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

Embodiment 2

[0046] Refer to attached Figure 8~13 :Such as Figure 8 As shown, the liquid inlet structure includes an outer cylinder body 13, a liquid inlet port 14 and a liquid inlet hole 15. The outer cylinder body 13 is arranged on the upper part of the gradually expanding cone body 6 of the reaction section of the upper cavity, and the outer diameter is the same as that of the gradually expanding cone body of the reaction section. 6 have the same maximum outer diameter, a liquid inlet 14 is provided on the upper end surface of the outer cylinder 13, and a plurality of liquid inlet holes 15 are annularly provided on the inclined end surface of the upper cavity.

[0047] The inlet hole 15 can be as Figure 8~10 , a plurality of evenly distributed small holes shown in 12 can also be as Figure 11 with 13 The strip pores shown. The absorption liquid added in the gradually expanding cone 6 of the reaction section is sprayed through the liquid inlet 14 provided on the outer cylinder 13 ...

Abstract

The invention relates to an absorption-separation integrated cyclone reactor for desulfurizing sulfur-containing gas and belongs to the field of cyclone reactors for desulfurizing sulfur-containing gas. The cyclone reactor is characterized in that the outlet end of a mixing chamber (3) is sequentially communicated with a reaction mechanism and a separation mechanism in a reaction sequence; air inlet pipes are tangentially arranged at the upper part of the mixing chamber (3); first atomizing nozzles (2) are inserted onto the air inlet pipes; first level guide blades (4) are arranged between the mixing chamber (3) and the reaction mechanism; second level guide blades (8) are arranged between the reaction mechanism and the separation mechanism; each of the mixing chamber (3), the reaction mechanism and the separation mechanism comprises a cavity with a gradually varied inner diameter. The device provided by the invention integrates desulfurization and separation of sulfur containing gas and an absorption liquid. The gas-liquid contact area is increased and the gas-liquid transfer speed is accelerated by virtue of a high turbulence level of a swirling flow field, so that hydrogen sulfide in the sulfur containing gas is quickly absorbed, the reaction efficiency is effectively enhanced, and the reaction space is saved.

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...
