[0011] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0013] (2) The temperature of the exhaust smoke is reduced by the heat absorption effect of water evaporation. In addition to solid particles, some harmful gases such as sulfur dioxide and hydrogen chloride can also dissolve in water or react with water to form soluble substances, thereby being effectively removed;

[0014] (3) The driving member drives the dispersion outlet member to rotate, and stirring can fully mix the water and smoke, increase the contact area between water molecules and smoke particles, and when water molecules contact the surface of smoke particles, they can begin to dissolve those soluble components. Stirring breaks the static state and ensures that more water molecules have the opportunity to contact different parts of the smoke particles, thereby improving the dissolution efficiency. At the same time, stirring helps to evenly distribute heat and prevent local overheating or overcooling, which is very important for maintaining the temperature conditions during the dissolution process, especially when the dissolution process is accompanied by significant thermal effects;

[0015] (4) During the dust removal process, water is filtered through the circulating water filter and transported to the spraying part, which sprays the smoke and dust again. The water mist can increase the particle size through condensation, making it easier to settle or be captured. It can effectively capture and remove particulate matter in the smoke, especially for fine dust particles. The smoke after dust removal is discharged through the exhaust port, and the particulate matter in the smoke is removed by physical interception through the exhaust part.

[0031] Specifically, the spray member 8 includes a spray ring 81, a spray head 82, a fixing rod 83 and a second delivery pipe 84. The spray ring 81 is hollow and the spray heads 82 are evenly distributed at the lower end. The fixing rods 83 are arranged in a circular array in the dust removal box 1. One end of the fixing rod 83 is fixedly mounted on the inner wall of the dust removal box 1 and the other end is fixedly mounted on the outer wall of the spray ring 81. One end of the second delivery pipe 84 is connected to the spray ring 81 and the other end is connected to the first delivery pipe 71.

[0036] The reinforcement rod 101 and the movable shaft 102 can increase the stability of the rotation of the central shaft 4 and help the central shaft 4 to run stably. Reinforcement can reduce the vibration and shaking of the rotating shaft 4 during operation, improve the stability and accuracy of the system, and through reinforcement, the fatigue life of the rotating shaft 4 is extended, reducing the early failure caused by material fatigue, reducing the failure rate of the central shaft 4, extending the service life, reducing the replacement frequency, and reducing maintenance costs and downtime.

The dust removal box 1 contains a purification medium, which is generally set to water. The evaporation and heat absorption of water reduce the temperature of the discharged smoke. At the same time, in addition to solid particles, some harmful gases such as sulfur dioxide and hydrogen chloride can also be dissolved in water, or react with water to form soluble substances, which are then effectively removed. During the transportation process, the dispersed gas outlet member 6 is driven to rotate by the driving member 5, and the stirring can fully mix the water and smoke, increase the contact area between water molecules and smoke particles, and when water molecules contact the surface of the smoke particles, they can open The stirring breaks the static state and ensures that more water molecules have the opportunity to contact different parts of the smoke particles, thereby improving the dissolution efficiency. At the same time, stirring helps to evenly distribute heat and prevent local overheating or overcooling. This is very important for maintaining the temperature conditions during the dissolution process, especially when the dissolution process is accompanied by significant thermal effects. During the dust removal process, the water is circulated and filtered through the circulating water filter 7 and transported to the spray part 8. The smoke is sprayed by the spray part 8 to filter the smoke again. The water mist can increase the particle size through coagulation, making it easier to settle or be captured, and can effectively capture and remove particulate matter in the smoke, especially for fine dust particles. The smoke after dust removal is discharged through the exhaust port, and the particulate matter in the smoke is removed by physical interception through the exhaust part 9, ensuring the filtering and dust removal effect of the smoke, which is beneficial to the health of workers and the protection of the environment.
