Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
Unless otherwise expressly stated, throughout the specification and claims, the term "includes" or its variations such as "contains" or " comprising" and the like will be understood to include the stated element or component and not to exclude other elements or other components.
According to Figures 1 to 4, this embodiment provides a micro-nano bubble-cavitation nozzle. The micro-nano bubble-cavitation nozzle comprises a pipe body 1, a primary cavitation plate 2 and a secondary cavitation assembly 3. The pipe body 1 is equipped with a cavity 11 for fluid flow, the left end of the pipe body 1 is used to receive the fluid mixing with gas and liquid, and the right end is the nozzle for gas and liquid injection, i.e., the outlet end. The primary cavitation plate 2 and secondary cavitation assembly 3 are located in the cavity 11 of pipe body 1. The fluid mixing gas and liquid passes through the primary cavitation plate 2 to produce primary cavitation, and the fluid passes through the secondary cavitation assembly 3 to produce secondary cavitation.
The specific structure is as follows: The pipe body 1 is provided with a pipe cavity 11 for fluid flow, the left end of the pipe body 1 is the inlet end and is used to receive the fluid mixed with gas and liquid, the right end is the gas-liquid injection nozzle and is the outlet end. The cavity 11 of pipe body 1 is fixed with a primary cavitation plate 2, the primary cavitation plate 2 is set near the inlet end of the pipe body 1. The primary cavitation plate 2 is equipped with through-holes 21 with a smaller aperture in the front and a larger aperture in the back, with the end of the smaller aperture being the inlet end 22 and the end of the larger aperture being the outlet end 23. The fluid mixing gas and liquid enters from the end of the through-hole 21 with a smaller diameter and exits from the end with a larger diameter to produce cavitation. The fluid mixing gas and liquid pass through the through-hole with smaller aperture in the front and larger in the back, change the cross-section through which the water flow. The increase in cross-section causes a decrease in pressure and produces primary cavitation under water pressure. The outlet end of the primary cavitation plate 2 is equipped with a secondary cavitation assembly 3 and the secondary cavitation assembly 3 is fixed in the cavity 11 in the pipe body 1. The secondary cavitation assembly 3 and the primary cavitation plate 2 are spaced apart to form a cavitation space 12. The secondary cavitation assembly 3 comprises at least one diversion pair, and each diversion pair includes two diversion plates mounted in opposite directions: the first diversion plate 31 and the second diversion plate 32. The first diversion plate 31 and the second diversion plate 32 have the same structure. Taking the structure of the first diversion plate 31 as an example, there is a diagonally open through-hole 311 or/and a diagonally open amplification hole along the circumference direction of the first diversion plate 31. The diversion plate in this embodiment is equipped with a diagonally open through-hole. During assembly, there is a space 13 between the first diversion plate 31 and the second diversion plate 32. The first diversion plate 31 and the second diversion plate 32 are mounted in opposite directions. The direction of the diagonally open through-hole on the inlet end of the second diversion plate 32 is the same as that of the outlet end of the first diversion plate 31. For example, the diagonally open through-holes on the outlet end of the first diversion plate 31 are aligned counterclockwise, and the diagonally open through-holes on the inlet end of the second diversion plate 32 are also aligned counterclockwise.
After primary cavitation, the fluid diffuses in the cavitation space 12 and rotates and jets along the inclined direction of the diagonal hole 311 in the first diversion plate 31, causing rapid rotation under water pressure. It rotates in the space 13 between the first diversion plate 31 and the second diversion plate 32, forming a fluid vortex. The inclined direction of the diagonal hole on the inlet end of the second diversion plate 32 is the same as that of the outlet end of the first diversion plate 31, and the direction of fluid flow is opposite to that of the first diversion plate 31. A pair of diversion plates directs the fluid to rotate in different directions in the direction of the water flow, resulting in secondary cavitation of the water vortex and the formation of smaller micro-nano bubbles. The micro-nano bubble-cavitation nozzle of the present invention generates bubbles by cavitation of the primary cavitation plate, and after secondary cavitation assembly, the fluid vortex formed after breaking up the primary cavitation generates secondary cavitation. The design of this stmcture allows the nozzle flow of micro-nano bubbles to be increased and the pressure loss of the pump to be reduced. It is also possible to set more than one diversion pair, such as two pairs of diversion plates, as needed.
Preferably, there are multiple through-holes 21 on the primary cavitation plate 2. In the above technical solutions, the multiple through-holes on the primary cavitation plate 2 are arranged in a circular pattern, forming multiple injection holes arranged in an annular pattern. In this embodiment, the through-holes 21 are arranged as two circular injection holes 24 and 25. Multiple through-holes are evenly distributed on the primary cavitation plate 2, so that the bubbles formed by primary cavitation are uniformly dispersed and the flow rate is high.
Preferably, the through-holes on the primary cavitation plate 2 are diagonally open. The diagonally open through-holes 21 on the primary cavitation plate 2 are oriented in the direction of the diameter towards the outer edge of the plate at the outlet enddiagonally open through-holes. In the limited space of the plate, the length of the through-holes 21 is extended, so that the fluid pressure increases in the compressed section passing through the pipe with a smaller aperture, and the pressure decreases in the increased section, and the pressure difference is increased, so that more bubbles are formed in the fluid.
Preferably, the through-hole 21 on the primary cavitation plate 2 comprises at least one primary through-hole 211 and several secondary through-holes 212; the aperture of the primary through-hole 211 is larger than that of the secondary through-holes 212 and the primary through-hole 211 is located in the middle of the primary cavitation plate, and multiple secondary through-holes 212 are set around the primary through-hole to form multiple circularly arranged injection holes. The middle of the primary cavitation plate is equipped with a primary through-hole 211 in the middle, and there are several secondary through-holes 212 around the primary through-hole 211, so that the fluid diffuses in a dispersive pattern after passing through the primary cavitation plate 2.
Preferably, the first diversion plate 31 and the second diversion plate 32 have the same structure. Taking the first diversion plate 31 as an example, the first diversion plate 31 has multiple diagonally open holes 311, and the holes are slanted in the direction of the circumference of the plate, and are tilted in the same direction around the center of the diversion plate 31, forming multiple circularly arranged injection holes. The diagonally open through-holes 311 on the diversion plate 31 are through-holes with uniform apertures or/and diagonally open amplification holes. In this embodiment, through-holes 311 are arranged to form circular injection holes 312 and 313. There is a primary through-hole 314 in the middle of the diversion plate with a smaller aperture in the front and a larger aperture in the back. The primary through-hole 314 is set in a positive circle, with the center of the circle coinciding with the axis of the plate.
Preferably, in the diversion pair, the end with the smaller aperture of the primary through-hole 314 in the first diversion plate 31 near the primary cavitation plate 3 is the liquid inlet end 315, the end with the larger aperture is the discharge end 316. In the second diversion plate 32, the end with the larger aperture in the primary through-hole is the inlet end 321, and the end with the smaller aperture is the outlet end 322.
The foregoing description of specific exemplary embodiments of the present invention is for the purpose of illustration and example. These descriptions are not intended to limit the invention to the precise form disclosed, and it is clear that many changes and variations can be made in accordance with the above teachings. The exemplary embodiments have been selected and described for the purpose of explaining the particular principles of the invention and their practical application, thereby enabling those skilled in the art to implement and utilize various exemplary embodiments of the invention, as well as various options and variations.
