Absorption and separation integrated sulfur-containing gas desulfurization cyclone reaction device

Abstract

The invention relates to an absorption and separation integrated sulfur-containing gas desulfurization swirl reaction device, which belongs to the field of swirl reactors for sulfur-containing gas desulfurization. It is characterized in that: the outlet end of the mixing chamber (3) is sequentially connected to the reaction mechanism and the separation mechanism according to the reaction sequence, the air inlet pipe is arranged tangentially on the upper part of the mixing chamber (3), and the first atomizing nozzle (2) Inserted on the intake pipe, a first-stage guide vane (4) is provided between the mixing chamber (3) and the reaction mechanism, and a second-stage guide vane (8) is provided between the reaction mechanism and the separation mechanism. The mixing chamber ( 3) Both the reaction mechanism and the separation mechanism include a cavity with a gradually changing inner diameter. The invention realizes the integration of the desulfurization reaction and separation of the sulfur-containing gas and the absorption liquid, utilizes the high turbulence of the swirl field to increase the gas-liquid contact area, accelerates the gas-liquid mass transfer rate, and rapidly absorbs the hydrogen sulfide in the sulfur-containing gas , which effectively improves the reaction efficiency and saves the reaction space.

Description

technical field [0001] The invention relates to an absorption and separation integrated sulfur-containing gas desulfurization swirl reaction device, which belongs to the field of swirl reactors for sulfur-containing gas desulfurization. Background technique [0002] There are many desulfurization methods for sulfur-containing refinery gas and natural gas, such as chemical absorption method, physical absorption method, mixed absorption method, fixed bed adsorption method, membrane separation method and direct conversion method, etc. Each method has its own advantages and disadvantages, but The chemical absorption method is the most used in industrial applications, that is, amine desulfurization. [0003] There are two types of traditional amine desulfurization devices: plate tower and packed tower. The plate tower is composed of multi-layer trays. The desulfurization tower generally has 20~24 trays. The driving force for the mass transfer of the solute between the gas-liquid...

AI Technical Summary

Problems solved by technology

Traditional packing types such as Raschig rings, Pall rings, stepped rings, and corrugated plate packings are not efficient, and new random and structured packings are more efficient, but relatively expensive

The overall height of the packed tower is lower than that of the plate tower, but the inner height of the tower needs to increase the space required for internal components such as manholes, distributors, collectors, and redistributors on the basis of the height of the packing. Usually, the height of the packed absorption tower for desulfurization remains the same. It is more than six meters, which also causes the internal structure of the packed tower to be complicated, and the installation and maintenance are more difficult
