Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to a collection and purification structure for waste gas spray treatment. Background Technology

[0002] Exhaust gas scrubbing towers are commonly used for industrial waste gas treatment. A common method for waste gas treatment using scrubbing towers is a co-current process, where waste gas is collected in advance by a collection hood, continuously supplied to the purification equipment by a fan, and then transported to the system's scrubbing tower through ventilation ducts. Inside the scrubbing tower, the gas undergoes a scrubbing process, ensuring that odor-causing components in the waste gas fully contact, mix, and react with the scrubbing liquid.

[0003] A search revealed that Publication No. 216223727U discloses a collection and purification structure for SO2 waste gas spray treatment, including a storage tank. A purification tower is connected to the upper surface of the storage tank. A circulation pipe is fixedly connected to one side of the storage tank, and a circulation pump is connected to the surface of the circulation pipe. A dosing pipe is connected to the surface of the circulation pipe at the output end of the circulation pump, and a dosing pump is connected to the surface of the dosing pipe. A dosing tank is connected to the other end of the dosing pipe. A preliminary aeration structure is fixedly installed inside the storage tank, and an upper grid plate is fixedly installed inside the storage tank. A lower grid plate is fixedly installed inside the storage tank below the upper grid plate. This collection and purification structure can reduce the purification burden on the upper packing layer.

[0004] However, the above-mentioned collection and purification structure still has the following problems: In the above-mentioned collection and purification structure, the reagent and purified water are directly aerated in the purification tower. Since the position of the aeration head in the purification tower is fixed, it is difficult for the aerated gas to come into full and uniform contact with the mixture of reagent and purified water, resulting in poor aeration treatment effect on the waste gas and affecting the purification effect on the waste gas. Utility Model Content

[0005] This invention proposes a collection and purification structure for waste gas spray treatment, which solves the problem in the prior art that the exposed waste gas is difficult to come into full and uniform contact with the mixture of reagent and purified water.

[0006] The technical solution of this utility model is as follows: A collection and purification structure for waste gas spray treatment includes a purification tower. A motor is fixedly installed on the bottom wall of the purification tower. A mixed-liquid aeration zone is provided at the bottom of the inner cavity of the purification tower, and an aeration mechanism is provided in the mixed-liquid aeration zone. The aeration mechanism includes:

[0007] Fixed components, fixed to the bottom wall of the inner cavity of the purification tower;

[0008] The mixing component, driven by a motor, stirs the liquid in the mixed liquid aeration zone.

[0009] The rotating component rotates synchronously with the mixing component;

[0010] The lifting component, in cooperation with the rotating component, moves up and down reciprocally within the fixed component;

[0011] Several aeration components are arranged in a ring around the outside of the fixed component;

[0012] The expansion and lifting components work together to expand and contract the aeration components repeatedly.

[0013] Preferably, the fixing component includes a fixing sleeve, and a plurality of connecting rods that are staggered with the lifting component are fixed to the bottom of the fixing sleeve. A fixing plate is fixed to the bottom end of the connecting rod, and the fixing plate is fixed to the bottom wall of the inner cavity of the purification tower.

[0014] Preferably, the inner sidewall of the fixed sleeve is symmetrically provided with guide grooves, and the lifting component is elastically connected to the fixed sleeve by a spring.

[0015] Preferably, the output end of the motor is fixed with a shaft, and the mixing component includes several outer support rods radially fixed to the top of the shaft, with stirring blades fixed to the outer ends of the outer support rods.

[0016] Preferably, the rotating component includes a turntable, which is fixed on a shaft, and the circumferential surface of the turntable is provided with two helical protrusions that are symmetrical about the axis of the turntable.

[0017] Preferably, the lifting component includes an inner cylinder, and the inner cylinder has symmetrically arranged limiting protrusions on its circumferential surface. The limiting protrusions are slidably arranged in the guide groove inside the fixed sleeve.

[0018] Preferably, two pressure rollers are symmetrically rotatably connected to the top inner side of the inner cylinder. The top end of the spring is fixed to the fixed sleeve, and the bottom end of the spring is fixed to the inner cylinder. The two pressure rollers press against the two spiral protrusions of the turntable under the elastic force of the spring.

[0019] Preferably, the aeration component includes a U-shaped seat, and an aeration head is fixed to the end of the U-shaped seat.

[0020] Preferably, the expansion component includes a first support rod and a second support rod hinged to the first support rod via a pivot.

[0021] Preferably, the purification tower has an exhaust port at the top, a water inlet on one side of the middle section, an air inlet on one side of the bottom section, and an annular air pipe fixed to the bottom wall of the inner cavity of the purification tower. The annular air pipe is connected to the air inlet and is connected to each aeration head through a flexible hose.

[0022] The beneficial effects of this utility model are as follows:

[0023] In this invention, a motor drives the mixing component to rotate, ensuring thorough mixing of the chemicals in the clean water. Simultaneously, the rotation of the mixing component drives the rotating component to rotate synchronously. The rotating component, in conjunction with the lifting component, drives the lifting component to move up and down within the fixed component. This up-and-down movement of the lifting component, in conjunction with the expanding component, causes each aeration component to repeatedly expand and contract, continuously changing the aeration position. Combined with the stirring action of the mixing component, this ensures that the aerated waste gas fully contacts the chemicals mixed in the clean water, improving the waste gas treatment effect. This solves the problem in existing technologies where the aerated waste gas is difficult to uniformly and fully contact the mixture of chemicals and purified water. Attached Figure Description

[0032] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0033] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution: a collection and purification structure for waste gas spray treatment, including a purification tower 1. A motor 4 is fixedly installed on the bottom wall of the purification tower 1. A mixed-liquid aeration zone is provided at the bottom of the inner cavity of the purification tower 1, and an aeration mechanism 3 is provided in the mixed-liquid aeration zone. The aeration mechanism 3 includes a fixed component 31, a mixing component 32, a rotating component 35, a lifting component 36, several aeration components 34, and an expansion component 33. Clean water and waste gas treatment agents are added to the mixed-liquid aeration zone. The motor 4 drives the mixing component 32 to rotate, so that the agents... The mixture can be fully mixed in the clean water. When the mixing component 32 rotates, it can drive the rotating component 35 to rotate synchronously. With the cooperation of the rotating component 35 and the lifting component 36, the lifting component 36 is driven to move up and down within the fixed component 31. When the lifting component 36 moves up and down, it can cooperate with the expansion component 33 to drive each aeration component 34 to reciprocate to expand and contract, thereby continuously changing the aeration position. At the same time, with the stirring of the mixing component 32, the aerated waste gas can fully contact the reagent mixed in the clean water to improve the treatment effect of the waste gas.

[0034] Please see Figure 4 , Figure 5 and Figure 6The fixing component 31 is fixed to the bottom wall of the inner cavity of the purification tower 1. The fixing component 31 includes a fixing sleeve 311. Several connecting rods 312, which are staggered with the lifting component 36, are fixed to the bottom of the fixing sleeve 311. A fixing plate 313 is fixed to the bottom end of the connecting rod 312. The fixing plate 313 is fixed to the bottom wall of the inner cavity of the purification tower 1. Guide grooves 314 are symmetrically opened on the inner side wall of the fixing sleeve 311. The lifting component 36 is elastically connected to the fixing sleeve 311 by a spring 315. The mixing component 32 is driven by the motor 4. The liquid in the mixed liquid aeration zone is stirred. The output end of the motor 4 is fixed with a shaft 41. Both the fixed disk 313 and the fixed sleeve 311 have axial through holes for the shaft 41 to pass through. The mixing component 32 includes several outer support rods 321 that are radially fixed to the top of the shaft 41. The outer end of the outer support rod 321 is fixed with a stirring blade 322. Therefore, when the motor 4 is working, the shaft 41 can drive each outer support rod 321 to rotate, and then the stirring blade 322 at the end of the outer support rod 321 can mix and stir the liquid in the mixed liquid aeration zone.

[0035] The rotating component 35 rotates synchronously with the mixing component 32. The rotating component 35 includes a turntable 351, which is fixed on the shaft 41. Two helical protrusions 352, symmetrically arranged about the axis of the turntable 351, are provided on the circumferential surface of the turntable 351. The lifting component 36, in cooperation with the rotating component 35, reciprocates up and down within the fixed component 31. The lifting component 36 includes an inner cylinder 361, with symmetrically arranged limiting protrusions 362 on its circumferential surface. The limiting protrusions 362 are slidably disposed within the guide groove 314 inside the fixed sleeve 311. Two pressure rollers 363 are symmetrically rotatably connected to the inner top of the cylinder 361. The top end of the spring 315 is fixed to the fixed sleeve 311, and the bottom end of the spring 315 is fixed to the inner cylinder 361. Under the elastic force of the spring 315, the two pressure rollers 363 press against the two spiral protrusions 352 of the turntable 351 respectively. Several aeration components 34 are distributed in a ring on the outside of the fixed component 31. The aeration component 34 includes a U-shaped seat 341, and an aeration head 342 is fixed to the end of the U-shaped seat 341. The expansion component 33 and the lifting component 36 cooperate to raise the aeration component 342. 4. Reciprocating expansion and contraction: The expansion component 33 includes a first support rod 331 and a second support rod 332 hinged to the first support rod 331 via a rotating shaft 333. The top end of the first support rod 331 is hinged to the bottom wall of the inner cylinder 361, and the bottom end of the second support rod 332 is hinged to the fixed disk 313. The U-shaped seat 341 is fixed to the rotating shaft 333. The rotation of the shaft 41 drives the turntable 351 to rotate synchronously. Under the pressure of the spiral protrusion 352 on the inner pressure roller 363 of the inner cylinder 361, and simultaneously under the sliding of the limiting protrusion 362 and the guide groove 314 inside the fixed sleeve 311... Under the dynamic limit, the inner cylinder 361 can move upward within the fixed sleeve 311 against the elastic force of the spring 315, thereby pulling the first support rod 331 upward and causing the aeration head 342 to retract towards the shaft 41. When the turntable 351 rotates until the spiral protrusion 352 is misaligned with the pressure roller 363, the inner cylinder 361 automatically resets under the elastic force of the spring 315. That is, the inner cylinder 361 pushes the first support rod 331, causing the aeration head 342 to expand outward. Through the continuous rotation of the turntable 351, the aeration head 342 can perform reciprocating expansion and contraction movements.

[0036] It should be noted that the purification tower 1 has an exhaust port 11 at the top and a water inlet 12 on one side of the middle section for introducing purification water and waste gas treatment agents. The purification tower 1 above the water inlet 12 is filled with packing material for further purification of the aerated waste gas. The purification tower 1 has an air inlet 13 on one side of the bottom for introducing the waste gas to be treated and aerating it with the mixture of purification water and waste gas treatment in the mixed liquid aeration zone. The bottom wall of the inner cavity of the purification tower 1 is fixed with an annular air pipe 2, which is connected to the air inlet 13. The annular air pipe 2 is connected to each aeration head 342 through a flexible hose (the flexible hose is not shown in the figure) to realize the waste gas transportation to each aeration head 342. Each aeration head 342 completes the aeration treatment of the waste gas with the mixture of purification water and waste gas treatment in the mixed liquid aeration zone.

[0037] The working principle and usage process of this utility model are as follows: Purified water and waste gas treatment agents are added to the mixed liquid aeration zone through the water inlet 12 until the liquid level exceeds the stirring blade 322. When the motor 4 is working, the motor 4 drives the shaft 41 to rotate each of the outer support rods 321. Then, the stirring blades 322 at the ends of the outer support rods 321 mix and stir the liquid in the mixed liquid aeration zone. At the same time, the rotation of the shaft 41 drives the turntable 351 to rotate synchronously. Under the pressure of the spiral protrusion 352 on the inner cylinder 361 pressure roller 363, and under the sliding limit of the limiting protrusion 362 and the inner guide groove 314 of the fixed sleeve 311, the inner cylinder 361 can overcome the spring within the fixed sleeve 311. The spring 315 moves upward, and the inner cylinder 361 pulls the first support rod 331 upward, causing the aeration head 342 to retract towards the shaft 41. When the turntable 351 rotates until the spiral protrusion 352 is misaligned with the pressure roller 363, the inner cylinder 361 automatically resets under the elastic force of the spring 315. That is, the inner cylinder 361 pushes the first support rod 331, causing the aeration head 342 to expand outward. Through the continuous rotation of the turntable 351, the aeration head 342 can perform reciprocating expansion and contraction movements, thereby causing the aeration position of the aeration head 342 to continuously change inward and outward. In conjunction with the stirring of the stirring blade 322, the aerated waste gas can fully contact the reagent mixed in the clean water, thereby improving the treatment effect of the waste gas.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
