Description

Mixing condenser, in which the cooling water by means of an in the amount of Distribution device arranged at the entry point is distributed in the case of mixing condensers it is known that the cooling water through a arranged at the level of the entry point To distribute annular overflow bowl, over the inner wheel of the cooling water like a veil falls down.

This arrangement has the disadvantage that the capacitor is a relatively must have a large diameter in order not to let the water veil become so thick, that its resistance to the passage of steam becomes too great.

It is therefore, in order to get by with a smaller diameter of the capacitor, the cooling water also already through a distributor device arranged at the level of the entry point so distributed that it flows downwards in several concentric ring veils.

For this purpose, concentric ring nozzles were used until now the entry point of the cooling water at one and the same height in the condenser are.

These ring nozzles have the advantage that they make it easy to remove the water veils to give a certain unchangeable strength and to distribute it very favorably design. In addition, the supply of the water to the nozzles is easy as well these can be attached to a common annular water chamber. on the other hand but the ring nozzles have the major disadvantage that they clog easily and Cause operational malfunctions that are difficult to eliminate. The invention has the purpose of distributing the water at the point of entry in several concentric To enable veils while avoiding the ring nozzles.

After it is known per se in the case of mixing capacitors, to the formation To use ring-shaped water veil overflow bowls, it made sense to use several of these Arrange bowls concentrically at the point of entry of the water at the same height.

But this does not give a favorable water distribution, because the inner Veils of water and especially the innermost become too strong and the passage of Oppose steam and air too much. The innermost veil would also become almost ineffective. The veils of water flowing over the inner edge of the bowls namely form a downward tapering cone envelope, and with great strength of the innermost veil would, with the small diameter of the innermost shell, be the The point of the cone come to lie very high, so only a mantle of very low height can form, while underneath the water would form an ineffective column. In addition, the water supply to the individual bowls is cumbersome.

These difficulties are overcome by the invention; same is that at the cooling water entry point concentric, like communicating pipes arranged interconnected overflow trays are, their inner overflow edges in different steps increasing from the outside to the inside Height.

It is achieved by the fact that on the outside large, further inwards, smaller ones distributed over the smaller circumference and all the way inside the smallest amounts of water distributed over the smallest ring, measured in this way it can be that the veil decreases from the outside to the inside Yield strength.

The outer water veil can be used again in the same way be subdivided by placing them in annular overflow bowls in a manner known per se Auffärigf-and the overflow edges of the bowls are correspondingly different altitudes.

In the drawing, an embodiment of the invention is in the vertical Center section through the mixing condenser shown.

The steam is introduced into the cylindrical condenser vessel a at the side at b, while the cooling water is supplied at the top at c and the venting device is connected at d. After entering the housing, the cooling water is distributed in three concentric, ring-shaped overflow bowls g, la, i with internal overflow edge k, L, w , connected at the bottom by pipelines e, f in the manner of communicating tubes. The overflow edges k, 1 , in lie at a height that increases in steps from the outside inwards, so that the outermost edge k is the deepest. The height of the overflow edges is calculated in such a way that outside the largest amounts of water are distributed on the largest circumference, further inward smaller amounts on smaller circumference and inside the smallest amounts on the smallest circumference in such a way that water veils decrease from smaller to decreasing from outside to inside Build strength.

The water that falls from the spill bowl 1c surrounding the innermost shell i is absorbed, according to the example shown, by a deep spill bowl n, which allows the water to overflow at the outer and inner edge, but whose outer spill edge o. Is again lower than the inner, P. The height of the edges is such that the water flowing off over the inner edge P falls down the container a in a veil that is somewhat thicker than the innermost, while the water falling over the outer edge o thicker stratification in a further, even deeper lying panic q is added. This also absorbs the water flowing out of the outermost pan. The outer overflow edge Y of this shell q is again lower than ', the inner edge s; and while the water falling from the latter falls back into the container ca with an even thicker veil than the two previously mentioned, the water falling from the outer edge v pours again into a lower lying panic t with an inner overflow edge u. At this point it forms Water falling into the container a creates the thickest veil, but it is easy to distribute the amount of water in such a way that here too there is no inadequate resistance to the steam passing through.

On the inner bottom edge of the bottom pan there is also a the outer water veil surrounding the sieve jacket v connected, which has a uniform Distribution of the steam induces and prevents the same at the point of entry comes into effect abruptly on the water veil.

Claims (1)

PATENT CLAIMS: I. Mixing condenser in which the cooling water is distributed by means of a distributor device arranged at the level of the entry point in such a way that it falls down in several concentric ring veils through which the steam or the steam-air mixture extracted during the venting can pass, thereby that the distribution device consists of concentrically arranged, ring-shaped overflow shells (g, la, i) connected to one another in the manner of communicating tubes, the overflow edges (k, 1, in) of which are at a height that increases gradually from the outside to the inside is dimensioned so that water veils are formed from a small thickness from the outside to the inside that gradually decreases in strength. 2. Mixing condenser according to claim z, characterized in that the ZVasserschleier surrounding the inner @ A-'asserschleier greater thickness of raiding shells (iz, q, t) are received, which are arranged in gradually decreasing height from the inside to the outside and their overflow edges (o, P or r, s and it) are also arranged at different heights so that the partial water veils that are formed also have a thickness that decreases from the outside inwards.
