Efficient fractionating device for chemical engineering

Abstract

The invention relates to the technical field of chemical separation, and discloses an efficient fractionating device for chemical engineering. The device comprises a fractionating tower, the top end,the bottom end and the bottom end of the outer side wall of the fractionating tower are respectively provided with a gas discharge port, a liquid discharge port and a gas feed port, and a liquid feedhopper is encircled right below the top end of the fractionating tower, a liquid distribution tank is installed under the top end of a fractionating tower cavity, a first supporting plate is installedbelow the liquid distribution tank, a cavity defined by the first supporting plate, a first pressing plate and the inner side wall of the fractionating tower is filled with first filler, and a collection redistribution tank is installed below the first supporting plate; a second supporting plate is mounted right below the collection redistribution tank, and a cavity defined by the second supporting plate, a second pressing plate and the inner side wall of the fractionating tower is filled with second filler. According to the invention, the problems of low gas-liquid two-phase mass transfer efficiency, low liquid phase flux and high pressure drop in the fractionation operation process of a chemical fractionation device are solved.

Description

Technical field [0001] The present invention relates to the field of chemical separation techniques, and is specifically a highly active fractionation device for chemical. Background technique [0002] Chemical separation, the unique action of chemical equipment, the process of separating the specific mixture according to its physical properties and chemical properties, fractionation is an important method of chemical separation, fractionation is a mixture of several boiling points. Method, there is no new material generation during the process, but the original substance is separated, which belongs to physical changes, and the fractionation is heating a mixture, and cooling separately into a relatively pure single substance process for different boiling points of each component in the mixture. [0003] The present invention provides a highly efficient fractionation device for chemical, has a highly efficient fractionation chemical component, effectively improving gas phase trans...
