<p>PURPOSE:To produce a supersonic vibrator near each intake port of transfer pipes branching out of an air-liquid separator to each tank to produce air bubbles and reduce the apparent specific gravity of liquid in the transfer pipes for facilitating the unloading by compressor with small sucking capacity. CONSTITUTION:If a submerged pump 10A mounted on a tank 1A is disabled for unloading, a supersonic vibrator 15A is operated together with a compressor 3. Thus liquid within the tank 1A ascends in a transfer pipe 12A together with bubbles produced by evapolation, and liquid separated by an air-liquid separator 11 is transferred to a tank 1B and unloaded by a submerged pump of the tank 1B. On the othe hand, separated gas, after compressed by the compressor, is liquefied by a condenser 6 and transferred to the tank B through return pipes 8, 8B.</p> |
