The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0027] See also Figure 1-6The utility model discloses a biomass production negative pressure dust removal and recovery system, comprising a bag-type dust collector 1, a collecting box 2 is arranged on the outside of the bag-type dust collector 1, a rolling component for humidification is arranged on the inside of the collecting box 2, a movable plate 3 for cooperating with the rolling component to close the discharge port is arranged at the discharge port of the bag-type dust collector 1, an elastic member is arranged between the movable plate 3 and the collecting box 2, a driving component for driving the rolling component to rotate at a uniform speed is arranged on the outside of the collecting box 2, a belt 7 is connected between the driving component and the rolling component, and a filter container for collecting dust and waste liquid is installed on the inside of the collecting box 2.

[0028] See also Figure 3 In order to humidify the dust processed by the bag-type dust collector 1, the collecting box 2 is composed of a box neck 21 and a box body 22. The box neck 21 is arranged on the outside of the discharge port of the bag-type dust collector 1. The centers of the two ends of the box neck 21 are provided with bearings 211 penetrating the box neck 21. The rolling assembly is composed of a roller 5, a swivel joint 501 and a first pulley 502. The roller 5 is elliptical, and the two ends of the roller 5 are installed on the inner sides of the two bearings 211 and extend to the outside of the box neck 21. One end of the roller 5 is provided with an inner cavity for liquid circulation. The surface of the roller 5 is provided with a liquid outlet connected to the inner cavity. The diameter of the liquid outlet is small, and the water flow of the liquid can only keep wetting the surface of the roller 5 and humidify the dust falling on the surface of the roller 5. The swivel joint 501 is installed at one end of the roller 5 with the inner cavity. The swivel joint 501 is connected to the water supply pipe. When the roller 5 rotates, the water supply pipe can still transport water to the inner cavity of the roller 5 through the swivel joint 501, which does not affect the rotation of the roller 5. The first pulley 502 is installed on the end of the drum 5 away from the rotary joint 501. The elastic member is composed of a spring sheet 4. The movable plate 3 is symmetrically distributed with the center of the drum 5 as the origin and is installed at the discharge port of the bag dust collector 1. The movable plate 3 can cooperate with the drum 5 to close the discharge port of the bag dust collector 1 and fit the surface of the drum 5 so that the fallen dust can only contact the surface of the drum 5 to achieve the purpose of humidification. The spring sheet 4 is installed between the movable plate 3 and the inner wall of the box neck 21. Since the drum 5 is elliptical, during the rotation of the drum 5, the drum 5 can squeeze the movable plate 3 through the two ends with longer diameters to provide a channel for the humidified dust to be discharged, and the spring sheet 4 will be compressed between the movable plate 3 and the box neck 21. When the drum 5 rotates to the narrower ends and contacts the movable plate 3, the spring sheet 4 will squeeze the movable plate 3 through the restoring elastic force, so that the movable plate 3 is in close contact with the drum 5 and moves to its original position.

[0029] See also Figure 4, providing power for the rotation of the drum 5. The box body 22 is arranged at the end of the box neck 21 away from the bag-type dust collector 1. A boss 221 and a slot 222 are arranged on the side of the box body 22 close to the first pulley 502. The slot 222 is located at the end of the box body 22 away from the bag-type dust collector 1 and passes through the box body 22. The boss 221 provides a platform for the installation of the drive motor 6, and the slot 222 provides an extension channel for the liquid outlet 801 of the waste box 8, so that the waste liquid separated inside the waste box 8 can be directly discharged to the outside for treatment. The driving assembly consists of a drive motor 6 and a second pulley 601. The drive motor 6 is installed on the side of the boss 221 close to the bag-type dust collector 1, and the second pulley 601 is installed at the output end of the drive motor 6. The belt 7 is connected to the outside of the first pulley 502 and the second pulley 601.

[0030] See also Figure 5 , automatically processes the dust after humidification, the filter container is composed of a waste box 8 and a filter plate 9, the side of the box body 22 away from the boss 221 is open, the waste box 8 is installed on the inner side of the box body 22, and the outer side of the waste box 8 is provided with a liquid outlet 801 extending along the groove 222 to the outside of the box body 22, and the filter plate 9 is arranged at the center of the inner side of the waste box 8. The dust after humidification and the water droplets sprayed by the drum 5 will all be collected in the waste box 8, the humidified dust will be filtered by the filter plate 9, and the waste liquid will be separately diverted by the liquid outlet 801 for collection and treatment.

[0031] When the dust needs to be humidified, first start the bag filter 1 and the drive motor 6, and connect the water supply pipe to the rotary joint 501. The rotary joint 501 will drain the water into the inner cavity of the drum 5, and slowly seep out through the liquid outlet on the surface. The bag filter 1 will discharge the treated dust toward the discharge port of the hopper. The discharged dust will fall on the surface of the drum 5 and mix with the water to complete the humidification. The drive motor 6 will force the drum 5 and the outer first pulley 502 to rotate at a constant speed in the bearing 211 through the second pulley 601 and the belt 7 at the output end. The drum 5 rotates during the process. During the process, the movable plates 3 and spring sheets 4 on both sides will be continuously squeezed through the two ends with a longer spacing. The dust and waste liquid humidified on the surface of the drum 5 will be discharged from the box neck 21 during the process of the movable plate 3 being stretched open, and will fall into the waste box 8. When the two ends of the drum 5 with a smaller spacing come into contact with the movable plate 3, the spring sheet 4 will push the movable plate 3 to move to its original position while maintaining contact with the drum 5 through the restoring elastic force. The dust and waste liquid that fall into the waste box 8 will be filtered by the filter plate 9. The dust will remain on the surface of the filter plate 9, while the waste liquid will pass through the filter plate 9 and be discharged along the liquid outlet 801 for treatment.
