    摘要： A plate-type condenser comprises a row of spaced-apart heat transfer plates defining an alternating series of gaseous passages and cooling liquid passages. Within each gaseous passage is provided a plurality of liquid-collecting means for directing the condensed liquid vertically downwardly along discrete flow passages thereby minimizing contact between the heat transfer plates and the condensed liquid. The liquid-collecting means comprises either an array of inclined projections or recesses formed within the heat transfer plates.

    摘要： 1,212,252. Surface condensers. SALINE WATER CONVERSION CORP. 20 Feb., 1968 [21 Feb., 1967], No. 8118/68. Heading F2S. [Also in Division B1] A surface condenser intended for use in a desalination plant comprises a chamber through which horizontal tubes extend and on the outside of which tubes a vapour is condensed by a coolant flowing through the tubes, said tubes occupying a volume in the range of 2 to 5% of the total volume of said chamber, and being so arranged that condensate from any one tube falls into a collecting trough thereunder without contacting any other tube. In Fig. 3, a pool 54 of saline water is maintained in a housing 52 and further saline water at a slightly higher pressure is injected into the pool via a tube 50. Some of the injected water flashes into steam on the surface of the pool, whereafter condensation takes place on the surface of the coolant tubes 60a, 60b, 60c, the condensate being collected in troughs 58. Fig. 5 (and Fig. 6) shows part of a multistage flash evaporator and surface condenser, two stages being shown. Each condenser stage includes tubes 112 or 112 1 grouped in sheet metal condensate collecting troughs 104 or 104 1 . Above the open end of each trough is a canopy 110 or 110 1 which prevents impingement on the condenser tubes of unevaporated saline water droplets from the preceding stage. These droplets are diverted by the canopy on to the outer surface of the associated trough 104 or 104 1 whence they flow through passageways 106 or 106 1 between adjacent troughs to a collector tray 120 or 120 1 therebeneath. From each tray are passages 122 or 122 1 packed with a permeable material and in which flash evaporation occurs, the resulting vapour passing to the next lower condenser stage of the system. A further form of combined flash evaporator and surface condenser is described (Fig. 1) in which the condenser tubes are in groups one above the other, separated by a drip deflector baffle (34). In another condenser arrangement described (Fig. 4) a cylindrical shell is divided by transverse partitions (72, 74) into a vapour inlet chamber in communication with two other chambers (78, 79) each containing a set of condenser tubes (80). This arrangement is apparently intended for comparing condenser tubes having different positional arrangements and surface characteristics; e.g. the tubes (80) in one chamber may be made of titanium whilst those in the other chamber may be of a cupro-nickel composition.
