Description

Technical Field

[0001] The present application relates to the field of absorption and desorption, and in particular, to an absorption and desorption device. Background Art

[0002] The desorption tower is a device that uses gas or steam (gas phase) to separate part of the solute in the solvent (liquid phase). In a gas-liquid two-phase system, when the gas phase partial pressure of the solute component is lower than the gas-liquid equilibrium partial pressure of the component in its solution, mass transfer of the solute component from the liquid phase to the gas phase will occur. This process is called desorption or evaporation. For example, the process of releasing the absorbed gas from the absorption liquid, in the process of gasoline production, usually requires the use of a desorption tower to react with the rich gas.

[0034] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The reaction structure 20 includes a connecting plate 210, an air intake assembly 220, a mounting frame 230, a branch pipe 240 and a nozzle 250.

[0035] In the specific setting, the intake assembly 220 includes a rich gas compressor 221, a first hose 222, an intake pipe 223, a rotating seat 224 and a second hose 225. The rich gas compressor 221 is installed on one side of the tower body 110. The two ends of the first hose 222 are respectively connected to the rich gas compressor 221 and the intake pipe 223. The intake pipe 223 is arranged in the installation frame 230. The rotating seat 224 is rotatably connected to the intake pipe 223. The second hose 225 is threadedly connected to the rotating seat 224. The two ends of the second hose 225 are respectively connected to the intake pipe 223 and the branch pipe 240. Among them, through the setting of the rich gas compressor 221, the first hose 222, the intake pipe 223, the rotating seat 224 and the second hose 225, it is possible to facilitate the pressurization of the rich gas and the intake of the air.

[0036] In the specific configuration, a bearing is embedded on one side of the rotating seat 224, and the air intake pipe 223 is interference fit with the inner ring of the bearing. The interference fit between the air intake pipe 223 and the inner ring of the bearing can conveniently reduce the loss caused by the rotation.

[0037] In the specific configuration, the inner wall of the rotating seat 224 is provided with an internal thread, and the outer ring of the second hose 225 is provided with an external thread, and the internal thread is connected to the external thread. The second hose 225 can be easily disassembled and assembled through the connection between the internal thread and the external thread.
