Combined supersonic gas condensation separation device and method

Abstract

This invention discloses a combined supersonic gas condensation and separation device and method, relating to the technical field of condensation separation devices. It includes a main housing, an inlet connecting flange at the inlet end of the main housing, an inlet pipe, an inlet guide plate and a core inlet mounting plate, an outlet connecting flange at the outlet end of the main housing, an outlet manifold cavity, a partition plate, and an outlet connecting seat. Through the cooperation of the stripping channel and segmented stripping ports, the main airflow after condensate stripping can continue to pass through the central region, while the condensate moving along the inner wall of the expanding condensation section can enter the manifold cavity from the segmented stripping ports distributed circumferentially around the stripping channel. Thus, the main airflow path and the condensate stripping path are structurally distinct. Compared to the liquid capture method where the condensate and main airflow pass through the same annular opening, this reduces the likelihood of the condensate being carried away again by the central main airflow at the stripping location, improving the stability of condensate stripping.

Description

Technical Field

[0001] This invention relates to the field of condensation separation device technology, specifically a combined supersonic gas condensation separation device and method. Background Technology

[0002] Supersonic gas condenser separators are typically used to cool and separate liquids from gases containing condensable components. The general process is as follows: the gas to be treated passes through a swirling, contraction, acceleration, and throat section before entering the expansion and condensation section. During the expansion process, the gas cools down, causing moisture, heavy hydrocarbons, or other condensable components to separate out. The condensate is then separated from the main gas flow by a liquid trapping structure. For scenarios with large processing volumes, multiple separation cores are often arranged side by side in the same housing to improve the overall processing capacity.

[0003] In practical use, the combined supersonic condensation separation equipment mainly has the following problems: On the one hand, when multiple separation cores are running in parallel, if there is no effective flow guidance at the inlet end, the gas is prone to concentrate and impact some separation core inlets, resulting in uneven flow patterns and processing loads at the inlets of each separation core, which affects the subsequent expansion condensation effect; on the other hand, the condensate precipitated by the gas in the expansion condensation section usually migrates downstream along the wall surface. If there is no directional flow guidance and segmented stripping structure for the liquid film on the wall surface, the condensate is easily sheared and broken or re-entrained by the high-speed main airflow, resulting in the gas after separation still carrying liquid droplets.

[0004] Furthermore, existing liquid-collecting structures often use annular slits or simple baffles to collect condensate, making it difficult to distinguish the condensate stripping path from the main airflow path. This can easily lead to unstable liquid stripping and discontinuous drainage when the airflow fluctuates. When the outlets of multiple separator cores converge, the lack of separation and guidance can also cause mutual disturbance of the outlet airflow, affecting the flow stability on the outlet side of the separator core.

[0005] To address this issue, we propose a combined supersonic gas condensation and separation device and method. Summary of the Invention

[0006] In view of this, and in view of the shortcomings of the prior art, the present invention provides a combined supersonic gas condensation and separation device and method to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a combined supersonic gas condensation and separation device, comprising a main shell, an inlet end connecting flange disposed at the inlet end of the main shell, an inlet pipe, an inlet guide plate and a core inlet mounting plate, an outlet end connecting flange disposed at the outlet end of the main shell, an outlet end manifold, a partition plate, an outlet end connecting seat, a core outlet mounting plate and multiple outlet side partitions formed through the outlet mounting plate, and at least two supersonic condensation and separation cores installed in parallel between the core inlet mounting plate and the core outlet mounting plate; Each supersonic condenser separation core includes, in sequence along the gas flow direction, a swirling inlet section, a contraction acceleration section, a throat section, an expansion condensation section, and a liquid capture section. The swirling inlet section is equipped with a swirling guide, and the inner wall of the expansion condensation section is equipped with liquid film guide ribs. The liquid-catching section includes a liquid-catching sleeve, a liquid-guiding flange, a liquid-cutting flange, a confluence outlet cavity, a segmented peeling port, a peeling channel, and a drain slit. The segmented peeling port is set corresponding to the downstream end of the liquid film guide rib. The peeling channel is set in the central area of ​​multiple segmented peeling ports, and the multiple segmented peeling ports are distributed circumferentially around the peeling channel. The segmented stripping port is connected to the manifold outlet cavity. The drain slit is located on the side of the manifold outlet cavity facing the lower part of the main housing. The lower part of the main housing is provided with a liquid guiding channel for receiving the condensate drained from the drain slit. The liquid guiding channel is connected to the liquid collecting pipe through a liquid guiding pipe.

[0008] Preferably, the intake pipe is connected to the intake end flange, an intake-side transition cavity is formed in the intake end of the main housing, an intake guide plate is disposed in the intake-side transition cavity, the core inlet mounting plate is located downstream of the intake guide plate, and the inlet ends of multiple supersonic condensation separation cores are respectively installed on the core inlet mounting plate.

[0009] Preferably, the outlet end connecting flange is disposed at the outlet end of the main housing and is used to connect to the external outlet pipe. The outlet end connecting seat is connected to the main housing. The outlet end manifold is formed in the outlet end connecting seat. The partition plate is disposed in the outlet end manifold to separate and guide the airflow discharged from multiple supersonic condenser separation cores.

[0010] Preferably, the swirl guide is disposed within the swirl inlet section, and the swirl guide includes multiple guide vanes arranged at intervals along the circumference, used to cause the gas to be treated entering the supersonic condensation separation core to form a swirling flow.

[0011] Preferably, the throat segment includes a pre-larynx contraction port and a post-larynx expansion port. The pre-larynx contraction port is connected to the contraction acceleration section, and the post-larynx expansion port is connected to the expansion condensation section, so that the gas is accelerated by the contraction acceleration section and then enters the expansion condensation section.

[0012] Preferably, multiple liquid film guide ribs are arranged circumferentially along the expansion condensation section and extend axially along the expansion condensation section to the upstream side of the liquid capture section, and multiple segmented stripping ports are respectively provided corresponding to the downstream ends of multiple liquid film guide ribs.

[0013] Preferably, the liquid-cutting flange is located at the downstream end of the expansion condensation section, the liquid-guiding fold is located on the inner side of the liquid-catching sleeve, and the segmented peeling port is formed at the position where the liquid-cutting flange and the liquid-guiding fold cooperate, so that the condensate moving along the inner wall of the expansion condensation section can enter the manifold outlet cavity through the segmented peeling port.

[0014] Preferably, the stripping channel is located in the central area of ​​multiple segmented stripping ports, which are arranged circumferentially along the stripping channel. The stripping channel is used to allow the main airflow after condensate stripping to continue passing through, and the segmented stripping ports are used to guide the condensate collected along the inner wall of the expansion condensation section into the confluence outlet cavity.

[0015] Preferably, the liquid guiding channel is located at the lower part of the main housing, and the liquid guiding pipe is connected between the liquid guiding channel and the liquid collecting pipe, so that the condensate discharged from the drain slit can enter the liquid guiding channel and flow into the liquid collecting pipe through the liquid guiding pipe.

[0016] A combined supersonic gas condensation and separation method includes the following steps: Step 1: The gas to be treated enters the inlet-side transition chamber through the inlet pipe and is distributed to the inlet end of multiple supersonic condensation separation cores under the guidance of the inlet guide plate. Step 2: The gas to be treated entering the supersonic condenser separation core forms a rotating flow state through the swirling guide in the swirling inlet section, and then enters the expansion condensation section after passing through the contraction acceleration section and the throat section in sequence. Step 3: The gas expands and cools down in the expansion and condensation section, causing the condensable components in the gas to be released and form condensate. The condensate migrates to the inner wall of the expansion and condensation section under the action of swirling centrifugal force and wall adhesion. Step 4: The condensate that migrates to the inner wall of the expansion condensation section forms a liquid film flow under the guidance of the liquid film guide ribs, and is guided by the liquid film guide ribs to the corresponding segmented stripping port; Step 5: The liquid film flow reaching the liquid-catching section, under the combined action of the liquid-cutting flange and the liquid-guiding fold, enters the confluence outlet cavity through the segmented stripping port set around the stripping channel. The stripping channel is for the main airflow to continue to pass through after the condensate stripping is completed. Step 6: The condensate entering the manifold outlet cavity is discharged through the drain slit and enters the liquid guiding channel located at the bottom of the main shell, and then enters the liquid collecting pipe through the liquid guiding pipe for discharge; Step 7: After condensation and separation, the gas enters the outlet manifold through the core outlet mounting plate and is discharged through the outlet flange under the guidance of the partition plate.

[0017] Compared with the prior art, the present invention provides a combined supersonic gas condensation and separation device and method, which has the following beneficial effects: By combining the stripping channel with the segmented stripping ports, the main airflow after condensate stripping can continue to pass through the central region, while the condensate moving along the inner wall of the expansion condensation section can enter the confluence outlet cavity from the segmented stripping ports distributed circumferentially around the stripping channel. Thus, the main airflow path and the condensate stripping path are structurally distinct. Compared with the liquid capture method where the condensate and the main airflow pass through the same annular opening, this method can reduce the situation where the condensate is carried away again by the central main airflow at the stripping position, thereby improving the stability of condensate stripping.

[0018] By matching the liquid film guide ribs with the segmented stripping ports, the condensate on the inner wall of the expansion condensation section can be directionally guided by the liquid film guide ribs as it moves downstream and reaches the vicinity of the corresponding segmented stripping ports. In this way, the condensate does not need to diffuse randomly over a large area in the circumferential direction before entering the liquid capture section, but can enter the stripping position along a predetermined path. This reduces the possibility that the liquid film will be sheared and dispersed by the high-speed airflow at the end of the expansion condensation section, which is beneficial to improving the continuity of the condensate entering the liquid capture section.

[0019] The combination of the liquid-cutting flange and the liquid-guiding fold allows the liquid film moving along the wall to form a clear peeling boundary at the liquid-cutting flange when it reaches the liquid-catching section. The liquid-guiding fold then guides the liquid film into the segmented peeling port. The liquid-cutting flange mainly cuts the liquid film away from the wall boundary area, while the liquid-guiding fold turns and guides the cut liquid film. The combination of the two allows the condensate to enter the segmented peeling port more stably, reducing the possibility of the condensate staying at the entrance of the liquid-catching section or deviating from the peeling path.

[0020] By sequentially coordinating segmented stripping ports, a confluence outlet cavity, a drain slit, a guide channel, a guide pipe, and a collection pipe, a condensate path is formed that continuously drains condensate from the liquid-catching section to the lower drain structure. The confluence outlet cavity is used to merge and transition condensate from multiple segmented stripping ports and guide the condensate to the drain slit. The drain slit is positioned facing the lower guide channel, allowing the condensate to continue entering the guide channel, guide pipe, and collection pipe for discharge. This structure helps reduce condensate retention near the liquid-catching section and lowers the possibility of local liquid re-entering the main airflow after being disturbed by airflow.

[0021] By cooperating with the air intake guide plate and the core inlet mounting plate, the gas to be treated enters the main housing, is first guided through the air intake side transition chamber and the air intake guide plate, and then enters multiple supersonic condensation separation cores. The core inlet mounting plate positions the inlet ends of multiple separation cores, and the air intake guide plate reduces the direct and concentrated impact of the air intake on local inlets, making the air intake state of multiple separation cores more stable. This helps to ensure that the condensation separation process of each separation core in the combined equipment is relatively consistent.

[0022] Through the continuous coordination of the swirling inlet section, swirling guide, contraction acceleration section, throat section, and expansion condensation section, the gas to be treated first forms a swirling flow state, and then condenses after acceleration and expansion cooling. The swirling flow state makes it easier for the condensed liquid to migrate to the inner wall of the expansion condensation section. The liquid film guide ribs on the inner wall of the expansion condensation section further guide the condensed liquid on the wall surface, thereby providing a more stable liquid film source for subsequent segmented stripping.

[0023] By cooperating with the core outlet mounting plate, the outlet manifold, and the separator, the gas discharged from multiple supersonic condenser separators is collected and guided at the outlet. The core outlet mounting plate positions the outlet ends of multiple separators, the outlet manifold provides space for gas collection, and the separator separates and guides the airflow discharged from different separators, reducing direct mutual impact of airflow on the outlet side and helping to maintain stable flow at the outlet.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figures 1 to 3 As shown, the combined supersonic gas condensation separation device in this embodiment includes a main housing 11, an inlet connecting flange 12, an inlet pipe 13, an inlet guide plate 14, a core inlet mounting plate 151, an outlet connecting flange 21, an outlet manifold 22, a partition plate 23, an outlet connecting seat 24, a core outlet mounting plate 31, multiple supersonic condensation separation cores, and a liquid guiding and draining structure. The multiple supersonic condensation separation cores are installed side by side between the core inlet mounting plate 151 and the core outlet mounting plate 31, so that the gas to be treated can be distributed to multiple separation paths within the same main housing 11 to complete supersonic condensation separation.

[0029] In this embodiment, the main housing 11 serves as the mounting base for multiple supersonic condensation separation cores. Its internal space is used to accommodate the inlet-side transition cavity 152, multiple supersonic condensation separation cores, the outlet-end manifold cavity 22, and the liquid guiding and draining structure, thereby enabling the gas processing path and the condensate discharge path to be concentrated in the same equipment housing to form a continuous arrangement.

[0030] like Figure 1 , Figure 2 and Figure 4As shown, the inlet flange 12 is located at the inlet end of the main housing 11, the inlet pipe 13 is connected to the inlet flange 12, the inlet-side transition cavity 152 is formed inside the inlet end of the main housing 11, the inlet guide plate 14 is located in the inlet-side transition cavity 152, and the core inlet mounting plate 151 is located downstream of the inlet guide plate 14. When the equipment is running, the gas to be treated enters the inlet-side transition cavity 152 through the inlet pipe 13 and is first guided by the inlet guide plate 14, and then enters the inlet end of multiple supersonic condensation separation cores through the core inlet mounting plate 151, thereby reducing the situation where the gas directly and centrally impacts the inlet of the local separation core.

[0031] The core inlet mounting plate 151 is used to support and position the inlet ends of multiple supersonic condensation separation cores, so that the multiple supersonic condensation separation cores are arranged in a relatively stable parallel state within the main housing 11. After the air intake guide plate 14 cooperates with the core inlet mounting plate 151, the gas entering the air intake side transition chamber 152 can form a relatively stable distribution state before entering each separation core, which helps to reduce the situation where the air intake state difference between different separation cores is too large.

[0032] like Figure 3 , Figure 8 and Figure 10 As shown, each supersonic condenser separation core includes, in sequence along the gas flow direction, a swirling inlet section 41, a contraction acceleration section 42, a throat section 43, an expansion condensation section 44, and a liquid trapping section 45. After the gas to be treated enters any supersonic condenser separation core, it passes through the swirling inlet section 41, the contraction acceleration section 42, the throat section 43, and the expansion condensation section 44 in sequence. In the expansion condensation section 44, it expands and cools down, causing the condensable components in the gas to separate and form condensate.

[0033] A swirling guide 411 is provided in the swirling inlet section 41. The swirling guide 411 can adopt a guide vane structure arranged in the circumferential direction. When the gas to be treated passes through the swirling guide 411, it is guided by the swirling direction and forms a rotating flow state. The rotating flow state causes the subsequently precipitated condensate to have a tendency to migrate towards the inner wall of the expansion condensation section 44, thereby providing conditions for the formation of the liquid film on the wall and subsequent peeling.

[0034] The contraction acceleration section 42 is located downstream of the swirl inlet section 41, and the throat section 43 is located between the contraction acceleration section 42 and the expansion condensation section 44. The throat section 43 includes a pre-throat contraction port 431 and a post-throat expansion port 432. The pre-throat contraction port 431 is connected to the contraction acceleration section 42, and the post-throat expansion port 432 is connected to the expansion condensation section 44. After passing through the contraction acceleration section 42 and the throat section 43, the gas enters the expansion condensation section 44, so that the gas completes the cooling and liquid precipitation process in the expansion condensation section 44.

[0035] like Figure 7 , Figure 8 and Figure 10 As shown, the inner wall of the expansion condensation section 44 is provided with liquid film guide ribs 441. Multiple liquid film guide ribs 441 are arranged at intervals along the circumference of the expansion condensation section 44 and extend along the axial direction of the expansion condensation section 44 to the upstream side of the liquid capture section 45. When the equipment is running, the condensate migrates to the inner wall of the expansion condensation section 44 under the action of swirling centrifugal force and wall adhesion. It can then be restricted and guided by the liquid film guide ribs 441 and move downstream along the gas flow direction.

[0036] The liquid film guide ribs 441 prevent the wall condensate from relying entirely on the random flow of the inner wall of the expansion condensation section 44 to enter the liquid capture section 45. Instead, it can form a more stable liquid film flow along the liquid film guide ribs 441 and move towards the corresponding segmented stripping port 455. This reduces the possibility of the liquid film being sheared and dispersed by the high-speed airflow at the end of the expansion condensation section 44.

[0037] like Figure 7 and Figure 9 As shown, the liquid-catching section 45 is located downstream of the expansion condensation section 44. The liquid-catching section 45 includes a liquid-catching sleeve 451, a liquid-guiding flange 452, a liquid-cutting flange 453, a flow-out outlet 454, a segmented peeling port 455, a peeling channel 456, and a drain slit 457. The liquid-catching sleeve 451 is located in the outer region downstream of the expansion condensation section 44. The liquid-guiding flange 452 is located on the inner side of the liquid-catching sleeve 451. The liquid-cutting flange 453 is located at the downstream end of the expansion condensation section 44. The segmented peeling port 455 is formed at the position where the liquid-cutting flange 453 and the liquid-guiding flange 452 cooperate.

[0038] The stripping channel 456 is located in the central area of ​​multiple segmented stripping ports 455. The multiple segmented stripping ports 455 are distributed circumferentially around the stripping channel 456. The stripping channel 456 is used to allow the main airflow to continue to pass through after the condensate stripping is completed. The segmented stripping ports 455 are used to introduce the condensate moving along the inner wall of the expansion condensation section 44 into the confluence outlet cavity 454, thereby making the main airflow path and the condensate stripping path structurally separate.

[0039] It should be noted that the stripping channel 456 is not a drainage channel after the condensate enters the segmented stripping port 455, but a main airflow channel located in the central area of ​​multiple segmented stripping ports 455. The condensate enters the confluence outlet cavity 454 through the segmented stripping port 455, and the main airflow continues to flow along the stripping channel 456 to the outlet end, thereby avoiding the condensate from being introduced into the central main airflow channel.

[0040] The liquid cutting flange 453 and the liquid guiding fold 452 cooperate to form a liquid film peeling position. When the equipment is running, after the liquid film from the wall guided by the liquid film guide rib 441 reaches the liquid capturing section 45, the liquid cutting flange 453 forms a cutting boundary for the liquid film, and the liquid guiding fold 452 guides the cut liquid film, so that the condensate can enter the confluence outlet cavity 454 through the corresponding segmented peeling port 455, thereby reducing the situation where the condensate lingers near the inlet of the liquid capturing section 45 or deviates from the peeling path.

[0041] The manifold outlet cavity 454 is connected to the segmented stripping port 455. The manifold outlet cavity 454 is used to merge and continuously discharge the condensate introduced by multiple segmented stripping ports 455. The manifold outlet cavity 454 is not used as a liquid storage space. When the equipment is running, the condensate entering the manifold outlet cavity 454 continues to flow toward the drain slit 457, so that the condensate can leave the area near the liquid collection section 45 as soon as possible after the stripping is completed.

[0042] The drain slit 457 is located on the side of the manifold outlet cavity 454 facing the lower part of the main housing 11. The drain slit 457 is used to drain the condensate in the manifold outlet cavity 454 to the lower part of the main housing 11. When the equipment is running, the condensate completes the transition in the manifold outlet cavity 454 and is discharged through the drain slit 457, thereby reducing the possibility of local liquid remaining near the liquid collection section 45 and being disturbed by airflow.

[0043] like Figure 3 As shown, a liquid guiding channel 51 is provided at the lower part of the main housing 11. The liquid discharge slit 457 is set towards the liquid guiding channel 51. The liquid guiding channel 51 is connected to the liquid guiding pipe 52, and the liquid guiding pipe 52 is connected to the liquid collecting pipe 54. When the equipment is running, the condensate discharged through the liquid discharge slit 457 enters the liquid guiding channel 51, then enters the liquid collecting pipe 54 through the liquid guiding pipe 52 and is discharged outward, so that the condensate separated by the liquid capturing section 45 can be continuously discharged along the lower liquid guiding and discharge structure.

[0044] The liquid guiding channel 51, the liquid guiding pipe 52 and the liquid collecting pipe 54 cooperate to form the condensate discharge path at the bottom of the main shell 11. This discharge path cooperates with the liquid capturing section 45 of multiple supersonic condensation separation cores, so that the condensate stripped from different separation cores can enter the lower liquid guiding and discharge structure and be discharged, thereby avoiding the condensate from staying in the area near the main airflow for a long time.

[0045] like Figure 3 , Figure 5 and Figure 6As shown, the outlet structure includes an outlet connecting flange 21, an outlet manifold 22, a partition plate 23, an outlet connecting seat 24, a core outlet mounting plate 31, and an outlet side partition 32. The outlet ends of multiple supersonic condensation separation cores are mounted on the core outlet mounting plate 31. The outlet connecting flange 21 is located at the outlet end of the main housing 11 and is used to connect to the external outlet pipe. When the equipment is running, the gas after condensate stripping enters the outlet manifold 22 through the core outlet mounting plate 31.

[0046] It should be noted that the number of outlet-side cavities 32 is the same as the number of supersonic condensing separator cores. The side of the outlet-end manifold 22 closest to the supersonic condensing separator core is used for the insertion and installation of the supersonic condensing separator core. The gas processed by the supersonic condensing separator core will pass through the outlet-side cavities 32 and finally enter the interior of the outlet-end manifold 22.

[0047] The separator 23 is installed in the outlet end manifold 22 to separate and guide the airflow discharged from multiple supersonic condenser separation cores. When the equipment is running, the gas discharged from different separation cores is gathered in the outlet end manifold 22 and discharged through the outlet end connecting flange 21 under the guidance of the separator 23, thereby reducing the direct mutual impact of the outlet airflow of multiple separation cores during the confluence process.

[0048] In summary, the operation process of this embodiment unfolds sequentially with the equipment structure. After the gas to be treated enters through the inlet pipe 13, it is distributed to multiple supersonic condensation separation cores through the inlet guide plate 14 and the core inlet mounting plate 151. The gas undergoes swirling, acceleration, and expansion condensation sequentially within each separation core. The condensate enters the segmented stripping port 455 surrounding the stripping channel 456 under the guidance of the liquid film guide rib 441, and is discharged through the confluence outlet cavity 454, the drain slit 457, the liquid guide channel 51, the liquid guide pipe 52, and the liquid collection pipe 54. The separated gas is discharged through the outlet confluence cavity 22 and the outlet connecting flange 21.

[0049] Example 2

[0050] A combined supersonic gas condensation and separation method includes the following steps: Step 1: The gas to be treated enters the inlet-side transition chamber 152 through the inlet pipe 13, and is distributed to the inlet end of multiple supersonic condensation separation cores under the guidance of the inlet guide plate 14. Step 2: The gas to be treated entering the supersonic condensation separation core forms a rotating flow state through the swirling guide 411 in the swirling inlet section 41, and then enters the expansion condensation section 44 after passing through the contraction acceleration section 42 and the throat section 43 in sequence. Step 3: The gas expands and cools down in the expansion and condensation section 44, causing the condensable components in the gas to be separated and form condensate. The condensate migrates to the inner wall of the expansion and condensation section 44 under the action of swirling centrifugal force and wall adhesion. Step 4: The condensate that migrates to the inner wall of the expansion condensation section 44 forms a liquid film flow under the guidance of the liquid film guide ribs 441, and is guided by the liquid film guide ribs 441 to the corresponding segmented stripping port 455. Step 5: The liquid film flow reaching the liquid-catching section 45, under the combined action of the liquid-cutting flange 453 and the liquid-guiding fold 452, enters the confluence outlet cavity 454 through the segmented peeling port 455 set around the peeling channel 456. The peeling channel 456 is used for the main airflow after the condensate peeling is completed to continue to pass through. Step 6: The condensate entering the manifold outlet cavity 454 is discharged through the drain slit 457 and enters the liquid guiding channel 51 located at the lower part of the main shell 11, and then enters the liquid collecting pipe 54 through the liquid guiding pipe 52 for discharge. Step 7: After condensation and separation, the gas enters the outlet manifold 22 through the core outlet mounting plate 31, and is discharged through the outlet connecting flange 21 under the separation and guidance of the partition plate 23.
