Description

Parabolical revolution gas-liquid heat-transfer mass transfer apparatus

The utility model is a parabolical revolution gas-liquid heat-transfer mass transfer apparatus, belongs to heat and mass consersion unit between gas-liquid phase.

Utilize centrifugal force field to strengthen the existing history for many years of gas-liquid white heat mass transfer technology, on technology is used, had suitable level.Relevant revolving bed rotor and rotor filling-material structure, existing multinomial relevant patent, as BP " improvement of gas-liquid two-phase contact device " (Improvements in liquid-gascontact apparatus, the patent No.: UK1366312) filler that is adopted is a radial radiation shape corrugated plating, the plate face of this corrugated plating and the shaft parallel of rotor, be the radial radiation shape, the relative wire packing of this filler is less to the resistance of gas flow, but have following shortcoming: (1) runner equivalent diameter d and radial distance r are approximated to direct ratio, and the approximate cube with radial distance r of the gaseous pressure variable gradient of radial direction is inversely proportional to, for the gas pressure drop that keeps inner and outer ring in allowed limits, the inner and outer ring spacing of this filler is less, this has just shortened gas-liquid alternate time of contact, thereby influences mass transfer effect; (2) though filler plate is the structured packing of corrugated circular ring type, but under the high speed rotation status, flowing of liquid has not been that the simple shaped liquid film along the filler plate surface flows, but under centrifugal action, fallen out, forming drop moves between plate, be easy to generate the stifled or liquid flooding phenomenon of liquid, be unfavorable for interphase mass transfer and stable operation; (3) filler plate quantity is many, and the dynamic balancing under the fast state is difficult to meet the demands, and also is unfavorable for production, installation and maintenance.Chinese patent: " the horizontal revolving bed of super gravity field of band resistance pumping equipment " (patent No.: 91226917.0), " rotating bed super gravity field transmission and reaction unit " (patent No.: 91229204.0), " donut thin plate filler revolving bed gas-liquid mass transfer reactor " (patent No.: ZL95214611.8), a something in common of above-mentioned patent is to adopt circular ring type structured packing (surface configuration difference), liquid is because the garden pipe outflow that has aperture in the middle of the filler plate, gas circumferentially flows into from shell, gas-liquid is in the radial direction reverse flow, because the gas-liquid fluid motion under the high speed rotation status is very complicated, the liquid that very easily appears at the gas inflow direction is blown open fully, make liquid distribution inhomogeneous, when air volume, can produce entrained liquid and gas short circuit phenomenon; And when big flow quantity, being prone to the stifled and liquid flooding phenomenon of liquid, these all are unfavorable for gas-liquid interphase mass transfer, and the alternate resistance of gas-liquid during big flow is big, be difficult to stable operation, moreover above-mentioned patent are not suitable for the alternate augmentation of heat transfer of gas-liquid.Chinese patent " the rotary packed bed gas-liquid heat-transfer mass transfer apparatus of gas the axial flow type " (patent No.: ZL97212054.8) be applicable to gas-liquid mass transfer mass transfer under the gas liquid cross-flow state, and gas-liquid two-phase fluid is carried out adverse current or following current at axial direction, particularly during the atmosphere flow quantity, alternate flow resistance is big, reason is under rotation status (particularly high speed rotation status), fluid is motion from inside to outside under centrifugal action, liquid can be flowed by interior hoop outer shroud rapidly in rotor, in filler rotor axial positions from lower to upper, ring was many in distribution of liquid went out to reproduce, outer shroud is few, in the phenomenon of certain axial positions no liquid, its shape is similar to the parabolic type cone; And because gas density is little, outwards the motion liquid that is far from is obvious like that to be subjected to centrifugal action, so during the gas motion in the middle of rotor, less than contacting, and only pass filler in certain limit, so promptly be unfavorable for the white heat mass transfer with liquid, also increased simultaneously the resistance of motion of gas, make the blower fan power consumption increase, thereby cause vibration to strengthen, noise increases.Actual measurement shows that at the bottom and the interior ring of this device rotor, heat and mass transfer coefficient is bigger, and the white heat mass transfer effect is good; And sharply reduce at the top and the outer shroud heat and mass transfer coefficient of rotor, gas-liquid white heat mass transfer effect is poor.

The purpose of this utility model is exactly in order to overcome and to solve existing gas-liquid heat-transfer mass transfer apparatus both domestic and external and technology exists gas-liquid to lack alternate time of contact, easily produce the stifled or liquid flooding of liquid, be unfavorable for gas-liquid interphase mass transfer and stable operation, be unsuitable for the alternate heat and mass transfer enhancement of gas-liquid, particularly during the atmosphere flow quantity, alternate flow resistance is big, make the blower fan power consumption big, vibration is strong, noise is big, gas-liquid white heat mass transfer effect is poor, filler plate quantity is many, inconvenience is produced, install, safeguard, heat and mass equipment is huge, efficient is low, the shortcoming and the problem of the big grade of energy consumption, a kind of kinetic characteristic that can make full use of fluid in the rotating centrifugal field of force of research invention, make the flow resistance of gas-liquid reach minimum state, the gas pressure loss is little, corresponding blower fan is low in energy consumption, noise is little, make the alternate full contact of gas-liquid, the effect of gas-liquid white heat mass transfer is good, be applicable to the cooling tower (being cooling tower) or the industrial cooling tower of central air-conditioning, can greatly strengthen the alternate contact of gas-liquid, reach required cooling effect, volume is little, fluid resistance is low, can purify air effectively and the parabolical revolution gas-liquid heat-transfer mass transfer apparatus of air dewetting.
