Abstract
A reflux condenser and a method for conducting away liquid from the lower region of reflux passages, is disclosed. The reflux condenser has at least one heat exchanger block which has reflux passages and refrigerant passages, and a pressure container which encloses the heat exchanger block at the top and laterally. The reflux passages communicate at their lower end with a header which is arranged below the heat exchanger block and has a phase-separating device.
Claims23
A reflux condenser comprising a heat exchanger block which has reflux passages and refrigerant passages, a pressure container which encloses the heat exchanger block at a top and laterally, means for introducing steam into a lower region of the reflux passages, means for conducting away liquid from the lower region of the reflux passages, means for drawing steam out of an upper region of the reflux passages, and means for introducing refrigerant into the refrigerant passages, wherein the reflux passages communicate at a lower end thereof with a header which is arranged below the heat exchanger block and has a phase-separating device.
A reflux condenser, comprising:
- a heat exchanger block, wherein the heat exchanger block is enclosed by a pressure container;
- and
- a header with a phase-separating device arranged below the heat exchanger block, wherein the phase-separating device includes a base and wherein the base has a gas passage opening;
- and wherein a border surrounds the gas passage opening on an upper side of the base.
A reflux condenser, comprising:
- a heat exchanger block, wherein the heat exchanger block is enclosed by a pressure container;
- and
- a header with a phase-separating device arranged below the heat exchanger block, wherein the phase-separating device includes a base and wherein the base has a gas passage opening;
- and wherein the base has a discharge pipe disposed on a lower side of the base.
A reflux condenser, comprising:
- a heat exchanger block, wherein the heat exchanger block is enclosed by a pressure container;
- and
- a header with a phase-separating device arranged below the heat exchanger block, wherein the phase-separating device includes a base and wherein the base has a gas passage opening;
- and wherein a cover is arranged above the gas passage opening at a distance from the base.
A reflux condenser, comprising:
- a heat exchanger block, wherein the heat exchanger block is enclosed by a pressure container;
- and
- a header with a phase-separating device arranged below the heat exchanger block;
- in combination with a separating column, wherein the reflux condenser is arranged on a top of the separating column.
A method of conducting away a liquid from a lower region of a reflux passage of a heat exchanger block of a reflux condenser, comprising the steps of:
- flowing the liquid from the lower region of the reflux passage into a header which is arranged below the heat exchanger block;
- and
- flowing the liquid through the header via a discharge pipe.
