Abstract

The invention discloses a three-dimensional dynamic column plate which comprises a column plate and a three-dimensional dynamic mass transfer unit mounted on the column plate, wherein each three-dimensional dynamic mass transfer unit comprises a fixed end plate, a movable end plate, an injection plate and a separation plate; the bottom of the fixed end plate is mounted on the column plate, an injection channel is defined by the edge of the fixed end plate, the edge of the movable end plate, the side edge of the injection plate and the upper end of the separation plate, the injection plate is arranged on the side edge of the fixed end plate, and a movable groove is formed in the fixed end plate; a fixed part matched with the movable groove is formed at the lower part of the movable end plate and is used for moving up and down in the movable groove, the top of the movable end plate is connected with the separation plate, a gap is reserved between the separation plate and the upper part of the injection plate, and a lower gap is reserved between the lower part of the injection plate and the column plate. Compared with a traditional column plate, the operation flexibility of the column plate is improved to 30-200%; wherein the movable end plate moves up and down relative to the fixed end plate, so that the distance between the separation plate and the spraying plate is adjusted, the gas-liquid separation effect is improved, and the suitable operation range is wider.

Description

technical field [0001] The invention belongs to the field of mass transfer and heat transfer equipment in chemical engineering, and in particular relates to a three-dimensional dynamic tray. Background technique [0002] Tray tower is an important gas-liquid mass transfer equipment in chemical production, and its interior is composed of tray, downcomer plate, liquid receiving plate, support ring, support plate, overflow weir and so on. The mass transfer unit of the plate tower tray can be designed as sieve holes, floating valves, solid valves, vertical sieve trays, three-dimensional mass transfer trays, etc. [0003] As an important component of mass transfer equipment, trays are widely used in chemical separation operations. For a long time, people have focused on the development of individual mass transfer components, and there have been various forms of trays named after individual components, such as sieve holes, bubble caps, float valves, and improved on this basis. G...
