Device for heat and mass transfer and reaction of high-viscosity materials

Abstract

The invention discloses a device for heat and mass transfer and a reaction of high-viscosity materials, belonging to the field of material heat exchange equipment and reactors. The mass transfer device for the high-viscosity materials comprises magnetic force generators which can generate a magnetic force field for heating, a jacket shell which is used for containing materials and installing the magnetic force generators, a dispersing assembly which is used for transferring the materials, and a hollow shaft which is used for driving the dispersing assembly to rotate, wherein the magnetic forcegenerators are located inside or outside the shell, and the magnetic force generators are oppositely installed in an up-down direction or a left-right direction. The device of the invention has the beneficial effects of high heating power, high heat transfer efficiency, shortened material retention time, uniform heating, safe operation performance and great reduction in material coking.

Description

technical field [0001] The invention relates to the field of heat and mass transfer and reaction equipment for high-viscosity materials, in particular to a device for strengthening heat and mass transfer and reaction of high-viscosity materials through the action of a magnetic force field. Background technique [0002] The high-viscosity materials used in industrial production processes such as chemical industry, medicine and food processing today have the characteristics of high viscosity, poor fluidity and large changes in physical properties with temperature (viscosity-temperature characteristics), making ordinary evaporators, heat exchangers and reactors When dealing with high-viscosity materials, there are generally problems such as low thermal efficiency, long residence time, and large equipment; therefore, some evaporators, heat exchangers and reactors for high-viscosity materials have been continuously developed. Suppliers include: B1awknox, Chemtron, Contro and Plan...

Problems solved by technology

[0002] The high-viscosity materials used in industrial production processes such as chemical industry, medicine and food processing today have the characteristics of high viscosity, poor fluidity and large changes in physical properties with temperature (viscosity-temperature characteristics), making ordinary evaporators, heat exchangers and reactors When dealing with high-viscosity materials, there are generally problems such as low thermal efficiency, long residence time, and large equipment; therefore, some evaporators, heat exchangers and reactors for high-viscosity materials have been continuously developed. Suppliers include: B1awknox, Chemtron, Contro and Plandler in the United States, Luwa in Switzerland, Hitachi, Nissho Machinery, Sakura Manufacturing, Sanyo Machinery in Japan, Balfour in the United Kingdom, BUSS Technology in Germany, etc.

Although many types of equipment have been put into production, the devices and processes involved in the prior art have the disadvantages of small effective heat transfer area of ​​the evaporator, low frequency of material surface renewal, too small material evaporation or vaporization interface, and slow evaporation rate. Technical defects such as slow speed and low capacity per unit volume of equipment (the existing equipment can handle a narrow range of elasticity, which means that it cannot be applied to both low-viscosity materials and high-viscosity materials); in addition, the existing It is difficult for advanced equipment and technology to handle ultra-viscous materials over a million centipoise
