description Re .; Device for cooling water vapor

Water vapor is used, inter alia. by injecting water on one brought lower temperature. That can be both in a special way built-in cooler (Fig. 1) or in a reducing station that simultaneously lowers the vapor pressure (Fig. 2), The steam enters the cooler at 1 in Fig. 1 and water is fed to it via a feed line (2), which is fed through a Annular gap (3) enters the steam space and see with the Steam is mixed or evaporated by this.

In Figure 2, the steam also enters the reducing station at 1, and the water is fed through the inlet (2) the annular gap (3), where it is also absorbed by the steam •.

Such facilities have the disadvantage that the moment the barrel injection at 2 does not "coincide with ~ the arrival of the first steam at 3. Rather, uncooled steam at 4 becomes both the cooler and the reducing station and only at a distance of several meters on one in the pipeline Meet heat sensor. This heat sensor registers the excessively high temperature of the steam and sends the corresponding information Relay a command to the actuating gear of the water injector that feeds the feed (2).

Between the impact of the steam on the heat sensor and the resulting injection of the cooling water at 3 a certain time elapses while the uncooled steam continues to flow in the pipeline. That steam hits on the steam consumer, for example a turbine, then because of the temperature that is too high. Shock effects occur that cause damage.

So a way has to be found to get around the first To add steam volume of water - to cool it. It must so - in other words - the short period of time between. Steam supply and injection of water bridged will. Experience has shown that this "is a few seconds. The necessary to bridge this time The amount of water can be determined precisely and is relatively small. It fluctuates depending on the size of the amount of steam and the temperature gradient is practically between 5 - 10 liters.

According to the invention, an additional water reservoir (5) is now arranged for this bridging, which Via lines (6) and (7) on the one hand with the steam room, on the other hand in connection with the water supply room stands. If steam now enters the cooler or the -Eed-uziersta-teon-at (l), then- arises -in the -Eaum between (1) and (3) an overpressure that is so great that that it propagates through the line (6) to the container (5). The water in it is over the line (7) is fed to the injection gap in Figure 1 or the injection gap (8) in Figure 2. See it here will be short distances and the pressure wave propagates extremely quickly, at the beginning of the steam overflow at 3 or 8 the Water from the container 5 supplied to the steam, so. that cooling is achieved immediately here. Kick it If there are temperature fluctuations, these are not particularly large and are immediately detected by the heat sensor Injector control gear forwarded and corrected.

To regulate the amount of water injected to a certain extent To enable either a diaphragm or a loading valve can be installed at 9 to prevent that too much water added to the steam at the first pressure surge

will. So you have it in your hand, the facility denotes to adapt to local conditions.

The water tank will always remain full because of the time differences between steam supply and water supply there is also between steam shut-off and water shut-off. So, while the steam is already shut off, a certain amount of time will pass during the Water is supplied .. Because the container is below the cooler or the reducing station is located, that which is subsequently supplied collects in it. Water and stays received there until the next commissioning of the devices.

Claims (1)

Expectations Claim 1 ". Steam cooler or reducing station for water injection, characterized in that it is an additional device obtained from a water tank and a pipe. system exists, such that the pipe feed is connected on the one hand in front of the injection point and on the other hand to the injection point itself. Claim 2 , characterized in that a diaphragm or a needle valve regulates the amount of water in the pipeline takes over.
