Description

Device for deflecting and separating from water or boiler pipes Steam-liquid mixtures escaping from steam boilers. The invention relates on a device for diverting and separating from 'water or boiling pipes Liquid mixtures escaping from steam boilers according to patent q.3o69i. She concerns a further improvement on the device shown in that patent.

In the drawing, the invention is for example on a field tube boiler illustrated, namely Fig. i shows a cross-section through such a boiler, Fig. 2 is a longitudinal section along line A-B of Fig. I, Fig. 3 is a section along the line C-D of Fig. I.

In the drawing are the field pipes inserted into an upper boiler c denoted by h. An inner feed pipe i is used for these pipes to be evaporated Liquid supplied. The vapor-liquid mixture generated rises in the pipe h on and must, so that a vapor that is as dry as possible is obtained, in its components be disassembled, as already described in the main patent. .

In the present case, the vapor liquid mixture flows after it is the throttle valve formed by a ball m, - its. Side openings n (Fig.3) also remain open in the final position of the ball, has happened, into the interior the deflection hood k. Another hood a is provided inside this hood k. The vapor-liquid mixture flows between these two hoods according to the arrow o to the level of the liquid contained in the upper boiler c and is used in the deflection centrifuged, d. H. the heavier liquid and those suspended in the vapor Liquid particles are pushed outwards, while the specifically lighter ones Steam stays on the inside of the curve. The separated steam then flows according to the arrow p through the annular space g and the openings b into the vapor space d of the Upper boiler. away. To guide the ball in are useful inside the hood a Guide ribs g provided.

Claims (1)

PATENT CLAIM: Device for deflecting and separating steam-liquid mixtures emerging from water or boiler pipes of steam boilers according to patent q.3o69i, characterized in that a second hood (a) is arranged in the deflection hood (k ) in such a way that in the space between the two Hoods the steam-liquid mixture is diverted to the liquid level in the upper boiler (c), whereby the vapor that collects inside the hood (k), which is led down to below the liquid level, through the pipe sockets (k, a) led through both hoods (k, a) f) is discharged into the upper boiler.
