DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1 - Figure 5 The exhaust gas washing mechanism shown includes a spray tower 1, a fan 2 and a circulating water pump 3. The spray tower 1 is a device for adsorbing exhaust gas. The spray tower 1 is used to adsorb harmful substances in the exhaust gas, and the fan 2 is responsible for guiding the exhaust gas to be treated into the spray tower 1 for the adsorption process. A spray device is also arranged on the inner wall of the spray tower 1. This set of equipment is driven by the circulating water pump 3 outside the spray tower 1 to realize the recycling of the spray liquid, thereby more effectively washing the pollutants in the exhaust gas.

[0023] The inner wall of the spray tower 1 is provided with an adsorption component 4 for adsorbing the tail gas, and the component is mainly used for efficiently adsorbing harmful substances in the tail gas, so as to further improve the effect of the tail gas treatment.

[0024] The adsorption component 4 includes a support sleeve 401, an arcuate pipe 402, a rotating rod 403, a rotating disk 404, a guide strip 405, a first packing layer 406, a first inclined plate 407, a second inclined plate 408, a second packing layer 409, a carrier plate 410 and a third packing layer 411. The support sleeve 401 is arranged on the inner wall of the spray tower 1, the arcuate pipe 402 is arranged in the middle of the support sleeve 401, and the arcuate pipe 402 is connected to the support sleeve 401. The outer wall of the arcuate pipe 402 is connected to the output end of the fan 2 through the first connecting pipe 9. The rotating rod 403 is rotatably arranged on the inner wall of the support sleeve 401, and the rotating disk 404 is arranged on the outer wall of the rotating rod 403. The outer wall of the rotating disk 404 is provided with multiple and equidistant arcuate strips 7, which can increase the contact area between the exhaust gas and the rotating disk 404 when the fan 2 blows out the exhaust gas, so that the exhaust gas can be more widely dispersed.

[0025] The guide strip 405 is arranged on the inner wall of the spray tower 1, the first packing layer 406 is arranged on the inner wall of the spray tower 1 above the guide strip 405, the first inclined plate 407 and the second inclined plate 408 are arranged on the inner wall of the spray tower 1 above the first packing layer 406, the second packing layer 409 is arranged on the inner wall of the spray tower 1 above the first inclined plate 407 and the second inclined plate 408, the carrier plate 410 is arranged on the inner wall of the spray tower 1 above the second packing layer 409, and the third packing layer 411 is arranged on the surface of the carrier plate 410.

[0026] The guide strip 405 is V-shaped and has a through hole 5 in the middle. The fan 2 sprays the exhaust gas upward from the support sleeve 401 along the arc-shaped pipe 402. Due to the guidance of the arc-shaped pipe 402, the exhaust gas forms a vortex shape. This shape not only increases the contact area between the exhaust gas and the rotating disk 404, but also can more effectively promote the rotation of the rotating disk 404, thereby realizing the rotational diffusion of the exhaust gas, significantly expanding the area and range of exhaust gas emissions. When the exhaust gas further contacts the guide plate, part of the exhaust gas is discharged upward through the through hole 5 of the guide plate, while most of the exhaust gas rises and is discharged along both sides of the guide plate.

[0027] A through hole 5 is provided in the middle of the first packing layer 406, and multiple equidistant air holes 6 are provided on both sides. When part of the exhaust gas passes through the through hole 5 of the guide plate, it will first contact with the first packing layer 406 and be adsorbed by it. At the same time, most of the exhaust gas will pass through the pores of the first packing layer 406 and fully contact with the first packing layer 406 during the flow process, so as to be effectively adsorbed.

[0028] The surface of the second packing layer 409 is provided with multiple and equidistant air holes 6. When the exhaust gas passes through the first packing layer 406, it will come into contact with the water sprayed by the spraying equipment for spraying and adsorption. This process effectively removes some harmful substances in the exhaust gas. The exhaust gas after spraying continues to rise and is guided by the first inclined plate 407. It comes into contact with the second inclined plate 408 along the direction of the inclined plate. At the contact point between the first inclined plate 407 and the second inclined plate 408, the exhaust gas also comes into contact with the second packing layer 409. The second packing layer 409 further adsorbs the substances attached to the exhaust gas, thereby achieving further purification and adsorption of the exhaust gas.

[0029] A through hole 5 is provided in the middle of the carrier plate 410, and multiple and equidistant air holes 6 are provided on both sides. When the rising exhaust gas contacts the carrier plate 410, part of the exhaust gas directly passes through the through hole 5, while most of the exhaust gas flows to the third filler layer 411 through the air holes 6 and is adsorbed thereon. Afterwards, the exhaust gas continues to rise and meets the spraying equipment at the top for secondary adsorption treatment.

[0030] It should be noted that the diameter of the air pores 6 is smaller than that of the through holes 5 in order to slow down the rising speed of the exhaust gas. As the pore diameter decreases, the exhaust gas flow rate slows down, which helps the packing layer and the spraying equipment to contact the exhaust gas more fully, thereby improving its adsorption effect.

[0031] The utility model also provides a waste perchloric acid treatment device, which is mainly used to stir the waste perchloric acid to promote the release of acidic gas. Subsequently, the released acidic gas will be transported to the spray tower 1 through the fan 2 for adsorption, thereby achieving the purpose of purifying the gas.

[0032] It includes a tank body 8, a gas outlet 804 is arranged on the top of the tank body 8, a feed port for adding liquid is arranged on one side of the tank body 8, a motor 801 is arranged on the top of the tank body 8, a stirring rod 802 is rotatably arranged on the inner wall of the tank body 8, a stirring blade 803 is arranged on the outer wall of the stirring rod 802, the gas outlet 804 is connected to the input end of the fan 2 through the second connecting pipe 10, and the motor 801 is driven to rotate, and the stirring rod 802 is driven to rotate by the motor 801, and then the fan 2 is driven to transport the acid gas generated by stirring the perchloric acid in the tank body 8 to the spray tower 1 for adsorbing impurities.
