Description

Technical Field

[0002] Sulfur trioxide, a colorless, easily sublimated solid, has three physical states. Its gaseous form is a serious pollutant and one of the main sources of acid rain. Therefore, when tail gas emissions occur in related production, they need to be purified before being discharged.

[0003] In the patent document with the existing patent announcement number CN219399474U, a filter for flue gas desulfurization is disclosed. By setting a spray head and a filter element, the flue gas enters the inside of the filter box from the air inlet pipe, and the water pump is started. The water pump conveys the water inside the water tank to the spray head. The spray head sprays water on the flue gas. The soot and other impurities in the flue gas are wrapped by water droplets and fall on the filter element. The filter element absorbs the water droplets, and the water penetrates the filter element. The soot and other impurities are intercepted inside the filter element. The filtered gas inside the filter box is discharged from the air outlet pipe, and the water is discharged from the drain pipe at the bottom.

[0004] However, when the device is actually operated, the smoke will move irregularly. Without external force control, the smoke and water will not be mixed sufficiently. The smoke will even pass directly through the filter element, affecting the overall operation effect. Utility Model Content

The other end of the air guide pipe 242 is used to connect to the smoke exhaust port of the chemical equipment.

[0036] During operation, the air guide pipe 242 is connected to the smoke exhaust port of the chemical equipment, and the smoke enters the air distribution pipe 241 through the air guide pipe 242 and is discharged through a plurality of small holes outside the air distribution pipe 241 .

[0037] To implement the function of the drive assembly 250, please refer to Figure 2-4 The driving assembly 250 includes a motor 251 and two gears 252. The motor 251 is fixedly connected to one side of the shell 100. One end of the output shaft of the motor 251 passes through the inner wall of the shell 100 and is fixedly connected to one end of the rotating roller 220. The two gears 252 are respectively fixedly connected to the other ends of the two rotating rollers 220, and the two gears 252 are meshed with each other.

[0038] During operation, the motor 251 drives one of the rotating rollers 220 , and the other end of the rotating roller 220 drives the other rotating roller 220 through the gear 252 , so that the stirring blades 230 outside the two rotating rollers 220 can rotate in different directions.

[0039] In order to realize the function of the filter mechanism 300, please refer to Figure 1-5 The filtering mechanism 300 includes a filter element 310 and a discharge pipe 320. The outer side of the filter element 310 is fixedly connected to the inner wall of the housing 100. The bottom of the filter element 310 corresponds to the top of the mixing tank 210. The discharge pipe 320 is arranged at the top of the filter element 310. An air pump 321 is arranged inside the discharge pipe 320. The air pump 321 is used to allow the gas discharged from the mixing tank 210 to pass through the filter element 310. The other end of the discharge pipe 320 passes through the outer side of the top of the housing 100.

[0040] During operation, the air pump 321 draws air in the direction of the filter element 310 , so that the air at the bottom of the filter element 310 can pass upward through the filter element 310 , so that the smoke is filtered and then discharged to the next stage through the exhaust pipe 320 .

[0041] To ensure the mixing effect of the mixing tank 210, please refer to Figure 3 A liquid inlet pipe 212 is provided at the top of one side of the mixing tank 210 , and a liquid discharge pipe 213 is provided at the bottom of the opposite side of the mixing tank 210 .

[0043] A support frame 400 is disposed at the bottom of the housing 100 .

[0044] The working principle of the above-mentioned treatment device in actual use is as follows: during operation, the air guide pipe 242 is connected to the exhaust port of the chemical equipment, and the smoke enters the gas distribution pipe 241 through the air guide pipe 242, and is discharged into the mixing tank 210 through a number of small holes outside the gas distribution pipe 241. The mixing tank 210 contains a treatment liquid, which can react with the corresponding substances in the smoke to make the smoke discharged separately;

[0045] Furthermore, the stirring blades 230 are in contact with the inner wall of the mixing tank 210 and the outer side of the horizontal plate 211, and are always in contact with each other to form a seal. At the same time, the motor 251 is driven, and the motor 251 drives one of the rotating rollers 220. The other end of the rotating roller 220 drives another rotating roller 220 through the gear 252, so that the stirring blades 230 outside the two rotating rollers 220 can rotate in different directions. The smoke is discharged along the gaps between the stirring blades 230. The rotation speed of the stirring blades 230 can be controlled to control the reaction time of the smoke and the treatment liquid.

[0046] Furthermore, the smoke discharged from the mixing tank 210 can be sucked by the air pump 321. Under the suction of the air pump 321, the gas at the bottom of the filter element 310 can pass upward through the filter element 310, so that the smoke is filtered and then discharged to the next stage through the exhaust pipe 320.

[0047] Furthermore, the treatment liquid inside the mixing tank 210 can be updated through the liquid inlet pipe 212 and the liquid discharge pipe 213 outside the mixing tank 210 to ensure the mixing effect;

[0048] The device is easy to operate, has multi-stage processing, and the mixing time is controllable, which can ensure that the flue gas and the solution can be mixed more fully and the operating effect is good.

[0049] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be covered within the protection scope of the present invention.
