[0020] 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.

[0021] See also Figure 1-4 The utility model provides a technical solution: a VOC waste gas treatment spray washing tower, including a first tower body 1, the interior of the first tower body 1 is rotatably connected with a rotating plate 5, the lower surface of the rotating plate 5 is fixedly connected with a plurality of capillaries 52, the top of the first tower body 1 is rotatably connected with an air inlet pipe joint 11, the bottom end of the air inlet pipe joint 11 extends into the rotating plate 5 and is connected with the plurality of capillaries 52, a water tank 6 is fixedly connected inside the first tower body 1 and below the capillary 52, the bottom end of the capillary 52 extends into the water tank 6, and the lower surface of the water tank 6 is fixedly connected with a plurality of atomizing nozzles 62.

[0022] Specifically, the gas enters the first tower body 1 through the air inlet pipe joint 11. When the gas enters, it is diverted by the capillary 52 and enters the treatment liquid in the water tank 6, thereby increasing the contact area with the treatment liquid and thus increasing the reaction efficiency. Subsequently, the atomizing nozzle 62 sprays the treatment liquid in the water tank 6 to perform a secondary reaction on the gas in the first tower body 1. Through the above operation, the treatment liquid can be reused to avoid waste of treatment liquid and incomplete gas reaction.

[0023] The second tower body 2 is arranged on the side of the first tower body 1. The bottom ends of the first tower body 1 and the second tower body 2 are fixedly connected through a bottom plate 3. The peripheral sides of the first tower body 1 and the second tower body 2 are fixedly connected with a connecting pipe 12 and a water pipe 13 respectively.

[0024] Specifically, the gas in the first tower body 1 and the treated liquid recollected after atomization are guided by the connecting pipe 12 and the water pipe 13 and enter the second tower body 2 .

[0025] The circumferential side of the connecting pipe 12 is fixedly connected with a gas detector 121 and a stop valve 122 . The height of the connecting pipe 12 is greater than the water pipe 13 . The end of the connecting pipe 12 extends into the second tower body 2 and bends downward.

[0026] Specifically, the gas detector 121 and the stop valve 122 are both existing technologies. The gas detector 121 detects the flowing gas to determine whether the gas is cleanly treated. The stop valve 122 controls the flow rate of the gas when the gas treatment is insufficient. The end of the connecting pipe 12 extends into the second tower body 2 and bends downward and extends into the treatment liquid of the second tower body 2. The treatment liquid in the second tower body 2 reacts again to the gas discharged from the connecting pipe 12.

[0027] The water tank 6 is fixedly connected to the first tower body 1 through a connecting rod 61. A water pump is fixedly installed in the water tank 6. The output end of the water pump is fixedly connected to the atomizing nozzle 62. A driving device 4 for driving the rotating plate 5 to rotate is fixedly installed on the top of the first tower body 1.

[0028] Specifically, the water pump provides power for the atomization of the atomizing nozzle 62, and the driving device 4 drives the rotating plate 5 to rotate, thereby driving the capillary 52 to rotate, stirring the processing liquid, so as to further increase the contact between the gas and the reaction liquid.

[0029] A T-shaped ring block 51 is fixedly connected to the upper surface of the rotating plate 5, a T-shaped ring groove 14 matching the T-shaped ring block 51 is opened on the inner wall of the top of the first tower body 1, a ring tooth 511 is fixedly connected to the circumferential side of the T-shaped ring block 51, and the driving device 4 includes a motor 42, the output end of the motor 42 extends into the top of the first tower body 1 and is fixedly connected to a gear 41, and the gear 41 is meshed with the ring tooth 511.

[0030] Specifically, the motor 42 is of the prior art, and drives the gear 41 to rotate. The gear 41 rotates, and under the action of the ring gear 511, drives the T-shaped ring block 51 to rotate, thereby realizing the rotation of the rotating plate 5.

[0031] A partition 22 is fixedly connected inside the second tower body 2 and above the connecting pipe 12. A box 23 is fixedly installed on the upper surface of the partition 22. A through hole 221 connected to the box 23 is opened on the lower surface of the partition 22. The box 23 is filled with an activated carbon layer 231.

[0032] Specifically, the partition 22 divides the second tower body 2 into two independent cavities, so that the gas can only enter the box body 23 through the through hole 221. The activated carbon layer 231 in the box body 23 filters the gas to further improve the cleanliness of the gas when it is discharged. The top of the second tower body 2 is fixedly connected to the gas outlet pipe 21.

[0033] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0034] During operation, the gas enters the first tower body 1 through the air inlet pipe joint 11, and the gas entering the first tower body 1 flows into the treatment liquid in the water tank 6 through the capillary 52. ​​The treatment liquid preliminarily purifies the gas, and then the atomizing nozzle 62 atomizes and sprays the treatment liquid in the water tank 6 to purify the gas for the second time. The gas after the secondary purification enters the treatment liquid in the second tower body 2 through the connecting pipe 12. The treatment liquid in the second tower body 2 finally treats the gas, and then the gas is filtered through the activated carbon layer 231 and discharged from the second tower body 2.
