High-efficient gas-liquid mass transferring device

Abstract

The invention discloses a high efficient gas and liquid mass transfer rig. A defoaming plate, a liquid distributor and a multilevel gas and liquid exchanging device is arranged in a tower body up and down, the bottom of the tower body is a liquid collecting chamber, the top of the tower body is an air gate; the invention uses the character of H2S and aqueous alkali which can proceed chemical reaction quickly and adopts gas and liquid direct contact, makes liquid and gas moving contact, turbulent motion mass transfer, the contact area between the liquid and the gas is increased greatly, makes the gas realize full mixing contact with the liquid and improves the purifying degree. The invention doesn't use filling, which solves the blocking problem in the filling desulfurizer and has simple structure, convenient installation, large operating flexibility, low tower resistance, low production cost and remarkable practical application effect.

Description

Technical field: [0001] The invention is an improvement on the structure of the existing wet desulfurization desulfurization tower, and in particular discloses a high-efficiency gas-liquid mass transfer device, which belongs to the technical field of chemical equipment. Background technique: [0002] At present, most wet desulfurization towers basically use packed towers. Due to different packing specifications and models, the mass transfer area is different. However, the design department can be based on the gas volume, hydrogen sulfide content and Different towers are designed depending on the selected packing. In short, they can meet the production needs, that is, they can generally meet the requirements of gas purification. However, with the continuous expansion of the production scale of enterprises and the adjustment of subsequent product diversification, enterprises have become more and more stringent on desulfurization requirements. The disadvantages brought by the packed...
