Detailed Description
The invention is explained in more detail below with reference to the figures and examples. The described embodiments are only some embodiments of the invention, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, a micro-nano bubble nozzle comprises a first nozzle base body 1 with a liquid inlet channel 3 and a second nozzle base body 2 with a gas-liquid output channel 4, wherein the first nozzle base body 1 can be partially sleeved with the second nozzle base body 2 to form a gas-liquid circulation stirring chamber 5; the first nozzle base body 1 is provided with an air inlet 6 which can supply air to the gas-liquid circulation stirring chamber 5; the liquid inlet channel 3, the gas-liquid circulation stirring chamber 5 and the gas-liquid output channel 4 are communicated with each other, and the liquid inlet channel 3 and the gas-liquid output channel 4 are located on the same axis.
Specifically, as shown in fig. 4, liquid enters the gas-liquid circulation stirring chamber 5 along the liquid inlet channel 3, gas enters the gas-liquid circulation stirring chamber 5 along the gas inlet 6, and since both of the liquid and the gas have certain pressure in the entering process, the liquid and the gas can be fully mixed, collided and stirred in the gas-liquid circulation stirring chamber 5, and finally are discharged outwards along the gas-liquid output channel 4 in the form of micro-nano bubbles.
In addition, in the gas-liquid circulation stirring chamber 5, the gas and the liquid are sufficiently mixed to form a circulation flow. The circulation flow is a series of flows in which the liquid is inverted by collision with the gas in the opposite direction during the flow, and the liquid flows again to the inlet 3 along the inner wall of the gas-liquid circulation stirring chamber 5.
The device can control the speed of the generated circular flow to a certain extent, including from low speed to high speed, through the supply amount and pressure of liquid and gas. Therefore, the high-speed circulating flow can be formed by further increasing the speed of the circulating flow by adjusting the supply amount and pressure of the liquid and the gas, and further the desired micro-nano bubbles can be manufactured.
Here, the gas supplied from the gas supply chamber to the gas-liquid circulation stirring chamber 5 is subdivided by turbulence generated in the gas passage 16 between the gas supply chamber 15 and the gas-liquid circulation stirring chamber 5, and is stirred and sheared in the circulation flow. When part of the liquid flows reversely due to the air flow II and collides with the liquid continuously flowing in from the liquid inlet channel 3, the liquid is further subdivided due to the generation of the turbulent flow. The gas in the circulating flow is further subdivided by the external gas or the external liquid flowing into the gas-liquid circulating stirring chamber 5 from the liquid inlet channel 3. The mechanism for generating the subdivided bubbles in the series of processes is the characteristic of a composite multistage turbulent flow type (circulating flow type) micro-nano bubble nozzle, and has the advantages which are not possessed by other nozzles.
As an optimization of the device, as shown in fig. 2, 3, 5, 6 and 7, the first nozzle base body 1 is in a semi-closed sleeve shape, and includes an inner cavity 7 capable of partially sleeving the second nozzle base body 2, and the liquid inlet channel 3 is located at the axis position of the inner cavity and is communicated with the inner cavity 7; the second nozzle base body 2 is cylindrical, the gas-liquid output channel 4 is positioned at the axis position of the second nozzle base body 2, is in a venturi tube shape and comprises a conical convergence part 8, a cylindrical throat part 9 and a conical diffusion part 10 which are sequentially connected, the conical convergence part 8 corresponds to a gas-liquid input port 11 (positioned in the inner cavity 7) of the second nozzle base body 2, and the conical diffusion part 10 corresponds to a gas-liquid output port 12 of the second nozzle base body 2; after gas and liquid are fully mixed, collided and stirred in the gas-liquid circulation stirring chamber 5, the gas and the liquid continuously flow to the gas-liquid output port 12 along the gas-liquid input port 11 in the form of micro-nano bubbles and are finally discharged outwards. In the embodiment, the gas-liquid output channel 4 is arranged in a venturi tube shape (comprising a conical convergence part 8, a cylindrical throat part 9 and a conical diffusion part 10 which are connected in sequence), the venturi tube has the main advantage of simple device, and secondly, because the diffusion section (the conical diffusion part 10) of the venturi tube gradually decelerates the fluid, the turbulence is reduced, so that the pressure head loss is small and does not exceed 10-20% of the pressure difference between the inlet (the conical convergence part 8) and the throat (the cylindrical throat part 9); in addition, the device can not be blocked after long-term use, and the service life of the device is prolonged.
As a further optimization of the gas-liquid outlet channel 4, the length of the conical convergent part 8 is greater than the length of the cylindrical throat 9, and the length of the conical divergent part 10 is greater than the length of the conical convergent part 8.
As an optimization of the second nozzle base body 2, a connected flange 13 and an annular groove 14 are arranged along the outer wall of the second nozzle base body 2 corresponding to the end of the inner cavity 7, and an air supply chamber 15 is formed between the annular groove 14 and the inner wall of the inner cavity 5; an air channel 16 is formed between the flange 13 and the inner wall of the inner cavity 5; the gas-liquid circulation stirring chamber 5 is formed between the gas-liquid input port 11 and the inner cavity 7, and the gas supply chamber 15, the gas passage 16 and the gas-liquid circulation stirring chamber 5 are communicated with each other; the air inlet 6 corresponds to the air supply chamber 15.
The structure of the present embodiment is mainly to provide a gas supply scheme, in which gas is temporarily stored in the gas supply chamber 15, and the gas source in the gas supply chamber 15 is continuously delivered into the gas-liquid circulation stirring chamber 5 at a certain pressure through the gas passage 16, and the narrow gas passage 16 can increase the pressure during the gas delivery process, and can flow into the gas-liquid circulation stirring chamber 5 at a high pressure and a high speed, and when encountering liquid, the gas can collide, mix and stir violently, and form turbulent flow.
In order to facilitate the smooth transmission of gas, the adjacent part of the flange 13 and the annular groove 14 adopts an arc-shaped angle design, so that the resistance problem caused by a right-angle design is effectively avoided.
For better control of the gas (or gas flow), the length of the flange 13 is greater than the length of the annular groove 14; the diameter of the air channel 16 is less than or equal to 1/2 of the diameter of the air supply chamber 15.
As a control form for interaction between the entering gas and the liquid in the gas-liquid circulation stirring chamber 5, the gas-liquid circulation stirring chamber 5 is subjected to violent collision under the action of self pressure, and the structure inside the gas-liquid circulation stirring chamber 5 is improved, namely, at least one right-angle groove 17 is formed in the gas-liquid input port 11, the right-angle groove can further block and reverse the gas and the liquid, so that sufficient mixing and stirring of the gas and the liquid are increased, the turbulence degree is improved, and formation of micro-nano bubbles is facilitated.
In the present embodiment, the distance between adjacent rectangular grooves 17 is the same.
As a further optimization of the liquid inlet channel 3, the liquid inlet channel 3 includes a first liquid inlet 22 communicated with the outside and a second liquid inlet 23 communicated with the inner cavity 7, a junction of the first liquid inlet 22 and the second liquid inlet 23 is an inclined plane (the inclined plane is provided to reduce the blockage of the inflowing liquid), and a junction of the second liquid inlet 23 and the inner cavity 7 is an inclined plane (the inclined plane is mainly beneficial to the sufficient impact, mixing and stirring of the gas and the liquid); the inner diameter of the first liquid inlet 22 is larger than that of the second liquid inlet 23 (the liquid flowing in can be pressurized, so that the gas-liquid circulation stirring chamber 5 can be stirred with the gas); the inner diameter of the inner cavity 7 is larger than the inner diameter of the second liquid inlet 23.
As shown in fig. 4, the micro-nano bubble nozzle provided by this embodiment, when in use, two ends need to be connected with a pipeline, specifically: the outer wall of the first spray head base body 1 corresponding to the liquid inlet channel 3 is provided with a first pipeline connecting part 19 for connecting a first pipeline 18; the outer wall of the second nozzle base body 2 corresponding to the gas-liquid output channel 4 is provided with a second pipeline connecting part 21 for connecting a second pipeline 20; the pipe cavities of the first pipeline 18, the liquid inlet channel 3, the gas-liquid circulation stirring chamber 5, the gas-liquid output channel 4 and the second pipeline 20 are communicated with each other.
