[0033] Specifically, a water reservoir is provided at the bottom of the cavity inside the shell 1, and lime water for desulfurization is stored in the water reservoir. The spray head 7 sprays the lime water in the form of water mist, thereby expanding the contact area between the lime water and the flue gas, thereby increasing the reaction rate between the flue gas and the lime water, and improving the quality of desulfurization. The collection basket 15 is used to collect particulate matter generated after desulfurization, and the inclined sieve plate 5 will uniformly pour the particulate matter into the collection basket 15. The top cover outside the collection basket 15 is used to prevent the flue gas from leaking, and the particulate matter falling into the collection basket 15 can be recovered by opening the top cover.

[0034] Refer to 3 and Figure 4The gear set includes a gear 10 and an incomplete gear 9, the front side of the gear 10 is fixedly connected to the rear end of the rotating shaft 4, the incomplete gear 9 is meshedly connected to the top of the gear 10, and the front side of the incomplete gear 9 is rotatably connected to the rear side of the outer wall of the housing 1; the transmission assembly includes two pulleys 8, the front side of one pulley 8 is fixedly connected to the rear end of the rotating rod 2, and the front side of the other pulley 8 is fixedly connected to the rear side of the incomplete gear 9, and the two pulleys 8 are connected by a belt;

[0035] Specifically, the incomplete gear 9 is used to indirectly drive the gear 10, and rotate the gear 10 at a certain angle, so that the rotating shaft 4 connected to the gear 10 rotates, and the screen plate 5 connected to the rotating shaft 4 tilts, so that the particles falling on the screen plate 5 fall into the collection basket 15 under the action of the inclined surface. After the smoke enters the cavity, it will drive the impeller 3 to rotate through the upper part of the cavity, and the impeller 3 will drive the rotating rod 2 to rotate counterclockwise. The rotating rotating rod 2 drives the pulley 8 at the top to rotate, and drives the pulley 8 at the bottom to rotate through the belt, and the pulley 8 at the bottom drives the incomplete gear 9 to rotate.

[0036] Reference Figure 2 and Figure 5 The reset assembly includes a fixed rod 11 and a connecting member 14. The fixed rod 11 is arranged on the bottom side of the rotating shaft 4. The front and rear ends of the fixed rod 11 are fixedly connected to the inner wall of the housing 1. The middle end of the outer wall of the fixed rod 11 is sleeved with a torsion spring 12.

One end of the torsion spring 12 abuts on the right side of the fixing member 13, and the other end of the torsion spring 12 is fixedly connected to the bottom end of the connecting member 14.

[0037] Specifically, the fixing member 13 is used to press against one end of the torsion spring 12, so that when the other end of the torsion spring 12 is subjected to force, the torsion spring 12 is prevented from rotating on the fixing rod 11, so that when the other end of the torsion spring 12 is subjected to force, the torsion spring 12 is forced to deform by pressing against one end of the fixing member 13 and generating an elastic force for resetting. When the sieve plate 5 tilts to the right, the other end of the torsion spring 12 is pressed down by the connecting member 14 fixed to the bottom side of the sieve plate 5. When the other end of the torsion spring 12 loses force, the elasticity generates a thrust, pushing the connecting member 14 to push the sieve plate 5 upward, so that the sieve plate 5 is reset.

[0038] Reference Figure 2 and Figure 3 The delivery assembly includes a water pump 17, which is arranged at the rear bottom end of the housing 1, the input end of the water pump 17 is connected to the output end of the water outlet 16 through a pipe 1, and the output end of the water pump 17 is connected to the input end of the water delivery pipe 6 through a pipe box 2;

[0039] Specifically, when lime water is transported to the water pipe 6, the input end of the started water pump 17 generates gravity, and the lime water in the water tank at the bottom of the cavity flows from the water outlet 16 to the pipe 1 and the water pump 17 in turn. The water pump 17 guides the lime water into the pipe 2, and then enters the water pipe 6 from the pipe 2. The water pipe 6 transports the lime water to each sprinkler head 7.

[0040] Working principle: During desulfurization, the flue gas enters the cavity of the shell 1 from the air inlet 18, and the flue gas follows the top of the cavity to the middle end of the cavity, and the water pump 17 is started. The input end of the water pump 17 generates gravity, and the lime water in the water reservoir at the bottom of the cavity is successively from the water outlet 16 to the pipe 1 and the water pump 17, and the lime water is introduced into the pipe 2 by the water pump 17, and then enters the water pipe 6 from the pipe 2, and the lime water is transported to each spray head 7 by the water pipe 6, and the lime water is sprayed from the spray head 7. The sprayed lime water desulfurizes the flue gas, and the particles generated by the reaction of the flue gas and the lime water fall onto the sieve plate 5 on the bottom side, and the excess incompletely reacted lime water passes through the sieve plate 5 and falls back into the water reservoir, and the desulfurized flue gas is discharged from the air outlet 19. After the flue gas enters the cavity, it will drive the impeller 3 to rotate when passing through the top of the cavity, and at the same time, the impeller 3 drives the rotating rod 2 to rotate counterclockwise, and the rotating The rod 2 drives the pulley 8 at the top to rotate, and drives the pulley 8 at the bottom to rotate through the belt, and the pulley 8 at the lower end drives the incomplete gear 9 to rotate, and the rotating incomplete gear 9 indirectly meshes with the gear 10, so that the gear 10 rotates to a certain extent, driving the rotating shaft 4 connected to the gear 10 together with the sieve plate 5 to rotate to the right with the rotating shaft 4 as the center, so that the sieve plate 5 tilts to the right, and presses the other end of the torsion spring 12 down through the connecting piece 14 fixed on the bottom side of the sieve plate 5, and the particles on the sieve plate 5 tilted to the right will fall into the left end opening of the collecting basket 15 along the inclined surface, and thus fall into the collecting basket 15. When the incomplete gear 9 no longer meshes with the gear 10, the other end of the torsion spring 12 pressed down loses the force and elastically resets, pushing the connecting piece 14 to push the sieve plate 5 upward, so that the sieve plate 5 is reset, thereby collecting the particles on the sieve plate 5 in a unified manner.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
