Description

Technical Field

[0001] This invention relates to packed towers, and more particularly to a packing material, a packed tower, and a method for preparing it. Background Technology

[0002] A packed tower is a unit operation device in which a certain height of packing is filled into a cylindrical tower body, so that the liquid phase flows from top to bottom in a film along the surface of the packing, and the gas phase flows from bottom to top. Mass transfer is achieved through close contact between the two phases on the surface of the packing.

[0003] Packing material is an important component of packed towers. Chinese invention patent CN118663210A, published on September 20, 2024, discloses a high-throughput packing material for packed towers. This packing material is a structured packing composed of multiple packing plates placed parallel to each other within the packed tower. The packing plates are corrugated plates, with the corrugation direction of each plate perpendicular to the centerline of the packed tower. This invention provides ample space for gas-liquid flow, achieves high packing throughput, and effectively prevents impurities from clogging the tower. It improves gas flow direction, forms liquid film exchange, facilitates lateral gas diffusion, and reduces pressure loss. It has a simple structure, is easy to assemble, and is low in cost.

[0004] The drawback of this invention is that the axial length of its packing is poorly adjustable, making it difficult to adapt to packed towers of different sizes and resulting in poor versatility. Summary of the Invention

[0005] Objectives of the invention: The present invention aims to provide a packing material with good axial length adjustment performance, which is easy to adapt to packed towers of different sizes and thus has good versatility; another objective of the present invention is to provide a packed tower; and yet another objective of the present invention is to provide a preparation method.

[0006] Technical solution:

[0007] A packing material, comprising:

[0008] A plate corrugated packing assembly includes a plurality of corrugated plates connected in sequence, with adjacent corrugated plates staggered and a plurality of plate channels formed between adjacent corrugated plates;

[0009] The mesh corrugated packing assembly stacked with the plate corrugated packing assembly includes a plurality of corrugated meshes connected in sequence, with adjacent corrugated meshes staggered and a plurality of mesh channels formed between adjacent corrugated meshes;

[0010] The plate channel and the mesh channel are connected, and the number of plate channels is less than the number of mesh channels; the corrugation angle of the corrugated plate is less than the corrugation angle of the corrugated mesh, so as to increase the axial length adjustment range of the mesh corrugated packing assembly.

[0011] Specifically, in a type of packing of the present invention, the corrugation inclination angle refers to the angle between the corrugations and the vertical tower axis (vertical direction). The larger the corrugation inclination angle, the more the corrugations are biased towards the horizontal direction. Since the corrugation inclination angle of the corrugated plate is smaller than that of the corrugated mesh, it is equivalent to the corrugation inclination angle of the corrugated plate being relatively small and the corrugation inclination angle of the corrugated mesh being relatively large. This makes it easier for the corrugations of the corrugated mesh to be biased towards the horizontal direction, thereby facilitating the adjustment of the axial length of the corrugated mesh. This, in turn, facilitates the increase of the axial length adjustment range of the corrugated mesh, and ultimately facilitates the increase of the axial length adjustment range of the corrugated packing assembly, so as to better adapt to packed towers of different sizes.

[0012] Optionally, the mesh corrugated packing assembly further includes an elastic adjustment seat connected to one end of one of the corrugated meshes, the elastic adjustment seat and the plate corrugated packing assembly being stacked.

[0013] Optionally, the elastic adjustment seat includes:

[0014] First load-bearing plate;

[0015] Second bearing plate;

[0016] A corrugated elastic ring connecting the first support plate and the second support plate;

[0017] The first or second bearing plate and the plate corrugated filler assembly are stacked together.

[0018] Optionally, the elastic adjustment seat further includes a limiting rod that passes through the first support plate and the second support plate. One end of the limiting rod is threadedly connected to a first limiting block and a second limiting block at intervals. The first support plate is located between the first limiting block and the second limiting block. The other end of the limiting rod is threadedly connected to a third limiting block and a fourth limiting block at intervals. The second support plate is located between the third limiting block and the fourth limiting block.

[0019] Optionally, one side of the corrugated plate is provided with alternating front diversion protrusions and front guide grooves, and the other side of the corrugated plate is provided with a reverse diversion protrusion corresponding to the front guide groove, and a reverse guide groove corresponding to the front diversion protrusion.

[0020] Optionally, one side of the corrugated plate is further provided with a front connecting protrusion connected to the front diversion protrusion, and a front auxiliary flow channel communicating with the front guide channel. The other side of the corrugated plate is provided with a reverse connecting protrusion corresponding to the front auxiliary flow channel, and a reverse auxiliary flow channel corresponding to the front connecting protrusion. The reverse connecting protrusion and the reverse diversion protrusion are connected, and the reverse auxiliary flow channel and the reverse guide channel are communicating.

[0021] Optionally, the corrugated plate has a first through hole and a second through hole on its corrugations. The first through hole is located at the intersection of the outlet of the front guide channel and the outlet of the front auxiliary channel, and the second through hole is located at the intersection of the outlet of the reverse guide channel and the outlet of the reverse auxiliary channel.

[0022] Optionally, the front diversion protrusion and the front guide groove are both arc-shaped, so that the reverse guide groove and the reverse diversion protrusion are also arc-shaped.

[0023] A packed tower, comprising a packing material.

[0024] A preparation method for a filler, comprising:

[0025] The preparation of a corrugated plate packing assembly includes: rolling continuous corrugations on a plate roll at a preset corrugation angle, and stamping front diversion protrusions and front guide grooves to simultaneously form back guide grooves and back diversion protrusions; cutting the plate roll with the corrugations into single corrugated plates; bonding adjacent corrugated plates together with the corrugations in opposite directions to form several plate channels, and stacking them into a cylindrical plate packing disc blank; and fixing the cylindrical plate packing disc blank with a first circumferential belt.

[0026] The preparation of a corrugated mesh packing assembly includes: rolling continuous corrugations onto a mesh roll at a preset corrugation angle; cutting the mesh roll with the corrugations into single corrugated mesh pieces; bonding adjacent corrugated mesh pieces together with the corrugations in opposite directions to form several mesh channels, and stacking them into a cylindrical mesh packing disc blank; and fixing the cylindrical mesh packing disc blank with a second circling belt.

[0027] The plate corrugated packing assembly and the mesh corrugated packing assembly are stacked together.

[0028] Beneficial effects:

[0029] (1) In a packing of the present invention, the corrugation angle refers to the angle between the corrugation and the vertical tower axis (vertical direction). The larger the corrugation angle, the more the corrugation is biased towards the horizontal direction. Since the corrugation angle of the corrugated plate is smaller than that of the corrugated mesh, it is equivalent to the corrugation angle of the corrugated plate being relatively small and the corrugation angle of the corrugated mesh being relatively large. This makes it easier for the corrugation of the corrugated mesh to be biased towards the horizontal direction, thereby facilitating the adjustment of the axial length of the corrugated mesh, which in turn facilitates the increase of the axial length adjustment range of the corrugated mesh, and ultimately facilitates the increase of the axial length adjustment range of the corrugated packing assembly, so as to facilitate the adaptation to packing towers of different sizes.

[0030] (2) In a packing of the present invention, since the number of plate channels is less than the number of mesh channels, under the condition that the horizontal cross-sectional area of ​​the packing of the present invention is certain, it is easy to make the area of ​​a single plate channel larger than the area of ​​a single mesh channel. This makes it easier for the plate channels to carry a larger volume of air and liquid, accommodate material impurities and avoid blockage, and also makes it easier for the mesh channels to have a higher specific surface area. The initially clean medium after coarse separation by the lower plate corrugated packing assembly enters the mesh corrugated packing assembly and forms a uniform thin liquid film by relying on capillary action to achieve precise separation.

[0031] (3) In the packing of the present invention, since the number of plate channels is less than the number of mesh channels, under the condition that the horizontal cross-sectional area of ​​the packing of the present invention is certain, it is easy to make the plate channels and mesh channels interlaced rather than connected in a one-to-one correspondence. This makes it easier for gas and liquid to be split and dispersed into multiple mesh channels after flowing out from the single plate channel in the lower layer, forcing the gas and liquid to mix fully, disperse the flow, and the liquid phase to be re-uniformly filmed, suppressing the short circuit between the wall flow and the gas phase, and smoothly transitioning the pressure drop.

[0047] Example 1

[0048] like Figures 1-6 This embodiment provides a packing material, including: a plate corrugated packing assembly 1, comprising a plurality of corrugated plates 11 connected in sequence, adjacent corrugated plates 11 being staggered, and a plurality of plate channels 12 forming between adjacent corrugated plates 11; and a mesh corrugated packing assembly 2 stacked with the plate corrugated packing assembly 1, comprising a plurality of corrugated meshes 21 connected in sequence, adjacent corrugated meshes 21 being staggered, and a plurality of mesh channels 22 forming between adjacent corrugated meshes 21; wherein, the plate channels 12 and the mesh channels 22 are connected, the number of plate channels 12 is less than the number of mesh channels 22; the corrugation angle of the corrugated plates 11 is less than the corrugation angle of the corrugated meshes 21, so as to increase the axial length adjustment range of the mesh corrugated packing assembly 2.

[0049] Specifically, the plate corrugated packing assembly 1 has the advantages of high throughput, low separation precision, and anti-fouling. The corrugations of the corrugated plates 11 facilitate the formation of plate channels 12, thereby facilitating the flow of liquid and gas phases. Because adjacent corrugated plates 11 are staggered, i.e., the inclination directions of the corrugations of adjacent corrugated plates 11 are opposite, it facilitates forced gas-liquid multiple back-and-forth collisions, thereby increasing the gas-liquid contact area and suppressing wall flow, thus improving mass transfer separation efficiency. The corrugated plates 11 can be made of stainless steel, carbon steel, etc., and their thickness ranges from 0.15 to 0.4 mm. The mesh corrugated packing assembly 2 has the advantages of low throughput and high separation precision. The corrugations of the corrugated mesh 21 facilitate the formation of mesh channels 22, thereby facilitating the flow of liquid phases. In the gas phase, since adjacent corrugated meshes 21 are staggered, that is, the inclination direction of the corrugations of adjacent corrugated meshes 21 is opposite, it is convenient to force gas and liquid to fold and collide multiple times, thereby increasing the gas-liquid contact area and suppressing wall flow, thus improving mass transfer separation efficiency. The material of the corrugated meshes 21 can be stainless steel, titanium wire, etc., and the thickness of the corrugated meshes 21 is 0.1-0.3mm. The plate corrugated packing assembly 1 and the mesh corrugated packing assembly 2 are stacked together in the relevant packed tower 4, and the plate corrugated packing assembly 1 is preferably in the lower layer and the mesh corrugated packing assembly 2 is preferably in the upper layer. This not only makes it easy for the plate corrugated packing assembly 1 to provide good load-bearing effect on the mesh corrugated packing assembly 2, but also facilitates the gradual realization of coarse separation and fine separation.

[0050] Since the number of plate channels 12 is less than the number of mesh channels 22, under the condition that the horizontal cross-sectional area of ​​a packing material of the present invention is fixed, it is convenient to make the area of ​​a single plate channel 12 larger than the area of ​​a single mesh channel 22. This makes it convenient for the plate channels 12 to carry a larger gas-liquid flow, accommodate material impurities and avoid blockage, and also makes it convenient for the mesh channels 22 to have a higher specific surface area. The initially clean medium after coarse separation by the lower plate corrugated packing assembly 1 enters the mesh corrugated packing assembly 2, and forms a uniform thin liquid film by relying on capillary action to achieve precise separation. At the same time, since the number of plate channels 12 is less than the number of mesh channels 22, under the condition that the horizontal cross-sectional area of ​​a packing material of the present invention is fixed, it is convenient for the plate channels 12 and mesh channels 22 to be interconnected in an alternating manner rather than one-to-one. This makes it convenient for the gas and liquid to be split and dispersed into multiple mesh channels 22 after flowing out from the lower single plate channel 12, forcing the gas and liquid to be fully mixed, dispersed and deviated, and the liquid phase to be uniformly filmed again, suppressing the short circuit between the wall flow and the gas phase, and smoothly transitioning the pressure drop.

[0051] It should be noted that the corrugation inclination angle refers to the angle between the corrugations and the vertical tower axis (vertical direction). The larger the corrugation inclination angle, the more the corrugations are biased towards the horizontal direction. Since the corrugation inclination angle of the corrugated plate 11 is smaller than that of the corrugated mesh 21, it is equivalent to the corrugation inclination angle of the corrugated plate 11 being relatively smaller and the corrugation inclination angle of the corrugated mesh 21 being relatively larger. This makes it easier for the corrugations of the corrugated mesh 21 to be biased towards the horizontal direction, thereby facilitating the axial length adjustment of the corrugated mesh 21. This, in turn, facilitates increasing the axial length adjustment range of the corrugated mesh 21, and ultimately facilitates increasing the size of the corrugated packing assembly 2. The axial length adjustment range is adjusted to accommodate different sizes of packed tower 4. The preferred range of the corrugated mesh 21 corrugated inclination angle is 51°-57°. If the corrugated inclination angle is less than 51°, the corrugated slope is too steep, the vertical height of a single plate is large, which encroaches on the compensation stroke of the elastic adjustment seat 3, reduces the axial adjustable range, and the gas-liquid back-flow amplitude is insufficient, resulting in weak eddy current turbulence and reduced separation efficiency. If the corrugated inclination angle is greater than 57°, the corrugated slope is too gentle, the liquid phase is prone to concentrate and flow downward, causing wall flow and dry wall, the uniformity of gas-liquid distribution becomes poor, and the stability of the distillation operation is reduced.

[0052] Furthermore, such as Figures 1-2 The mesh corrugated packing assembly 2 also includes an elastic adjustment seat 3 connected to one end of a plurality of corrugated meshes 21, and the elastic adjustment seat 3 and the plate corrugated packing assembly 1 are stacked together.

[0053] Specifically, the elastic adjustment seat 3 is used to achieve elastic adjustment, which facilitates further increasing the axial length adjustment range of the corrugated packing assembly 2 to adapt to packing towers 4 of different sizes. The specific form of the elastic adjustment seat 3 can be a spring, a pleated elastic ring 33, etc.

[0054] Furthermore, such as Figure 2 The elastic adjustment seat 3 includes: a first support plate 31; a second support plate 32; and a corrugated elastic ring 33 connected between the first support plate 31 and the second support plate 32; wherein the first support plate 31 or the second support plate 32 and the corrugated packing assembly 1 are stacked.

[0055] Specifically, the first support plate 31 and the second support plate 32 are used to jointly support the corrugated elastic ring 33, and the plate corrugated packing assembly 1 is used to connect with the first support plate 31 or the second support plate 32, so as to facilitate the up-and-down adjustable installation of the elastic adjustment seat 3, ensure high installation error tolerance, and good installation convenience. In order to facilitate the flow of liquid and gas phases, the first support plate 31 and the second support plate 32 are both annular plates. At the same time, in order to facilitate the redistribution of liquid phase, the elastic adjustment seat 3 has a distributor, which is connected to the first support plate 31 or the second support plate 32. The type of distributor is preferably a disc sieve distributor. The corrugated elastic ring 33 helps to ensure the good sealing of the elastic adjustment seat 3, thereby facilitating the prevention of the gas and liquid in the packed tower 4 from forming a bypass short-circuit flow between the outer ring of the elastic adjustment seat 3 and the tower wall and the packing frame. At the same time, it can prevent the liquid phase from accumulating in the interlayer gaps and generating wall flow, and ensure that the uniformity of liquid and gas distribution of the distributor is not affected by the bypass fluid. The corrugated elastic ring 33 can be in the form of a V-shaped corrugated ring, a U-shaped corrugated ring, etc.

[0056] Furthermore, such as Figure 2 The elastic adjustment seat 3 also includes a limiting rod 34 that passes through the first bearing plate 31 and the second bearing plate 32. One end of the limiting rod 34 is threadedly connected to the first limiting block 351 and the second limiting block 352 at intervals. The first bearing plate 31 is located between the first limiting block 351 and the second limiting block 352. The other end of the limiting rod 34 is threadedly connected to the third limiting block 353 and the fourth limiting block 354 at intervals. The second bearing plate 32 is located between the third limiting block 353 and the fourth limiting block 354.

[0057] Specifically, the limiting rod 34, in conjunction with four limiting blocks, facilitates the limitation of the adjustment range of the pleated elastic ring 33, preventing over-adjustment or under-adjustment. The distance between the first limiting block 351 and the second limiting block 352 is preferably greater than the thickness of the first bearing plate 31, and the distance between the third limiting block 353 and the fourth limiting block 354 is preferably greater than the thickness of the second bearing plate 32. Preferably, there are three limiting rods 34, and the three limiting rods 34 are preferably evenly distributed along the circumference of the first bearing plate 31 or the second bearing plate 32 to ensure good uniformity of force distribution. At the same time, it is necessary to ensure that one limiting rod 34 corresponds to four limiting blocks.

[0058] Furthermore, such as Figures 7-9 The corrugated plate 11 has a front diversion protrusion 111 and a front guide groove 112 interlaced on one side of the corrugations, and a reverse diversion protrusion 113 corresponding to the front guide groove 112 and a reverse guide groove 114 corresponding to the front diversion protrusion 111 on the other side of the corrugations.

[0059] Specifically, the front diversion protrusion 111 and the back diversion protrusion 113 are used to cut and disperse the concentrated gas and liquid phases, preventing the gas phase from flowing directly into the channel and causing deviation. They force the gas phase to disperse in the guide channel, and at the same time, a liquid film is attached to the surface of the diversion protrusion, increasing the gas-liquid contact area. The front guide channel 112 and the back guide channel 114 are used to receive the gas and liquid after being diverted by the diversion protrusion, constrain the fluid to flow orderly along the corrugations, gather the dispersed liquid phase, and inhibit the liquid phase from forming wall flow along the tower wall. At the same time, a low-speed swirling flow is formed in the guide channel, which prolongs the contact residence time of the gas and liquid phases and improves the mass transfer efficiency. Because the diversion protrusions and guide channels are staggered, the gas and liquid flow repeatedly complete the cycle of "diversion protrusions to disperse and divert - guide channels to regulate and guide" when passing through, eliminating the concentrated short circuit of fluid in the plate channel 12, making the gas and liquid mix more uniform, reducing the overall pressure drop of the tower, and simultaneously enhancing the mass transfer and separation capacity.

[0060] Furthermore, such as Figures 10-12 The corrugated plate 11 has a front connecting protrusion 115 connected to the front diversion protrusion 111 and a front auxiliary flow channel 116 connected to the front guide channel 112 on one side of the corrugations. The corrugated plate 11 has a reverse connecting protrusion 117 corresponding to the front auxiliary flow channel 116 and a reverse auxiliary flow channel 118 corresponding to the front connecting protrusion 115. The reverse connecting protrusion 117 is connected to the reverse diversion protrusion 113, and the reverse auxiliary flow channel 118 is connected to the reverse guide channel 114.

[0061] Specifically, the connecting protrusions facilitate further cutting and dispersing of the concentrated gas and liquid phases, preventing the gas phase from flowing directly into the guide channel and forcing the gas phase to disperse. At the same time, the surface of the diversion protrusions is coated with a liquid film, increasing the gas-liquid contact area. The outlet of the auxiliary channel and the connection point of the guide channel facilitate the formation of vortices. The vortices generate local low-pressure backflow zones, and a small amount of liquid phase flows back, prolonging the contact residence time of the gas and liquid phases and improving separation efficiency. Meanwhile, the backflow vortex continuously washes the inner walls of the auxiliary channel and guide channel, preventing impurities and polymers from depositing in dead corners within the channel and improving anti-clogging ability. Furthermore, the vortex facilitates the dispersal of large liquid clumps, dividing the liquid phase into thin liquid films, ensuring that the entire plate surface is wetted even under low spray loads, with no dry wall areas. The front connecting protrusion 115 and the front auxiliary channel 116 are preferably processed by one-piece stamping, which facilitates the simultaneous formation of the reverse auxiliary channel 118 and the reverse connecting protrusion 117.

[0062] Furthermore, such as Figures 10-12 The corrugated plate 11 has a first through hole 1191 and a second through hole 1192 on its corrugations. The first through hole 1191 is located at the intersection of the outlets of the front guide channel 112 and the front auxiliary channel 116, and the second through hole 1192 is located at the intersection of the outlets of the reverse guide channel 114 and the reverse auxiliary channel 118.

[0063] Specifically, a vortex is generated at the intersection of the outlets of the front guide channel 112 and the front auxiliary channel 116. This is equivalent to the first through hole 1191 being located in the area where the vortex is generated, which facilitates the opening of the positive and negative flow channels of the corrugated plate 11. The vortex can shuttle in both directions, resulting in more thorough gas-liquid mixing and improved separation efficiency. At the same time, it is convenient to release the local pressure build-up of the vortex and reduce the overall pressure drop of the packing. Furthermore, impurities carried by the vortex can pass through the first through hole 1191 and be carried away by the airflow, making it less prone to scale buildup and blockage. The shape of the first through hole 1191 is preferably circular, and the aperture range of the first through hole 1191 is preferably 2-5mm. If the aperture of the first through hole 1191 is too large, it is easy for the gas phase to directly short-circuit through, weakening the guiding and diverting effect of the channel. If the aperture of the first through hole 1191 is too small, it is easy to be blocked by impurities. The number of first through holes 1191 is not limited, but is preferably 1-3. The effect and constraint of the second through hole 1192 are similar to those of the first through hole 1191, and will not be described in detail here.

[0064] Furthermore, such as Figures 7-9 The front diversion protrusion 111 and the front guide groove 112 are both arc-shaped, so that the reverse guide groove 114 and the reverse diversion protrusion 113 are also arc-shaped.

[0065] Specifically, the front diversion protrusion 111 and the front guide groove 112 are preferably arc-shaped to reduce fluid resistance, prevent clogging, and maintain an intact liquid film. The front diversion protrusion 111 and the front guide groove 112 are preferably integrally formed by stamping, which facilitates the simultaneous formation of the reverse guide groove 114 and the reverse diversion protrusion 113, and also makes it easy for the reverse guide groove 114 and the reverse diversion protrusion 113 to also be arc-shaped.

[0066] like Figure 1 This embodiment also provides a packed tower, including a packing material of this embodiment.

[0067] like Figure 1This embodiment also provides a preparation method for a filler used in this embodiment, including: preparing a plate corrugated filler assembly 1, including: rolling continuous corrugations on a plate roll at a preset corrugation angle, and stamping a front diversion protrusion 111 and a front guide groove 112 to simultaneously form a reverse guide groove 114 and a reverse diversion protrusion 113; cutting the corrugated plate roll into single corrugated plates 11; bonding two adjacent corrugated plates 11 together with the corrugations in opposite directions to form several plate channels 12, and stacking them into a cylindrical plate filler disc blank; fixing the cylindrical plate filler disc blank with a first circling belt. The preparation of the corrugated mesh packing assembly 2 includes: rolling continuous corrugations onto a mesh roll at a preset corrugation angle; cutting the corrugated mesh roll into individual corrugated mesh pieces 21; bonding adjacent corrugated mesh pieces 21 together with opposite corrugations to form several mesh channels 22, and stacking them into a cylindrical mesh packing disc blank; fixing the cylindrical mesh packing disc blank with a second circling belt. The plate corrugated packing assembly 1 and the mesh corrugated packing assembly 2 are then stacked together.

[0068] Specifically, the preparation of the plate corrugated packing assembly 1 also includes degreasing, pickling, rust removal, and drying of the plate roll to ensure the cleanliness of the plate roll and thus ensure the preparation accuracy of the plate corrugated packing assembly 1. After cutting into individual corrugated plates 11, the sharp edges of the corrugated plates 11 need to be ground and the orifices rounded to avoid cuts and liquid accumulation. After the cylindrical plate packing disc blank is fixed with the first surrounding belt, the whole thing needs to be passivated, cleaned, and dried, and the corrugation angle, plate bonding gap, and outer diameter dimensions need to be tested to obtain the complete plate corrugated packing assembly 1.

[0069] The preparation of the corrugated mesh packing assembly 2 also includes degreasing and cleaning the mesh roll to remove oil and impurities, and drying it to ensure the cleanliness of the mesh roll and thus ensure the preparation accuracy of the corrugated mesh packing assembly 2. After cutting it into individual corrugated mesh 21 pieces, the edges and corners of the corrugated mesh 21 need to be rounded to remove burrs and avoid cuts and liquid accumulation. After the cylindrical mesh packing disc blank is fixed with a second wrapping belt, the whole thing needs to be pickled and passivated, rinsed with clean water and dried, and the aperture, inclination angle and flatness need to be inspected to obtain the complete corrugated mesh packing assembly 2.

[0070] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
