Technical Field

[0001] This invention relates to the field of exhaust gas scrubbing tower technology, and more specifically to an exhaust gas scrubbing tower with an internal coil exhaust device. Background Technology

[0002] A tail gas purification tower is a device used to treat the exhaust gases emitted by various equipment. The exhaust gases produced by various equipment may contain harmless nitrogen, oxygen and carbon dioxide, as well as sulfur dioxide and acid mist that pollute the air. Therefore, the exhaust gases must be purified to meet emission standards before they can be discharged, in order to avoid pollution and harm to the external environment.

[0003] Existing exhaust gas purification towers often chemically treat exhaust gas to prevent harmful substances from being transported to the outside world and causing environmental pollution. However, the high temperature of the exhaust gas can still harm the external environment. Therefore, to avoid the emission of high-temperature exhaust gas, we need an exhaust gas scrubbing tower with an internal coil exhaust device. Summary of the Invention

[0018] 2. This invention uses a water pump to transport water from the tank to the spiral tube. Simultaneously, the rotation of the support shaft drives the first and second pulleys, which are connected by belts, to rotate. The second pulley then drives the fifth blade on the positioning shaft to rotate, agitating the air and ensuring full contact with the spiral tube. This ensures efficient heat dissipation from the spiral tube and effectively cools the water. The cooled water, when sprayed from the second nozzle on the tank, further enhances the cooling effect on the exhaust coil, thus cooling the exhaust gas. The sprayed water then returns through a connecting pipe, thereby improving the utilization efficiency of the water and avoiding resource waste. Attached Figure Description

Then, the rotation of the positioning shaft 35 drives the fifth fan blades 37 to rotate, thereby enhancing the air flow outside the spiral tube 38 and improving the heat dissipation efficiency of the spiral tube 38.

[0039] To improve the heat dissipation efficiency of the exhaust coil 18, the heat on the exhaust coil 18 is carried away and drawn to the outside environment by the combined action of air and water, such as...

[0040] To prevent the purification liquid from overheating and affecting its heat dissipation efficiency for the exhaust gas, the rotation of the positioning shaft 35 drives the fifth fan blade 37 to dissipate heat from the spiral tube 38. Figure 1 , 2 As shown in Figures 4 and 8, a first pulley 43 is fixedly sleeved on the outside of the support shaft 34.

[0042] Water from tank 1 is pumped into spiral tube 38 by pump 39. Simultaneously, the rotation of support shaft 34 drives the first pulley 43 and the second pulley 44 connected by belt 45 to rotate. The second pulley 44 drives the fifth fan blade 37 on positioning shaft 35 to rotate, stirring the air to ensure full contact with spiral tube 38, ensuring efficient heat dissipation of the spiral and achieving the purpose of cooling the water. When the cooled water is sprayed out by the second nozzle 41 on the housing 40, it can improve the cooling effect on exhaust coil 18, achieving the purpose of cooling exhaust gas. The sprayed water is then returned through connecting pipe 42, thereby improving the utilization efficiency of water and avoiding waste of resources.
