the lining 5 and G, vertical transverse grooves D (Fig. 3) are squeezed out in the vessel hull, along which steam passes from the upper chambers of the lining to their lower chambers 3, where condensate accumulates and where it comes from

back inside the vessel for the desired purpose (Fig. 4), for example, for a conventional device refrigerator, to replenish the water consumed when feeding steam boilers. Instead of grooves D (Fig. 3), for the passage of steam, extruded in the metal hull of the vessel, patch metal sheets A with vertical ribs 5 (Fig. 5) may be arranged, held under the wavy lining C-D with the pipe D (Fig. 6). In the case of additional cooling sections G, F-, etc., the latter are connected to the main section G by means of the flanges of the upper nozzles 3 and the lower 3 (fig. 7).

The subject of the patent.

1. Surface cooler of that pair on ships, characterized by the use of metal undulating plates C and D (Fig. 1), mounted on the underwater part.

the metal hull of the vessel, separate chambers, And which lining are connected by grooves D, extruded ONE, on the hull of the vessel under HaRnajbikaMH, Vi. G, and worn. Dai enters the upper chamber of the Freshener, and the condensation water accumulates in the lower chamber 3, from where it flows back into the interior. the vessel and can be supplied to the internal refrigerator of a conventional device - to replenish water consumed in it for heating to power the steam boiler. 2. Modification of the surface | chiller m .pair on ships |

characterized in paragraph 1, characterized by replacing the grooves extruded on the ship hull with overlaid metal sheets A (Fig. 5) with ribs B arranged in vertical planes, on which sheets wavy lining B-D are placed. 3. Modification of the surface cooler, described in paragraph 2, characterized by the use of, in addition to the main cooler M (Fig. 7), the additional cooling sections W and W, connected to the main one by means of flanges of the right nozzles 3 and bottom

lfg one.
