Description

Technical Field

[0001] This invention relates to the field of waste gas purification technology, and in particular to a spray cooling mechanism and a carbon disulfide preliminary separation tower containing the mechanism. Background Technology

[0002] In the industrial production and recycling of carbon disulfide, the preliminary separation tower is one of the core pieces of equipment. Its main function is to pretreat mixed waste gas containing carbon disulfide. Through spray absorption or condensation, the carbon disulfide in the waste gas is transferred to the liquid phase, realizing preliminary gas-liquid separation, laying the foundation for subsequent refining processes, while reducing the pollution of the environment caused by carbon disulfide emissions and reducing resource waste.

[0003] In existing technologies, the spray purification structure of carbon disulfide preliminary separation towers generally adopts the traditional layout of "spray head + packing layer". The working process is as follows: spray heads are installed at the top of the separation tower, and spray low-temperature absorption oil (wash oil) or cooling circulating water into the tower. The absorption oil absorbs carbon disulfide in the waste gas by relying on the principle of similar dissolves like, while the cooling circulating water condenses the carbon disulfide vapor into liquid by cooling. The packing layer is set directly below the spray head, and mostly uses structured packing or random packing. The mixed waste gas containing carbon disulfide rises from the bottom of the tower, passes through the packing layer, and comes into contact with the liquid sprayed from the spray head on the surface of the packing. Through gas-liquid mass transfer, the absorption and condensation of carbon disulfide are achieved. After the preliminary separation is completed, the purified waste gas is discharged from the top of the tower, and the liquid phase containing carbon disulfide is collected from the bottom of the tower and sent to the subsequent process for further treatment.

[0004] However, in practical applications, the aforementioned conventional spray purification devices suffer from numerous shortcomings and disadvantages due to limitations in their structural design. For example, the liquid sprayed from the spray head falls naturally, relying primarily on gravity to contact the exhaust gas. The liquid falls rapidly, has a short residence time, and easily forms a continuous liquid film on the surface of the packing layer. This causes a large amount of liquid to flow along the packing layer wall or liquid film, creating a "wall flow short circuit" phenomenon, preventing sufficient contact with the exhaust gas. Simultaneously, as the exhaust gas passes through the packing layer from bottom to top, the liquid film obstructs the flow, leading to airflow deviation and localized dead zones. This results in limited contact area and insufficient contact time between the gas and liquid phases, incomplete absorption of gaseous carbon disulfide, and ultimately, low exhaust gas purification efficiency, failing to effectively meet the separation requirements for carbon disulfide exhaust gas. Summary of the Invention

[0005] Therefore, it is necessary to provide a spray cooling mechanism that can improve the degree of gas-liquid mixing and a carbon disulfide preliminary separation tower containing the above-mentioned technical problems.

[0013] A fixed frame is fixedly installed at the end of the movable rod away from the rotating cylinder, and a groove is provided on it;

[0014] The spraying component is located inside the rotating cylinder and is used to drive the fixed frame to rotate.

[0015] In one embodiment, the spraying assembly includes a circular groove formed inside the rotating cylinder. The end of the movable rod away from the fixed frame is located inside the circular groove, and a bevel gear is fixedly sleeved at its end. A fixed cylinder is movably sleeved on the outside of the rotating rod. The top of the fixed cylinder is fixedly connected to the bottom of the positioning plate. A ring is fixedly sleeved on the outside of the fixed cylinder, and a transmission gear is provided on the ring. The bevel gear meshes with the transmission gear for transmission.

[0016] In one embodiment, the rotating rod extends through the rotating cylinder at one end away from the positioning plate, and a turbine blade is fixedly connected to the end of the rotating rod, the turbine blade being located below the spray head.

[0017] In one embodiment, a slot is provided on one side of the fixing frame, and a horizontal groove is provided on the side of the fixing frame located in the groove. The horizontal groove, the slot, and the groove are interconnected. A baffle is movably arranged in the horizontal groove, and multiple drainage holes are provided on the baffle.

[0018] In one embodiment, a crossbar is rotatably disposed within the slot, and a curved groove is formed on one side of the crossbar. The crossbar is located below the baffle, and a limit rod is fixedly disposed at the bottom of the baffle. The end of the limit rod away from the baffle slides and fits against the curved groove.

[0019] In one embodiment, a movable plate is movably disposed on the other side of the groove, a positioning rod is fixedly disposed on the top of the movable plate, an arc-shaped groove is opened at the end of the crossbar away from the curved groove, and the end of the positioning rod away from the movable plate slides and fits into the arc-shaped groove.

[0020] In one embodiment, a fixed ring is fixedly disposed above the fixed cylinder, and a protrusion is provided on the fixed ring. A round rod is movably disposed inside the movable rod. The round rod moves laterally relative to the movable rod, and the two rotate coaxially. One end of the round rod slides and fits against the fixed ring and the protrusion. One end of the round rod movably passes through the fixed frame and is located inside the slot, and the other end is fixedly disposed through the movable plate.

[0021] In one embodiment, a connecting plate is fixedly connected to the end of the round rod, and the connecting plate is fixedly connected to the inner wall of the slot by a plurality of positioning springs.

[0022] In one embodiment, the groove has a plurality of vertical slots arranged in a linear array, and a partition is movably disposed in the vertical slot.

[0026] The aforementioned spray cooling mechanism and carbon disulfide preliminary separation tower containing this mechanism, through the spraying component driving the movable rod and fixed frame to rotate once, throws the liquid in the groove out. The rotation and spraying give the liquid centrifugal force and tangential velocity, forming ultrafine droplets, which greatly increases the gas-liquid contact area and improves the mixing degree of carbon disulfide gas and spray liquid in the exhaust gas. The liquid is thrown outward through the leakage hole, which shears, throttles, and tears the liquid, directly breaking large droplets / liquid films into fine droplets. The fine droplets have a large specific surface area, which allows for more thorough contact with the flue gas, resulting in higher cooling, absorption, and desulfurization efficiency. The lifting and lowering movement of the baffle plate generates forced disturbance to the liquid at the bottom of the groove, preventing high-viscosity liquids (such as liquid sulfur) from settling and scaling at the bottom. The disturbance makes the liquid mix more evenly and avoids unstable throwing effect caused by concentration / temperature stratification. Attached Figure Description

[0044] The following is combined Figures 1-9 The present invention describes a spray cooling mechanism and a carbon disulfide preliminary separation tower containing the mechanism.

[0045] like Figures 1-4 As shown, in one embodiment, a spray cooling mechanism includes a tower body 1 and an air inlet 101 opened at the bottom of the tower body 1, and further includes:

[0046] Air outlet 102 is located at the top of tower body 1;

[0047] Water inlet pipe 2 is installed on one side of tower body 1 and connected to the spray head inside tower body 1;

[0048] Positioning plate 3 is fixedly installed inside tower body 1, located below the spray head;

[0049] Rotating rod 4 is rotatably connected at its top to the bottom of positioning plate 3;

[0050] The rotating cylinder 5 is fixedly connected to the end of the rotating rod 4 away from the positioning plate 3;

[0051] The movable rods 6 are rotatably mounted in a ring array on the outside of the rotating cylinder 5, and multiple rods are set in number.

[0052] A fixed frame 7 is fixedly installed on the end of the movable rod 6 away from the rotating cylinder 5, and a groove 71 is provided on it;

[0053] The spraying component 8 is located inside the rotating cylinder 5 and is used to drive the fixed frame 7 to rotate.

[0054] Specifically, waste gas is introduced into the tower body 1 through the air inlet 101 and rises along the interior of the tower body 1. At the same time, liquid carbon disulfide is supplied to the spray head through the water inlet pipe 2. The liquid is sprayed out through the spray head and mixes with the rising waste gas. The unvaporized low-temperature liquid CS2 droplets come into direct contact with the high-temperature flue gas and the gaseous components in the flue gas. Sensible heat exchange is completed through heat conduction and convection, which further reduces the temperature of the flue gas. At the same time, some of the supersaturated gaseous CS2 in the flue gas condenses and liquefies due to the temperature drop, achieving the initial effect of gas-liquid separation. The purified gas is discharged through the air outlet 102 at the top. The liquid sprayed by the spray head falls naturally and mainly relies on gravity to contact the waste gas. The liquid falls quickly and has a short residence time, resulting in a short contact time with the gas and a poor gas purification effect. A fixed frame 7 is set below the spray head, and the liquid is caught by the groove 71 opened in the fixed frame 7. The rotation of the rotating rod 4 will drive the rotating cylinder 5, the movable rod 6 and the fixed frame 7 to revolve synchronously. During this process, the groove 71 faces upward, which makes it easier to catch the liquid. After rotating a certain distance, the throwing component 8 drives the movable rod 6 and the fixed frame 7 to rotate one revolution, throwing the liquid in the groove 71 out. The flipping and throwing gives the liquid centrifugal force and tangential velocity, forming ultrafine droplets, which greatly increases the gas-liquid contact area and improves the degree of gas-liquid mixing. The positioning plate 3 provides support for the rotating rod 4.

[0055] See Figures 2-4As shown, in this embodiment, the spraying component 8 includes a circular groove 81, which is opened inside the rotating cylinder 5. The end of the movable rod 6 away from the fixed frame 7 is located inside the circular groove 81, and a bevel gear 82 is fixedly sleeved at the end. A fixed cylinder 83 is movably sleeved on the outside of the rotating rod 4. The top of the fixed cylinder 83 is fixedly connected to the bottom of the positioning plate 3. A ring 84 is fixedly sleeved on the outside of the fixed cylinder 83. A transmission gear 85 is provided on the ring 84. The bevel gear 82 meshes with the transmission gear 85 for transmission.

[0056] Specifically, the rotation of the rotating rod 4 drives the rotating cylinder 5, the movable rod 6, and the fixed frame 7 to revolve synchronously. During the rotation of the movable rod 6, the bevel gear 82 on one side rotates along the surface of the ring 84, while the fixed cylinder 83 and the ring 84 remain stationary. When the bevel gear 82 is not engaged with the transmission gear 85, the groove 71 faces upward, which can catch the spilled liquid. When the movable rod 6 drives the bevel gear 82 to rotate and engage with the transmission gear 85, it will drive the movable rod 6 and the fixed frame 7 to rotate one revolution, throwing the liquid collected in the groove 71 out, so that the liquid gains centrifugal force and tangential velocity, forming ultrafine droplets, which greatly increases the gas-liquid contact area and can improve the purification efficiency of the exhaust gas. The groove 81 provides a space for the ring 84 to accommodate it.

[0057] See Figure 2 As shown, in this embodiment, the end of the rotating rod 4 away from the positioning plate 3 moves through the rotating cylinder 5, and the end is fixedly connected to a turbine fan blade 9, which is located below the spray head.

[0058] Specifically, the turbine blade 9 is located below the spray head and will first come into contact with the rising exhaust gas. The airflow driven by the rising exhaust gas will cause the turbine blade 9 to rotate, thereby driving the rotating rod 4 to rotate, which in turn drives the fixed frame 7 to rotate, ultimately achieving liquid spraying. There is no need to install a motor or other drive source inside, which would pose a safety hazard. By using the airflow fluctuations brought about by the rising exhaust gas to provide power, existing resources can be used rationally, avoiding energy waste.

[0059] See Figure 3 , Figures 5-8 As shown, in this embodiment, a slot 72 is opened on one side of the fixed frame 7, and a horizontal groove 73 is opened on the side of the groove 71 of the fixed frame 7. The horizontal groove 73, the slot 72 and the groove 71 are interconnected. A baffle 11 is movably arranged in the horizontal groove 73, and a plurality of holes 111 are opened on the baffle 11.

[0060] Specifically, before the fixed frame 7 reaches the flipping position, the grooves 71 are all open upwards, and the baffle 11 is located inside the transverse groove 73, so it does not block the grooves 71, allowing more liquid to enter the grooves 71. When a certain amount of liquid has collected in the grooves 71, and it is about to reach the flipping position, the baffle 11 is moved laterally along the groove opening 72 and the transverse groove 73, so that the baffle 11 seals the grooves 71. During the flipping process, the liquid in the grooves 71 is thrown outwards through the leakage hole 111. If the grooves 71 are open... In the case of liquid spraying, the liquid is directly poured out from the large opening, mostly in the form of large droplets / plates with small specific surface area, resulting in weak mixing. In addition, the liquid is freely thrown out along the opening direction, which is uncontrollable and unevenly distributed, easily forming local liquid columns or large liquid films, resulting in uneven mixing. If the liquid is sprayed outward through the leakage hole 111, the leakage hole 111 will shear, throttle, and tear the liquid, directly breaking the large droplets / liquid films into fine droplets. The fine droplets have a large specific surface area, which allows for more thorough contact with the flue gas, resulting in higher cooling, absorption, and desulfurization efficiency.

[0061] See Figures 5-6 As shown, in this embodiment, a crossbar 12 is rotatably arranged inside the slot 72, and a curved groove 121 is opened on one side of the crossbar 12. The crossbar 12 is located below the baffle 11, and a limiting rod 10 is fixedly arranged at the bottom of the baffle 11. The end of the limiting rod 10 away from the baffle 11 slides and fits against the curved groove 121.

[0062] Specifically, the rotation of the crossbar 12 causes the curved groove 121 to rotate. Since the curved groove 121 is slidably attached to the limiting rod 10, the rotation of the curved groove 121 will cause the limiting rod 10 to move laterally back and forth, thereby causing the baffle 11 to move laterally back and forth, which can realize the baffle 11 blocking and opening the groove 71.

[0063] See Figures 5-6 As shown, in this embodiment, a movable plate 13 is movably arranged on the other side of the slot 72, and a positioning rod 14 is fixedly arranged on the top of the movable plate 13. An arc groove 122 is opened at the end of the crossbar 12 away from the curved groove 121, and the end of the positioning rod 14 away from the movable plate 13 slides and fits against the arc groove 122.

[0064] Specifically, when the movable plate 13 moves towards the groove 71 within the slot 72, it will cause the horizontal bar 12 to rotate via the sliding of the positioning rod 14 along the arc groove 122. The rotation of the horizontal bar 12 will cause the curved groove 121 to rotate, causing the limiting rod 10 and the baffle 11 to move towards the outside of the slot 72 and block the groove 71. Similarly, when the movable plate 13 returns to its initial position, the baffle 11 will not block the groove 71, making it easier for liquid to enter the interior of the groove 71.

[0065] See Figure 4 and Figure 5As shown, in this embodiment, a fixed ring 15 is fixedly installed above the ring 84 in the fixed cylinder 83. A protrusion 16 is provided on the fixed ring 15. A round rod 17 is movably inserted through the inside of the movable rod 6. The round rod 17 moves laterally relative to the movable rod 6 and the two rotate coaxially. One end of the round rod 17 slides and fits against the fixed ring 15 and the protrusion 16. One end of the round rod 17 movably penetrates the fixed frame 7 and is located inside the slot 72. The end of the round rod 17 is fixedly inserted through the movable plate 13.

[0066] Specifically, the rotating rod 4 drives the rotating cylinder 5 to rotate around the fixed cylinder 83 and the fixed ring 15. When the bevel gear 82 on the movable rod 6 is about to mesh with the transmission gear 85, one end of the round rod 17 extends out of the movable rod 6. The extended part rotates along the fixed ring 15 and the protrusion 16. The round rod 17 first moves along the fixed ring 15 towards the protrusion of the protrusion 16. The round rod 17 will then move towards the inside of the movable rod 6. The movement of the movable rod 6 will drive the movable plate 13 to move towards the groove 71 within the slot 72, thus achieving the blocking of the groove 71 by the baffle 11. As the bevel gear... When bevel gear 82 meshes with transmission gear 85, it drives multiple components such as movable rod 6, round rod 17, and fixed frame 7 to rotate synchronously, causing the liquid in groove 71 to be thrown outward through leakage hole 111, thereby increasing the mixing degree of liquid and exhaust gas. Similarly, after bevel gear 82 and transmission gear 85 no longer mesh, fixed frame 7 rotates exactly one revolution, groove 71 opens upward, and round rod 17 moves along the protrusion of protrusion 16 to the surface of fixed ring 15. When round rod 17 is moved in the opposite direction to the initial position, movable plate 13 also moves synchronously, so that baffle 11 no longer blocks groove 71, making it easier to catch the spilled liquid.

[0067] See Figure 5 and Figure 6 As shown, in this embodiment, a connecting plate 18 is fixedly connected to the end of the round rod 17, and the connecting plate 18 is fixedly connected to the inner wall of the slot 72 by a plurality of positioning springs 19.

[0068] Specifically, when the round rod 17 moves toward the inside of the movable rod 6, it will drive the connecting plate 18 to move inside the slot 72, stretching the positioning spring 19; when the round rod 17 moves along the protrusion 16 to the surface of the fixed ring 15, under the action of the positioning spring 19 returning to its original state, it can pull the connecting plate 18 and the round rod 17 to move in the opposite direction to the initial position.

[0069] See Figures 5-8 As shown, in this embodiment, a plurality of vertical slots 74 are linearly arrayed in the groove 71, and a partition 20 is movably disposed in the vertical slot 74. The fixed frame 7 is located below the groove 71 and has a movable slot 75. The movable slot 75 is connected to the vertical slots 74. The bottoms of the plurality of partitions 20 are connected together by a fixed plate 21. The fixed plate 21 moves up and down relative to the movable slot 75, and the bottom of the fixed plate 21 is elastically connected to the inner wall of the movable slot 75.

[0070] Specifically, when the baffle 11 no longer blocks the groove 71, the partition 20 is located inside the vertical groove 74. When the fixed frame 7 is about to flip, the baffle 11 is used to block the groove 71 first. While the baffle 11 moves, the fixed plate 21 moves upward along the movable groove 75. The upward movement of the fixed plate 21 drives multiple partitions 20 to move upward along the vertical groove 74. Part of the partition 20 extends out of the vertical groove 74. The lifting and lowering movement of the partition 20 forces a disturbance to the liquid at the bottom of the groove 71, preventing high-viscosity liquids (such as liquid sulfur) from settling and scaling at the bottom. The disturbance makes the liquid mix more evenly, avoiding unstable throwing effect due to concentration / temperature stratification. Secondly, the process of the partition 20 rising is also a process of shearing, squeezing and tearing the liquid. Large liquid clumps / films that may have been stuck together are broken up by the partition 20, making the contact between the spilled liquid and the exhaust gas higher and improving the purification efficiency of the exhaust gas.

[0071] See Figures 5-9 As shown, in this embodiment, a vertical rod 22 is fixedly installed at the bottom of the fixed plate 21, and a push rod 23 is fixedly installed on one side of the connecting plate 18. A groove 231 is opened on one side of the push rod 23, and the bottom of the vertical rod 22 is movably abutted against the groove 231.

[0072] Specifically, the movement of the connecting plate 18 will cause the push rod 23 to move synchronously, and the vertical rod 22 will move from the lower part of the inclined groove 231 to the upper part. The upward movement of the vertical rod 22 will cause the fixed plate 21 to move upward synchronously, so that the partition plate 20 extends to the outside of the vertical groove 74 to disturb the liquid. Since the bottom of the fixed plate 21 is elastically connected to the inner wall of the movable groove 75, when the push rod 23 moves in the opposite direction to the initial position with the connecting plate 18, the fixed plate 21, the vertical rod 22 and the partition plate 20 will move downward to the initial position due to the loss of the push rod 23's abutment.

[0073] See Figure 7 As shown, in this embodiment, the fixing frame 7 has a receiving groove 76 on one side of the groove 71, and a plurality of impact balls 24 are provided in the receiving groove 76.

[0074] Specifically, during the rotation and flipping of the fixed frame 7, the impact ball 24 moves within the receiving tank 76 under the action of centrifugal force, gravity, and inertia, repeatedly impacting the inner wall of the receiving tank 76, generating high-frequency, continuous micro-vibrations. This vibration is transmitted to the groove 71 area through the fixed frame 7 body, breaking the static layer of liquid at the bottom of the groove 71 and preventing the liquid from stagnating and caking due to high viscosity.

[0075] In this embodiment, a carbon disulfide preliminary separation tower includes the above-mentioned spray cooling mechanism.

[0076] Specifically, a carbon disulfide preliminary separation tower, in addition to the above-mentioned spray cooling mechanism, can also add a packing layer inside, so that the sprayed liquid forms a liquid film on its surface, and the waste gas comes into full contact with the liquid film when passing through the packing, so as to achieve the absorption, washing and cooling of pollutants.

[0077] 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.

[0078] 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.
