Description

Technical Field

[0001] This utility model belongs to the field of glycerin production technology, and in particular relates to a glycerin purification tail gas treatment device. Background Technology

[0002] Glycerol purification processes generate tail gases. During glycerol purification, particularly in the crude glycerol distillation process, tail gases containing volatile organic compounds (VOCs) are produced. These tail gases primarily consist of HCl and VOCs and are typically purified using an alkaline scrubbing tower.

[0003] Existing spray towers can only spray exhaust gas during absorption. However, some exhaust gas will always be sprayed but not completely. Therefore, multiple spray towers are needed for cyclic spraying to complete the purification of exhaust gas. As a result, the exhaust gas treatment effect of a single spray tower is not thorough and efficient enough. To address this, we propose a glycerol purification exhaust gas treatment device. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to provide a glycerol purification tail gas treatment device.

[0005] To achieve the above objectives, this utility model proposes a glycerol purification tail gas treatment device, including an absorption tower. An inlet pipe is fixedly fitted onto one side of the absorption tower. One end of the inlet pipe, extending into the absorption tower, is fixedly connected to a spray pipe communicating with it. Below the spray pipe is an air intake absorption assembly, which sends the tail gas into the absorption tower for rotational blowing. The air intake absorption assembly includes an air intake fixed pipe fixedly fitted onto one side of the absorption tower. One end of the air intake fixed pipe, extending into the absorption tower, is fixedly connected to a connector. A connector sleeve is movably fitted onto the outside of the connector. A T-shaped tube is fixedly connected to the top of the connector sleeve. An outlet pipe communicating with the T-shaped tube is fixedly connected to it. A vertical shaft is fixedly connected between the T-shaped tubes. Multiple first perforated plates are arrayed on the vertical shaft. A second perforated plate is fixedly connected to the top of the vertical shaft. A driven bevel gear is fixedly fitted onto the outside of the T-shaped tube. A driving vibration assembly is provided on the absorption tower, which not only drives the air intake absorption assembly to rotate but also causes it to vibrate.

[0006] Preferably, the driving vibration assembly includes a fixed plate fixedly connected to the outer wall of the absorption tower, a drive motor fixedly connected to the fixed plate, a first rotating shaft fixedly connected to the output shaft of the drive motor, a driving bevel gear fixedly connected to one end of the first rotating shaft extending into the absorption tower, and the driving bevel gear meshing with the driven bevel gear for transmission, a second rotating shaft movably sleeved on the absorption tower, a cam fixedly connected to one end of the second rotating shaft extending into the absorption tower, and the cam intermittently contacting the second mesh plate, pulleys fixedly sleeved on the outside of both the first and second rotating shafts, and belts sleeved on the outside of the two pulleys.

[0007] Preferably, an exhaust pipe is fixedly connected to the top of the absorption tower, and a drain pipe is fixedly connected to the bottom of the absorption tower, with a valve installed on the drain pipe.

[0008] Preferably, the absorption tower has a first mounting hole and a second mounting hole on its left side, the liquid inlet pipe is sealed and fitted inside the first mounting hole, and the air inlet fixed pipe is sealed and fitted inside the second mounting hole.

[0009] Preferably, the absorption tower has two movable holes on its right side, and a sealing sleeve is fitted inside the movable holes, with both the first and second rotating shafts movably fitted inside the sealing sleeve.

[0010] Preferably, the bottom array of the absorption tower is provided with multiple support plates.

[0011] The glycerol purification exhaust gas treatment device proposed in this utility model can bring the following beneficial effects:

[0012] 1. The exhaust gas is blown out of the absorption tower by rotating the air intake absorption component, which speeds up the flow of the exhaust gas. At the same time as the air is blown out, the first mesh plate and the second mesh plate are also rotated. The liquid film in the mesh of the first mesh plate and the second mesh plate will come into contact with the exhaust gas and be absorbed.

[0013] 2. By driving the vibration component, not only can the intake absorption component be rotated, but the intake absorption component can also be struck to generate vibration. When the first and second mesh plates vibrate, the mesh holes are cleared, preventing impurities in the exhaust gas from clogging the mesh holes.

[0014] In summary, this scheme has a simple structure and novel design. It can not only rotate to blow air, which is beneficial to the flow of exhaust gas, but also drive the first and second mesh plates to contact the exhaust gas with the liquid film in the mesh, thereby improving the absorption efficiency of the exhaust gas. In addition, it vibrates the mesh to prevent impurities from clogging the mesh, which is conducive to the high-efficiency absorption of the absorption tower. Attached Figure Description

[0029] like Figures 1-6As shown in the figure, an embodiment of this utility model proposes a glycerol purification tail gas treatment device, including an absorption tower 1. An inlet pipe 2 is fixedly sleeved on one side of the absorption tower 1. One end of the inlet pipe 2, extending into the absorption tower 1, is fixedly connected to a spray pipe 3 communicating with it. Below the spray pipe 3 is an air intake absorption assembly 4. This air intake absorption assembly 4 sends the tail gas into the absorption tower 1 for rotating air blowing. The air intake absorption assembly 4 includes an air intake fixing pipe 401 fixedly sleeved on one side of the absorption tower 1. One end of the air intake fixing pipe 401, extending into the absorption tower 1, is fixedly connected to a connector 402. The connector 402... The external movable sleeve is equipped with a plug sleeve 403, and a T-shaped tube 404 is fixedly connected to the top of the plug sleeve 403. An air outlet pipe 405 is fixedly connected to the T-shaped tube 404 and communicates with it. A vertical shaft 406 is fixedly connected between the T-shaped tubes 404. Multiple first mesh plates 407 are arrayed on the vertical shaft 406. A second mesh plate 408 is fixedly connected to the top of the vertical shaft 406. A driven bevel gear 409 is fixedly sleeved on the outside of the T-shaped tube 404. A driving vibration assembly 5 is provided on the absorption tower 1. The driving vibration assembly 5 not only drives the air intake absorption assembly 4 to rotate but also drives it to vibrate.

[0030] like Figure 5 and Figure 6 As shown, the driving vibration assembly 5 includes a fixed plate 501 fixedly connected to the outer wall of the absorption tower 1. A drive motor 502 is fixedly connected to the fixed plate 501. The output shaft of the drive motor 502 is fixedly connected to a first rotating shaft 503. One end of the first rotating shaft 503 extending into the absorption tower 1 is fixedly connected to a driving bevel gear 504, and the driving bevel gear 504 meshes with a driven bevel gear 409 for transmission. A second rotating shaft 505 is movably sleeved on the absorption tower 1. One end of the second rotating shaft 505 extending into the absorption tower 1 is fixedly connected to a cam 506, and the cam 506 intermittently contacts the second mesh plate 408. The first rotating shaft 503 and the second rotating shaft 505 are both fixedly fitted with pulleys 507, and belts 508 are fitted on the outside of the two pulleys 507. The drive motor 502 drives the first rotating shaft 503 to rotate. The first rotating shaft 503 drives the T-shaped tube 404 to rotate through the active bevel gear 504 and the driven bevel gear 409, thereby driving the entire air intake absorption assembly 4 to rotate. The first rotating shaft 503 also drives the second rotating shaft 505 to rotate through the pulleys 507 and the belts 508. The second rotating shaft 505 drives the cam 506 to rotate, so the cam 506 will drive the air intake absorption assembly 4 to vibrate.

[0031] like Figure 1 As shown, an exhaust pipe 6 is fixedly connected to the top of the absorption tower 1, and a drain pipe 7 is fixedly connected to the bottom of the absorption tower 1. A valve is provided on the drain pipe 7. The purified gas is discharged from the exhaust pipe 6, and the absorbent liquid that absorbs the tail gas is discharged from the drain pipe 7.

[0032] like Figure 2As shown, the absorption tower 1 has a first mounting hole and a second mounting hole on its left side. The liquid inlet pipe 2 is sealed in the first mounting hole, and the gas inlet fixed pipe 401 is sealed in the second mounting hole.

[0033] like Figure 3 As shown, two movable holes are opened on the right side of the absorption tower 1. A sealing sleeve is fitted inside the movable hole, and the first rotating shaft 503 and the second rotating shaft 505 are both movably fitted inside the sealing sleeve.

[0034] like Figure 1 As shown, the bottom array of the absorption tower 1 is provided with multiple support plates.

[0035] Working principle: Exhaust gas is blown in through the intake fixed pipe 401, passes through the connector 402, connector sleeve 403, and T-shaped pipe 404, and then exits through the exhaust pipe 405. Meanwhile, the drive motor 502 drives the first rotating shaft 503 to rotate. The first rotating shaft 503, through the driving bevel gear 504 and driven bevel gear 409, drives the T-shaped pipe 404 to rotate, which in turn drives the exhaust pipe 405, vertical shaft 406, first mesh plate 407, and second mesh plate 408 to rotate. The rotation of the exhaust pipe 405 facilitates airflow, while the absorbent liquid flows from the inlet pipe 2... The absorbent enters the spray pipe 3, and finally the spray pipe 3 atomizes and sprays the absorbent from the top downwards. The absorbent forms a liquid film in the mesh of the first mesh plate 407 and the second mesh plate 408. When the exhaust gas comes into contact with the liquid film, it will be absorbed. The first rotating shaft 503 also drives the second rotating shaft 505 to rotate through the pulley 507 and the belt 508. The second rotating shaft 505 drives the cam 506 to rotate. In this way, the cam 506 will drive the first mesh plate 407 and the second mesh plate 408 to vibrate, thereby avoiding the mesh from being blocked by impurities and affecting the passage of exhaust gas.
