Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
example 1: as shown in the attached figure 1, the concentric corrugated ring rotating bed mainly comprises a cavity 1, wherein a rotor 10 is arranged in the cavity 1, a dynamic seal 2 is arranged between the rotor 10 and the cavity 1, a gas inlet pipe 7 is arranged on the side surface of the cavity 1, and a liquid outlet pipe 11 is arranged on the bottom plate of the cavity 1; a rotating shaft 21 of the rotor 10 penetrates through a bottom plate of the cavity 1, a liquid inlet pipe 3 penetrates through the cavity 1 and a central cavity 22 of the rotor 10 from the upper part of the cavity 1, the liquid inlet pipe 3 with an opening at the upper part and a closed bottom is coaxially arranged with the rotating shaft 21, and a plurality of liquid outlet holes 9 are formed in the pipe wall of the liquid inlet pipe 3; the gas outlet pipe 4 is provided at the upper panel of the chamber 1 and communicates with the central chamber 22 of the rotor 10; the rotor 10 consists of an upper disc 5 and a lower disc 8, a group of concentric corrugated rings 6 which are concentric and have uniformly increased diameters are fixed between the upper disc 5 and the lower disc 8, each concentric corrugated ring 6 consists of a plurality of wave crests 13 and wave troughs 12, and any two concentric corrugated rings 6 are arranged in a staggered mode, so that the wave crest 13 of each concentric corrugated ring 6 is opposite to the wave trough 12 of the adjacent concentric corrugated ring 6; the wave length of the wave crest 13 or the wave trough 12 of the concentric corrugated ring 6 is 0.0001-0.25 times of the circumferential perimeter of the concentric corrugated ring 6, and the height of the wave crest 13 or the wave trough 12 of the concentric corrugated ring 6 is 0.00001-0.5 times of the circumferential radius of the concentric corrugated ring 6.
Preferably, the peaks 13 or the troughs 12 of the concentric corrugated circles 6 are curved in a circular arc or a sinusoidal curve.
As shown in fig. 3, the centrifugal force applied to the peaks 13 of the concentric corrugated rings 6 is smaller than the centrifugal force applied to the valleys 12 of the concentric corrugated rings 6; a jet of liquid 14 falls on the peaks 13 of the concentric corrugated rings 6, part of the liquid passes through the peaks 13, and the rest of the liquid flows to the valleys 12 on both sides of the peaks 13 and passes through the valleys 12 after reaching the valleys 12. Thus, a stream of liquid 14 passing through the first concentric undulating ring 6 forms a circumferential distribution of three streams of liquid (i.e., the circumferential distribution path 16 of liquid passing through the first concentric undulating ring in fig. 3); because the wave trough 12 of the concentric corrugated ring 6 is opposite to the wave crest 20 of the adjacent concentric corrugated ring, the liquid passing through the wave trough 12 falls on the wave crest 20 of the adjacent concentric corrugated ring, part of the liquid passes through the wave crest, and the rest of the liquid moves to the wave trough 15 of the adjacent concentric corrugated ring at the two sides of the wave crest and then passes through the wave trough, so that the liquid 14 forms a circumferential distribution of five liquid strands after passing through the second concentric corrugated ring 19 (namely, the circumferential distribution path 17 of the liquid after passing through the second concentric corrugated ring in fig. 3); by analogy, the liquid 14 passes through the third concentric undulating ring to form seven circumferential distributions of liquid (i.e., the circumferential distribution path 18 of liquid passes through the third concentric undulating ring in fig. 3). The more concentric circles the liquid passes through, the more perfect the circumferential distribution of the liquid formed. The concentric corrugated ring rotor can greatly improve the circumferential distribution of liquid, thereby improving the gas-liquid mass transfer efficiency of the rotating bed.
The working process of the embodiment: gas tangentially enters the cavity 1 from a gas inlet pipe 7 and further enters the rotor 10, and the gas is driven to move circumferentially under the rotation of the concentric corrugated rings 6; meanwhile, the gas flows radially in the rotor 10 under the action of pressure difference, passes through each concentric corrugated ring 6 and is finally discharged through the gas outlet pipe 4; liquid enters the rotor 10 from the liquid inlet pipe 3 through the liquid outlet holes 9 on the pipe wall of the inlet pipe and is thrown out under the action of centrifugal force. Under the action of the concentric corrugated rings 6, a perfect circumferential distribution of the liquid is obtained. The liquid is in intensive contact with the gas while passing through the concentric corrugated rings 6, undergoes mass and heat transfer, and is finally discharged from the liquid outlet pipe 11.
Example 2: when the utility model is used for rectification, gas from the reboiler enters the inner cavity of the cavity 1 from the gas inlet pipe 7, radially passes through the rotor 10, is in countercurrent contact with liquid, and finally enters the condenser for condensation through the gas outlet pipe 4 to obtain a rectification product; part of the condensate enters from the liquid inlet pipe 3 as reflux, enters the rotor 10 through the liquid outlet holes 9 on the liquid inlet pipe, is thrown away with higher speed under the action of centrifugal force, is crushed into fine liquid foam and liquid filaments, and is in countercurrent contact with gas to carry out mass transfer and heat transfer, the liquid enters the reboiler for heating through the liquid outlet pipe 11, and the rectification product is discharged from the reboiler.
Use ethanol-water as the system, under the high gravity revolving bed rotational speed is 1000r/min, adopt the internal diameter to be 400mm, the external diameter is 1000mm, high 100mm open have the concentric circle rotor of sieve mesh and the utility model discloses a concentric ripple circle rotor carries out the full reflux ordinary pressure rectification experiment. The experimental result is as shown in figure 4, and the theoretical column plate number of opening the concentric circle rotor that has the sieve mesh is 4.2 ~ 5.5 pieces, and the theoretical column plate number of concentric ripple circle rotor is than opening the concentric circle rotor that has the sieve mesh and improves 15 ~ 22%, this demonstrates the utility model discloses a concentric ripple circle revolving bed can show to improve liquid circumference and distribute, and its mass transfer efficiency is superior to and opens the concentric circle revolving bed that has the sieve mesh, has wide prospect in industrial application.
