Abstract

The invention provides a uniform gas distribution device for tower-type gas-liquid contact equipment and its application. The device includes a cylindrical tower body and more than two coaxial hollow cylinders arranged at the bottom of the tower body. The central axis of the cylindrical tower is the axis, and the inner diameter and length of each hollow cylinder are not equal, and there is a gap between two adjacent hollow cylinders; the bottom of each hollow cylinder is provided with an inverted tapered closing plate, A liquid discharge pipe is arranged on the closed plate; an air distribution plate is arranged at the bottom of the cylindrical tower, and there are holes on the air distribution plate, and the base of the air distribution plate is sealed and connected with the upper end of the hollow cylinder; An air inlet is provided below the wall. The device can realize the uniform distribution of air bubbles in the cross section of the tower body, the diameter of the air bubbles is uniform, and the device has a simple structure and is easy to process, and is especially suitable for large-scale air distribution equipment.

Description

technical field

[0001] The invention belongs to the field of chemical engineering, and relates to a uniform gas distribution device for tower-type gas-liquid contact equipment and its application. Background technique

[0002] The chemical reaction process often involves tower-type gas-liquid contact equipment. It is necessary to achieve uniform dispersion of bubbles in the liquid phase. This requires not only uniform distribution of the bubble dispersed phase per unit mass transfer height, but also uniform diameter of the bubble dispersed phase.

[0003] There have been many reports on the uniform gas distribution method and device for the gas-solid two-phase reaction. Patents CN 10250867A and CN202621144U both proposed a uniform gas distribution device for the suspension fluidization reaction of solid granular materials, but the gas distribution device is not applicable To produce bubbles of uniform diameter in a liquid.

[0004] Both patents CN 102728283A and CN 20270047...
