Description

Technical Field

[0001] This utility model relates to the field of aeration technology, and in particular to an HBD micro-nano air aeration generator. Background Technology

[0002] In the biochemical processes of wastewater treatment, the aeration system is the core component, and its efficiency directly determines oxygen transfer efficiency, energy consumption, and operating costs.

[0003] Currently widely used traditional diaphragm-type microporous aerators have several inherent defects: their diaphragm material is prone to aging, scaling, and clogging during long-term operation, leading to uneven aeration; the diaphragm pores may not effectively rebound under water pressure, causing sludge backflow, which not only exacerbates clogging but also causes pressure buildup in the air supply pipeline, increasing the blower load and energy consumption, and shortening the blower's lifespan. Especially when dealing with fluctuations in water quality, these aerators are slow to respond, lack sufficient precision in dissolved oxygen control, and their diaphragms require regular replacement, resulting in high maintenance costs. Overall, their energy efficiency ratio needs improvement.

[0004] To overcome the aforementioned shortcomings, the industry has explored aeration technology based on the Venturi principle, aiming to achieve gas-liquid mixing through the fluid's own power. However, some existing Venturi aeration devices still suffer from problems such as complex structure, easy clogging of internal flow channels, low efficiency of negative pressure ejection, and insufficient uniformity and fineness of the generated bubbles.

[0005] To address this, we propose an HBD micro / nano air exposure generator. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an HBD micro / nano air exposure generator.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an HBD micro-nano air aeration generator, including an aeration mechanism and a cutter. The aeration mechanism includes several vertically arranged connecting sleeves, and adjacent connecting sleeves are sealed by threaded connections. Several connecting rods are uniformly fixedly connected to the outer surface of the top single connecting sleeve, and several air distribution rods are fixedly interconnected on the outer surface of the remaining multiple connecting sleeves.

[0008] The ends of several connecting rods and the ends of several air distribution rods in the same layer are all fixedly connected to a Venturi assembly;

[0009] Each of the Venturi components includes a frame, with a plurality of reinforcing columns uniformly and fixedly connected to the inner surface of the frame, and inclined guide plates fixedly sleeved on the outer surface of each of the reinforcing columns. Adjacent guide plates are fixedly connected to each other, and the guide plates are fixedly connected to the top of the frame. Connecting rods and air distribution rods are fixedly connected to adjacent guide plates respectively.

[0010] Each of the aforementioned reinforcing columns has a through hole extending to the bottom at its top, and the air distribution rod communicates with the adjacent through hole.

[0011] The slitter includes a connecting seat, which is threadedly and sealed to the top of the top connecting sleeve. An inverted conical baffle is fixedly sleeved on the outer surface of the connecting seat, and multiple slitting blocks are uniformly and fixedly connected to the bottom of the inverted conical baffle.

[0012] Furthermore, several air distribution holes are provided at the top of each of the aforementioned air distribution rods.

[0013] Furthermore, the outer surface of each of the reinforcing columns connected to the air distribution rod is provided with a side hole that extends into the interior.

[0014] Furthermore, the outer surface of the connecting seat is uniformly and fixedly connected with a plurality of reinforcing ribs, and the reinforcing ribs are fixedly connected to the inner surface of the inverted cone baffle.

[0015] Furthermore, the inner surface of the inverted cone baffle is uniformly provided with three circular holes that extend to the bottom.

[0016] Furthermore, the frame, reinforcing columns, and guide plates are designed as a single unit.

[0017] The beneficial effects of this utility model are:

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-4 As shown, an HBD micro-nano air aeration generator is disclosed, including an aeration mechanism and a cutter 1. The aeration mechanism includes several vertically arranged connecting sleeves 5, and adjacent connecting sleeves 5 are connected by sealed threads. The modular threaded connection structure enables flexible adjustment of the overall height, which can adapt to different water depth process requirements.

[0028] Several connecting rods 3 are uniformly fixedly connected to the outer surface of the top single connecting sleeve 5, and several air distribution rods 4 are fixedly interconnected on the outer surface of the remaining multiple connecting sleeves 5. Several air distribution holes 41 are opened at the top of the air distribution rods 4 to achieve preliminary aeration and prevent sludge from depositing and clogging inside the air distribution rods 4.

[0029] The ends of several connecting rods 3 and the ends of several air distribution rods 4 in the same layer are all fixedly connected to a Venturi assembly 2. Each Venturi assembly 2 includes a frame 25. Several reinforcing columns 21 are uniformly fixedly connected to the inner surface of the frame 25. Inclined guide plates 22 are fixedly sleeved on the outer surface of each reinforcing column 21. Adjacent guide plates 22 are fixedly connected to each other. The guide plates 22 are fixedly connected to the top of the frame 25. The connecting rods 3 and air distribution rods 4 are fixedly connected to adjacent guide plates 22. The frame 25, reinforcing columns 21 and guide plates 22 are designed as a single unit. The single-unit Venturi structure is sturdy and durable and can generate a high-efficiency gas-liquid mixing effect in a long-term stable manner.

[0030] The top of several reinforcing columns 21 is provided with through holes 23 extending to the bottom, and the air distribution rod 4 communicates with the adjacent through holes 23. The outer surface of several reinforcing columns 21 that communicate with the air distribution rod 4 is provided with side holes 24 extending to the interior.

[0031] The slitter 1 includes a connecting seat 12, which is threadedly sealed to the top of the top connecting sleeve 5. An inverted conical baffle 14 is fixedly sleeved on the outer surface of the connecting seat 12. Multiple slitting blocks 15 are uniformly fixedly connected to the bottom of the inverted conical baffle 14. Multiple reinforcing ribs 11 are uniformly fixedly connected to the outer surface of the connecting seat 12, and the reinforcing ribs 11 are fixedly connected to the inner surface of the inverted conical baffle 14. Three circular holes 13 extending to the bottom are uniformly opened on the inner surface of the inverted conical baffle 14. The slitter 1 uses the slitting blocks 15 to ultimately break up the rising bubbles. Combined with the guiding effect of the inverted conical baffle 14, the micro-nano bubbles are more evenly distributed in the water. The circular holes 13 effectively balance the internal water flow pressure.

[0032] Working principle: Compressed air is introduced from the bottom, first entering the lowest connecting sleeve 5, and then the air is stably delivered from bottom to top through the central vertical pipe formed by multiple connecting sleeves 5 connected in sequence by sealing threads.

[0033] During the air rise process, the air distribution rods 4 located on each layer are connected to the air through the connecting sleeve 5. The air distribution rods 4 act as conveying pipes, leading the air out horizontally and radially, while the air distribution holes 41 at the top can perform preliminary air distribution.

[0034] Air enters the internal channel of the Venturi assembly 2 (i.e., the central space enclosed by the polygonal frame 25) and flows upward. When the airflow passes through the narrow area formed by several guide plates 22, the flow velocity increases, generating the Venturi effect and forming a local negative pressure. This negative pressure forcefully draws in the surrounding water through the gaps between the guide plates 22.

[0035] Air and water undergo initial forced mixing inside and above the Venturi assembly 2, and the gas is initially sheared into bubbles. During this process, the reinforcing column 21 ensures the structural strength of the guide plate 22 and the polygonal frame 25 to maintain a stable flow field.

[0036] The mixed gas-liquid two-phase flow continues to rise and directly impacts the cutting block 15 at the bottom of the cutter 1. The cutting block 15 performs final, forced physical shearing on the bubble group, breaking the bubbles to the micro-nano level. Finally, a large number of micro-nano bubbles diffuse evenly in all directions under the guidance of the inverted cone baffle 14 and enter the water body to be treated.

[0037] The circular holes 13 on the inverted cone baffle 14 help balance the water flow and reduce resistance.
