By setting the air inlet pipe 11 and the exhaust pipe 12, the high-concentration tail gas generated in the initial stage in the industrial enzyme preparation fermentation tank enters the main tank 1 through the air inlet pipe 11.

When the concentration of the tail gas generated by the fermentation tank is relatively high, while continuously adding the absorption solution into the main tank 1, the absorption solution in the main tank 1 is introduced into the secondary tank 10 through the first connecting pipe 132 and the second connecting pipe 20. The secondary tank 10 collects the absorption solution in the main tank 1 (this absorption solution can absorb the harmful substances in the low-concentration tail gas). When the concentration of the tail gas generated by the fermentation tank is relatively low, the reverse operation can be carried out to guide the absorption solution in the secondary tank 10 back into the main tank 1, and then treat the low-concentration tail gas, realizing the recycling and reuse of the absorption solution. A stirring mechanism 2 is provided on the device disk 14, and an air inlet mechanism 4 is provided on the bottom wall of the main tank 1. By setting the stirring mechanism 2 and the air inlet mechanism 4, when treating the low-concentration tail gas in the fermentation tank, the stirring mechanism 2 can stir the absorption solution and the low-concentration tail gas in the main tank 1, so that the low-concentration tail gas is fully mixed with the absorption solution, thereby improving the treatment effect of the tail gas and realizing the reuse of the absorption solution.

By driving the revolution and rotation of the stirring rod 21, the stirring rod 21 causes the stirring paddles 22 to revolve and rotate synchronously, and the stirring paddles 22 can fully stir the absorption solution and waste gas in the main tank 1. By starting the motor 3, the driving shaft of the motor 3 can cause the rotating rod 25 to rotate, and the rotating rod 25 can drive the first toothed rings 27 to rotate through the driving gear 26. The first toothed rings 27 can cause the first arc-shaped sliders 24 to slide circumferentially on the first circular track 23, and the first arc-shaped sliders 24 cause the stirring rod 21 and the stirring paddles 22 to revolve circularly. By providing the fixed toothed ring 28 and the fixed gear 29, the fixed gear 29 follows the circular revolution of the stirring rod 21, and the fixed toothed ring 28 drives the fixed gear 29 to rotate, and the fixed gear 29 can cause the stirring rod 21 and the stirring paddles 22 to rotate.

By providing the synchronous pulley 53 and the synchronous belt 54, when the rotating rod 25 rotates, the rotating rod 25 can make the first transmission rod 52 rotate through the synchronous pulley 53 and the synchronous belt 54.

[0035] Working principle: When it is necessary to treat the tail gas in the industrial enzyme preparation fermentation tank, an absorption solution is continuously injected into the main tank 1 through the injection pipe 13. In the initial stage, the high-concentration tail gas in the industrial enzyme preparation fermentation tank first enters the main tank 1 through the intake pipe 11, the connecting pipe 42, inside the air storage disc 41, multiple air holes 43, the first communication hole 45 and the second communication hole 48 (the second communication hole 48 coincides with the first communication hole 45). The high-concentration tail gas contacts the absorption solution in the main tank 1, and the absorption solution absorbs the harmful substances in the high-concentration tail gas. The high-concentration tail gas rises in the main tank 1 and is discharged through the exhaust pipe 12. At the same time, the absorption solution in the main tank 1 is introduced into the auxiliary tank 10 through the first connecting pipe 132 and the second connecting pipe 20 for collection;

[0036] When the concentration of the tail gas in the industrial enzyme preparation fermentation tank decreases, the absorption solution in the auxiliary tank 10 is guided back into the main tank 1 through the second connecting pipe 20 and the first connecting pipe 132, and the low-concentration tail gas enters the main tank 1 through the intake pipe 11, the connecting pipe 42, inside the air storage disc 41, multiple air holes 43, the first communication hole 45 and the second communication hole 48;

[0037] At this time, the operator turns on the motor 3, and the driving shaft of the motor 3 rotates the rotating rod 25, and the rotating rod 25 drives the first gear ring 27 to rotate through the driving gear 26, and the first gear ring 27 makes the two first arc surface sliders 24 slide circumferentially on the first circular track 23, and the two first arc surface sliders 24 make the stirring rod 21, the fixed gear 29 and the multiple stirring paddles 22 revolve in a circle, and the fixed gear ring 28 drives the fixed gear 29 to rotate, and the fixed gear 29 makes the stirring rod 21 and the stirring paddle 22 rotate. At this time, the stirring rod 21 and the multiple stirring paddles 22 revolve in a circle and rotate synchronously;

[0038] At the same time, the rotating rod 25 rotates the first transmission rod 52 through the synchronous wheel 53 and the synchronous belt 54, the first transmission rod 52 rotates the second transmission rod 55 through the two first bevel gears 56, the second transmission rod 55 rotates the third transmission rod 57 through the two second bevel gears 58, the third transmission rod 57 rotates the fan gear 59, the fan gear 59 drives the second gear ring 6 to rotate intermittently, the second gear ring 6 makes the two second arc surface sliders 5 intermittently slide in a circle, and the two second arc surface sliders 5 make the control disk 47 intermittently rotate through the two connecting frames 51 As the second connecting hole 48 gradually shifts away from and overlaps with the first connecting hole 45, when the two holes overlap, the low-concentration exhaust gas in the first connecting hole 45 quickly flows upward through the second connecting hole 48 to the absorption solution in the main tank 1 (it should be noted that the flow rate of the low-concentration exhaust gas entering the main tank 1 through the first connecting hole 45 and the second connecting hole 48 is greater than the downward pressure of the absorption solution). As the stirring paddle 22 revolves and rotates in a circle, the low-concentration exhaust gas is fully mixed with the absorption solution and a chemical reaction occurs. The absorption solution absorbs the harmful substances in the low-concentration exhaust gas.
