Description

Device for generating fine bubbles

Technical Field

The utility model relates to a micro-bubble takes place technical field, especially relates to a device for producing micro-bubble.

Background

People found micro-nano bubbles as early as 60 years and applied to the contrast technology. After 2000 years, more characteristics and applications of micro-nano bubbles are researched, and the micro-nano bubbles are found to have the characteristics of extremely slow rising speed in water, self-pressurization dissolution, extremely high mass transfer efficiency (more than 95%) and the like, and also have the characteristics of capability of greatly improving the solubility of gas, large surface specific contact area, high interface potential, excellent air flotation effect, reduction of liquid flow resistance, interruption of chemical bonds of surrounding water molecules by explosion in the micro-field of bubbles to generate free radicals and the like.

For aquaculture, the fish culture density can be improved by more than two times, the culture period is greatly shortened, the feed conversion rate is improved, the air floatation characteristic can float floccule air in fish dung and residual fish feed melting water to the water surface, the ammonia nitrogen and nitrite indexes in water are greatly reduced, zero-antibiotic and zero-tail-water culture is realized, the yield can be increased, and the method has great significance for food safety and environmental management of fish.

For crop planting, the micro-nano bubbles can increase the yield of rice planting by more than 50%, so that the root system of rice is developed, and the lodging resistance of rice is greatly improved. The micro-nano bubble water is used for planting crops, so that the yield is increased, and the soil environment can be improved and treated.

For improving the water body, the high dissolved oxygen value is the key of water treatment, the root cause of the black and odorous water body is oxygen deficiency, oxygen is supplemented, the ecological chain can be recovered by self, and the water body is treated.

In addition, the micro-nano bubbles can also reduce the sliding resistance of the liquid, and the effect of accelerating the ship is achieved.

The micro-nano bubbles are not only limited to air and oxygen, but also can be gases such as carbon dioxide, ozone and the like, and the ozone water body with high concentration and high contact area is an advanced oxidation technology in the industry, has remarkable application significance, and not only is the ozone water body applied to the industry, but also can play an important role in disinfection and sterilization of food. In addition, the high-concentration carbon dioxide water body can assist the industrialization of microalgae oil preparation. The micro-nano bubble technology is an efficient gas-liquid mixing technology, breaks the conventional problem that nonpolar gas is difficult to dissolve in water, is a basic process, can permeate into various fields like electricity, and brings technical breakthrough.

The micro-nano bubbles have such an important function, but are not popularized and applied in a large scale in the actual production, only the research of a retention application experiment is carried out, and the core problems are that the energy consumption of the micro-nano bubble generator is extremely high, and the yield is increased without increasing income. However, the problem of energy consumption of various generators has not been broken through so far, most micro-nano bubble generators utilize high-speed water flow generated by a water pump to cut gas, the existing design idea is only limited to how to recycle the high-speed water flow, and the purpose of greatly reducing the energy consumption cannot be achieved substantially.

At present, there are various methods for generating micro bubbles, such as an ultrasonic method, a pressure and pressure release dissolved air method, a venturi jet method, a rotary cutting method, and the like, but due to the limited amount of bubbles generated by the ultrasonic method, the complicated equipment structure and the difficult implementation of the pressure and pressure release dissolved air method, the currently commonly used methods for generating micro bubbles are the venturi jet method and the rotary cutting method. The principle of the rotary cutting method is substantially the same as that of the pressurizing and pressure releasing method, pressure is released at an outlet through high-speed rotating liquid pressurizing and gas dissolving to generate micro bubbles, the rotary cutting method reduces the implementation difficulty and omits complicated pressurizing equipment compared with the pressurizing and pressure releasing method, water flow flows forwards in a rotating mode compared with a Venturi jet flow method, the water-gas fusion process is longer, and the particle size of bubbles formed at the outlet is finer. But large water pumps or dissolved air pumps (the lift is required to reach 20m to 40m, and the water pressure is 0.2MPa to 0.5MPa) are required to be used at the front ends of the Venturi jet method and the rotary cutting method, and the two methods cannot generate micro bubbles under the conditions of low speed and low pressure; limited by the water pump itself, water-to-air ratio cannot exceed 10: 1 (i.e. 1 volume of micro-fine bubbles is generated, 10 volumes of high-speed water flow is needed); in addition, the venturi tube and the rotary cutter which generate the micro-bubbles accelerate water flow by contracting the pipe diameter, and finally perform high-speed jet flow from the outlet, so that the energy consumption for generating the micro-bubbles by the venturi tube and the rotary cutter is huge, and the heat generation caused by the rotary friction of water in the extrusion process is also an important factor of high energy consumption. When the Venturi jet method and the rotary cutting method are adopted, a large-sized vehicle (such as a forklift or a crane) is needed to transport the large-sized water pump or the dissolved air pump, the construction difficulty is high, and the popularization and application of the micro-bubbles in the actual production are greatly restricted by the various problems.

Aiming at the problems that in the related art, the energy consumption for driving the water body to move is high, the investment cost is high and the generation effect of the micro bubbles is not good in the cutting process of the micro bubbles, an effective solution is not provided at present.

Therefore, the inventor provides a device for generating micro-bubbles by virtue of experience and practice of related industries for many years, so as to overcome the defects of the prior art.

Detailed Description

In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in fig. 1 to 4, the present invention provides a device for generating micro-bubbles, which comprises a generating chamber 1 and a pressure supply pipeline 3, wherein the pressure supply pipeline 3 is used for conveying gas into the generating chamber 1 to form a certain gas pressure in the generating chamber 1, the generating chamber 1 is arranged below the liquid level, at least a part of the contact surface between the generating chamber 1 and the liquid is provided with a micro-bubble generating layer 2, the generating chamber 1 is connected with one end of the pressure supply pipeline 3, the other end of the pressure supply pipeline 3 is positioned above the liquid level and is connected with a gas supply device, the gas in the generating chamber 1 passes through the micro-bubble generating layer 2 by increasing the gas pressure in the generating chamber 1 and forms micro-bubbles on the contact surface between the micro-bubble generating layer 2 and the liquid; the generating cavity 1 is driven to move in the liquid, and the gas in the generating cavity 1 is driven to synchronously move along with the generating cavity 1 so as to cut the micro-bubbles and enable the micro-bubbles to enter the liquid. Of course, the generation chamber 1 may be, but not limited to, rotating in the circumferential direction, and may also adopt various motion forms (e.g., swinging left and right, etc.), so as to meet the requirement of rapidly cutting the micro-bubbles on the liquid contact surface of the micro-bubble generation layer 2.

The utility model is provided with a micro-bubble generating layer 2 on at least part of the contact surface between the generating cavity 1 and the liquid, in the working process, the generating cavity 1 and the micro-bubble generating layer 2 are in a synchronous motion state, while the liquid is in a static state, thereby cutting the fine bubbles generated on the contact surface of the fine bubble generation layer 2 and the liquid to generate fine bubbles, because the micro-bubble generating layer 2 does not consume extra energy after obtaining the speed required by the movement, and the energy consumption required by the gas which continuously enters the micro-bubble generating material is extremely low when being driven, the utility model not only can achieve the purpose of generating micro-bubbles, and can effectively reduce production energy consumption, save production cost, can quickly generate a large amount of micro bubbles with uniform particle size, has great economic benefit, and is suitable for popularization and use. Although the motion through liquid can also cut out micro-nano bubble, adopt the motion of microbubble generation layer 2, and liquid is in quiescent condition, and its motion with the microbubble generation layer 2 outside can greatly reduce the energy consumption, if the motion through liquid cuts the micropore bubble that produces on the motionless microbubble generation layer 2, the liquid accelerates to the required power consumption of the same speed and is greater than the power consumption that microbubble generation layer 2 drove gas and accelerates to the same speed far away.

In the utility model, the thickness of the micro-bubble generation layer 2 ensures that the micro-bubble generation layer has enough strength to support the generation cavity 1 to move, and the thinner the micro-bubble generation layer 2, the smaller the air resistance, the better the gas penetrability of the micro-bubble generation layer 2; the size of the generation chamber 1 is not limited, and the larger the volume of the generation chamber 1, the larger the surface area of the fine bubble generation layer 2, and the larger the ventilation amount, but the larger the frictional resistance to be applied during the rotation.

Further, the pore diameter of the fine bubble generation layer 2 is less than 5 μm.

Further, the micro-bubble generating layer 2 is not limited to be made of a material with micro-pores, and may be a cathode or an anode for generating micro-bubbles on the surface of the material during the electrolysis.

Further, the air supply device may be, but not limited to, an air pump, and may supply air into the generation chamber 1 and form a certain pressure in the generation chamber 1.

Further, as shown in fig. 1 to 3, an air pump 4, a first filter 5 and a second filter 6 are sequentially arranged on the pressure supply pipe 3 along the flow direction of the air, the air pump 4, the first filter 5 and the second filter 6 are all positioned above the liquid level, and the pore diameter of the filter element on the second filter 6 is smaller than the pore diameter of the filter element on the first filter 5 and the pore diameter of the fine bubble generation layer 2. The dust in the gas is filtered by the first filter 5 and the second filter 6, wherein the first filter 5 is used for filtering the dust with large particle size in the gas, and the second filter 6 is used for filtering the dust with small particle size in the gas, so that the micro-bubble generation layer 2 is prevented from being blocked by the dust in a long-term working state, and the service life of the device is prolonged. In addition, the filter elements on the first filter 5 and the second filter 6 are all consumable products which are convenient to replace and can be replaced periodically. The gas in the generating cavity 1 can pass through the micro-bubble generating layer 2 through the centrifugal force generated by the rotation of the generating cavity 1 and form negative pressure in the generating cavity 1, so that the gas of the gas source enters the generating cavity 1 for supplement; however, the smaller the pores on the micro bubble generating layer 2, the larger the air resistance, and in the case that the centrifugal force generated by the rotation of the gas is not enough to pass through the micro bubble generating layer 2, the gas pump 4 can pump the gas into the generating chamber 1 to increase the gas pressure in the generating chamber 1, and further increase the penetrating power of the gas in the generating chamber 1, thereby ensuring the smooth passing of the gas through the micro bubble generating layer 2. Alternatively, the gas may be more easily penetrated by increasing the rotational speed of the generation chamber 1 and increasing the centrifugal force, but this method requires more energy consumption than the addition of the gas pump 4.

Further, as shown in fig. 1 to 3, a flow meter 7 is disposed on the pressure supply pipe 3 located upstream of the air pump 4, a pressure gauge 9 is disposed on the pressure supply pipe 3 located downstream of the second filter 6, and an adjusting knob 8 capable of controlling the flow rate of the air is disposed on the flow meter 7. The flow rate of the gas can be monitored in real time through the flowmeter 7, and the adjusting knob 8 on the flowmeter 7 is adjusted according to actual conditions, so that the flow rate of the gas in unit time is controlled, and the particle size of the micro bubbles is adjusted. Flow meter 7 may be, but is not limited to, a glass rotameter, among others.

In an optional embodiment of the present invention, as shown in fig. 1, the generation cavity 1 is a cylindrical structure enclosed by the micro-bubble generation layer 2 to form two end seals, the axial direction of the generation cavity 1 is set along the horizontal direction, the inner axis position of the generation cavity 1 is provided with a hollow shaft 10 along the axial direction thereof, the hollow shaft 10 is provided with a plurality of air inlets 1001 communicated with the generation cavity 1, and the hollow shaft 10 respectively extends out of the generation cavity 1 and is respectively connected with the first driving motor 18 and the pressure supply pipeline 3. Since the generation chamber 1 is provided in the horizontal direction, the length of the generation chamber 1 is not limited by the depth of water, and the length of the generation chamber 1 can be arbitrarily adjusted even in a shallow water environment. Of course, the problem of poor structural stability occurs if the length of the chamber 1 is too long, but this problem is not taken into account in the present application.

In this embodiment, because the generation cavity 1 is arranged along the horizontal direction, the problem that the air output and the bubble particle size at the upper and lower ends are inconsistent due to the large water pressure difference between the upper and lower ends of the generation cavity 1 when the generation cavity 1 is arranged along the vertical direction is solved, and when the generation cavity 1 is arranged along the horizontal direction, the pressure difference between the upper and lower parts of the generation cavity 1 depends on the diameter of the generation cavity 1.

Further, as shown in FIG. 1, the diameter of the generation lumen 1 is much smaller than the axial length of the generation lumen 1. Wherein the diameter of the generation chamber 1 is about 10cm and the axial length of the generation chamber 1 is greater than 1 m.

In the present embodiment, as shown in fig. 1, annular first blocking pieces 11 are respectively disposed on the outer wall of the generation chamber 1 and at both ends of the generation chamber 1 along the circumferential direction of the generation chamber 1, and the outer diameter of the first blocking pieces 11 is larger than the diameter of the generation chamber 1. When taking place the chamber 1 and rotate, can drive near the rotatory outer throwing of water, position near micro-fine bubble emergence layer 2 forms the negative pressure region, the regional formation of negative pressure can lead to being located the water supply that takes place the chamber 1 left and right sides to the negative pressure region, extrude the micro-nano bubble that just breaks away from micro-fine bubble emergence layer 2 that forms, the micro-nano minute bubble that leads to the part to cut out combines to form bigger bubble, especially position negative pressure at hugging closely micro-fine bubble emergence layer 2 outer wall is the biggest, the micro-nano bubble of cutting out is squeezed into bigger bubble again, and the rivers of the left and right sides can produce the offset in the intermediate position in the micro-fine bubble emergence layer 2 outside, combine into big bubble more easily. After having set up two first separation blade 11, rivers can only extrude produced micro-nano bubble in the region outside two first separation blade 11, and during micro-nano bubble had diffused bigger water this moment, concentration greatly reduced extruded the proportion of big bubble and also can reduce by a wide margin to greatly reduced rivers are to dashing the influence that causes micro-nano bubble. Wherein, the diameter of first separation blade 11 is big more, and is better to the effect that blocks of rivers, nevertheless because the water body of parcel can be driven between two first separation blades 11 and rotate along with taking place chamber 1, can have the shortcoming of increase energy consumption, so need balance between the particle diameter of production bubble and energy consumption.

Further, as shown in fig. 1, a circular second baffle 12 is disposed on the outer wall of the generation cavity 1 and between the two first baffles 11 along the circumferential direction of the generation cavity 1, and the diameter of the second baffle 12 is greater than that of the first baffles 11. Second separation blade 12 is located the intermediate position of the outer wall in chamber 1 takes place, because two first separation blade 11 can't increase its diameter in the consideration of consumption, can extrude rivers because of the negative pressure formation outside two first separation blade 11, so that rivers can take place the offset at the intermediate position of two first separation blade 11, the proportion that leads to the large bubble to produce increases, and add second separation blade 12 between two first separation blade 11, can effectively prevent the offset of rivers, second separation blade 12 set up except that increased the friction between its self and the water, can not lead to the large amount of increases of consumption.

Specifically, as shown in fig. 1, the device for generating micro bubbles further includes a first mounting base 13 and a first mounting frame 14, the bottom of the first mounting frame 14 is fixed on the first mounting base 13 through screw and nut matching, a first driving motor 18 is fixedly arranged at the top of the first mounting frame 14, a rotating shaft of the first driving motor 18 is arranged along the horizontal direction and is connected with one end of the hollow shaft 10 through a self-aligning coupler 15, the other end of the hollow shaft 10 is rotatably arranged on the first mounting frame 14 through a bearing structure, two sides of the hollow shaft 10, which are located on the bearing structure, are respectively sleeved with a circular first sealing ring 16, the inside of the hollow shaft 10 is communicated with the pressure supply pipeline 3 through a bearing seat and a sealing pipe 17, so as to ensure a good sealing effect.

In an optional embodiment of the present invention, as shown in fig. 2, the device for generating micro-bubbles includes a mounting plate 19 capable of vibrating along a horizontal direction, the micro-bubble generation layer 2 is located above the mounting plate 19, so as to form a generation chamber 1 by enclosing between the micro-bubble generation layer 2 and the top surface of the mounting plate, the generation chamber 1 is provided with an air inlet connected with the pressure supply pipeline 3, the mounting plate 19 is provided with a second driving motor 20 below, the second driving motor 20 is fixed at the bottom center position of the mounting plate 19, and a motor shaft of the second driving motor 20 is perpendicular to the surface of the mounting plate 19 arranged along the horizontal direction. The vibration force generated by the second driving motor 20 is distributed on the vertical surface of the motor shaft, the second driving motor 20 is vertically installed with the mounting plate 19 along the direction of the output shaft, and the centrifugal force generated by the eccentric block on the output shaft of the second driving motor 20 drives the whole mounting plate 19 to generate high-frequency reciprocating motion in the horizontal direction under the cooperation of the spring 21. Under the 19 high frequency reciprocating motion state of mounting panel, gaseous from the fine bubble take place layer 2 and see out and cut and form micro-nano bubble, because micro-nano bubble can be because capillary adsorption power and/or bubble and the effect of the surface tension between the micropore material layer 2 grow gradually and with bubble polymerization on every side, consequently, need not before micro-nano bubble becomes big bubble, mounting panel 19 micro-nano bubble can be cut by the water at the ascending high frequency reciprocating motion in-process of horizontal direction, micro-nano bubble takes originally ascending motion potential energy to get into the water with micro-nano bubble form. If in static water, mounting panel 19 is not when the vibration in the horizontal direction, the bubble that comes out from fine bubble emergence layer 2 is for sparse and rise fast, 19 horizontal vibration backs of mounting panel, because cut into micro-nano bubble, the bubble can become dense and slowly rise, therefore, in this embodiment, better effect has in the water that flows, the micro-nano bubble that forms can be washed away and dilute the diffusion to micro-nano bubble by rivers, micro-nano bubble is destroyed because of the inertia trend that continuous production causes to rise to the surface of water, the micro-nano bubble that is dispersed in the bigger water body on every side can present and disperse in aquatic and be in extremely slowly ascending state.

In the present embodiment, as the second driving motor 20 drives the mounting plate 19 to start vibrating, it is obviously observed that the bubbles generated by the micro-bubble generating layer 2 start to become smaller and denser, and as the vibration frequency increases, the bubbles further become smaller and denser, and after the vibration frequency increases to a certain value, the bubbles start to become larger and thinner due to mutual polymerization by collision, and the frequency further increases, and the bubbles become larger and thinner. Therefore, micro-nano bubbles with different particle sizes can be obtained by adjusting the vibration frequency of the mounting plate 19; the fine bubble generating material is different from another, and the particle size of the initial bubble is also slightly different from another fine bubble generating material of the same kind and from another fine bubble generating material of the same batch, and it is necessary to adjust the vibration frequency of the second driving motor 20 to ensure that the generated bubble is within a desired appropriate range.

Further, second driving motor 20 can be for but not limited to vibrating motor, the utility model discloses in utilize the centrifugal force that the high-speed rotation of eccentric block produced in the vibrating motor to combine the horizontal spring 21 of placing, drive mounting panel 19 and produce the vibration in the horizontal direction, different with the conventional use method of vibrating motor, the convention is that the spring is placed perpendicularly, and the shake about the output reaches the effect of screening object vibrations. This is the use method that combines the utility model discloses need to the vibrating motor novelty.

Specifically, as shown in fig. 2, the device for generating micro bubbles further includes a second mounting base 22 and a second mounting frame 23, the bottom of the second mounting frame 23 is fixed on the second mounting base 22 through screw and nut matching, the mounting plate 19 is a square or circular flat plate-shaped structure arranged along the horizontal direction, steel sheets are welded at the middle positions of the edges of the mounting plate 19 respectively, the steel sheets extend to the lower side of the mounting plate 19 along the vertical direction, each edge of the mounting plate 19 is provided with a spring 21 respectively (the spring 21 is connected with the mounting plate 19 through screw and nut matching), the other end of the spring 21 is connected with the second mounting frame 23, and the spring 21 is in a horizontal state below the liquid level. Of course, the mounting plate 19 may also be polygonal.

In an optional embodiment of the utility model, as shown in fig. 3, the device for producing micro bubbles includes the cavity stand 26 that sets up along vertical direction, the top of cavity stand 26 is sealed, the bottom is connected with supplying to press pipeline 3, supply to press pipeline 3 to stretch into the inside to cavity stand 26, the bottom of cavity stand 26 is provided with and can drives cavity stand 26 pivoted third driving motor 24, be connected with on the cavity stand 26 and take place chamber 1 rather than a plurality of emergence that inside is linked together, the top that each takes place chamber 1 covers respectively and is equipped with micro bubbles and takes place layer 2. In the use, third driving motor 24 drives cavity stand 26 rotatory, and each takes place chamber 1 and micro-fine bubble and takes place layer 2 along with cavity stand 26 synchronous rotation, and the gas in each chamber 1 of taking place emerges from micro-fine bubble and takes place layer 2 and is cut by the water, and gas gets into the water under the drive of the original power that makes progress of self, forms micro-nano bubble.

Further, as shown in fig. 3 and 4, the plurality of generation cavities 1 are arranged in a multi-layer interval manner in the vertical direction, and the generation cavities 1 in each layer are evenly distributed and spaced along the circumferential direction of the hollow upright post 26.

Further, the cross-section of the generation chamber 1 (i.e., the cross-section of the micro-bubble generation layer 2) may be, but is not limited to, rectangular in a spaced-apart arrangement. If the generation chamber 1 is a complete circular ring that is arranged around the outside of the hollow upright 26 along the circumference of the hollow upright 26, it has its own drawbacks: that is, the micro-nano bubbles generated by the inner ring of the micro-bubble generation layer 2 are easily thrown outwards (i.e. the micro-nano bubbles generated by the inner ring of the micro-bubble generation layer 2 are driven to move towards the outer ring of the micro-bubble generation layer 2) by the complete circular ring under the action of centrifugal force in the rotating process and collide with the micro-nano bubbles generated by the outer ring of the micro-bubble generation layer 2 to be gathered together, if the process is continued continuously, large-proportion large bubbles are formed, therefore, in an optional embodiment of the utility model, two adjacent micro-bubble generation layers 2 on the same layer can be arranged at intervals, which is beneficial to shortening the continuous process of collision and gathering, and the micro-nano bubbles are widely diffused into the water body before the large bubbles with the diameter larger than 100um are not formed, so that the collision probability is greatly reduced.
