By providing a spray mechanism that can move up and down, the function of spraying at different heights inside the tower body 1 is realized. The movable component 11 of the spray mechanism can rotate, and the motor drives the gear to mesh with the teeth on the first diverter plate 111, which can drive the spray plate to rotate and expand the spray range. The design of the bellows 10 ensures that the connection between the water inlet pipe 2 and the spray mechanism will not be affected when the spray mechanism moves up and down. The arrangement of the water inlet pipe 2, the air inlet pipe 6, the drain pipe 7 and the exhaust pipe 8 enables the device to achieve the function of processing and discharging exhaust gas.

[0025] As a preferred embodiment of the present invention, a diversion net 112 is fixedly connected to the inner wall of the first diversion plate 111. The diversion net 112 is fixedly connected to the inner wall of the first diversion plate 111, so that the spray water can be more evenly distributed inside the tower body 1, increasing the contact area between water and tail gas and improving the efficiency of tail gas treatment.

[0026] As a preferred embodiment of the present invention, a bottom support cover 4 in the shape of an annular shape is integrally formed at the bottom of the tower body 1, and both the air inlet pipe 6 and the drain pipe 7 pass through the bottom support cover 4, and a base 5 is welded at the bottom of the bottom support cover 4. The bottom support cover 4 provided at the bottom of the tower body 1 enhances the stability of the device, and the welding of the base 5 further strengthens the entire device.

[0027] As a preferred embodiment of the present invention, a retractable connecting pipe is installed between the first diverter plate 111 and the second diverter plate 14, and the top of the connecting pipe is fixed at the bottom center of the first diverter plate 111. The retractable connecting pipe installed between the first diverter plate 111 and the second diverter plate 14 enables the spray mechanism to adapt to different heights and maintain the continuity of spraying, thereby improving the flexibility and applicability of the device.

[0028] As a preferred embodiment of the present invention, the connecting pipe includes an outer pipe 12 located outside and an inner pipe 13 located inside, the outer wall of the inner pipe 13 is provided with a limit slide groove 130 slidably connected to the inner wall of the outer pipe 12, and an adjusting knob 120 threadedly connected to the outer wall of the inner pipe 13 is rotatably installed at the end of the outer pipe 12, and the outer wall of the adjusting knob 120 is toothed. The length of the inner pipe 13 extending out of the outer pipe 12 can be adjusted by adjusting the knob 120, thereby changing the range of spraying.

[0029] As a preferred embodiment of the present invention, a second fixing block 121 is fixedly connected to the outer wall of the outer tube 12, a second motor 122 is mounted on the second fixing block 121, and a second driving gear 123 meshing with the adjusting knob 120 is coaxially fixed to the output shaft of the second motor 122. The second driving gear 123 is driven by the second motor 122 to mesh with the adjusting knob 120, thereby realizing automatic adjustment of the length of the connecting tube, further improving the automation and convenience of the device.

[0030] As a preferred embodiment of the present invention, two hydraulic cylinders 3 are symmetrically fixedly connected to the top of the tower body 1, and the piston rods of the two hydraulic cylinders 3 are fixedly connected to the top of the top cover 110. The arrangement of the hydraulic cylinders 3 enables the spray mechanism to automatically move up and down, and the position of the spray mechanism is adjusted according to the needs of exhaust gas treatment, thereby improving the efficiency and flexibility of exhaust gas treatment.

[0031] As a preferred embodiment of the present invention, a conical groove 15 extending to the inside of the bottom support cover 4 is provided at the bottom of the tower body 1. The conical groove 15 at the bottom of the tower body 1 is designed to help collect and discharge the treated liquid, prevent the liquid from accumulating at the bottom of the tower body 1, and ensure the continuity and efficiency of the exhaust gas treatment.

[0032] When the polluted tail gas emission reduction device for sulfuric acid production of the utility model is used, first, after the device is started, the polluted tail gas generated by sulfuric acid production enters the interior of the tower body 1 through the air inlet pipe 6. At this time, the water inlet pipe 2 at the top of the tower body 1 continuously supplies water to the spray mechanism, and the water flows into the top cover 110 through the bellows 10 and is initially diverted through the first diverter plate 111.

[0033] In order to enhance the spraying effect, the first motor 114 is started, and the first driving gear 115 is meshed with the teeth on the first diverter plate 111, driving the first diverter plate 111 to rotate in the top cover 110. This rotation action not only increases the contact area between the spray water and the exhaust gas, but also improves the washing effect of the water on the exhaust gas. At the same time, the diverter net 112 further ensures the uniform distribution of the spray water, so that the harmful substances in the exhaust gas can be more effectively absorbed.

[0034] After washing the tail gas, the spray water reacts with the harmful substances in the tail gas to generate waste water which flows to the bottom of the tower body 1. Here, the design of the conical groove 15 helps to concentrate and discharge the waste water, which is discharged from the device through the drain pipe 7 for subsequent treatment.

[0035] In order to meet the needs of exhaust gas treatment at different heights, the spray mechanism is designed to move up and down. The two hydraulic cylinders 3 are connected to the top of the top cover 110 through piston rods, and the height of the spray mechanism can be adjusted as needed. When the piston rod of the hydraulic cylinder 3 is extended or retracted, the spray mechanism will move up and down accordingly, ensuring that the exhaust gas can be effectively treated at different heights.

[0036] In addition, the connecting pipe between the first splitter plate 111 and the second splitter plate 14 is designed as a retractable structure. The second motor 122 drives the second driving gear 123 to engage with the adjusting knob 120, and the length of the inner tube 13 extending out of the outer tube 12 can be automatically adjusted, thereby changing the spray range. This design not only enhances the flexibility of the device, but also can adjust the spray mode according to actual conditions to achieve the best exhaust gas treatment effect.

[0037] Finally, the clean tail gas after spraying is discharged from the device through the exhaust pipe 8, completing the entire tail gas emission reduction process. In this way, the polluted tail gas emission reduction device for sulfuric acid production of the utility model can effectively reduce the emission of harmful substances in the tail gas and improve environmental protection performance.
