There are two rotating motors 212, and crushing tooth knife assemblies 213 are fixedly installed on the output shafts of the two rotating motors 212. By controlling the rotating motor 212 to start, the crushing tooth knife assemblies 213 can perform preliminary crushing on the solid desulfurizer, so that the desulfurizer can be discharged at a relatively uniform speed, and blockage during discharge can be effectively avoided. One end of the output shaft of the rotating motor 212 is fixedly connected to a transmission assembly 214, and the output end of the transmission assembly 214 is fixedly connected to a crushing and discharging flap 215. The transmission assembly 214 is connected and rotated, and the crushing and discharging flap 215 is rotated under the linkage action of the belt, so that the desulfurizer can evenly enter the fine grinding unit below.

[0023] Example 2 like Figure 1-8 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the auxiliary vibration unit includes a guide inclined plate 221 and a second rotating motor 222, one end of the guide inclined plate 221 is fixedly connected to the inner wall of the desulfurizer supply box 211 by bolts, the second rotating motor 222 is fixedly installed on the outer surface of the desulfurizer supply box 211, and a connecting shaft is fixedly installed on the output shaft of the second rotating motor 222, the outer surface of the connecting shaft is rotatably connected to the inner walls of both sides of the desulfurizer supply box 211, and two groups of rotating cams 2221 of different sizes are fixedly installed on the outer surface of the connecting shaft; The protrusions of the two sets of rotating cams 2221 are staggered with each other; The guide inclined plates 221 are staggered on the sides close to each other, and the inner end of one guide inclined plate 221 extends below the other fast guide inclined plate 221, and there is a gap between the two guide inclined plates 221 for feeding the crushed desulfurizer; The two guide inclined plates 221 are both provided with a material blocking convex strip 2211 above, and the upper surface of the material blocking convex strip 2211 is inclined downward by 5-15 degrees. The control of the rotating motor 222 is turned on, so that its output shaft rotates to provide power output for the rotation of the connecting shaft, so that the rotating cam 2221 rotates synchronously. The two guide inclined plates 221 are staggered and there is a gap. The size of the gap can be adjusted according to actual conditions so that the fully crushed desulfurizer can be discharged from the gap. The material blocking convex strips 2211 are provided to play a certain blocking role. Large pieces of desulfurizer are temporarily blocked on the material blocking convex strips 2211. Since the guide inclined plate 221 is in a vibrating state during operation, the vibration of the guide inclined plate 221 can rebound the large pieces of desulfurizer from the guide inclined plate 221 to the upper preliminary crushing unit for further crushing. The completely crushed desulfurizer can enter the lower layer through the gap. At the same time, the vibration effectively avoids the blockage problem caused by excessive accumulation of the desulfurizer during the sliding process on the guide inclined plate 221. The auxiliary vibration unit also includes an arc-shaped hollow pushing plate 223, one end of which is slidably connected to the inner wall of a movable groove preset on the inner side wall of the desulfurizer supply box 211, and a contact telescopic spring strip 224 is fixedly installed at the lower end of the arc-shaped hollow pushing plate 223, and the other end of the contact telescopic spring strip 224 is fixedly connected to the inner cavity bottom surface of the movable groove, and a hollow inner cavity 2231 is provided on the inner side surface of the arc-shaped hollow pushing plate 223, and a reciprocating elastic wire 2232 is fixedly installed on the inner cavity bottom surface of the hollow inner cavity 2231, and a knocking ball 2233 is hinged at the other end of the reciprocating elastic wire 2232, and the outer surface of the knocking ball 2233 is movable with the inner cavity bottom surface of the hollow inner cavity 2231. The upper end of the arc hollow pushing plate 223 is in contact with the guide inclined plate 221. Since the desulfurizer is easy to stick together, the vibration and knocking action of the knocking ball 2233 can effectively break up the material particles, ensuring that the material inside the desulfurizer supply box is not easily blocked. Under the reciprocating knocking action of the rotating cam 2221 on the arc hollow pushing plate 223, the reciprocating elastic wire 2232 is continuously contracted by the transmission of external force, and the elasticity generated drives the knocking ball 2233 to shake, thereby realizing the reciprocating knocking of the top of the inner cavity of the hollow inner cavity 2231, ensuring that the knocking force is transmitted to the lower end of the guide inclined plate 221, enhancing the shaking-off speed of the desulfurizer on the surface of the guide inclined plate 221, and realizing uniform material dropping; The fine grinding unit includes a guide plate 231 and a rotating motor 233. The guide plate 231 is fixedly mounted on the bottom surface of the inner cavity of the desulfurizer supply box 211. A guide hole 232 is provided on the central inner surface of the guide plate 231. The guide plate 231 is a hollow structure. The upper surface of the guide plate 231 is made of steel plate. Both sides of the upper surface of the guide plate 231 are provided with protrusions 2311. The protrusions 2311 are located directly below the two rotating cams 2221. When the rotating cams 2221 rotate, they touch the protrusions 2311, causing the guide plate 231 to vibrate. The rotating motor 233 is fixedly mounted on the outer surface of the lower end of the grinding box 2111. A rotating rod is fixedly mounted on the output shaft of the rotating motor 233. A conical grinding pestle plate 234 is fixedly installed on the outer surface of the end, and a reinforcing rib plate 234 is evenly added to the outer surface of the conical grinding pestle plate 234. A connecting sleeve 235 is fixedly installed on the outer surface of the lower end of the rotating rod, and a turning claw 2351 is fixedly installed on the outer surface of the connecting sleeve 235. Under the driving setting of the rotating motor 222, the rotating cam 2221 rotates synchronously to repeatedly knock the arc-shaped hollow pushing plate 223, and the abutting telescopic spring strip 224 is compressed and deformed, which can reset the arc-shaped hollow pushing plate 223 as a whole, ensuring that the upper arc surface of the arc-shaped hollow pushing plate 223 is repeatedly abutted against the lower end of the guide inclined plate 221, thereby enhancing the effective shaking off of the desulfurizer scattered on the surface of the guide inclined plate 221.

[0024] The rotation of the rotating cam 2221 can synchronously touch the protrusion 2311, thereby causing the guide plate 231 to vibrate. The vibration of the guide plate 231 can make the crushed desulfurizer more evenly distributed on the guide plate 231. At the same time, the lower surface of the guide plate 231 is in contact with the conical grinding pestle plate 234. When the guide plate 231 vibrates, the vibration will be transmitted to the conical grinding pestle plate 234, causing the conical grinding pestle plate 234 to vibrate, thereby preventing the desulfurizer from adhering to the surface of the conical grinding pestle plate 234 during the use of the conical grinding pestle plate 234.

Under the action of the annular spray pipe 323 and the atomizing nozzles, dual mixing of liquid and atmospheric gas, as well as solid desulfurizer gas and atmospheric gas is achieved, thereby enhancing the rate and quality of atmospheric desulfurization. The air guide filtering unit also includes a dust filter screen plate 324, a circulating air guide row plate 325 and an adsorption core plate 326. The dust filter screen plate 324, the circulating air guide row plate 325 and the adsorption core plate 326 are all fixedly installed on the upper inner wall of the desulfurization tower 1, and the dust filter screen plate 324, the circulating air guide row plate 325 and the adsorption core plate 326 are arranged from bottom to top in sequence. The dust filter screen plate 324, the circulating air guide row plate 325 and the adsorption core plate 326 cooperate with each other to ensure that the impurities and dust in the desulfurized gas are fully filtered during the discharge process to prevent the exhaust pipe 11 from being blocked, thereby improving the integrity of the atmospheric desulfurization equipment of the invention.

[0026] The following is a detailed description of the usage of the atmospheric desulfurization equipment used in environmental protection projects.

[0027] like Figure 1-8 As shown, during operation, first, the atmospheric gas is introduced into the interior of the desulfurization tower 1 through the air inlet hopper connected to one side of the desulfurization tower 1, and then the valve is closed. At this time, the user controls the rotary motor 212 to start, so that the crushing toothed cutter assembly 213 performs preliminary crushing on the solid desulfurizer, which can realize the desulfurizer discharge operation at a relatively uniform speed, effectively avoiding the blockage during discharge. Through the connection and rotation of the transmission assembly 214, the crushing and shifting flap 215 is rotated under the linkage action of the belt, so that the desulfurizer can be uniformly introduced into the fine grinding unit below; Furthermore, the guide inclined plate 221 is provided to guide the desulfurizer flipped back and forth by the crushing and shifting flap 215. Under the driving setting of the rotating motor 222, the rotating cam 2221 rotates synchronously to repeatedly and staggeredly knock the arc-shaped hollow pushing plate 223, and the abutting telescopic spring strip 224 is compressed and deformed, so that the arc-shaped hollow pushing plate 223 can be reset as a whole, ensuring that the upper end arc surface of the arc-shaped hollow pushing plate 223 repeatedly abuts against the lower end of the guide inclined plate 221, thereby enhancing The desulfurizer scattered on the surface of the guide inclined plate 221 is effectively shaken off. Under the reciprocating knocking action of the rotating cam 2221 on the arc-shaped hollow pushing plate 223, the reciprocating elastic wire 2232 is continuously contracted by the transmission of external force, and the elasticity generated drives the knocking ball 2233 to shake, thereby realizing the reciprocating knocking of the top of the inner cavity of the hollow inner cavity 2231, ensuring that the knocking force is transmitted to the lower end of the guide inclined plate 221, enhancing the shaking-off speed of the desulfurizer on the surface of the guide inclined plate 221, and realizing uniform material dropping; The guide plate 231 cooperates with the guide hole 232 to guide the initially crushed desulfurizer, and the desulfurizer that intersects the lower side of the guide hole 232 and the upper end of the conical grinding pestle plate 234 is continuously ground with the continuous rotation of the conical grinding pestle plate 234.

In addition, The gas in the desulfurizer is effectively guided to the interior of the desulfurization tower 1. Under the action of the annular spray pipe 323 and the atomizing nozzle, dual mixing of liquid and atmospheric gas, as well as solid desulfurizer gas and atmospheric gas is achieved, thereby enhancing the rate and quality of atmospheric desulfurization. Finally, the desulfurized gas cooperates with the dust filter screen 324, the circulating air guide plate 325 and the adsorption core plate 326 to ensure that the impurities and dust in the desulfurized gas are fully filtered during the discharge process, and finally discharged through the smoke exhaust pipe 11 and the air pump 12.
