All of these components are integrated into the exhaust pipe. If one of these systems fails, the equipment needs to be shut down, and the damaged component needs to be removed and replaced before the equipment can be used normally. This is inefficient, time-consuming, and greatly increases the cost of equipment production. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] refer to Figure 1-3 As shown, the present invention provides a modular exhaust gas treatment device for a polyimide film production line, comprising: a spray tower 1, an exhaust gas treatment component, and an axial flow fan 3 connected in series via an exhaust pipe 2. The exhaust gas treatment component includes a rectangular shell 4, a rectangular mounting frame 6, and two exhaust gas treatment modules 14 connected in series on the exhaust pipe 2. The rectangular mounting frame 6 is movably installed through the rectangular shell 4, and the two exhaust gas treatment modules 14 are respectively installed through the rectangular mounting frame 6 along the gas flow direction. When the rectangular mounting frame 6 moves, the two exhaust gas treatment modules 14 move into the interior of the rectangular shell 4 respectively.

[0023] Combination Figure 1 and Figure 3 As shown, the rectangular housing 4 also has openings 5 ​​through both sides for the rectangular mounting bracket 6 to pass through. The openings 5 ​​are provided with two hollow connectors 9 that are respectively connected to the exhaust pipe 2 on the same side. When the two hollow connectors 9 are respectively connected to the two ends of one of the exhaust gas treatment modules 14, the exhaust gas treatment module 14 is connected in series in the exhaust pipe 2.

[0024] As described above, when using the exhaust pipe 2, spray tower 1, waste gas treatment component and axial flow fan 3 provided by this utility model, the axial flow fan 3 is started, and the waste gas enters the spray tower 1 and waste gas treatment component sequentially through the exhaust pipe 2. During this process, the waste gas is treated by a waste gas treatment module 14 on the rectangular mounting frame 6. When this waste gas treatment module 14 is damaged, it is pushed on one side of the rectangular mounting frame 6 to allow the spare waste gas treatment module 14 to enter the rectangular housing 4. At this time, the waste gas treatment module 14 in the rectangular housing 4 is pushed out. The waste gas treatment module 14 in the rectangular housing 4 is connected in series in the exhaust pipe 2 through two hollow connectors 9. At this time, the waste gas treatment module 14 outside the rectangular housing 4 can be replaced and repaired, allowing the waste gas treatment module 14 to be replaced after the equipment is shut down or after a short shutdown.

[0025] Furthermore, to facilitate the docking of the hollow connector 9 with the exhaust gas treatment module 14, refer to... Figure 3As shown, each of the two hollow connectors 9 has a telescopic pipe 8 connected to the exhaust pipe 2 at one of its opposite ends. The telescopic pipe 8 allows the hollow connector 9 to approach the exhaust gas treatment module 14, thus facilitating the docking of the hollow connector 9 with the exhaust gas treatment module 14. During this process, the telescopic pipe 8 prevents the exhaust pipe 2 from detaching from the hollow connector 9.

[0026] Furthermore, in order to improve the stability of the connection between the hollow connector 9 and the exhaust gas treatment module 14, refer to Figure 3 As shown, a spring 7 is fitted around the telescopic tube 8, abutting against the rectangular housing 4 and the hollow connector 9. The spring 7 is used to elastically press the hollow connector 9 against the exhaust gas treatment module 14. When the exhaust gas treatment module 14 is inside the rectangular housing 4, the hollow connector 9 automatically and elastically abuts against the exhaust gas treatment module 14 by the elastic force of the spring 7, which can prevent leakage at the gap between the hollow connector 9 and the exhaust gas treatment module 14.

[0027] In this utility model, combined with Figure 3-4 As shown, the rectangular mounting bracket 6 of this embodiment is also provided with two through holes 15, and two exhaust gas treatment modules 14 are respectively installed in the two through holes 15, and two hollow connectors 9 respectively abut against the two ends of the through holes 15 at the coaxial center.

[0028] Combination Figure 3-5 As shown, each exhaust gas treatment module 14 has an external mounting flange 11 for installation at one end. The external part of the through hole 15 has a mounting groove 10 to accommodate the mounting flange 11. The mounting groove 10 has multiple threaded holes 13 arranged in a ring array. Each threaded hole 13 has a fixing bolt 12 for connecting the mounting flange 11 and the rectangular mounting bracket 6.

[0029] As described above, by using the through hole 15 provided by this utility model, the exhaust gas treatment module 14 can be easily installed through the rectangular mounting bracket 6. In this process, the exhaust gas treatment module 14 is detachably installed in the through hole 15 through the mounting groove 10, multiple threaded holes 13, fixing bolts 12 and mounting flange 11, which facilitates the disassembly and replacement of the exhaust gas treatment module 14 on the rectangular mounting bracket 6 in the future.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
