[0040] Embodiment 1

[0041] Reference Figure 1 to Figure 7 , a stirring and lifting type exhaust gas treatment scrubber, comprising:

[0042] A high support frame 11 and a low support frame 12;

[0043] The separation pipeline 2 is obliquely arranged on the high support frame 11 and the low support frame 12, the lower end of the separation pipeline 2 has a material inlet interface 21, and the upper end of the separation pipeline 2 has a material discharge interface 22;

[0044] A lifting screw 23, which is arranged inside the separation pipe 2;

[0045] A lifting motor 24, which is mounted on the upper end of the separation pipe 2 and is in transmission connection with the lifting screw 23;

[0046] A stirring chamber mechanism 3 is mounted on the low support frame 12, and the stirring chamber mechanism 3 includes a separation chamber body 31, a stirring chamber body 32 disposed in the separation chamber body 31, a stirring motor 33 mounted on the separation chamber body 31, a stirrer assembly 34 driven by the stirring motor 33, an air inlet pipe 35, a liquid inlet pipe 36, an exhaust pipe 37 and a liquid discharge pipe 38;

[0047] A stirring chamber 321 is formed in the stirring chamber body 32, a separation chamber 311 is formed between the stirring chamber body 32 and the separation chamber body 31, and the bottom of the stirring chamber 321 is connected to the bottom of the separation chamber 311; and the stirrer assembly 34 extends into the stirring chamber 321;

[0048] The air inlet pipe 35 and the liquid inlet pipe 36 are both connected to the stirring chamber 321 after passing through the separation chamber 311 , the exhaust pipe 37 is connected to the upper part of the stirring chamber 321 , and the liquid discharge pipe 38 is connected to the bottom of the stirring chamber 321 .

[0049] The above scheme is the basic structural scheme of the utility model, and its working principle is as follows: the waste gas is directly input into the stirring chamber 321 through the air inlet pipe 35, and the filtered aqueous solution is directly input into the stirring chamber 321 through the liquid inlet pipe 36, and the stirring motor 33 is started to stir the filtered aqueous solution and better dissolve and filter the waste gas. A part of the clean gas after filtration enters the separation chamber 311 and is discharged to the outside from the exhaust pipe 37; at the same time, the filtered aqueous solution that absorbs the waste gas enters the separation pipe 2 through the drainage pipe 38, and the lifting motor 24 is started to rotate the lifting screw 23, and then the lifting screw 23 continuously stirs the filtered aqueous solution in the separation pipe 2. During the stirring process, the filtered aqueous solution automatically falls due to gravity, and at the same time, another part of the clean gas separated from the filtered aqueous solution can rise upward and finally be discharged from the discharge interface 22.

[0050] Preferably, a first reducer 241 is further provided between the lifting motor 24 and the lifting screw 23, and a second reducer 331 is further provided between the stirring motor 33 and the stirring assembly 34. By providing the first reducer 241 and the second reducer 331, a deceleration function can be provided to adjust the operating speed of the stirring chamber mechanism 3 and the lifting screw 23.

[0051] It is worth mentioning that, preferably, the exhaust pipe 37 is gradually inclined upward from the inside to the outside to meet the direction of gas movement so that the gas can be discharged smoothly, and the inclined structure can better prevent the filtered water solution from splashing out of the exhaust pipe 37.

[0052] Embodiment 2

[0053] Based on the structure of the first embodiment, this embodiment provides a preferred structural scheme of multiple components, which are as follows:

[0054] 1. Agitator assembly 34: refer to Figure 5 , including a stirring shaft 341, a stirring kettle 342 fixed on the stirring shaft 341, and a stirring blade assembly 343, wherein the stirring shaft 341 is connected to the stirring motor 33 by transmission, the stirring kettle 342 is located in the stirring chamber 321, and the stirring blade assembly 343 is located at the bottom of the separation chamber 311. The stirring kettle 342 and the stirring blade assembly 343 can respectively play a stirring role, so that the waste gas and the filtered water solution can be better contacted and dissolved, thereby improving the waste gas filtering effect.

[0055] It is worth mentioning that the stirring blade assembly 343 preferably includes a plurality of blade units 3431 of different lengths, and the blade units 3431 are evenly spaced along a ring. When the blade units 3431 of different lengths rotate at the same time, different forces can be exerted on the filtered aqueous solution, thereby making the flow of the filtered aqueous solution more disordered, thereby improving the dissolution and filtration effect of the exhaust gas.

[0056] Further set to, refer to Figure 7 The blade unit 3431 is provided with a plurality of spoiler holes 3432 to allow gas to pass through and reduce movement resistance.

[0057] More preferably, it is set to refer to Figure 7 The lower end of the blade unit 3431 is provided with a soft scraper 3433, and the soft scraper 3433 is in contact with the inner wall of the separation chamber 31. The soft scraper 3433 can play a cleaning role, especially the soft scraper 3433 can rotate and abut against the inner wall of the separation chamber 31 to stir the originally deposited solid matter into the filtered water solution to ensure the cleanliness of the inner wall of the separation chamber 31. Finally, the solid matter can be discharged together with the filtered water solution.

[0058] Another preferred setting is to refer to Figure 5, the stirring kettle 342 is a gyro-shaped stirring kettle 342. The gyro-shaped stirring kettle 342 can provide a more uniform stirring effect. Its unique design and rotation mode enable the stirring materials to be evenly dispersed and mixed in three-dimensional space, thereby ensuring a more consistent stirring effect. In addition, during the input of the filtered aqueous solution, it can first contact the gyro-shaped stirring kettle 342, so that the filtered aqueous solution can slide down the gyro-shaped stirring kettle 342, which can effectively prevent the solution from splashing.

[0059] 2. Separation pipeline 2: reference Figure 3-4 The lower end of the separation pipe 2 further extends downward to form a cleaning section 25, and a closed valve 26 is provided on the cleaning section 25. When cleaning is required, the closed valve 26 is opened, so that the filtered aqueous solution in the separation pipe 2 and the stirring chamber mechanism 3 can be discharged downward through the cleaning section 25.

[0060] Furthermore, a plurality of buffer plates 27 are provided in the inner ring of the separation pipe 2, and the buffer plates 27 surround the outer side of the lifting screw 23. When the lifting screw 23 rotates, the filtered water solution is driven to rotate. The arrangement of the buffer plates 27 can prevent the filtered water solution from being directly thrown onto the separation pipe 2, thereby playing an effective buffering and noise reduction function.

[0061] 3. Observation port: Reference Figure 5 The upper end of the separation chamber 31 is provided with an opening 312 connected to the stirring chamber 321, and a cover plate 313 is provided at the opening 312. When the staff needs to observe, the cover plate 313 is opened and the working conditions in the stirring chamber 321 are observed through the opening 312. After the observation is correct, the cover plate 313 is covered again to provide protection.

[0062] It is worth noting that other technical solutions of the present invention belong to the prior art and will not be described in detail.

[0063] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the concept of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
