[0025] The atomizing dust removal part 3 specifically includes: a water storage tank 311, fixedly mounted on the left outer wall of the box body 1; a ventilation pipe 319, connected and arranged at the top of the box body 1; a hydraulic valve 312 is fixedly mounted on the top of the water storage tank 311, and a water pipe is arranged to connect the hydraulic valve 312 and the water storage tank 311;

[0026] A motor 318 is fixedly installed on the top of the ventilation pipe 319, and ventilation holes are evenly spaced around the top of the ventilation pipe 319. A round rod is fixedly connected to the motor 318, and the other end of the round rod movably passes through the top of the ventilation pipe 319 and extends to the inside of the ventilation pipe 319, and fan blades 316 are evenly spaced and fixedly installed on the outer wall of the round rod.

[0027] An annular water pipe 317 is provided on the top of the ventilation pipe 319, and atomizing nozzles 315 are equidistantly connected to the annular water pipe 317, and the annular water pipe 317 is connected to the hydraulic valve 312 through a water pipe. The bottom end of the atomizing nozzle 315 is fixedly connected to a support rod, and the other end of the support rod is fixedly connected to a wind net 313, and an atomizing fan 314 is movably installed on the outer wall of the support rod.

[0028] In the process of this embodiment, the device is first placed below the bio-block discharge port, and then, according to the size of the dust during discharge, the hydraulic valve 312 is adjusted to control the pressure of the water mist sprayed by the atomizing nozzle 315 to drive the rotation speed of the atomizing fan 314, so that the water mist is evenly diffused to achieve the effect of dust reduction. Secondly, the motor 318 is started to drive the fan blades 316 to rotate, further diffuse the water mist, increase the contact area between the water mist and the dust, and achieve a better dust reduction effect. Example

[0029] Based on Example 1, a preferred embodiment of a dust removal device for biomass briquetting provided by the present invention is as follows: Figure 1-4 As shown: the screening part 4 specifically includes: a screen plate 411, fixedly mounted on the inner wall of the box body 1; a first roller group 412, fixedly mounted inside the box body 1; a second roller group 414, arranged below the first roller group 412; exhaust screen holes 413, circumferentially equidistantly arranged on the right inner wall of the box body 1; and an electric telescopic rod 416, fixedly mounted on the right inner wall of the box body 1.

[0030] Rollers are movably mounted on the first roller group 412 and the second roller group 414 at equal intervals, and intervals are left between the rollers.

[0031] A telescopic rod 417 is fixedly installed below the electric telescopic rod 416, and a fixed block 418 is fixedly installed at the telescopic end of the telescopic rod 417. The telescopic end of the electric telescopic rod 416 is movably connected to a dust removal shovel 415, and the dust removal shovel 415 is movably connected to the fixed block 418 through a circular shaft.

[0032] During the process of this embodiment, when the biological blocks pass through the first roller group 412 and the second roller group 414, because there is a gap between the rollers on the first roller group 412 and the second roller group 414, some residues and debris on the biological blocks can be filtered down to the bottom of the box 1 when the biological blocks roll, and then the electric telescopic rod 416 is started to drive the telescopic rod 417 to push the fixed block 418 and the ash shovel 415 to push the dust and debris to the outside of the box 1 through the dust removal port. Because the electric telescopic rod 416 is fixedly connected to the top of the ash shovel 415, and because the ash shovel 415 and the fixed block 418 are movably connected, when the electric telescopic rod 416 is contracted, the ash shovel 415 will lift the shovel head, so that dust and debris will not be brought into the interior of the box 1, so that the dust and debris can be better cleaned, and the dust accumulation problem inside the box 1 will not be caused, thereby weakening the dust removal effect.

[0033] Working principle: first, the device is placed below the discharge port of the biomass briquette. Then, according to the size of the dust during discharge, the hydraulic valve 312 is adjusted to control the pressure of the water mist sprayed by the atomizing nozzle 315 to drive the rotation speed of the atomizing fan 314, so that the water mist is evenly diffused to achieve the effect of dust reduction. Then, the motor 318 is started to drive the fan blades 316 to rotate, further diffuse the water mist, increase the contact area between the water mist and the dust, and achieve a better dust reduction effect. Next, when the biomass briquette passes through the first roller group 412 and the second roller group 414, because there is a gap between the rollers on the first roller group 412 and the second roller group 414, the biomass briquette can be rolled when it is In order to filter out some residues and debris on the biological blocks to the bottom of the box body 1, and then start the electric telescopic rod 416 to drive the telescopic rod 417 to push the fixed block 418 and the ash shovel 415 to push the dust and debris to the outside of the box body 1 through the dust removal port. Because the electric telescopic rod 416 is fixedly connected to the top of the ash shovel 415, and because the ash shovel 415 and the fixed block 418 are movably connected, when the electric telescopic rod 416 contracts, the ash shovel 415 will lift the shovel head, and will not bring dust and debris into the interior of the box body 1, so that the dust and debris can be better cleaned, and the problem of dust accumulation inside the box body 1 will not be caused, thereby weakening the dust removal effect.
