[0038] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0039] Example, see Figure 1~Figure 2 , which is an embodiment of the present utility model, proposes an industrial furnace waste gas treatment device, including an adsorption cylinder 1, a lower support plate 2, an upper limit plate 3, a rotating shaft 4, and a flipping plate 5. The lower support plate 2 is arranged at the lower end of the adsorption cylinder 1, and the lower support plate 2 has an air inlet; the upper limit plate 3 is arranged at the upper end of the adsorption cylinder 1, and the upper limit plate 3 has an air outlet. The cavity surrounded by the adsorption cylinder 1, the lower support plate 2 and the upper limit plate 3 is an adsorption cavity for filling the adsorbent; the rotating shaft 4 is rotatably connected to the adsorption cylinder 1, and at least one end of the rotating shaft 4 is located outside the adsorption cylinder 1; the flipping plate 5 is arranged on the rotating shaft 4, and the number of the flipping plates 5 is at least two, and all the flipping plates 5 are arranged along the circumferential direction of the rotating shaft 4.

[0040] In this embodiment, the axis of the rotating shaft 4 is horizontally arranged in the front-to-back direction, and four flip plates 5 are evenly arranged around the rotating shaft 4. Exhaust gas enters the adsorption chamber within the adsorption cylinder 1 through the air inlet on the lower support plate 2. After being adsorbed by the adsorbent in the adsorption chamber, it is discharged through the air outlet on the upper limit plate 3. The adsorbent can adsorb harmful substances in the exhaust gas. When the rotating shaft 4 rotates, the flip plates 5 rotate accordingly, flipping the adsorbent in the adsorption chamber. By flipping the adsorbent, sufficient contact between the adsorbent and the exhaust gas is ensured, avoiding local adsorption saturation of the adsorbent particles that affects the overall adsorption effect, thereby improving adsorption efficiency and uniformity.

[0041] Furthermore, if Figure 2 As shown, the tipping plate 5 has a drop opening 6 at one end close to the rotating shaft 4. The adsorbent flipped up by the tipping plate 5 can fall through the drop opening 6, which can ensure the fluidity of the adsorbent particles during the flipping process.

[0042] Furthermore, if Figure 3 As shown, both sides of the flipping plate 5 near one end of the rotating shaft 4 have arc-shaped positioning plates 7. The inner wall of the positioning plate 7 contacts the side wall of the rotating shaft 4. The positioning plate 7 has a through hole, and the side wall of the rotating shaft 4 has a screw hole. It also includes a locking bolt 8. After one end of the locking bolt 8 passes through the through hole on the positioning plate 7, it is threadedly connected with the screw hole on the rotating shaft 4, and the end faces of two adjacent positioning plates 7 are in contact. The positioning plate 7 is locked to the outer periphery of the rotating shaft 4 using the locking bolt 8, and the flipping plate 5 can be locked to the rotating shaft 4. The structure is simple, the connection is firm and reliable, and the disassembly and assembly are convenient and quick, saving time and effort. All the positioning plates 7 are spliced ​​together to form a ring, and the adjacent positioning plates 7 can play a supporting and limiting role, which is more stable.

[0043] Furthermore, if Figure 1 and Figure 2 As shown, the adsorption device further includes a feed valve 9 and a discharge valve 10. The feed valve 9 is provided on the adsorption cylinder 1 and is located outside the upper end of the adsorption cylinder 1. The outlet of the feed valve 9 is communicated with the interior of the adsorption cylinder 1. The discharge valve 10 is provided on the adsorption cylinder 1 and is located outside the lower end of the adsorption cylinder 1. The inlet of the discharge valve 10 is communicated with the interior of the adsorption cylinder 1. The feed valve 9 is used to add adsorbent particles to the adsorption cylinder 1, and the discharge valve 10 is used to discharge adsorbent particles that have been saturated in the adsorption cylinder 1, making it easier to replace the adsorbent particles and ensuring that the device always maintains good adsorption performance.

[0044] Furthermore, if Figure 2As shown, the device further includes a support base 11 and a rotary drive mechanism 12. The support base 11 is disposed outside the adsorption cylinder 1; the rotary drive mechanism 12 is disposed on the support base 11 and is in driving connection with the rotating shaft 4. The support base 11 provides mounting support for the rotary drive mechanism 12, ensuring its installation stability and normal operation. The rotary drive mechanism 12 provides rotational power to the rotating shaft 4, enabling the flipping plate 5 to flip the adsorbent particles, thereby achieving an automatic flipping function, which can improve the operating efficiency and automation level of the device.

[0045] Furthermore, if Figure 1 As shown, it also includes a pretreatment barrel 13, a liquid inlet valve 14, an air inlet valve 15, and a liquid drain valve 16. The pretreatment barrel 13 has a treatment liquid inlet 17, a treatment liquid outlet 18 and a waste gas inlet 19. The waste gas inlet 19 is located below the liquid level of the treatment liquid in the pretreatment barrel 13. The lower support plate 2 is arranged at the upper end of the pretreatment barrel 13; the liquid inlet valve 14 is arranged at the treatment liquid inlet 17; the air inlet valve 15 is arranged at the waste gas inlet 19; and the liquid drain valve 16 is arranged at the treatment liquid outlet 18.

[0046] The pretreatment barrel 13 is provided with supporting legs at the bottom. The lowest point of the treatment liquid outlet 18 is located above the lowest point of the supporting legs. The pretreatment barrel 13 provides support for the adsorption cylinder 1. The exhaust gas inlet 19 is located below the liquid level of the treatment liquid, so that the exhaust gas passes through the treatment liquid for preliminary treatment, removing some harmful substances and reducing the pressure of subsequent adsorption treatment. The liquid inlet valve 14 is used to control the inflow of treatment liquid, the air inlet valve 15 is used to control the entry of exhaust gas, and the liquid discharge valve 16 is used to discharge the treated waste liquid. By adjusting the switching status of the liquid inlet valve 14, the air inlet valve 15, and the exhaust valve 16, it is convenient to control the inflow and outflow of treatment liquid and exhaust gas, as well as the discharge of waste liquid, to ensure the smooth progress of the pretreatment process.

[0047] Furthermore, if Figure 1 As shown, the lower end of the pretreatment barrel 13 is a conical structure, and the treatment liquid outlet 18 is located at the bottom of the pretreatment barrel 13. It is convenient to discharge the waste liquid in the pretreatment barrel 13 cleanly.

[0048] Furthermore, if Figure 1 As shown, the system further includes a filter 20, which is positioned at the inlet of the air inlet valve 15. Exhaust gas is filtered through the filter 20 before entering the pretreatment barrel 13, removing large impurities and ensuring a purer exhaust gas entering the pretreatment barrel 13 and the adsorption cylinder 1. This reduces the burden on the treatment fluid and adsorbent, improving the treatment efficiency of the treatment fluid and the adsorption efficiency of the adsorbent, extending the treatment time of the treatment fluid and the service life of the adsorbent. The filter 20 can be cleaned or replaced regularly to ensure long-term use.

[0049] Furthermore, if Figure 1As shown, the system also includes a demister 21, which is disposed within the pretreatment barrel 13 and above the treatment liquid inlet 17. The demister 21 removes tiny droplets and mist from the exhaust gas, ensuring that the exhaust gas entering the adsorption cylinder 1 is purer, reducing the burden on the adsorbent, improving the adsorption effect, and extending the adsorbent's service life. The demister 21 can be cleaned or replaced regularly to ensure long-term use.

[0050] Furthermore, if Figure 1 As shown, the device further includes a guide hood 22 and an exhaust fan 23. The guide hood 22 is arranged above the upper limit plate 3; the exhaust fan 23 is arranged on the top of the guide hood 22. The guide hood 22 is used to guide the flow direction of the treated gas. The exhaust fan 23 generates suction by rotating, which can accelerate the gas exhaust speed and improve the processing efficiency of the device.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
