[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Reference Figure 1 and Figure 2The dust removal system shown in the figure comprises a dust removal tower 10, on which an air inlet pipe 11, an air outlet pipe 12, a water outlet 13, a mixed flow fan blade 14 and a plurality of spray heads 15 are arranged, the air outlet pipe 12 is connected to an external water vapor separation device, the spray head 15 is connected to an external water pump, the water outlet 13 is arranged at the bottom of the dust removal tower 10 and connected to a water storage tank 16, the air inlet pipe 11 is arranged at the lower end of the dust removal tower 10, the air outlet pipe 12 is arranged at the upper end of the dust removal tower 10, and the mixed flow fan blade 14 is rotated The shaft 17 is connected to the drive motor 18, and the air flow containing dust enters the dust removal tower 10 from the air inlet pipe 11. The drive motor 18 drives the mixed flow fan blades 14 to rotate. At the same time, the water pump starts and drives the spray head 15 to spray water mist into the dust removal tower 10. The mixed flow fan blades 14 rotate to disturb the air flow in the dust removal tower 10, so that the dust can be fully mixed with the sprayed water mist and condensed into water droplets. The water droplets flow from the inner wall of the dust removal tower 10 through the water outlet 13 to the water storage tank 16, and the water storage tank 16 can be connected to an external water filter device.

[0018] In some possible embodiments, the mixed flow blades 14 are arranged above the air inlet pipe 11 to avoid disturbing the air flow in the dust removal tower 10 when the mixed flow blades 14 rotate and hindering the air flow containing dust from being transported into the dust removal tower 10 through the air inlet pipe 11, so as to ensure the exhaust and dust removal efficiency in the dust removal tower 10.

[0019] In some possible embodiments, the mixed flow blade 14 includes a plurality of blades 19, and the rotation directions of two adjacent blades 19 are opposite, the purpose of which is to further enhance the disturbance efficiency of the mixed flow blade 14, so that the dust is disorderly disturbed with the airflow in the dust removal tower 10, ensuring that the dust can be fully mixed with the spray water mist; the design of the mixed flow blade 14 in this embodiment can ensure that the airflow does not flow from bottom to top to improve efficiency at the expense of the mixing rate of dust and spray water mist; and in other embodiments, after the mixed flow blade 14 rotates, the airflow direction of the dust removal tower 10 is downward to slow down the rate at which the airflow rises and flows out of the outlet pipe 12, thereby increasing the time for the dust to mix with the spray water mist. This method reduces efficiency and thus improves the dust removal effect.

[0020] In some possible embodiments, there are two mixed flow blades 14, and the rotation directions of the two mixed flow blades 14 are opposite. The airflow generated by the lower mixed flow blade 14 is upward, and the airflow generated by the upper mixed flow blade 14 is downward. The two airflows collide between the two mixed flow blades 14 to generate a mixed flow air field. In this way, the dust can be more fully mixed with the spray water mist to improve the dust removal effect.

[0021] In some possible embodiments, a mesh plate 20 is further provided in the dust removal tower 10, and there are a plurality of spray heads 15 that are evenly distributed vertically downward at the bottom of the mesh plate 20. The spray heads 15 spray water mist downward so that the water mist can be fully mixed with the dust and condensed into water droplets. Most of the water droplets are disturbed by the mixed flow blades 14 to perform centrifugal motion and hit the inner wall of the dust removal tower 10, and the water droplets flow along the inner wall through the water outlet 13 to the water storage tank 16.

[0022] In some possible embodiments, one end of the air intake pipe 11 protrudes inward from the inner wall of the dust removal tower 10. The purpose is to prevent condensed water droplets from flowing into the air intake pipe 11 along the inner wall of the dust removal tower 10 and mixing with dust in the air intake pipe 11, and accumulating at the end of the air intake pipe 11, thereby reducing the air intake efficiency.

[0023] In some possible embodiments, there are several spray heads 15 distributed around the dust removal tower 10. The purpose is to form centrifugal force on the airflow when the mixed flow blades 14 rotate, so that more airflow rotates along the circumferential direction of the inner wall of the dust removal tower 10. Setting the spray heads 15 around the dust removal tower 10 can enhance the effect of mixing the spray water mist and dust.

[0024] In some possible embodiments, a mounting base 21 is further included, and the dust removal tower 10 is arranged in the mounting base 21. A water storage tank 16 is arranged at the lower end of the mounting base 21, and one side of the mounting base 21 is also opened. The dust is mixed with the spray water mist and flows into the water storage tank 16 through the water outlet 13, and forms water foam on the upper surface of the water storage tank 16. The staff can manually clean the water foam gathered on the surface of the water tank to reduce the workload of subsequent water filtration. Furthermore, the water outlet 13 is immersed in the water surface of the water storage tank 16. The purpose is to prevent dust from being sent out from the water outlet 13 along with the disturbed airflow in the dust removal tower 10 and polluting the surrounding environment.

[0025] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
