Description

Technical Field

[0001] This invention relates to a hypergravity device, and more particularly to a double-layer absorption hypergravity device. Background Technology

[0002] In the waste gas treatment industry, multiple treatment devices (such as gravity devices, scrubbing absorption towers, activated carbon adsorption towers, dust collectors, etc.) are usually connected in series to treat various pollutants (such as sulfur oxides, nitrogen oxides, carbon dioxide, suspended particulates, etc.) in waste gas (such as flue gas), thus requiring a large amount of configuration space.

[0003] Combining multiple treatment units that can absorb different pollutants in a gas into a single device can help reduce the required configuration space. However, the liquids used by each treatment unit (e.g., alkaline liquids, acidic liquids, water, etc.) are easily mixed in a single device, which can lead to changes in the composition of individual liquids and reduce the absorption effect. Summary of the Invention

[0004] The primary objective of this invention is to provide a double-layer absorption-type hypergravity device that overcomes the shortcomings of the aforementioned background technology.

[0005] The double-layer absorption-type hypergravity device of the present invention includes a shell, a rotating bed unit, a rotating shaft, a washing layer, a baffle unit, and a conduit. The rotating bed unit is disposed within the shell and spaced apart from it, defining an internal flow space. The rotating shaft connects to the rotating bed unit and extends from it to the outside of the shell. The washing layer is disposed within the shell and spaced above the rotating bed unit, cooperating with it to define an airflow space. The baffle unit is disposed in the airflow space and includes a bottom baffle and a top baffle. The bottom baffle is in close contact with the shell and includes an upper bottom surface and a lower bottom surface opposite to the upper bottom surface. The bottom baffle forms a bottom through-hole penetrating the upper bottom surface and the lower bottom surface, allowing the flow space to communicate with the washing layer. The top baffle is spaced above the bottom baffle and spaced apart from the shell, completely blocking the bottom through-hole in the axial direction of the rotating shaft. The conduit extends from the outside of the housing into the flow space and is adapted to introduce liquid into the flow space.

[0006] Preferably, the bottom baffle further includes a bottom liquid-blocking ring wall that extends upward from the upper surface of the bottom and surrounds the bottom through hole.

[0007] Preferably, the top baffle extends radially along the rotation axis.

[0008] Preferably, the housing includes an air inlet, an air outlet, an upper liquid outlet, and a lower liquid outlet. The air inlet is adapted to introduce gas into the housing. The air outlet is adapted to discharge gas that has passed through the scrubbing layer. The upper liquid outlet is adjacent to the bottom upper surface of the bottom baffle. The lower liquid outlet is located at the bottom of the housing.

[0009] Preferably, the rotating bed unit includes a substrate and a filling layer extending upward from the substrate, the filling layer and the substrate together defining the flow space, and the rotating shaft is connected to the substrate of the rotating bed unit and extends from the substrate to the outside of the housing.

[0010] Preferably, the double-layer absorption-type supergravity device further includes a rinsing liquid dispersion unit, which is suitable for dispersing the rinsing liquid in the rinsing layer.

[0011] Preferably, the lower surface of the bottom baffle is connected to the top of the rotating bed unit via a dynamic seal.

[0012] Preferably, the conduit extends from the outside of the housing through the bottom liquid-blocking ring wall and the bottom through hole into the flow space.

[0013] The second objective of this invention is to provide a double-layer absorption-type hypergravity device that can overcome the shortcomings of the aforementioned background technology.

[0014] The dual-layer absorption-type hypergravity device of the present invention comprises a shell, a rotating bed unit, a rotating shaft, a washing layer, a baffle unit, and a conduit. The rotating bed unit is disposed within the shell and spaced apart from it, defining an internal flow space. The rotating shaft connects to the rotating bed unit and extends from the rotating bed unit to the outside of the shell. The washing layer is disposed within the shell and spaced above the rotating bed unit, cooperating with it to define an airflow space therebetween. The baffle unit is disposed within the airflow space and includes a bottom baffle, at least one middle baffle, and a top baffle. The bottom baffle is tightly fitted to the outer casing. The bottom baffle includes an upper bottom surface and a lower bottom surface opposite to the upper bottom surface. The bottom baffle forms a bottom through-hole penetrating the upper bottom surface and the lower bottom surface, allowing the flow space to communicate with the rinsing layer. At least one intermediate baffle is spaced above the bottom baffle and spaced from the outer casing, completely obscuring the bottom through-hole in the axial direction of the rotation shaft. Each intermediate baffle includes a middle upper surface and a middle lower surface opposite to the middle upper surface, forming a middle through-hole penetrating the middle upper surface and the middle lower surface. A top baffle is spaced above the at least one intermediate baffle and spaced from the outer casing, completely obscuring the middle through-hole in the axial direction of the rotation shaft. The conduit extends from the outside of the outer casing into the flow space and is adapted to introduce liquid into the flow space.

[0015] Preferably, each baffle further includes a liquid-resistant ring wall that extends upward from the upper surface and surrounds the through hole.

[0016] Preferably, each baffle extends radially along the rotation axis.

[0017] The beneficial effects of the present invention are as follows: the double-layer absorption supergravity device can absorb different pollutants in the gas, and can prevent the rinsing liquid from flowing into the flow space and mixing with the liquid supplied by the conduit, and can make the gas flowing through the bottom through hole uniformly enter the rinsing layer.

[0022] Before the invention is described in detail, it should be noted that similar elements are represented by the same numbers in the following description.

[0023] The present invention will be further described with reference to the following embodiments, but it should be understood that the embodiments are for illustrative purposes only and should not be construed as limiting the implementation of the present invention.

[0024] See Figure 1 The first embodiment of the double-layer absorption-type supergravity device 1 of the present invention includes a shell 2, a rotating bed unit 3, a rotating shaft 4, a rinsing layer 5, a baffle unit 6, a conduit 7, a dynamic sealing element 8, and a rinsing liquid dispersion unit 9.

[0025] The housing 2 includes an air inlet 21, an air outlet 22, an upper liquid outlet 23, and a lower liquid outlet 24. The air inlet 21 is adapted to introduce gas into the housing 2. The air outlet 22 is located at the top of the housing 2 and is adapted to discharge gas passing through the scrubbing layer 5. The lower liquid outlet 24 is located at the bottom of the housing 2.

[0026] The rotating bed unit 3 is disposed within and spaced apart from the housing 2, defining an internal flow space 30. In this embodiment, the rotating bed unit 3 is a rotating packed bed. The rotating packed bed includes a substrate 31 and a hollow columnar filling layer 32 extending upward from the substrate 31. The filling layer 32 and the substrate 31 together define the flow space 30. The material filled in the filling layer 32 is selected from wire mesh, glass beads, plastic fillers, activated carbon, zeolite, metal plates, or combinations thereof. In this embodiment, the air inlet 21 is disposed on the side of the housing 2, suitable for introducing gas through the filling layer 32 into the flow space 30.

[0027] The rotating shaft 4 is connected to the base plate 31 of the rotating bed unit 3 and extends from the base plate 31 to the outside of the outer shell 2.

[0028] In this embodiment, the rinsing layer 5 is disposed inside the outer shell 2 and spaced above the rotating bed unit 3, and cooperates with the rotating bed unit 3 to define an airflow space 50 therebetween, and the rinsing layer 5 is wire mesh.

[0029] In other embodiments of the present invention, the rinsing layer 5 is spaced apart from the outer shell 2 and has a hollow columnar structure similar to the filling layer 32 of the rotary filling bed described above (not shown).

[0030] The baffle unit 6 is disposed in the airflow space 50. The baffle unit 6 includes a bottom baffle 61 and a top baffle 62. The bottom baffle 61 is in close contact with the outer casing 2. The bottom baffle 61 includes a bottom upper surface 611, a bottom lower surface 612 opposite to the bottom upper surface 611, and a bottom liquid-blocking ring wall 613. The bottom baffle 61 forms a bottom through hole 610 that penetrates the bottom upper surface 611 and the bottom lower surface 612, so that the flow space 30 can communicate with the washing layer 5. The upper liquid outlet 23 is adjacent to the bottom upper surface 611 of the bottom baffle 61. The bottom lower surface 612 is connected to the top of the rotating bed unit 3 through the dynamic seal 8. The bottom liquid-blocking ring wall 613 extends upward from the bottom upper surface 611 and surrounds the bottom through hole 610. The top baffle 62 is spaced above the bottom baffle 61 and spaced apart from the outer casing 2, and completely covers the bottom through hole 610 in the axial direction of the rotating shaft 4. The top baffle 62 extends radially in the rotating shaft 4.

[0031] The conduit 7 extends from the outside of the housing 2 through the side of the housing 2, the bottom liquid-blocking ring wall 613 and the bottom through hole 610 into the flow space 30.

[0032] In this embodiment, the rinsing liquid dispersion unit 9 is disposed above the rinsing layer 5, and is adapted to disperse the rinsing liquid from the outside of the outer shell 2 onto the upper surface of the rinsing layer 5, and the rinsing liquid dispersion unit 9 is a spray pipe.

[0033] In other embodiments of the present invention, the rinsing liquid dispersion unit 9 extends from the outside of the housing 2 into the space surrounded by the hollow columnar rinsing layer 5, and is adapted to disperse the rinsing liquid on the inner annular surface (not shown) of the hollow columnar rinsing layer 5.

[0034] When the rotating shaft 4 is externally driven to rotate, causing the rotating bed unit 3 to rotate relative to the housing 2, the conduit 7 supplies a liquid (such as an alkaline absorbent) that can be used to absorb contaminants in the gas. This liquid enters the flow space 30 through an opening (not shown) on the conduit 7. Driven by centrifugal force, the liquid moves radially from the inside to the outside along the rotating shaft 4 and is dispersed into tiny droplets, filaments, or films in the filling layer 32 by centrifugal force, thereby increasing the gas-liquid mass transfer rate. Simultaneously, gas containing contaminants (such as acidic and alkaline gases) is introduced into the housing 2 through the inlet 21, where it comes into countercurrent contact with the liquid in the filling layer 32 radially along the rotating shaft 4 and passes through the filling layer 32 from the outside to the inside.

[0035] Subsequently, the liquid that has absorbed some of the contaminants (such as acidic gases) flows out from the lower outlet 24 at the bottom of the outer casing 2; the gas that still contains some contaminants (such as alkaline gases) flows upward to the airflow space 50 and through the bottom through hole 610 and the space between the top baffle 62 and the outer casing 2, uniformly entering the rinsing layer 5, where it comes into countercurrent contact with the rinsing liquid (such as acidic or neutral rinsing liquid) introduced by the rinsing liquid dispersion unit 9 and is absorbed. Finally, the gas passing through the rinsing layer 5 is discharged from the air outlet 22 at the top of the outer casing 2; the rinsing liquid that has absorbed some of the contaminants (such as alkaline gases) flows through the bottom upper surface 611 of the top baffle 62 and the bottom baffle 61, and flows out from the upper outlet 23 on the side of the outer casing 2.

[0036] See Figure 2 The second embodiment of the double-layer absorption-type hypergravity device 1 of the present invention is similar to the first embodiment, except that in the second embodiment, the baffle unit 6 further includes a middle baffle 63. The middle baffle 63 is spaced above the bottom baffle 61 and spaced apart from the outer shell 2, and completely blocks the bottom through hole 610 in the axial direction of the rotation shaft 4. The middle baffle 63 includes a middle upper surface 631, a middle lower surface 632 opposite to the middle upper surface 631, and a middle liquid-resistant ring wall 633. The middle baffle 63 forms a middle through hole 630 penetrating the middle upper surface 631 and the middle lower surface 632. The middle baffle 63 extends radially in the rotation shaft 4. The middle liquid-resistant ring wall 633 extends upward from the middle upper surface 631 and surrounds the middle through hole 630. The top baffle 62 is spaced above the middle baffle 63 and spaced apart from the outer shell 2, and completely blocks the middle through hole 630 in the axial direction of the rotation shaft 4.

[0037] In this second embodiment, gas containing some contaminants (such as alkaline gas) flows upward into the airflow space 50 and passes through the bottom through-hole 610, the middle through-hole 630, the space between the middle baffle 63 and the outer shell 2, and the space between the top baffle 62 and the outer shell 2, uniformly entering the rinsing layer 5. Finally, the rinsing liquid that has absorbed some contaminants (such as alkaline gas) flows through the top baffle 62, the upper middle surface 631 of the middle baffle 63, and the lower upper bottom surface 611 of the bottom baffle 61, and flows out from the upper liquid outlet 23 on the side of the outer shell 2.

[0038] See Figure 3 The third embodiment of the double-layer absorption-type hypergravity device 1 of the present invention is similar to the second embodiment, except that in the third embodiment, the baffle unit 6 includes two middle baffles 63. The middle baffles 63 are spaced vertically above the bottom baffle 61 and spaced apart from the outer shell 2. The lower middle baffle 63 completely blocks the bottom through hole 610 in the axial direction of the rotation shaft 4. Each middle baffle 63 includes an upper middle surface 631, a lower middle surface 632 opposite to the upper middle surface 631, and a liquid-resistant ring wall 633. Each middle baffle 63 forms a through hole 630 penetrating the upper middle surface 631 and the lower middle surface 632. The upper middle baffle 63 completely blocks the through hole 630 of the lower middle baffle 63 in the axial direction of the rotation shaft 4. Each middle baffle 63 extends radially on the rotation shaft 4. The intermediate resistance ring wall 633 extends upward from the upper surface 631 and surrounds the intermediate through hole 630. The top baffle 62 is spaced above the intermediate baffle 63 and spaced apart from the outer casing 2, and completely blocks the intermediate through hole 630 of the upper intermediate baffle 63 in the axial direction of the rotation shaft 4.

[0039] In this third embodiment, gas containing some contaminants (such as alkaline gas) flows upward into the airflow space 50 and passes through the bottom through-hole 610, the middle through-hole 630, the space between the middle baffle 63 and the outer shell 2, and the space between the top baffle 62 and the outer shell 2, uniformly entering the rinsing layer 5. Finally, the rinsing liquid that has absorbed some contaminants (such as alkaline gas) flows through the top baffle 62, the upper middle surface 631 of the middle baffle 63, and the upper bottom surface 611 of the bottom baffle 61, and flows out from the upper liquid outlet 23 on the side of the outer shell 2.

[0040] In summary, the double-layer absorption supergravity device 1 of the present invention, through the setting of the baffle unit 6, can prevent the rinsing liquid from flowing into the flow space 30 and mixing with the liquid supplied by the conduit 7 in a single device that can absorb different pollutants in the gas, and can make the gas flowing through the bottom through hole 610 uniformly enter the rinsing layer 5 so as to uniformly contact the rinsing liquid. Therefore, it can indeed achieve the purpose of the present invention.

[0041] The above description is merely an embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the claims and description of the present invention shall still fall within the scope of the present invention.
