DISTILLER UTILIZING MECHANICAL VIBRATION

Japanese Patent JP3229742

B2

PURPOSE: To enhance the heat transfer efficiency of a heat transfer pipe, in a distiller wherein the heat transfer pipe is inserted in the bottom part of a column, by arranging a wire transmitting mechanical vibration in the vicinity of the heat transfer pipe and applying mechanical vibration to the liquid present in the bottom part of the column to prevent the adhesion of scale to the heat transfer pipe.
CONSTITUTION: In a distiller wherein a heat transfer pipe 3 is inserted in the bottom part of a column, a wire 7 transmitting mechanical vibration is arranged in the vicinity of the heat transfer pipe 3 and the contact surface of the heat transfer pipe 3 with the liquid present in the bottom part of the column is vibrated. The wire 7 transmitting mechanical vibration is pref. composed of a piano wire or a coil wire low in the coefficient of thermal expansion and excellent in durability. Vibration is applied to the wire by attaching the wire to an oscillator under tension. By this constitution, in the case of a liquid containing low, medium and high b.p. components and easy to generate scaling on the heat transfer pipe during distillation, the recovery efficiency of the medium b.p. component being a product is enhanced and the heat efficiency of the heat transfer pipe can be enhanced and the number of times of the cleaning of the heat transfer pipe can be reduced.
