Problems solved by technology

However, in the prior art, the gas injection pipe passes through the gas dispersion plate from the top of the absorption tower into the gas layer area. The gas dispersion plate is not only complex in structure, difficult to manufacture, install and maintain, but also supported and fastened with other components, which cannot Adjusting the levelness at the application site will seriously affect the operation and processing efficiency of the jet bubble tower
Furthermore, the gas to be processed is introduced into the lower part of the gas dispersion plate from the injection tube, impacts the liquid surface and entrains the liquid to pass through the injection hole and then rises. The amount of liquid carried at different positions in the radial direction is uneven. The larger the liquid volume, the smaller the liquid carried by the gas rush in the area away from the injection tube, which reduces the gas-liquid contact efficiency
Secondly, the injection pipe passes through the gas dispersion plate from the top of the absorption tower, which makes the space utilization efficiency above the absorption tower low and increases the volume and cost of the equipment

Abstract

The invention belongs to gas-liquid mass transfer devices in the technical fields of chemical engineering and environmental protection and is applied in technical processes, such as distillation, absorption, separation, washing, purification and the like. A thin-hole sieve-plate-typed bubble column comprises a cylinder body, a gas inlet, a gas outlet, a micro-channel thin-hole sieve plate, an imbibing breathable net and a downflow apparatus. A liquid phase is fed to the imbibing breathable net and is carried by a gas fed into the bubble column to form a gas-liquid mixture. The gas-liquid mixture passes through the micro-channel thin holes in the sieve plate to form a bubbling layer above a column plate. In the thin-hole sieve-plate-typed bubble column, the micro-channel thin-hole sieve plate and the imbibing breathable net are employed and a method of supplying the liquid from under the plate is employed so that the gas-liquid flow is formed and is passed through the micro channels, thereby significantly increasing a gas-liquid contacting area and enhancing a mass transfer process. The thin-hole sieve-plate-typed bubble column is simple in structure, is stable in operation, is convenient to maintain, is less in pressure loss and liquid consumption amount, and is low in device cost and operation energy consumption.

Description

technical field [0001] The invention relates to a bubble tower, which belongs to gas-liquid mass transfer equipment in the technical field of chemical industry and environmental protection, and can be widely used in the processes of distillation, absorption, separation, washing, purification and the like in chemical industry, environmental protection, smelting, light industry and other industries. Background technique [0002] Absorption tower is an important purification device and process for treating volatile pollutants and dust in gas. It can typically be divided into spray tower (spray tower), packed tower, plate tower and jet bubbling tower (Jet bubbling tower) ). According to the power source of gas-liquid contact, the absorption tower can be divided into a liquid injection method that injects liquid into the gas phase and a gas injection method that injects gas into the liquid phase. In order to improve the treatment efficiency and reduce investment and operation co...
