Description

Technical Field

[0001] The present invention relates to a supergravity device, in particular to a reverse cross-flow supergravity device with an air-blocking ring wall. Background Art

[0002] Existing supergravity devices can be used to intercept and remove suspended particulate matter or soluble gaseous pollutants from gases. However, if a countercurrent supergravity device is used, the contact time between the gas and the liquid is short, and the effect of removing pollutants is relatively limited. If a crosscurrent supergravity device is used, holes are usually dug in the rotating bed base connected to the rotating shaft or the rotating bed base is replaced with support ribs to allow gas to pass through. Therefore, a thicker rotating bed base or reinforced support ribs are required to maintain the structural stability of the rotating bed, thereby increasing the manufacturing limitations of the supergravity device. In addition, when the concentration of suspended particulates is high, if a crosscurrent supergravity device is used, because the openings on the outer surface of the rotating bed are generally small, the intercepted suspended particulates are easily blocked or accumulated in the rotating bed. Summary of the Invention

[0003] The object of the present invention is to provide a reverse cross-flow supergravity device with an air-blocking ring wall, which can avoid the problems that are likely to occur in the above-mentioned background technology.

[0004] The reverse cross-flow supergravity device with an air-blocking annular wall of the present invention comprises an outer shell, a bearing seat, a rotating shaft, a rotating bed unit and a liquid conduit. The outer shell comprises a bottom wall, a top wall and a surrounding wall. The top wall is opposite to the bottom wall and has an air outlet for discharging gas to the outside of the outer shell. The surrounding wall is connected to the bottom wall and the top wall and has an air inlet for introducing gas into the outer shell. The bearing seat is passed through the bottom wall. The rotating shaft is rotatably passed through the bearing seat. The rotating bed unit is arranged in the outer shell. The rotating bed unit comprises a base plate, an annular perforated top plate relative to the base plate in the axial direction of the rotating shaft, a filling layer in the shape of a hollow column and allowing fluid to penetrate, and an air-blocking annular wall. The base plate is connected to the rotating shaft and is spaced apart from the outer shell. The perforated top plate allows fluid to pass through and is connected to the outer shell through a first dynamic seal. The filling layer extends from the base plate in the axial direction of the rotating shaft in the direction opposite to the bearing seat to the perforated top plate, and has a bottom surface in contact with the base plate and in an annular shape, a top surface in contact with the perforated top plate and in an annular shape, an outer peripheral surface connected to the outer peripheral edge of the bottom surface and the outer peripheral edge of the top surface, and an inner peripheral surface connected to the inner peripheral edge of the bottom surface and the inner peripheral edge of the top surface. The inner peripheral surface defines a liquid spraying space located inside. The air-blocking annular wall surrounds a portion of the outer peripheral surface of the top surface adjacent to the filling layer and is spaced apart from the base plate to block the gas introduced into the housing from the air inlet from directly penetrating a portion of the outer peripheral surface of the top surface adjacent to the filling layer. The liquid conduit extends from the outside of the housing into the liquid spraying space and is spaced apart from the rotating bed unit.

[0005] The beneficial effect of the present invention is that the counter-flow supergravity device with an air-blocking ring wall of the present invention can produce the functions and effects of the cross-flow supergravity device in the counter-flow supergravity device without changing the substrate design of the rotating bed unit, and can retain the advantages of the counter-flow supergravity device.

Even more preferably, the tube wall of each liquid conduit branch adjacent to the top surface of the packing layer has no openings.

[0017] Before the present invention is described in detail, it should be noted that similar elements are denoted by the same reference numerals in the following description.

[0018] The present invention will be further described with reference to the following examples. However, it should be understood that the examples are for illustration only and should not be construed as limiting the present invention.

[0019] See Figure 1 and Figure 2 The first embodiment of the reverse cross-flow supergravity device with a gas-blocking ring wall of the present invention includes a housing 1, a bearing seat 2, a rotating shaft 3, a rotating bed unit 4, a liquid conduit 5 and a partition 7.

[0020] The housing 1 includes a bottom wall 11, a top wall 12, and a surrounding wall 13. The top wall 12 is opposite to the bottom wall 11 and has an air outlet 121 for discharging gas out of the housing 1. The surrounding wall 13 is connected to the bottom wall 11 and the top wall 12 and has an air inlet 131 for introducing gas into the housing 1.

[0021] The bearing seat 2 is disposed through the bottom wall 11 .

[0022] The rotating shaft 3 is rotatably disposed in the bearing seat 2 .

[0023] The rotating bed unit 4 is disposed in the housing 1 and includes a base plate 41 , a perforated top plate 44 , a filling layer 42 and a gas blocking ring wall 43 .

[0024] The base plate 41 is connected to the rotating shaft 3 and is spaced apart from the housing 1 .

[0025] The perforated top plate 44 is annular and opposite to the base plate 41 in the axial direction of the rotating shaft 3 . The perforated top plate 44 allows fluid to pass through and is connected to the housing 1 through the first dynamic seal 61 .

[0026] The filling layer 42 is hollow and columnar and allows fluid to penetrate. It extends from the base plate 41 in the axial direction of the rotating shaft 3 in a direction opposite to the bearing seat 2 to the perforated top plate 44. The filling layer 42 has an annular bottom surface 421 in contact with the base plate 41, an annular top surface 422 in contact with the perforated top plate 44, an outer peripheral surface 423 connecting the outer periphery of the bottom surface 421 and the outer periphery of the top surface 422, and an inner peripheral surface 424 connecting the inner periphery of the bottom surface 421 and the inner periphery of the top surface 422. The inner peripheral surface 424 defines a liquid spraying space 40 located therein.

[0027] In this embodiment, the bottom wall 11 of the housing 1 is non-planar, and the distance between the bottom wall 11 and the base plate 41 gradually increases from the bearing seat 2 toward the surrounding wall 13 of the housing 1 .

[0028] The air-blocking ring wall 43 surrounds a portion of the outer peripheral surface 423 adjacent to the top surface 422 of the filling layer 42 and is spaced apart from the substrate 41 to prevent gas introduced into the housing 1 through the air inlet 131 from directly penetrating the portion of the outer peripheral surface 423 adjacent to the top surface 422 of the filling layer 42. In this embodiment, the air-blocking ring wall 43 has a plurality of small holes 431, which are spaced apart and disposed in the air-blocking ring wall 43 away from the top surface 422 of the filling layer 42.

[0029] In this embodiment, the filling layer 42 is in the shape of a hollow cylinder, the air-blocking ring wall 43 is in the shape of a circular ring, and the air-blocking ring wall 43 and the filling layer 42 are coaxially disposed.

[0030] The liquid conduit 5 extends from the outside of the housing 1 into the liquid spraying space 40 and passes through the partition 7 , and is spaced apart from the rotating bed unit 4 .

[0031] The partition plate 7 is disposed above the rotating bed unit 4 and cooperates with the inner circumferential surface 424 of the packing layer 42 to define the liquid injection space 40, thereby preventing gas between the outer circumferential surface 423 and the inner circumferential surface 424 of the packing layer 42 from entering the liquid injection space 40. In this embodiment, the partition plate 7 is connected to the perforated top plate 44 via a second dynamic seal 62.

[0032] In this embodiment, the liquid conduit 5 includes four liquid conduit branches 51 extending toward the base plate 41 of the rotating bed unit 4. The liquid conduit branches 51 are spaced apart from each other and disposed within the liquid spraying space 40. The distal ends of the liquid conduit branches 51 are located within the liquid spraying space 40, and the distal end of each liquid conduit branch 51 has a plurality of openings 52 facing the packing layer 42. In this embodiment, the perforated top plate 44 is annular, the inner periphery of the top surface 422 of the packing layer 42 is circular, and the partition 7 is disc-shaped.

[0033] See Figure 3 The second embodiment of the reverse cross-flow supergravity device with an air-blocking ring wall of the present invention is similar to the first embodiment, except that in the second embodiment, the reverse cross-flow supergravity device does not include a partition 7, and the liquid conduit 5 is passed through the perforated top plate 44 through the third dynamic seal 63 and extends toward the base plate 41 of the rotating bed unit 4 to the liquid injection space 40. The end of the liquid conduit 5 is located in the liquid injection space 40, and the tube wall at the end of the liquid conduit 5 has a plurality of openings 52 facing the filling layer 42.

[0034] When the rotating shaft 3 is externally driven to rotate, causing the rotating bed unit 4 to rotate relative to the housing 1, liquid (e.g., water) enters the liquid spraying space 40 from the opening 52 of the liquid conduit 5 or its branch 51 and is sprayed toward the packing layer 42. The liquid that contacts the packing layer 42 is subjected to the centrifugal force generated by the rotation and flows outward in the radial direction of the rotating shaft 3. Simultaneously, gas containing pollutants (e.g., suspended particulates or soluble gaseous pollutants) is introduced into the housing 1 through the air inlet 131. The gas blocked by the air-blocking ring wall 43 flows and disperses to both sides along the outer side of the air-blocking ring wall 43, thereby preventing excessive concentration from entering the packing layer 42 from a direction near the air inlet 131. After the gas enters the packing layer 42 from the portion of the outer peripheral surface 423 adjacent to the bottom surface 421 of the packing layer 42 (i.e., the portion of the outer peripheral surface 423 away from the top surface 422 of the packing layer 42), it first contacts the liquid in a countercurrent manner in the packing layer 42, which can first carry out the larger particles or gaseous pollutants that are easily dissolved in the liquid through the liquid. Subsequently, the gas in the packing layer 42 turns toward the gas outlet 121 and contacts the liquid in a cross-flow manner, thereby obtaining a longer flow path and contact time with the liquid in the packing layer 42, which can effectively remove smaller particles or gaseous pollutants with a slower dissolution rate. The partition 7 in the first embodiment and the third dynamic seal 63 in the second embodiment can further extend the gas flow path and gas-liquid contact time, thereby enhancing the effect of removing pollutants in a cross-flow manner.

[0035] In the embodiment, the small holes 431 on the air-blocking ring wall 43 can allow the liquid accumulated inside the air-blocking ring wall 43 to be discharged to the outside of the air-blocking ring wall 43 through centrifugal force.

[0036] In addition, in the first embodiment, the liquid conduit branch 51 does not have an opening 52 in the tube wall adjacent to the top surface 422 of the filling layer 42. In the second embodiment, the liquid conduit 5 does not have an opening 52 in the tube wall adjacent to the top surface 422 of the filling layer 42, so that the fine droplets entrained by the gas can be further removed by the filling layer 42 near the top surface 422 of the filling layer 42 (that is, they are not entrained out of the top surface 422 of the filling layer 42), thereby producing a liquid mist removal effect.

[0037] In summary, the counter-flow supergravity device with an air-blocking ring wall of the present invention can produce the functions and effects of a cross-flow supergravity device in a counter-flow supergravity device through the arrangement of the air-blocking ring wall 43 without changing the design of the base plate 41 of the rotating bed unit 4, and can retain the advantages of the counter-flow supergravity device, so the purpose of the present invention can indeed be achieved.

[0038] The above descriptions are merely embodiments of the present invention and should not be used to limit the scope of the present invention. In other words, any simple equivalent changes and modifications made according to the claims and description of the present invention still fall within the scope of the present invention.
