Description

A shipborne mobile nano-aeration generator

technical field

The invention relates to a nano-aeration generating device, in particular to a ship-borne mobile nano-aeration generating device.

Background technique

Compared with traditional large bubbles, micro-nano bubbles have smaller volume, longer stay in water, faster oxygenation rate, and more significant oxygenation effect. The surface is negatively charged and has strong oxidizing ability, which can effectively degrade The pollutants in the water have a good effect on the emergency treatment of the polluted water body and the maintenance in the later period. Therefore, the development of micro-nano bubble generating devices is an inevitable trend in the market. The core structure of the invention, that is, the principle of the nano-bubble production unit, is based on the pressurized dissolved air method, and the unique rotary cutting structure + Venturi structure design is adopted at the aeration head, which can rotary cut, collide, and break the bubble water for many times, and realizes more The effect of stable micro-nano bubble preparation. The nano-aeration unit is combined with the hull, and the aeration heads of the nano-aeration equipment are evenly distributed on both sides of the hull. During the running process of the hull, the nano-aeration equipment is operated at the same time, so that the nano-bubbles spread with the ship, and the nano-bubble can be dispersed. It has a wider range of services, a larger water area, and high mobility. Before the present invention and the method are made, other methods for generating micro-nano bubbles at home and abroad include water temperature difference method, electric field method, microwave method, Venturi jet method, etc. The preparation of micro-nano bubbles can produce nano-bubbles, but the water area they serve is small, and the generated nano-bubbles are not sufficiently diffused outward. reduce.

Among them, the particle size of the bubbles prepared by the venturi jet method cannot reach the nano-scale, and the jet is mainly used in the push-flow aeration stage of the sewage plant, and the application field is very limited; the water temperature difference method cannot accurately control the temperature difference of the water temperature, In addition, the number of prepared micro-nano bubbles is small. This device has many working parts, complex coordination and high energy consumption. Combining it with a mobile ship requires high requirements on the size of the hull and the equipment on board, and the maintenance costs in the later period are also high. High; the microbubbles generated by the electric field method have the disadvantages of less existence, electrode consumption, and high energy consumption. Combined with the hull to form a mobile aeration equipment, the power supply system of the hull is very demanding, and the later operation and maintenance costs are high. Therefore, The electric field method nano-aeration equipment is rarely used in the engineering field.

The pressurized dissolved air micro-nano bubble generating device has important application potential due to its advantages of "compact structure, high controllability, and small bubbles produced". However, the amount of bubbles produced by the traditional pressurized dissolved air aeration device It is too small, and the generated micro-nano bubbles diffuse unevenly and insufficiently when applied to rivers and lakes. At the same time, the pressure required for the pressurized dissolved gas process is high, resulting in high energy consumption. Therefore, the present invention proposes a The multi-stage rotary cutting and crushing type micro-nano bubble generation method and generation device based on the principle of dissolved air, and with the corresponding specifications of the hull, the aeration equipment combines mobility and high efficiency, and the device itself carries a special aeration head , which can make the preparation of micro-nano bubbles easier, and at the same time reduce the pressure and energy consumption required for gas-liquid mixing, that is, pressurized dissolved gas. This is an inevitable requirement for the wide application of micro-nano bubble generation technology in river and lake water treatment.

To sum up, the present invention designs a shipborne mobile nano-aeration generating device.
