[0002] In the prior art, for example, a utility model with application number 202320703315.7 discloses a spray dust removal and purification device. In order to solve the problem that the current device is not convenient to filter the flue gas through the filter plate before the flue gas enters the spray area, reduce the content of large particles in the flue gas, increase the use time of water, alkali solution and oxidizing liquid, etc., and is not convenient to make the flue gas turbulent and increase the time of flue gas spraying and the uniformity of spraying, the exhaust gas is filtered through the filter plate during use to reduce the content of large particles of dust in the exhaust gas, and enters the spray through the guide door. Spraying is carried out in the box, and the exhaust gas is sprayed and dusted through the first water spray head. The motor drives the first sector gear and the second sector gear to rotate, so that the gears make reciprocating swing motion, and the rotating rod drives the second water spray head to make a swing motion through the gear to spray the exhaust gas, so that the exhaust gas is turbulent and the exhaust gas spraying time is increased, so that the exhaust gas is filtered through the filter plate before entering the spraying area, the content of large particles in the exhaust gas is reduced, the use time of water, alkali solution and oxidizing liquid is increased, and the smoke turbulence is increased, the smoke spraying time and the uniformity of the spraying are increased.

[0003] Similar to the above application, there are still some shortcomings:

[0004] During the spraying process, the uniform spraying inside the box cannot be guaranteed, which affects the purification effect. During the use of the device, in order to ensure the filtering effect, the filter needs to be replaced regularly, which reduces the service life of the filter and the use cost of the equipment;

[0026] General working principle: during spray purification, the exhaust gas enters the interior of the control box 1 through the air inlet 3, and then enters the interior of the spray box 2 after being filtered by the filter 5. At the same time, the rotating motor 8 starts to control the rotation of the hollow tube 6, and the injection mechanism 11 is used to inject the spray liquid into the interior of the hollow tube 6. The spray liquid is discharged from the nozzle 7, and the rotation of the hollow tube 6 drives the continuous rotation of the nozzle 7 to perform turbulence, thereby increasing the contact effect between the exhaust gas and the spray liquid. In addition, during the rotation of the hollow tube 6, the brush plate 9 will be driven to clean the surface of the filter 5 to ensure the permeability of the filter 5 and improve the service life of the filter 5.

[0027] In this embodiment, a collecting box 12 is provided at the inner bottom of the control box 1 and below the brush plate 9 , and a dust removal port is provided at one end of the collecting box 12 .

[0028] Partial working principle: the dust swept from the filter 5 will fall into the interior of the collection box 12 for collection and storage. After a certain amount of dust is collected, the dust removal port is opened for cleaning.

[0029] In this embodiment, a partition 13 is vertically arranged inside the control box 1 , and the air inlet 3 and the collection box 12 are both located between the partition 13 and the filter screen 5 .

[0030] Partial working principle: After the exhaust gas enters the interior of the control box 1 , the gas is effectively blocked due to the obstruction of the partition 13 to prevent the exhaust gas from polluting the control box 1 .

[0031] In this embodiment, a guide cover 23 is fixedly provided at one end of the spray box 2 near the filter 5 . The guide cover 23 is funnel-shaped, and the narrow end of the guide cover 23 is close to the inside of the spray box 2 .

[0032] Partial working principle: During the spraying process, since the narrow end of the guide cover 23 faces the inside of the spray box 2, the spray liquid is prevented from drifting into the inside of the control box 1, and a certain barrier and exhaust gas drainage effect is activated.

[0033] In this embodiment, the liquid injection mechanism 11 includes a transfer chamber 14, a through port 15 and an extraction component. The transfer chamber 14 is fixed inside the control box 1. The hollow tube 6 passes through the interior of the transfer chamber 14 and is rotatably connected to the transfer chamber 14. The hollow tube 6 is located on the side of the interior of the transfer chamber 14 and is evenly provided with a through port 15 along the circumferential direction. An extraction component is provided between the outer side of the transfer chamber 14 and the liquid collecting tank 10.

[0034] Partial working principle: When spraying the spray liquid, first use the extraction component to extract the spray liquid inside the liquid collection box 10, and then send it into the transfer bin 14. The spray liquid passes through the opening 15 and then enters the interior of the hollow tube 6 to spray the spray liquid.

[0035] In this embodiment, the extraction component includes a cylinder body 16, a piston 17, a pull rod 18, a crankshaft 19, a sleeve 20, a drain pipe 21 and a suction pipe 22. The cylinder body 16 is symmetrically fixed at the top and bottom of the control box 1. The piston 17 is slidably installed inside the cylinder body 16. The pull rod 18 is hingedly installed on the side of the piston 17 facing the rotating motor 8. A crankshaft 19 is installed between the output end of the rotating motor 8 and the end of the hollow tube 6. A sleeve 20 is sleeved at the middle position of the crankshaft 19. The outer side of the sleeve 20 is hinged to the end of the pull rod 18. A suction pipe 22 is provided between the cylinder body 16 and the liquid collecting box 10. A drain pipe 21 is provided between the cylinder body 16 and the transfer bin 14. Both the suction pipe 22 and the drain pipe 21 are provided with a one-way valve.

[0036] Local working principle: when the rotating motor 8 controls the rotation of the hollow tube 6, it will drive the crankshaft 19 to rotate. During the rotation of the crankshaft 19, it will control the pull rod 18 to drive the piston 17 to slide, and the liquid inside the liquid collecting box 10 will be injected into the cylinder body 16 through the suction pipe 22. After the piston 17 is reset, the liquid will be injected into the transfer bin 14 through the discharge pipe 21, realizing the automatic circulation of the spray liquid.

[0037] In this embodiment, an impurity filter is provided on the outside of the connection between the liquid extraction pipe 22 and the liquid collection box 10 , and a transparent observation window is provided on the outside of the liquid collection box 10 .

[0038] Partial working principle: During the circulation of the spray liquid, the impurity filter is used to circulate and filter the spray liquid to avoid clogging of the nozzle 7.
