PATENT OFFICE,

As is well known, attempts have been made to compress or Diluting gases through to effect a column of liquid, the latter in a pressure vessel by means of steam was controlled. This control was carried out in such a way that the space of the pressure vessel Above the level of the liquid column alternately with the steam line and with the external atmosphere in connection

ίο set so that the liquid was alternately pressed into the compression tank, in which the compression of the gas should take place, respectively. from the same flowed back into the pressure vessel. Here ^L

However, there was the disadvantage that as soon as a liquid was used as a barrier liquid of a tough consistency was compelled to use the flowing back of the same from the compression vessel to the pressure vessel connected to the external atmosphere proceeded very slowly. this Only a small part of it was due to the fact that the water flowing back into the pressure vessel Barrier fluid the friction on the vessel walls and the viscous Characteristics of the resulting resistance had to be overcome. That circumstance which mainly prevents the barrier liquid from flowing back into the pressure vessel in the The most unfavorable sense was the hydraulic, which was steadily decreasing to zero Pressure difference between the falling liquid level in the compression tank and the Rising of the liquid level in the pressure vessel. The same had just at barrier fluid of viscous nature means that the backflow of the barrier liquid from the compression vessel to the pressure vessel extended over a relatively long period of time, especially since the steadily growing column of liquid in the pressure vessel during the reflux creates a corresponding hydraulic counterpressure, exerted on the barrier liquid flowing back into the pressure vessel. Of course, this resulted in a proportional one slow work of gas compression and / or gas compression. Gasverdünmmgsvorrichtung so that the Performance of the same was a relatively low one.

The indicated disadvantage is avoided in this way in the present device been that the compression tank BEZW. the tube that holds the compression tank connects to the pressure vessel, a correspondingly smaller cross-section granted BEZW. the Compression tank is arranged higher than the pressure vessel. As a consequence, that the liquid column, which during the reflux of the barrier liquid from the Compression container is formed in the pressure vessel in the latter, with respect to the for Available significant hydraulic pressure difference between the two liquid

Claims (2)

energy mirrors in the vessels mentioned is almost out of the question and therefore also cannot noticeably delay the reflux of the barrier liquid. The main advantage of the present device is therefore that the Backflow of the sealing liquid from the compression vessel into the pressure vessel during the suction period takes place faster and therefore the performance of the device a larger than that of the previous gas compression or. Gas dilution devices is. The present device is shown in two different forms on the accompanying drawings Embodiments shown in sections and consists of the pressure vessel 1, the compression vessel 2 and the associated management organs. In the embodiment 1 is the compression container 2, which is correspondingly smaller Cross-section than the pressure vessel I has, inserted into the latter like a tube and extends to close to the bottom same approach. If the level of the sealing liquid is located, as shown in Fig. 1, in the compression vessel 2 in its deepest, in the pressure vessel 1, however, in its highest Position, the double float 5, 6 guided at 7 is lifted and the compressed air valve 8 is open, while the vent valve 9 is opened by means of the lever that can be rotated by 11 10 closed. The compressed air entering through nozzle 12 pushes the pressure in the pressure vessel located barrier liquid into the container 2, where the liquid level itself increases and thereby compresses the gas previously sucked in through line 13 respectively. is conveyed through the riser line 4 and pressure valve 3 into the pressure line 14. As soon as the liquid level is up to the lower edge of the lower float part 5 has fallen, the double float sinks down, closes the compressed air valve 8 and opens the vent valve 9, so that the compressed air present in the vessel 1 into the free atmosphere can escape and the sealing liquid from the compression tank 2 passes into the pressure vessel. Here is. the barrier liquid due to the large, due to the different cross-sections of the vessels 1 and 2, the distance two liquid levels from each other flow back relatively quickly into the pressure vessel and get into the earlier position marked in Fig. 1, whereupon the fresh gas is sucked from the suction chamber through line 13 and the game of begins again. In the embodiment according to FIG. 2, the new effect indicated above is thereby achieved achieved that not the compression vessel, but the pipe that connects the pressure vessel to the compression vessel connects, a correspondingly smaller cross-section than the pressure vessel BEZW. the compression tank granted and the latter is set higher than the pressure vessel at the same time. The drawing (Fig. 2) illustrates that moment in which the pressure vessel ι connected to the outside atmosphere by vent valve 9 and the sealing liquid in the compression container 2 has already partially passed through Management organs 16, 17 in the pressure vessel 1 has flowed back. As the reflux goes on, the level falls in the Vessel 2, on the other hand, rises in vessel 1 under the influence of a relatively significant hydraulic pressure difference increases quickly until it reaches the upper float part 6 and the double float 5, 6 is lifted. As a result, the vent valve 9 closed, but the compressed air medium valve 8 opened, whereupon the valve 8 entering pressure medium, the sealing liquid in the pressure vessel into the compression vessel 2 pushes in. In the latter, the fluid level rises again and compresses the gas previously sucked in through line 13 respectively. promotes the same through Climbing line 4 and pressure valve 3 in the pressure line 14. As soon as the liquid level fallen in the pressure vessel 1 up to the lower edge of the lower float part 5 is, the double float sinks down, closes the pressure medium valve 8 and opens the vent valve 9, so that the The compressed air present in the vessel 1 escapes into the free atmosphere and the barrier liquid as a result of the steadily decreasing but still significant hydraulic pressure difference between the liquid level in vessels 2 and 1 flow back into the pressure vessel can, whereupon the fresh gas is sucked out of the suction chamber through line 13 and the game starts all over again.
