Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste gas treatment, and in particular to a waste gas treatment equipment with multi-layer cylindrical fillers. BACKGROUND

[0002] With the acceleration of industrialization, the problem of waste gas emission is becoming increasingly serious. Traditional waste gas treatment technologies such as activated carbon adsorption and catalytic combustion have low efficiency, high cost, and are prone to saturation. The low efficiency of waste gas treatment affects the production efficiency.

[0003] For example, CN114405255A discloses a waste gas treatment equipment for waste incineration, which includes a waste gas treatment equipment body, the waste gas treatment equipment body is fixedly connected with an air inlet pipe, the waste gas treatment equipment body is fixedly installed with an air outlet pipe at the end away from the air inlet pipe, the air outlet pipe is in communication with a gas guide pipe, the gas guide pipe is externally installed with a neutralization equipment, the neutralization equipment is fixedly connected with an exhaust pipe, the inner wall of the exhaust pipe at the end away from the neutralization equipment is sleeved with a filter screen, and the exhaust pipe is fixedly installed with a fan at one end.

[0004] The above-mentioned waste gas treatment equipment body, neutralization equipment, through hole and reaction tube cooperate with each other. The through hole is provided to allow the waste gas from which the particulate matter is removed to enter the interior of the neutralization equipment, thereby achieving the effect of acid-base neutralization reaction. This effectively solves the problem of environmental pollution caused by acidic gases in waste gas. The neutralization of acidic waste gas by the neutralization equipment reduces the harm to the health of workers caused by acidic gases and also reduces the corrosion of mechanical equipment by acidic gases.

[0005] However, the above-mentioned waste gas treatment equipment and existing treatment equipment have the problem that when purifying waste gas, the waste gas is contacted with the neutralizing liquid by spraying or blowing. The spraying method has the defect that part of the waste gas cannot be contacted with the neutralizing liquid. The blowing method causes the waste gas to pass through the neutralizing liquid from bottom to top. Since molecules have a certain tension, the waste gas cannot diffuse in the neutralizing liquid, resulting in incomplete purification.

[0006] Therefore, a new type of waste gas treatment equipment with multi-layer cylindrical fillers can be used to solve the problems of the prior art. SUMMARY

[0007] The present application relates to the technical field of waste gas treatment, and in particular to a waste gas treatment equipment with multi-layer cylindrical fillers.

[0016] Preferably, the linkage mechanism comprises a first protrusion fixedly installed outside the liquid guide pipe, a connecting rod rotatably installed on the first protrusion, a rotating shaft rotatably installed on the outer wall of the rotating pipe, a second protrusion fixedly installed on the end of the rotating shaft away from the rotating pipe, the second protrusion being rotatably connected with the connecting rod, a cam fixedly installed on the side of the rotating shaft close to the rotating pipe, and a pressing roller rotatably installed on the cam and matched with the pushing ring.

[0021] Compared with the prior art, the present application has the following advantages:

[0022] 1. When the waste gas treatment equipment with the multi-layer cylindrical filler is used to neutralize weak acidic substances, the angle changeable stirring blade is used to stir and mix the neutralizing liquid and the waste gas in the purification kettle. Due to the angle change of the stirring blade, the disturbance degree of the neutralizing liquid in the purification kettle is changed, the molecular movement law in the neutralizing liquid is changed, the waste gas is more fully contacted with the neutralizing liquid, and the waste gas purification efficiency is improved.

[0023] 2. When neutralizing weak acidic substances, the waste gas treatment equipment with multi-layer columnar fillers is provided with a liquid guide tube and a one-way tube. During the stirring and mixing process, the centrifugal force generated can be used to throw out the liquid in the liquid guide tube, so that a negative pressure is formed in the liquid guide tube and the rotating tube. Then, in conjunction with the liquid inlet pipe and the liquid inlet bucket, the neutralizing liquid located on the upper part of the purification kettle can be brought into the rotating tube and thrown out through the liquid guide tube, thereby realizing the exchange of liquids between the upper and lower parts, and further improving the waste gas purification efficiency. In addition, the neutralizing liquid in the purification kettle is intermittently sucked into the rotating tube through the liquid inlet bucket, and the waste gas above the partition will be sucked into the rotating tube under the action of negative pressure. Then, the waste gas is squeezed into the liquid guide tube by the neutralizing liquid sucked in next time, thereby realizing the introduction of waste gas. In this way, the amount of waste gas introduced at a single time is stable and the volume is small. After preliminary mixing and neutralization with the neutralizing liquid in the rotating tube and the liquid guide tube, it enters the purification kettle for further neutralization, making the neutralization more thorough.

[0024] 3. When neutralizing weak acidic substances, this waste gas treatment equipment with multi-layer columnar fillers can rotate the stirring blade to a horizontal position, and then cooperate with the sealing mechanism to block the liquid inlet pipe, and absorb the bubbles generated on the liquid surface into the liquid through the air inlet hood, effectively reducing the generation of bubbles during mixing. After the bubbles enter the liquid, they will move from bottom to top, and the movement of the bubbles will drive the movement of the liquid, thereby re-mixing and improving the waste gas purification efficiency. At the same time, by setting a columnar filler enhancement mechanism, the contact time and contact area between the waste gas and the neutralization liquid can be increased, effectively improving the waste gas purification efficiency.

[0025] In summary, the present invention adopts multiple modes to mix the waste gas and neutralizing liquid in the purification kettle, which can not only effectively improve the waste gas purification efficiency and make the purification more thorough, but also increase the contact time and contact area between the waste gas and the neutralizing liquid during the purification process, thereby further improving the waste gas purification efficiency.

DETAILED DESCRIPTION

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0052] Example 1: Reference Figures 1-9, an exhaust gas treatment device with multi-layer columnar packing, comprising a purification tank 1 and a spray tower 53, further comprising a preliminary purifier 5 fixedly mounted on the side of the purification tank 1, and a discharge valve 6 fixedly mounted on the bottom of the purification tank 1;

[0053] When the waste gas passes through the preliminary purifier 5, the particulate matter in the waste gas will be blocked for preliminary filtration. During purification, the waste gas after preliminary filtration is gradually introduced into the purification kettle 1 through the preliminary purifier 5. This can make the waste gas purer, reduce the impact of particulate matter on waste gas purification, and improve the waste gas purification efficiency.

[0054] A partition 41 is provided in the purification kettle 1 to divide the purification kettle 1 into two upper and lower cavities. An electric control valve is installed on the partition 41. When it is opened, the exhaust gas passes through the electric control valve and enters the cavity below the partition 41.

[0055] Two kettle covers 2 are rotatably installed on the top of the purification kettle 1, and a motor 4 is fixedly installed on the top of the purification kettle 1. The driving end of the motor 4 extends into the interior of the purification kettle 1. An air intake cover 9 is installed on the driving end of the motor 4. A rotating tube 10 is fixedly installed on the air intake cover 9. A water absorption mixing component is installed in the middle of the rotating tube 10.

[0056] After being introduced into the purification kettle 1, the exhaust gas will enter the rotating tube 10 through the air inlet hood 9. The bottom of the air inlet hood 9 is flush with the liquid level of the neutralizing liquid. After the rotating tube 10 rotates, the liquid level of the neutralizing liquid will rise and enter the rotating tube 10 from the air inlet hood 9, but it will not affect the entry of the exhaust gas.

[0057] An electric control system 3 is installed outside the purification kettle 1 for controlling the motor 4 and other electrical components inside the purification kettle 1 . The speed and direction of the motor 4 can be changed by setting a program.

[0058] A funnel 18 is fixedly installed inside the rotating tube 10, and the funnel 18 is located at the upper part of the liquid inlet hole. A reducer 7 is fixedly installed outside the purification kettle 1, and the driving end of the motor 4 is connected to the reducer 7. A docking shaft 8 is fixedly installed at the driving end of the reducer 7, and the docking shaft 8 is fixedly connected to the air inlet hood 9.

[0059] The function of the reducer 7 is to reduce the speed of the driving end of the motor 4 to prevent the neutralizing liquid from splashing out due to excessive speed; the docking shaft 8 is used to connect the air intake hood 9 and the driving end of the reducer 7.

[0060] The function of the funnel 18 is to reduce the diameter of the rotating tube 10, so as to increase the flow rate of the liquid in the rotating tube 10, thereby forming a flow rate difference with the liquid below the funnel 18, which will produce an impact effect, which is beneficial to neutralize the dispersion of substances in the liquid, accelerate the flow rate, and provide a higher negative pressure.

[0061] The water absorption and mixing assembly includes a plurality of liquid inlet pipes 12 fixedly mounted on the side of a rotating tube 10. A plurality of liquid inlet holes cooperating with the corresponding liquid inlet pipes 12 are opened on the side of the rotating tube 10. An end of each liquid inlet pipe 12 away from the rotating tube 10 is fixedly connected to a liquid inlet bucket 13. Two elastic reset covers 14 are rotatably mounted on each liquid inlet bucket 13. A sealing mechanism cooperating with the plurality of liquid inlet holes is installed on the rotating tube 10.

[0062] The rotating tube 10 rotates as the driving end of the motor 4 rotates. The rotation of the rotating tube 10 drives the liquid inlet pipe 12 fixedly connected thereto to rotate, thereby driving the liquid inlet hopper 13 to rotate;

[0063] When the rotation speed of the liquid inlet hopper 13 reaches a certain level (the automatic reset force of the elastic reset cover 14 on the liquid inlet hopper 13 is less than the impact force of the liquid on the elastic reset cover 14), the liquid will enter the liquid inlet pipe 12 through the liquid inlet hopper 13, and then enter the rotating tube 10 through the liquid inlet pipe 12, thereby driving the liquid at the upper part of the purification kettle 1 downward.

[0064] The sealing mechanism includes a sealing ring 20 slidably mounted inside the rotating tube 10, a second magnetic ring 19 is fixedly mounted on the bottom of the sealing ring 20, a first magnetic ring 15 cooperating with the second magnetic ring 19 is slidably mounted outside the rotating tube 10, and a pushing ring 16 is fixedly mounted on the bottom of the first magnetic ring 15.

[0065] The movement of the pushing ring 16 drives the first magnetic ring 15 fixedly connected to it to move. The movement of the first magnetic ring 15 drives the second magnetic ring 19 inside the rotating tube 10, which is attracted to the first magnetic ring 15, to move. The second magnetic ring 19 drives the sealing ring 20 fixedly connected to it to move, so that the sealing ring 20 blocks the liquid inlet. At this time, the liquid inlet pipe 12 will not enter the liquid, and the rotating tube 10 keeps rotating at the original speed. At this time, the bubbles on the surface of the neutralized liquid will be brought into the rotating tube 10 and then discharged. Although bubbles will also enter the rotating tube 10 when the liquid inlet hole is not blocked, the amount entering at this time is much smaller than the amount entering after blocking. The purpose of designing the blocking here is to increase the amount of surface neutralized liquid and bubbles entering the liquid interior, which not only improves the bubble treatment efficiency, but also can exchange and mix the upper neutralized liquid and the lower neutralized liquid, so that the neutralized liquid in the purification kettle 1 flows, making the neutralized liquid more uniform, which is beneficial to improving the purification efficiency of the exhaust gas.

[0066] The second embodiment is different from the first embodiment in that: Figures 1-6 、 Figure 10-Figure 22 , a mixing and stirring assembly 11 is installed at the bottom of the rotating tube 10;

[0067] The mixing stirring assembly 11 comprises a liquid inlet box 21 fixedly installed at the bottom of the rotating pipe 10, a mounting rack 22 fixedly installed at the bottom of the liquid inlet box 21, a plurality of connecting pipes 36 rotatably installed on the mounting rack 22, a guide pipe 25 fixedly communicated with each connecting pipe 36, a stirring blade 23 fixedly installed on each guide pipe 25, and a plurality of vibration mechanisms installed in each guide pipe 25.

[0068] The surface of the stirring blade 23 is designed as concave-convex, and when the neutralizing liquid collides with the surface of the stirring blade 23, a vibration wave with a certain intensity is generated, which is beneficial to improve the waste gas purification efficiency. The angle of the stirring blade 23 also affects the collision intensity between the waste gas and the neutralizing liquid molecules, and the optimal angle is forty-five degrees.

[0069] The vibration mechanism comprises a bracket 39 fixedly installed in the guide pipe 25, a vibration piece 37 rotatably installed on the bracket 39, a support block fixedly installed on the bracket 39, an arc-shaped elastic expansion rod 38 fixedly installed between the support block and the vibration piece 37, a spiral groove 40 formed in the inner wall of the guide pipe 25, and a hole corresponding to the vibration piece 37 formed in the guide pipe 25 and the stirring blade 23.

[0070] With the rotation of the stirring blade 23 and the guide pipe 25, the neutralizing liquid enters the guide pipe 25 through the hole in the guide pipe 25 and the stirring blade 23. Since the size of the hole is small, the impact intensity is large, so the vibration piece 37 is driven to rotate around the bracket 39, and the vibration piece 37 is vibrated under the action of the arc-shaped elastic expansion rod 38. In this way, the neutralizing liquid in the guide pipe 25 is vibrated and mixed, the neutralizing liquid and the waste gas molecules are disturbed more frequently, so as to increase the probability of collision between the waste gas molecules and the neutralizing liquid molecules, and effectively improve the waste gas purification efficiency.

[0071] The spiral groove 40 is used to make the neutralizing liquid in the guide pipe 25 flow in a rotating manner, so as to increase the pressure resistance between the substances in the neutralizing liquid, accelerate the molecular motion speed, and thus improve the waste gas purification efficiency.

[0072] Each guide pipe 25 is fixedly communicated with a one-way pipe 24, and the mounting rack 22 is fixedly installed with a plurality of elbow pipes 32, each of which is rotatably connected with a corresponding connecting pipe 36.

[0073] When the liquid guide tube 25 rotates, centrifugal force is generated from the inside out. Under the action of the centrifugal force, the neutralizing liquid inside the liquid guide tube 25 will be thrown out through the one-way tube 24. After the neutralizing liquid in the liquid guide tube 25 is discharged, a negative pressure will be formed. At this time, a negative pressure will be formed in the rotating tube 10 through the connecting tube 36, the curved tube 32 and the liquid inlet box 21. The negative pressure will suck the neutralizing liquid on the surface and the middle into the rotating tube 10, and circulate it to achieve the purpose of exchanging the upper and lower neutralizing liquids and exchanging the middle and lower neutralizing liquids, so that the neutralizing liquid is mixed more evenly in the purification kettle 1, and the weak alkaline neutralizing substance inside the neutralizing liquid is dispersed more evenly, which increases the probability of contact between the waste gas molecules and the weak alkaline neutralizing substance, thereby improving the purification efficiency.

[0074] A motor 33 is fixedly mounted on the mounting frame 22, a gear 34 is fixedly mounted on the driving end of the motor 33, a double-sided gear ring 31 meshing with the gear 34 is rotatably mounted on the mounting frame 22, and a small gear ring 35 meshing with the double-sided gear ring 31 is fixedly mounted on each connecting tube 36, wherein a linkage mechanism cooperating with the push ring 16 is mounted on a portion of the liquid guide tube 25.

[0075] The driving end of the motor 33 rotates to drive the gear 34 fixedly connected to it to rotate, thereby driving the double-sided gear ring 31 meshing with the gear 34 to rotate. The rotation of the double-sided gear ring 31 drives the multiple small gear rings 35 meshing with it to rotate, thereby driving the two connecting tubes 36 to rotate. The connecting tube 36 drives the liquid guide tube 25 to rotate, and the liquid guide tube 25 drives the stirring blade 23 to rotate, thereby changing the angle of the stirring blade 23.

[0076] The linkage mechanism includes a first protrusion 26 fixedly mounted on the outside of the liquid guide tube 25, a connecting rod 27 is rotatably mounted on the first protrusion 26, a rotating shaft 17 is rotatably mounted on the outer wall of the rotating tube 10, a second protrusion 29 is fixedly mounted on the end of the rotating shaft 17 away from the rotating tube 10, the second protrusion 29 is rotatably connected to the connecting rod 27, a cam 28 is fixedly mounted on the side of the rotating shaft 17 close to the rotating tube 10, and a pressure roller 30 that cooperates with the push ring 16 is rotatably mounted on the cam 28.

[0077] As the liquid guide tube 25 rotates, the connecting rod 27 is driven to rotate through the first protrusion 26, and the connecting rod 27 drives the second protrusion 29 to rotate around the rotating shaft 17. The second protrusion 29 drives the rotating shaft 17 to rotate, thereby driving the cam 28 to rotate. The rotation of the cam 28 drives the pressure roller 30 to rotate, so that when the pressure roller 30 contacts the push ring 16, the push ring 16 moves upward, thereby adjusting the position of the push ring 16 to block the liquid inlet hole (only when the stirring blade 23 rotates to a completely horizontal position can the blocking ring 20 completely block the liquid inlet hole).

[0078] During mixing, the angle of the stirring blade 23 is adjusted by the motor 33. The angle can be adjusted during the mixing process to achieve variable angle stirring, or it can be adjusted before stirring and the angle remains unchanged during the mixing process to achieve fixed angle stirring.

[0079] As the angle of the stirring blade 23 changes, the liquid inlet hole will be blocked to varying degrees, and the flow rate of neutralizing liquid entering from the liquid inlet pipe 12 and the flow rate of neutralizing liquid entering from the top of the air inlet cover 9 will automatically change with the degree of blocking.

[0080] A columnar packing enhancement mechanism 43 is installed on each one-way tube 24. The columnar packing enhancement mechanism 43 includes a first enhancement tube 45 fixedly installed on the one-way tube 24, and a second enhancement tube 46 is rotatably installed on the first enhancement tube 45. Diffusion structures are installed in the first enhancement tube 45 and the second enhancement tube 46, and a swing structure matching the second enhancement tube 46 is installed in the purification kettle 1.

[0081] When the neutralizing liquid and exhaust gas are thrown out from the one-way tube 24 (the motor 4 rotates intermittently, so that the neutralizing liquid will be intermittently sucked into the rotating tube 10 through the liquid inlet bucket 13, and the exhaust gas will be sucked in between the two intermittent suctions, so the exhaust gas will be entrained between the two sucked neutralizing liquids, and the exhaust gas will undergo a preliminary mixing reaction with the neutralizing liquid in the rotating tube 10), they will enter the first synergist cylinder 45 and then be discharged through the second synergist cylinder 46.

[0082] A large number of columnar packing enhancement mechanisms 43 are evenly arranged horizontally on the top layer of the spray tower 53 to form a columnar packing treatment layer. When the waste gas enters the spray tower 53 through the bottom of the spray tower 53, some impurities in the waste gas are removed under the spraying action of the spray tower 53, and then the waste gas moves vertically upward and contacts the columnar packing treatment layer. In the columnar packing treatment layer, it contacts the columnar packing enhancement mechanism 43, thereby accelerating the waste treatment efficiency.

[0083] The diffusion structure includes a first outer distribution ring 47 fixedly installed in the first enhancement tube 45 or the second enhancement tube 46, a secondary distributor 48 is fixedly installed on the first outer distribution ring 47 through a plurality of connecting columns, a second outer distribution ring 49 is fixedly installed on the secondary distributor 48 through a plurality of arc-shaped connecting plates, an inner distribution ring 52 is fixedly installed on the secondary distributor 48, a distribution bar 50 is fixedly installed between the inner distribution ring 52 and each connecting column, and a plurality of distribution columns 51 are fixedly installed on each distribution bar 50.

[0084] The distribution strips 50 and the distribution columns 51 in the first and second booster tubes 45 and 46 will divert the exhaust gas and the neutralizing liquid, allowing the exhaust gas and the neutralizing liquid to diffuse more widely, further increasing the contact area between the exhaust gas and the neutralizing liquid, and promoting the reaction between the exhaust gas and the neutralizing liquid.

[0085] The swing structure includes multiple magnetic pole plates 44 fixedly installed on the outside of the second booster tube 46, a magnetic gear ring 42 matched with the multiple magnetic pole plates 44 is fixedly installed inside the purification kettle 1, and a swing spring coil is fixedly installed at the rotating connection part between the second booster tube 46 and the first booster tube 45.

[0086] Since the magnetic gear ring 42 and the magnetic pole plate 44 are in relative motion, the attractive force between the magnetic gear ring 42 and the magnetic pole plate 44 is a variable force. As the second booster tube 46 rotates, the suction force between the magnetic pole plate 44 and the magnetic gear ring 42 decreases. When the suction force is less than the elastic force of the swing spring coil, the second booster tube 46 will be reversed and reset under the action of the swing spring coil, which will generate a certain degree of vibration, drive the distribution column 51 to shake, accelerate the molecular movement, and improve the purification efficiency.

[0087] The specific operating steps of this device are as follows:

[0088] First, the waste gas passes through the bottom of the spray tower 53 and enters the spray tower 53. Under the spraying action of the spray tower 53, some impurities in the waste gas are removed. Then the waste gas moves vertically upward and contacts the columnar packing treatment layer. In the columnar packing treatment layer, it contacts the columnar packing enhancement mechanism 43 to speed up the waste treatment efficiency.

[0089] After being treated by the columnar packing treatment layer, the exhaust gas passes through the preliminary purifier 5 and enters the upper part of the partition 41 in the purification kettle 1. After being left in the upper cavity of the purification kettle 1 for a certain period of time, the degree of molecular disturbance is reduced and the distribution is uniform. Then, the electric control valve is opened to guide the exhaust gas into the lower cavity.

[0090] Start the motor 4, the motor 4 rotates through the reducer 7 to drive the docking shaft 8 to rotate, thereby driving the rotating tube 10 and the air inlet cover 9 to rotate, the rotating tube 10 rotates to drive the liquid inlet pipe 12 fixedly connected to it to rotate, thereby driving the liquid inlet bucket 13 to rotate;

[0091] When the rotation speed of the liquid inlet hopper 13 reaches a certain level (the automatic reset elastic force of the elastic reset cover 14 on the liquid inlet hopper 13 is less than the impact force of the liquid on the elastic reset cover 14), the liquid will enter the liquid inlet pipe 12 through the liquid inlet hopper 13, and then enter the rotating tube 10 through the liquid inlet pipe 12, thereby driving the liquid at the upper part of the purification kettle 1 downward, and the motor 4 rotates intermittently, so that the neutralization liquid will be intermittently sucked into the rotating tube 10 through the liquid inlet hopper 13. Between the two intermittent suctions, the exhaust gas will be sucked in. Therefore, the exhaust gas will be entrained between the two inhaled neutralization liquids, and the exhaust gas will undergo a preliminary mixing reaction with the neutralization liquid in the rotating tube 10;

[0092] As the stirring blade 23 and the liquid guide tube 25 rotate, the neutralizing liquid enters the liquid guide tube 25 through the holes in the stirring blade 23. Since the holes are small in size, the impact force generated is large, which drives the vibrating plate 37 to rotate around the bracket 39. Under the action of the arc-shaped elastic telescopic rod 38, the vibrating plate 37 vibrates. At the same time, under the action of the spiral groove 40, the neutralizing liquid entering the liquid guide tube 25 is caused to flow in a rotating manner.

[0093] When the liquid guide tube 25 rotates, centrifugal force is generated from the inside out. Under the action of the centrifugal force, the neutralizing liquid inside the liquid guide tube 25 is thrown out through the one-way tube 24. After the neutralizing liquid in the liquid guide tube 25 is discharged, negative pressure is formed. At this time, negative pressure is formed in the rotating tube 10 through the connecting tube 36, the elbow 32 and the liquid inlet box 21. The negative pressure draws the neutralizing liquid on the surface and the middle into the rotating tube 10, thus circulating.

[0094] The driving end of the motor 33 rotates to drive the gear 34 fixed to it, thereby driving the double-sided gear ring 31 meshing with the gear 34 to rotate. The rotation of the double-sided gear ring 31 drives the multiple small gear rings 35 meshing with it to rotate, thereby driving the two connecting tubes 36 to rotate. The connecting tube 36 drives the liquid guide tube 25 to rotate. The liquid guide tube 25 drives the stirring blade 23 to rotate, thereby changing the angle of the stirring blade 23.

[0095] As the liquid guide tube 25 rotates, the connecting rod 27 is driven to rotate via the first protrusion 26. The connecting rod 27 drives the second protrusion 29 to rotate around the rotating shaft 17. The second protrusion 29 drives the rotating shaft 17 to rotate, thereby driving the cam 28 to rotate. The rotation of the cam 28 drives the pressure roller 30 to rotate. When the pressure roller 30 abuts against the push ring 16, the push ring 16 moves upward, thereby adjusting the position of the push ring 16 to block the liquid inlet hole.

[0096] As the angle of the stirring blade 23 changes, the liquid inlet hole will be blocked to varying degrees, and the flow rate of the neutralizing liquid entering from the liquid inlet pipe 12 and the flow rate of the top neutralizing liquid entering from the air inlet cover 9 will automatically change with the degree of blocking;

[0097] When the neutralization liquid and exhaust gas are thrown out from the one-way tube 24, they will enter the first synergist tube 45 and then be discharged through the second synergist tube 46. Since the magnetic gear ring 42 and the magnetic pole plate 44 are in relative motion, the attractive force between the magnetic gear ring 42 and the magnetic pole plate 44 is a changing force. As the second synergist tube 46 rotates, the suction force between the magnetic pole plate 44 and the magnetic gear ring 42 becomes smaller. When the suction force is less than the elastic force of the swing spring coil, the second synergist tube 46 will be reversed and reset under the action of the swing spring coil, which will generate a certain degree of vibration, which will drive the distribution column 51 to shake, accelerate the molecular movement, and improve the purification efficiency.
