The industrial waste gas contains a large amount of impurities and particulate matters, which are easily adhered to the inner wall of the pipeline during the heat exchange process. Over time, the inner wall of the heat exchange pipeline is likely to become thick, resulting in a reduction in the heat exchange efficiency of the heat exchange pipeline. Moreover, the cleaning of the inner wall of the heat exchange pipeline is rather troublesome. The regular cleaning work of the heat exchange pipeline increases the labor intensity of workers and is not conducive to popularization and use. Content of the Utility Model

Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] The present utility model provides a heat exchange device as Figures 1-4 shown, including a heat exchange box 1. A heat exchange pipeline 2 is arranged inside the heat exchange box 1. The cross-section of the heat exchange pipeline 2 is serpentine. A water inlet pipe and a water outlet pipe are fixedly connected to the outer wall of the heat exchange box 1. Valves are arranged on both the water inlet pipe and the water outlet pipe. The serpentine heat exchange pipeline 2 can greatly enhance the retention of gas inside the heat exchange box 1, enabling the heat in the waste gas to be well transferred to the water inside the heat exchange box 1. And the water heated by the waste heat can be used through the water outlet pipe by opening the valve.

[0033] Furthermore, an air inlet box 3 is fixedly connected to one side of the heat exchange box 1. A filtering mechanism 4 is arranged inside the air inlet box 3. The filtering mechanism 4 includes: a filter screen 41, fixing plates 42, a cleaning assembly 43, a pull rod 44 and a sealing assembly 45. The filter screen 41 is fixedly installed inside the air inlet box 3. The filter screen 41 can intercept impurities and particles in the industrial waste gas, so as to prevent these impurities and particles from entering the inside of the heat exchange pipe 2 and adhering to the inner wall of the heat exchange pipe 2, thereby affecting the heat exchange efficiency of the heat exchange pipe 2; a plurality of fixing plates 42 are respectively arranged on both sides of the filter screen 41, and the plurality of fixing plates 42 are symmetrically arranged with the filter screen 41 as the center; the cleaning assembly 43 is arranged inside the fixing plate 42; both ends of the pull rod 44 are fixedly connected to the plurality of fixing plates 42, and both ends of the pull rod 44 are slidably inserted and connected to the top end of the air inlet box 3. The cross section of the pull rod 44 is in a C shape, and the length of the pull rod 44 is just enough to drive the fixing plate 42 to move from the bottom end to the top end of the filter screen 41. The pull rod 44 can be used to pull the fixing plate 42, so that the cleaning assembly 43 can clean both sides of the filter screen 41 at the same time, which is convenient for use; the sealing assembly 45 is arranged at the top and bottom ends of the air inlet box 3.

[0034] Specifically, the cleaning assembly 43 includes: a synchronous plate 431, connecting rods 432, cleaning plates 433 and compression springs 434. The synchronous plate 431 is slidably inserted and connected to the inner cavity of the fixing plate 42; one ends of a plurality of connecting rods 432 are fixedly connected to the synchronous plate 431; the other ends of the plurality of connecting rods 432 are fixedly connected to the cleaning plates 433. The plurality of cleaning plates 433 are symmetrically arranged with the filter screen 41 as the center. A brush is arranged on one side of the cleaning plate 433 close to the filter screen 41 for cleaning the filter screen 41; a plurality of compression springs 434 are all located inside the fixing plate 42. One ends of the plurality of compression springs 434 are fixedly connected to the synchronous plate 431, and the other ends of the plurality of compression springs 434 are fixedly connected to the inner wall of the fixing plate 42. The compression springs 434 are always in a compressed state, so as to provide a stable elastic force for the cleaning plates 433 on the plurality of connecting rods 432 through the synchronous plate 431, so that the cleaning plates 433 can tightly fit on the outer wall of the filter screen 41 and can clean the gaps on the outer wall of the filter screen 41, which is convenient for use.

[0035] Specifically, the sealing assembly 45 includes a sealing ring 451 and a sealing cover 452. A plurality of sealing rings 451 are respectively fixedly connected to the top and bottom of the air inlet box 3. A cleaning groove communicated with one of the sealing rings 451 is formed at the bottom of the air inlet box 3. An external thread is provided on the outer wall of the sealing ring 451. The sealing cover 452 is threadedly inserted with the sealing ring 451. The sealing ring 451 and the sealing cover 452 can seal the air inlet box 3. A handle 5 is arranged inside another sealing ring 451. The handle 5 is fixedly connected to the top of the pull rod 44. When it is necessary to clean the filter net 41, the sealing covers located at the top and bottom of the air inlet box 3 can be opened. Thus, the pull rod 44 can be pulled through the handle, and the fixing plate 42 can drive the cleaning plate 433 to clean the outer walls on both sides of the filter net 41 at the same time. Moreover, the dust cleaned off can directly fall out through the cleaning groove at the bottom of the air inlet box 3. After the cleaning is completed, the sealing cover 452 can be closed with the sealing ring 451 again. And when the sealing ring 451 and the sealing cover 452 are connected, the handle 5 and the pull rod 44 can be limited to prevent the entire cleaning assembly 33 from shaking inside, which is convenient for use.

[0036] Further, a sealing plate 6 for supporting the filter net 41 is fixedly connected to the bottom end of the inner wall of the air inlet box 3. The cross section of the sealing plate 6 is T-shaped, and the shorter end can extend into the sealing ring 451 to ensure that there is no gas leakage, so as to ensure that industrial waste gas will not flow into the inside of the heat exchange box 1 without passing through the filtration of the filter net 41.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
