One side of the spray tower body near the lower part is communicated with an air inlet pipe, the top of the spray tower body is communicated with an air outlet pipe, and a water filtering plate is installed inside the spray tower body near the air outlet pipe. Among them, a packing is arranged in the middle of the inner side of the spray tower body; in this utility model, a rotating pipe drives a spray head to rotate, so that the spray head can rotate when spraying water, and the sprayed water can be evenly sprayed, enabling the gas phase and the liquid phase to fully contact.

[0004] In the above technology, although the spray head can be rotated to make the sprayed solution more uniform, treating the waste gas through the mixing reaction of the solution with the waste gas will increase the acidity of the waste gas, resulting in the treated waste gas corroding subsequent pipelines, etc. For this reason, a waste gas treatment equipment containing citric acid is proposed to solve the above problems. Summary of the Utility Model

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 - Figure 2 As shown in the figure, an embodiment provided by the present utility model: An exhaust gas treatment device containing citric acid includes a spray tower 1. A spray head is arranged inside the spray tower 1 to spray a citric acid solution for neutralization reaction of the exhaust gas. The right part of the spray tower 1 is fixedly connected with a water tank 2. A water pump is fixed inside the water tank 2 to circulate the aqueous solution. The upper part of the water tank 2 is fixedly connected with a water inlet pipe 3. The water inlet pipe 3 can transport the solution inside the water tank 2 to the inside of the spray head for spraying. The left part of the water inlet pipe 3 is fixedly connected to the side part of the spray tower 1. The spray tower 1 keeps the water inlet pipe 3 relatively fixed. The upper part of the spray tower 1 is fixedly connected with an air outlet pipe 7. The air outlet pipe 7 can discharge the treated exhaust gas. The upper part of the spray tower 1 is fixedly connected with a fixed groove 6. The fixed groove 6 restricts the filter plate 5 to only slide horizontally within a fixed distance relatively.

[0032] Refer to Figure 1 - Figure 3, at the upper parts of both ends of the fixed groove 6, there are positioning blocks 8 fixedly connected. The positioning blocks 8 are U-shaped, restricting the clamping block 10 to slide vertically within a fixed distance. The lower part of the positioning block 8 is elastically connected to the clamping block 10 through a first spring 13. The lower end side of the clamping block 10 is inclined, and it can slide upward under the extrusion of the sliding rod 11. This facilitates the sliding of the filter plate 5 to both ends of the fixed groove 6. One end of the first spring 13 is fixedly connected to the inside of the clamping block 10, and the other end of the first spring 13 is fixedly connected to the middle inner wall of the positioning block 8. When the first spring 13 is squeezed by the positioning block 8, the clamping block 10 can slide into the middle inside of the sliding rod 11 to keep the filter plate 5 fixed relative to the fixed groove 6. The outer part of the lower end of the clamping block 10 is slidably connected to the middle inside of the sliding rod 11. The two groups of front and rear clamping blocks 10 are fixedly connected by a connecting rod 9. The connecting rod 9 can drive the clamping blocks 10 at both ends to slide upward simultaneously, so that the filter plate 5 can slide horizontally, quickly completing the replacement of the activated carbon. A sliding rod 11 is slidably connected inside the fixed groove 6. The sliding rod 11 can drive the filter plate 5 to slide horizontally. The side end of the sliding rod 11 is fixedly connected to the filter plate 5. Activated carbon can be placed inside the filter plate 5 to adsorb acidic substances such as citric acid compounded in the waste gas, so that the waste gas will not corrode the air outlet pipe 7. The outside of the filter plate 5 is in contact with the upper inner part of the spray tower 1. A gear component is slidably connected inside the side end of the filter plate 5.

[0033] Refer to Figure 1 , Figure 2 and Figure 4 , the gear component includes a stopper 4. The stopper 4 can seal the side parts at both ends of the filter plate 5 to keep the activated carbon fixed inside the filter plate 5. The outside of the stopper 4 is slidably connected to the inside of the side end of the filter plate 5. Sliding the stopper 4 upward can quickly clean out the activated carbon. A slider 12 is fixedly connected to the side end of the stopper 4. The slider 12 can restrict the stopper 4 to slide vertically relative to the filter plate 5. The outside of the slider 12 is slidably connected to the inside of both ends of the filter plate 5. A magnet 14 is fixedly connected to the inside of the lower end of the slider 12. The adsorption of the magnet 14 can keep the stopper 4 relatively fixed and stable. The outside of the magnet 14 is in contact with the inside of both ends of the filter plate 5.

[0034] Working principle: By placing activated carbon inside the external filter plate 5, then sliding the connecting rod 9 upwards. The upward sliding of the connecting rod 9 can drive the clamping blocks 10 at both ends to slide upwards. The upward sliding of the clamping blocks 10 compresses the first spring 13. When the clamping blocks 10 slide out of the inside of the sliding rod 11, then slide the filter plate 5 horizontally, so that the filter plate 5 inside the spray tower 1 slides out. Release the connecting rod 9, and the clamping blocks 10 slide back to their original positions under the extrusion of the first spring 13. Another filter plate 5 with activated carbon placed on it slides into the inside of the spray tower 1. At this time, the sliding-out filter plate 5 squeezes the side inclined surface of the clamping blocks 10 to make them slide upwards and compress the first spring 13. Then, when the sliding-out filter plate 5 slides to the point where it is no longer slidable by the fixing groove 6, the clamping blocks 10 slide downwards to the middle inside of the sliding rod 11 under the extrusion of the first spring 13 to fix the filter plate 5. Then, the stopper 4 can be slid upwards. The stopper 4 drives the sliders 12 and magnets 14 at both ends to slide out of the side inside of the filter plate 5, clean out the activated carbon, and then slide the stopper 4 and the sliders 12 and magnets 14 at both ends back to their original positions to maintain fixation.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
