Description

Rotary self-sucking dish-shaped nano-bubble generator

Background technique

In recent years, with the rapid social and economic development, the contradiction between the increasing level of economic development and the water environment and water ecology has intensified; the problem of water environment pollution is particularly prominent, which is manifested in the slow renewal rate of rivers and lakes and the acceptance of domestic sewage The large amount of industrial wastewater caused serious pollution of rivers and lakes. The population of the eastern region of China increased sharply, accelerating the accumulation of organic matter and nutrients in rivers and lakes, and aggravated the degree of eutrophication of lakes. However, the development scale of today's environmental protection technology industry is even lower, the period for research and application of new environmental protection technology is long, the technological innovation capacity is weak, the existing related aeration devices have large bubbles, low dissolved oxygen rate, high energy consumption, etc. Many shortcomings, mixed fish and dragons, and the treatment effect on black and odorous waters are also uneven.

In addition to the utility model, domestic methods for generating micro-nano bubbles include pressure-dissolved gas release method, venturi jet method and other methods. The pressurized dissolved gas release method is to change the gas pressure to change the solubility of the gas in the dissolved gas irrigation, and then restore the pressure to precipitate the gas in the form of micro-nano bubbles. The method has the disadvantages of high micro energy and small application range. The venturi jet method uses a variety of shear forces to smash the gas to form micro-nano bubbles. Venturi jet type micro-nano bubble generating device has the advantages of "compact structure, not easy to block, large flux" and so on; but the traditional single-tube Venturi jet device cannot form a 360 ° omnidirectional jet due to a single jet direction. When the bubbles are applied in rivers and lakes, the diffusion is uneven and insufficient, and the jet consumption is high. Therefore, the utility model proposes a rotary self-suction dish-shaped nano-bubble generator.

The cylindrical shell 7 is provided with a plurality of convex blades 12, and the cylindrical shell 7 is sheathed with a self-priming dish-shaped nano-bubble generating device 4 The self-priming dish-shaped nano-bubble generating device 4 includes a dish-shaped shrink disk 11, a throat cavity 8, a dish-shaped diffusion disk 5, an upper disk 3, and a lower disk 6, a small head end of the dish-shaped shrink disk 11 and a throat cavity. 8 connection, laryngeal cavity 8 is connected to the small head end of the dish-shaped diffusion plate 5, the dish-shaped shrink disk 11 is externally sleeved with an upper disk 3, the dish-shaped diffusion disk 5 is sheathed with a lower disk 6, and is self-priming The upper disc 3 of the dish-shaped nano-bubble generating device 4 is provided with vent holes. The dish-shaped diffusion disc 5, the throat cavity 8 and the dish-shaped diffusion disc 5 rotate a dish-shaped space structure around the central axis 2.

The upper disk 3, the disk-shaped shrink disk 11, the throat cavity 8 and the disk-shaped diffusion disk 5 are connected to the lower disk 6 to form a fluid channel. The disk-shaped diffusion disk 5, the throat 8 and the disk-shaped diffusion disk 5 rotate around the central axis 2. The disc-shaped space structure is connected to the upper disc 3, the disc-shaped shrink disc 11, the throat cavity 8 and the disc-shaped diffuser disc 5 and the lower disc 6 to form a fluid channel, which communicates through the suction hole 13, and the motor 1 and the upper disc 3 The bolts 9 are connected to each other.

Sheet 10 is connected.

Specifically: A rotary self-suction dish-shaped nano-bubble generating device. When in use, the motor 1 is first turned on. The motor 1 drives the blades 12 of the cylindrical shell 7 to rotate at high speed. The liquid is thrown out of the cylindrical shell 7 by the centrifugal force. Negative pressure is formed at the center of 12, and the self-priming liquid fills the cylindrical shell 7. The liquid rotates at high speed under the action of centrifugal force, and the high-speed rotating liquid gradually expands to the disc-shaped shrink disk 11 of the rotary self-priming disc-shaped nano-bubble generating device 4. As the cross section of the butterfly-shaped shrink disk 11 gradually decreases, the pressure of the compressed air increases, and the flow velocity also increases, resulting in a "vacuum" zone formed at the throat 8 of the self-priming butterfly nano-bubble generator 4 The "vacuum" zone has a certain adsorption effect, which drives the liquid to self-inhale to the larynx cavity. At the same time, the gas inhales air or pure oxygen from the suction port 13 to the larynx cavity. The gas and liquid are mixed in the larynx cavity. A high-pressure, high-speed, uniform fluid is formed, and the fluid releases small cavitation bubbles in the dish-shaped diffusion plate 5 of the self-absorbed butterfly nano-bubble generating device 4. When the cavitation bubbles collapse, the gas contained therein will shrink into Supermicro Bubbles, and cavitation bubbles collapse due to the release of high excitation energy from the water flow will be more ultrafine bubbles, thereby forming gas bubbles nanometers.
