Embodiment 1

[0020] As Figures 1-5 shown, a high-efficiency soot blowing device for an SCR denitration reactor described in this embodiment includes a fuselage 1, a first box door 2 hermetically arranged at the front of the fuselage 1, a fan 4 fixedly installed on the left side of the fuselage 1 through a mounting plate, a treatment box 7 fixedly installed on the right side of the fuselage 1, a catalyst layer 6 arranged inside the fuselage 1, an air disk 5 fixedly installed inside the fuselage 1 through a mounting column, a motor 8 fixedly installed on the left side of the fuselage 1 through a mounting plate, and a connection component 3 arranged inside the fuselage 1. The connection component 3 includes a cleaning mechanism 31 arranged inside the fuselage 1, and a dust removal mechanism 32 arranged on the right side of the fuselage 1. The output end of the fan 4 is communicated with the air disk 5 through an air duct. The cleaning mechanism 31 includes a lead screw 311 fixedly connected to the output end of the motor 8. A mounting block 312 is threadedly connected to the outer wall of the lead screw 311. A mounting frame 313 is arranged at the bottom of the mounting block 312. A connecting rod 314 is fixedly connected to the side wall of the mounting block 312. A sliding rod 315 is fixedly connected to the inner wall of the fuselage 1. A rotating shaft 316 is rotatably connected to the inside of the mounting frame 313 through a bearing. A cleaning roller 317 is fixedly connected to the outer wall of the rotating shaft 316. A gear 318 is fixedly connected to one end of the rotating shaft 316. A rack 319 is fixedly connected to the inner wall of the fuselage 1. A positioning groove 3110 is formed at the bottom of the mounting block 312. A positioning block 3111 is clamped to the inner wall of the positioning groove 3110. A groove 3112 is formed in the inner wall of the positioning groove 3110. A clamping block 3113 is clamped to the inner wall of the groove 3112. A first card slot 3114 is formed on the outside of the positioning block 3111. A rotating rod 3115 is rotatably connected to one side of the mounting block 312 through a bearing. One end of the rotating rod 3115 is movably connected to a clamping rod 3116. A limiting block is fixedly connected to the outer end of the clamping rod 3116. A spring 3117 is fixedly connected to the outside of the rotating rod 3115. A second card slot 3118 is formed on one side of the mounting block 312.

[0021] In this embodiment, the lead screw 311 is rotatably connected to the fuselage 1 through a bearing. There are two mounting blocks 312, which are symmetrically distributed inside the fuselage 1, and one side of the mounting block 312 is slidably connected to the outer wall of the slide bar 315. The gear 318 is meshed with the rack 319. Through the cooperation of the lead screw 311, the mounting block 312, the gear 318, the rack 319, and the mounting frame 313, the cleaning roller 317 can rotate during the left and right movement, so that the cleaning roller 317 can achieve a better cleaning effect on the catalyst layer 6.

[0022] Further, the clamping rod 3116 is clamped with the first clamping groove 3114. One end of the spring 3117 away from the rotating rod 3115 is fixedly connected to the limiting block, and the clamping block 3113 is fixedly connected to the positioning block 3111. Through the cooperation of the positioning block 3111, the positioning groove 3110, the groove 3112, the clamping block 3113, the rotating rod 3115, the clamping rod 3116, the spring 3117, and the first clamping groove 3114, it is convenient for manual disassembly of the mounting frame 313, so as to facilitate manual cleaning of the cleaning roller 317 arranged inside the mounting frame 313, and thus the cleaning effect of the cleaning roller 317 can be better.

[0023] Furthermore, the second clamping groove 3118 is clamped with the clamping rod 3116, and the bottom of the positioning block 3111 is fixedly connected to the mounting frame 313. Through the second clamping groove 3118 and the clamping rod 3116, the rotating rod 3115 can stay outside away from the positioning block 3111, so that the operator can free up his hands, and it is more convenient for the operator to disassemble and assemble the mounting frame 313.

[0024] When the catalyst layer 6 needs to be cleaned, the catalyst layer 6 can be blown away by the fan 4 and the air disk 5, and then the motor 8 drives the screw rod 311 to rotate back and forth. Since the two mounting blocks 312 are fixedly connected by the connecting rod 314, and one of the mounting blocks 312 is slidably connected to the outer wall of the sliding rod 315, the mounting block 312 threadedly connected to the outer wall of the screw rod 311 can be moved by rotating the screw rod 311, and then the mounting frame 313 set at the lower part of the mounting block 312 can be moved synchronously. By moving the mounting frame 313, the cleaning roller 317 can be moved synchronously, and the gear 318 and the rack 319 can move relative to each other, so that the cleaning roller 317 can rotate during the left and right movement, so that the cleaning roller 317 can have a better cleaning effect on the catalyst layer 6. Further, when the mounting frame 313 needs to be disassembled, When the user wants to remove the cleaning roller 317 from the cleaning roller 318, the cleaning roller 318 can be easily removed from the cleaning roller 318 by manually removing the cleaning roller 318 from the cleaning roller 318. Example 2

[0025] like Figures 1 to 5 As shown, on the basis of Example 1, in the high-efficiency soot blowing device for the SCR denitrification reactor described in this embodiment, the dust removal mechanism 32 includes an absorption pipe 321 connected to the left side of the processing box 7, the absorption pipe 321 is connected to an absorption head 322 at one end away from the processing box 7, a collecting box 323 is arranged inside the processing box 7, a second box door is sealed at the front of the processing box 7, a processing pipe 324 is connected to the right side of the processing box 7, a filter plate 325 is detachably connected to the inside of the processing pipe 324, a connecting pipe 326 is connected to the right side of the processing pipe 324, and an air suction pump 327 is fixedly installed on the right side of the processing box 7 through a mounting plate.

[0026] In this embodiment, one end of the connecting pipe 326 is connected to the input end of the suction pump 327. Through the cooperation of the absorption pipe 321, the absorption head 322, the suction pump 327, the processing box 7, the processing pipe 324, the filter plate 325, and the connecting pipe 326, the dust generated during the soot blowing process can be filtered to prevent the dust from being discharged and affecting the external environment.

[0027] When performing the soot blowing operation, through the cooperation of the suction pump 327, the connecting pipe 326, and the processing pipe 324, a negative pressure can be generated in the processing box 7. Under the action of the absorption pipe 321 and the absorption head 322, the dust generated during the soot blowing process in the fuselage 1 can be absorbed into the processing box 7. When the washed dust enters the processing box 7, under the action of gravity, the larger dust impurities will fall into the collection box 323. Subsequently, the smaller dust and other impurities will be absorbed into the processing pipe 324 and can be further processed through the filter plate 325, thereby achieving the dust removal effect.
