Problems solved by technology

However, under the condition that the cross-sectional area of ​​the tower remains constant, the mass transfer area will inevitably be reduced, thereby reducing its mass transfer efficiency and the processing efficiency of the plate tower; at the same time, limited by the cross-sectional area of ​​the tower, the opening ratio Generally around 12%, not more than 20%, the limitation of the opening ratio reduces the contact area of ​​the gas-liquid phase, further affecting the mass transfer efficiency

Abstract

The invention discloses a combined trapezoid spray tray. The combined trapezoid spray tray comprises a tray body as well as a plurality of sieve holes and a plurality of float valve structures arranged on the tray body, wherein each float valve structure comprises a valve hole formed in the tray body, an inverted conical barrel nested in the valve hole and fixedly connected with the tray body, a support fixed on the tray body, a support rod connected with the support and inserted into the inverted conical barrel and a float piece arranged on the support rod in a sleeving manner, and the upper edge of the inverted conical barrel is higher than the surface of the tray surface. The combined trapezoid spray tray is high in mass transfer efficiency and high in flux. The invention further provides a plate column.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a three-dimensional mass transfer tray and a tray tower. Background technique [0002] Tray tower is a kind of graded contact mass transfer equipment used in gas-liquid or liquid-liquid system. It consists of a tower body and a number of trays distributed in the tower body at a certain distance. It is widely used in rectification and absorption. Taking the gas-liquid system as an example, the liquid flows through each layer of trays from top to bottom under the action of gravity during operation, and is discharged from the bottom of the tower; the gas is driven by pressure difference, and passes through each layer of towers from bottom to top in sequence. Plate, discharged to the top of the tower. Each tray maintains a liquid layer at a certain height, and the gas is dispersed into the liquid layer through the tray for interphase contact and mass transfer. [0003] T...
