The speed of the motor needs to be adjusted through the reducer to adjust the stirring speed, and then the stirring shaft and the stirring blades are driven to rotate through the coupling. This mechanical stirring and mixing device has a series of defects such as bulky, high cost, high energy consumption, significant amplification effect, high installation space and poor mixing effect.

The air-lift tower mixer is a new generation of high-efficiency and energy-saving equipment with a circular guide tube inside or outside the tube to generate internal circulation or external circulation to promote the full circulation and mixing of gas and liquid. It makes good use of the lift of the gas. The density difference in the inner and outer circulation zones enables effective axial mixing and rapid circulation without agitation. Its internal guide tube separates the ascending and descending fluids well, but this tower device with a built-in guide tube has a complex structure, narrow space between the inner wall of the tower and the outer wall of the guide tube, and is prone to fouling and difficult to clean and repair. , may cause a dead zone, require a large height-to-diameter ratio, and the liquid level is lower than the guide tube, which will lead to the inability to circulate and must maintain the minimum liquid level, which is not suitable for solid-liquid systems, etc., which need further improvement.

The swirling flow mixing type high-efficiency new general-purpose mixing device of the inner guide tube. The device greatly simplifies the structure of the existing mechanical stirring and air-lift tower devices, overcomes the shortcomings of traditional mixing equipment such as complexity, high cost, and easy fouling, and creates the use of radial, axial and material jets and interface dispersion between multi-phase systems. It is a new type of high-efficiency and energy-saving equipment that strengthens the mixing process by various means. This material dynamic mixing mode, which is jointly promoted by gas and liquid, can significantly improve the amplification effect, completely replace the traditional mechanical stirring mixer, and optimize the traditional gas lift. Tower mixers and swirl mixers can achieve good mixing effects in kettles and tower containers. The invention can improve the mixing and mass transfer of materials between heterogeneous systems, especially in biological fermentation and sewage treatment, which can improve the oxygenation effect and greatly reduce the energy consumption of gas explosion.

When measuring the relationship between dissolved oxygen and time in the new device, put 1500L of clean water into a reaction vessel with a diameter of 120cm and a height of 150cm, using 2 fan-shaped nozzles and 2 wide-angle nozzles, with a liquid flow rate of 6m ³ /h and an air flow rate of 3m ³ /h Next, the result is shown in Figure 13.

Apparently, the above examples are only examples for clear description, rather than limiting the implementation. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. It is not necessary and impossible to exhaustively list all the implementation manners here. And the obvious changes or changes derived therefrom are still within the scope of protection of the present invention.
