They have advantages such as high calorific value, environmental friendliness, and ease of transportation and storage. They have high combustion efficiency, produce few pollutants, and meet environmental protection requirements. Wood biomass pellets are widely used in home heating, industrial boilers, biomass power generation, and other fields, and are a renewable and clean energy source.
[0003] In the process of processing raw materials into biomass pellets, steps such as crushing, drying, and compression are usually required. During these steps, the raw materials are further refined, generating more dust.

[0018] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a wood biomass pellet dust removal device with high-efficiency dust removal function, including a workbench 1, a top cover 2, and a mesh plate 3. The top of the workbench 1 is covered by the top cover 2, and the mesh plate 3 is fixedly installed on the top of the workbench 1. A drain valve 4 is connected to the bottom of the left side of the workbench 1. A water injection mechanism is provided on the left side of the workbench 1, and an air suction mechanism is provided on the front of the workbench 1. A dust removal mechanism is provided inside the workbench 1. Water is automatically injected into the inside of the workbench 1 through the water injection mechanism. The wood biomass pellets are placed on the mesh plate 3, and then the top cover 2 is closed on the top of the workbench 1. The air suction mechanism generates suction inside the workbench 1 to suck up the dust on the wood biomass pellets and bring it into the inside of the workbench 1. The dust removal mechanism can splash water inside the workbench 1 to capture the dust and make it settle at the bottom of the workbench 1. The top cover 2 is opened to remove the wood biomass pellets from the mesh plate 3, and then the drain valve 4 is opened to allow the settled dust to be discharged from the inside of the workbench 1 along with the water.
[0019] The dust removal mechanism includes a rotating shaft 5, a water wheel 6, and a guide plate 7. The rotating shaft 5 is rotatably connected inside the workbench 1, and the water wheel 6 is fixedly connected to the outside of the rotating shaft 5. The guide plate 7 is fixedly connected inside the workbench 1. The bottom of the water wheel 6 is in contact with the water surface inside the workbench 1. A motor 9 is fixedly connected to the right side of the workbench 1. The output end of the motor 9 is fixedly connected to one end of the rotating shaft 5. There are two guide plates 7, distributed at the top and bottom of the water wheel 6. The water wheel 6 is fixed to the rotating shaft 5 as one unit. One end of the rotating shaft 5 is connected to the output end of the motor 9. The motor 9 can drive the water wheel 6 to rotate at high speed inside the workbench 1, so that the water wheel 6 continuously hits the liquid surface to generate water splashes. After the dust-laden gas passes through the water splashes, it can capture dust and guide it to settle at the bottom of the workbench 1 through the guide plate 7, thereby removing dust from the wood biomass particles.
[0020] The air intake mechanism includes a fan 10, an exhaust pipe 11, an air collection pipe 12, and branch pipes 13. The fan 10 is fixedly installed on the right side of the workbench 1. The output end of the fan 10 is connected to the exhaust pipe 11, and the input end of the fan 10 is connected to the air collection pipe 12. One side of the air collection pipe 12 is connected to multiple branch pipes 13. One end of the branch pipe 13 is inserted into the top of the front of the workbench 1. The fan 10 draws air from inside the workbench 1 through the air collection pipe 12 and the branch pipes 13, and discharges it to the outside through the exhaust pipe 11, so that the inside of the workbench 1 is in a negative pressure state. Through the action of air pressure difference, suction is generated inside the workbench 1 to suck up the dust on the wood biomass pellets. The dust enters the inside of the workbench 1 through the holes on the mesh plate 3.
[0021] A sealing plate 14 is detachably connected to the top of the front of the workbench 1 by bolts. A demister 8 is fixedly installed inside the upper part of the workbench 1 and is located below the insertion end of the branch pipe 13. The bolts on the sealing plate 14 are unscrewed, and the demister 8 is installed below the branch pipe 13. Then, the sealing plate 14 is fixed to the top of the front of the workbench 1 by bolts. Gas can only be discharged to the outside by passing through the demister 8. The demister 8 can intercept the water vapor carried by the gas. The water vapor directly hits the blades or wire mesh surface of the demister 8, is captured and attached, and larger droplets naturally settle back into the interior of the workbench 1 under the action of gravity.
[0022] The water injection mechanism includes a water pump 16 and a water inlet pipe 17. The water pump 16 is fixedly installed on the left side of the workbench 1. The output end of the water pump 16 is connected to the left side of the workbench 1. The input end of the water pump 16 is connected to the water inlet pipe 17. The water inlet pipe 17 is connected to an external water source through a water pipe. The water pump 16, the water inlet pipe 17 and the water pipe work together to automatically deliver water into the interior of the workbench 1.
[0023] A liquid level detector 15 is fixedly installed on one side inside the workbench 1. The bottom of the liquid level detector 15 is flush with the bottom of the water wheel 6. The liquid level detector 15 is equipped with a photosensitive receiver and a near-infrared light-emitting diode. It detects the water level by means of light refraction and reflection. When the water level is lower than a preset threshold, the liquid level detector 15 sends a water shortage signal to the controller. After receiving the signal, the controller starts the water pump 16 to pump water from an external water storage container or water source to replenish the water in the workbench 1. During the water replenishment process, the liquid level detector 15 continuously monitors the water level. Once the water level returns to the preset height, it sends a "full water" signal to the controller. After receiving the "full water" signal, the controller stops the water pump to replenish the water consumed inside the workbench 1.
[0024] In this wood biomass pellet dust removal equipment, the fan 10 draws air from inside the workbench 1 through the air collection pipe 12 and the branch pipe 13, and discharges it to the outside through the exhaust pipe 11, making the inside of the workbench 1 a negative pressure state. Through the effect of air pressure difference, suction is generated inside the workbench 1 to suck up the dust on the wood biomass pellets. The dust enters the inside of the workbench 1 through the holes on the mesh plate 3. The motor 9 can drive the water wheel 6 to rotate at high speed inside the workbench 1, so that the water wheel 6 continuously hits the liquid surface to generate water splashes. After the dust-laden gas passes through the water splashes, it can capture the dust and guide it to settle at the bottom of the workbench 1 through the guide plate 7, so as to remove the dust on the wood biomass pellets.
