Description

Technical Field

[0001] The present invention relates to a gas treatment device, and further to a gas treatment device for treating organic waste gas pollutants by using a catalytic method or an adsorption concentration method. Background Art

[0002] In the invention patent application with publication number CN115487641A and titled "Rotary Docking Matrix Gas Treatment Device" filed by the applicant of the present application on March 26, 2022, a gas treatment device consisting of a plurality of parallel adsorption units and a set of mobile hot air regeneration devices is disclosed. The main functional structure of the gas treatment device includes: a shell, a working gas input distribution chamber, a plurality of parallel working units, a working gas output collection chamber and a set of rotating regeneration devices. The parallel working units are arranged in a matrix, and the respective gas inlets and outlets are arranged into a plane ring or further uniformly arranged into a ring array in the working gas input distribution chamber and the working gas output collection chamber through the connecting pipelines on both sides. During the adsorption or catalytic process, the working gas entering the working gas input distribution chamber passes through the parallel working units to reach the working gas output collection chamber. During the regeneration process, the rotating regeneration device uses high-temperature gas to complete the connection and switching between the regeneration device and each working unit group through the disengagement, rotation and docking actions, heats and regenerates the working units one by one, and outputs the regenerated gas to the outside of the device through the pipeline.

[0003] However, there are still aspects that need to be improved in the gas treatment device. For example, the gas treatment device arranges the inlet and outlet of the working unit into a plane ring through a connecting pipeline, which limits the caliber size of the inlet and outlet of the working unit, resulting in the fact that during the adsorption or catalytic process, the working gas must pass through the inlet and outlet of the working unit with the connecting pipeline at a higher gas flow rate. According to the principles of fluid mechanics, the inlet and outlet of the gas pipeline directly opening in the unrestricted space will produce great wind resistance. In order to significantly reduce the wind resistance, the inventor of the present application envisions setting a flaring structure at the inlet and outlet of the gas pipeline, such as a flaring structure similar to a trumpet shape. However, the inlet and outlet of the working unit arranged in a plane ring will be limited by the space of the plane ring, and the setting of the rotary regeneration device will also have specific requirements for the docking space. These constraints or restrictions are all in conflict with the space required for setting a flaring structure separately for the inlet and outlet of each working unit in a conventional manner.

[0004] Therefore, there is an urgent need to provide an improved gas processing device that can overcome one or more disadvantages of the above-mentioned rotary docking matrix gas processing device. Summary of the invention

[0005] The object of the present invention is to provide a gas processing device, which has made technical improvements on the gas processing devices of the prior art, can optimize the arrangement of the inlet and outlet of each working unit, and in the process solve the technical problem of excessive wind resistance when the working gas passes through the inlet and outlet of the working unit with connecting pipelines at a higher gas flow rate.

[0006] According to one aspect of the present invention, a gas processing device is proposed, which may include: a shell; a working gas input distribution chamber and a working gas output collecting chamber, wherein the working gas output collecting chamber may be arranged downstream of the working gas input distribution chamber in the direction of the gas flow; a plurality of working units, wherein the plurality of working units may be arranged in an array, wherein each working unit is connected between a corresponding inlet pipeline and an outlet pipeline, connecting the working gas input distribution chamber and the working gas output collecting chamber, wherein the inlets of the inlet pipelines are arranged in an inlet annular array, and the outlets of the outlet pipelines are arranged in an outlet annular array; and a guide port device, wherein the guide port device may be arranged at the inlet annular array and / or the outlet annular array, wherein the guide port device may include an opening groove extending at least partially in the circumferential direction, and the opening profile of the opening groove may taper toward the working unit.

[0007] In the gas processing device of the present invention, a balance is achieved between the inlet of the inlet pipeline or the outlet of the outlet pipeline and the arrangement of the guide port device within a limited space, and the wind resistance at the pipeline inlet or outlet of the working gas is effectively reduced through the tapered shape of the opening groove, thereby significantly increasing the flow rate of the working gas through the working unit.

[0008] According to the above aspects of the present invention, preferably, the guide port device can be arranged at the inlet annular array and the outlet annular array, and the guide port device is formed as an annular bell mouth in the circumferential direction. In this way, the wind resistance at the inlet and outlet of the pipeline of the working gas can be further reduced. Based on the experimental comparison of the inventor, under the condition that the parameters of the blower and other components outside the device, the working unit and the pipeline and other components inside the device are the same, the gas processing device according to the present invention can increase the flow rate of the working gas processed per unit time by about 10-20%, greatly improving the gas processing efficiency.

[0009] According to the above-mentioned aspects of the present invention, preferably, the annular bell mouth can be an annular groove with a polyhedron or a rotating body profile, the annular groove having a first end and an opposite second end and a first side wall and a second side wall extending between the first end and the second end, wherein the first end is open, and the second end, the first side wall or one of the second side walls is provided with an array of openings arranged circumferentially, and each opening in the opening array is aligned with the inlet of the inlet annular array or the outlet of the outlet annular array.

[0010] In order to reduce the manufacturing difficulty and cost, the annular bell mouth can be formed as: a trapezoid or convex quadrilateral with a first end (i.e., short side) having a diameter roughly the same as that of the connecting pipe of the working unit, an annular rotating body formed by rotating along the axis of the annular array of the inlet and outlet of the working unit, an annular groove of the rotating body formed by removing a surface from the rotating body, and the inlet and outlet of the working unit can be opened on the groove bottom plane (i.e., the bottom surface of the first end). If the annular groove is formed by rotating a trapezoid, the inner and outer edges of the annular groove are flush. If the inner and outer edges of the annular groove are not flush, it is formed by rotating a non-trapezoidal quadrilateral.

[0011] According to the above aspects of the present invention, preferably, the opening array can be arranged on the second side wall, and the inlet of the inlet pipeline and the outlet of the outlet pipeline each have a shape with a tapered opening size, so that the opening size of the inlet and the outlet tapers toward the working unit. The tapered shape can be, for example, a linear tapered shape of a trapezoid or a roughly trapezoidal shape, or a shape that tapers in a roughly curved (e.g., parabolic) shape. This arrangement can expand the effective area available for the inlet and outlet arrangement. If the second end of the annular groove tapers to zero, the cross-sectional shape of the annular groove can be approximately V-shaped at this time.

[0012] According to the above aspect of the present invention, preferably, the opening array can be arranged at the second end, and the ratio of the width of the second end to the inner diameter of the inlet and the inner diameter of the outlet is in the range of 1.0-1.1. In this way, the width of the second end is substantially equal to the opening size of the inlet and outlet matched therewith. This arrangement forms a smooth transition between the inlet and outlet of the working unit and the annular bell mouth, minimizes the formation of local vortices, and further reduces wind resistance.

[0013] According to the above aspect of the present invention, preferably, a partition can be provided between adjacent openings of the opening array. The partition can be used to guide the airflow of the working gas and fill the airflow dead corner space of the space. This arrangement also forms a smooth transition between the inlet and outlet of the working unit and the annular bell mouth, avoiding the formation of local vortices, thereby further reducing wind resistance.

[0014] According to the above aspect of the present invention, preferably, the first side wall of the annular groove can extend in a direction away from the second end to form a tapered flow-guiding structure. For example, the annular curved surface of the first side (i.e., the inner side) of the annular groove can be directly extended or gradually reduced to form a conical (or pyramidal), multi-segmented conical or smooth curved conical flow-guiding structure, which can utilize limited space and use less material to increase the effective area of ​​the annular bell mouth to the maximum, and can further significantly reduce wind resistance.

[0015] According to the above aspect of the present invention, preferably, the second side wall of the annular groove can be connected with the air inlet pipe (or inlet pipeline) of the working gas and the air outlet pipe (or outlet pipeline) of the working gas, so that the inner space of the annular bell mouth forms a corresponding working gas input distribution chamber and a working gas output collection chamber. In this way, the volume of the working gas input distribution chamber and the working gas output collection chamber can be reduced, thereby improving the space utilization rate, and the kinetic energy of the airflow in the air duct can be effectively utilized, thereby further reducing the wind resistance of the entire pipeline system.

[0016] According to the above aspect of the present invention, preferably, at least one of the first side wall and the second side wall of the annular bell mouth connected to the inlet of the inlet pipeline is arranged so that the tangent of the circumferential outer edge is orthogonal to the airflow direction (it should be noted that the airflow direction here is the macroscopic airflow direction of the working gas). Through this arrangement, an arc-shaped tapered bell mouth is formed, and with the help of the arc-shaped circumferential edge, the wind resistance of the inlet of the inlet pipeline can be better reduced.

[0017] According to the above aspects of the present invention, in order to further improve the guiding effect on the airflow and further reduce the vortex, preferably, the annular bell mouth can be set to a petal shape corresponding to the inlet of the inlet pipe and the outlet of the outlet pipe.

[0018] According to the above aspects of the present invention, preferably, the gas processing device may also include a rotary regeneration device, which can be used to regenerate the adsorbent or catalyst in the working unit, wherein the gas processing device can be used for a working gas processing process and a regeneration process, and during the working gas processing process, the working gas entering the working gas input distribution chamber passes through a plurality of working units to reach the working gas output collection chamber, and during the regeneration process, the rotary regeneration device uses high-temperature gas to heat and regenerate the working units in the plurality of working units one by one, recovers the heating heat energy, and outputs the regenerated gas to the outside of the gas processing device through a pipeline, wherein the rotary regeneration device completes the connection and switching with the regeneration working unit group through detachment, rotation and docking actions, and the regeneration working unit group includes at least one regeneration working unit and at least one regeneration heat recovery working unit.

[0019] Through this arrangement, the exhaust gas concentration ratio of the gas treatment device during the regeneration process can be increased, while the heat utilization efficiency is improved.

[0020] According to the above aspect of the present invention, preferably, the guide port device of the gas processing device can rotate synchronously with the rotary regeneration device, so that the rotary regeneration device can occupy part of the side wall space of the bell mouth without affecting the ideal structure of the entire annular bell mouth to reduce wind resistance.

[0021] According to the above aspect of the present invention, when the annular bell mouth is configured to rotate synchronously with the rotary regeneration device, if the gas treatment device is used in a manner that the working gas treatment and heating regeneration are performed simultaneously, then the inlet and outlet of the working unit combined with the rotary regeneration device do not need to reduce the wind resistance of the gas treatment process, and thus the corresponding part of the annular bell mouth structure can be omitted. Therefore, preferably, the gas treatment device can simultaneously perform the working gas treatment process and the regeneration process, and the profile of the guide port device has one or more notches in the circumferential direction.

[0022] Therefore, the gas processing device of the present invention meets the predetermined performance requirements, overcomes the shortcomings of the prior art and achieves the predetermined purpose of the invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0081] It should be understood that, unless expressly stated otherwise, the present invention may adopt various alternative orientations and step sequences. It should also be understood that the specific devices shown in the drawings and described in the specification are merely exemplary embodiments of the inventive concepts disclosed and defined herein. Therefore, unless otherwise expressly stated, the specific orientations, directions or other physical characteristics of the various embodiments disclosed should not be considered as limiting.

[0082] Example 1 :

[0083] Figure 1A shows a schematic perspective view of a gas processing device 100 according to a first non-limiting embodiment of the present invention; Figure 1B Shown in Figure 1A Schematic diagram of the gas processing device 100 observed at the schematic section AA.

[0084] As shown and as a non-limiting example, the gas processing device 100 may mainly include: a housing 10 , a working gas input distribution chamber 20 , a working gas output collection chamber 30 , a plurality of working units 40 , a guide port device 50 and a rotary regeneration device 60 .

[0085] The housing 10 may be used to carry and accommodate at least a portion of the components of the gas processing device 100. Figure 1B In the illustrated embodiment, the housing 10 can be divided into two chambers via a chamber partition 10A, for example, a working gas input distribution chamber 20 located on the left and a working gas output collection chamber 30 located on the right. Figure 1B The chamber partition 10A is schematically shown in the form of a vertical dividing line arranged at the middle position of the housing 10. However, it should be understood that the chamber partition 10A can adopt any suitable structure as long as it physically separates the working gas input distribution chamber 20 and the working gas output collection chamber 30 and can withstand the pressure difference therebetween. For example, the chamber partition 10A can be in the form of a metal plate, which is welded, glued or otherwise fixed to the inner wall of the housing 10.

[0086] like Figure 1B As shown in FIG. 1 , the working gas input distribution chamber 20 may have a working gas inlet 11 to allow the working gas to enter the working gas input distribution chamber 20. As used herein, "working gas" may refer to polluted gas, harmful gas, waste gas, etc., which need to be adsorbed or catalytically treated.

[0087] The working gas output collection chamber 30 may be arranged downstream of the working gas input distribution chamber 20 in the working gas flow direction F, and has a working gas outlet 12 for discharging the processed gas out of the gas processing device 100 .

[0088] It should be understood that the description "gas flow direction" as used herein refers to the macroscopic flow direction of the working gas from the working gas input distribution chamber 20 toward the working gas output collection chamber 30, rather than the movement direction in each component. Figure 1A and 1B In the embodiment, the airflow direction F may be substantially parallel to or coincident with the center line X of the array of working units 40. A plurality of working units (or processing units) 40 may be arranged in an array, for example Figure 1A and 1B In the embodiment shown in the accompanying drawings, the plurality of working units 40 may include 24 working units 40, and form a matrix of 5 rows and 5 columns, wherein no working unit 40 is arranged at the middle position, such as Figure 1B However, it should be understood that those skilled in the art may alternatively arrange it into other types of array forms, such as one or more rows, adjacent working units 40 aligned or not aligned, etc., without departing from the scope of the present invention.

[0089] Each working unit 40 may have an internal space, in which a working medium (or treatment medium) 401 may be disposed. The working medium 401 may include, for example, an adsorbent and / or a catalyst, which may divide the internal space into a first working space 410 and a second working space 420 .

[0090] The first working space 410 can be connected to the working gas input distribution chamber 20, and the second working space 420 can be connected to the working gas output collection chamber 30. The working gas from the working gas input distribution chamber 20 can pass through the working medium 401 into the working gas output collection chamber 30, and undergo an adsorption and / or catalytic treatment process in the process.

[0091] exist Figure 1A and 1B In the illustrated embodiment, the first working space 410 can be connected to the working gas input distribution chamber 20 via the inlet pipe 41, and the second working space 420 can be connected to the working gas output collection chamber 30 via the outlet pipe 42. In this way, the working unit 40 is connected between the corresponding inlet pipe 41 and the outlet pipe 42, and the working unit 40 communicates the working gas input distribution chamber 20 and the working gas output collection chamber 30.

[0092] like Figure 1AAs shown in FIG. 1 , each inlet pipe 41 and each outlet pipe 42 can be guided (e.g., bent) toward the center line X of the array of working units 40 so that the inlets 41A of the inlet pipes 41 are arranged into an inlet annular array 40A, and the outlets 42A of the outlet pipes 42 are arranged into an outlet annular array 40B.

[0093] In the inlet annular array 40A, each inlet 41A can be arranged equidistantly in the circumferential direction C and formed on a substantially circular contour, and similarly, in the outlet annular array 40B, each outlet 42A can be arranged equidistantly in the circumferential direction C and formed on a substantially circular contour.

[0094] It should be understood that although the inlet annular array 40A and the outlet annular array 40B are shown as being located in a first plane, that is, each inlet 41A is located in the same plane, and each outlet 42A is shown as being located in a second plane, the second plane may be parallel to the first plane. However, in an alternative embodiment, the inlet annular array 40A and the outlet annular array 40B may also exist in a corresponding rotational curved surface or a rotational body space, and may be located in planes that are not parallel to each other, without limitation.

[0095] According to the present invention, in order to reduce the wind resistance at the inlet or outlet of the gas pipeline, for example, the inlet pipeline 41 and / or the outlet pipeline 42, increase the flow rate of the working gas passing through the working unit 40, and thereby improve the processing efficiency of the gas processing device 100 and reduce energy consumption, a guide port device 50 can be provided at the inlet annular array 40A and / or the outlet annular array 40B.

[0096] exist Figure 1A and 1B In the illustrated embodiment, the guide port device 50 is provided at both the inlet annular array 40A and the outlet annular array 40B. However, in alternative embodiments, the guide port device 50 may be provided only at the inlet annular array 40A, or only at the outlet annular array 40B. In addition, in the embodiment where the guide port device 50 is provided at both the inlet annular array 40A and the outlet annular array 40B, the first guide port device 510 provided at the inlet annular array 40A may be the same as or different from the second guide port device 520 provided at the outlet annular array 40B.

[0097] As shown in the figure, the guide mouth device 50 can be in the form of an open groove, for example, an open groove extending in the circumferential direction C, which can extend continuously in the circumferential direction C into the form of a complete annular open groove, or alternatively, the contour of the guide mouth device 50 can have one or more notches in the circumferential direction C, as will be described in more detail below.

[0098] The opening profile of the opening slot may be gradually reduced toward the working unit 40, that is, Figure 1A and 1B In the embodiment shown in , the opening slot on the left side tapers toward the right side (ie, the opening on the left side is larger than the opening on the right side), while the opening slot on the right side may taper toward the left side (ie, the opening on the right side is larger than the opening on the left side).

[0099] Figure 1A The open slot shown in the figure can be similar to an annular bell mouth in shape, and the annular bell mouth can be an annular slot with a polyhedron or a rotating body profile. For example, the annular slot can have a first end 51 and an opposite second end 52 and a first side wall 53 and a second side wall 54 extending between the first end 51 and the second end 52.

[0100] The first end 51 may be an open end with a larger size, that is, the first end 51 is open, and the second end 52 may be a bottom wall with a smaller size, and openings may be provided on the bottom wall to form a circumferentially arranged opening array 55. Each opening in the opening array 55 may be aligned with the inlet 41A of the inlet annular array 40A or the outlet 42A of the outlet annular array 40B.

[0101] As an example, the ratio of the width of the second end 52 to the inner diameter (or opening size) of the inlet 41A and the inner diameter (opening size) of the outlet 42A is respectively in the range of 1.0-1.1, that is, the opening sizes of the inlet 41A and the outlet 42A are basically equal to the width of the second end of the annular bell mouth at this position, and the width dimension can be the dimension measured in the radial direction R.

[0102] In addition, in the embodiment where the opening array 55 is disposed at the second end 52, the diameter of each opening in the opening array 55 of the annular bell mouth at the second end 52 may be substantially equal to the opening size of the inlet 41A or the outlet 42A at its installation location.

[0103] In addition, it should be understood that, although in the embodiment shown in conjunction with the drawings, each opening in the opening array 55, the inlet 41A of the inlet annular array 40A, and the outlet 42A of the outlet annular array 40B are shown as circular openings, it should be understood that the opening shape is only schematic, and the present invention is not limited thereto, and those skilled in the art can envision a substantially square, rectangular or polygonal opening form, and the shapes or sizes of the openings in an opening array 55 can also be different, at least the openings can be matched or corresponded to each other at the joints.

[0104] exist Figure 1BIn the illustrated embodiment, the size (e.g., diameter) of each opening in the opening array 55 may be larger than the size (e.g., diameter) of the opening of the inlet 41A or the size (e.g., diameter) of the opening of the outlet 42A, thereby allowing the guide port device 50 to be sleeved on the outside of the inlet 41A and the outlet 42A at the opening array 55, and forming an overlapped portion at the sleeved portion. In addition, preferably, a corresponding sealing structure may be provided at the overlapped portion to reduce air leakage. In this embodiment, the guide port device 50 may not rotate relative to the rotating regeneration device 60.

[0105] In embodiments where the dimension of the second end 52 is zero, the open slot may have a V-shaped cross-section, ie, a V-shaped cross-section viewed along a section through the centerline X. As shown in FIG.

[0106] The first side wall 53 and the second side wall 54 may extend between the first end 51 and the second end 52, respectively. Figure 1A and 1B In the embodiment shown in FIG. 5 , the first side wall 53 may be an inner side wall closer to the center line X, and the second side wall 54 may be an outer side wall farther from the center line X. The first side wall 53 and the second side wall 54 may be formed in a smooth or zigzag (stepped) shape, and may include various flat or curved profiles, and instead of the opening array on the second end 52, an opening array may also be provided on one of the first side wall 53 and the second side wall 54, as will be exemplarily described below.

[0107] As an example, for the purpose of reducing manufacturing difficulty and cost, the annular bell mouth can be a trapezoid or a convex quadrilateral whose second end 52 (i.e., the short side) is roughly the same as the diameter of the working unit connecting pipe (i.e., the opening size of the inlet 41A or the opening size of the outlet 42A), and the annular rotating body formed by rotating along the center line X of the inlet annular array 40A or the outlet annular array 40B of the working unit 40 is removed by drawing a shell to form an annular groove in the shape of a rotating body or a polyhedron. The inlet 41A of the inlet pipeline 41 and the outlet 42A of the outlet pipeline 42 can be formed on the bottom plane of the groove. In an embodiment formed by rotating a trapezoid, the first side wall 53 and the second side wall 54 of the annular groove can be flush with each other. In an embodiment formed by rotating a non-trapezoidal quadrilateral, the first side wall 53 and the second side wall 54 of the annular groove can also be uneven.

[0108] It should be understood that the rotation in "rotation by a trapezoid" and "rotation by a non-trapezoidal quadrilateral" as used in this article may refer to a rotating body formed by continuous rotation, that is, the side wall is a smooth curved surface, and may also refer to a polyhedron formed by discontinuous rotation, that is, the side wall is a polyhedron formed by splicing multiple trapezoids or quadrilaterals.

[0109] The gas treatment device 100 can be used in a working gas treatment process, for example, for an adsorption and / or catalytic process with the aid of a working medium 401. In this process, the working gas entering the working gas input distribution chamber 20 via the working gas inlet 11 first reaches the guide port device 50, enters the inner space of the annular bell mouth via the opening at the first end 51 of the guide port device 50, and is guided along the first side wall 53 and the second side wall 54, and then enters the inlet 41A of the inlet pipe 41 via the opening at the second end 52. Next, the working gas enters the first working space 410 of the working unit along the inlet pipe 41, passes through the adsorbent and / or catalyst contained therein, reaches the second working space 420, and enters the working gas output collection chamber 30 via the outlet 42A of the outlet pipe 42. The exemplary working gas travel path is shown in FIG. Figure 1B It is schematically shown by hollow arrows.

[0110] like Figure 1B As schematically shown in FIG. 1 , the gas processing device 100 may further include a rotary regeneration device 60 for use in the regeneration process.

The specific structure and working principle of the rotary regeneration device 60 may refer to the contents disclosed in the invention patent application with publication number CN115487641A submitted by the applicant of the present application, the entire text of which is incorporated herein by reference, as if re-described in the present application.

[0111] During the regeneration process, the rotating regeneration device 60 can use high-temperature gas to complete the connection and switching with the regeneration working unit group through detachment, rotation and docking actions, heat and regenerate one or more (for example, two or four) of the multiple working units 40 one by one, recover the heating heat energy, and output the regenerated gas to the outside of the gas treatment device 100 through a pipeline. Figure 1B An example path of high temperature gas is schematically shown by a single arrow. The regeneration working unit group may include at least one regeneration working unit and at least one heat recovery working unit. The high temperature gas may be, for example, a heated gas having a temperature in the range of 100° C. to 600° C., such as heated air, etc. The high temperature gas may also be referred to as a desorption gas.

[0112] For example, two shunt connection joints 66 of the rotating regeneration device 60 may be provided, and the shunt connection joints 66 may be matched to two adjacent openings of the opening array 55 to allow the high-temperature gas to enter or leave the corresponding working unit 40 through the two openings. In addition, the shunt connection joint 66 may be rotated in the circumferential direction C to switch to another group of openings of the opening array 55.

[0113] It should be noted that in order to better illustrate the principle of the present invention, Figure 1A Only two branch connection joints 66 of the rotary regeneration device 60 corresponding to the inlet 41A of the working unit 40 in the annular bell mouth are shown, and the connecting pipeline device and the mechanical drive device are omitted. The subsequent embodiments are also handled in the same way and will not be explained separately later.

[0114] In addition, it should be noted that Figure 1B The branch connection joint 66 of the rotating regeneration device 60 should be connected to two adjacent openings of the opening array 55 (such as Figure 1A However, in order to facilitate a more intuitive expression of the gas flow direction, Figure 1B The schematic diagram shows that the branch connection joint 66 is respectively connected to the two sides of the rotation center line X (i.e. Figure 1B The two openings (on the upper side and the lower side) are connected respectively, and the following embodiments are also handled in this way, and will not be explained separately later.

[0115] Likewise, it should be understood that although Figure 1B The center branch connection joint 66 and the annular bell mouth are shown as being spaced apart, but it should be understood that this is to more clearly illustrate their arrangement position. During use, they can fit tightly together with no gap or only a small gap between them.

The purpose of providing the partition 55A is to form a smooth transition between the inlet 41A, the outlet 42A and the annular bell mouth of the working unit 40, to avoid local vortex formation, thereby further reducing wind resistance.

[0130] As an example, the partition 55A may be positioned such that its extension line in the radial direction R passes through the center of the annular bell mouth, and its bottom is fixed to the second end 52 of the annular groove, its sides are respectively fixed to the first side wall 53 and the second side wall 54, and its free end opposite to the bottom may be flush with the circumferential outer edge 511. As a preferred embodiment, the partition 55A may have a substantially tapered cross section such that the thickness of its bottom is greater than the thickness of its free end, so as to guide the airflow more smoothly.

[0133] The fifth embodiment of the gas processing device 100 is similar to Figure 1A and 1B The first embodiment of the gas processing device 100 is shown, and the same or similar elements are generally indicated herein with the same or similar reference numerals and may not be re-introduced hereinafter.

[0134] exist Figure 5A and 5B In the illustrated embodiment, the first side wall 53 of the annular groove extends in a direction away from the second end 52 to form a tapered flow guide structure 530, thereby better guiding the flow of the working gas and further reducing wind resistance. In addition, in this embodiment, the gas processing device 100 is provided with two chamber partitions 10A, and the two chamber partitions 10A sandwich the array of multiple working units 40 therebetween.

[0138] The sixth embodiment of the gas processing device 100 is similar to Figure 5A and 5B A fifth embodiment of the gas processing device 100 is shown, and the same or similar elements are generally indicated herein with the same or similar reference numerals and may not be re-introduced hereinafter.

[0139] exist Figure 6 In the illustrated embodiment, a partition 55A may be provided between adjacent openings of the opening array 55. The partition 55A may be provided with a Figure 4 The described partition 55A is the same or similar and will not be described further.

[0140] Example 7

[0141] Fig. 7A 1 shows a schematic perspective view of a gas processing device 100 according to a non-limiting seventh embodiment of the present invention; and Figure 7B Shown in Fig. 7A Schematic diagram of the gas treatment device 100 observed at the schematic cut plane DD.

[0142] The seventh embodiment of the gas processing device 100 is similar to the Figure 5A and 5B A fifth embodiment of the gas processing device 100 is shown, and the same or similar elements are generally indicated herein with the same or similar reference numerals and may not be re-introduced hereinafter.

[0143] exist Fig. 7A and 7B In the illustrated embodiment, the second side wall 54 of the annular groove is connected to the working gas inlet pipe and the working gas outlet pipe (not shown), so that the inner space of the annular bell mouth forms a working gas input distribution chamber 20 and a working gas output collection chamber 30 respectively.

[0144] In this embodiment, the housing 10 can be mainly used to support the working unit 40, and the internal space of the housing 10 does not directly form the working gas input distribution chamber 20 or the working gas output collection chamber 30. Instead, the working gas directly enters the working gas input distribution chamber 20 via the working gas inlet 11, and the working gas entering the working gas output collection chamber 30 through the working unit 40 can be directly discharged to the outside of the gas processing device 100 via the working gas outlet 12.

Figure 5A and 5B The illustrated embodiment is similarly provided with two chamber dividers 10A which sandwich an array of a plurality of working units 40 therebetween.

As shown in the figure, the size of the position where the inlet 41A and the outlet 42A are connected to the annular bell mouth can match the substantially rectangular opening in the opening array 55. In this way, the effective area available for the arrangement of the inlet 41A and the outlet 42A can be expanded. In this embodiment, the cross section of the annular groove can be formed into an approximately V-shape.

[0151] In addition, as shown in the figure, the shape of the branch connection joint 66 can also match the substantially rectangular openings in the opening array 55 to more efficiently supply the high-temperature gas to the working unit 40.

[0152] according to Fig. 8A and 8B In the embodiment shown in FIG. 4 , the inlet 41A and the outlet 42A can be set to a trapezoid or a nearly trapezoid / roughly trapezoidal shape, so that the effective area of ​​the outer side wall of the annular groove can be maximized. As used herein, the term "trapezoid" refers to the case where the second side wall 54 (i.e., the outer wall) of the annular groove is set to a prism side, and the term "approximately trapezoidal" refers to the case where the second side wall 54 of the annular groove is set to a truncated cone surface, and at this time, the inlet 41A and the outlet 42A of the working unit 40 will form a curved surface shape surrounded by two straight lines and two arcs.

[0153] In this embodiment, the connecting pipes of the working unit (such as the inlet pipe 41 and the outlet pipe 42) form a secondary bell mouth with a gradually expanding cross-section from the trapezoidal or approximately trapezoidal cross-section at the connection with the annular groove to the circular tube or square tube transition section, thereby further reducing wind resistance.

[0154] As Fig. 8A and 8B An alternative embodiment of the eighth embodiment shown in FIG. 8 (not shown in the drawings) may also be similarly provided with the opening array 55 on the first side wall 53, and in this alternative embodiment, the inlet 41A and the outlet 42A may also similarly have a matching shape that transitions to a trapezoidal or substantially trapezoidal shape.

[0163] In addition, Fig.10 In the illustrated embodiment, the contour of the guide port device 50 has a notch 56 in the circumferential direction C, so that the gas processing device 100 can simultaneously perform the working gas processing process and the regeneration process. Fig.10 The gas treatment device 100 shown in FIG. 1 allows the guide port device 50 to rotate synchronously with the rotating regeneration device 60. In this way, the rotating regeneration device can occupy part of the side wall space of the bell mouth without affecting the ideal structure of the entire annular bell mouth to reduce wind resistance.

[0164] In an alternative embodiment not shown, the profile of the guide port device 50 may have a plurality of notches 56 in the circumferential direction C, and these notches 56 may be spaced apart in the circumferential direction C. In this context, such an annular groove having one or more notches 56 may also be referred to as an annular bellmouth.

[0166] As used herein, unless otherwise indicated, the term "substantially" is interpreted to mean plus or minus ten percent of the value or range of values, or to mean that there is a plus or minus ten percent deviation in outline of the shape and / or position.

[0167] The terms "radial direction", "circumferential direction", "left side" or "right side" used herein to indicate the direction or orientation, and the terms "first" or "second" used to indicate the order, etc., are only for the purpose of enabling those skilled in the art to better understand the concept of the present invention shown in the form of a preferred embodiment, and are not used to limit the present invention.
