A fan 9 is installed between the bottom end of the air pipe 8 and the intake pipe 2. By arranging the fan 9, the air pipe 8 and the collection hood 7, the industrial waste gas inside the tower body 1 can be pumped into the intake pipe 2, which is convenient for rotating the industrial waste gas and fully desulfurizing the industrial waste gas.

[0022] In this embodiment, the gas-liquid separator 12 is arranged above the horizontal pipe 13, the swirl plate 14 is arranged below the horizontal pipe 13, the collection hood 7 is arranged on one side of the top of the gas-liquid separator 12, the bottom end of the air pipe 8 is fixedly connected to the air inlet of the fan 9, a second connecting pipe is fixedly arranged at the air outlet of the fan 9, a check valve 10 is fixedly installed on the second connecting pipe, and the second connecting pipe is fixedly communicated with the intake pipe 2. The arranged swirl plate 14 makes the industrial waste gas contact with the desulfurizing agent, and the gas-liquid separator 12 can separate the liquid in the industrial waste gas. The arranged check valve 10 is convenient for the industrial waste gas to circulate.

[0023] In this embodiment, the top end of the rotary spray head 16 is rotationally installed inside the bottom end of the fixed housing 15 in a limited manner. A connecting frame 19 is fixedly installed inside the top end of the rotary spray head 16. The shape of the connecting frame 19 is triangular. A turntable 18 is fixedly arranged at the top end of the connecting frame 19. The turntable 18 is rotationally installed inside the fixed housing 15. A rotating shaft is fixedly arranged at the center position of the top of the turntable 18. The rotating shaft penetrates through the top end of the fixed housing 15 and is arranged inside the horizontal pipe 13. An impeller 17 is fixedly arranged at the top end of the rotating shaft. The impeller 17 is arranged inside the horizontal pipe 13. The bottom of one end of the horizontal pipe 13 and the fixed housing 15 are interconnected through a third connecting pipe 20. The nozzles 21 are arranged in a matrix at the bottom of the rotary spray head 16. The desulfurizing agent entering the inside of the horizontal pipe 13 can impact the impeller 17, so that the impeller 17 drives the turntable 18 to rotate through the shaft rod. The turntable 18 drives the rotary spray head 16 to rotate through the connecting frame 19, which is convenient for evenly spraying the desulfurizing agent inside the tower body 1 through the rotary spray head 16 and the nozzles 21, and is convenient for the desulfurizing agent to fully contact with the industrial waste gas for desulfurization.

[0025] When using the desulfurization tower for treating industrial waste gas with controllable quantity, a valve and a pipeline are installed at the top of the exhaust port 6, and desulfurizing agent is added to the bottom inside the tower body 1. The water pump 3 extracts the desulfurizing agent through the first connecting pipe 5 and sends it into the interiors of the fixed pipe 4 and the cross pipe 13. The desulfurizing agent inside the cross pipe 13 impacts the impeller 17, causing the impeller 17 to rotate through the shaft rod and driving the turntable 18 to rotate. The turntable 18 drives the rotating spray head 16 to rotate through the connecting frame 19. At the same time, the desulfurizing agent inside the cross pipe 13 enters the interiors of the fixed housing 15 and the rotating spray head 16 through the third connecting pipe 20, and finally sprays out through the nozzle 21 to form a uniform atomized desulfurizing agent, avoiding dead angles during the spraying process. A quantitative amount of industrial waste gas is introduced into the interior of the tower body 1 through the air inlet pipe 2 and the air inlet pipe 2 is closed by the valve. The industrial waste gas entering the interior of the tower body 1 contacts the atomized desulfurizing agent under the action of the swirl plate 14. The industrial waste gas inside the tower body 1 is extracted through the fan 9, the air pipe 8 and the collecting hood 7, and is discharged into the interior of the air inlet pipe 2 through the second connecting pipe and the one-way valve 10. Finally, a cycle is formed among the tower body 1, the collecting hood 7, the air pipe 8, the fan 9 and the second connecting pipe, enabling the desulfurizing agent to fully contact the industrial waste gas and desulfurize, which can improve the desulfurization efficiency of the desulfurization tower and has high practicability; after desulfurization is completed, the industrial waste gas is discharged through the exhaust port 6.
