[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model. Example

[0015] like Figure 1-Figure 3 As shown, the utility model provides a flue gas dust collector, including a dust box 1, an air inlet pipe 3 is provided on one side of the dust box 1, a drain pipe 4 is provided at the bottom of the dust box 1, an exhaust pipe 5 is provided on one side of the top of the dust box 1, a filter screen 6 is provided at one end of the exhaust pipe 5 facing the inside of the dust box 1, a water inlet pipe 8 is provided on the top of the dust box 1, an atomizing nozzle 9 is provided at the lower end of the water inlet pipe 8, a sliding hole is provided on the top of the dust box 1, a sliding rod 16 is slidably connected in the sliding hole, a cleaning brush 7 is provided at the lower end of the sliding rod 16, and the filter screen 6 can be cleaned by the cleaning brush 7 during the up and down movement of the sliding rod 16. The upper end of the slide bar 16 is fixedly connected to the fixed block 17, and a spring 18 is fixedly connected between the fixed block 17 and the dust removal box 1. The top of the dust removal box 1 is fixedly connected to the vertical plate 10, and one side of the vertical plate 10 is fixedly connected to the electric telescopic rod 11. The telescopic end of the electric telescopic rod 11 is fixedly connected to the cross beam 12, and the lower side of the cross beam 12 is fixedly connected to the hemispherical protrusion 15. The upper surface of the fixed block 17 is an arc surface, and the arc surface is arranged corresponding to the hemispherical protrusion 15.

[0016] The electric telescopic rod 11 drives the crossbeam 12 to move horizontally back and forth. When the hemispherical protrusion 15 contacts the fixed block 17, the hemispherical protrusion 15 can generate downward pressure on the fixed block 17, so that the slide bar 16 moves downward. When the hemispherical protrusion 15 leaves the fixed block 17, the slide bar 16 moves upward under the elastic force of the spring 18. In this way, the slide bar 16 can move back and forth up and down. In this process, the dust attached to the filter net is wiped off by the cleaning brush, which not only prolongs the service life of the filter net, but also enhances the dust removal effect.

[0017] In order to further enhance the dust removal effect, the water inlet pipe 8 is rotatably connected in the center hole at the top of the dust removal box 1, the outer side of the water inlet pipe 8 is sleeved with the toothed ring 14, and the side of the cross beam 12 is fixedly connected with the rack 13, and the rack 13 is meshed with the toothed ring 14. During the horizontal reciprocating movement of the cross beam 12, the rack also reciprocates accordingly, and the water inlet pipe 8 rotates clockwise or counterclockwise under the action of the meshing force between the toothed ring 14 and the rack, and the atomizing nozzle 9 also rotates accordingly, so that the spraying position of the atomizing nozzle 9 can be changed, so that the water mist can fully contact the dust, and the dust removal effect is improved.

[0018] In order to make the horizontal reciprocating movement of the crossbeam smooth, the upper side of the dust box 1 is fixedly connected to the support plate 20, and a guide hole is provided on one side of the support plate 20. The crossbeam 12 passes through the guide hole and can slide back and forth along the guide hole. One end of the crossbeam 12 is fixedly connected to the baffle 19. The support plate 20 provides auxiliary support for the crossbeam, which can ensure that the direction of the crossbeam 12 is accurate during the translation process and that the crossbeam 12 is not easily deformed.
