Gas-liquid mass transfer device

Abstract

The invention relates to a gas-liquid mass transfer device. The gas-liquid mass transfer device comprises a tower body, more than two mass transfer unit groups, an independent liquid collector, an independent liquid receiving tray and gas blocking plates, wherein a gas phase outlet and a liquid phase inlet are formed in the top of the tower body; a liquid phase outlet and a gas phase inlet are formed in the bottom of the tower body; each mass transfer unit group comprises a liquid collector, a liquid receiving tray, a liquid distributor and a mass transfer zone from top to bottom; the more than two mass transfer unit groups are arranged inside the tower body in the longitudinal direction; the independent liquid collector and the independent liquid receiving tray are located below the bottommost mass transfer unit group; the gas blocking plates are located at the two sides of each mass transfer unit group and are fixedly connected to the liquid collector, so that an air inlet is formedin the top of each mass transfer unit group, and an air outlet is formed in the bottom of each mass transfer unit group; and the liquid collectors and the liquid receiving trays in the mass transfer unit groups are matched with the set height of a water head. The gas-liquid mass transfer device combines the advantages of both countercurrent and parallel flow, can simultaneously realize relativelylarge mass transfer driving force and sufficiently stable gas-liquid contact, increases the mass transfer rate, and ensures the mass transfer effect.

Description

technical field [0001] The invention belongs to the technical field of gas-liquid mass transfer device, in particular to a gas-liquid mass transfer device Background technique [0002] The gas-liquid mass transfer process refers to the transfer of substances between the gas and liquid phases. It mainly includes unit operations such as gas absorption, gas dehumidification (or dehumidification), and liquid distillation (or rectification). Gas-liquid mass transfer equipment gas-liquid masstransfer equipmeru, also known as gas-liquid contact equipment (gas-licruid c}ntaci equipment), is used for gas-liquid mass transfer process equipment. Gas-liquid mass transfer equipment mainly includes plate tower and packed tower, which are the most widely used equipment in rectification and absorption. Others include spray tower, horizontal tower, bubble tower, wet wall tower, etc. In addition to mass transfer in gas-liquid mass transfer equipment. Sometimes it is accompanied by heat tran...
