[0032] Please see Figures 1 to 6 This application provides a waste gas recovery machine for a reactor, including: a support frame 1, a gas collection hood 2, and a purification treatment unit 3.

[0033] The gas collection hood 2 is mounted on the support frame 1. The gas collection hood 2 includes an upper support component 21, a lower support component 22, and a cover 23 sleeved on the outer periphery of the upper support component 21 and the lower support component 22. The cover 23 is made of elastic material. The support diameter of the lower support component 22 is adjustable and used to adjust the inner diameter of the gas collection port of the gas collection hood 2.

[0034] The purification unit 3 is connected to the gas collection hood 2 via a pipeline.

[0035] Support frame 1 provides structural support for the entire equipment.

[0036] The gas collection hood 2 is designed to collect the exhaust gas emitted from the reactor. Its elastic material body 23 and adjustable lower support assembly 22 allow it to adapt to different working conditions.

[0037] The purification unit 3 is responsible for treating the waste gas collected through the gas collection hood 2.

[0038] In this application, the flexible material cover 23 can adapt to reactors of different sizes and shapes, providing a wider range of applications and greater flexibility; moreover, the adjustable gas collection port inner diameter allows for optimization for reactors with different production capacities, ensuring high efficiency in waste gas collection.

[0039] In related technologies, the waste gas emitted by the reactor during chemical reactions usually contains a variety of harmful compounds. Some of these compounds can be transported through waste gas pipelines, but this takes up a lot of space, and once the waste gas pipelines are installed, it is not convenient to clean and maintain the interior. Therefore, the waste gas generated by the reactor is generally collected by a movable gas collection hood 2 and transported through pipelines to the purification treatment unit 3 for purification treatment.

[0040] In this embodiment, the concentration of waste gas generated by the reactor varies greatly. In order to ensure the collection effect of waste gas generated by the reactor, the gas collection port of the gas collection hood 2 is set to be adjustable. When the waste gas volume is large, the inner diameter of the gas collection port of the gas collection hood 2 can be enlarged to ensure sufficient collection of waste gas. When the waste gas volume is small, the inner diameter of the gas collection port of the gas collection hood 2 can be reduced to ensure the efficiency of waste gas delivery.

[0041] In some embodiments, the lower support assembly 22 includes: a central frame 221; four linear telescopic members 222 arranged radially along the central frame 221 and circumferentially along the central frame 221; a drive unit 223 disposed on the central frame 221 for driving the four linear telescopic members 222 to extend and retract synchronously; and four arc-shaped support plates 224 disposed at the ends of the four linear telescopic members 222, the four arc-shaped support plates 224 being connected to one end of the air collection port of the air collection hood 2.

[0042] In this application, a drive unit 223 drives four linear telescopic members 222 to move synchronously, and four arc-shaped support plates 224 move radially along the hood 23, thereby adjusting the inner diameter of the gas collection port of the gas collection hood 2. The linear telescopic members 222 allow for precise adjustment of the inner diameter of the gas collection port, which is necessary for chemical reactions of different scales to ensure effective collection of exhaust gases. The drive unit 223 ensures that all telescopic members move synchronously, guaranteeing the uniform expansion and contraction of the gas collection hood 2, which is crucial for maintaining the shape and function of the hood 23.

[0043] In some embodiments, the linear telescopic member 222 includes: a threaded tube 2221 rotatably mounted on a central frame 221, one end of which is provided with a first conical wheel 2222; and a threaded rod 2223, the end of which is inserted into the threaded tube 2221 and connected to the threaded tube 2221 by threads; wherein, the power output end of the drive unit 223 is provided with a second conical wheel 2231, which meshes with four first conical wheels 2222.

[0044] In this application, the drive unit 223 drives the second conical wheel 2231 to rotate, which in turn drives four first conical wheels 2222 to rotate synchronously. The four first conical wheels 2222 then drive four threaded tubes 2221 to rotate, thereby achieving synchronous drive of the four linear telescopic components 222 and ensuring the accuracy of the synchronous drive. The linear telescopic components 222 achieve telescopic movement through the design of the threaded tubes 2221 and threaded rods 2223. The first conical wheels 2222 mesh with the second conical wheels 2231 of the drive unit 223, achieving synchronous control. The threaded connection provides smooth and reliable telescopic movement, reducing vibration and noise during operation. The threaded connection design improves the durability and ease of maintenance of mechanical components, reducing long-term operating costs.

[0045] In some embodiments, an adjustment mechanism 4 is further provided between the upper support component 21 and the lower support component 22 for adjusting the axial length of the cover 23.

[0046] In this application, the adjustment mechanism 4 includes an adjustment motor 41, an adjustment solenoid 42, and a screw, used to adjust the axial length of the enclosure 23. It can adjust the height of the enclosure 23 to accommodate reactors of different heights, increasing the applicability of the equipment. The electric adjustment mechanism 4 simplifies the operation process and improves work efficiency and safety.

[0047] In some embodiments, the adjustment mechanism 4 includes: an adjustment motor 41 disposed on the lower support assembly 22; an adjustment screw tube 42, one end of which is connected to the power output end of the adjustment motor 41; and an adjustment screw 43, one end of which is connected to the upper support assembly 21, and the other end is inserted into the adjustment screw tube 42 and connected to the adjustment screw tube 42 by a thread.

[0048] In some embodiments, the device further includes four inner support components 5 that support the inner surface of the cover 23. The inner support components 5 include: a slide rail 51, the top end of which is fixedly connected to the upper support component 21 and abuts against the inner surface of the cover 23; a slider 52, which is slidably disposed on the slide rail 51; and a support rod 53, one end of which is hinged to the arc-shaped support plate 224 and the other end of which is hinged to the slider 52.

[0049] In this application, the internal support assembly 5 includes a slide rail 51, a slider 52, and a support rod 53, which work together to stabilize and support the interior of the cover 23.

[0050] The design of the slide rail 51 and slider 52 allows the support rod 53 to move freely as the cover 23 extends and retracts, while the support rod 53 is hinged to the arc-shaped support plate 224, providing additional support. This design improves the overall stability of the cover 23, especially during extension and retraction, preventing deformation or damage to the cover 23. The interaction between the support rod 53 and the slide rail 51 ensures that the internal support can adapt to different configurations when the size of the cover 23 is adjusted, increasing the applicability and durability of the equipment.

[0051] Furthermore, a groove 511 is provided on the side of the slide rail 51 away from the cover 23, and the slider 52 is slidably disposed in the groove 511. The width of the support rod 53 is equal to the width of the groove 511.

[0052] In this application, the slide rail 51 is fixedly connected to the upper support assembly 21, the slider 52 slides in the slide groove 511, and the width of the support rod 53 is equal to the width of the slide groove 511, so that the maximum angle of the support rod 53 is parallel to the slide rail 51. The support rod 53 can also be set at an angle to the slide rail 51, thereby further improving the adjustment range of the gas collection hood 2.

[0053] Specifically, the upper part of the cover 23, that is, the part that contacts the slide rail 51, does not change, while the part of the support rod 53 that supports the cover 23 can not only extend and retract, but also adjust its angle, thereby expanding the range of adjustment of the cover 23.

[0054] In some embodiments, a sealing shell 24 is provided on the top of the upper support assembly 21, the sealing shell 24 is in communication with the pipeline, and the upper support assembly 21 is detachably connected to the sealing shell.

[0055] In this application, the sealing housing 24 is disposed on top of the upper support assembly 21 and communicates with the pipeline, providing a closed system to ensure that exhaust gas does not leak out. The sealing housing 24 ensures that exhaust gas will not leak into the environment during treatment, reducing pollution. The removable design of the sealing housing 24 simplifies maintenance and cleaning, reduces downtime, and is easy to maintain.

[0056] In some embodiments, a guide plate 231 is provided on the inner surface of the cover 23. The guide plate 231 is arranged axially along the inner surface of the cover 23, and a guide gap is formed between adjacent guide plates 231.

[0057] In some embodiments, the width of the guide vane 231 along the radial direction of the cover 23 gradually increases from bottom to top.

[0058] The guide plate 231 is disposed on the inner surface of the cover 23 and arranged along the axial direction to form a guide gap 232, which is used to guide and optimize the flow path of the exhaust gas.

[0059] The design of the deflector 231 makes its width gradually increase from bottom to top in order to adjust the airflow direction.

[0060] Optimized exhaust gas flow: The guide plate 231 improves the collection efficiency of exhaust gas by forming a specific airflow path, ensuring that the exhaust gas enters the purification unit 3 evenly.

[0061] Enhanced treatment effect: The gradually widening design helps to distribute airflow at different heights, further improving the uniformity and efficiency of exhaust gas treatment.

[0062] Specifically, the deflector plate 231 and the cover 23 are integrally formed.

[0063] The exhaust gas from this reactor can be accommodated by a cover 23 made of a mechanically elastic material, which can adapt to reactors of different sizes and shapes, providing a wider range of applications and greater flexibility. Moreover, by adjusting the diameter of the lower support assembly 22, the inner diameter of the gas collection port can be adjusted, allowing for optimization for reactors with different production capacities, ensuring high efficiency in exhaust gas collection.
