Abstract
The invention discloses a super-gravity rotating packed bed device. According to the device, a super-gravity rotating packed bed made of 304 stainless steel is selected, and the problems of equipment corrosion and impurities mixed into reaction products under acid-base reaction and other conditions are effectively avoided. According to the device, sealing bearings are adopted for fixing the two ends of the rotating packed bed, so that firstly, it is ensured that a gas phase in the rotating packed bed completely flows inside a packing layer and sufficiently reacts with a liquid phase, and the phenomenon that the equipment performance is lowered due to the fact that an incomplete gas liquid reaction is caused by gas leakage is avoided; secondly, it is ensured that in the rotating packed bed operation process, central symmetry motion is performed around the axial direction, and the dynamic balance is achieved; thirdly, it is ensured that the two ends of the rotating packed bed are fixed in the high-speed operation process, and the safety performance is improved. The device is further provided with a gas buffer chamber, and the problems that outlet gas caused is not uniform after a gas liquid reaction and equipment is damaged by humid gas are effectively avoided.
Description
Technical field
The present invention relates to a kind of high gravity rotating packed bed device.Belong to field of chemical equipment.
Background technology
So-called hypergravity refers to than terrestrial gravitation acceleration (9. 8 m/s2) much bigger in the environment of suffered by material
The power arrived.The science of the physical and chemical changes process under research Elevated Gravity is referred to as hypergravity science, utilizes hypergravity section
The application technology learning principle and formulate is referred to as high-gravity technology.On earth, it is achieved the short-cut method of Elevated Gravity is to pass through
Rotate and produce centrifugal force and simulated implementation.So slewing is referred to as hypergravity machine, is also called RPB.
RPB (Rotating Packed Bed) is that the one grown up the eighties in 20th century is emerging, efficient
Gas-liquid mass transfer (contact) equipment；Its operation principle is with under the centrifugal action of hundreds of to thousand times gravity (hypergravity) at packed bed medium ring, liquid
Forming liquid film at filling surface, liquid film quickly moves to outside circulation, and thickness of liquid film strongly reduces, and wet support area increases, phase
Interfacial area increase result in and obtained great strengthening by the facies-controlled mass transfer of liquid, heat transfer and course of reaction.Height of transfer unit
Reduce 1 ~ 2 order of magnitude, and demonstrate many advantages not available for legacy equipment.So that huge tower becomes high
The degree overweight machine less than 2 meters.Therefore, high-gravity technology is considered as a breakthrough skill of strengthening mass transfer and heterogeneous reaction process
Art, is described as " transistor " of chemical industry.
At home, 1988, Beijing University of Chemical Technology cooperated, by Glitsch with U.S. Case Westem Reserve university
Company provides hypergravity main frame, establishes a set of experimental provision in Beijing University of Chemical Technology, proceeds by the basis of high-gravity technology
Study and for application technical researches such as oil-field flooding deoxidation, culture propagations.Nineteen ninety, establish me in Beijing University of Chemical Technology
First high gravity technology research center of state, Ministry of Education's hypergravity Engineering Research Center is set up in calendar year 2001 upgrading.Hereafter, Zhejiang
Jiang great Xue, Northcentral University, University Of Tianjin, Wuhan Institute of Chemical Technology, University Of Xiangtan the most also expand the research of high-gravity technology.Warp
After research and development for many years, achieve a series of achievement in research leading in the world.
High gravity rotating packed bed is strengthening multiphase flow transmission and the new technique of course of reaction, since coming out, at home
Paid attention to widely outward, due to its broad applicability and have that the volume that legacy equipment do not has is little, lightweight, energy
Consume operating low, easy, easy-maintaining, safe and reliable, flexible and be suitable for the advantages such as environment so that high-gravity technology is the most extensive
It is applied to: separate the field such as rectification, preparation nano material, environment-industry, biochemical industry, crop breeding.
