Description
Technical field
The present invention relates to supergravity technical fields.More particularly, to a kind of block-resistant type it is high-gravity rotating bed and containing should
The high-gravity rotating bed system and device of block-resistant type and application.
Background technique
High-gravity technology is a kind of typical chemical process reinforcement technique, it be one kind be applicable to interphase mass transfer,
The ideal reinforcement technique for the multinomial fast reaction process that heat transfer and molecular mixing are strengthened, the miniaturization for chemical process are
Have great importance to micromation.
The Core equipment of high-gravity technology, that is, high-gravity rotating bed is the centrifugal force simulation hypergravity ring generated using rotation
Transmitting and reaction process efficiency can be significantly increased to strengthen transmitting and reaction process in border, be reduced significantly and react and separate
The volume of device.Revolving bed device mainly includes the rotor of closed shell and rotation.Fluid is under centrifugal force field environment, super
It is torn into tiny drop, brin or liquid film etc. in gravity revolving bed, the surface area largely quickly updated is generated, thus greatly
It is big to strengthen mass transfer and mixed process.With one to high-gravity rotating bed further investigation, found in close proximity to rotor inner edge compared with
In zonule (packing volume is about the 10% of total volume in the region), since liquid sprays into rotor inner edge through liquid distribution trough
Direction is vertical with the direction of rotation of rotor inner edge, sprays into the rotor that liquid is rotated and consumingly tears, is broken, and generates a large amount of
New surface, mass transfer and mixed performance are optimal, this region is referred to as end effect area by researcher.In contrast, accounting for filler
In the body region (part in rotor region removing end effect area) that total volume is about 90%, filler is to mass transfer or mixed contribution
Account for the 1/5~1/3 of end effect area.
In general, rotor loads or is filled with structured packing or wire packing high-gravity rotating bed interior.For certain gas
Liquid, liquid liquid or gas-liquid-solid system, if reaction generates solid, the filler being easy in blocking rotor seriously affects revolving bed
It operates normally；Moreover, the filler in rotor can be also blocked from the external solia particle for substituting into revolving bed, such as the powder in flue gas
Dirt, particulate matter.
In the industrial production, some liquid liquid, gas-liquid, gas-liquid-solid reaction can generate solid and generate precipitating, such as prepare nano-sulfur
When sour barium material, barium sulfate is exactly a kind of common crystalline precipitation.Solute is precipitated from solution, can be divided into nucleus generate (at
Core) and two stages of crystal growth.The generation of nucleus is also there are three types of form: 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 is in exotic (as greatly
Micronic dust in gas) induction under generate the process of nucleus, for primary nonhomogen-ous nucleation；And in the solution containing solute crystals at
The process of core is secondary nucleation, it is between crystal and crystal or when crystal and other solids (wall, blender etc.) collide
Occur under the induction of generated tiny crystal grains.The dynamics and distribution of precipitated products, depend primarily on nucleus generating rate
(the nucleus number generated in unit volume solution in the unit time), crystal growth rate (crystal linear dimension in the unit time
Incrementss) and crystal mean residence time in the reactor.Three kinds of nucleation modes can all occur in rotary drill reactor,
For general wire packing or structured packing, internal void is smaller, between the nucleus of generation and nucleus and wire packing
Between be easier to collide, secondary nucleation；Packing layer is thicker simultaneously, provides sufficient time, the fast fast-growing of nucleus to crystal growth
A length of larger crystal blocks filler.
And the exhaust gas for being generated in the production processes such as boiler, cement, building materials, chemical industry and petrochemical industry, utilization is overweight
Dirt, mist in power technology captured gas, to achieve the purpose that purification gas, it can replace conventional scrubbing tower, electric precipitator,
Electrostatic precipitator etc..But for the revolving bed of general wire packing, silk screen gap is smaller, closeer, for larger in exhaust gas
Particle easily sticks on wire packing, results in blockage to wire packing；Simultaneously because gas-liquid counter current, gas on the outside of filler into
Entering 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 it is small to the suction-operated of dust,
Being bonded on wire packing also to particulate matter has certain influence factor；Again, liquid from rotor internal cavity jet flow and go out, to turn
When sub- outside area, due to the resistance of silk screen layer by layer, the relative velocity of liquid and silk screen reduces, and souring weakens, and is not easy to wash away
Fall to be bonded in the solid particle on the outside of wire packing.
Therefore, under the premise of the strong mass transfer ability in the high-gravity rotating bed end effect area of reservation, rotor subject plot structure is improved
And comparable mass transfer ability therewith is maintained, to reach the anti-blocking effect effect of revolving bed, it is of great significance.
