Description

Technical Field

[0001] This invention relates to the field of carbon product manufacturing technology, and in particular to a waste gas treatment device for carbon product demolding and molding. Background Technology

[0002] The carbon molding process generates a large amount of waste gas, which includes asphalt fumes, dust, water vapor, and VOCs. Therefore, the waste gas needs to be treated before it can be discharged, otherwise it will pollute the environment.

[0003] Currently, the main methods for treating the aforementioned waste gases fall into two categories: physical filtration using filter materials or physical adsorption using activated carbon filters. These two types of waste gas treatment devices have simple structures and good waste gas purification effects, but the filters are prone to clogging and need to be replaced frequently. Because the waste gases contain a large amount of pollutants such as solid particulate matter and organic matter, and the waste gases are too dirty, the frequency of filter replacement is high, which is time-consuming and labor-intensive, and seriously affects the treatment efficiency of the waste gas treatment device.

[0004] Furthermore, although some exhaust gas treatment devices have added spray equipment, such as the patent application number CN202210475420.X, which sprays water mist into the exhaust gas to wet the solid particles and impurities, increasing their diameter and weight so that they fall into the collection box without being filtered by the filter screen, thereby reducing filter screen clogging and extending the filter screen's service life, spraying water mist into the exhaust gas cannot guarantee that all solid particles and impurities in the exhaust gas will be wetted and fall into the collection box. A sufficient number of solid particles and impurities in the exhaust gas will still not fall into the collection box, and these solid particles and impurities will still clog the filter screen. Therefore, exhaust gas treatment devices with added spray equipment cannot significantly improve the frequency of filter screen replacement or effectively extend the service life of the filter screen. Summary of the Invention

[0005] The main objective of this invention is to propose a waste gas treatment device for carbon fiber demolding, which aims to solve the problem that existing waste gas treatment devices for carbon fiber demolding require frequent filter replacements during operation, which is time-consuming, labor-intensive, and affects waste gas treatment efficiency.

[0006] To address the above problems, this invention proposes a waste gas treatment device for carbon fiber demolding, comprising:

[0007] The centrifuge block has an annular rich-material cavity on its lower surface and an air inlet on its upper surface. The air inlet and the annular rich-material cavity are connected through a centrifugal air passage. The centrifuge block is connected to a motor drive and is driven to rotate by the motor.

[0008] A storage cylinder is located on the lower surface of the centrifuge block and is coaxially and rotaryly sealed with the centrifuge block. A gas guide cylinder is coaxially fixed inside the storage cylinder. The lower end of the gas guide cylinder penetrates the bottom of the storage cylinder. The gas guide cylinder defines an annular storage cavity inside the storage cylinder. The solid matter in the annular storage cavity falls into the annular storage cavity under its own weight. The gas in the annular storage cavity enters the storage cylinder and escapes from the lower end of the gas guide cylinder.

[0009] An absorption basin containing an absorption liquid, wherein the lower surface of the storage cylinder is below the surface of the absorption liquid.

[0010] In one embodiment, the air inlet, the annular rich-material chamber, and the centrifuge block are all coaxial with the rotation axis of the centrifuge block;

[0011] The centrifuge block is cylindrical, and the centrifuge air passages extend radially along the centrifuge block. There are multiple centrifuge air passages, which are arranged in a ring array around the rotation axis of the centrifuge block.

[0012] In one embodiment, a gear ring is coaxially fixed to the outside of the centrifugal block, a drive wheel is provided on the output shaft of the motor, the drive wheel meshes with the gear ring, and the motor is fixedly connected to the storage cylinder.

[0013] In one embodiment, a second air guide ring is coaxially fixed to the upper end of the air guide cylinder. The second air guide ring and the lower surface of the centrifugal block are spaced apart, thereby defining an air guide cavity within the storage cylinder. The second air guide ring and the inner wall of the storage cylinder are spaced apart, thereby defining an annular material guide cavity within the storage cylinder. The air guide cavity and the annular storage cavity are located on the upper and lower sides of the second air guide ring, respectively. The air guide cavity and the annular storage cavity are connected through the annular material guide cavity. The annular material guide cavity is located directly below the annular rich material cavity. The solid material in the annular rich material cavity falls into the annular storage cavity through the annular material guide cavity under its own weight.

[0014] In one embodiment, the outer sealing sleeve of the storage cylinder is provided with a first air guide ring. The first air guide ring is fixedly connected to the inner wall of the absorption basin. The first air guide ring is located below the liquid surface of the absorption liquid. The lower surface of the first air guide ring is a conical surface. The gas escaping from the lower end of the air guide cylinder moves along the conical surface in the absorption liquid and approaches the inner wall of the absorption basin. The outer diameter edge of the first air guide ring is provided with a plurality of centrally symmetrically distributed air holes. The gas that moves along the conical surface to the inner wall of the absorption basin passes through the air holes and escapes from the absorption liquid.

[0015] In one embodiment, a rotating plate is coaxially spaced below the storage cylinder, and multiple blades are provided on the edge of the rotating plate. A drive shaft is coaxially inserted through the air guide cylinder, and the two ends of the drive shaft are respectively connected to a centrifugal block and a rotating plate. The rotating plate drives the blades to rotate and form an annular liquid-free zone in the absorbent liquid below the air guide ring, thereby preventing the absorbent liquid from entering the air guide cylinder.

[0016] In one embodiment, a base plate is coaxially disposed on the upper surface of the rotating plate, the base plate and the storage cylinder are spaced apart and fixedly connected by a column, and the gap between the base plate and the storage cylinder is filled with a filter pad.

[0017] In one embodiment, the outer sealing sleeve of the storage cylinder is provided with a third air guide ring. The third air guide ring is fixedly connected to the inner wall of the absorption basin. The third air guide ring is located below the liquid surface of the absorption liquid and is located above the first air guide ring, and is spaced apart from the first air guide ring. The lower surface of the third air guide ring is a conical surface. The inclination direction of the conical surface of the third air guide ring is opposite to the inclination direction of the conical surface of the first air guide ring. After passing through the air hole on the first air guide ring upward, the gas moves along the conical surface of the third air guide ring in the absorption liquid and approaches the outer wall of the storage cylinder. The inner diameter edge of the third air guide ring is provided with a plurality of centrally symmetrically distributed air holes. After moving along the conical surface of the third air guide ring to the outer wall of the storage cylinder, the gas passes through the air hole of the third air guide ring upward and escapes from the absorption liquid.

[0018] In one embodiment, a sealing ring is provided between the lower surface of the centrifuge block and the upper surface of the storage cylinder.

[0019] In one embodiment, an installation hole is provided on the wall of the air intake end of the air intake port. The installation hole is coaxial with the air intake port, and the diameter of the installation hole is larger than that of the air intake port. An installation ring is axially slidably installed in the installation hole. The installation ring is tightly sealed on the air intake pipe. A screw cylinder is also fitted on the air intake pipe. The screw cylinder is screwed and fixedly connected to the installation hole. Thrust bearings are provided between the installation ring and the screw cylinder, and between the installation ring and the bottom of the installation hole. A second sealing ring is provided between the installation ring and the thrust bearings on its upper and lower sides.

[0020] Beneficial effects: The waste gas treatment device for carbon fiber demolding of the present invention first centrifuges the waste gas to separate the gas phase, liquid phase and solid phase. After the liquid phase and solid phase are enriched, they fall into the annular storage cavity under their own weight, while the gas phase escapes from the lower end of the gas guide tube and enters the absorbent liquid. The absorbent liquid absorbs the harmful gases (including VOCs organic waste gas). Finally, the gas escaping from the absorbent liquid is harmless to the environment. In the whole process, the waste gas achieves solid-liquid-gas three-phase separation through centrifugation. Therefore, compared with conventional waste gas treatment devices, it saves the trouble of laying filter screens. Thus, there is no need to frequently replace filter screens, saving time and effort, and the waste gas treatment efficiency is high. Attached Figure Description

[0037] This invention proposes a waste gas treatment device for carbon fiber demolding. This waste gas treatment device first centrifuges the waste gas to separate the gas, liquid, and solid phases. The liquid and solid phases are enriched and fall into the annular storage cavity 73 under their own weight, while the gas phase escapes from the lower end of the gas guide tube 71 into the absorbent liquid. The absorbent liquid absorbs harmful gases (including VOCs organic waste gas). Finally, the gas escaping from the absorbent liquid is harmless to the environment. In the whole process, the waste gas achieves solid-liquid-gas three-phase separation through centrifugation. Therefore, compared with conventional waste gas treatment devices, it saves the trouble of laying filter screens and does not need to frequently replace filter screens, saving time and effort and achieving high waste gas treatment efficiency.

[0038] Specifically, in one embodiment of the invention, the waste gas treatment device for carbon fiber demolding includes a centrifugal block 17, a storage cylinder 7, and an absorption basin 1, as shown below. Figures 1-5 As shown, the lower surface of the centrifuge block 17 is provided with an annular enrichment cavity 19, and the upper surface of the centrifuge block 17 is provided with an air inlet 20. Preferably, the air inlet 20, the annular enrichment cavity 19, and the centrifuge block 17 are all coaxial with the rotation axis of the centrifuge block 17, and the centrifuge block 17 is cylindrical. This design facilitates the achievement of excellent centrifugation effect for the exhaust gas.

[0039] In this embodiment, as Figures 1-5 As shown, the air inlet 20 and the annular rich-material cavity 19 are connected by a centrifugal air passage 21. Preferably, the centrifugal air passage 21 extends radially along the centrifugal block 17. This design facilitates excellent centrifugal effect for the waste gas. There are multiple centrifugal air passages 21, which are arranged in a ring array around the rotation axis of the centrifugal block 17. This design facilitates the uniform distribution of the waste gas entering the air inlet 20 in each centrifugal air passage 21, quickly completing the centrifugal treatment of the waste gas and improving the speed and efficiency of waste gas centrifugal treatment.

[0040] In this embodiment, the centrifuge block 17 is connected to the motor 14 for transmission, and the motor 14 drives the centrifuge block 17 to rotate. Preferably, as shown in the following example... Figure 2 and Figure 3 As shown, a gear ring 16 is coaxially fixed to the outside of the centrifugal block 17, and a drive wheel 15 is provided on the output shaft of the motor 14. The drive wheel 15 meshes with the gear ring 16. The motor 14 is fixedly connected to the storage cylinder 7, and the drive wheel 15 is a gear.

[0041] In this embodiment, the air inlet 20 is rotatably and sealed to the air inlet pipe 24. Waste gas is injected into the air inlet 20 through the air inlet pipe 24. The design of the air inlet 20 and the air inlet pipe 24 being rotatably and sealed together means that the air inlet pipe 24 does not need to rotate with the centrifugal block 17, so that the injection of waste gas into the air inlet 20 through the air inlet pipe 24 can be carried out smoothly.

[0042] Specifically, the structure in which the air inlet 20 is rotary sealed to the air inlet pipe 24 is as follows: Figures 1-4 As shown, the intake port 20 has an installation hole 22 on its intake end wall. The installation hole 22 is coaxial with the intake port 20, and the diameter of the installation hole 22 is larger than that of the intake port 20. An installation ring 23 is axially slidably installed in the installation hole 22. The installation ring 23 is tightly sealed on the intake pipe 24 and detachably fixedly connected to the intake pipe 24. A screw cylinder 25 is also fitted on the intake pipe 24. The screw cylinder 25 is screwed and fixedly connected to the installation hole 22. This design allows the installation ring 23 to be pressed and fixed to the bottom of the installation hole 22 by rotating the screw cylinder 25, thereby fixing the intake pipe 24 and preventing the intake pipe 24 from moving axially and interfering with the intake port 20. To prevent slippage and separation, thrust bearings 26 are provided between the mounting ring 23 and the screw cylinder 25, and between the mounting ring 23 and the bottom of the mounting hole 22. The design of the thrust bearings 26 ensures that the air inlet 20 can rotate relative to the air inlet pipe 24 without affecting the installation firmness of the air inlet pipe 24, and prevents the air inlet pipe 24 from axially moving and slipping away from the air inlet 20. At the same time, sealing rings 27 are provided between the mounting ring 23 and the thrust bearings 26 on its upper and lower sides. The rubber sealing rings 27 seal the upper and lower sides of the mounting ring 23, and together with the thrust bearings 26, they achieve a rotary and sealed connection between the air inlet 20 and the air inlet pipe 24.

[0043] In this embodiment, as Figures 1-3 As shown, the storage cylinder 7 is located on the lower surface of the centrifugal block 17 and is coaxially and rotaryly sealed with the centrifugal block 17. For example, a sealing ring 18 is provided between the lower surface of the centrifugal block 17 and the upper surface of the storage cylinder 7, and the two are rotaryly sealed together by the sealing ring 18.

[0044] In this embodiment, as Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, a guide cylinder 71 is coaxially fixed inside the storage cylinder 7. The lower end of the guide cylinder 71 penetrates the bottom of the storage cylinder 7, and the guide cylinder 71 defines an annular storage cavity 73 inside the storage cylinder 7. After the exhaust gas is injected into the air inlet 20 by the air inlet pipe 24, the exhaust gas enters each centrifugal air channel 21. The centrifugal block 17 rotates at high speed under the drive of the motor 14, causing the exhaust gas in the centrifugal air channel 21 to rotate synchronously, thereby centrifuging the exhaust gas in the centrifugal air channel 21. According to the different masses of the gas, liquid, and solid three-phase substances, the centrifugal force they are subjected to is also different, thus realizing... In the solid-liquid-gas three-phase separation, the gas and liquid phases in the waste gas rapidly impact the inner wall of the annular enrichment cavity 19 and accumulate there. After accumulation, the liquid and solid phases fall into the annular storage cavity 73 under their own weight. The annular storage cavity 73 has a large volume and can temporarily store a large amount of liquid and solid phases. Therefore, the waste gas treatment device for carbon demolding molding in this embodiment only needs to periodically disassemble the separation centrifugal block 17 and the storage cylinder 7 to clean the liquid and solid phases in the annular storage cavity 73. The cleaning cycle is long, which saves time and effort compared to the frequent replacement of filter screens in the prior art and does not affect the waste gas treatment efficiency.

[0045] Furthermore, such as Figure 2 , Figure 3 , Figure 6 As shown, a second air guide ring 72 is coaxially fixed at the upper end of the air guide cylinder 71. The second air guide ring 72 and the lower surface of the centrifugal block 17 are spaced apart, thereby defining an air guide cavity 74 within the storage cylinder 7. The presence of the air guide cavity 74 facilitates the smooth flow of gas from the annular rich cavity 19 into the air guide cylinder 71, and finally escapes from the lower end of the air guide cylinder 71 and leaves the storage cylinder 7. In addition, the design of the second air guide ring 72 can also effectively prevent the liquid and solid phases in the annular storage cavity 73 from flowing out and entering the air guide cylinder 71. Figure 2 and Figure 3 As shown, the second air guide ring 72 and the inner wall of the storage cylinder 7 are spaced apart, thereby defining an annular guide cavity 75 within the storage cylinder 7. The air guide cavity 74 and the annular storage cavity 73 are located on the upper and lower sides of the second air guide ring 72, respectively. The air guide cavity 74 and the annular storage cavity 73 are connected through the annular guide cavity 75. The annular guide cavity 75 is located directly below the annular rich cavity 19. With this design, the solid material in the annular rich cavity 19 will fall into the annular storage cavity 73 through the annular guide cavity 75 under its own weight. The liquid and solid phases in the annular storage cavity 73 cannot flow out into the air guide cylinder 71.

[0046] In this embodiment, as Figures 1-3As shown, the absorption basin 1 contains an absorbent liquid, which is formulated according to the gas phase composition of the waste gas and is specifically used to absorb harmful gases in the waste gas. For example, when the waste gas contains a large amount of VOCs organic waste gas or asphalt gas, the composition of the absorbent liquid should include at least water, high-boiling-point organic solvent, composite absorbent, and inorganic additives. In actual production, the specific composition of the absorbent liquid can be formulated according to the gas phase composition of the waste gas.

[0047] In this embodiment, as Figure 2 and Figure 3 As shown, the lower surface of the storage cylinder 7 is below the liquid surface of the absorbent. With this design, the gas escaping from the lower end of the gas guide cylinder 71 and leaving the storage cylinder 7 enters the absorbent. The absorbent absorbs the harmful substances in the gas phase, and the gas that finally escapes from the absorbent is harmless to the environment.

[0048] As can be seen, the exhaust gas treatment device for carbon fiber demolding in this embodiment achieves solid-liquid-gas three-phase separation during the entire exhaust gas treatment process because the exhaust gas is centrifuged. There is no need to set up a filter screen for separation and filtration. Therefore, compared with conventional exhaust gas treatment devices, it saves the trouble of setting up a filter screen and does not need to replace the filter screen frequently, saving time and effort. The solid and liquid phases are stored in the annular storage cavity 73, and the harmful substances in the gas phase are absorbed by the absorbent liquid. Thus, the gas discharged by the exhaust gas treatment device for carbon fiber demolding in this embodiment is harmless. Without the trouble of frequently replacing the filter screen, the exhaust gas treatment efficiency is significantly improved.

[0049] Furthermore, in order to prolong the residence time of the gas phase in the absorbent, such as... Figures 1-3 , Figure 9 As shown, the storage cylinder 7 is fitted with a gas guide ring 2 on its outer sealing sleeve. The gas guide ring 2 is fixedly connected to the inner wall of the absorption basin 1. The gas guide ring 2 is located below the liquid surface of the absorption liquid. The lower surface of the gas guide ring 2 is a conical surface 3. This design allows the gas escaping from the lower end of the gas guide cylinder 71 to move along the conical surface 3 towards the inner wall of the absorption basin 1 in the absorption liquid, thereby greatly prolonging the time of the gas phase in the absorption liquid. This allows the absorption liquid to fully absorb harmful substances in the gas phase, ensuring that the gas escaping from the absorption liquid is harmless to the environment. Correspondingly, such as Figures 1-3 As shown, the outer diameter edge of the gas guide ring 2 is provided with a plurality of centrally symmetrically distributed air holes 4. The gas that moves along the conical surface 3 to the inner wall of the absorption basin 1 passes through the air holes 4 and escapes from the absorption liquid.

[0050] Furthermore, such as Figures 1-3 , Figure 9As shown, the storage cylinder 7 is further sealed with a third air guide ring 29. The third air guide ring 29 is fixedly connected to the inner wall of the absorption basin 1. The third air guide ring 29 is located below the liquid surface of the absorption liquid and above the first air guide ring 2, and is spaced apart from the first air guide ring 2. The lower surface of the third air guide ring 29 is a conical surface 3. The inclination direction of the conical surface 3 of the third air guide ring 29 is opposite to the inclination direction of the conical surface 3 of the first air guide ring 2, and it extends upward through the air hole 4 on the first air guide ring 2. In the absorbent liquid, the gas moves along the conical surface 3 of the gas guide ring 29 towards the outer wall of the storage cylinder 7. The inner diameter edge of the gas guide ring 29 has multiple centrally symmetrically distributed air holes 4. Gas moving along the conical surface 3 of the gas guide ring 29 to the outer wall of the storage cylinder 7 passes through the air holes 4 of the gas guide ring 29 and escapes from the absorbent liquid. This design further prolongs the time the gas phase spends in the absorbent liquid, allowing the absorbent liquid to fully absorb harmful substances in the gas phase and ensuring that the gas escaping from the absorbent liquid is environmentally harmless. Furthermore, multiple gas guide rings 2 and 3 can be provided, and they can be arranged alternately on the storage cylinder 7 to further prolong the time the gas phase spends in the absorbent liquid.

[0051] In this embodiment, in order to allow the gas to escape very easily from the lower end of the gas guide tube 71, such as Figure 2 and Figure 3 As shown, rotating plates 11 are coaxially spaced below the storage cylinder 7. This spacing does not obstruct the gas from escaping from the lower end of the gas guide cylinder 71 into the absorption liquid. Figure 6 As shown, the edge of the rotating plate 11 is provided with multiple blades 12, such as... Figure 2 and Figure 3 As shown, a drive shaft 13 is coaxially installed through the air guide cylinder 71. The two ends of the drive shaft 13 are connected to a centrifugal block 17 and a rotating plate 11, respectively. The centrifugal block 17 can drive the rotating plate 11 to rotate at high speed synchronously via the drive shaft 13. With this design, the rotating plate 11 drives the blades 12 to rotate, forming an annular liquid-free zone 6 in the absorbent liquid below the air guide ring 2. Figure 3As shown, this design prevents the absorbent liquid from entering the air guide tube 71, thus preventing the gas from easily escaping from the lower end of the air guide tube 71. When the absorbent liquid enters the air guide tube 71, the gas needs sufficient pressure to overcome the pressure of the absorbent liquid in order to escape from the lower end of the air guide tube 71. Therefore, the gas cannot easily escape from the lower end of the air guide tube 71. A rotating plate 11 is set up, which drives the blade 12 to rotate and rotate the absorbent liquid, thereby forming an annular liquid-free zone 6 in the absorbent liquid below the air guide ring 2. This prevents the absorbent liquid from entering the air guide tube 71, so the gas can easily escape from the lower end of the air guide tube 71 and enter the annular liquid-free zone 6. Under the action of buoyancy, the gas entering the annular liquid-free zone 6 can easily move along the conical surface 3 towards the inner wall of the absorption basin 1, and the gas can easily escape from the lower end of the air guide tube 71, which is beneficial to accelerating the waste gas treatment efficiency.

[0052] In this embodiment, as Figure 2 , Figure 3 , Figures 6-8 As shown, a base plate 10 is coaxially arranged on the upper surface of the rotating plate 11. The base plate 10 and the storage cylinder 7 are spaced apart and fixedly connected by a column 8. The rotating plate 11 and the base plate 10 are slidably connected. This design facilitates the filling of a filter pad 9 in the gap 28 between the base plate 10 and the storage cylinder 7. The filter pad 9 performs secondary filtration of the gas phase (centrifugal separation of waste gas is equivalent to primary filtration), ensuring that the gas phase entering the absorption liquid is free of solid and liquid phases, and ensuring that the gas escaping from the absorption liquid is harmless to the environment.

[0053] In this embodiment, when the centrifuge block 17 is not rotating, the liquid level 5 of the absorbent liquid in the absorption basin 1 is as follows: Figure 2 As shown, during the high-speed rotation of the centrifuge block 17, the liquid level 5 of the absorbent liquid in the absorption basin 1 is as follows: Figure 3 As shown.

[0054] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.

This prevents the absorbent liquid from entering the gas guide cylinder, allowing gas to escape from the lower end of the gas guide cylinder and enter the annular liquid-free zone. Under the action of buoyancy, the gas in the annular liquid-free zone can move along the conical surface towards the inner wall of the absorption basin, and the gas can escape from the lower end of the gas guide cylinder.
