However, due to the presence of a large amount of sulfide components in the flue gas, acid condensation is easily generated in the pipeline, which is corrosive to both the pipeline and the flue gas heat exchanger. The above-mentioned equipment does not carry out targeted treatment on it, and the service life of the flue gas heat exchanger will be reduced after continuous use. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides an industrial waste gas waste heat recovery device, which solves the current problem that the flue gas is corrosive to the equipment due to the lack of filtering treatment.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: an industrial waste gas waste heat recovery device, comprising a heat exchange chamber, a flue gas heat exchanger, and an external connecting frame, wherein the flue gas heat exchanger is arranged inside the heat exchange chamber, and the external connecting frame is fixedly connected to the front end surface of the heat exchange chamber;

[0007] The inner end of the external connecting frame is further provided with a filter frame, the periphery of the external connecting frame is provided with a self-locking support frame, the side end of the self-locking support frame is provided with a connecting block, and the other side end surface of the self-locking support frame is provided with an inclined self-locking buckle;

[0008] The filter frame further comprises a filter element and an arcuate groove. The filter element is fixedly mounted on the inner end surface of the filter frame, and the arcuate groove is opened on the outer left and right end surfaces of the filter frame.

[0010] As an optimal technical solution of the present invention, the inclined self-locking buckle has a specific form of a columnar structure, and laterally penetrates the self-locking support frame and the external connecting frame, wherein the end facing the inside is an inclined structure and the other end is a disc structure.

[0011] As a preferred technical solution of the present invention, six groups of inclined self-locking buckles are provided and are symmetrically distributed on the left and right sides of the external connecting frame, and the inner inclined surface structure can be rotated to adjust the direction as needed.

[0015] Compared with the existing technology, the utility model provides an industrial waste gas waste heat recovery device with the following beneficial effects:

[0016] The industrial waste gas waste heat recovery equipment is provided with a filter frame, a self-locking support frame, a bevel self-locking buckle and an arc groove. When the equipment is used to recover the waste heat of industrial waste gas, the operator assembles the equipment at the front end of the waste heat recovery equipment, so that the waste gas discharge port is connected to the external connection frame. When the waste gas is subjected to waste heat recovery treatment, the waste gas first needs to be filtered through the filter element. The waste gas passing through the filter element enters the heat exchange chamber and is processed by the flue gas heat exchanger and cooperates with the external equipment to perform waste heat recovery treatment. When the filter element structure of the equipment needs to be replaced, the operator only needs to rotate the bevel self-locking buckle to the bevel facing Then insert both hands into the arc groove and pull out the filter frame. When the outer side of the filter frame contacts the inclined self-locking buckle, slowly push the inclined self-locking buckle outward through the inclined structure. The inclined self-locking buckle is subjected to pressure to apply pressure to the spring. After the spring is contracted, the inclined self-locking buckle continues to move toward the inside of the sleeve until the filter frame is taken out as a whole and the spring rebounds to reset the inclined self-locking buckle. Then the operator rotates the inclined self-locking buckle so that the inclined surface faces outward and slowly pushes in the new filter frame to repeat the above steps until the inclined self-locking buckle rebounds after the filter frame is installed.

[0017] Through the above steps, the device can achieve the following beneficial effects:

[0018] By placing the filter frame and filter element, the equipment can have the ability to pre-filter the exhaust gas. On this basis, by setting the self-locking support frame and the inclined self-locking buckle, the overall structure of the filter frame can be quickly replaced and installed. Therefore, the equipment can not only reduce the corrosion of the exhaust gas to the flue gas heat exchanger and the inner wall of the pipeline, but also make the filter structure have the effect of rapid replacement, which not only increases the service life of the equipment, but also reduces the time required to replace the filter structure.

The side end of the self-locking support frame 5 is provided with a connecting block 6, and the connecting block 6 fixes the self-locking support frame 5 and the external connecting frame 3. The other side end surface of the self-locking support frame 5 is provided with an inclined self-locking buckle 7, and the inclined self-locking buckle 7 fixes the filter frame 4;

[0027] The filter frame 4 further includes a filter element 401 and an arcuate groove 402 . The filter element 401 is fixedly mounted on the inner end surface of the filter frame 4 , and the arcuate groove 402 is opened on the outer left and right end surfaces of the filter frame 4 .

[0028] In this embodiment, the inclined self-locking buckle 7 further includes a sleeve 701 and a spring 702. One side of the spring 702 is fixedly connected to the outer end surface of the inclined self-locking buckle 7, and the inner bottom end of the sleeve 701 is fixedly connected to the other side of the spring 702. The inclined self-locking buckle 7 is a columnar structure and laterally penetrates the self-locking support frame 5 and the external connecting frame 3. One end facing inward is an inclined structure, and the other end is a disc structure.

[0029] Specifically, when the inner inclined surface structure of the inclined surface self-locking buckle 7 contacts the filter frame 4, it can be effectively lifted up, so that the inclined surface self-locking buckle 7 as a whole moves into the sleeve 701;

[0030] In this embodiment, six groups of inclined self-locking buckles 7 are provided, and are symmetrically distributed on the left and right sides of the external connecting frame 3. The inner inclined surface structure can be rotated to adjust the direction as needed; four groups of connecting blocks 6 are provided, and they pass through the self-locking support frame 5 from the upper and lower ends and are fixedly connected to the external connecting frame 3;

[0031] Specifically, by fixing the four sets of connecting blocks 6, the self-locking support frame 5 can be stably installed on the periphery of the external connecting frame 3;

[0032] In this embodiment, arc-shaped groove structures are provided on the inner sides of the left and right ends of the external connecting frame 3, and the positions correspond to the arc-shaped grooves 402; the external connecting frame 3 needs to be connected to the exhaust gas outlet so that the exhaust gas passes through the filter frame 4, and the heat exchange chamber 1 and the flue gas heat exchanger 2 need to be connected to the external waste heat recovery structure to construct a complete waste heat recovery path.

When the waste gas is subjected to waste heat recovery treatment, the waste gas first needs to be filtered through the filter element 401. The waste gas passing through the filter element 401 enters the interior of the heat exchange chamber 1 and is processed by the flue gas heat exchanger 2 and cooperates with the external equipment to perform waste heat recovery treatment. When the filter element 401 structure of the equipment needs to be replaced, the operator only needs to rotate the inclined self-locking buckle 7 so that the inclined surface faces inward, and then insert both hands into the interior of the arc groove 402. When the filter frame 4 is pulled out and the outer side of the filter frame 4 contacts the inclined self-locking buckle 7, the inclined self-locking buckle 7 is slowly pushed outward through the inclined structure. The inclined self-locking buckle 7 is subjected to pressure and applies pressure to the spring 702.
