[0029] 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.
[0030] Reference Figure 1 , Figure 2 and Figure 4 The utility model provides an embodiment: a glass fiber reinforced plastic desulfurization tower for industrial waste gas treatment, comprising a reaction barrel 1, an air inlet pipe 2 is fixedly connected to the outside of the reaction barrel 1, an air outlet pipe 3 is fixedly connected to the outside of the reaction barrel 1, a limiting block 5 is fixedly connected to the top of the reaction barrel 1, a motor 24 is fixedly connected to the outside of the limiting block 5, a fixed block 4 is fixedly connected to the outside of the limiting block 5, a turntable 7 is rotatably connected to the outside of the limiting block 5, a connecting piece 8 is fixedly connected to the eccentric part of the outside of the turntable 7, and a ring piece 1 is slidably connected to the outside of the turntable 7 0, the outside of the ring member 10 is fixedly connected with two moving rods 6, the top of the reaction barrel 1 is fixedly connected with a liquid box 9, the outside of the liquid box 9 is fixedly connected with a support tube 13, the inner wall of the support tube 13 is slidably connected with a piston 23, the outside of the support tube 13 is fixedly connected with an infusion tube 11, the outside of the infusion tube 11 is fixedly connected with a control valve 12, the outside of the support tube 13 is fixedly connected with an infusion tube 2 15, the outside of the infusion tube 2 15 is fixedly connected with a control valve 2 14, and an adjustable component is arranged inside the reaction barrel 1.
[0031] Specifically, the sulfur-containing gas enters the interior of the reaction barrel 1 through the air inlet pipe 2, and the motor 24 is started. The output end of the motor 24 drives the turntable 7 to rotate, and then drives the connecting member 8 to move synchronously. The connecting member 8 drives the annular member 10 to rotate. At this time, under the action of the annular member 10, the movable rod 6 pulls the piston 23 outward. At this time, the control valve 12 is opened, and the control valve 2 14 is closed. The alkaline liquid in the liquid tank 9 enters the support cylinder 13 through the infusion tube 11. At the same time, the annular member 10 drives the movable rod 6 to push the piston 23 inward. At this time, the control valve 12 is closed, and the control valve 2 14 is opened. Under the action of the piston 23, the alkaline liquid is transported through the infusion tube 2 15, and then sprayed through the nozzle, thereby realizing quantitative spraying of the alkaline liquid. Quantitative spraying ensures that the amount of alkaline liquid used is accurately controlled to avoid excessive use, which helps to reduce liquid waste and thus reduce operating costs.
[0032] Reference Figure 3 The adjustable component includes a mounting column 21, which is fixedly connected to the inner wall of the reaction barrel 1. A connecting groove 22 is opened on the outside of the mounting column 21. The inner wall of the connecting groove 22 is rotatably connected with a threaded rod 18. The outer thread of the threaded rod 18 is threadedly connected with a slider 20. The outer side of the slider 20 is fixedly connected with an internal tube 19. The outer side of the internal tube 19 is fixedly connected with a conduit 17. The outer side of the conduit 17 is fixedly connected with an air pump 27. The outer side of the reaction barrel 1 is fixedly connected with a water tank 16. The top of the reaction barrel 1 is fixedly connected with a motor 25.
[0033] Specifically, when desulfurization is completed and the reaction barrel 1 needs to be cleaned, the water in the water tank 16 is heated by the heating rod to generate steam, and the motor 25 is started. The output end of the motor 25 drives the threaded rod 18 to rotate, and then drives the slider 20 to slide along the inner wall of the connecting groove 22, and then drives the internal pipe 19 to move synchronously. At this time, the air pump 27 is started, so that the steam inside the water tank 16 enters the internal pipe 19 through the conduit 17, and then sprays out through the injection pipe. Under the action of the slider 20, the injection pipe is driven to move up and down. The injection pipe that moves up and down covers a wider surface area, and the cleaning process can be completed more quickly than the fixed nozzle. This helps to reduce downtime and improve equipment availability and production efficiency.
[0034] Reference Figure 1 and Figure 3 One end of one moving rod 6 away from the ring member 10 is slidably connected to the outer side of the fixed block 4, and the other end of the moving rod 6 away from the ring member 10 is fixedly connected to the outer side of the piston 23.
[0035] Specifically, the annular member 10 is limited by the fixing block 4 to prevent the annular member 10 from rotating along with the connecting member 8 , and the annular member 10 drives the moving rod 6 to move, so that the moving rod 6 pulls the piston 23 outward.
[0036] Reference Figure 1 and Figure 3 The outside of the connecting member 8 is slidably connected to the inner wall of the annular member 10 .
[0037] Specifically, the outer portion of the connecting member 8 fits with the inner wall of the annular member 10 , and when the connecting member 8 rotates, the annular member 10 is driven to rotate.
[0038] Reference Figure 1 and Figure 3 One end of the infusion tube 11 away from the support tube 13 is connected to the outside of the liquid box 9, and one end of the infusion tube 2 15 away from the support tube 13 is fixedly connected to the inner top wall of the reaction barrel 1, and one end of the infusion tube 2 15 is fixedly connected to the nozzle.
[0039] Specifically, the alkaline liquid in the liquid box 9 enters the interior of the support tube 13 through the infusion tube 1 11 , and one end of the infusion tube 2 15 is fixed to the inner top wall of the reaction barrel 1 to increase the stability of the nozzle.
[0040] Reference Figure 1 and Figure 2 Four support columns are fixedly connected to the outside of the reaction barrel 1, an anti-skid layer is fixedly connected to the bottom of the support columns, and a liquid guide hopper 26 is fixedly connected to the bottom of the reaction barrel 1.
[0041] Specifically, the reaction barrel 1 is supported by four support columns and kept away from the ground. The anti-skid layer increases the friction of the support columns and ensures the stability of the reaction barrel 1. The alkaline liquid after the desulfurization reaction flows out through the liquid guide hopper 26, which is convenient for the staff to collect.
[0042] Reference Figure 3 The longitudinal section of the slider 20 is square, and the outer portion of the slider 20 is slidably connected to the inner wall of the connecting groove 22.
[0043] Specifically, when the threaded rod 18 rotates, the slider 20 slides along the inner wall of the connecting groove 22, making the slider 20 more stable and further improving the stability of the inner tube 19 when it moves up and down.
[0044] Reference Figure 2 and Figure 3 A plurality of spray pipes are fixedly connected to the outside of the inner tube 19 , and one end of the conduit 17 away from the inner tube 19 is connected to the water tank 16 , and a heating rod is fixedly connected to the inside of the water tank 16 .
[0045] Specifically, the water in the water tank 16 is heated by the heating rod to generate steam, and the steam is transported to the internal pipe 19 through the conduit 17 , and then the steam is sprayed out through a plurality of spray pipes to clean the inner wall of the reaction barrel 1 .
[0046] Working principle: When this device is used, the sulfur-containing gas enters the interior of the reaction barrel 1 through the air inlet pipe 2, and the motor 24 is started. The output end of the motor 24 drives the turntable 7 to rotate, and then drives the annular member 10 to rotate through the connecting member 8. At this time, the annular member 10 drives the moving rod 6 to move to one side, and pulls the piston 23 outward through the moving rod 6. At this time, the control valve 12 is opened, and the control valve 2 is closed. The alkaline liquid in the liquid tank 9 enters the support cylinder 13 through the infusion pipe 11, and then the annular member 10 drives the moving rod 6 to move to the other side, and the moving rod 6 pushes the piston 23 inward. At this time, the control valve 12 is closed, and the control valve 2 is opened. The alkaline liquid in the support cylinder 13 is transported through the infusion pipe 2 15, and then sprayed through the nozzle, realizing quantitative spraying of the alkaline liquid. Through quantitative spraying, the pH value in the desulfurization tower can be kept within an appropriate range. The appropriate pH value helps to ensure the effective progress of the desulfurization reaction, while avoiding corrosion or scaling problems caused by excessive alkaline liquid.
[0047] In addition, when desulfurization is completed and the reaction barrel 1 needs to be cleaned, the water in the water tank 16 is heated by the heating rod, and the motor 25 is started. The output end of the motor 25 drives the threaded rod 18 to rotate, and then drives the slider 20 to slide. At this time, by starting the air pump 27, the steam inside the water tank 16 enters the internal tube 19 through the conduit 17, and then is ejected through the injection pipe. Under the action of the slider 20, the internal tube 19 is driven to move up and down. The injection pipe that moves up and down can ensure that the steam is evenly distributed on the inner wall of the desulfurization tower, thereby thoroughly cleaning the entire surface, which helps to remove scale, residues and corrosion products and keep the inner wall of the desulfurization tower clean.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
