DOUBLE-CYLINDER HEATING TYPE MEMBRANE MODULE

摘要

PROBLEM TO BE SOLVED: To optimize a required membrane area by preventing reduction of a temperature of a fed liquid (liquid to be treated) in a module or condensation of a fed vapor (vapor to be treated). SOLUTION: The double-cylinder heating type membrane module is provided with a cylinder type body 14; a pipe plate 15 attached to an opening end of the body; and a channel 17 covering the pipe plate, closing the opening of the body and having a permeation vapor taking out port 16. In the membrane module, an opening end of a tubular separation membrane body 18 is attached to the pipe plate in the cantilever form. The tubular separation membrane body 18 is covered with a sleeve pipe 23 to form a double pipe shape and a heating medium b is fed into the body 14 to heat a mixture a fed into the sleeve pipe.
