[0033] Through the above operations, the gas can be made to come into full contact with the liquid in the mixing tank 1.

[0034] Specifically, the liquid material is added to the mixing tank 1 through the liquid inlet pipe 20. After the addition is completed, the pneumatic conveying pump 3 is started.

[0044] ​

[0045] At the same time, the existence of the drag reduction hole 14 makes the C-shaped stirring rod 13 encounter less resistance, reducing the operating load of the motor 12;

[0046] While stirring, some gas that has not reacted yet accumulates at the top of the inner cavity of the stirring tank 1. At this time, the gas suction pump 9 can be started to transport the gas accumulated at the top of the inner cavity of the stirring tank 1 to the inner cavity of the gas delivery sheet 4 through the gas suction pipe 10, and then the gas is discharged through the vent head 8 to react with the liquid material, thereby improving the utilization rate of the gas material;
