Description of the Invention: Technical Field of the Invention The present invention relates to air pollution control, and in particular to a device for redirecting a liquid flow in a gas chamber, and thereby improving air pollution control Especially in the selective catalyst reduction. [Prior Art] Prior art systems were unable to achieve full efficiency due to unstable flow in pipeline operations t (especially at corners). SUMMARY OF THE INVENTION An apparatus for reorienting a flow of liquid in a roll is installed by using a planar blade array J to make a relative angle of the liquid flow relative to the inlet (upstream) The flow is tilted and the flow is redirected in the desired direction accordingly. Also known as "GSG" or "gradually straightforward, use" devices are widely used and have many advantages in performance, structure and economy in large-scale applications. As a particular and non-limiting example, one or more embodiments of the fluid redirecting devices taught herein are configured for use in a selective catalytic reactor (SCR), such as for cleaning industrial exhaust gases. In at least one embodiment, a device for redirecting a liquid stream in a plenum from a flow direction to a second flow direction includes a lateral array of planar leaves 2, wherein the blades are An angle is inclined to the first flow direction to redirect the edge liquid flow from the first flow direction to the second flow direction. In this sense, "lateral" means that the blade lines are longitudinally transverse to the fluid to be redirected. The direction. The bevel thus presents 137136.doc 200946785 - a sloping, progressive surface for the inlet/upstream flow such that the windward side of each blade in the row redirects a portion of the flow to a desired direction in another implementation In an example, a method for designing a lateral array of a liquid flow from a first flow direction to a second flow direction of a parachute blade, which includes a lateral blade The length is a function of the internal cross-sectional area at the position of the lateral array to be mounted in the plenum, and at least one of the blade height, the blade pitch and the blade angle is adjusted to ❹ 2 the liquid flow reaches one The desired fluid quality. The method can include adjusting the blade angle by a planned mounting angle of one of the lateral arrays within the adjustment. - or a plurality of such embodiments, adjusting a blade height, blade pitch, and blade angle as desired At least one of them is such that the liquid flow reaches the desired temperature. In the money-to-array-simulation model, the liquid is simulated, the control- or several quality requirements are evaluated, the fluid quality is modeled, and the entire modeled blade is Height, modeled blade spacing, and modeled blade angles - or several until the modeled fluid quality meets one or more of the fluid quality requirements. Such a process may be partially automated or fully automated, such as setting according to design requirements - simulating the model and specifying a preferred design change (9) such as blade height versus pitch adjustment range, and setting the simulation to "see the array." design. Such design requirements may include structure 2 lang including dimensions, stiffness, and the like. Array resetting of the bucket, structural fasteners/buildings zero. Of course, those skilled in the art will appreciate the following detailed description and reference to the drawings. Other features and advantages will be recognized. ^, 137136.doc 200946785 [Embodiment] ® m------ (4)-column 10' (4) is a short grid, or simply "array 1". From this illustration, it can be seen that the array 1 includes a plurality of spaced planar blades 12. The array 1 is configured to be fixedly mounted in the - plenum u to redirect a liquid stream from the first to the flow direction. In particular, it will be appreciated that the novel configuration for redirecting liquid flow provides a high degree of downstream flow field quality in the second flow direction without the need for additional bridge fins downstream of the array 10. This diagram depicts a side view of the array 1G, and it should be understood that the observer sees the end view of the blades 12 $ "@ i目® β », and the blades 12 are perpendicular to the first - Flow direction and longitudinal positioning. Moreover, as shown in the illustrated embodiment, the exemplary installation of the array is located at a corner position or joint of the plenum 14 , i.e., a first plenum section 16 is positioned in the first flow direction and - second The plenum section (10) is positioned at the second direction of flow. Thus, in this example, the array J 10 is configured to redirect the liquid flow at the corner joint between the first and second plenum sections 16 and 18. As can be seen, an exemplary bevel for mounting the array 10 relative to the first flow direction is the "angular" of the corner joint between the plenum sections 16 and 18. It can be seen that the upstream blade edges of the blades 12 define a plane - and in at least some design applications, preferably along the diagonal from the inner plenum 22 to the outer plenum 24 Line 2〇 aligns to this plane. Of course, it should be understood that other alignments may be employed, and the array 10 may be raised or lowered relative to the centerline of the corner to serve as a Γ137137.doc 200946785 number in order to achieve the desired flow field quality, Installation convenience, etc. Moreover, the angle of the array ίο relative to the first flow direction can be increased or decreased as the same performance adjustment parameter' and the bevel angle thus does not need to follow the medial to outer edge. In addition, it should be appreciated that the array 10 can be configured for use in addition to 90 degrees, such as at corners less than 90 degrees, and can be varied as required for flow field quality and mechanical considerations. Installation angle and corner positioning. Referring to Figure 2, we can see an enlarged side view of one of a given embodiment φ @blade 12 including one of the arrays. In particular, the lateral plane of the parent blade 2 can be seen as a reference to the surface of the first flow direction and a relative windward surface. For further reference, each blade 12 is considered to have an upstream (&) edge 34 associated with the inlet/upstream first flow direction and a downstream (lateral) edge 36 associated with the outlet/downstream second flow direction. . These upstream and downstream blade edges are 36/cannot be machined or form an aerodynamic profile. In fact, unprocessed right-angled edges, such as those associated with sheet steel, generally provide the performance acceptable. However, installations with higher flow rates, thicker blades, etc. can benefit from the shaped blade edges. Array Configuration In general, the array 1G - or multiple embodiments are based on one of the blade door degrees hj measured from the m-blade edge 34 to the downstream blade edge %, which is between about 6 inches and about 18 inches. Within the scope of the ,, and in the: car: ": the spacing between the blades 12%", which is in the range of about 3 inches to about 士. Moreover, the bevel angle (i.e., the array 1 〇 relative to the first machine direction, the female skirt angle) can be selected to place the blades 12 in the 6-well array 10 with a blade angle ^, 0 being at about negative 25. It is approximately 25th. Within the scope. 137136.doc 200946785 Of course, regardless of whether the parameters are set within the above range, it should be understood that one or more such parameters can be adjusted to "adjust" the array i as given. . This adjustment can be fixed by one or several and one or more other parameters can be changed in a repeated manner to achieve a design that produces an acceptable flow field quality while also meeting all practical cost and mechanical considerations. In at least one embodiment, a preferred blade height "h" is 12 inches or about 12 inches, and a preferred blade pitch "c" is 6 inches or about 6 inches, and a preferred blade Angle 0 is 19 degrees or about 19 degrees. (We can see in Figure 2 that the measured blade angle is between the line extending from the upstream blade edge 34 to the downstream blade edge 36 and the line parallel to the second flow direction). Thus, if the second flow direction is vertical, the preferred blade angle is 19 degrees or about 19 degrees from the vertical. More broadly, the bevel of the array is selected to place each of the vanes 12 in the array 1 at an angle 0 to +25 degrees (inclusive) relative to the second flow direction, wherein As explained, the blade angle 测 is measured relative to the second flow direction using a line connecting the upstream and downstream blade edges 34 and 36. Further to the array design considerations, in one embodiment, the blade height as measured from the upstream blade edge 34 to the downstream blade edge 36 is configured to be about the blade pitch measured between adjacent blades 12 of the array 10. Twice. Expressed in mathematics. In another embodiment, the ratio is set to 2.5 times, i.e., /; = 2.5c. For at least some installations, the ratio of & is preferred, but it should be understood that the ratio of height to pitch is a candidate adjustment parameter and can be processed as part of the array design process. For example, weight and / or 137136.doc 200946785 cost limits may require a reduced number of blades, savouring that the blade spacing needs to be increased for a given array size. In these situations, for example, all array mounting angles and/or the blade height can be varied to compensate for the reduced number of blades. Referring to Figure 3, we can see a simplified perspective view of the blades 12 in a given array 1〇, which emphasizes the lateral positioning of the blades 12 in the longitudinal direction, and further illustrates the flow from the first to the The second flow is deflected toward the windward surface 30 of the liquid flowing. Although the leeward surface 32 is not visible in Figure 3, one or more embodiments are contemplated herein to include a structural reinforcement that is integrated or mounted to the leeward faces 32 of the blade 12. (The structural reinforcement is shown below for large scale SCR applications). Due to the right, other mechanical and institutional considerations, we should note that this name is given in this article is widely explained. For example, the definition of (4) herein includes, but is not limited to, in the structure—the filling space (eg, rolling stock, air, etc.), and especially the conduit carrying the flowing liquid or Φ he=B, unless otherwise stated, The term does not need to mean a continuous 'for example, a first closed structure (eg, a conduit) can lead to a second closed structure (eg, a space above a scr stack), and the entire first and second structures Or partially visible as the plenum, and the array is mounted therein. In addition: it should be understood that the mounting characteristics of the (4) 1G can be modified as required by the characteristics of the rolled to 14 installed. For example, Figure * depicts a plan view of an array 1G which not only illustrates the lateral positioning of the blades 12, but also shows a perimeter frame 40 that serves as a carrier for the blades 12 and can be used by 137136.doc -11 · 200946785 The array is enclosed in the plenum 14. Thus, in one or more embodiments, the array 1G includes at least a portion of the perimeter frame 4g for: structurally securing the array (4) in the plenum 14. It should also be understood that the array 10 can include two or more sub-arrays. For example, for a large gas chamber cross-sectional area, several smaller arrays 1G can be used to form - a larger array across the desired interior space. This process can provide, for example, better structural integrity and limit individual blade lengths to larger actual values. Moreover, it should be understood that in one or more embodiments, the blades U are evenly spaced within the array 10. However, in one or more embodiments, the blades 12 are unevenly spaced in the array. In other embodiments, a portion of the vanes 12 may be evenly spaced, while other portions may be unevenly spaced. These changes can be taken to take into account structural installations to accommodate obstacles and the like. Of course, all design parameters can be set and adjusted as needed for a given installation. In fact, one of the teachings herein includes a design method whereby computer simulations (and/or experimental scale simulations) and parameter adjustments can produce an array 10 that is configured to give particular installation requirements. Such simulations may be based on computational fluid dynamics (CFD) simulations and experimental scale simulations, and may be implemented in a computer system (eg, a PC) or a portion thereof having a computer readable medium embodying program instructions, in one The array adjustment method is implemented in a fluid simulation environment. Figure 5 illustrates an embodiment of the method 'where the method is "started" from the wheeling design requirement (block 100). This special requirement may be the quality of the flow field expected in the second direction, which may be expressed in terms of laminar flow quality, striking value, and the like. This 137136.doc •12- 200946785 requirements will generally include basic chamber size, fluid volume, velocity, and so on. With appropriate basic design requirements, a method of designing the array 10 includes defining a transverse blade length "[" as a function of an internal cross-sectional area at the location of the array in the plenum 14 to be mounted (block 1 〇 2). The method continues to adjust at least one of the blade height, the blade pitch, and the blade angle as desired to achieve a desired flow field quality of the liquid helium (block 1〇4). This method can be repeated and can be used or controlled by script or other program

Again, this method can be implemented by computer simulation in a fluid simulation environment or in an experimental scale simulation. Figure 6 illustrates one embodiment of repeating array adjustment. This method can represent the details of block 104 in FIG. This array design allows the (iv) or nominal array parameters (such as preset blade height, spacing, and angle) to be initialized (block 11). The method proceeds to a full-scale based on known replacement values (such as - specified blade spacing). Or multiple parameters (square ιΐ2). The method proceeds to execute/evaluate the corresponding simulation model (block i 14). The evaluation includes, for example, comparing the simulated flow field quality to design requirements. If the design criteria are met (in some acceptable ranges of oysters) (block 1 , the method "end., fruit" does not meet the design criteria, and does not exceed an iteration limit or other method limits. (block 118) 'The method proceeds to adjust one or more array parameter pseudo-models (block m). To reverse the second (4) the re-adjustment mode Q repeated adjustments continue as needed, or 137136. Doc 200946785 Until an iteration limit is exceeded. In one or more embodiments, adjusting the array 10 includes adjusting the blade angle by adjusting the mounting angle of one of the arrays 10 within the plenum 14. Alternatively or additionally, at least one of adjusting the blade height, the blade pitch, and the blade angle as needed to achieve a desired flow field quality of the liquid flow. Again, the adjustment may include: at the array 10 Simulating a liquid flow in a simulation model; evaluating a simulated flow field quality against one or more quality requirements; and adjusting one of the simulated blade height, the simulated blade spacing, and the simulated blade angle Or more, until the simulated flow field quality meets one or more flow field quality requirements. Similarly, as described above, at least one of the blade height, the blade pitch, and the blade angle is adjusted as needed to achieve liquid flow. One of the desired flow field qualities may include initializing a lateral array design using a predetermined blade height, a predetermined blade pitch, and a predetermined blade angle and then adjusting one or more of the preset values The preset values may be based on the ratio of the blade height to the blade pitch of about 2: 1 to set the preset blade height and the preset blade pitch. In addition, the adjustment range of one or more adjustment variables may be limited to the previously mentioned Blade height, spacing and angle. With this design flexibility in mind, Figures 7, 8 and 9 illustrate an application example in which the array 10 is configured for use in various SCR applications. In particular, Figure 7 highlights this The leeward side structural reinforcement on the blade 12, and illustrating the mechanical wear feature. The plenum 14 in these illustrations includes an upstream component of a selective catalyst reactor (SCR) 50, and the array is 1 〇 The configuration is to redirect the airflow to the SCR 50. 137136.doc -14· 200946785 However, the array is not limited to the illustrated examples.
