Background

The air flotation machine is equipment for realizing solid-liquid or liquid-liquid separation by utilizing the buoyancy and adhesion of bubbles, and has quite wide application in the treatment of water supply, domestic sewage and industrial wastewater. At present, a common air floatation machine mainly comprises two modes of dissolved air floatation and aeration air floatation. The dissolved air flotation is to dissolve gas into water by the rising pressure, then release the gas in a low-pressure environment, and separate the gas out of the water to form micro bubbles, thereby generating an air flotation effect. The aeration air floatation is to convey the gas into the water body through a blower, and an aeration device is generally arranged to cut and disperse the gas.

At present, bubbles generated in a gas dissolving and aerating mode have larger volume, high rising speed in water and short residence time, so that the treatment efficiency is low. The particle size of micro-nano bubbles is generally smaller than 100 mu m, the floating speed in water is low, the residence time is long, and bubbles with small particle size also provide a larger gas-liquid contact area, so that the adhesion of suspended particles in water is more beneficial. Therefore, in order to improve the treatment efficiency and the treatment effect of the air-floatation technique, an integrated device which relies on micro-nano bubbles to lift the air-floatation effect needs to be studied.

In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

The micro-nano bubble-air floatation integrated apparatus 100 according to an embodiment of the present utility model is described below with reference to the accompanying drawings.

According to an embodiment of the present utility model, a micro-nano bubble-air floatation integrated device 100, as shown in fig. 1, includes: an air floatation tank 1, a vibration foaming mechanism 60 and an inlet pipeline 3.

The vibrating bubbling mechanism 60 is provided in the air flotation tank 1, and the vibrating bubbling mechanism 60 includes a bubbling flow path 610 and a vibrator 65. The peripheral wall 615 of the bubbling flow channel 610 comprises a corrugated plate 6153, and a plurality of shearing holes 611 for draining liquid into the air floatation tank 1 are arranged on the corrugated plate 6153. The vibrator 65 includes a spring body 653, and the spring body 653 is located within the foam flow channel 610 and is coupled to the corrugated plate 6153. One end of the inlet pipe 3 is positioned outside the floatation tank 1, and the other end of the inlet pipe 3 is connected with an inflow port 616 of the vibration foaming mechanism 60 so as to convey the liquid with bubbles to the foaming flow passage 610.

The vibration body 65 is made of a spring body 653, and the spring body 653 can be used for simple harmonic vibration. As is well known to those skilled in the art, the magnitude of the force applied to an object is proportional to the displacement, and the direction is opposite, so that vibration with such characteristics is called simple harmonic motion, which can also be called sinusoidal vibration, and a representative model of the simple harmonic vibration includes spring vibrator motion and simple pendulum motion, and in general, the simple harmonic vibration can be continuously converted in the motion of kinetic energy and potential energy of the object over a period of time.

The micro-nano bubble-air floatation integrated device 100 operates as follows:

the liquid containing bubbles flows into the foaming flow passage 610 through the inlet pipe 3, and is limited by the shearing holes 611, the liquid can only carry away small-particle-size bubbles flowing from the shearing holes 611 to the floatation tank 1, and large-particle-size bubbles are blocked in the foaming flow passage 610.

At the same time, the flow is accompanied by turbulence and turbulence during the flow. After flowing into the frothing channel 610, the liquid will impact the peripheral wall 615 of the frothing channel 610. After impacting the corrugated plate 6153, the corrugated plate 6153 deforms, driving the spring body 653 to expand and contract.

After the spring body 653 is compressed or stretched, the simple harmonic vibration characteristic of the spring body 653 can repeatedly extend and shorten the spring body 653, and drive the corrugated plate 6153 to stretch. The spring 653 can continuously stretch and retract to drive the corrugated plate 6153 to continuously reciprocate to squeeze and deform when the liquid flows, and the spring 653 and the corrugated plate are mutually reinforced. Particularly, the driving action of the liquid flow on the corrugated plate 6153 is uneven, and the non-uniformity of the liquid flow driving can be compensated under the simple harmonic vibration characteristic of the spring body 653. When the corrugated plate 6153 is pulled by the spring body 653 to make simple harmonic vibration, the internal volume of the foam flow passage 610 is changed. When the peripheral wall 615 vibrates in the direction of the inside of the foam flow path 610, the inner volume of the foam flow path 610 is reduced, and the liquid in the foam flow path 610 is compressed. When the peripheral wall 615 vibrates in the direction of the outside of the bubble flow channel 610, the inner volume of the bubble flow channel 610 increases, the liquid in the bubble flow channel 610 is released, and bubbles are present in the environment where the pressure is continuously changed.

By the simple harmonic vibration of the spring 653, the bubbles mixed in the water can be secondarily crushed by the small hole shearing action, and bubbles having smaller particle diameters can be generated.

The core principle of this vibrating bubbling mechanism 60 is to use simple harmonic vibration (mainly the spring body 653) and small hole shearing to secondarily crush bubbles mixed in the liquid phase. The vibration crushing is driven by hydraulic impact and vibration of the spring body, and after bubbles in water are crushed by the vibration due to simple harmonic vibration, the bubbles are further crushed by small hole shearing and extrusion in the discharging process, so that bubbles with smaller particle sizes are generated.

When the corrugated plate 6153 is adopted, the vibration of the corrugated plate 6153 can further enhance the crushing effect on bubbles, particularly the corrugated plate 6153 can be deformed in the movement, and the shearing holes 611 can be deformed to enhance the crushing effect on the bubbles.

When the initial power of the vibrator 65 is only the impact force of the liquid flow, not only the structure of the vibration foaming mechanism 60 is greatly simplified, but also the vibration foaming mechanism 60 does not need to use electricity, and the electricity consumption of the vibration foaming mechanism 60 is greatly reduced. The vibration of the vibrating bubbling mechanism 60 does not require an electronically controlled device drive, so that the vibrating bubbling mechanism 60 is very safe to use.

The details of the flow of liquid through the shear orifice 611 are further described in connection with fig. 5. When the size of the bubbles is smaller than or close to the size of the shearing holes 611, these small size bubbles can pass through the shearing holes 611 rapidly with the liquid flow. When the particle size of the bubbles is much larger than the aperture of the shearing hole 611, the bubbles with larger particle size are blocked in the foaming flow path 610 and continue to be kneaded. When the particle size of the air bubbles is slightly larger than the aperture of the shearing hole 611, as in fig. 5, two air bubbles flow toward the shearing hole 611, the former air bubble passes through the shearing hole 611, and the liquid in the shearing hole 611 is taken away by the former air bubble, so that the shearing hole 611 forms negative pressure, and the liquid flows on both sides of the latter air bubble flow toward the shearing hole 611 to form inner-winding turbulence, and the latter air bubble is easily split from the middle. After the previous bubble continues to flow forward for a period of time, sufficient liquid flow is supplemented at the shearing hole 611, the next bubble moves closer to the shearing hole 611, and high pressure is formed at the shearing hole, so that the liquid flow flows towards the two sides of the next bubble to form external turbulence, and the next bubble is easily torn open towards the two sides.

The micro-nano bubble-air floatation integrated device 100 adopting the vibration foaming mechanism 60 has a good air floatation effect. The micro-nano bubbles have small particle size, large specific surface area and relatively large air content, so that the effect is relatively remarkable when the micro-nano bubbles are applied to air floatation in sewage treatment.

In some embodiments, as shown in fig. 2, the peripheral wall 615 of the frothing channel 610 includes two opposing corrugated plates 6153, with a spring body 653 connected between the two corrugated plates 6153. Thus, the same spring 653 can drive the corrugated plates 6153 at two sides to vibrate in a simple harmonic manner, so as to further strengthen the crushing effect on bubbles. And the area of the corrugated plate 6153 can be increased, so that the layout area of the shearing holes 611 is increased, and the yield of microbubbles is increased.

Specifically, as shown in fig. 3, the vibrating bubbling mechanism 60 may be integrally formed as a cylindrical body, and the peripheral wall 615 of the bubbling flow path 610 includes upper and lower side plates 6151 and a sealing plate 6152 connected between the two side plates 6151. At least part of the two side plates 6151 is a corrugated plate 6153, the spring body 653 is connected between the two side plates 6151, and the two side plates 6151 are provided with shearing holes 611. Alternatively, the peripheral sealing plate 6152 may also be a corrugated plate 6153.

As shown in fig. 3, the water flow enters the vibrating foaming mechanism 60 from the center, so that the foaming flow channel 610 is in a circular ring shape as a whole, the center of the foaming flow channel 610 is an inflow port 616, and the water flow flows from inside to outside along the radial direction. Is repeatedly pressed by the corrugated plate 6153 in the flowing process, and flows out of the shearing holes 611 on the side plate 6151. During the flow, the bubbles are gradually broken from large to small and carried out of the shearing holes 611 by the water flow.

Further, as shown in fig. 4 (a) and 4 (b), the corrugated plate 6153 has peaks and valleys, and the corrugated plate 6153 is provided with shearing holes 611, and the shearing holes 611 are located at the peaks and/or the valleys of the corrugated plate 6153. It can be understood that in the process of repeatedly moving and deforming the corrugated plate 6153 by pulling, the deformation amount at the wave crest and the wave trough is large, and the extrusion and tearing forces on the bubbles are strongest, so that the shearing holes 611 are formed, and the crushing effect on the bubbles in water can be maximized.

In some embodiments, the perimeter wall 615 of the foam flow channel 610 includes two opposing corrugated plates 6153 with a plurality of spring bodies 653 connected between the two corrugated plates 6153. Here, the number of the spring bodies 653 can be reasonably set according to the water pressure, and the plurality of spring bodies 653 are beneficial to improving the supporting effect on the corrugated plate 6153, so as to drive the corrugated plate 6153 to integrally move. Alternatively, the number of spring bodies 653 can be 4-6. The spring 653 can be disposed at the edge of the side plate 6151, which is beneficial to driving the whole side plate 6151 to vibrate in a simple harmonic manner.

Specifically, the spring bodies 653 are plural and spaced apart around the inflow port 616, and since the inflow port 616 is at the center, the water flows radially after flowing in from the inflow port 616. The plurality of spring bodies 653 distributed in this way is beneficial to moving the corrugated plate 6153 integrally, and improves the vibration crushing effect of the whole foaming flow passage 610 on bubbles.

More specifically, the corrugated plate 6153 is an upper and lower circular plate, and the corrugations are annularly distributed. The circular corrugated plates 6153 are beneficial to improving the stress balance of the corrugated plates 6153, and the annular distribution of the corrugations is beneficial to improving the structural strength of the corrugated plates 6153 and reducing the bending deformation probability of the corrugated plates 6153. The shear holes 611 are located at the valleys/peaks, and the shear holes 611 have a diameter of 0.001-0.5mm. Further alternatively, the shear holes 611 have a pore size of 0.01-0.1mm. For example, the shear holes 611 have a diameter of 0.01mm, 0.002mm, 0.005mm, 0.007mm, 0.011mm, 0.028mm, 0.033mm, 0.045mm, 0.05mm, 0.06mm, 0.085mm, 0.1mm, and the like.

In some embodiments, the two side plates 6151 are spaced 0.1-10mm apart, i.e., the two corrugated plates 6153 are spaced 0.1-10mm apart. Further alternatively, the two side plates 6151 are spaced 0.1-1mm apart. For example, the two side plates 6151 may have a pitch of 0.1mm, 0.2mm, 0.35mm, 0.45mm, 0.55mm, 0.6mm, 0.8mm, 1mm, or the like.

In the micro-nano bubble-air floatation integrated device 100 of this embodiment, the running water pressure can be 0.14-2.5Mpa, and the micro-nano bubble can work normally under the normal water pressure of tap water, in particular, when the water pressure is higher, the micro-bubbles are more compact and uniform.

The gas content (volume fraction) in the liquid entering the frothing channel 610 may be between 5% and 50%. Further alternatively, the gas content (volume fraction) in the liquid entering the frothing channel 610 is 15-30%, such as 15%, 20%, 25%, 30%, etc.

In addition, according to the simulation by the team of the inventors, the ratio of the bubble particle diameter D to the aperture D of the shear hole 611 may be selected to be D/d=2 to 8. Further alternatively, the ratio of the bubble particle diameter D to the aperture D of the shearing hole 611 may be 4, whereby the crushing effect is preferable. In the simulation, it was found that when the ratio of the bubble particle diameter D to the pore diameter D was less than 2, the bubbles were deformed only when passing through the small pores, and then when the corrugated plate was far away, the bubbles were restored to a circular shape, and the corrugated vibration and the small pore shearing had no crushing effect. In this connection, in the actual use of the present embodiment, the installation pore diameter d of the shear pore 611 may be selected according to the desired bubble particle diameter.

In some embodiments, the micro-nano bubble-air floatation integrated device 100 comprises a water pump 4, a water inlet pipe 5 and an air inlet pipe 6. The water pump 4 is connected in series on the inlet pipeline 3, the water inlet pipe 5 is connected with the inlet pipeline 3, and the air inlet pipe 6 is connected with the inlet pipeline 3. That is, the water stream mixes with the air stream in the inlet conduit 3 to form a bubble-bearing water stream. The water pump 4 is arranged to drive water flow along the inlet pipe 3 towards the vibrating and frothing mechanism 60, especially when gas is mixed with water at the upstream of the water pump, the operation of the water pump causes larger shearing force to be formed inside, and after mixing, large bubbles are formed and smaller bubbles are dispersed in the water under the strong breaking action of the water pump.

The micro-nano bubble-air floatation integrated device 100 further comprises a calandria 24 which is positioned in the air floatation tank 1 and connected with the inlet pipeline 3, and a plurality of vibration foaming mechanisms 60 are connected to the calandria 24. For example, in FIG. 1, gauntlet 24 has a main tube and two rows of connected sub-tubes, each sub-tube being connected to a vibrating bubbling mechanism 60. Thus the inlet pipeline 3 can be directly connected with the calandria 24, and the connection difficulty is reduced.

The vibration foaming mechanism 60 can be flexibly arranged in the air floatation tank 1 according to the size of the air floatation tank 1 and the related water quality characteristics, and can be arranged in an array, randomly or at fixed points.

In some embodiments, the water pump 4 is a multistage vane pump that is flanged to the inlet pipe 3.

Specifically, the air inlet pipe 6 is connected to the inlet and the outlet of the water pump 4 through the tee 7, so that the air can enter the upstream of the water pump 4 or the downstream of the water pump 4 during air inlet.

Specifically, branch pipes 72 of the tee 7 connecting the inlet and the outlet of the water pump 4 are respectively provided with a control valve 71. For ease of understanding, the front valve 711 and the rear valve 712 are referred to, respectively.

When the multistage impeller water pump works, water enters from the water inlet pipe 5, the front valve 711 is opened, the rear valve 712 is closed, negative pressure is formed at the joint of the water inlet pipe 5 and the front valve 711, and air is conveyed into the inlet pipeline 3 by utilizing the negative pressure, so that a gas-water mixture is formed. After entering the multistage impeller pump, the gas is cut and broken into bubbles dispersed in water under high-speed rotation stirring of the impeller, and is sent to the vibration foaming mechanism 60. The two branch pipes 72 of the tee 7 are provided with a front valve 711 and a rear valve 712, which are used for adjusting the air-water mixing ratio and controlling the opening and closing thereof according to the water outlet effect.

In some embodiments, as shown in fig. 1, the micro-nano bubble-air floatation integrated device 100 further includes a delivery assembly 8, where a delivery port 801 of the delivery assembly 8 is connected to the air floatation tank 1, such as a drug may be delivered to the air floatation tank 1 by the delivery assembly 8. By arranging the throwing component 8, the automatic processing function of the air floatation tank 1 can be increased.

In some embodiments, as shown in fig. 1, the launch assembly 8 comprises: the primary mixer 81 and the secondary mixer 82 are connected in sequence, the outlet of the primary mixer 81 is connected with the inlet of the secondary mixer 82, and the throwing outlet 801 is arranged on the secondary mixer 82. Thus, the medicine and the liquid can be fully mixed during the medicine adding process.

Specifically, the primary mixer 81 is provided with the rotatable stirring paddle 83, and the stirring paddle 83 rotates under the impact of the liquid inlet of the primary mixer 81, so that stirring can be performed without an electric control device, and the cost is reduced. That is, the internal components of the primary mixer 81 are a hydraulic stirring paddle 83 capable of self-stirring by hydraulic impact, and the medicine added to the air floatation process completes the primary mixing.

More specifically, the secondary mixer 82 is fixedly provided therein with a stirring vane 84. That is, the internal components of the secondary mixer 82 are SV static mixers, and the medicine flows into the secondary mixer 82 in the primary mixer 81, through which secondary mixing is completed.

Optionally, the inlet of the primary mixer 81 is disposed at the bottom of the primary mixer 81, and the outlet of the primary mixer 81 is located at or near the top of the primary mixer 81, so that when the water flows upward against gravity, the water flows easily generate turbulence, and the mixing effect is improved.

Optionally, the inlet of the secondary mixer 82 is located at or near the top of the secondary mixer 82, with the bottom of the secondary mixer 82 exiting. So that the medicine can smoothly enter the floatation tank 1.

Specifically, the water in the primary mixer 81 flows from the top into the secondary mixer 82 by gravity overflow.

In conclusion, the micro-nano bubble-air floatation integrated device 100 with low energy consumption fully utilizes the shearing force of impeller stirring, spring elasticity and shearing holes to secondarily crush bubbles to generate micro-nano bubbles, so that the comparison area and the air content of the bubbles in air floatation are greatly improved, and the air floatation effect is remarkably improved. The energy consumption of the air floatation process is reduced by the vibrating bubbling mechanism 60 and the gravity overflow dispensing assembly 8.

A micro-nano bubble-air floatation integrated device 100 is described below in connection with the embodiment of fig. 1.

As shown in fig. 1, the micro-nano bubble-air floatation integrated device 100 comprises an air floatation tank 1, a vibration foaming mechanism 60, an inlet pipeline 3, a multi-stage impeller pump, a water inlet pipe 5, an air inlet pipe 6, a three-way pipe 7, a control valve 71 and a throwing component 8. The connection is shown in fig. 1.

Wherein, raw water flows to the inlet pipeline 3 under the action of the multi-stage impeller pump, the rear valve 712 is closed, at the moment, negative pressure is formed inside the inlet pipeline 3, and air is brought into the inlet pipeline 3 to form a gas-water mixture.

The gas-water mixture is mixed once in a multistage impeller pump. The impeller rotation speed of the multistage impeller pump is high, a large shearing force can be formed in the pump, and large bubbles form small bubbles to be dispersed in water under the strong crushing action of the multistage impeller.

The once mixed gas-water mixture is pumped into the inlet pipe 3, where the gas-water mixture is subjected to a secondary mixing. When the air-water mixture enters the pipe 24 with a certain water head under the action of the pump pressure and enters the vibration foaming mechanism 60 from the pipe 24, the pipe diameter is reduced, the flow speed is increased, so that the air-water mixture can impact the vibration foaming mechanism 60, the spring body 653 is stretched, the pipeline pressure is further increased until the tension generated by the spring body 653 pulls back the two corrugated plates 251 of the vibration foaming mechanism 60, the air-water mixture flows out from the shearing holes 611, the pipeline is decompressed, and then the hydraulic action re-impacts the vibration foaming mechanism 60. The reciprocating vibration is formed in this way, and the bubbles are further mixed and dispersed under the action of the instrument breaking and the micro-pore canal, so that a mixture of milky micro-nano bubbles and liquid is formed and released through the shearing holes 611.

A delivery assembly 8 is arranged above the air floatation tank 1, and when medicines are delivered, the delivery assembly is conveyed into a primary mixer 81 through a water pump, and a hydraulic stirring paddle 83 arranged in the delivery assembly is used for self-stirring under the pushing action of hydraulic power, so that primary mixing of the medicines is completed; and then overflows by gravity into the secondary mixer 82. The secondary mixer 82 is provided with an SV static mixer, and the medicines overflowed into the secondary mixer 82 by gravity are discharged to complete secondary mixing.

The micro-nano bubble-air floatation integrated device 100 can be applied to the field of water treatment, can be used in the treatment of water supply, urban domestic sewage and industrial wastewater, and can remarkably improve the air floatation effect and reduce the operation energy consumption.
