Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Depend on Figures 1 to 3 The utility model provides a corrosion-resistant spray washing tower, comprising a glass fiber reinforced plastic tower body 1, an air inlet pipe 2 is inserted into the bottom end of one side of the glass fiber reinforced plastic tower body 1, an exhaust pipe 3 is fixedly provided at the top of the glass fiber reinforced plastic tower body 1, an aluminum alloy sprayer 4 is inserted into the top of the interior of the glass fiber reinforced plastic tower body 1, an aluminum alloy dispersed exhaust mechanism 5 connected to the air inlet pipe 2 is provided at the bottom end of the interior of the glass fiber reinforced plastic tower body 1, an aluminum alloy honeycomb reactor 1 6 and an aluminum alloy honeycomb reactor 2 7 are fixedly provided at the middle position of the interior of the glass fiber reinforced plastic tower body 1, the aluminum alloy dispersed exhaust mechanism 5 is composed of a hollow disc 8, a plurality of air nozzles 9 and a dispersed mesh plate 10, the hollow disc 8 is rotatably connected to the air inlet pipe 2 through a ceramic bearing 11, the air nozzle 9 is fixedly connected to the side of the bottom end of the hollow disc 8, the air nozzle 9 is an inclined structure, and the dispersed mesh plate 10 is sleeved on the air inlet pipe 2 and fixedly connected thereto;

[0024] By setting the components of the spray scrubber to be made of glass fiber reinforced plastic and aluminum alloy, the corrosion resistance can be improved. The exhaust gas enters the interior of the hollow disc 8 through the air inlet pipe 2 and is then ejected through the air nozzle 9. Since the air nozzle 9 is an inclined structure, the reaction force of the gas is used to drive the hollow disc 8 to rotate. The ejected gas can stir the reaction liquid at the bottom end of the glass fiber reinforced plastic tower body 1 and pre-treat the exhaust gas at the same time. The pre-reacted exhaust gas is dispersed and discharged through the dispersion mesh plate 10.

[0025] Depend on Figure 2 and Figure 4It is shown that the aluminum alloy honeycomb reactor 1 6 and the aluminum alloy honeycomb reactor 2 7 are both composed of a honeycomb top plate 12, a breathable membrane 13 and a honeycomb bottom plate 14. The breathable membrane 13 is located at the top of the honeycomb bottom plate 14, the honeycomb top plate 12 is located at the top of the breathable membrane 13, and an inner groove 15 is opened in the middle of the bottom end of the honeycomb top plate 12;

This process allows the exhaust gas to fully contact with the reaction liquid, thereby improving the adequacy of the reaction.

[0027] Depend on Figure 1 、 Figure 3 and Figure 5 It is given that an overflow pipe 16 is inserted into the bottom end of one side of the FRP tower body 1.

A notch 20 matching the cover plate 17 is opened on the side of the dispersion mesh plate 10.

[0028] The overflow pipe 16 is used to overflow the reaction liquid at the bottom, thereby realizing continuous replacement of the reaction liquid. The cover plate 17 enables the reaction liquid at the bottom to be discharged first, thereby preventing the unreacted reaction liquid from being discharged.

[0029] Depend on Figure 1 It is shown that a reinforcement ring 21 is fixedly provided on the arc-shaped outer surface of the FRP tower body 1, and a plurality of inspection ports 22 are provided on the side of the FRP tower body 1;

[0030] The FRP tower body 1 can be reinforced by the reinforcement ring 21 , and the inspection port 22 allows staff to conveniently inspect and maintain the interior of the FRP tower body 1 .

[0031] During operation, by arranging a fiberglass tower body, an aluminum alloy sprayer, an aluminum alloy dispersed exhaust mechanism, an aluminum alloy honeycomb reactor 1 and an aluminum alloy honeycomb reactor 2, the overall corrosion resistance can be improved, thereby increasing the service life of the spray washing tower. By arranging a reinforcement ring, the spray washing tower can be reinforced to improve the overall strength. By arranging an aluminum alloy dispersed exhaust mechanism composed of a hollow disc, a plurality of air nozzles and a dispersed mesh plate, the exhaust gas and the reaction liquid can be pre-reacted to achieve pretreatment of the exhaust gas. At the same time, the reaction liquid can be stirred and the exhaust gas can be dispersed. By arranging an aluminum alloy honeycomb reactor 1 and an aluminum alloy honeycomb reactor 2 composed of a honeycomb top plate, a breathable membrane and a honeycomb bottom plate, the contact between the exhaust gas and the reaction liquid can be further improved, thereby improving the exhaust gas treatment effect.
