Description
Technical field
The utility model belongs to the technical field of chemical industry, petrochemical industry, environmental protection mass transfer reaction equipment; be specifically related to the rotary packed bed mass transfer of a kind of multistage cross flow and consersion unit; be not only applicable to the mass transport process of the liquid film controlled such as rectifying, absorption, be more suitable for the mass transport process strengthening of gas-film controlled.
Background technology
High-gravity technology is a kind of disruptive technology strengthening multiphase transport and course of reaction grown up the eighties in 20th century, its principle is in cross_flow rotating packed bed (also referred to as hypergravity machine), filler rotor high-speed rotates and forms Elevated Gravity, the filled shearing atomization of liquid, alternate contact area increases, and surface upgrades result in fast and is greatly strengthened by the facies-controlled mass transfer of liquid, heat transfer and course of reaction.Be mainly used in desulfurization, decarburization, dedusting and nano material at present and the aspect such as prepare.
Gas-liquid contact mode in cross_flow rotating packed bed can be divided into adverse current and flow, cross-flow.Rotary packed bed inner rotator conventional is at present monolithic construction, namely the filler in rotor is by single rotating shaft driven rotary, the patent of first high-gravity rotating bed aspect is proposed in 1979 by Imperial Chemical Industries of Britain (ICI), the patent No. is EP0002568, and at home and abroad disclosed patent has also continued this rotor structure substantially successively subsequently.Calendar year 2001, the people such as Sandilya study discovery, the mass transferring in gas phase process of carrying out in rotary packed bed, also low than in packed tower of its mass tranfer coefficient, reason is subject to frictional force effect after gas enters filler, and the Relative sliding speed between filler is very little, and gas phase interface can not get quick renewal, in filler, the phenomenon of liquid distribution inequality can make mass transfer rate reduce further simultaneously.2004, the research of the people such as D P Rao showed, mainly enhance mass transfer in liquid phase process in high-gravity rotating bed, under super gravity field, the use of high-specific surface area filler is its main cause, and gas phase mass transfer coefficient is then suitable with conventional filler tower.2005, Chandra A causes centrifugal acceleration almost not affect gas phase mass transfer coefficient for the rotary packed bed middle gas phase sliding velocity of adverse current too little (2 ~ 3 m/s) of overall filler, propose layer-stepping filler revolving bed (Rotating Packed bed with Split Packing first, SP-RPB), by the packing ring that common rotary packed bed interior unitary rotor filler is divided into some circles mutually nested, this improvement improves gas phase and is rotating the tangential sliding velocity in filler.2006, wait people to have studied the mass-transfer performance of SP-RPB, result shows that the gas phase of this equipment and Liquid volumetric mass transfer improve nearly 2 orders of magnitude than common revolving bed.The people such as Agarwal have done a series of rectifying and absorption experiment with SP-RPB, and result shows that SP-RPB is particularly suitable for strengthening the mass transport process of gas phase drag control.But there are some problems equally in SP-RPB, as: rotor center or little by paracentral position radius of turn, gas is difficult to obtain larger tangential velocity by the High Rotation Speed of filler, and gas phase less turbulence is not enough, and radially skewness, filler utilization rate is lower; Filler uses foam metal to be directly fixed on lower rotary table, not easily changes, and only relies on the mechanical strength of foam metal self during work, is difficult to the occasion being applied to atm number and large liquid measure.
Within 2013, Northcentral University develops a kind of counter-rotating packed bed, number of patent application 201310402589.3, name is called " a kind of flue gas desulfur device and technique ", its main body comprises collection chamber and main chamber, be provided with the top rotary table and lower rotary table that can independently rotate in main chamber, the packing ring on upper and lower rotating disk is nested against one another.This super-gravity device structure can increase the shear stress to fluid, and more Momentum Transfer to internal flow, is promoted the boundary layer separation of gas-liquid by filler, and less turbulence is aggravated, and accelerates gas-liquid interface renewal rate, thus reaches the object of strengthening mass transferring in gas phase; Improve run stability, be more suitable for the occasion of large flux; Collection chamber effectively inhibits to carry secretly and operation is balanced to the impact brought with liquid flooding.Counter-rotating packed bed, to the reverse shear action of gas-liquid, enhances mass transferring in gas phase.But, it still belongs to the gas-liquid counter current way of contact on the whole, this just requires that the interior ring size of packing layer is enough large, radial dimension is just larger comparatively speaking, for the rotor part of high-speed rotation, size increase can bring inconvenience to processing and manufacturing, installation and debugging, and particularly energy consumption and investment also can increase greatly.
It is cross current rotary bed that South China Science & Engineering University develops a kind of multistage atomizing, such as document (Pan Chaoqun, the characteristic of multistage atomizing cross_flow rotating packed bed and application, 2007), air-flow enters revolving bed by the air inlet of revolving bed, absorbing liquid is sprayed on first order donut packing layer from being positioned at the foraminate sparge pipe of revolving bed central zone, forced radially to make aerosol dispersion by powerful centrifugal force, after the atomization of the experience first order, drop is spread across on the donut packing layer of the second level again, experience centrifugal atomizing again, final liquid is fallen under gravity at the bottom of revolving bed along wall and is discharged by discharging tube.Liquid can be carried out multistage atomizing by this device, considerably increase the degree of scatter of liquid phase, because drop Inner eycle is very violent, thus make film mass transfer coefficient in the drop of multistage atomizing revolving bed higher, but it is relatively weak for the mass transport process invigoration effect of gas-film controlled, within 2010, Zhang Yanqing have studied the rotary packed bed mass-transfer performance of double atomization, for alkali liquor absorption SO
2this gas-film controlled process, under similar conditions, its gaseous phase volume mass tranfer coefficient than traditional filler tower height 1 order of magnitude, but lower than common Cross-Flow Rotating Packed Bed.
