[0003] FIELD OF INVENTION

[0004] The present invention relates to the water or wastewater treatment industry, aeration, gas fixation in liquid fluids, the mining industry, agriculture, aquaculture, and / or gas dilution in liquid fluids. In particular, the present invention relates to a system that increases the percentage of gas dissolution in a liquid fluid and is optionally compact and mobile, thus achieving a high oxygen / air dissolution capacity in an aqueous fluid in a small / compact and / or transportable system with low energy consumption relative to the oxygen dissolution capacity (0.22 to 0.57 kWh / kgO2) and which does not require cranes or additional machinery for transport.Furthermore, this system incorporates turbulence-generating elements, or vanes, and achieves resonance of the gas bubbles within the liquid fluid. This further increases the percentage of gas dissolution in the liquid fluid with low energy consumption, where the bubble size is on the order of micro and nano bubbles. Another advantage of this system is that, with the configuration of an ultrasonic transmission medium and an ultrasonic transducer, the equipment is self-cleaning, thus reducing maintenance frequency and improving the system's operational continuity.

[0005] STATE OF THE ART

[0006] Currently, in the water and wastewater treatment industry, aeration, mining, agriculture, aquaculture, and / or gas dilution in liquid fluids, a common problem is that the equipment achieves low gas dilution in the liquid fluid and is often a large installation, typically embedded in buildings, sheds, and / or fixed structures, with high energy consumption relative to its oxygen dissolution capacity. Various solutions have been found in the state of the art, but these only partially and inefficiently address the technical problem.Among the known is publication number KR 20180096247 A, which discloses an oxygen dissolution apparatus for a water tank, installed, in pipe form, in a pipe connecting between a water pump and the water tank, on a ship, which includes: a plurality of water tanks filled with live fish; the water pump that pumps seawater to supply it to the water tanks; and the pipe that supplies the seawater pumped from the water pump to the water tanks, wherein the oxygen dissolution apparatus comprises: a dissolution tube coupled to the pipe; an oxygen injection unit that supplies oxygen upstream within the dissolution tube; and an ultrasonic apparatus disposed downstream of the oxygen supply aeration unit.The oxygen supply aeration unit delivers oxygen from an external oxygen source to the seawater flowing through the dissolution tube via an oxygen distribution nozzle installed in the dissolution tube. The ultrasonic oxygen apparatus comprises: an ultrasonic oscillation circuit; and an ultrasonic vibration unit that induces vibration in the seawater by means of ultrasonic waves oscillated by the ultrasonic oscillation circuit to cause resonance in the air molecules dissolved in the water by means of ultrasonic waves to improve the solubility of oxygen in water. However, this document does not disclose a system that increases the percentage of dissolution of a gas in a liquid fluid and that is optionally compact and portable.

[0007] Another document is publication number US20190374912A1, which discloses a method for manufacturing beverages or other liquids containing bubbles. This method uses a system for manufacturing liquids containing bubbles that includes: a bubble-generating unit that generates fine bubbles in a liquid; a bubble-collapse unit that is connected to the bubble-generating unit to collapse the fine bubbles contained in the bubble-containing liquid supplied from the bubble-generating unit by passing the bubble-containing liquid through the bubble-collapse unit and irradiating the bubble-containing liquid with an ultrasonic wave; and a storage unit that is connected to the bubble-collapse unit to store the bubble-containing liquid supplied from the bubble-collapse unit.The method includes: a bubble generation stage to generate fine bubbles in the liquid using the bubble generator unit; a bubble collapse stage to generate superfine bubbles by creating an ultrasonic field using the bubble collapse unit to collapse the fine bubbles contained in the liquid; and a storage stage to store the bubble-containing liquid containing the superfine bubbles using the storage unit. Consequently, a beverage or other liquid containing superfine bubbles can be manufactured. However, this document does not disclose a system that increases the percentage of dissolution of a gas in a liquid fluid and that is optionally compact and portable.

[0008] SOLUTION TO THE TECHNICAL PROBLEM

[0009] To address the problem, a system is presented that increases the dissolution rate of a gas in a liquid fluid. This system, which is compact and mobile, achieves a high oxygen / air dissolution capacity in an aqueous fluid within a small, compact, and energy-efficient system (0.22 to 0.57 kWh / kgO2) relative to its oxygen dissolution capacity. It does not require cranes or additional machinery for transport. Furthermore, the system incorporates gas injection mechanisms and turbulence-generating elements (vanes) to promote the mixing of gas bubbles in the liquid fluid. This further increases the gas dissolution rate, resulting in a gas dissolution capacity-to-volume ratio of 33 to 200 kg / h / m³. 3 .

[0010] Another additional feature of the present system is that with an ultrasonic transmission medium with an ultrasonic transducer that performs a dual function, promoting the dissolution of the gas in the liquid fluid, increasing the gas dissolution capacity in the system, and enabling the equipment to self-clean, thereby reducing the frequency of maintenance and increasing the operational continuity of the system.

[0011] Furthermore, this system is transportable either manually or because it has wheels and / or can be moved with manual equipment such as pallet jacks or loaded onto a light truck with the aid of a forklift. It is also understood that transportability or compactness means this system can be integrated or included in other means of transport such as boats, ships, and / or trucks. Moreover, it is applicable to systems that provide air, oxygen, and / or air or oxygen dissolved in water, in the form of containers, pontoons, and / or naval vessels. SUMMARY DESCRIPTION OF THE INVENTION

[0012] The present invention relates to a gas dissolution system in an aqueous medium that increases the percentage of dissolution of a gas in a liquid fluid, in the fixation of gases in liquid fluids, with low energy consumption in relation to an oxygen dissolution capacity (0.22 to 0.57 kWh / kgO2), water treatment, for aquaculture and / or the dilution of gases in liquid fluids, comprising: a chassis comprising a chamber containing pressurized aqueous fluid, wherein the chamber comprises: an inlet and an outlet of an aqueous fluid with at least one dissolved gas;to move the fluid from the proximal end to the distal end avoiding the use of external elements, such as auxiliary chambers and / or external pipes, improving the dilution of gases in an aqueous medium that increases the percentage of dissolution of a gas in a liquid fluid in a compact and / or transportable unit, a plurality of gas injection means located in said chamber; an ultrasonic transmission means located in the chamber and connected to an ultrasonic transducer and turbulence generation means located inside said chamber to maintain a turbulent regime and promote the mixing of the fluid with bubbles inside the chamber and thereby increase the amount of gas dissolved in the aqueous fluid, and optionally the system is small and lightweight, achieving a compact and manually transportable design.

[0013] Furthermore, the chassis comprises a pressurized aqueous fluid containment chamber, wherein the chamber comprises a proximal end with a fluid inlet operatively connected to at least one gas supply subsystem; and a distal end with an aqueous fluid outlet with at least one dissolved gas, operatively connected to at least one fluid distribution and injection subsystem, wherein the operative connections may be quick couplings, one-way valves, control valves, remotely controlled solenoid valves, ball valves or on / off valves, or a combination of these coupling means with valves.

[0014] Additionally, the application of ultrasound during system operation generates continuous cleaning of internal components such as filters, drums, vanes or turbulence generation means, ducts, inner chamber body, etc.), preventing the scaling or adhesion of solids, organic or inorganic material that may be present in the aqueous medium to the internal components, thus reducing the frequency of system maintenance.

[0015] The size of the bubbles generated is on the order of micro and nano bubbles; in particular, the bubbles have a size between 0.1 and 1000 micrometers.

[0016] In aquaculture, this system can be integrated into pressurized gas dissolution systems, where a flow of pressurized water is pumped and oxygen is injected, resulting in a mixture of water with dissolved or partially dissolved oxygen. This mixture is then distributed to the culture media or areas requiring supplemental oxygen. These systems are particularly useful when oxygen needs to be dissolved but there is insufficient water column height and / or when passive diffusion systems (bubble diffusion) are insufficient or inefficient to meet the oxygen demand of the medium. Some examples of scenarios where this occurs are:

[0017] 1. During chemical treatment of fish in sea cages, where the depth of the tanks is reduced to no more than 4 meters from the surface,

[0018] 2. For oxygenation in fish farms, where the depth of the culture ponds is 1 to 2 meters,

[0019] 3. For shrimp farming, where the depth of the farming ponds is 1 to 1.5 meters.

[0020] 4. In marine fish farms, where the biological oxygen demand is high and systems with high oxygen transfer efficiency are required. In this scenario, oxygen diffusion occurs at depths of 1 to 20 meters.

[0021] 5. For the treatment and recovery of the seabed underlying aquaculture centers through oxygenation, where oxygen is injected into a water flow directly into the marine sediment. There, it acts as a promoter of aerobic degradation reactions of the organic matter deposited as a result of aquaculture activities. In this scenario, the oxygen injection depth is greater than 20 meters and in some cases can be hundreds of meters, reaching the seabed.

[0022] For all the above scenarios, the compact shape and easy mobility of the system generate a technical advantage, as it can be used in confined spaces and relocated from one culture medium to another without the need for machinery or cranes.

[0023] Among the operational characteristics of the dissolution system, it is noteworthy that the residence time of the liquid and gaseous fluid mixture within the system is 10 to 15 seconds. During this time, the fluid mixture is subjected to pressures between 180 kPa and 320 kPa (1.8 and 3.2 bar), turbulence with Reynolds numbers between 50,000 and 200,000, and ultrasonic power between 4.5 and 5.5 kW per m³ 3 of liquid. In a preferred configuration, this system delivers a flow rate of between 50 and 60 m 3 / hour; at a pressure of approximately 2.5 bar, with a mass flow rate of between 15 kg / hour and 30 kg / hour of gas, with an energy consumption of between 7.5 and 8.5 kW, resulting in an energy consumption of between 0.25 and 0.57 kWh / kg O2(gas).

[0037] DETAILED DESCRIPTION OF THE INVENTION

[0038] As shown in Figures 1 to 5, a system (1) for dissolving gases in an aqueous medium is presented, which increases the percentage of dissolution of a gas in a liquid fluid in an economical, energy-efficient manner and through a compact and mobile configuration, for the treatment of water or wastewater, aeration, fixation of gases in liquid fluids in the mining, agricultural, and / or aquaculture industries, comprising: a chassis (200) comprising a chamber (100) containing pressurized aqueous fluid, wherein the chamber (100) comprises: a. a proximal end (100 p) with a fluid inlet (101);b. a distal end (100 d) with an outlet (102) for aqueous fluid with at least one dissolved gas, wherein the distal end (100 d) is operatively connected to at least one fluid distribution and injection subsystem (2000) for the fluid to move from the proximal end (100 p) to the distal end (100 d), avoiding the use of external elements such as auxiliary chambers and / or external piping, improving gas dilution in aqueous medium, which increases the percentage of gas dissolution in a liquid fluid in a compact and / or transportable unit; c. at least one gas injection means (103) disposed inside the chamber (100) and which may also be longitudinally oriented to the fluid, wherein the gas injection means (103) is operatively connected to at least one gaseous fluid supply subsystem (1000), wherein said chamber (100) further comprises;d. at least one ultrasonic transmission means (106) located in the central area of ​​the chamber (100) and in the longitudinal direction of the fluid, such that the gas (bubbles) injected by the gas injection means, also longitudinal to the fluid, is subjected to a constant ultrasonic power;and e. at least a pair of turbulence generating means (107) configured to generate dilution in a turbulent regime and promote mixing of the fluid and bubbles within the chamber (100), located inside said chamber (100) which includes at least a transverse component of the chamber (100) with respect to the direction of the fluid, wherein the first turbulence generating means is oriented opposite to the second turbulence generating means and the area of ​​each turbulence generating means comprises at least 20% of the transverse area of ​​the chamber (100) leaving at least one opening opposite the next opening, to maintain a turbulent regime and promote mixing of the fluid with bubbles within the chamber (100);wherein at least one ultrasonic transmission means (106) is operatively connected to at least one ultrasonic transducer (105), configured to increase the range of the ultrasonic waves and thereby increase the amount of gas dissolved in the aqueous fluid, thus improving dilution, and a drive and control unit (300) operatively connected to the at least one ultrasonic transducer (105), configured to control the ultrasonic frequency and deliver electrical power to the at least one ultrasonic transducer (105), transforming the electrical energy into mechanical vibration energy.

[0039] Thanks to the synergistic combination of the turbulence generation means (107) together with the ultrasonic transmission medium (106) and the ultrasonic transducer (105), very good results are obtained, such as the high residence time of the liquid and gaseous fluid mixture within the system, on the order of 10 to 15 seconds, with a turbulent regime, with turbulence with Reynolds numbers between 50,000 and 200,000 and with ultrasonic powers between 4.5 and 5.5 kW per m 3of liquid, which is a low energy consumption for the working flow rate of between 50 and 60 m3 / hour circulating through the system (1) of gas dissolution in aqueous medium, with a mass flow rate of between 15 kg / hour and 30 kg / hour of gas, with an energy consumption of between 7.5 and 8.5 kW. Resulting in an energy consumption per unit mass of between 0.25 and 0.57 kWh / kg O2 (gas). The above promotes the dilution of gaseous fluids in liquid fluids, since the combination of these three elements inside a pressurized chamber, i.e. the turbulence generation means (107), the ultrasonic transmission medium (106) and the ultrasonic transducer (105) described above, allows the production of bubbles of a size between 0.1 and 1000 micrometers inside said pressurized chamber, with pressures between 180 kPa and 320 kPa (1.8 and 3.2 bar).

[0087] APPLICATION EXAMPLES

[0088] The following are examples of applications of the present invention. These examples are provided for illustrative purposes only to facilitate a better understanding of the invention, but in no case should they be considered as limiting the scope of the protection sought. Furthermore, specifications of different technical features described in the examples may be combined with each other, or with other technical features previously described, without limiting the scope of the protection sought.

[0089] EXAMPLE 1.

[0090] The results of the gas dissolution system in aqueous medium are described below, showing good results in the percentages of dissolution of a gas in a liquid fluid and the system remained clean without showing scaling or dirt after use, which increases the percentage of dissolution of a gas in a liquid fluid.

[0091] In one test, it was found that at an ultrasonic frequency of 28.8 Hz + / - 0.5 kHz in water, the gas bubbles present fragment, thereby increasing the dissolution of the gas in the medium. These measurements also indicate an increase in the generation of gas nanobubbles when the medium is subjected to this frequency.

[0092] It was also found that the ultrasonic power required to completely fragment a bubble flow of 7.4 m 3 / h (10 kg / h) was on the order of 1 kW.

[0093] A camera inclined at 3° to the horizontal was used, along with the dissolution system, which included an integrated water pump connected to a hydraulic circuit, to measure the oxygen transfer rate in a water flow. The hydraulic circuit allowed for the recirculation of a total volume of 4.4 m³. 3 of water, which implied a flow rate of 20 m 3 / h in recirculation. The dissolved oxygen concentration in the water was measured with an optical sensor prior to system activation, yielding a result of approximately 11.3 mg / L, representing an oxygen saturation of 98%. A pressurized oxygen tank was used as the oxygen source. The dissolution system was activated, generating a water flow that maintained a flow rate between 22 and 24 m³ / h in recirculation. 3 / h, an oxygen flow that was set to 7.4 m 3The system delivered 10 kg / h of oxygen and consumed a total measured energy of 5 kW from the grid, resulting in a gas-to-liquid volumetric flow ratio of 0.28 to 0.34 and specific energy consumptions of 0.5 kWh per kilogram of injected oxygen (0.5 kWh / kgO2). The pressure within the dissolution system was maintained between 240 kPa and 270 kPa (2.4 and 2.7 bar). After approximately 3.5 minutes of system operation, it reached an oxygen concentration in the water of 44 mg / L and an oxygen saturation of 380%. The system used in this example was small and compact, measuring 1.3 meters long, 0.56 meters wide, and 1.1 meters high, and lightweight, weighing 142 kg empty.

[0094] After approximately 12.5 minutes of system operation, the oxygen concentration in the water reached 49 mg / L, with an oxygen saturation of 427%. This increase in oxygen levels is shown graphically in Figure 2. During system operation, water samples were taken for visual analysis, revealing a turbid appearance characteristic of the presence of micro- and nano-bubbles of oxygen. These samples were then subjected to laboratory analysis using the NANOSIGHT instrument (sCMOS camera, Blue488 laser) to quantify the nano-bubble content. This analysis yielded an average concentration of 769 million nano-bubbles per milliliter, with an average size of 120 nanometers and a mode of 74 nanometers. The nano-bubble size distribution obtained from this analysis is shown in Figure 3.This operational system allowed for the quantification of oxygen transfer rates in water and the validation of micro- and nano-bubble generation. This was achieved through the combination of physical effects such as pressure, turbulence (due to factors including the presence of turbulence-generating media), and the fragmentation of gas bubbles in water using ultrasound. As this example demonstrates, a synergistic effect was observed between gas diffusion in the aqueous medium, turbulence generation, pressurization of the medium, and the implementation of ultrasound. This synergy resulted in increased oxygen dissolution capacity in water within a compact system.

[0095] EXAMPLE 2.

[0096] A chamber inclined at 6° to the horizontal was used, along with the dissolution system and an integrated water pump, to oxygenate seawater within an industrial shipyard. Seawater was drawn in at a depth of 1 meter and released at a depth of 3 meters (both measurements taken from sea level). Through a horizontal manifold with multiple outlets, a homogeneous mixture of seawater and oxygen at a concentration of 44 mg / L and a saturation of 383% was discharged. The injected oxygenated mixture contained bubbles smaller than 1 millimeter, most of which dissolved as they traveled through the water column. A pressure inversion adsorption (PSA) oxygen generator was used as the oxygen source. During the approximately 2-hour operation, the water flow rate was maintained between 49 and 55 m³ / s. 3 / h, the oxygen flow was regulated between 14.8 and 18.5 m3 The flow rate was 20 to 25 kg / h, and the internal pressure of the dissolution system fluctuated between 230 kPa and 250 kPa (2.3 to 2.5 bar). The volumetric flow ratio between the gas and the resulting liquid ranged from 0.26 to 0.38. The average electrical consumption was 7.5 kW, resulting in specific consumptions ranging from 0.3 to 0.38 kW per kilogram of injected oxygen (0.28 to 0.3 kWh / kgO2). These tests were performed in a dissolution system comprising a cylinder with an internal volume of 0.2 m³. 3The device features an internal structure comprising an ultrasonic drive rod centered on the cylinder axis, five sintered gas injection filters parallel and equidistant from the ultrasonic drive rod, and four semicircular turbulence generators equidistant from each other and oriented vertically to the ultrasonic drive rod. This design includes an integrated pump for liquid propulsion and wheels for transport. Its approximate weight is 120 kg without liquid. The design incorporates stainless steel and high-density plastic components. It also includes a control panel with power switches for the water pump and ultrasonic generator, and a rotameter for gas flow regulation.

[0097] The use of this system under the specified operating conditions validated its application in marine aquaculture, achieving low specific consumption rates when injecting water and oxygen mixtures at depths greater than 1 meter but less than 4 meters. These depths are common, for example, during antiparasitic chemical treatments in fish farming cages, particularly for salmonids, which require supplemental oxygen injection systems suitable for oxygen injection at depths less than 4 meters.

[0098] Furthermore, comparative tests were conducted on a hydraulic bench to calculate the oxygen transfer rate in water, using various gas dissolution mechanisms, such as oxygenation cones, Venturi injectors, static mixers, ultrasound, combinations thereof, and the developed dissolution system. These tests showed that the oxygen transfer rate in water is up to 280% higher when using the present system compared to other conventional dissolution mechanisms. The oxygen increase curves from these comparative tests are presented in Figure 4.
