[0014] The present invention provides an adjustable flue gas desulfurization and demisting equipment. It has the following beneficial effects:

[0015] (1) The invention sets an anti-accumulation device. When the smoke flows along the surface of the guide plate, the smoke dust in the smoke will adhere to the inner wall of the guide plate. The motor is turned on, the motor drives the rotating rod to rotate, the rotating rod drives the L-shaped fixed frame to rotate, the L-shaped fixed frame drives the sliding rod to rotate, the sliding rod drives the connecting block to rotate, the connecting block drives the scraper to rotate, and the scraper scrapes the smoke dust on the surface of the guide plate, which not only keeps the surface of the guide plate clean, but also prevents the accumulation of smoke dust from hindering the flow of smoke, ensuring the continuous and efficient operation of the defogger, thereby improving the processing efficiency and stability of the entire defogger, so that the sliding rod can be quickly reset, and the scraper can move up and down while rotating, so that it can contact the surface of the guide plate more deeply and remove the attached smoke dust more effectively. At the same time, the scraper moves up and down while rotating, making the cleaning action more comprehensive without leaving dead angles. This composite movement mode not only further improves the cleaning efficiency, but also ensures the thorough cleaning of the guide plate, thereby maintaining the best working state of the defogger and extending the service life of the equipment.

[0016] (2) The invention sets a stirring device and starts the vacuum pump. The vacuum pump draws the smoke upward through the suction port, then enters the interior of the exhaust pipe through the exhaust port, and is discharged from the bottom end of the exhaust pipe. The bottom end of the exhaust pipe is immersed in the liquid, and the smoke will float upward from the bottom end of the exhaust pipe. The smoke will pass through the liquid, so that the smoke particles in the smoke will be adsorbed and captured by the liquid, which not only reduces the emission of smoke, but also improves the overall cleanliness of the smoke, and improves the demisting and desulfurization efficiency of the defogger on the smoke, so that it knocks on the outer wall of the guide plate. After the interference of the triangular block is released, the wheel is reset by the torsion spring. The floating and knocking of the stirring plate not only promotes the flow of liquid and increases the contact opportunity between the liquid and the smoke particles, thereby improving the dust removal efficiency, but also its knocking action on the outer wall of the guide plate helps to loosen and remove the stubborn smoke attached to the inner wall.

[0027] The anti-accumulation device 2 also includes a spring piece 28, a triangular block 29, a rotating wheel 210, a connecting plate 211 and a triangular resistance block 212. The spring piece 28 is arranged between the L-shaped fixed frame 24 and the bottom of the slide bar 25. The spring piece 28 is elastically arranged.

[0029] When the slide bar 25 rotates, the slide bar 25 drives the triangular block 29 to rotate, and the triangular block 29 contacts the triangular surface of the triangular contact block 212, so that the triangular block 29 drives the slide bar 25 to move downward, and the slide bar 25 drives the connecting block 26 to move downward, and the connecting block 26 drives the scraper 27 to move downward.

At the same time, the scraper 27 moves up and down while rotating, so that the cleaning action is more comprehensive without dead angles. This composite movement mode not only further improves the cleaning efficiency, but also ensures the thorough cleaning of the guide plate 21, thereby maintaining the best working state of the defogger 1 and extending the service life of the equipment.

[0030] See also Figure 6-Figure 7 On the basis of the above embodiment, in another embodiment of the present invention, the stirring device 3 includes an air pump 31, a suction port 32, an exhaust port 33 and an exhaust pipe 34. The air pump 31 is fixedly installed on the top of the guide plate 21. The outer wall of the air pump 31 is provided with a high temperature resistant material. Most of the smoke and dust adhere to the surface of the guide plate 21, but a small part of the smoke and dust will float upward with the smoke. The liquid is added between the guide plate 21 and the inner wall of the defogger 1 through the water inlet pipe 14, and the air pump 31 is turned on. The suction port 32 is fixedly installed at the bottom of the air pump 31. The air pump 31 sucks the smoke upward through the suction port 32.

The bottom end of the exhaust pipe 34 is immersed in the liquid. The flue gas will float upward from the bottom end of the exhaust pipe 34. The flue gas will pass through the liquid, so that the smoke particles in the flue gas will be adsorbed and captured by the liquid, which not only reduces the emission of smoke dust, but also improves the overall cleanliness of the flue gas, and improves the demisting and desulfurization efficiency of the defogger 1 on the flue gas.

[0031] The stirring device 3 also includes an L-shaped stirring rod 35 and a stirring plate 36. The top end of the L-shaped stirring rod 35 is fixedly mounted on the outer side of the rotating wheel 210 near the outer wall of the guide plate 21. The number of L-shaped stirring rods 35 is several. When the triangular block 29 contacts the triangular contact block 212, the triangular contact block 212 will drive the connecting plate 211 to rotate upward on the inner wall of the rotating hole of the guide plate 21 with the rotating wheel 210 as the center of the circle. The rotating wheel 210 drives the L-shaped stirring rod 35 to rotate downward. The stirring plates 36 are fixedly mounted on both sides of the L-shaped stirring rod 35. The number of stirring plates 36 is several, and the stirring plates 36 and the guide plates 21, the L-shaped stirring rod 35 drives the stirring plate 36 to rotate downward, and the stirring plate 36 pushes and fans the liquid on the outer wall of the guide plate 21. At the same time, the stirring plate 36 contacts the outer wall of the guide plate 21, so that it knocks on the outer wall of the guide plate 21. After the resistance of the triangular block 29 is released, the runner 210 is reset by the torsion spring. The floating and knocking of the stirring plate 36 not only promotes the flow of liquid and increases the contact opportunity between the liquid and the smoke particles, thereby improving the dust removal efficiency, but also its knocking action on the outer wall of the guide plate 21 helps to loosen and remove the stubborn smoke attached to the inner wall.

[0032] When this embodiment is working, most of the smoke and dust adheres to the surface of the guide plate 21, but a small part of the smoke and dust will float upward with the smoke. Liquid is added between the guide plate 21 and the inner wall of the defogger 1 through the water inlet pipe 14, and the vacuum pump 31 is turned on. The vacuum pump 31 draws the smoke upward through the suction port 32, and then enters the interior of the exhaust pipe 34 through the exhaust port 33, and is then discharged from the bottom end of the exhaust pipe 34. The bottom end of the exhaust pipe 34 is immersed in the liquid, and the smoke will float upward from the bottom end of the exhaust pipe 34. The smoke will pass through the liquid, so that the smoke particles in the smoke will be adsorbed and captured by the liquid, which not only reduces the emission of smoke and dust, but also improves the overall cleanliness of the smoke, and improves the defogger 1 The efficiency of flue gas demisting and desulfurization.

[0033] When the triangular block 29 hits the triangular resistance block 212, the triangular resistance block 212 will drive the connecting plate 211 to rotate upward on the inner wall of the rotating hole of the guide plate 21 with the rotating wheel 210 as the center, and the rotating wheel 210 drives the L-shaped stirring rod 35 to rotate downward, and the L-shaped stirring rod 35 drives the stirring plate 36 to rotate downward, and the stirring plate 36 pushes and fans the liquid on the outer wall of the guide plate 21. At the same time, the stirring plate 36 contacts the outer wall of the guide plate 21, so that it knocks on the outer wall of the guide plate 21. After the resistance of the triangular block 29 is released, the rotating wheel 210 is reset by the torsion spring. The floating and knocking of the stirring plate 36 not only promotes the flow of liquid, increases the contact opportunity between liquid and smoke particles, thereby improving the dust removal efficiency, but also its knocking action on the outer wall of the guide plate 21 helps to loosen and remove stubborn smoke attached to the inner wall.
