Description

A supergravity device and energy-optimized supergravity decarbonization system

[0001] This invention claims priority to the Chinese patent application filed with the Patent Office of China on November 29, 2023, with application number 202311613779.X and invention name “A Supergravity Device and Energy-Optimized Supergravity Decarbonization System”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present invention belongs to the field of gas-liquid mass transfer equipment, and in particular relates to a supergravity device and an energy-optimized supergravity decarbonization system. Background Art

[0003] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0004] The supergravity reactor is a new type of industrial reactor that uses the strong centrifugal force (or supergravity) generated by a high-speed rotating packing bed to continuously disperse and break up the liquid to form a larger and constantly renewed surface, allowing the gas and liquid to fully contact, thereby achieving better heat and mass transfer effects.

[0005] Among them, the residence time of liquid in the rotating packed bed in the supergravity reactor is generally short (<1s), but when a higher mass transfer effect is required, it is generally necessary to increase the thickness of the packing to increase the residence time of the gas and liquid. Considering the mechanical stability of the rotation of the supergravity rotating bed, the rotating packed bed is generally placed with the rotating axis vertical. Under the influence of the earth's gravity, the closer the liquid is to the outer edge of the rotating axis, the closer it is to the bottom of the packing. This will result in the process of gas-liquid countercurrent mass transfer, where most of the liquid passes through the bottom of the packing, and the gas passes through the top of the packing where there is less liquid. The gas and liquid are unevenly distributed, thereby reducing the mass transfer effect.

DETAILED DESCRIPTION

[0045] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0046] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0047] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0048] In the high-gravity gas purification absorption and desorption process, energy consumption primarily comes from heating and regenerating the rich amine solution. The regeneration process typically involves further heating the rich solution, initially heated in the lean-rich heat exchanger, in a kettle reboiler. The rich solution then passes through a regeneration unit and becomes hot lean solution. The hot lean solution then exchanges heat with the cold rich solution from the absorber in the lean-rich heat exchanger. After this heat exchange, the lean solution is further cooled and then re-delivered to the absorber as absorption liquid.

[0049] <Supergravity Device>

[0050] According to Figure 1, this embodiment provides a supergravity device, which includes: a shell 8, a cavity is provided in the shell 8, and a rotating shaft, a filler 2, a lower filler splint 10 and an upper filler splint 11 are provided in the cavity; the shell 8 is also provided with a liquid inlet, a liquid outlet 6, a gas inlet 9 and a gas outlet 12.

[0051] The packing 2 is arranged between the upper packing plate 11 and the lower packing plate 10, the upper packing plate 11 is trapezoidal, and the lower packing plate 10 is provided with an annular protrusion 13; one end of the rotating shaft is arranged in the cavity, and the other end extends out of the shell 8 and is connected to the driving mechanism (such as a motor, etc.); the packing 2 is symmetrically arranged on both sides of the rotating shaft, and spray pipes 1 are arranged on both sides of the rotating shaft, and the spray pipes 1 are connected to the liquid inlet.

[0052] In this embodiment, the spray pipes 1 are symmetrically arranged to maintain dynamic balance, thereby ensuring that the moving parts have high stability when rotating at high speeds and extending the service life of the moving parts.

[0053] The inner wall of the housing 8 is symmetrically provided with a stator plate 4, and the rotating shaft is symmetrically provided with a rotating plate 5, disposed directly below the stator plate 4. The liquid inlet is used to introduce liquid and spray it onto the inner surface of the packing 2 through the spray pipe 1. Liquid on the inner wall of the housing 8 flows through the upper surface of the stator plate 4 under the action of gravity into the inner ring of the rotating plate 5. It is then ejected from the outer ring of the rotating plate 5 under the action of centrifugal force and finally discharged through the liquid outlet 6.

[0054] In one or more embodiments, the upper surface of the stator plate 4 is inclined and funnel-shaped, which promotes the flow of liquid under the action of gravity.

[0055] The gas inlet 9 is used to introduce the gas to be purified. Under the action of gas pressure, the gas flows from the outer ring of the moving disk 5 to the inner ring, and then flows from the outside of the packing 2 to the center of the packing. During the flow process, the gas contacts the amine liquid in countercurrent and transfers mass and heat. The purified flue gas leaves the rotor from the center of the rotor and is finally discharged from the gas outlet 12.

[0056] In this embodiment, the rotating shaft extending out of the housing 8 is connected to the housing 8 via a bearing seal 7 .

[0057] Liquid enters through the liquid inlet and is sprayed onto the inner circumference of packing 2 through spray pipe 1. Centrifugal force causes it to flow toward the outer edge of the packing. During this process, the liquid is dispersed, cut, and shattered by the enormous shear force of the packing, forming liquid filaments, liquid films, and droplets—forms not possible under conventional operating conditions. The liquid's surface area is extremely large and constantly renewed. The tortuous flow paths within the packing further accelerate the renewal of the liquid surface, creating excellent mass transfer and reaction conditions within the rotating shaft.

[0058] This embodiment takes into account the influence of gravity on the distribution of liquid within the packing. The upper packing plate 11 is a trapezoidal plate, which improves the uniformity of gas-liquid distribution in the upper half of the packing and reduces areas of ineffective gas-liquid contact. An annular protrusion 13 is added to the lower packing plate 10, as shown in Figure 2. This promotes the re-elevation of liquid that has accumulated at the bottom of the packing due to gravity, improving liquid utilization and ensuring sufficient gas-liquid contact. The liquid is then flung by the rotor onto the inner wall of the housing. Under the influence of gravity, it flows through the upper surface of the stator plate 4 into the inner ring of the rotating plate 5. Centrifugal force ejects it from the outer ring of the rotating plate 5 and finally discharges it through the liquid outlet 6. Gas is introduced into the hypergravity machine chamber through the gas inlet 9. Under the influence of gas pressure, it flows from the outer ring of the rotating plate 5 to the inner ring, and then from the outside of the packing 2 to the center of the packing. During its flow, the gas engages with the liquid in countercurrent flow, transferring mass and heat. The purified gas leaves the rotor at its center and is finally discharged through the gas outlet 12.

[0059] In one or more embodiments, the vertical distance between the foot of the trapezoidal upper plate of the filler and the upper bottom is obtained by calculating the average residence time of the liquid.

[0060] Among them, the average residence time of the liquid t and the liquid holdup ε L The formula (2) can be derived from each other.

[0061] When nickel foam is used as filler, estimate the liquid holdup ε in high porosity filler L The correlation formula is as shown in formula (1).

[0062] Where g0 is 100m / s 2 , V0 is 0.01m / s, υ0 is 10 -6 m 2 / s,V L is the speed of liquid passing through the packing, υ L is the kinematic viscosity of the liquid, Q L is the liquid volume flow rate, r avg is the average value of the inner and outer radii of the packing, ω is the angular velocity of the rotor, r is the radius of the packing, r1 and r2 are the inner and outer radii of the packing respectively, and h is the axial height of the packing.

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

[0064] Flue gas decarbonization is achieved using a mixed solution of ethanolamine (MEA) and potassium carbonate (K2CO3). Lean amine liquid enters through the liquid inlet 1 and is sprayed onto the inner circumference of the packing 2 through a spray pipe. Under the influence of centrifugal force, it flows toward the outer edge of the packing. During this process, the liquid is dispersed, cut, and shattered by the enormous shear force of the packing, forming liquid filaments, liquid films, and droplets—states that cannot form under conventional operating conditions. The liquid surface area is extremely large and constantly renewed. The tortuous flow paths in the packing further accelerate the renewal of the liquid surface, thus creating excellent mass transfer and reaction conditions within the rotor. Furthermore, considering the influence of gravity on the liquid distribution within the packing, the upper packing plate 11 is a trapezoidal plate, which improves the uniformity of gas-liquid distribution in the upper half of the packing and reduces the area of ​​ineffective gas-liquid contact. An annular protrusion 13 is added to the lower packing plate 10 to promote the re-lift of liquid that has accumulated at the bottom of the packing due to gravity, improving liquid utilization and ensuring sufficient gas-liquid contact. The liquid is then thrown by the rotor onto the inner wall of the housing and discharged through the liquid outlet 6 under the influence of gravity. Flue gas is introduced into the cavity through the gas inlet 9 and enters the packing 2 from the outer edge of the rotor under the action of gas pressure. It contacts the amine liquid in countercurrent and transfers mass and heat. The purified flue gas leaves the rotor from the center and is finally led out through the gas outlet 12.

[0065] The supergravity device of this embodiment takes into account the influence of the earth's gravity on the distribution of liquid in the packing, and transforms the upper splint of the packing from a horizontal splint into a trapezoidal splint, thereby improving the uniformity of the gas-liquid distribution in the upper half of the packing and reducing the area of ​​ineffective contact between gas and liquid; the present invention adds an annular protrusion to the lower splint of the packing to promote the re-uptake of the liquid gathered at the bottom of the packing due to the influence of gravity, thereby improving the utilization rate of the liquid and ensuring sufficient contact between gas and liquid.

[0066] <Energy Optimized High Gravity Decarbonization System>

[0067] According to Figure 3, this embodiment provides an energy-optimized high-gravity decarbonization system, which includes: a flue gas blower 14, a first high-gravity device 15, a rich amine liquid tank 16, a rich amine liquid regulating valve 17, a rich amine liquid pump 18, a lean-rich liquid heat exchanger 19, a steam-rich liquid heat exchanger 20, a steam-cooling water heat exchanger 21, a lean amine liquid-cooling water heat exchanger 22, a tubular falling film reboiler 23, a gas-liquid separator 24, a hot liquid pump 25, a steam blower 26, a second high-gravity device 27, a lean amine liquid tank 28, a CO2-water separator 29, a condensate pump 30 and a lean liquid pump 31.

[0068] The first hypergravity device 15 serves as a hypergravity absorption machine, and the second hypergravity device 27 serves as a hypergravity analyzer. Moreover, the first hypergravity device and the second hypergravity device are the same as the hypergravity device described above.

[0069] Specifically, the flue gas blower 14 is connected to the gas inlet of the first supergravity device 15, and the liquid outlet of the supergravity absorber is connected to the uppermost end of the outer wall of the rich amine liquid tank 16, so that the rich amine liquid flows along the tank wall to reduce amine liquid foaming.

[0070] The bottom of rich amine tank 16 is connected to the inlet of rich amine pump 18, the outlet of which is connected to rich amine regulating valve 17 and lean-rich liquid heat exchanger 19. By opening rich amine regulating valve 17, rich amine liquid can be introduced into the liquid inlet of the absorption unit for further CO2 absorption, thereby increasing the actual CO2 loading of the rich amine liquid. This increases the liquid flow rate of the absorption unit and improves the gas purification rate. Furthermore, the high CO2 loading of rich amine liquid allows for more CO2 to be released per unit energy consumption, improving the desorption efficiency of the desorption unit and reducing system energy consumption.

[0071] The rich liquid outlet of the lean-rich liquid heat exchanger 19 is connected to the rich liquid inlet of the steam-rich liquid heat exchanger 20 , and the rich liquid outlet of the steam-rich liquid heat exchanger 20 is connected to the liquid inlet of the tubular falling film reboiler 23 .

[0072] Among them, the advantages of the falling film reboiler are: the solution flows in the reboiler in a film-like manner, and the heat transfer coefficient is high; the residence time is short, and it is not easy to cause material deterioration; it is suitable for foaming materials, and the whole process of the material and liquid does not form too much impact, avoiding the formation of foam; it can evaporate materials with high concentration and high viscosity; it can use low temperature difference evaporation; the liquid retention volume is small, and the falling film reboiler can operate quickly according to changes in energy supply, feed amount, concentration, etc.

[0073] MCM-41 molecular sieve regeneration solid catalyst is added to the path of the liquid flowing through the tubular falling film reboiler 23 to promote the decomposition of the amine solution.

[0074] The material outlet of the tubular falling film reboiler 23 is connected to the gas-liquid separator 24 . The liquid in the gas-liquid separator 24 is sent to the liquid inlet of the second supergravity device 27 by the hot liquid pump 25 . The steam in the gas-liquid separator 24 is introduced into the gas inlet of the second supergravity device 27 .

[0075] Inside the second hypergravity device 27, steam strips the hot amine liquid. The large concentration difference in the decomposition products between the steam and the hot amine liquid allows CO2 to transfer more quickly from the liquid phase to the gas phase. Simultaneously, the partial liquefaction of the water vapor provides heat for the amine liquid decomposition reaction. The hypergravity machine's advantage in a "three-transmission, one-reaction" process accelerates the regeneration of the amine liquid. A steam blower 26 is connected to the gas outlet of the second hypergravity device 27, delivering the CO2-water vapor mixture to the steam-rich liquid heat exchanger 20. After heat exchange, the mixture is then introduced into the steam-cooling water heat exchanger 21 for further cooling, condensing the water vapor, and purifying the CO2.

[0076] The inlet of the condensate pump 30 is connected to the bottom of the CO2-water separator 29, and the condensate is transported to the lean amine liquid tank 28. The lean amine liquid tank 28 is connected to the liquid outlet of the second supergravity device 27. The collected lean liquid is transported by the lean liquid pump 31 to the lean-rich liquid heat exchanger 19 for heat exchange, and then further cooled by the lean amine liquid-cooling water heat exchanger 22 before being sent to the first supergravity device 15 as absorption liquid.

[0077] In one or more embodiments, the lean-rich liquid heat exchanger 19, the steam-rich liquid heat exchanger 20, the steam-cooling water heat exchanger 21, and the lean amine liquid-cooling water heat exchanger 22 all employ printed circuit heat exchangers (PCHEs). PCHEs are compact in design and, under the same heat load and pressure drop, are typically 4-6 times smaller and lighter than conventional shell-and-tube heat exchangers.

[0078] It should be noted that in other embodiments, those skilled in the art may modify the

[0079] The specific models and structures of the lean-rich liquid heat exchanger, steam-rich liquid heat exchanger, steam-cooling water heat exchanger and lean amine liquid-cooling water heat exchanger are selected and will not be described in detail here.

[0080] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
