Description

Technical field: [0001] The invention relates to the field of chemical transfer process equipment, in particular to an integrated device with multiple mixing and heat transfer methods, including stirring mixing, ultrasonic mixing, impinging flow mixing, supergravity mixing, microwave heating, partition heat exchange and direct heat exchange hot. Background technique: [0002] Traditional stirring reaction equipment is a device widely used in mixing and chemical reactions in industry. Most of them operate intermittently and can be applied to momentum transfer, heat transfer and mass transfer processes. Stirred reaction equipment is greatly affected by the volume of the equipment. The interphase mass transfer and heat transfer process inside the reaction equipment is difficult to achieve the desired effect in a very short time, especially the chemical reaction process controlled by microscopic mixing and strong absorption and exotherm. The chemical reaction process is particu...

AI Technical Summary

Problems solved by technology

If the stirring cannot adjust the heat transfer or mass transfer in time, it will lead to the loss of control of the temperature field and concentration field in the system, which is a serious danger to the chemical reaction process and reaction equipment.

Hypergravity equipment and impinging flow equipment are ideal reaction equipment that can achieve rapid mixing, but their disadvantages are that the material residence time is short, which is suitable for rapid mixing and reaction processes

However, due to the dissipation and loss of ultrasonic waves and microwaves in the medium, it is difficult for ultrasonic waves and microwaves to effectively control the heat transfer and mass transfer processes inside large-volume reaction equipment. In industry, they are only used as a means of auxiliary mixing and heating. There are great limitations in the application of technology

For complex mixing processes or chemical reaction processes, the mixing requirements of different reaction stages are also different, and a single mixing method is difficult to meet, so it is necessary to increase the number of corresponding equipment, resulting in a longer process flow and increased energy consumption
