Abstract

The invention provides an air-lift high-efficiency circulation mixing device for swirling flow without an inner guide cylinder, which uses a guide member including a stator and a rotor, the rotor is provided with a liquid nozzle, the liquid nozzle is connected with the liquid guide pipe, and the liquid The guide pipe is arranged inside the rotor and the stator, and a gas outlet is provided on the guide part, and the gas outlet communicates with the gas guide pipe, and a mixing device including the preparation of the guide part is provided. The device uses circulating liquid to push the rotary nozzle to rotate and spray liquid materials to strengthen the direct mixing of radial materials, and at the same time introduce reaction or heating or working gas near the nozzle, and fully disperse the liquid materials and gases with the help of the liquid flow ejected by rotation, and at the same time use the gas lift to generate upward Circulation, enhanced axial material mixing, overcomes the shortcomings of the traditional guide tube mixing device, which is complex in structure, easy to scale, and difficult to remove the outer interlayer.

Description

technical field [0001] The invention provides a novel swirling flow type high-efficiency mixing device which can effectively improve mixing by adjusting the gas-liquid flow rate. Background technique [0002] In the production process of chemical, pharmaceutical, water treatment, metallurgical and food industries, mixing is often involved. In traditional mixing devices, electric motors and transmissions are needed to drive huge stirring paddles. The stirring motors are generally installed in the kettle. The top of the body is usually arranged vertically. 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. [0003] The air-lift tower mixer is a...
