[0030] The following is combined with Figure 1-3 This application is described in further detail.
[0031] The embodiment of the present application discloses a spray tower.
[0032] Reference Figure 1 A spray tower includes a vertically arranged tower body 1, and a alkali spray pipe 11 and an acid spray pipe 12 are installed through the side wall of the tower body 1. The alkali spray pipe 11 is located on the upper side of the acid spray pipe 12. Alkali solution flows in the alkali spray pipe 11, and acid mist flows in the acid spray pipe 12. Valves 13 are installed on the acid spray pipe 12 and the alkali spray pipe 11. The opening and closing of the acid spray pipe 12 or the alkali spray pipe 11 are achieved by controlling the opening and closing of the valve 13. A liquid outlet pipe 14 is connected to the bottom of the tower body 1, and a liquid pump 15 and a liquid pumping valve 16 are installed on the liquid outlet pipe 14. Reactants in contact with the reaction can be discharged from the liquid outlet pipe 14; a disturbance mechanism 2 is also installed in the tower body 1, and the disturbance mechanism 2 further increases the mixing effect of the acid mist and the alkali solution, thereby improving the treatment effect of the acid mist.
[0033] Reference Figure 2 The disturbance mechanism 2 includes a driving component 21 and a disturbance blade 24. The driving component 21 can drive the disturbance blade 24 to rotate in the tower body 1 to achieve full contact between the acid mist and the alkali solution. The driving component 21 includes a motor 211 fixed on the upper side of the tower body 1. A through-hole 17 is opened through the upper side wall of the tower body 1. The axis of the through-hole 17 is located in the same straight line as the axis of the tower body 1. A disturbance shaft 212 is fixed to the output end of the motor 211. The disturbance shaft 212 extends vertically into the tower body 1 through the through-hole 17. The disturbance blade 24 is fixed on the side of the disturbance shaft 212 away from the motor 211. The number of the disturbance blades 24 is two, and the two disturbance blades 24 extend horizontally symmetrically about the disturbance shaft 212.
[0034] When the disturbance blade 24 needs to be replaced after a long period of use, the disturbance blade 24 can be rotated toward the disturbance shaft 212 so that the disturbance blade 24 is parallel to the axis of the disturbance shaft 212, so that the disturbance shaft 212 and the disturbance blade 24 can be removed from the through hole 17.
[0035] Reference Figure 2 and Figure 3 The disturbance shaft 212 includes an inner rod 2121 and an outer tube 2122. The outer tube 2122 is slidably mounted on the outside of the inner rod 2121, and the axes of the two are located in the same straight line. The upper end of the inner rod 2121 extends out of the through-hole 17 and is fixedly connected to the output end of the motor 211. A mounting seat 2123 is fixed on the side wall of the inner rod 2121. The mounting seat 2123 is located in the outer tube 2122. One end of the two disturbance blades 24 is hinged to the mounting seat 2123, and a torsion spring 2124 is fixed between the disturbance blade 24 and the mounting seat 2123. The torsion spring 2124 enables the disturbance blade 24 to extend in a direction away from the disturbance shaft 212, so that the disturbance blade 24 is perpendicular to the disturbance shaft 212.
[0036] The sidewall of the outer tube 2122 is provided with two opposing extension slots 2125, extending along the length of the outer tube 2122. When the extension slots 2125 are aligned with the position of the disturbance blade 24, the disturbance blade 24 is rotated and extended away from the inner rod 2121 under the action of the torsion spring 2124. When the outer tube 2122 is slid vertically away from the mounting seat 2123, the disturbance blade 24 is gradually rotated toward the disturbance shaft 212 until the extension slots 2125 are no longer aligned with the position of the disturbance blade 24. At this time, the disturbance blade 24 is retracted into the outer tube 2122, making it easier to remove.
[0037] Reference Figure 2 The outer tube 2122 is also threaded with a bolt 2126, the axis of the bolt 2126 is perpendicular to the inner rod 2121, and when the bolt 2126 passes through the outer tube 2122 and presses against the inner rod 2121, the outer tube 2122 and the inner rod 2121 are fixed to each other, ensuring the stability of the disturbance blade 24 during rotation.
[0038] The alkali spraying pipe 11 is equipped with a spraying component 22 and a promoting component 23. The spraying component 22 sprays alkali solution downward to mix with the acid mist, and the promoting component 23 further promotes the full contact between the alkali solution and the acid mist to improve the treatment effect.
[0039] The spray assembly 22 includes a spray ring 221 located in the tower body 1. The spray ring 221 is connected to the alkali spray pipe 11. The spray ring 221 is located on the outside of the disturbance shaft 212. A plurality of nozzles 222 are installed on the lower side of the spray ring 221. The nozzles 222 spray alkali solution toward the lower side.
[0040] The promotion component 23 includes a promotion tube 231, which is connected to the alkali spraying pipe 11 and extends downward. A promotion ring 232 is installed on the promotion tube 231. The promotion ring 232 is located below the spray ring 221, and the promotion ring 232 is opposite to the position of the disturbance blade 24. The promotion ring 232 is located on the outside of the disturbance blade 24. The side wall of the promotion ring 232 near the disturbance blade 24 is provided with multiple spray holes 2321. The multiple spray holes 2321 are spaced apart on the promotion ring 232, and the spray holes 2321 can spray alkali solution in the direction close to the disturbance blade 24.
[0041] An acid spray shell 121 is installed through the acid spray pipe 12. The acid spray shell 121 is horizontally arranged below the disturbance blade 24, and the diameter of the acid spray shell 121 is larger than the diameter of the acid spray pipe 12. A plurality of openings 1211 are spaced apart on the upper surface of the acid spray shell 121, and the spraying direction of the openings 1211 is all toward the disturbance blade 24, thereby increasing the spraying area of the acid mist.
[0042] The implementation principle of a spray tower in the embodiment of the present application is:
[0043] When the acid mist needs to be treated, the acid mist enters the tower body 1 through the acid spray pipe 12, and the alkali solution is sprayed downward from the spray component 22. The disturbance blade 24 rotates under the drive of the drive component 21, so that the acid mist and the alkali solution are fully in contact, and the promotion component 23 further improves the contact effect between the two and improves the treatment effect. The reactants in the reaction are finally discharged from the liquid outlet pipe 14.
[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
