Description
Technical field
The present invention relates to supergravity technical field.It is high-gravity rotating bed more particularly, to a kind of block-resistant type and contain the high-gravity rotating bed system and device of the block-resistant type and application.
Background technology
High-gravity technology is a kind of typical chemical process reinforcement technique, it is a kind of preferable reinforcement technique of the multinomial fast reaction process for being applicable to and being strengthened to interphase mass transfer, heat transfer and molecular mixing, and miniaturization or even miniaturization for chemical process have great importance.
The Core equipment of high-gravity technology is high-gravity rotating bed, is that the centrifugal force simulation Elevated Gravity produced using rotation is transmitted and course of reaction to strengthen, and transmission and course of reaction efficiency can be significantly increased, and is reduced significantly the volume of reaction and separator.Revolving bed device mainly includes the rotor of closed housing and rotation.Fluid under centrifugal force field environment, in the high-gravity rotating bed interior surface area for being torn into tiny drop, brin or liquid film etc., producing substantial amounts of quick renewal, so as to strengthen mass transfer and mixed process significantly.With to high-gravity rotating bed further investigation, it was found that in a smaller area of rotor inner edge (packing volume is about the 10% of cumulative volume in the region), because liquid is vertical with the direction of rotation of rotor inner edge through the direction that liquid distribution trough sprays into rotor inner edge, the rotor that penetrating liquid is rotated consumingly tears, crushes, and produce substantial amounts of new surface, its mass transfer and mixed performance are optimal, and this region is referred to as end effect area by researcher.By comparison, filler cumulative volume is accounted for be about in 90% body region (rotor region removes the part in end effect area), filler to mass transfer or the contribution Zhi Zhan end effects area of mixing 1/5~1/3.
Generally, high-gravity rotating bed interior, rotor loads or is filled with structured packing or wire packing.For some gas-liquids, liquid liquid or gas-liquid-solid system, if reaction produces solid, it is easy to block the filler in rotor, has a strong impact on the normal operation of revolving bed；Moreover, the solia particle for substituting into revolving bed from outside can also block the filler in rotor, dust, particulate matter such as in flue gas.
In the industrial production, some liquid liquid, gas-liquid, gas-liquid-solid reaction can generate solid and produce precipitation, and when such as preparing nano barium sulfate material, barium sulfate is exactly a kind of common crystalline precipitation.Solute is separated out from solution, can be divided into nucleus generation (nucleation) and two stages of crystal growth.The generation of nucleus also has three kinds of forms：Primary homogeneous nucleation, primary nonhomogen-ous nucleation and secondary nucleation.Under high degree of supersaturation, solution spontaneously generates the process of nucleus, is primary nucleation；Solution generates the process of nucleus under the induction of exotic (micronic dust such as in air), is primary nonhomogen-ous nucleation；And in the solution containing solute crystals nucleation process, be secondary nucleation, occur under the induction of produced tiny crystal grains when it is between crystal and crystal or crystal and other solids (wall, agitator etc.) are collided.The dynamics of precipitated products and distribution, depend primarily on nucleus generating rate (the nucleus number produced in unit volume solution in the unit interval), crystal growth rate (incrementss of crystal linear dimension in the unit interval) and crystal mean residence time in the reactor.Three kinds of nucleation modes can all occur in rotary drill reactor, and for general wire packing or structured packing, its internal void is smaller, be easier to collide between the nucleus of generation and between nucleus and wire packing, secondary nucleation；Packing layer is thicker simultaneously, and the sufficient time is provided to crystal growth, and nucleus fast-growth is larger crystal, blocks filler.
And the waste gas for being produced in the production processes such as boiler, cement, building materials, chemical industry and petrochemical industry, using the dirt in high-gravity technology captured gas, mist, to reach the purpose of purification gas, it can replace conventional scrubbing tower, electric cleaner, electrostatic precipitator etc..But, for the revolving bed of general wire packing, its silk screen space is smaller, closeer, for the larger particles in waste gas, easily sticks on wire packing, and wire packing is resulted in blockage；Simultaneously because gas-liquid counter current, from filler outside into rotor packing area, the gas concentration on the outside of packing area is high, and dust content is more, and strength of fluid is small, and the suction-operated to dust is small, and particulate matter is bonded in also certain influence factor on wire packing for gas；Again, liquid from rotor internal cavity jet flow and go out, during to rotor LHA, due to the resistance of silk screen layer by layer, liquid reduces with the relative velocity of silk screen, and souring weakens, and is difficult to wash away the solid particle being bonded on the outside of wire packing.
Therefore, on the premise of the high-gravity rotating bed strong mass transfer ability in end effect area is retained, improve rotor subject plot structure and maintain mass transfer ability suitable therewith, the efficacy effect anti-blocking to reach revolving bed is significant.
