Description

Technical Field

[0001] This application relates to the field of gas treatment, and more particularly to a separation device and an exhaust gas treatment system. Background Technology

[0002] The coating process is an important part of the solar cell production process. After the coating process, the exhaust gas generated in the process is sent to the exhaust gas system through the pipeline for treatment, and is released into the atmosphere when it meets the emission standards.

[0003] However, the exhaust gas contains a large number of solid particles and water mist. During the transportation of the exhaust gas through the pipeline, the solid particles and water mist in the exhaust gas will accumulate in the pipeline, resulting in a large amount of dust and water accumulation in the pipeline. This will reduce the cross-sectional area of ​​the pipeline, and in severe cases, it will completely block the pipeline, causing the transportation to be interrupted. The exhaust gas cannot be sent into the exhaust gas system, which will lead to the shutdown of the production equipment and affect the production efficiency of the production equipment.

[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0049] In this application, the terms "upper," "lower," "left," "right," "top," "bottom," "inner," "outer," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0050] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0051] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts.

[0052] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0053] The electroplating process for solar cells generates a large amount of exhaust gas, primarily from the evaporation of the electroplating solution, gases produced during electrolysis, and potential heating processes. This exhaust gas may contain toxic and harmful substances such as volatile organic compounds, acidic gases, heavy metal vapors, and possibly ozone. Therefore, the exhaust gas from the electroplating equipment must be treated to meet emission standards before being released into the atmosphere. Releasing untreated exhaust gas into the atmosphere will pollute the environment and harm human health.

[0054] In related technologies, exhaust gas emitted from production equipment is directly transported through pipelines to an exhaust gas treatment device for processing. After treatment, the exhaust gas meets emission standards before being released into the atmosphere through a chimney. However, the exhaust gas emitted from production equipment contains a large amount of solid dust particles and water mist. These solid dust particles and water mist will accumulate in the pipeline, reducing the cross-sectional area of ​​the pipeline and decreasing its transport capacity. After prolonged use, the pipeline will become blocked by solid dust particles and water mist, preventing the exhaust gas from entering the exhaust gas treatment device, thus causing an interruption in exhaust gas transport and ultimately leading to production machine downtime.

[0055] Based on this, this application discloses a separation device that separates solid dust particles and water mist from the exhaust gas discharged from the production equipment, and then discharges the separated gas, which does not contain dust particles and water mist, into a conveying pipeline for subsequent exhaust gas treatment. This avoids the conveying pipeline from being blocked by solid dust particles and water mist, and ensures the normal operation of the production equipment.

[0056] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0057] Please see Figure 1 and Figure 2 , Figure 1 This is a front view of the separation device 100 disclosed in the embodiments of this application. Figure 2 This is a side view of the separation device 100 disclosed in an embodiment of this application. In a first aspect, an embodiment of this application discloses a separation device 100, specifically, the separation device 100 includes an outer barrel 1, an inner barrel 2, an air inlet pipe 3, and an air outlet pipe 7. The outer barrel 1 has a first cavity 10, the inner barrel 2 is disposed within the first cavity 10, the inner barrel 2 has a second cavity 20, and the inner barrel 2 also has an outlet. The outlet of the inner barrel 2 communicates with the first cavity 10, and the air inlet pipe 3 communicates with the second cavity 20, with the inlet of the air inlet pipe 3 facing the barrel wall 21 of the inner barrel 2. That is, the inner barrel 2 is disposed within the first cavity 10 of the outer barrel 1 and connected to the outer barrel 1, while the air inlet pipe 3 extends from the side wall of the outer barrel 1 into the first cavity 10 and communicates with the second cavity 20 of the inner barrel 2, with the inlet of the air inlet pipe 3 facing the barrel wall 21 of the inner barrel 2, and the air outlet pipe 7 communicates with the first cavity 10.

[0058] It should be noted that the separation device 100 can not only treat exhaust gas, but also other gases to separate solid dust particles and water mist from the gas. This embodiment does not limit this. The following description of the technical solution takes exhaust gas as an example.

[0059] In this way, the inlet of the air inlet pipe 3 is positioned facing the wall 21 of the inner drum 2. When the exhaust gas enters the inner drum 2 through the air inlet pipe 3, it spirals upward along the wall 21 of the inner drum 2. This spiral upward movement of the exhaust gas generates centrifugal force. Therefore, when the exhaust gas spirals upward to the outlet of the inner drum 2, the solid dust particles and water mist in the exhaust gas are separated under the action of centrifugal force and thrown onto the side wall 11 of the outer drum 1. The exhaust gas separated from solid dust particles and water mist continues to spiral upward. This achieves the separation of solid dust particles and water mist from the exhaust gas, preventing the exhaust gas from clogging the pipeline due to solid dust particles and water mist after being discharged into the pipeline, which could lead to the shutdown of the production equipment.

[0060] In some embodiments, such as Figure 1 and Figure 2 As shown, the inlet of the intake pipe 3 is positioned perpendicular to the axis of the inner barrel 2 and faces the barrel wall 21 of the inner barrel 2. This design ensures that the exhaust gas in the intake pipe 3 enters the second cavity 20 of the inner barrel 2 directly and efficiently, reducing obstruction and diffusion during the entry process and thus improving intake efficiency. Furthermore, it helps to create a more uniform airflow distribution within the inner barrel 2. When the exhaust gas is ejected from the inlet of the intake pipe 3 and impacts the barrel wall 21, it diffuses along the barrel wall 21, causing the exhaust gas to spiral upwards along the barrel wall 21 within the second cavity 20 (e.g., ...). Figure 3 (As shown by the dashed arrow). Furthermore, this air intake method can reduce the turbulence and impact of exhaust gas in the intake pipe 3, thereby reducing noise and vibration caused by unstable exhaust gas flow and improving the overall operational stability of the separation device 100.

[0061] It is understood that, in addition to the above embodiment where the inlet of the air inlet pipe 3 is arranged along the direction perpendicular to the axis of the inner barrel 2 and facing the barrel wall 21 of the inner barrel 2, the direction of the inlet of the air inlet pipe 3 facing the barrel wall 21 of the inner barrel 2 can also be arranged at a 45-degree angle with the barrel wall 21 of the inner barrel 2, or other arrangements that allow the exhaust gas to spiral upward along the barrel wall 21 when it enters the inner barrel 2 from the inlet of the air inlet pipe 3. This embodiment does not limit this.

[0062] In some embodiments, such as Figure 1 and Figure 2As shown, the outlet of the inner barrel 2 is upward-facing. The separation device 100 also includes a rotating component 4, which is located within the first cavity 10 and above the outlet of the inner barrel 2. The rotating component 4 is configured to direct the gas flowing out of the inner barrel 2 toward the side wall 11 of the outer barrel 1. In other words, a rotating component 4 is also provided above the inner barrel 2, enabling the gas flowing out of the inner barrel 2 to flow toward the side wall 11 of the outer barrel 1. Thus, by directing the exhaust gas from the inner barrel 2 toward the side wall 11 of the outer barrel 1 via the rotating component 4, combined with the centrifugal force of the exhaust gas spiraling upward along the barrel wall 21 of the inner barrel 2, the centrifugal force of the exhaust gas is increased, resulting in more thorough separation of solid dust particles and water mist in the exhaust gas, leading to a better separation effect.

[0063] Furthermore, the rotating assembly 4 includes a rotating member 41, which is rotatably connected to the first cavity 10 of the outer barrel 1 and located above the outlet of the inner barrel 2. The rotation axis of the rotating member 41 is parallel to the axis of the outer barrel 1, and the rotating member 41 can rotate under the push of the gas flowing out of the inner barrel 2. In this way, the rotating member 41 is located above the outlet of the inner barrel 2. When the exhaust gas flows out of the inner barrel 2, some solid dust particles and water mist have already been separated. During the continuous rise of the exhaust gas, the rotation of the rotating member 41 can force the exhaust gas from the rising state to the horizontal direction, so that the solid dust particles and water mist in the exhaust gas are separated onto the side wall 11 of the outer barrel 1 under the action of the rotating member 41. Moreover, under the action of the rotating member 41, an upward force can be provided for the separated exhaust gas, so that it can flow out smoothly from the separation device 100.

[0064] Optionally, such as Figure 2As shown, the rotating assembly 4 also includes a support member 42 and a guide member 43. The support member 42 is connected to the first cavity 10 and is positioned near the top cover 12 of the outer tub 1. One end of the guide member 43 is connected to the bottom of the inner tub 2, and the other end of the guide member 43 is connected to the support member 42. The guide member 43 extends along the axial direction of the outer tub 1. The rotating member 41 is rotatably mounted on the guide member 43 and can move along the guide member 43. That is, the rotating member 41 moves along the guide member 43 in an extension direction parallel to the axial direction of the outer tub 1. In this way, on the one hand, the guide member 43, as a guiding component for the rotating member 41, can share some of the stress and friction generated by the rotating member 41 during rotation. This helps to reduce direct contact and wear between the rotating member 41 and other components, thereby extending the service life of the entire rotating assembly 4. On the other hand, the rotating component 41 moves along the extension direction of the axis of the guide component 43 under the guidance of the guide component 43, so that the rotating component 41 can adjust the distance between the rotating component 41 and the inner barrel 2 according to the intensity of the exhaust gas flow in the inner barrel 2. When the exhaust gas flow in the inner barrel 2 is strong, the exhaust gas spirals upward along the barrel wall 21 of the inner barrel 2, and its centrifugal force is strong enough. When the exhaust gas flows out of the inner barrel 2, the solid dust particles and water mist in the exhaust gas are separated under the action of centrifugal force. However, the centrifugal force weakens during the upward process of the exhaust gas. Therefore, the rotating component 41 is set at a position where the centrifugal force of the exhaust gas is weaker, so as to further separate the solid dust particles and water mist in the exhaust gas. When the exhaust gas flow in the inner barrel 2 is weak, the centrifugal force is weak after the exhaust gas flows out of the inner barrel 2. At this time, the rotating component 41 is set at a position close to the inner barrel 2 to separate the solid dust particles and water mist in the exhaust gas flowing out of the inner barrel 2, ensuring the separation effect. Meanwhile, the movement of the rotating part 41 can more effectively control the flow direction and speed of the exhaust gas, improving the adaptability and operability of the separation device 100.

[0065] Further, see Figure 2The rotating assembly 4 also includes a limiting member 44, which is disposed on the guide member 43 and near the outlet of the inner tub 2. The limiting member 44 is located below the rotating member 41 and is used to prevent the rotating member 41 from moving downward along the guide member 43. That is to say, a limiting member 44 is provided on the guide member 43, which is near the outlet of the inner tub 2, preventing the rotating member 41 from moving downward, so that the movement of the rotating member 41 is restricted between the support member 42 and the limiting member 44. In this way, the limiting member 44 restricts the lowest position of the rotating member 41 on the guide member 43, preventing the rotating member 41 from being in close contact with the outlet of the inner barrel 2, which would prevent the exhaust gas from flowing out of the inner barrel 2 smoothly and thus completing the separation of solid dust particles and water mist. This ensures that a certain gap is maintained between the rotating member 41 and the outlet of the inner barrel 2, allowing the exhaust gas to spiral upward with the help of the barrel wall 21 of the inner barrel 2 to smoothly separate solid dust particles and water mist. Then, the rotating member 41 further separates the solid dust particles and water mist from the exhaust gas. In addition, the limiting member 44 also ensures the stability and safety of the rotating member 41, preventing the rotating member 41 from contacting the inner barrel 2 and causing unnecessary collisions and damage.

[0066] In some embodiments, the rotating component 41 includes an impeller. Using an impeller as the rotating component 41 forces the exhaust gas flow from an upward direction to a horizontal direction as it passes through the impeller. Furthermore, the exhaust gas rotates at high speed under the action of the impeller, increasing the centrifugal force on the exhaust gas and ensuring effective separation of solid dust particles and water mist. In addition, the pressure of the exhaust gas increases after passing through the impeller, allowing the separated exhaust gas to continue to be transported upwards.

[0067] It is worth noting that the rotating component 41 can also be a turbine or other vortex structure, or other structure that can force the exhaust gas flow from the upward direction to the horizontal direction. This embodiment does not specifically limit this.

[0068] Furthermore, the impeller is made of polyimide plastics, such as polyimide (PI), polyetherimide (PEI), and polyamideimide (PAI). Polyimide plastics possess excellent thermal stability, mechanical properties, and flame retardancy, and have a relatively low specific gravity. Thus, on the one hand, the rotating component 41 can adaptively rotate according to the strength of the exhaust gas flow from the inner tank 2, and move up and down along the guide 43 by the rising exhaust gas. This eliminates the need for a separate drive component to drive the rotation and movement of the rotating component 41, reducing the volume of the separation device 100 and saving costs. On the other hand, using polyimide plastic for the rotating component 41 avoids the risk of damage due to temperature increases within the first cavity 10 after long-term use, and its flame retardancy reduces the risk of fire, ensuring the safe operation of the separation device 100.

[0069] It should be noted that the material of the rotating part 41 is not limited to polyimide plastics, but can also be polyphenylene sulfide, polysulfone or other lightweight and flame-retardant engineering plastics, such as polyvinyl chloride, polypropylene, polyvinylidene fluoride. This embodiment does not limit this.

[0070] In some embodiments, such as Figure 1 and Figure 2 As shown, the separation device 100 also includes a rinsing assembly 5, which is configured to rinse the side wall 11 of the outer tank 1. That is, the rinsing assembly 5 can rinse the side wall 11 of the outer tank 1. In this way, by rinsing the side wall 11 of the outer tank 1 by the rinsing assembly 5, it is possible to avoid the accumulation of solid dust particles and water mist on the side wall 11 of the outer tank 1 after long-term use. This would prevent the solid dust particles and water mist from adhering to the side wall 11 of the outer tank 1 after separation from the exhaust gas, thus ensuring the separation of solid dust particles and water mist from the exhaust gas and affecting the separation effect of the separation device 100.

[0071] Furthermore, such as Figure 2 As shown, the rinsing assembly 5 includes an inlet pipe 51 and a rinsing pipe 52. The rinsing pipe 52 is located on the top cover 12 of the outer tub 1. The inlet pipe 51 is connected to the rinsing pipe 52, and the rinsing pipe 52 has several water outlets facing the side wall 11 of the outer tub 1. In other words, the inlet pipe 51 is connected to the rinsing pipe 52 to increase the water flow to the rinsing pipe 52. The multiple water outlets of the rinsing pipe 52 are facing the side wall 11 of the outer tub 1 to rinse the side wall 11. In this way, on the one hand, the water outlets facing the side wall 11 of the outer tub 1 allow the water flow to act directly on the side wall 11, reducing the dispersion and refraction of the water flow inside the outer tub 1, thereby improving the cleaning efficiency. On the other hand, rinsing the side wall 11 by the rinsing pipe 52 avoids the situation where the side wall 11 is covered with solid dust particles and water mist and cannot continue to adhere, ensuring the separation effect of the separation device 100 under long-term use.

[0072] It is worth noting that the shape of the flushing tube 52 can be annular or other shapes, and this embodiment does not limit it.

[0073] Taking the flushing pipe 52 as an example, several water outlets are located on the lower surface of the flushing pipe 52 and spaced apart along its circumference. In other words, the flushing pipe 52 being annular means that it is arranged around the edge of the top cover 12 of the outer tub 1. This ensures that, on the one hand, the water outlets of the annular flushing pipe 52, located on its lower surface and spaced apart along its circumference, are evenly distributed around the side wall 11 of the outer tub 1, thus guaranteeing that the water flow fully covers the side wall 11 and reducing blind spots. On the other hand, because the water outlets are spaced apart and distributed annularly, multiple water outlets simultaneously spray water, forming a dense flushing network, improving flushing speed and efficiency.

[0074] In some embodiments, such as Figure 2 As shown, the rinsing assembly 5 also includes a first solenoid valve 53, which is connected to the water inlet pipe 51 to control the opening and closing of the water inlet pipe 51. Thus, the first solenoid valve 53 can quickly respond to control signals, enabling the immediate opening or closing of the water inlet pipe 51, thereby precisely controlling the start and end of the rinsing process. By adjusting the control signal of the first solenoid valve 53, parameters such as rinsing time and rinsing flow rate can be flexibly adjusted to meet different rinsing needs. Furthermore, controlling the water inlet pipe 51 through the first solenoid valve 53 eliminates the need for manual opening or closing of the water inlet pipe 51, reducing waiting time and improving work efficiency.

[0075] In some embodiments, the bottom of the inner barrel 2 is provided with a drain hole (not shown in the figure), which is positioned facing the bottom 13 of the outer barrel 1. In this way, when the exhaust gas in the air inlet pipe 3 enters the second cavity 20 of the inner barrel 2, most of the water mist in the exhaust gas will remain in the second cavity 20 and accumulate at the bottom of the inner barrel 2. The accumulated water mist can be discharged into the bottom 13 of the outer barrel 1 through the drain hole at the bottom of the inner barrel 2, thus avoiding excessive water mist accumulation at the bottom of the inner barrel 2 and affecting the separation effect of the separation device 100.

[0076] In some embodiments, such as Figure 1 and Figure 2 As shown, a drain pipe 6 is connected to the bottom 13 of the outer barrel 1. A second solenoid valve 54 is installed on the drain pipe 6 to control its opening and closing. By controlling the opening and closing of the drain pipe 6 through the second solenoid valve 54, the second solenoid valve 54 can be linked with the first solenoid valve 53 through a set program, and discharge the accumulated solid dust particles and water mist at the bottom 13 of the barrel according to the actual working conditions, so as to ensure the separation effect of the separation device 100.

[0077] Furthermore, such as Figure 2As shown, the bottom 13 of the outer barrel 1 is shaped like an inverted cone. In this way, the solid dust particles and water mist separated from the exhaust gas fall onto the bottom 13 of the outer barrel 1 under the action of gravity on the side wall 11 of the outer barrel 1. The inverted cone shape of the bottom 13 can increase the storage capacity of solid dust particles and water mist, so as to realize the centralized emission of a large amount of solid dust particles and water mist at a low frequency.

[0078] Optionally, such as Figure 2 As shown, the exhaust pipe 7 is located on the top cover 12 of the outer barrel 1, and at least part of the exhaust pipe 7 extends into the first cavity 10. In this way, when the exhaust gas separated by the rotating member 41 rises to the top cover 12 of the outer barrel 1, the exhaust gas comes into full contact with the side wall 11 of the outer barrel 1, the top cover 12 and the side wall into which the exhaust pipe 7 extends into the first cavity 10, so that the solid dust particles and water mist in the exhaust gas are separated again, and thus the solid dust particles and water mist in the exhaust gas discharged from the exhaust pipe 7 have been separated in the separation device 100.

[0079] In some embodiments, the diameter of the inner barrel 2 is one-half to two-thirds of the diameter of the outer barrel 1. That is, for example, when the diameter of the outer barrel 1 is 500 mm, the diameter of the inner barrel 2 is between 250 mm and 330 mm; or, when the diameter of the outer barrel 1 is 1000 mm, the diameter of the inner barrel 2 is between 500 mm and 660 mm, meaning the ratio of the diameter of the inner barrel 2 to the diameter of the outer barrel 1 is between 1:2 and 2:3. This ensures that the diameters of the inner barrel 2 and the outer barrel 1 are such that, when the exhaust gas flows out of the inner barrel 2, the centrifugal force can separate the solid dust particles and water mist from the exhaust gas, thereby ensuring the separation effect of the separation device 100 on the solid dust particles and water mist in the exhaust gas.

[0080] Furthermore, the ratio of the diameter of the intake pipe 3 to the diameter of the inner barrel 2 is 1:3. For example, when the diameter of the inner barrel 2 is 330mm, the diameter of the intake pipe 3 is 110mm; or, when the diameter of the inner barrel 2 is 660mm, the diameter of the intake pipe 3 is 220mm. This ensures that the exhaust gas in the intake pipe 3 can spirally rise along the barrel wall 21 of the inner barrel 2, avoiding insufficient power for the exhaust gas to spirally rise along the barrel wall 21 of the inner barrel 2 due to an excessively large diameter of the intake pipe 3, and also avoiding a decrease in the amount of exhaust gas flowing through the inner barrel 2 due to an excessively small diameter of the intake pipe 3, which would slow down the separation efficiency of the exhaust gas. The 1:3 ratio of the diameter of the intake pipe 3 to the diameter of the inner barrel 2 effectively ensures the separation effect of the separation device 100.

[0081] It is worth noting that the diameters of the outer barrel 1, the inner barrel 2, and the air inlet pipe 3 can be proportionally enlarged or reduced while satisfying the above ratio. This embodiment does not limit this.

[0082] See Figure 4The second aspect of this application discloses an exhaust gas treatment system 300 for treating the exhaust gas output from production equipment 301. The exhaust gas treatment system 300 includes a separation device 100 and an exhaust pipe 302 as described in the foregoing embodiments. The inlet pipe 3 of the separation device 100 is connected to the production equipment 301, allowing the exhaust gas output from the production equipment 301 to enter the separation device 100 via the inlet pipe 3. The exhaust pipe 302 is connected downstream of the separation device 100 and to the outlet pipe 7 of the separation device 100. In this way, the separation device 100 separates solid dust particles and water mist from the exhaust gas output from the production equipment 301, and the separated exhaust gas, free of solid dust particles and water mist, is discharged into the exhaust pipe 302. This prevents the accumulation of solid dust particles and water mist in the exhaust gas in the exhaust pipe 302, which could lead to complete blockage of the exhaust pipe 302 after prolonged use, resulting in interruption of the supply and shutdown of the production equipment 301. This ensures the normal operation of the production equipment 301 and guarantees production efficiency.

[0083] It should be noted that, in addition to the aforementioned separation device 100 and exhaust pipe 302, the exhaust gas treatment system 300 also includes an intermediate treatment device 303, an exhaust fan 304, and an exhaust chimney 305. The intermediate treatment device 303 is connected downstream of the exhaust pipe to treat the exhaust gas separated from the separation device 100; the exhaust fan 304 is connected downstream of the intermediate treatment device 303; and the exhaust chimney 305 is connected to the exhaust fan 304. The exhaust fan 304 discharges the exhaust gas, which has been treated by the intermediate treatment device 303 and meets emission standards, through the exhaust chimney 305.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
