Transfer reaction device and method for high-viscosity material

Abstract

Relating to the field of material transfer equipment and reactors, the invention discloses a transfer and reaction device of a high-viscosity material. The transfer and reaction device comprises a jacket shell, a hollow shaft assembly and a dispersion assembly. The dispersion assembly rotates around the hollow shaft assembly in the shell, and is composed of a plurality of heat exchange pipe networks. The invention also provides a mass transfer method of a high-viscosity material. The heat exchange pipe networks with a high specific surface area rotate in an accommodating chamber holding the high-viscosity material, a heat conduction medium in the heat exchange pipe networks are distributed in the heat exchange pipe networks in an accelerated mode under the action of a centrifugal force, and ducts of the heat exchange pipe networks are communicated with an outer cooling system; and the high-viscosity material is thrown from the inner side of the dispersion assembly to the outer side through the rotary heat exchange pipe networks under the action of centrifugal force. The device and method provided by the invention have the beneficial effects of: increasing the effective heat transfer area, shortening the material retention time, broadening the elastic range of treated materials, treating super-viscous materials, reducing material coking, increasing the productivity, and increasing the equipment productivity.

Description

technical field [0001] The invention relates to the field of material heat and mass transfer and reactors, in particular to a high-viscosity material transfer and reaction device and method. Background technique [0002] There are many types and styles of evaporators, heat exchangers and reactors used in chemical, pharmaceutical and food processing processes today. Because high-viscosity materials have the characteristics of high viscosity, poor fluidity, and large changes in physical properties with temperature (viscosity-temperature characteristics), ordinary evaporators, heat exchangers and reactors have low thermal efficiency, long residence time, and Due to problems such as huge equipment, some evaporators, heat exchangers and reactors for high-viscosity materials have been continuously developed. Manufacturers include: B1awknox, Chemtron, Contro and Plandler in the United States, Luwa in Switzerland, Hitachi Manufacturing in Japan, Nissho Machinery, Sakura Manufacturi...

AI Technical Summary

Problems solved by technology

However, in the devices and processes involved in the prior art, the effective heat transfer area of ​​the evaporator is small, the surface renewal frequency of the material is too low, the material evaporation or vaporization interface is too small, the evaporation speed is slow, and the production capacity per unit volume of the equipment is low, etc. Technical defects; the existing devices can handle a narrow range of elasticity, which means that they cannot be applied to both low-viscosity materials and high-viscosity materials; in addition, existing devices and technologies are difficult to handle more than one million centipoise super viscous material
