Description

TECHNICAL FIELD

[0001] The present application belongs to the field of gas-liquid mass transfer equipment, and particularly relates to a supergravity device and an energy-optimized supergravity decarbonization system. BACKGROUND

[0002] The statements in this section merely provide background information related to the present application and do not necessarily constitute the prior art.

[0003] The supergravity reactor is a new type of industrial reactor, which utilizes the strong centrifugal force (or supergravity) generated by the high-speed rotating filler bed to continuously disperse and break the liquid to form a larger and continuously updated surface, so that the gas and liquid are fully contacted to obtain a better heat and mass transfer effect.

[0004] In the supergravity reactor, the liquid residence time in the rotating filler bed is generally short (<1s), but when a higher mass transfer effect is required, the filler thickness is generally increased to increase the residence time of the gas and liquid. Considering the mechanical stability of the rotation of the supergravity rotating bed, the rotating filler bed is generally placed in a vertical manner with the rotating shaft. Under the influence of the gravity of the earth, the liquid distribution is closer to the lower side of the filler as it is closer to the outer edge of the rotating shaft, which will cause most of the liquid to pass through the lower side of the filler and the gas to pass through the upper side of the filler with less liquid during the gas-liquid countercurrent mass transfer. The uneven distribution of gas and liquid reduces the mass transfer effect. SUMMARY

[0005] To solve the technical problems in the background art, the present application provides a supergravity device and an energy-optimized supergravity decarbonization system, wherein the supergravity device can improve the uniformity of the gas-liquid distribution in the upper half of the filler, reduce the area of invalid contact between the gas and liquid, and improve the utilization rate of the liquid to ensure sufficient contact between the gas and liquid.

DETAILED DESCRIPTION

[0043] The present application will be further described below in conjunction with the drawings and embodiments.

[0044] It should be noted that the following detailed description is illustrative only, and is intended to provide further description in order to provide a thorough understanding of the present application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the application pertains.

[0046] In the supergravity method gas purification absorption analysis process, the energy consumption mainly comes from the heating regeneration of rich amine solution. The regeneration process usually uses kettle type reboiler to further heat the rich liquid which is preliminarily heated by the lean-rich heat exchanger. The rich liquid is regenerated by the regeneration device and becomes hot lean liquid. The hot lean liquid exchanges heat with the cold rich liquid from the absorption device in the lean-rich heat exchanger. The lean liquid after heat exchange is further cooled and then transported to the absorption device as absorption liquid.

[0047] <supergravity device>

[0048] According to Figure 1 , the embodiment provides a supergravity device, which comprises a shell 8, a cavity in the shell 8, a rotating shaft, a filler 2, a filler lower clamping plate 10 and a filler upper clamping plate 11 in the cavity, a liquid inlet, a liquid outlet 6, a gas inlet 9 and a gas outlet 12 on the shell 8.

[0049] The filler 2 is arranged between the filler upper clamping plate 11 and the filler lower clamping plate 10, the filler upper clamping plate 11 is trapezoidal, and the filler lower clamping plate 10 is provided with an annular protrusion 13; one end of the rotating shaft is arranged in the cavity, the other end of the rotating shaft extends out of the shell 8 and is connected with a driving mechanism (such as a motor).

[0050] In the embodiment, the spray pipes 1 are symmetrically arranged, dynamic balance is maintained, the dynamic part has high stability when rotating at high speed, and the service life of the dynamic part is prolonged.

[0051] The inner wall of the shell 8 is also symmetrically provided with a static disc 4, the rotating shaft is symmetrically provided with a dynamic disc 5, and the dynamic disc 5 is arranged opposite to the lower side of the static disc 4. The liquid inlet is used to introduce liquid and spray the liquid on the inner side of the filler 2 through the spray pipe 1; the liquid on the inner wall of the shell 8 flows into the inner circle of the dynamic disc 5 through the upper surface of the static disc 4 under the action of gravity, is thrown out of the outer circle of the dynamic disc 5 under the action of centrifugal force, and is finally led out of the liquid outlet 6.

[0052] In one or more embodiments, the upper surface of the stationary disc 4 is inclined, funnel-shaped, which facilitates the flow of liquid under the action of gravity.

[0053] The gas inlet 9 is used to introduce the gas to be purified, which flows from the outer circle of the rotating disc 5 to the inner circle under the action of gas pressure, and then flows from the outer side of the packing 2 to the center of the packing. In the process of flowing, the gas contacts and mass transfers with the amine liquid countercurrently, and the purified flue gas leaves the rotor from the center of the rotor, and finally is led out by the gas outlet 12.

[0054] In this embodiment, the rotating shaft extending out of the shell 8 is connected to the shell 8 through a bearing seal 7.

[0055] The liquid enters through the liquid inlet, is sprinkled on the inner circumferential surface of the packing 2 through the spray pipe 1, and flows to the outer edge of the packing under the action of centrifugal force. In this process, the liquid is dispersed, cut, and broken by the large shear force of the packing to form a state that cannot be formed under normal working conditions, such as liquid filaments, liquid films, and liquid droplets. The surface area of the liquid is extremely large and constantly renewed. The tortuous flow channel in the packing further exacerbates the renewal of the liquid surface, thus forming excellent mass transfer and reaction conditions inside the rotating shaft.

[0056] This embodiment takes into account the effect of the earth's gravity on the distribution of liquid in the packing. The upper clamp plate 11 of the packing is a trapezoidal clamp plate, which improves the uniformity of the gas-liquid distribution in the upper half of the packing and reduces the area of ineffective gas-liquid contact. The annular protrusion 13 is added to the lower clamp plate 10 of the packing, as shown in Figure 2 which promotes the lifting of the liquid that converges at the bottom of the packing due to the effect of gravity, improves the utilization rate of the liquid, and enables the gas and liquid to fully contact. Then, the liquid is thrown by the rotor to the inner wall of the shell, and then flows into the inner circle of the rotating disc 5 through the upper surface of the stationary disc 4 under the action of gravity. The liquid is thrown out from the outer circle of the rotating disc 5 under the action of centrifugal force, and finally is led out by the liquid outlet 6. The gas is introduced into the cavity of the supergravity machine through the gas inlet 9, and flows from the outer circle of the rotating disc 5 to the inner circle under the action of gas pressure, and then flows from the outer side of the packing 2 to the center of the packing. In the process of flowing, the gas contacts and mass transfers with the liquid countercurrently, and the purified gas leaves the rotor from the center of the rotor, and finally is led out by the gas outlet 12.

[0057] In one or more embodiments, the vertical distance between the foot and the upper base of the trapezoidal clamp plate of the packing is obtained by calculating the average residence time of the liquid.

[0058] wherein the average residence time of the liquid and the liquid holdup rate are obtained from each other, as formula (2).

[0059] When foamed nickel is used as the packing, the correlation formula of the liquid holdup rate in the high-porosity packing is formula (1).

[0060] (1)

[0061] (2)

[0062] wherein take 100 m / s 2 , take 0.01 m / s, take 10 -6 m 2 / s, is the velocity of the liquid through the packing, is the kinematic viscosity of the liquid, is the volumetric flow of the liquid, is the average of the inner and outer radius of the packing, is the angular velocity of the rotor, r is the radius of the packing, and are the inner radius of the packing and the outer radius of the packing, respectively, is the axial height of the packing.

[0063] The following takes flue gas decarburization as an example:

[0064] The mixed solution of ethanolamine (MEA) and potassium carbonate (K2CO3) is used for flue gas decarburization. The lean amine solution enters the liquid inlet 1 and is sprayed on the inner circumferential surface of the packing 2 through the spray pipe. Under the action of centrifugal force, it flows to the outer edge of the packing. In this process, the liquid is dispersed, cut and broken by the huge shear force of the packing, forming a state that cannot be formed under normal working conditions such as liquid filament, liquid film and liquid droplet. The surface area of the liquid is very large and constantly updated. The tortuous flow channel in the packing further aggravates the update of the liquid surface, so that excellent mass transfer and reaction conditions are formed inside the rotor. Further, considering the influence of the earth's gravity on the liquid distribution in the packing, the clamping plate 11 on the packing is a trapezoidal clamping plate, which improves the uniformity of the gas-liquid distribution in the upper half of the packing and reduces the area of invalid gas-liquid contact. The annular protrusion 13 is added to the lower clamping plate 10 of the packing, which promotes the liquid gathered at the bottom of the packing due to gravity to be lifted again, improves the utilization rate of the liquid, and makes the gas and liquid fully contact. Then, the liquid is thrown to the inner wall of the shell by the rotor, and is led out by the liquid outlet 6 under the action of gravity. The flue gas is introduced into the cavity by the gas inlet 9, and enters the packing 2 from the outer edge of the rotor under the action of gas pressure. It is in countercurrent contact with the amine solution and mass transfer and heat transfer, and the purified flue gas leaves the rotor from the center of the rotor and is finally led out by the gas outlet 12.

[0065] The supergravity device of the embodiment considers the influence of the gravity of the earth on the liquid distribution in the filler, converts the clamping plate on the filler from a horizontal clamping plate into a trapezoidal clamping plate, improves the uniformity of the gas-liquid distribution in the upper half of the filler, and reduces the area of invalid gas-liquid contact; the application increases annular protrusions on the lower clamping plate of the filler, promotes the liquid gathered at the bottom of the filler due to the influence of gravity to be lifted again, improves the liquid utilization rate, and makes the gas and liquid fully contact.
