A specific structure of the microbubble generation circulation system 1 according to the embodiment of the present invention is described below with reference to fig. 1 to 4.
As shown in fig. 1, a microbubble generation circulation system 1 according to an embodiment of the present invention is used to continuously add microbubbles to a water intake 70, and the microbubble generation circulation system 1 includes a dissolved air tank 10, a water pump 20, a water valve 30, a gas valve 40, and a cavitation member 50. A dissolved air tank 10 is provided for dissolving air in a flow of water, the dissolved air tank 10 having an inlet 110 and an outlet 120, the outlet 120 being adapted to be connected to a water intake 70. The water pump 20 is used to drive water taken from the water intake 70 towards the dissolved air tank 10. The water valve 30 is adapted to be positioned between the water pump 20 and the point of extraction 70 to control the flow of water to the water pump 20, and the air valve 40 is positioned between the water valve 30 and the water pump 20 to control the flow of air to the water pump 20. The cavitation member 50 is adapted to be connected between the gas dissolving tank 10 and the water intake 70, and the cavitation member 50 bubbles the gas dissolved therein by a cavitation effect.
It will be appreciated that the water pump 20 is operated to draw water from the water intake 70 through the water valve 30, and that the water pump 20 is operated with the water supply pressurized, such that the water pressure at the water outlet of the water pump 20 is higher than the water pressure at the water inlet of the water pump 20, and the pressurized water is injected into the dissolved air tank 10 through the water pipe. The water amount in the dissolved air tank 10 is gradually enriched until the pressure of the residual gas is equal to the water pressure of the water injected by the high-pressure water pump 20, so that the pressurization of the gas in the dissolved air tank 10 is realized. Since the solubility of air is higher in the high pressure state than in the low pressure state, this process increases the solubility of air in water, and the air in the dissolved air tank 10 is sufficiently dissolved into water. The outlet 120 of the dissolved air tank 10 is connected to the cavitation member 50, and by the cavitation effect, a large amount of air dissolved in water is cavitated and separated in the form of micro bubbles, thereby generating micro bubble water. In the process, the water pump 20 has a supercharging effect, the water outlet pressure of the water pump 20 is far greater than the tap water pressure, more air can be dissolved in water, and more micro bubbles can be generated during precipitation through cavitation. Because the cavitation member 50 is connected to the water intake 70, micro-bubble water will enter the water intake 70. In summary, the water in the water intake 70 flows through the dissolved air tank 10 and the cavitation member 50 in sequence by the driving of the water pump 20, and finally forms micro bubble water containing bubbles to return to the water intake 70, that is, the micro bubble water with bubbles is circulated and continuously introduced into the water intake 70. In addition, the microbubble generation circulation system 1 according to the embodiment of the present invention has a simple structure, and before the cavitation member 50 performs cavitation on the water flow, the water flow will fully dissolve air while flowing through the air dissolving tank 10, thereby increasing the number of bubbles generated by the cavitation.
It should be noted that, when the microbubble circulation system operates for a long time, the air in the air dissolving tank 10 gradually decreases, which affects the number of bubbles generated by the cavitation element 50. Therefore, after the micro-bubble generation circulation system 1 works for a period of time, the air valve 40 connected with the water pump 20 is opened, so that air can enter the dissolved air tank 10, and the bubble generation amount is ensured.
According to the micro-bubble generation circulation system 1 of the embodiment of the present invention, since the water in the water intake 70 sequentially flows through the dissolved air tank 10 and the cavitation member 50 by the driving of the water pump 20, and finally forms micro-bubble water containing bubbles to return to the water intake 70, the micro-bubble generation circulation system 1 can efficiently and continuously generate the micro-bubble water in a circulating manner. Meanwhile, the microbubble generation circulation system 1 according to the embodiment of the present invention has a simple structure, and before the cavitation member 50 performs cavitation on the water flow, the water flow will fully dissolve air while flowing through the air dissolving tank 10, thereby increasing the number of bubbles generated by the cavitation. In addition, the microbubble generation circulation system 1 of the embodiment of the present invention also has the gas valve 40 for supplying gas, thereby achieving efficient and stable generation of microbubbles for a long time.
It should be additionally noted that the cavitation member 50 may be provided in various forms, for example, as shown in fig. 2-3, in some embodiments of the present invention, the cavitation member 50 is provided at the outlet 120 of the cylinder 10. For example, as shown in fig. 4-5, in other embodiments of the present invention, the cavitation member 50 is disposed outside the dissolved air tank 10, and has one end connected to the dissolved air tank 10 and the other end connected to the water intake 70. For another example, in some embodiments of the present invention, cavitation member 50 is formed directly at outlet 120 of cylinder 10.
In some embodiments, during the operation of the microbubble generation circulation system 1, the water pump 20 is continuously operated, and the water valve 30 and the gas valve 40 are intermittently conducted. It is understood that when the microbubble generation circulation system 1 starts to operate, the water valve 30 is in an open state, the gas valve 40 is in a closed state, and the gas valve 40 is airtight, at this time, the water at the water intake 70 flows through the dissolved air tank 10 and the cavitation member 50 in sequence by the driving of the water pump 20, and finally the microbubble water formed with bubbles returns to the water intake 70. After the water-soluble air tank 10 runs for a certain time, the air in the water-soluble air tank 10 is depleted along with water, at this time, if the water pump 20 continuously pumps water again, the effect of generating micro bubbles is poor, at this time, the water valve 30 is closed, the air valve 40 is opened, the water pump 20 continuously runs pumps air from the air through the air valve 40, the air is conveyed into the water-soluble air tank 10, the water in the water-soluble air tank 10 is discharged, and the air is filled again. When the air dissolving tank 10 is filled with air, the air valve 40 is closed, the water valve 30 is opened, and a new microbubble cycle is continued. In summary, the continuous generation of the micro bubbles in the water intake 70 is realized by the alternate opening and closing of the water valve 30 and the air valve 40.
In some embodiments, the outflow rate of cavitation member 50 is less than the inflow rate of dissolved air tank 10. The flow rate at the inlet 110 of the dissolved air tank 10 is always greater than the flow rate at the outlet of the cavitation member 50. It should be noted that, because the inlet 110 flow rate of the dissolved air tank 10 is always greater than the outlet flow rate of the cavitation member 50, the water level will gradually increase when water is injected into the dissolved air tank 10, and the dissolved air tank 10 is a relatively closed space, the rising of the water level will gradually increase the air pressure inside the dissolved air tank 10, the solubility of the air in the high-pressure state is greater than that in the low-pressure state, that is, more air can be dissolved in the water at this time, the air content in the water flow passing through the dissolved air tank 10 is increased, so that the water flow can generate more bubbles when passing through the cavitation member 50.
In some embodiments, as shown in fig. 7, the cavitation member 50 includes a venturi 510. This makes it possible to relatively easily separate out the air dissolved in the water flow passing through the cavitation member 50 and to form bubbles. The venturi tube 510 is used as the cavitation member 50, and it is not necessary to design redundant water pumps, heating devices or control valves, etc., so that the structure of the cavitation member 50 is greatly simplified, the production cost is reduced, and the venturi tube 510 has no additional requirement for the water inlet manner, so that the cavitation member 50 can easily generate a large amount of bubbles.
Specifically, the minimum radius of the venturi tube 510 is 0.01mm-10mm, and the radii of both ends of the venturi tube 510 are greater than or equal to the minimum radius of the venturi tube 510. It should be noted that the tube diameter of the venturi tube 510 determines the degree of hydrodynamic cavitation, and experiments prove that the venturi tube 510 with the above parameters has better cavitation effect and can generate more bubbles. More advantageously, the venturi 510 has a bore diameter of 1.5 mm. Of course, the specific parameters of the venturi tube 510 can be adjusted by the operator according to the actual working conditions, and are not limited to the above range.
More specifically, the radii of both ends of the venturi tube 510 are each 0.001mm to 30mm larger than the smallest radius of the venturi tube 510. It can be understood that, the venturi tube 510 has a throat part with a narrowed end in the middle of the structure, and due to the narrowed radius, the flow velocity and the instantaneous water pressure of the water flow can both change in a sheet manner, so that the cavitation effect of the venturi tube 510 can be improved. Experiments prove that the venturi tube 510 with the above parameters has better cavitation effect and can generate more bubbles. More advantageously, the radii of both ends of the venturi 510 are each 1mm greater than the smallest radius of the venturi 510. Of course, the specific parameters of the venturi 510 can be adjusted by the operator according to the actual working conditions, and are not limited to the above range.
In some embodiments, the sum of the narrowest location areas of the venturi tubes 510 is, under any condition, less than the area of the inlet 110 of the dissolved air vessel 10. From this, can make the entry 110 flow that dissolves gas pitcher 10 be greater than venturi 510's exit flow all the time, consequently when dissolving gas pitcher 10 internal water injection, the water level can increase gradually, and dissolve gas pitcher 10 for relatively airtight space, the rising of water level can make the inside atmospheric pressure that dissolves gas pitcher 10 increase gradually, the solubility of air under high pressure state is greater than the low pressure state, that is to say this moment aquatic can dissolve more air, increased the air content in the rivers that pass through dissolve gas pitcher 10 from this, make rivers can produce more bubbles when passing through venturi 510 device.
In other embodiments, cavitation member 50 is an orifice plate having a plurality of micro-orifices. This makes it possible to easily separate out the air dissolved in the water flow passing through the cavitation member 50 and to form bubbles. The orifice plate with a plurality of micropores is used as the cavitation piece 50, redundant water pumps, heating devices or control valves and the like are not needed to be designed, the structure of the cavitation piece 50 is greatly simplified, the production cost is reduced, and the orifice plate has no additional requirement on a water inlet mode, so that the cavitation piece 50 can easily generate a large amount of bubbles.
Specifically, the radius of the micropores on the pore plate is 0.01mm-10 mm. Experiments prove that the orifice plate with the parameters has better cavitation effect and can generate more bubbles. Of course, the specific parameters of the orifice plate can be adjusted by the operator according to the actual working conditions, and are not limited to the above range.
In some embodiments, as shown in fig. 3 and 5, a water flow excitation plate 130 is disposed in the dissolved air tank 10 corresponding to the inlet 110. It can be understood that, when the inflow water flows through the water flow excitation plate 130, a large amount of water splash is splashed due to the blocking and diversion effects of the water flow excitation plate 130, so that the water flow can be sufficiently mixed with the air inside the dissolved air tank 10, the contact area between the water flow and the air is increased, and the dissolving speed of the air is accelerated.
In some embodiments, water flow activation plate 130 has a lowest point. Therefore, the water splash splashed by the water flow excitation plate 130 can be larger, and the contact area between the water flow and the air is further increased. Advantageously, the water flow activation plate 130 is formed in an arc shape, however, the water flow activation plate 130 may have a flat plate shape or the like.
In some embodiments, inlet 110 is provided at the top of dissolved air tank 10, and water flow excitation plate 130 is located below inlet 110. It should be noted that the inlet 110 is provided at the top of the dissolved air tank 10 so that the water flow can fall down by its own weight, and the water flow can be prevented from flowing out of the dissolved air tank 10 from the inlet 110.
Specifically, the lowest point of the water flow excitation plate 130 is provided with a through hole. Therefore, the water flow can be prevented from exciting the accumulated liquid on the plate 130, and the water resource is wasted.
Specifically, the distance between the lowest point of the water flow excitation plate 130 and the outlet 120 is equal to or greater than 0.05 mm. It can be understood that, since the water level inside the dissolved air tank 10 changes from moment to moment during the work of the dissolved air tank 10, the distance between the lowest point of the water flow excitation plate 130 and the outlet 120 is too small, which easily causes the water flow excitation plate 130 to obstruct the water flow from flowing out, and the water splash splashed by the water flow excitation plate 130 may directly splash at the outlet 120 and flow out of the dissolved air tank 10, thereby reducing the water treatment effect of the micro-bubble generator 1. Therefore, in order not to affect the water output of the outlet 120, the water flow excitation plate 130 needs to be at a distance of at least 0.05mm from the water outlet.
Optionally, the fall between the lowest point and the highest point of the water flow excitation plate 130 is greater than or equal to 0.05 mm. It should be noted that the difference between the highest point and the lowest point of the water flow exciting plate 130 is too small to play a good role in splashing water flow. Therefore, the fall between the lowest point and the highest point is greater than or equal to 0.05mm, so that the water splash splashed by the water flow excitation plate 130 is larger, and the contact area between the water flow and the air is further increased.
In some embodiments, the inlet 110 of the dissolved air tank 10 is formed in a shape large at the top and small at the bottom. Note that, the inlet 110 of the dissolved air tank 10 is formed in a shape having a large top and a small bottom, so that tap water is sprayed when entering the dissolved air tank 10 through the inlet 110. Therefore, the contact area of water flow and air can be increased, the dissolving speed of the air is accelerated, the water inlet pressure can be increased, tap water with higher pressure can dissolve more air, and the solubility of the air can be increased by increasing the water inlet pressure.
In some embodiments, the microbubble generation circulation system 1 further includes a pressure sensor for detecting the hydraulic pressure or the air pressure in the dissolved air tank 10, and the pressure sensor is electrically connected to the air valve 40. From this, pneumatic valve 40 can guarantee to have the air of capacity in dissolving gas pitcher 10 all the time according to the data switching that pressure sensor or level sensor detected, and then guaranteed that rivers can dissolve the air of capacity when dissolving gas pitcher 10 to guarantee that rivers can produce the microbubble of capacity when cavitation 50.
In some embodiments, as shown in fig. 6, cylinder 10 has a spout 140 extending from inlet 110, the spout of spout 140 extending into cylinder 10 forms a spout 141, and the flow area of spout 141 is smaller than the flow area of inlet 110. It is understood that the water taken from the water intake 70 is pressurized by the water pump 20, enters the water spray pipe 140 of the dissolved air tank 10, and is sprayed from the water spray port 141. Since the flow area of the water jet 141 is smaller than the flow area of the inlet 110, the water pressure of the water flow is increased when the water flow is ejected from the water jet 141, so that more air can be dissolved in the water flow, and the number of bubbles generated by the cavitation effect is increased.
Specifically, the water spray port 141 sprays water toward the top wall of the dissolved air tank 10, and the outlet 120 is provided on the bottom wall of the dissolved air tank 10. Accordingly, the water droplets are discharged from the water discharge port 141 and then gradually fall down by gravity, so that air can be sufficiently dissolved in the water droplets, and the amount of air dissolved in the water flow is increased, thereby increasing the number of bubbles generated by the cavitation effect.
