Description

Technical Field

[0001] This invention relates to the field of carbon disulfide separation technology, and in particular to a liquid collector and a preliminary carbon disulfide separation tower containing the collector. Background Technology

[0002] In chemical separation, distillation, and absorption processes, towers are core equipment. Their internal liquid collectors collect liquid flowing from the upper packing or components, achieving gas-liquid separation and centralized liquid removal, directly impacting the tower's separation efficiency, operational stability, and service life. Currently, the traditional liquid collectors widely used in industrial towers are mostly fixed structures, including annular troughs, baffle types, and tray types. Their core design logic is to achieve liquid collection through fixed guide surfaces or collection spaces. These collectors are simple in structure, have low manufacturing costs, and can meet basic usage requirements under normal operating conditions.

[0003] However, when dealing with special operating conditions such as carbon disulfide separation (sulfur-containing liquids, flammable and volatile media, pressurized operation, and easy scaling) and high-load operation scenarios, the inherent design defects of traditional fixed-structure liquid collectors become increasingly prominent. They are difficult to adapt to the requirements of efficient, stable, and long-cycle operation, and have certain disadvantages and shortcomings. For example, the angle and position of traditional fixed guide plates or baffles are fixed, and the liquid flows down the fixed plate surface and drips directly into the collection tank. On the one hand, the falling droplets are mostly in a fine and dispersed state, which are easily blown off course by the impact of rising gas in the tower, and some droplets cannot fall into the collection tank, resulting in leakage. On the other hand, fine droplets are prone to secondary splashing under airflow disturbance, and may even be carried by the airflow to the upper packing area, which not only reduces the liquid collection rate, but also interferes with the gas-liquid mass transfer process, leading to a decrease in tower separation efficiency. Especially in carbon disulfide separation towers, where the viscosity of sulfur-containing liquids is slightly higher, some droplets are prone to adhering to the wall or flowing down the tower wall. Traditional fixed structures lack targeted interception and guiding designs, making the leakage problem more obvious. Summary of the Invention

[0004] Therefore, it is necessary to provide a liquid collector that avoids droplet splashing and a carbon disulfide preliminary separation tower containing the collector to address the above-mentioned technical problems.

[0005] The present invention provides a liquid collector, comprising a tower body and a packing layer arranged in a linear array from top to bottom inside the tower body, and further comprising: The air inlet is located on one side of the lower part of the tower body; The air outlet is located at the top of the tower body; The collection ring is fixedly installed inside the tower body, located below the topmost packing layer; A collection cylinder is fixedly installed below the collection ring, and a liquid collection tank is provided inside it; The liquid outlet pipe is fixedly inserted through one side of the tower body and is connected to the liquid collection tank; A fixing ring is fixedly installed at the intersection of the collecting ring and the collecting cylinder, and is hollow inside; The slots are arranged in a ring array on the fixed ring, and the number of slots is set to multiple. A guide vane is movably connected to the slot, with one side tilted downwards; A flow guiding component is disposed inside the fixed ring and is used to drive the flow guiding plate to swing.

[0006] In one embodiment, the flow guiding assembly includes a fixing rod that movably passes through the flow guiding plate and is rotatably connected at both ends to the inner walls of the slot on both sides. The end of the flow guiding plate away from the fixing ring is inclined downwards, and the other end is located inside the fixing ring. The bottom of the end is fixedly connected to the inner wall of the fixing ring by a return spring.

[0007] In one embodiment, a movable ring is movably installed inside the fixed ring, and multiple protrusions are fixedly installed in a ring array on the movable ring. A top block is fixedly provided at the bottom of the guide plate on one side of the reset spring, and the protrusions and the top block are movably abutted against each other.

[0008] In one embodiment, there is a certain gap between adjacent guide plates, and the middle part of the collection cylinder is hollow.

[0009] In one embodiment, the guide plate has a through groove at its end and a recess inside the guide plate. A baffle is movably disposed in the recess, and one end of the baffle movably abuts against the inner wall of the through groove.

[0010] In one embodiment, the end of the baffle away from the through groove is located inside the groove, and a movable plate is fixedly connected to the end of the baffle, the movable plate being slidably connected to the groove.

[0011] In one embodiment, the guide plate has a circular groove at the position of the fixed rod, the circular groove is connected to the groove, a limiting ring is fixedly sleeved on the outside of the fixed rod, the limiting ring has an arc groove, and the end of the movable plate away from the baffle is slidably embedded with the limiting ring and the surface of the arc groove.

[0012] In one embodiment, the upper surface of the guide plate is provided with a plurality of through holes, and a sharp tooth block is movably disposed in the through holes.

[0013] In one embodiment, the bottom of the toothed block is located inside the groove and is connected together by a lifting plate. The top of the lifting plate is fixedly connected to the inner wall of the groove by a positioning spring, and the toothed block is movably disposed inside the positioning spring.

[0014] In one embodiment, the lifting plate is made of a lightweight material.

[0015] In one embodiment, the bottom of the lifting plate is provided with a plurality of arc-shaped blocks arranged in a linear array, the movable plate is located below the lifting plate, and the upper surface is provided with a plurality of top rods arranged in a horizontal linear array, the top of the top rods being in movable contact with the bottom of the lifting plate and the arc-shaped blocks.

[0016] In one embodiment, a carbon disulfide preliminary separation tower includes the aforementioned liquid collector.

[0017] The aforementioned liquid collector and carbon disulfide preliminary separation tower containing the collector accelerate the liquid's slide down the plate surface through the reciprocating oscillation of the guide plate, forming a more concentrated liquid flow that is less likely to be deflected by gas. The oscillation can also shake off liquid droplets adhering to the wall, reducing leakage. The reciprocating movement of the baffle allows the liquid to flow down the channel in clusters, making it less likely to be deflected by gas and significantly reducing splashing. The reciprocating extension and retraction of the toothed blocks on the surface of the guide plate can generate local disturbances in the liquid, making it easier for the liquid to slide down the plate surface and less likely to form a "dead zone" on the plate surface.

[0026] The following is combined Figures 1-10 The present invention describes a liquid collector and a carbon disulfide preliminary separation tower containing the collector.

[0027] like Figures 1-6 As shown, in one embodiment, a liquid collector includes a tower body 1 and a packing layer 2 arranged in a linear array from top to bottom inside the tower body 1, and further includes: The air inlet 101 is located on one side of the lower part of the tower body 1; Air outlet 102 is located at the top of tower body 1; The collecting ring 3 is fixedly installed inside the tower body 1, located below the top packing layer 2; The collecting cylinder 4 is fixedly installed below the collecting ring 3, and a liquid collection tank 41 is opened inside it; The liquid outlet pipe 5 is fixedly inserted through one side of the tower body 1 and is connected to the liquid collection tank 41. The fixing ring 6 is fixedly installed at the intersection of the collecting ring 3 and the collecting cylinder 4, and is hollow inside; Slot 61, a ring array is formed on the fixed ring 6, and the number is set to multiple; The guide plate 7 is movably connected to the slot 61, with one side tilted downwards; The flow guiding component 8 is located inside the fixed ring 6 and is used to drive the flow guiding plate 7 to swing.

[0028] Specifically, the gas-liquid mixture (also known as process gas) exiting the reactor includes unreacted sulfur, methane, and generated carbon disulfide and hydrogen sulfide gases. After passing through a sulfur condenser, it enters the interior of tower 1 through inlet 101 at the bottom of tower 1. Most of the liquid sulfur sinks and is discharged from the bottom of tower 1, while the mixed process gas, carrying a small amount of sulfur, rises upwards along the interior of tower 1, passing through multiple layers of packing 2. The packing 2 accelerates the removal of sulfur components from the mixed gas. After passing through the top packing layer 2, the mixed gas is discharged through outlet 102. A spray device is usually installed above the packing layer 2 to spray liquid carbon disulfide into the interior of tower 1. In the packing layer 2, the liquid directly contacts the process gas in countercurrent flow for vaporization and cooling, which can further purify the mixed gas. During this process, some liquid inside the tower body 1 will fall to the bottom of the tower body 1, and some liquid will also slide down the inner wall of the tower body 1. The liquid on the pulley on the inner wall of the tower body 1 can be collected by the collecting ring 3. The liquid on the inner wall of the tower body 1 flows into the surface of the fixed ring 6 through the collecting ring 3, and then flows down along the guide plate 7 into the liquid collection tank 41 opened in the collecting cylinder 4. After a certain amount is collected, it is discharged through the liquid outlet pipe 5. During this process, the guide plate 7 is driven by the guide component 8 to swing up and down relative to the tank opening 61, which can further improve the liquid collection efficiency.

[0029] See Figures 3-7 As shown, in this embodiment, the flow guiding component 8 includes a fixing rod 81, which movably passes through the flow guiding plate 7 and is rotatably connected to the inner walls of both sides of the slot 61. The end of the flow guiding plate 7 away from the fixing ring 6 is tilted downwards, and the other end is located inside the fixing ring 6. The bottom of the end is fixedly connected to the inner wall of the fixing ring 6 by a return spring 82.

[0030] Specifically, when the guide plate 7 is pushed upwards at one end inside the fixed ring 6, the return spring 82 is stretched, and the guide plate 7 swings downwards towards the liquid collection tank 41. Subsequently, when the upward force applied to the guide plate 7 is removed, the return spring 82 will pull the end of the guide plate 7 inside the fixed ring 6 downwards back to its initial position, thus realizing the reciprocating swing of the guide plate 7. In the prior art, the guide plate 7 is usually designed to be fixed, and the liquid drips directly from the end of the guide plate 7, which is easily impacted by rising gas, and some droplets... Being blown off course or even blown back into tower 1 reduces collection efficiency. The oscillating motion causes the liquid to slide down the plate surface more quickly, forming a more concentrated liquid flow that is less likely to be blown off course by the gas. The oscillation can also shake off the liquid droplets hanging on the wall, reducing leakage. Secondly, while collecting the liquid, the mixed gas continues to rise. The oscillation causes the gap between the guide plates 7 to change periodically, producing a "pumping effect" that promotes gas discharge, makes the gas flow more uniform, and improves the gas-liquid mass transfer efficiency in tower 1. The fixed rod 81 provides support for the oscillation of the guide plates 7.

[0031] See Figures 4-7As shown, in this embodiment, a movable ring 83 is movably installed inside the fixed ring 6, and a plurality of protrusions 84 are fixedly installed in a ring array on the movable ring 83. A top block 85 is fixedly provided at the bottom of the guide plate 7 on one side of the reset spring 82, and the protrusions 84 and the top block 85 are movably abutted against each other.

[0032] Specifically, the rotation of the movable ring 83 will cause the protrusion 84 to rotate synchronously. During the rotation, the protrusion 84 will abut against the top block 85, pushing the top block 85 to move upward, causing the guide plate 7 located inside the fixed ring 6 to tilt upward, thereby stretching the return spring 82. When the protrusion 84 moves away from under the top block 85, the return spring 82 will pull the guide plate 7 back to its original state, which can realize the swing of the guide plate 7. The driving method of the movable ring 83 can be magnetic coupling drive. The drive motor is installed on the outside of the tower body 1, and the movable ring 83 is driven to rotate inside the fixed ring 6 through magnetic coupling. The motor is not installed inside the tower body 1, which is safer and eliminates the risk of leakage.

[0033] See Figure 5 As shown, in this embodiment, there is a certain gap between adjacent guide plates 7, and the middle part of the collection cylinder 4 is hollow.

[0034] Specifically, there is a certain gap between the guide plates 7 to facilitate the upward flow of the gas below through the guide plates 7, and finally discharge through the outlet 102.

[0035] See Figures 4-9 As shown, in this embodiment, a through groove 71 is provided at the end of the guide plate 7, and a groove 72 is provided inside the guide plate 7. A baffle 9 is movably disposed in the groove 72, and one end of the baffle 9 is movably abutting against the inner wall of the through groove 71.

[0036] Specifically, during the swinging process, the baffle 9 alternately blocks and opens the channel 71. When the baffle 9 completely blocks the channel 71, the liquid left on the guide plate 7 enters the channel 71 and settles inside. Then the baffle 9 moves into the groove 72, and the channel 71 is opened with a small opening. The liquid flows out in streams from this small opening. The liquid mass is large and it is not easily blown off course by the gas, and splashing is greatly reduced.

[0037] See Figures 4-9 As shown, in this embodiment, the end of the baffle 9 away from the through groove 71 is located inside the groove 72, and the end is fixedly connected to a movable plate 10, which is slidably connected to the groove 72.

[0038] Specifically, when the movable plate 10 moves into the groove 72, it pulls the baffle 9 to move synchronously, opening the channel 71. Similarly, when the movable plate 10 moves outward from the groove 72, the baffle 9 moves outward synchronously, resealing the channel 71. This allows a certain amount of liquid to be stored before it falls in a concentrated manner, preventing splashing.

[0039] See Figure 8 and Figure 9 As shown, in this embodiment, the guide plate 7 is provided with a circular groove 73 at the position of the fixed rod 81. The circular groove 73 is connected to the groove 72. A limiting ring 11 is fixedly sleeved on the outside of the fixed rod 81. An arc groove 111 is provided on the limiting ring 11. The end of the movable plate 10 away from the baffle 9 is slidably embedded in the surface of the limiting ring 11 and the arc groove 111.

[0040] Specifically, when the guide plate 7 rotates relative to the fixed rod 81, the fixed rod 81 and the limiting ring 11 remain stationary, and the movable plate 10 swings along with the guide plate 7. When one end of the movable plate 10 moves from a high position to a low position along the arc groove 111, the movable plate 10 moves towards the inside of the groove 72, causing the through groove 71 to open a small opening, and the liquid flows down in clusters. Similarly, when one end of the movable plate 10 moves from a low position to a high position along the arc groove 111, the movable plate 10 drives the baffle 9 to move and re-seal the through groove 71, and the stored liquid is discharged in a concentrated manner. The circular groove 73 provides a space for the limiting ring 11 to accommodate it.

[0041] See Figure 8 As shown, in this embodiment, the upper surface of the guide plate 7 is provided with a plurality of through holes 74, and a sharp tooth block 12 is movably disposed in the through holes 74.

[0042] Specifically, during the reciprocating swing of the guide plate 7, the toothed block 12 extends and retracts up and down within the through hole 74. The sulfur-containing liquid easily forms a continuous liquid film on the plate surface, resulting in a slow flow rate. When the toothed block 12 moves up and down, it can break the liquid film, forming multiple fine liquid streams and reducing the residence time of the liquid on the plate surface. Secondly, when the toothed block 12 moves, it will generate local disturbances in the liquid, making it easier for the liquid to slide down the plate surface and less likely to form a "dead zone" on the plate surface.

[0043] See Figure 8 and Figure 9 As shown, in this embodiment, the bottom of the toothed block 12 is located inside the groove 72 and is connected together by the lifting plate 13. The top of the lifting plate 13 is fixedly connected to the inner wall of the groove 72 by the positioning spring 14, and the toothed block 12 is movably disposed inside the positioning spring 14.

[0044] Specifically, the up-and-down reciprocating movement of the lifting plate 13 within the groove 72 will cause the toothed block 12 to move up and down synchronously. During this process, the positioning spring 14 will deform, and the up-and-down movement of the toothed block 12 will accelerate the speed at which the liquid slides down the surface of the guide plate 7.

[0045] In this embodiment, the lifting plate 13 is made of a lightweight material.

[0046] Specifically, the lifting plate 13 is made of a lightweight material, which makes it easier for the positioning spring 14 to drive the lifting plate 13 back to its initial state.

[0047] See Figures 8-10 As shown, in this embodiment, the bottom of the lifting plate 13 is provided with a plurality of arc-shaped blocks 15 in a linear array, the movable plate 10 is located below the lifting plate 13, and the upper surface is provided with a plurality of top rods 16 in a horizontal linear array. The top of the top rods 16 is in movable contact with the bottom of the lifting plate 13 and the arc-shaped blocks 15.

[0048] Specifically, during the reciprocating swing of the guide plate 7, the movable plate 10 also moves laterally back and forth within the groove 72. During the movement of the movable plate 10, the push rod 16 moves synchronously. During the movement of the push rod 16, it will abut against the arc block 15, pushing the arc block 15 and the lifting plate 13 to move upward. This process will compress the positioning spring 14. When the push rod 16 moves to one side of the arc block 15, the positioning spring 14 returns to its original state and pushes the lifting plate 13 and the toothed block 12 downward to the initial position. Through the cooperation of the arc block 15 and the push rod 16, the toothed block 12 can be reciprocated and lifted within the through hole 74.

[0049] In this embodiment, a carbon disulfide preliminary separation tower includes the aforementioned liquid collector.

[0050] Specifically, in addition to the liquid collector mentioned above, the carbon disulfide preliminary separation tower may also be equipped with a spray device, a waste liquid collection device, etc.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the 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 modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
