DETAILED DESCRIPTION

[0019] The technical solution of the utility model is further described below in conjunction with the accompanying drawings to make it easier to understand and grasp. The threaded structures, fasteners, pneumatic valves and other components involved are all commonly used by ordinary technicians in the field, and there is no special requirement for them in this case.

[0020] like Figure 1-2 As shown, the utility model is an assembled gas mixing column with a built-in spiral static mixer, including a gas mixing column body 1, on which a positioning block 13 is movably connected. The positioning block 13 can be used to fix the position of the gas mixing column body 1 for easy use.

[0021] Taking the center line of the gas mixing column body 1 along the Z-axis direction as a reference, the upper end of the center line is defined as the first end of the gas mixing column body 1 , and the lower end close to the center line is defined as the second end of the gas mixing column body 1 .

[0022] According to the technical solution of the utility model, a first fastener 3 is connected to the first end of the gas mixing column body 1, and the first fastener 3 is connected to an inlet end 5 through a first threaded structure 4, and an inlet pneumatic valve 6 is provided on the inlet end 5; a second fastener 7 is connected to the second end of the gas mixing column body 1, and the second fastener 7 is connected to an outlet end 11 through a second threaded structure 8, and an outlet pneumatic valve 12 is provided on the outlet end 11; a static mixer 2 is provided inside the gas mixing column body 1.

[0024] Preferably, if Figure 3 As shown, in the above structure: the static mixer 2 includes a liquid inlet 21, a double helix 22, a vortex mixing chamber 25 and a liquid outlet 26, the liquid inlet 21 is connected to the upper end of the vortex mixing chamber 25, the double helix 22 is arranged inside the vortex mixing chamber 25, and the liquid outlet 26 is connected to the lower end of the vortex mixing chamber 25.

[0025] Specifically, in the structure of the assembled gas mixing column with a built-in spiral static mixer, a buffer channel 23 is further provided inside the vortex mixing chamber 25, and the buffer channel 23 is respectively connected to the corresponding liquid inlet 21 and the liquid outlet 26, and has a buffering function, and a double helix 22 is rotatably provided inside the buffer channel 23. The double helix 22 is used to drive the cracking liquid to move and mix.

[0026] Specifically, in the structure of the assembled gas mixing column with a built-in spiral static mixer, the double helix 22 includes a centrally arranged rotating shaft, a spiral winding and a plurality of spiral blades, the spiral winding is spirally connected around the rotating shaft, the outer diameter of the plurality of spiral blades is not greater than 1 / 2 of the width and not less than 1 / 3 of the width, and the spiral blades are evenly welded on the surface of the spiral winding. The rotation effect of the double helix 22 is used to make the feed liquid reach the vortex mixing chamber 25 under the action of other equipment (for example: biological pump), and the double helix 22 is rotated by the action of the force, so as to uniformly stir the mixed feed liquid in all directions.

The seepage wall 24 is used to strengthen the flow guidance of the feed liquid, refine the filtered feed liquid, and improve the mixing degree.

[0028] Among the technical solutions of the utility model, the additional static mixer 2 is the technical key of this case. Figure 3 The focus is on the relevant components of the static mixer 2. For components such as threaded structures, fasteners, and pneumatic valves, ordinary technicians in this field can make conventional settings based on existing technologies. This case has no special requirements for their model selection and combined use.

[0029] In this way, by adopting the technical solution of the utility model, when the feed liquid enters the gas mixing column body 1 through the inlet end 5, gas is injected into the gas mixing column body 1 through the gas injection valve 10, and the static mixer 2 is used to assist in mixing the feed liquid inside it. By adjusting the mixing speed of the double helix 22, the diffusion randomness of the gas mixing in the viscous fluid can be effectively controlled to maintain the mixing uniformity.
