[0014] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] like Figure 1 As shown, according to an embodiment of the present invention, a wet desulfurization absorption tower is provided, including a tower body 1 and an overflow pipe connected to the tower body 1. An overflow port 101 is provided on the side wall of the tower body 1. The overflow pipe includes a first vertical pipe 2 and a second vertical pipe 3. The bottom end of the first vertical pipe 2 is connected to the overflow port 101 through a connecting pipe 4. A first drain port 201 is provided on the upper part of the first vertical pipe 2, and a second drain port 301 is provided on the top of the second vertical pipe 3. The first drain port 201 is connected to the second drain port 301 through a connecting pipe 5. The height of the overflow port 101 is lower than that of the first drain port 201. The height of the second drain port 301 is lower than that of the first drain port 201. A nozzle 6 is provided inside the first vertical pipe 2. The nozzle 6 is provided with a first nozzle 601 for spraying defoamer into the first vertical pipe 2 and a second nozzle 602 for spraying defoamer into the second vertical pipe 3. The nozzle 6 is connected to a first conveying pipe 7.

[0016] The delivery pipe 7 is connected to the tank 8. The top of the tank 8 is fixedly connected to the tank 9. The top of the tank 9 is equipped with a tank cover 901. The tank 9 is used to store defoamer. The top of the tank 8 is equipped with a liquid inlet channel and a liquid inlet valve 10. Opening the liquid inlet valve 10 can add the solution in the tank 9 to the tank 8.

[0017] Tank 8 is connected to a process water delivery pipe 11; a valve is installed on the process water delivery pipe 11.

[0018] Tank 1 8 is connected to the trench via vent pipe 12, and a valve is installed on vent pipe 12; vertical pipe 2 3 is connected to the trench.

[0019] The working principle of the above embodiment is:

[0020] In the daily state, the process water enters the tank body 8, and then is transported to the spray head 6 through the conveying pipe 7 to provide the process water for the spray head 6, and the process water sprayed by the spray head 6 can play a role in preventing the slurry from foaming in daily use;

[0021] When the foam needs to be removed due to excessive foam, the defoaming agent in the tank body 2 is added to the tank body 1; then under the pressure of the process water, the defoaming agent is transported to the spray head 6; the defoaming agent sprayed by the spray port 1 601 enters the tower body 1 through the vertical pipe 1 2, and the defoaming agent sprayed by the spray port 2 602 enters the vertical pipe 3; so that the foam in the overflow pipe and the tower body 1 can be eliminated; the problems of slurry foaming and overflow affecting the safe operation of the system and causing environmental pollution can be avoided.
