Description

Technical Field

[0001] This invention relates to the field of water purification equipment technology, specifically to an ozone contact treatment tower for treating odors in water. Background Technology

[0002] With accelerated urbanization and the spread of industrial pollution, drinking water sources face increasingly severe odor pollution problems. Odors in water mainly originate from algal metabolites (such as geosmin and 2-methylisoborneol), byproducts of microbial activity, and volatile organic compounds from industrial wastewater discharge. These substances not only directly affect the sensory quality of drinking water and reduce users' trust in water supply safety, but some odor-causing substances may also pose potential health risks. Therefore, efficient removal of odors from water has become one of the core technological requirements in the water treatment field. Ozone oxidation technology, due to its advantages such as strong oxidation capacity, fast reaction speed, and no secondary pollution (the final product is oxygen), is widely used in water odor treatment. Its core principle is that ozone reacts with odor-causing substances in water through oxidation, decomposing large molecular odor substances into odorless small molecular compounds, thereby achieving water purification.

[0003] Existing ozone contact treatment equipment still faces several bottlenecks in practical applications: On the one hand, the contact efficiency between ozone and the water to be treated is low. Traditional equipment often uses fixed nozzles to spray water and air intake in one direction, making it difficult for the gas and liquid phases to form sufficient turbulent mixing. This results in some ozone escaping without participating in the reaction, which not only reduces ozone utilization but also increases the cost of exhaust gas treatment. On the other hand, the gas-liquid mixture is prone to forming large bubbles or liquid masses during the reaction process, increasing the mass transfer resistance of ozone in the liquid, resulting in incomplete oxidation reaction and difficulty in achieving efficient removal of odor substances.

[0004] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention

[0005] The purpose of this invention is to provide an ozone contact treatment tower for treating odors in water, in order to solve the problems mentioned in the background. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an ozone contact treatment tower for treating odors in water, comprising a mounting base, a spray tower fixedly mounted on the upper end of the mounting base, a water inlet pipe connected to the upper end of the spray tower, a drive motor fixedly mounted on the bottom inside the spray tower, a rotating rod connected to the output end of the drive motor, an air inlet ring fixedly mounted inside the spray tower, a spiral air inlet provided at equal angles inside the air inlet ring, a connecting sleeve fixedly mounted inside the spray tower, and symmetrical water inlet nozzles rotatably mounted on the upper end of the spray tower; The oscillating spraying mechanism is respectively installed inside the upper end of the spray tower and on the air inlet ring. The oscillating spraying mechanism is used to improve the feeding efficiency of the spiral air inlet and the water inlet nozzle. A mixing and crushing mechanism is installed inside the connecting sleeve, and is used to further disperse and mix the gas-liquid mixture inside the spray tower.

[0007] Preferably, the oscillating spraying mechanism includes a rotating wheel, which is fixedly mounted on a rotating rod. The surface of the rotating wheel is provided with a sliding groove that undulates up and down, and the rotating wheel is disposed in the inner diameter of the air intake ring.

[0008] Preferably, the oscillating spraying mechanism includes a connecting block, one end of which is mounted on the inside of the air intake ring via a rotating shaft, and the other end of which is fixedly mounted with an abutment rod, which cooperates with a sliding groove.

[0009] Preferably, the upper end of the rotating shaft of the connecting block is fixedly connected to the spiral air inlet, and the spiral air inlet and the connecting block are in an "L" shape when viewed from the front.

[0010] Preferably, the oscillating spraying mechanism further includes a rotating disk, which is rotatably mounted on the upper end of the spray tower. The rotating disk is fixedly connected to the top end of the rotating rod, and a movable block is elastically slidably mounted on the rotating disk, with the movable block located at the eccentric position of the rotating disk.

[0011] Preferably, a movable sleeve rod is rotatably mounted on the upper end of the movable block, and a connecting rod is sleeved inside the movable sleeve rod. The two ends of the connecting rod are respectively fixedly mounted on symmetrical water inlet nozzles.

[0012] Preferably, the mixing and crushing mechanism includes a movable ring, which is elastically slidably mounted in a groove on the inner wall of the connecting sleeve via a protrusion. A second connecting rod is fixedly mounted on the protrusion, and the movable ring is symmetrically arranged vertically via the second connecting rod.

[0013] Preferably, the movable ring has a support rod arranged at equal angles inside, the support rod has teeth arranged at equal intervals, the protrusion has a magnet inside, and the protrusion is arranged at equal angles on the outer wall of the movable ring.

[0014] Preferably, the mixing and crushing mechanism further includes a cutting collar, which is rotatably installed inside the connecting sleeve via a fixed mounting block on the outer wall. The connecting sleeve has symmetrical cutting components installed inside, and the cutting components have multiple sets of teeth distributed at equal angles.

[0015] Preferably, the cutting element is fixedly connected to the rotating rod, the second tooth is staggered with the first tooth, the docking block is L-shaped when viewed from the front, a ring is fixedly installed on the upper end of the docking block, and magnets with the same magnetism as the inside of the protrusion are arranged at equal angles inside the ring. The rotation trajectory of the ring is located directly below the protrusion and the positions of the internal magnets are opposite.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. The equipment uses a drive motor to simultaneously drive a rotating rod to activate the oscillating structure at the air intake ring and water inlet nozzle, achieving an innovative "bidirectional gas-liquid oscillation" contact mode: at the air intake end, the undulating sliding grooves on the surface of the rotating wheel cooperate with the abutment rod, causing the connecting block to reciprocate around the axis, thereby causing the spiral air intake fixed to the connecting block to produce periodic angular changes. This oscillation method creates a dynamic spiral airflow when ozone passes through the spiral air intake, breaking the airflow stratification problem of traditional fixed air intake and increasing the contact area between ozone and water; at the same time, the spiral structure itself can enhance airflow turbulence, making the ozone bubbles diffuse over a wider range in the water; Furthermore, at the water inlet, the rotating rod drives the rotating disk to rotate, and the movable block at its eccentric position is linked to the connecting rod via a movable sleeve rod, driving the symmetrically arranged water inlet nozzles to reciprocate and oscillate while spraying. Compared to fixed nozzles, the oscillating spraying allows the water to be treated to form a uniform water film coverage within the spray tower, avoiding the problems of localized "waterless areas" or "excessively thick water films," ensuring full contact between the ozone flow and the water film. The synergistic effect of the bidirectional oscillation of gas and liquid creates a complex turbulent mixing state between the gas and liquid phases within the spray tower, significantly reducing mass transfer resistance and providing sufficient reaction conditions for ozone oxidation of odor substances.

[0017] 2. To address the issue of "easy agglomeration of gas-liquid mixtures" in traditional equipment, this equipment incorporates a multi-stage mixing and crushing structure within the connecting sleeve: First, the rotating rod drives the cutting component to rotate synchronously. The second tooth on the cutting component interlocks with the first tooth on the movable ring support rod, forming a "shearing and crushing zone" to initially cut the rising gas-liquid mixture, breaking larger bubbles and liquid clumps into smaller particles, thus increasing the contact interface between ozone and odor substances. Second, the movable ring is elastically slidably mounted on the inner wall of the connecting sleeve via a protrusion. The magnet inside the protrusion and the same-pole magnet on the ring generate a periodic repulsive force, causing the movable ring to vibrate at high frequency in the vertical direction. This vibration further disrupts the agglomeration tendency of gas-liquid particles while accelerating the dissolution and diffusion of ozone in the liquid, resulting in a more complete oxidation reaction. Meanwhile, the symmetrically arranged movable rings and cutting components form a double crushing and mixing zone, which allows the gas-liquid mixture to undergo multiple shearing and vibration processes during its ascent. This effectively solves the problems of "excessively high local ozone concentration and incomplete reaction in some areas," ensuring that odor substances in the water can be fully oxidized and decomposed, and significantly improving the odor removal rate.

[0018] 3. The oscillation amplitude and mixing intensity of the equipment can be flexibly controlled by adjusting the speed of the drive motor. When the odor concentration of the source water is high, the motor speed can be increased to enhance the gas-liquid oscillation frequency and crushing intensity, thereby strengthening the oxidation effect. When the water quality is good, the speed can be reduced to save energy. This adjustability allows the equipment to adapt to the treatment needs of different water sources and different levels of odor pollution, enhancing the practical value of the equipment.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-7 The present invention provides a technical solution: an ozone contact treatment tower for treating odor in water, comprising a mounting base 1, a spray tower 2 fixedly mounted on the upper end of the mounting base 1, a water inlet pipe 3 connected to the upper end of the spray tower 2, a drive motor 4 fixedly mounted inside the bottom end of the spray tower 2, a rotating rod 5 connected to the output end of the drive motor 4, an air inlet ring 6 fixedly mounted inside the spray tower 2, a spiral air inlet 7 set at equal angles inside the air inlet ring 6, a connecting sleeve 8 fixedly mounted inside the spray tower 2, and left and right symmetrical water inlet nozzles 9 rotatably mounted on the upper end of the spray tower 2; The oscillating spraying mechanism is installed inside the upper end of the spray tower 2 and on the air inlet ring 6. The oscillating spraying mechanism is used to improve the feeding efficiency of the spiral air inlet 7 and the water inlet nozzle 9. The mixing and crushing mechanism is located inside the connecting sleeve 8. The mixing and crushing mechanism is used to further disperse and mix the gas-liquid mixture inside the spray tower 2.

[0023] As one embodiment of the present invention, the oscillating spraying mechanism includes a rotating wheel 10, which is fixedly mounted on a rotating rod 5. The surface of the rotating wheel 10 is provided with a sliding groove 11 that undulates up and down, and the rotating wheel 10 is disposed in the inner diameter of the air intake ring 6.

[0024] In one embodiment of the present invention, the oscillating spraying mechanism includes a connecting block 12. One end of the connecting block 12 is mounted on the inside of the air intake ring 6 via a rotating shaft, and the other end of the connecting block 12 is fixedly mounted with an abutment rod 13, which cooperates with the sliding groove 11.

[0025] In one embodiment of the present invention, the upper end of the rotating shaft of the connecting block 12 is fixedly connected to the spiral air inlet 7, and the spiral air inlet 7 and the connecting block 12 are in an "L" shape when viewed from the front.

[0026] As one embodiment of the present invention, the oscillating spraying mechanism further includes a rotating disk 14, which is rotatably mounted on the upper end of the spray tower 2. The rotating disk 14 is fixedly connected to the top end of the rotating rod 5. A movable block 15 is elastically slidably mounted on the rotating disk 14, and the movable block 15 is located at the eccentric position of the rotating disk 14.

[0027] In one embodiment of the present invention, a movable sleeve rod 16 is rotatably mounted on the upper end of the movable block 15, and a connecting rod 17 is sleeved inside the movable sleeve rod 16. The two ends of the connecting rod 17 are respectively fixedly mounted on the symmetrical water inlet nozzles 9.

[0028] The drive motor 4, installed at the bottom of the spray tower 2, starts running, and its output drives the rotating rod 5 to rotate at high speed in the vertical direction. The rotating rod 5, as the core power transmission component, synchronously realizes power transmission: first, it drives the rotating wheel 10 fixed in the middle of the rod to rotate, providing power for the air inlet swing structure; second, it drives the rotating disk 14 at the top of the rod to rotate, providing power for the water inlet swing structure.

[0029] In one embodiment of the present invention, the mixing and crushing mechanism includes a movable ring 18, which is elastically slidably installed in a groove on the inner wall of the connecting sleeve 8 via a protrusion 1801. A connecting rod 19 is fixedly installed on the protrusion 1801, and the movable ring 18 is symmetrically arranged vertically via the connecting rod 19.

[0030] In one embodiment of the present invention, a support rod 20 is provided at equal angles inside the movable ring 18, and teeth 2001 are provided at equal intervals on the support rod 20. A magnet is provided inside the protrusion 1801, and the protrusion 1801 is provided at equal angles on the outer wall of the movable ring 18.

[0031] As one embodiment of the present invention, the mixing and crushing mechanism further includes a cutting collar 21. The cutting collar 21 is rotatably installed inside the connecting sleeve 8 by fixing the docking block 22 on the outer wall. The connecting sleeve 8 has a vertically symmetrical cutting member 23 fixedly installed inside, and multiple sets of teeth 2301 are distributed at equal angles on the cutting member 23.

[0032] In one embodiment of the present invention, the cutting member 23 is fixedly connected to the rotating rod 5, the second tooth 2301 and the first tooth 2001 are staggered, the docking block 22 is L-shaped when viewed from the front, and a ring 24 is fixedly installed on the upper end of the docking block 22. The ring 24 has magnets with the same magnetism as the inside of the protrusion 1801 arranged at equal angles inside. The rotation trajectory of the ring 24 is located directly below the protrusion 1801 and the positions of the internal magnets are opposite.

[0033] Under the action of the drive motor 4, the rotating rod 5 drives the cutting piece 23 to rotate at high speed. The teeth 2301 distributed at equal angles on the cutting piece 23 and the teeth 2001 on the internal support rod 20 of the movable ring 18 form an interlaced shearing structure.

[0034] Working principle: The initial power for the equipment operation is provided by the drive motor 4 at the bottom of the spray tower 2. After the motor starts, it drives the vertically set rotating rod 5 to rotate at a constant speed. The rotating rod 5 serves as the core power hub, synchronously transmitting a single power source to three key functional areas.

[0035] After the power transmission is in place, the air intake and water intake systems start synchronously and form a dynamic contact environment. On the air intake side, when the rotating wheel 10 rotates in the inner diameter of the air intake ring 6, the sliding groove 11 on its surface forms a sliding fit with the abutment rod 13 at the end of the connecting block 12, pushing the connecting block 12 to rotate back and forth by ±30° around the axis of rotation of the inner wall of the air intake ring 6. Since the connecting block 12 and the spiral air intake 7 are fixedly connected in an "L" shape, the spiral air intake 7 swings synchronously with the connecting block 12, so that when the ozone gas passes through, a spiral airflow with a periodically changing direction is formed, which not only expands the diffusion range but also breaks the bubble aggregation. On the water intake side, when the rotating disk 14 rotates, the movable block 15 at its eccentric position makes a circular motion. Through the linkage between the movable sleeve rod 16 and the connecting rod 17, it drives the left and right symmetrical water intake nozzles 9 to swing back and forth by ±45°. After the odor-containing water is transported to the nozzles through the water intake pipe 3, it forms a water film that evenly covers the cross-section of the spray tower 2 with a fan-shaped swing trajectory. The bidirectional oscillation of gas and liquid allows the ozone gas flow and water film to form sufficient turbulent mixing in the upper part of the spray tower 2, which greatly improves the initial contact area and mass transfer efficiency.

[0036] Simultaneously, the teeth 2301 on the high-speed rotating cutting piece 23 in the middle of the spray tower 2 interlock with the teeth 2001 on the internal support rod 20 of the movable ring 18, shearing larger bubbles and liquid clusters in the mixture into tiny particles, significantly increasing the contact interface between ozone and odor substances. The second stage is vibration dispersion. The cutting collar 21 is linked to the rotating rod 5 through the docking block 22, and the ring 24 fixed at its upper end rotates together. The magnet in the ring 24 and the same-pole magnet in the protrusion 1801 on the outer wall of the movable ring 18 generate a periodic repulsive force, pushing the movable ring 18 to vibrate at high frequency and micro-amplitude along the groove of the connecting sleeve 8, further destroying the aggregation tendency of tiny particles, accelerating ozone dissolution and diffusion, and ensuring a more complete oxidation reaction. In the entire process, the concentration of power transmission, the dynamism of gas-liquid contact, and the multi-stage mixing and crushing form an organic whole, effectively solving the problems of insufficient gas-liquid contact and low ozone utilization in traditional equipment, and ultimately achieving the core goal of efficiently removing odors from water.
