液体处理部124包括截面沿由进液口至出液口的方向(即箭头500的方向)逐渐缩小的收缩段121、与吸气口连通的混合段122、截面沿由进液口至出液口的方向(即箭头500的方向)逐渐增大的扩张段123。The liquid processing portion 124 includes a constricted section 121 whose cross section is gradually reduced in a direction from the liquid inlet port to the liquid outlet port (ie, the direction of the arrow 500), a mixing section 122 communicating with the suction port, and a cross section from the liquid inlet port to the liquid discharge port. The expansion section 123 of the mouth direction (i.e., the direction of the arrow 500) gradually increases.
在本实施例中,吸气孔115贯通至混合段122,由于混合段122在液体处理部124中截面最小,因此,吸气孔115贯通至混合段122,也更利于气液充分混合。In the present embodiment, the air intake hole 115 penetrates into the mixing section 122. Since the mixing section 122 has the smallest cross section in the liquid processing section 124, the air intake hole 115 penetrates into the mixing section 122, which is more advantageous for the gas-liquid to be sufficiently mixed.
另外,吸气孔115也可以设置为沿外部壁至液体处理部124,截面逐渐缩小的形状或者在外部壁处设置倒角,以保证吸入更多的气体。In addition, the suction holes 115 may also be disposed along the outer wall to the liquid treatment portion 124, the shape of the section being tapered or the chamfering at the outer wall to ensure that more gas is sucked in.
进一步地,发生器主体110外部壁设置有环状的凹槽114,并将吸气孔115设置在凹槽114内。当微纳米气泡发生器100安装至别的装置后,设置凹槽114可以保证不管微纳米气泡发生器100以哪个角度安装,都能确保吸气孔115一直与外部气源连通。Further, the outer wall of the generator body 110 is provided with an annular groove 114, and the suction hole 115 is disposed in the groove 114. When the micro-nano bubble generator 100 is mounted to another device, the provision of the recess 114 ensures that the suction aperture 115 is always in communication with the external source of gas regardless of the angle at which the micro-nano bubble generator 100 is mounted.
更进一步地,吸气孔115可以根据实际需要设置多处。Further, the air suction holes 115 can be provided in multiple places according to actual needs.
参照图2、图3,
剪切滤出部140可以包括两层滤网,沿由进液口至出液口的方向(即箭头500的方向)依次设置有第一滤网141、分隔环142、第二滤网143、固定件144,液体在第一滤网141、第二滤网143之间形成缓冲空间,产生紊流以在消除大气泡同时增加液体的含气量。另外,可以根据实际需要设置多层滤网。Referring to Figures 2 and 3,
The shearing filter portion 140 may include a two-layer screen, and a first filter screen 141, a partition ring 142, a second filter screen 143, and a second filter screen 141 are disposed in the direction from the liquid inlet to the liquid outlet (ie, the direction of the arrow 500). The fixing member 144, the liquid forms a buffer space between the first screen 141 and the second screen 143, generates turbulence to increase the gas content of the liquid while eliminating large bubbles. In addition, a multi-layer filter can be provided according to actual needs.
为了在剪切滤出部140尽可能产生强烈紊流的同时,尽可能降低背压,剪切滤出部140优选地可以设置多层滤网,各层滤网使用上述用于隔开各层滤网的分隔环142隔开,以形成2-8处上述的缓冲空间。In order to reduce the back pressure as much as possible while the shear filter 140 is as strong as possible, the shear filter 140 may preferably be provided with a multi-layer screen, each layer being used to separate the layers. The separator rings 142 of the screen are spaced apart to form the above-described buffer space at 2-8.
进一步地,滤网为疏水金属网,其目数为200#-8000#。在实际的组合中,如使用两层滤网时,可以设置第一滤网141的目数为200#-800#,第二滤网的143的目数为800#-8000#,以实现对气液混合后的液体更好地剪切滤出。Further, the filter mesh is a hydrophobic metal mesh having a mesh number of 200#-8000#. In an actual combination, if a two-layer filter is used, the mesh number of the first filter 141 may be set to 200#-800#, and the mesh number of 143 of the second filter mesh may be 800#-8000#, to achieve The liquid-liquid mixed liquid is better sheared and filtered out.
更进一步地,在其他多层滤网的组合中,可以设置为各层滤网沿由进液口至出液口的方向(即箭头500的方向),各滤网的目数至少相同或者逐层增加,以实现在产生的紊流中剪切大气泡、增加液体的含气量、控制微纳米气泡的大小的顺序控制。Further, in the combination of other multi-layer screens, it may be arranged such that the screens of the respective layers are in the direction from the liquid inlet to the liquid outlet (ie, the direction of the arrow 500), and the meshes of the screens are at least the same or The layer is increased to achieve sequential control of shearing large bubbles in the generated turbulent flow, increasing the gas content of the liquid, and controlling the size of the micro-nano bubbles.
关于缓冲空间的层数、不同滤网的组合对产生的微纳米气泡的影响,本发明人进行过大量的除污实验,由于微纳米气泡数量越大、气泡越小,其除污能力越强,因为,通过观察具有不同缓冲空间的层数、不同滤网的组合的微纳米气泡发生器所剪切滤出的水的实际除污能力,可以直接反向推断出其产生的微纳米气泡的效果。参照下表Regarding the influence of the number of layers of the buffer space and the combination of different screens on the generated micro-nano bubbles, the inventors conducted a large number of decontamination experiments, and the larger the number of micro-nano bubbles, the smaller the bubbles, the stronger the decontamination ability. Because, by observing the actual decontamination ability of the water filtered by the micro-nano bubble generator with different number of layers of different buffer spaces and different filter screens, the micro-nano bubbles generated by the micro-nano bubbles can be directly inferred. effect.
