[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0018] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, the utility model discloses a kind of waste gas collection mechanism with waste heat recovery function in cigarette factory in the drawing, including first pipeline 1, filter screen structure 3 and second pipeline 4, first pipeline 1 and second pipeline 4 are horizontally arranged, and filter screen structure 3 is installed between first pipeline 1 and second pipeline 4 by mounting structure 2, filter screen structure 3 includes outer frame 301 and inner frame 302, two inner frames 302 are arranged between two outer frames 301, outer frame 301 is laminated with inner frame 302, and one corner of outer frame 301 and inner frame 302 is rotatably connected by pivot 303, and filter screen 304 is fixedly installed in the inside of outer frame 301 and inner frame 302.

[0019] By connecting first pipeline 1 with the inlet of waste heat recovery equipment, and connecting second pipeline 4 with the exhaust outlet of cigarette factory, waste gas is filtered by filter screen structure 3 first, and then waste heat is recovered;By laminating multiple filter screens 304, dust particles in flue gas can be effectively blocked;In addition, by mounting structure 2, filter screen structure 3 can be disassembled as a whole and rotated around pivot 303, outer frame 301 and inner frame 302 are rotated and unfolded in turn, so that filter screen 304 is completely unfolded, and backwashing of filter screen 304 is facilitated;This design avoids the cumbersome installation of traditional multiple filter screens 304, makes installation more convenient, and multiple filter screens 304 improve filtering effect;Unfolding type backwashing operation is more simple and convenient, ensuring the recycling of filter screen 304, thereby reducing cost output.

[0020] Please refer to Figure 1 and Figure 3 , first pipeline 1 and second pipeline 4 have the same square caliber, and the surface area of filter screen 304 is equal to the internal space of first pipeline 1, so that flue gas in second pipeline 4 passes through filter screen 304 normally and then enters first pipeline 1.

[0021] Please refer to Figure 1 , Figure 3 and Figure 4 , first pipeline 1 and second pipeline 4 are fixedly connected with mounting structure 2 on the outer side, mounting structure 2 on the same side of first pipeline 1 and second pipeline 4 is diagonally distributed, mounting structure 2 includes buckle rod 202 and clamping plate 204, two clamping plates 204 are fixedly connected to the outer side of first pipeline 1 and second pipeline 4, buckle rod 202 is rotatably connected between two clamping plates 204 through pin shaft 203 at one end, and the other end is fixedly connected with elastic clamping block 205, and outer side wall of outer frame 301 is provided with matching clamping groove 305.

[0022] It is worth noting that the filter screen structure 3 is disassembled, and the elastic clamping block 205 is moved out from the inside of the clamping groove 305 by rotating the buckle rod 202 manually.
