[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a spraying device for a desulfurization tower, comprising a tower body 1, an exhaust pipe 3 fixedly connected to the top of the tower body 1, and an air inlet pipe 2 fixedly connected to the side wall of the bottom of the tower body 1. By providing the air inlet pipe 2, the exhaust gas enters the interior of the tower body 1 from the air inlet pipe 2 and is sprayed and degraded by annular nozzles 5. The degraded gas is discharged outward from the exhaust pipe 3. An annular nozzle 5 is fixedly connected to the top of the inner side wall of the tower body 1, and an external pipe 4 is fixedly connected to the outer side wall of the annular nozzle 5. An adjustable flange assembly 8 is provided at the end of the external pipe 4 away from the annular nozzle 5. Multiple sets of spray nozzles 6 are provided at the bottom of the annular nozzle 5. Spray water from an external water supply device enters the interior of the annular nozzle 5 from the external pipe 4 and is sprayed outward from the multiple sets of spray nozzles 6, thereby degrading the exhaust gas entering the interior of the tower body 1. A shielding assembly 7 is provided on the inner arc surface of the annular nozzle 5.

[0035] Reference Figure 3 - Figure 5 The adjustable flange assembly 8 includes a flange 81, which is fixedly connected to the end of the outer pipe 4 away from the annular nozzle 5. The outer pipe 4 passes through and is fixedly connected to the inner side wall of the tower body 1. A gear ring 82 is rotatably connected to the inner side wall of the flange 81. The inner diameter of the gear ring 82 matches the inner side of the flange 81, and the spacing of the teeth at its bottom end matches the gear 88. A hinge rod 83 is hinged to the upper surface of the gear ring 82, and a mounting base 84 is hinged to the end of the hinge rod 83 away from the gear ring 82. The surface of the flange 81 is provided with a guide groove. The mounting seat 84 is slidably connected to the inner wall of the guide groove of the flange 81. When the gear ring 82 rotates, it will synchronously drive multiple sets of hinge rods 83 to pull the corresponding mounting seat 84 to move inside the flange 81, thereby adjusting the position of the internal thread groove of the mounting seat 84 to adjust according to the flange hole position connected to the outer pipe 4. The outer wall of the gear ring 82 is meshed with a gear 88. When the gear 88 rotates, it will mesh with the gear ring 82, thereby allowing the gear ring 82 to rotate in place.

[0036] Reference Figure 4 - Figure 5A telescopic rod 87 is fixedly connected to the top of gear 88, and a screw 86 is slidably connected to the top of telescopic rod 87. When screw 86 rotates, it drives telescopic rod 87 to rotate synchronously. Simultaneously, when screw 86 rotates, it drives both telescopic rod 87 and screw 86 to rotate synchronously. Half of the length of telescopic rod 87 is located on the inner wall of screw 86. An external threaded groove is formed on the outer wall of screw 86, and a fixed seat 85 is threadedly connected to the outer surface of screw 86. When screw 86 moves up and down within the fixed seat 85, it drives telescopic rod 87 to rotate synchronously with it, simultaneously extending and retracting. One end of rod 87 is fixed to gear 88, so that when screw 86 rotates, telescopic rod 87 will extend on the inner wall of screw 86, thereby preventing screw 86 from moving up and down synchronously with telescopic rod 87 when the screw moves up and down. Gear 88 is rotatably connected to the bottom end of inner wall of flange 81. Fixed seat 85 is fixedly connected to upper surface of flange 81. The surface of mounting seat 84 has an internal thread groove. The inner wall of mounting seat 84 is threaded through and connected to mounting screw 89. The surface of flange 81 has a through guide groove. Mounting screw 89 is through and slidably connected to the inner wall of guide groove of flange 81.

[0037] Reference Figure 2 and Figure 6 The shielding assembly 7 includes two sets of fixing frames 71. The inner side wall of the left fixing frame 71 is elastically connected to a baffle 73 via a spiral spring 72. One end of the spiral spring 72 is fixedly connected to the inner side wall of the fixing frame 71, and the other end of the spiral spring 72 is fixedly connected to the outer wall of the top of the baffle 73. The function of the spiral spring 72 is to prevent the baffle 73 from unfolding when it is sprayed by the water from the spray head 6, and to automatically reset the baffle 73 when the water pressure impact of the spray water is removed. The baffle 73 is rotatably connected to the inner side wall of the fixing frame 71. By setting the rotatable baffle 73, impurities in the exhaust gas inside the tower body 1 can be shielded, thereby preventing them from being adsorbed at the spray head 6 and causing the spray head 6 to be blocked and unable to spray. The fixing frame 71 is fixedly connected to the inner side wall of the annular spray head 5.

[0038] Working principle: When the position of the mounting base 84 needs to be adjusted according to the flange hole positions of the four external pipe connections, the screw 86 is rotated. The screw 86 rotates threadedly on the inner wall of the fixed base 85, driving the telescopic rod 87 to rotate synchronously. Since one end of the telescopic rod 87 is fixed to the gear 88 and half of its length is on the inner wall of the screw 86, the telescopic rod 87 extends on the inner wall of the screw 86 when the screw 86 rotates, preventing the telescopic rod 87 from moving synchronously up and down when the screw 86 moves up and down. The telescopic rod 87 drives the gear 88 to rotate, and the gear 88 meshes with the gear ring 82, causing the gear ring 82 to rotate in place. When the gear ring 82 rotates, it pulls the mounting base 84 to move inside the flange 81 through the hinge rod 83, adjusting the position of the threaded groove inside the mounting base 84 to adapt to the flange hole positions of the four external pipe connections.

[0039] The exhaust gas enters the tower body 1 through the inlet pipe 2. The spray water from the external water supply equipment enters the annular nozzle 5 through the external pipe 4, and then is sprayed outward from multiple sets of spray nozzles 6. The spray water comes into full contact with the exhaust gas entering the tower body 1, degrading the exhaust gas. The treated gas is discharged outward from the exhaust pipe 3, thus achieving the purification of the exhaust gas.

[0040] When the spray head 6 sprays water outward, the impact force of the water causes the baffle 73 to rotate and unfold around the rotation point of the inner side wall of the fixed frame 71. When the water pressure impact of the spray water is canceled, the baffle 73 automatically resets under the action of the spiral spring 72 and returns to the initial position, so as to prevent impurities in the exhaust gas from clogging the spray head 6 when it is not in use.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
