Description

Technical Field

[0001] This invention belongs to the field of aquaculture water treatment and environmental protection technology, specifically relating to an integrated ultrasonic resonant cavity vortex defoaming and degassing device and process. Background Technology

[0002] In modern high-density aquaculture, with the increase in feed intake, dissolved organic matter (proteins, polysaccharides, etc.) accumulates in the water, easily generating large amounts of viscous foam under water flow agitation. Simultaneously, carbon dioxide accumulation and nitrogen supersaturation often occur in the circulating water, affecting not only water quality indicators but also potentially leading to gas bubble disease in fish. Existing treatment equipment typically employs either a single-tube cyclone or a simple multi-tube parallel connection. The former has a small treatment capacity, while the latter faces the problem of uneven water distribution—that is, the external annular inlet causes pressure differences in each branch pipe, affecting separation efficiency. Furthermore, traditional ultrasonic defoaming equipment often directly adheres the transducers to the curved cyclone tube wall. This contact installation is not only prone to detachment but also requires a large number of transducers in multi-tube systems, resulting in high costs and difficult maintenance. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an integrated ultrasonic resonant cavity vortex defoaming and degassing device and process, so as to at least solve some of the above-mentioned technical problems.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] An integrated ultrasonic resonant cavity cyclone defoaming and degassing device includes a central guide distribution component for receiving and diverting the liquid to be treated, a multi-tube cyclone component connected to the central guide distribution component, a negative pressure defoaming and degassing component connected to the multi-tube cyclone component, and a treatment liquid collection and drainage component connected to the multi-tube cyclone component; the multi-tube cyclone component is provided with an ultrasonic resonant coupling component, which includes an ultrasonic resonant coupling sealed box disposed on the multi-tube cyclone component and containing an ultrasonic coupling medium, and an ultrasonic transducer disposed on the ultrasonic resonant coupling sealed box, wherein the ultrasonic coupling medium is in full contact with the multi-tube cyclone component.

[0007] Furthermore, the cyclone tube is installed on the ultrasonic resonance coupling sealed box, and the middle section of the cyclone tube is located inside the ultrasonic resonance coupling sealed box, with the outer wall of the middle section of the cyclone tube in full contact with the ultrasonic coupling medium.

[0008] Furthermore, the negative pressure defoaming and degassing assembly includes an exhaust collection ring box connected to the cyclone tube. The exhaust collection ring box is equipped with a vacuum pump interface, and the exhaust collection ring box is connected to an external vacuum pump through the vacuum pump interface.

[0009] Furthermore, the top of the swirling tube is provided with an overflow pipe connected to the exhaust collection ring box, and the swirling tube is connected to the exhaust collection ring box through the overflow pipe.

[0010] Furthermore, the central flow distribution assembly includes a central conical distribution box, on which three flow dividers are connected, each flow divider connected to one of the aforementioned vortex tubes.

[0011] Furthermore, the treatment liquid collection and discharge assembly includes a treatment liquid collection tank, the bottom of the cyclone tube is connected to the treatment liquid collection tank, the treatment liquid collection tank is provided with a main drain port for discharging the treatment liquid, and the top of the central cone-shaped distribution box is provided with a main inlet port for the liquid to be treated.

[0012] Furthermore, the diverter is connected to the lower side wall of the central conical distribution box, and the diverter is tangentially and smoothly connected to the upper side wall of the vortex tube.

[0013] Furthermore, the three diverter tubes are at a 120-degree angle to each other, and the three vortex tubes are distributed in a circle around the central conical distribution box; there is a pair of ultrasonic transducers, which are symmetrically installed on the side walls at both ends of the ultrasonic resonant coupling sealed box.

[0014] An integrated ultrasonic resonant cavity cyclone defoaming and degassing device describes a defoaming and degassing process. The liquid to be treated enters from the central guide distribution component and, after buffering and pressure balancing within the component, is simultaneously and uniformly injected tangentially into the multi-tube cyclone component in a radial pattern. The liquid to be treated rotates at high speed within the multi-tube cyclone component, generating a centrifugal separation field. Simultaneously, an ultrasonic transducer generates ultrasonic waves that are transmitted to the multi-tube cyclone component through an ultrasonic coupling medium to destroy the foam structure within the liquid to be treated at room temperature and kill pathogens. Harmful gases released within the multi-tube cyclone component and broken foam residues are extracted through a negative pressure defoaming and degassing component. The liquid, after defoaming, degassing, and preliminary solid-liquid separation, enters the treated liquid collection and discharge component and is then discharged.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention features a simple structure and ease of use. Aquaculture wastewater is injected into a central conical distribution box from the top through a main inlet. After flow stabilization and buffering, it is evenly distributed to each cyclone tube via radially distributed branch pipes.

[0070] Example 10

[0071] like Figures 1-3 As shown, the present invention provides a defoaming and degassing process for an integrated ultrasonic resonant cavity cyclone defoaming and degassing device. The integrated ultrasonic resonant cavity cyclone defoaming and degassing device includes a central guide distribution component for receiving and diverting the liquid to be treated, a multi-tube cyclone component connected to the central guide distribution component, a negative pressure defoaming and degassing component connected to the multi-tube cyclone component, and a treatment liquid collection and drainage component connected to the multi-tube cyclone component.

The ultrasonic coupling medium is in full contact with the multi-tube cyclone component.

[0072] The defoaming and degassing process is as follows: the liquid to be treated enters from the central flow distribution component and, after buffering and pressure balancing within the central flow distribution component, is radially and uniformly injected tangentially into the multi-tube cyclone component. The liquid to be treated rotates at high speed within the multi-tube cyclone component, generating a centrifugal separation field. Simultaneously, the ultrasonic transducer generates ultrasonic waves that are transmitted to the multi-tube cyclone component through the ultrasonic coupling medium to destroy the foam structure within the liquid to be treated at room temperature and kill pathogens within it. The harmful gases released within the multi-tube cyclone component and the broken foam residue are drawn out through the negative pressure defoaming and degassing component. The liquid that has undergone defoaming, degassing, and preliminary solid-liquid separation enters the treated liquid collection and discharge component and is then discharged.

Its structure is compact and requires no heating, with ideal defoaming and degassing effects.

[0074] This invention relates to an integrated ultrasonic resonant cavity cyclone defoaming and degassing device and process. First, the aquaculture water to be treated is vertically injected into a central conical distribution box at the top of the device. After buffering and pressure balancing within the central conical distribution box, the fluid is simultaneously and uniformly injected tangentially into several surrounding cyclone tubes through radially distributed distribution pipes. Subsequently, the liquid rotates at high speed within the cyclone tubes, generating a centrifugal separation field. Simultaneously, the ultrasonic transducer on the ultrasonic resonant coupling sealed box surrounding the cyclone tubes is activated, transmitting ultrasonic waves through the cavity medium to the inside of the cyclone tubes, thereby destroying the foam structure and inactivating pathogens in the water at room temperature. Next, utilizing the low-pressure zone at the center of the cyclone, and in conjunction with an external vacuum system connected to the top, the released harmful gases and broken foam residue are drawn upwards. Finally, the water, having undergone defoaming, degassing, and preliminary solid-liquid separation, is discharged from the bottom outlet of the cyclone tubes.

[0075] The present invention has an ultrasonic resonant coupling cavity filled with an ultrasonic coupling medium, in which ultrasonic waves form a reverberant sound field, providing full coverage of all swirling tubes immersed in the cavity.

[0076] The central flow distribution component of this invention is located at the center of the top layer of the device and is used to receive and distribute the incoming water; the multi-tube vortex component includes several vortex tubes arranged in a circumferential array, and its tangential inlet is connected to the central flow distribution component; the ultrasonic resonance coupling component is a sealed box installed in the middle of the vortex tubes and covering them; the negative pressure defoaming and degassing component is connected to the top overflow port of each vortex tube; and the treated liquid collection and drainage component is connected to the bottom flow port of each vortex tube.

[0077] The central flow distribution assembly of the present invention includes an inverted conical or cylindrical central conical distribution box with a main inlet at the top and a branch pipe extending from the lower side corresponding to the number of swirling tubes. The branch pipe is smoothly connected to the tangential inlet of the swirling tube.

[0078] The ultrasonic resonant coupling assembly of the present invention includes a rectangular or polygonal resonant chamber and several sets of ultrasonic transducers mounted on the outer wall of the chamber; the column section of the cyclone tube passes through the resonant chamber, and the space between the outer wall of the cyclone tube and the resonant chamber is filled with an ultrasonic coupling medium.

[0079] The overflow pipe at the top of the cyclone tube of this invention serves as a channel for the discharge of gas and foam. After being connected to the gas-liquid separator or vacuum pump through pipelines, it is not used for discharging treated water.

[0080] The treatment liquid collection and discharge assembly of the present invention is a sludge collection chamber, and the underflow ports of all cyclone tubes extend into the sludge collection chamber. The sludge collection chamber is provided with a main drain port on the side or bottom.

[0081] The ultrasonic transducers of this invention are symmetrically mounted on opposite side walls of an ultrasonic resonant coupling sealed box to form a stable standing wave field inside the box.

[0082] All components of this invention that come into contact with liquids are made of corrosion-resistant engineering plastics or stainless steel, making them suitable for seawater or freshwater aquaculture environments.

[0083] In practical applications, this invention effectively solves the technical problem of uneven hydraulic distribution in multi-tube systems by utilizing a central liquid inlet distribution system. Furthermore, the resonant cavity effectively achieves efficient physical defoaming and degassing. Its compact structure requires no heating, and its defoaming and degassing effects are ideal in practical applications. This is mainly demonstrated in the following scenarios.

[0084] Practical Application Scenario 1: Standardized defoaming and deaeration in a factory-scale recirculating aquaculture system. In a large-scale grouper recirculating aquaculture plant, this device is used before the biological filtration unit to remove protein foam from the water and prevent bubble disease. The device adopts a three-pipe parallel structure with a central 5 L conical distribution chamber. The aquaculture return water is injected into the distribution chamber from the top through the main inlet, and after buffering, it is evenly injected into three 75 mm diameter cyclone tubes through three branch pipes at 120-degree angles to each other. The middle of the cyclone tube is enclosed in a water-filled square stainless steel resonant box, with two 50 W / 28 kHz transducers installed on each side wall of the box. When the water flows inside the tube at a speed of 1800 rpm, the ultrasonic waves in the resonant box penetrate the tube wall, instantly shattering the organic foam in the water. Simultaneously, a vacuum pump connected to the top interface of the cyclone tube continuously extracts the released carbon dioxide and the broken foam residue at a negative pressure of -0.02 MPa. The treated water, carrying a small amount of solids, settles into the bottom collection chamber and is discharged through the main drain outlet into the microfiltration unit. Operational results show that this device effectively controls foam buildup in the workshop, reducing total gas saturation by more than 15%.

[0085] Practical Application Scenario 2: High-viscosity foam treatment in high-density shrimp farming wastewater. Addressing the characteristics of high-viscosity foam, even mousse-like accumulation, in shrimp farming wastewater, the device was specifically adjusted. The transducer within the ultrasonic resonant coupling cavity was set to a dual-frequency alternating operating mode (20 kHz / 40 kHz). The low-frequency waves, with their large amplitude, physically tear apart the stubborn viscous foam film, while the high-frequency waves emulsify microbubbles. To prevent blockage by a large amount of suspended solids in the wastewater, the inlet diameter of the central conical distribution cavity was enlarged, and a pre-filter was added. During the treatment process, the high-intensity ultrasonic cavitation not only effectively breaks down the foam but also physically kills pathogenic Vibrio bacteria in the wastewater using the cavitation jet. Actual monitoring shows that, without adding any chemical defoamers, the visible foam removal rate in the wastewater can reach over 90%, and the number of Vibrio bacteria in the effluent can be effectively reduced by approximately 80%, significantly alleviating the environmental pressure of wastewater discharge.

[0086] Practical Application Scenario 3: Precision microbubble removal in fish fry breeding workshops. During the fry growth stage, tiny bubbles adhering to the fry's surface or being ingested can lead to severe mortality. This embodiment effectively demonstrates the application of the device of this invention in precision degassing. The device's central distribution design ensures extremely low hydraulic shear fluctuations, protecting fragile fry (if applied to the main circulating water system) or ensuring extremely stable water quality. At this time, the top vacuum interface connects to a high-precision negative pressure control system, maintaining a stable negative pressure of -0.05 MPa. The ultrasonic power is adjusted to a low level, mainly utilizing the standing wave field of the resonant cavity to cause micron-sized bubbles in the water to coalesce into larger bubbles, which are then rapidly drawn away by the negative pressure air column at the center of the vortex. Unlike the previous two cases, which focused on defoaming and sludge removal, this case focuses on "deep degassing." Continuous operation data shows that the dissolved oxygen content of the treated water remains within a safe range, while the nitrogen supersaturation rapidly drops from 110% to below 98%, completely eliminating the pathogenic factors of gas bubble disease.
