Description

Technical Field

[0001] The present application relates to the technical field of waste gas treatment, and in particular to an industrial waste gas desulfurization device. Background Art

[0002] Industrial waste gas refers to the gas containing various pollutants discharged during the industrial production process. These pollutants include sulfur dioxide, nitrogen oxides, carbon monoxide, volatile organic compounds, etc., which are harmful to the environment and human health. Industrial waste gas desulfurization refers to the treatment of sulfur dioxide in industrial waste gas through desulfurization equipment to reduce pollution to the environment.

[0003] The traditional industrial waste gas desulfurization device achieves the purpose of desulfurization by discharging the waste gas into the treatment liquid, and the treatment liquid reacts with the sulfide in the waste gas. However, in the actual production process, the waste gas is only passed into the treatment liquid, and a certain amount of unreacted waste gas escapes, which affects the treatment effect. Moreover, the treated waste gas is not tested, and there is still a possibility that the treated waste gas does not meet the standard. Therefore, in order to solve the above problems, the present application provides an industrial waste gas desulfurization device.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0009] Preferably, the outer wall of the connecting rod is fixedly connected with a plurality of evenly distributed first rotating rods, the number of which is the same as that of the vertical rods, and the rotation of the rotating plate does not interfere with the rotation of the first rotating rods.

[0010] Preferably, one end of the first rotating rod away from the connecting rod is rotatably connected to a connecting shaft, and the outer wall of the lower end of the connecting shaft is fixedly connected to a second rotating rod, and the second rotating rod does not interfere with the rotation of the first rotating rod.
