Abstract
A rotary counter-current solid/fluid contact apparatus is developed to enhance the efficiency of adsorption, ion exchange and regenerative heat exchange. The counter-current apparatus uses a rotor to direct fluids to multiple stationary columns. By the action of the rotor, counter-current flows of a fluid phase and a solid phase can be achieved for a combined adsorption and desorption cycle, or a combined heating and cooling cycle. The apparatus allows not only countercurrent solid-fluid flows based on columns in series, but also countercurrent solid-fluid flows in the length of each individual column. A method is also disclosed.
Claims7
A method for counter-current rotary fluid distribution in an apparatus, the apparatus having a rotor with a plurality of internal and external fluid passageways, and a plurality of columns in fluid communication with the plurality of external fluid passageways of the rotor, the external fluid passageways of the rotor arranged to provide either a top-to-bottom (down) flow or a bottom-to-top (up) flow through a column, the method comprising the steps of:
- passing a fluid into one of the external fluid passageways of the rotor;
- flowing the fluid from said one of the external fluid passageways of the rotor into a top of one of the plurality of columns such that the fluid flows internally from the top of the one of the plurality of columns to the bottom of the one of the plurality of columns;
- returning the fluid externally from the bottom of the one of the plurality of columns to a top section of another of the plurality of columns, such that the fluid flows internally from the top of the another of the plurality of columns to the bottom of the another of the plurality of columns;
- removing the fluid from the apparatus;
- and
- rotating the rotor such that the external fluid passageways of the rotor are oriented to flow another fluid internally from the bottom of the one of the plurality of columns to the top of the one of the plurality of columns.
