Description

Technical Field

[0001] This invention relates to the field of wastewater deodorization, and in particular to a deodorization device for wastewater treatment. Background Technology

[0002] Wastewater treatment plants and wastewater treatment stations in food processing and slaughtering enterprises often produce large amounts of odorous gases containing hydrogen sulfide, ammonia, and other volatile substances. Currently, wet scrubbing towers are widely used in industry to wash and purify these odorous gases.

[0003] Existing, well-known wet scrubbing deodorization equipment typically relies on a water pump to pressurize the water distribution system, spraying the absorbent liquid through fine atomizing nozzles at the end of the pipe, creating a counter-current contact with the rising odor. However, the absorbent liquid in wastewater treatment environments (even after circulation and sedimentation) inevitably contains fine particulate matter, biofilm fragments, or scaling substances. These impurities easily accumulate at the narrow aperture of the atomizing nozzles, leading to frequent nozzle clogging, creating spray blind spots, and severely reducing the gas-liquid contact area and deodorization efficiency.

When used as a secondary output structure, the rotational force generated in the central part can cooperate with the rotating motor to provide a certain level of torque, and the wind turbine blades, driven by the rotating motor, can also generate a propulsive force to lift the odorous gas.

[0016] This invention uses a rotating rod as the main shaft, which can also drive the scraper at the bottom to run continuously; thus avoiding the secondary odor generated by the anaerobic fermentation of the sludge at the bottom. Attached Figure Description

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] In the attached diagram, all identical reference numerals refer to the same components.

[0020] In a first embodiment, the present invention provides a deodorization device for wastewater treatment, such as... Figure 1 As shown, the core transmission component of the equipment is the rotating rod 100, which mainly rotates within the sealed chamber 200. In actual working conditions, a hollow tube shaft made of titanium alloy can be used, and the surface can be coated with tungsten carbide or ceramic coating for corrosion protection, so that it can be used in a corrosive environment with high concentration of acidic gas while ensuring extremely high torsional rigidity. The sealed chamber 200 is mainly an external pressure-bearing shell for violent gas-liquid multiphase flow reactions and physical isolation. It can be made of glass fiber reinforced plastic, with an internal sealed design, and can be lined with a carbon steel pressure-bearing shell of polytetrafluoroethylene or polyurea elastomer. It is suitable for working conditions that can withstand slight positive or negative pressure fluctuations. One method of providing transmission for the rotating rod 100 is a rotating assembly 300. The rotating assembly 300 is an aerodynamic mechanism that is directly mounted on the rotating rod 100 and moves circumferentially thereafter. It is used to guide airflow or generate an endogenous rotating wind field. Its structure includes a long-lasting self-lubricating bearing and a multi-stage mechanical dynamic sealing mechanism, as well as a multi-bladed centrifugal impeller assembly based on a hydrodynamic airfoil. It is driven by an airflow pipe 310, that is, driven by the airflow velocity of the externally transported odorous gas to be treated. The airflow pipe 310 can be a rigid polyvinyl chloride large-diameter straight air guide pipe or a silicone hose with a guide spiral pattern on the inner wall. The centrifugal cup 400 is the core atomizing element of the whole system that carries the liquid and converts it into a high-speed jet through centrifugal acceleration. The side surface of the centrifugal cup 400 is cylindrical, and the bottom can be a horizontal or inverted conical centrifugal disk. The liquid is uniformly accelerated during the centrifugal climbing process on the inner wall. A crucial water-retaining ring 500 is designed on the outer side of the centrifuge cup 400. This ring is used to intercept and further agitate the high-speed liquid flow. Its structure is a metal ring formed by high-precision CNC stamping, with a hardened inner wall surface to resist cavitation erosion from water droplets. Subsequently, the surface is machined with rough textures or regularly raised water-retaining bosses. Corresponding to the water-retaining ring 500 is a water-splashing groove 410 on the surface of the centrifuge cup 400, used to guide the orderly overflow of liquid. Its structure can be a gradually expanding overflow groove, a high-density rectangular array of cuts, etc. Figure 1-2 As shown, this embodiment provides a simple spiral-shaped water-spinning tank 410 so that the water inside the centrifuge cup 400 is ejected in a water jet shape. Above the centrifuge cup 400 is a water supply component 600 with a conventional water circulation pipe. Its outlet pipe has a large diameter and can be directly installed on the upper part of the centrifuge cup 400 to discharge water into the interior. Therefore, the water output end will not be blocked during the water input process.

[0021] Within the centrifuge cup 400, the liquid is subjected to a powerful centrifugal force, forming an extremely thin liquid film that adheres to the wall and climbs towards the outer edge. When the liquid film reaches the water-spraying tank 410, due to the contraction and guidance of the flow channel, the liquid is forcibly divided and converged into multiple slender liquid columns with extremely high initial velocities. These columns then impact the strip-shaped protrusions of the water-blocking ring 500. This intense mechanical impact instantly imparts a large amount of local shear energy to the fluid, forcing the internal cohesive tension network of the liquid to completely collapse, achieving secondary mechanical tearing. This composite fragmentation mode can stably control the average particle size of the atomized particles to a certain level without relying on extremely high rotational speeds. This reduces pipe blockage, greatly improves the uniformity of spraying and gas-liquid contact, and significantly saves on the amount of deodorizing liquid added.

[0022] At the same time, the airflow pipe 310 is transmitted to the rotating rod 100 through the rotating component 300. As the gas moves upward, it is guided by the rotating component 300 and generates initial momentum, forming a rotating flow field similar to a cyclone. This creates a shear collision with the ejected droplets, thereby improving the deodorization and absorption efficiency.

[0023] Specifically, during the equipment startup and continuous operation process, the externally supplied water source or circulating water containing microorganisms and chemical agents is continuously and evenly injected into the middle of the centrifugal cup 400, which is in a high-speed rotating state, through the outlet 610 of the water supply component 600. At the moment of contact with the bottom of the cup, the liquid rapidly diffuses outward under the dual coupling effect of the centrifugal force field and its own gravity, and spreads along the inner wall of the centrifugal cup 400 to form a liquid film. As the rotating rod 100 rotates circumferentially at a constant or frequency-adjusted angular velocity, the liquid film is continuously pushed toward the physical edge of the centrifuge cup 400. At the edge, the liquid is forced to flow into the radially distributed strip-shaped water-throwing tank 410, where the liquid film is compressed and transformed into hundreds of high-speed ejected fine liquid streams. Simultaneously, a high-pressure blower introduces odorous gas through the airflow pipe 310. Guided and disturbed by the rotating component 300, the airflow creates a strong upward vortex wind field within the sealed chamber 200. The liquid flow ejected by the water-splashing tank 410 undergoes initial aerodynamic stretching as it crosses the gap between the cup body and the water-blocking ring 500. Then, these liquid flows directly impact the strip-shaped protruding water-blocking ring 500 at extremely high relative speed. At the moment of impact, the fluid breaks into a dense mist to form a mist layer at the top, which tangentially collides with the odor rising from the bottom. The active ingredients in the deodorizing liquid quickly capture and neutralize the odor molecules, completing the initial gas-liquid combination.

[0024] Furthermore, the wind turbine blade 320 is mainly a curved streamline blade based on aerodynamic optimization. Its core function is to forcibly twist the macroscopic movement of the airflow from radial to axial, so that the airflow pipe 310 assists the rotating rod 100 in its action. The enclosure 330 is the shell assembly that covers the wind turbine blade 320, serving a dual function as a stator and fairing. It strictly defines the flow field boundary and protects the internal blades. The bottom can be a rigid shell injection-molded from a high-rigidity material such as polycarbonate or ABS engineering plastic, while the sidewalls are a composite shock-absorbing shell with a high-polymer damping material lined with flexible silicone walls. For gas exhaust, such as... Figure 3 As shown, the top of the covering 330 can be an open vent 340, so that the gas mainly moves upward. At this time, the airflow is mainly cyclone-like, which is consistent with the action pattern described above.

[0025] In another embodiment, under more practical working conditions, in order to reduce the liquid accumulation inside the covering 330 and reduce the impact on the internal airflow, a top plate 332 and a bottom plate 333 are also provided on the covering 330. The top plate 332 is an air distribution and flow equalization component on the upper layer of the covering 330. At this time, the vents 340 are arranged on the surface of the top plate 332, and their arrangement can be a honeycomb hexagonal guide mesh or a louvered inclined grille, forcing the airflow to be ejected at a specific elevation angle, such as... Figure 4 As shown, this embodiment provides a corresponding example of a perforated structure; the drain groove 331 set at the bottom plate 333 serves as the outflow direction of the liquid, and the bottom plate 333 is inclined towards the drain groove 331, so that the internal liquid is discharged from the drain groove 331.

[0026] The airflow pipe 310 is located at the axis of the wind turbine blade 320 and connected to the side surface of the cover 330, so that the airflow is injected along the inner wall of the cover 330 in a tangential direction. This injection method makes full use of the kinetic energy of the airflow and directly generates a tangential impulse on the outer edge of the wind turbine blade 320. The design of its top vent 340 facing the centrifugal cup 400 ensures that the rectified spiral air column can be blown accurately and directionally towards the atomization and breaking zone above, realizing the composite momentum exchange of "air blowing water".

[0027] Specifically, when the high-pressure blower starts, the odorous gas is propelled at high speed along the airflow pipe 310 under the pressure difference. Since the inlet pipe is misaligned with the rotor's central axis, the high-speed airflow rushes into the annular sidewall of the covering 330 at a tangential angle. The gas is forced to rotate forward in a spiral shape along the inner wall surface within the confined annular cylindrical space. At the same time, the wind turbine blades 320 are compressed by hydrodynamic force and rotate accordingly. The airflow passing through the wind turbine blades 320 is further smoothed and rectified under the guidance of their airfoil surfaces, and the dynamic pressure is converted into static pressure, making the flow field more stable.

[0028] As the water at the bottom flows along the sloping base plate 333, it drips safely down the drain trough 331 to the anti-sludge funnel area at the bottom. The clean airflow, blocked by the solid base plate 333, can only choose to turn upwards. Under the effect of the equalizing chamber, the airflow accumulates pressure and then evenly penetrates the densely perforated ventilation openings 340 on the top plate 332. When the ventilation openings 340 on the top plate 332 are Venturi-shaped jet hole structures, the airflow will be accelerated twice in the instant it passes through the extremely small aperture, forming thousands of micro jets. These jets are like an upward air curtain, rushing towards the mist area. Because the aperture at the top plate 332 is set with a large pressure, the mist is less likely to drip from the top into the interior.

[0029] For example, the impact tooth 510 mentioned above can be a specific structure such as an arc-shaped edge tooth, a square protrusion, or a sharp serration.

[0030] In another embodiment, after efficient gas-liquid mixing, a large number of mixed droplets carrying dust, oil, and reaction precipitates are inevitably generated. The contaminants mainly fall into the funnel-shaped section of the sealed chamber 200. A scraper assembly 700 is provided at the bottom, which includes a connecting seat 730 and a mounting seat 740. An inclined scraper 710 is installed at an angle between the connecting seat 730 and the mounting seat 740, directly contacting and pushing away the contaminants from the inner wall of the funnel-shaped section. Multiple inclined scrapers 710... The upper part may be provided with an annular connector 720520 to connect multiple inclined scraper blades 710 into a frame-like overall structure. The annular connector 720520 is inclined towards the center, so that when liquid drips from the inner wall of the sealed chamber into the funnel-shaped structure area, it slides towards the center. A reduction mechanism is also provided between the high-speed input end of the rotating rod 100 and the connecting seat 730 of the scraper assembly 700. This reduction mechanism significantly reduces the rotational angular velocity transmitted to the scraper assembly 700 and amplifies the output torque through the transmission ratio. Figure 1 The speed reduction mechanism is set on the rotating rod 100 and can be in the form of a hollow shaft planetary gear reducer, a coaxial dual-shaft transmission reducer, etc.

[0031] Specifically, after the gas-liquid washing process described above, the droplets containing impurity particles that have lost their suspension power, as well as the liquid flow that has condensed and adhered to the inner wall of the chamber, all slide down to the bottom of the equipment under the pull of gravity. Since the bottom is a typical funnel shape, solid-liquid mixtures with different densities initially converge on the inclined surface, and the denser solid particles preferentially adhere to the inclined wall of the funnel. Next, the scraper assembly 700, which is installed to fit the bottom contour of the sealed chamber 200, begins to rotate at a constant speed around the inner conical surface of the funnel under the drive of the reduction mechanism of the top main shaft extension section. The large torque is smoothly transmitted from the connecting seat 730 to the annular connecting piece 720520 on the outer ring. The scraper strips the gelatinous sludge adhering to the wall at a specific angle. As the sludge rotates with the scraper, it is forced to slide down the slope of the funnel and towards the center due to the obstruction of the scraper's inclined surface. In this continuous process, the sludge is constantly turned over and squeezed, and the free water inside is pushed upward. Finally, only the highly concentrated viscous sludge successfully reaches the sludge outlet pipe 230 at the lowest point.

[0032] Furthermore, the water supply component 600 can regulate the liquid entering the sealed chamber. It is equipped with a solenoid valve to switch between different water inlet ports 620. One of the water inlet pipes is connected to the sealed chamber. When the probe inside the sealed chamber detects that the circulating water level is high and the pH value is within the normal range, a large amount of unreacted liquid in the upper part of the funnel section is pumped back into the centrifuge cup 400 to form an internal self-circulation effect. If the water level drops to a low level due to evaporation and consumption, or if the water quality drops to the threshold after being detected by the probe, new deodorizing liquid will be added from the other inlet 620 pipe to achieve a dynamic balance between economy and deodorizing efficiency.

[0033] Specifically, the atomized liquid that has completed the first round of hydrogen sulfide absorption and degradation at the bottom of the equipment accumulates to form a liquid pool; heavy metals, silt and other particles with a high specific gravity settle to the bottom and are slowly processed by the scraper; due to the absence of strong upflow interference, a relatively clear and transparent water layer is formed in the upper layer, that is, above the scraper assembly 700.

[0034] The PLC control system commands the water pump 630 to start, generating negative pressure to draw the clear liquid in the collection area out through the suction pipe. After passing through the coarse filter to intercept any occasional floating matter, the liquid is pressurized and sent into the top cover of the equipment through the first water inlet 620, and then re-injected into the center of the high-speed rotating centrifugal cup 400, starting a new round of centrifugal tearing and gas-liquid mass transfer cycle.

[0035] After several hours of continuous circulation, when the chemical sensors (such as pH meters) connected in series in the pipeline detect that the solution is acidic and has failed, or when the radar level gauge detects that the liquid in the chamber has fallen below the safety threshold due to evaporation with the exhaust gas, the controller immediately shuts off or proportionally reduces the circulation pump valve, while simultaneously opening the second inlet valve 620 connected to the external water source tank. The concentrated fresh deodorizing solution in the storage tank is injected into the pipeline network under pulsed pressure from the diaphragm pump, mixes with the residual circulating water, and then re-enters the atomization system.

[0036] Furthermore, when the top of the rotating rod 100 is connected to the rotating motor 800, the aforementioned pneumatic structure is mainly used as an auxiliary rotating component, and the rotating motor 800 can be used as the main transmission component. The pneumatic structure assists in driving the rotating rod 100 at the bottom, which can reduce the torque required to load the overall shaft material itself; or, combined with the aforementioned pneumatic structure, a frequency conversion state control can be formed, allowing the operator to steplessly adjust the rotational angular velocity of the centrifugal cup 400 online based on real-time monitoring data of the inlet odor concentration.

[0037] Furthermore, a baffle plate 210 is provided at the top of the sealed chamber. The baffle plate 210 is a gas-liquid separator, which allows the gas passing through the baffle plate 210 to be discharged from the gas outlet pipe 220, while the liquid is retained inside the overall equipment. The mud outlet pipe 230 can be equipped with a powerful suction and discharge pipe of a single screw pump, or a gravity mud discharge pipe equipped with a pneumatic knife gate valve, which together with the mud-liquid mixture inside is discharged to the outside of the equipment.

[0038] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
