AIR CONDENSER

摘要

Air condenser for condensing vapors where freezing or solidification of the condensate is likely to occur. Finned tube bundles are used, which are arranged so as to form a primary condensation zone and a secondary condensation zone. The tube bundles are placed at a slope and are struck by an air stream coming from below. The innermost tubes are directly struck by the cooling airstream and make up the first condensation zone. The outermost tubes receive air which has been preheated since it has flowed through the first condensation zone. These outermost tubes make up the second condensation zone. Thus vapors which were not condensed immediately are condensed in the second condensation zone. The apparatus is a compact, self-contained and efficient unit which is cheaper than the prior art devices both as to initial cost and upkeep cost.
