Abstract

1,199,554. Moving gases hydraulically. ANGLO AMERICAN CORP. OF SOUTH AFRICA Ltd. Jan.29, 1969 [Feb. 2, 1968], No.4837/69. Heading F1N. [Also in Divisions B1-2] Apparatus for changing the temperature and moisture content of a gas comprises expansion and compression compartments 4, 5, each having an inlet valve 7 or 11 and an outlet valve 8 or 10 and each variable in volume by a reciprocating liquid piston 1. The reciprocation of the pistons may be effected by mechanically rocking the compartments or simply as a result of the sequentially occurring pressures in the compartments. The apparatus may perform either a heating or cooling cycle. To operate as an air heater and dehumidifier, the air for treatment is admitted to the expansion compartment 4 through the inlet valve 7. The valve 7 is closed by a spring 15 before the liquid piston 1 completes its downward stroke in the compartment 4. Hence the air is expanded and moisture is condensed before pressure responsive outlet valve 10 opens to admit the air to a vessel 9, possibly containing a heater. The condensate is removed through a flexible tube 29 leading through a float 3 situated above the liquid 1. From the vessel 9 the air enters the compression compartment 5, this transfer occurring during the downward stroke of its piston. Dryer and hotter air, but at substantially the original pressure, is then discharged from the compartment during the piston's upward stroke. To cool air a reverse operation is effected, and this mode of operation may additionally be used to evaporate a liquid for example in desalination of brine. Thus air enters through the valve 11 and is compressed in the compartment 5 in the presence of the brine injected into the compartment through a spray 26. The compressed air is transferred via a vessel 6 to the expansion compartment where the evaporated water is condensed. The concentrated brine is removed through a valve 27.
