The energy input to the boiler includes chemical energy and electrical energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The boiler generates a certain amount of heat when in use, and the generated heat needs to be recovered. The heat is usually recovered through a recovery pipe, and the existing pipe is a device for boiler heat recovery. The recovery pipe is easy to scrape and clean the inside when in use, and the cleaning is convenient, which is convenient for the heat recovery and heating use of the recovery pipe body, and improves the convenience of cleaning the recovery pipe body in the boiler heat recovery and the heat recovery effect;

The recovery pipeline body 100 is also provided with:

[0026] A dust scraping mechanism is provided, and the dust scraping mechanism includes a dust scraping assembly arranged at the bottom end of the main pipe 101, sliding assemblies are arranged on both sides of the inside of the main pipe 101, the ends of the sliding assemblies and the ends of the dust scraping assemblies are fixed by screws, and the ends of the sliding assemblies are located on the inner side of the main pipe 101 and are provided with a pulling adjustment assembly. When the recovery pipe body 100 is recovering heat from the boiler and dirt is attached to the inside of the main pipe 101, the dust scraping mechanism can scrape the inside of the main pipe 101 to facilitate the heat recovery and heating use of the recovery pipe body 100, and improve the convenience of cleaning the recovery pipe body 100 in the boiler heat recovery and the heat recovery effect.

[0027] In order to facilitate the dust scraping treatment on the inner surface of the main pipe 101 through the dust scraping assembly and effectively recover heat, in the present embodiment, preferably, the dust scraping assembly includes a pull ring 1011 arranged at the bottom end of the inside of the main pipe 101, and the outer surface of the pull ring 1011 is fixed with a dust scraping annular plate 1012 by screws, and the outer surface of the dust scraping annular plate 1012 is in contact with the inner surface of the main pipe 101. The pull ring 1011 drives the dust scraping annular plate 1012 to slide inside the main pipe 101 to scrape and clean the dust, thereby facilitating the cleaning process.

[0028] In order to facilitate the stable sliding dust scraping process of the pull ring 1011 and the dust scraping ring plate 1012 through the sliding component and make cleaning more convenient, in the present embodiment, preferably, the sliding component includes a pulling groove 1015 opened on both sides of the inside of the main pipe 101, and a moving block 1013 is arranged at the inner bottom end of the pulling groove 1015. The end of the moving block 1013 is fixed to the upper surface of the pull ring 1011 by screws. The moving block 1013 is slid inside the pulling groove 1015 to drive the pull ring 1011 and the dust scraping ring 1012 to move and adjust, so as to facilitate the sliding dust scraping process.

[0029] In order to facilitate the movement of the movable block 1013 and the pull ring 1011 by pulling the adjustment component, and to facilitate pulling adjustment, in the present embodiment, preferably, the pulling adjustment component includes a pull rod 1014 fixed to the top of the movable block 1013 by screws, and the end of the pull rod 1014 is located at the top surface of the main pipe 101 and is provided with a pull head 1016. The pull head 1016 is held to pull the pull rod 1014, and the pull rod 1014 drives the movable block 1013 and the pull ring 1011 to move when being pulled, so as to facilitate pulling adjustment.

[0030] A buffer protection mechanism is provided, and the buffer protection mechanism includes a heat recovery component arranged on the outer surface of the main pipeline 101. The surface of the heat recovery component is provided with a buffer protection component, so that when the recovery pipeline body 100 is recovering heat, the outer surface of the outer casing 103 can be protected by the buffer protection mechanism, which is not easy to cause deformation and damage, thereby improving the buffer protection effect of the recovery pipeline body 100 when it is used for boiler heat recovery.

[0031] In order to facilitate heating of the recovery pipe body 100 when recovering heat through the heat recovery component, in the present embodiment, preferably, the heat recovery component includes an outer casing 103 arranged on the outer surface of the main pipe 101, and both ends of the outer casing 103 are integrally formed with fixing rings 1031, and the fixing ring 1031 and the surface of the flange 102 are fixed by screws. The outer casing 103 is fixedly installed on the outer surface of the main pipe 101 by the fixing ring 1031 for use, which is convenient for installation operation. The inner surface of the outer casing 103 and the outer surface of the main pipe 101 form a heat recovery chamber 1034, and the heat recovery chamber 1034 is formed after the outer casing 103 is fixedly installed, and water is added to the inside of the heat recovery chamber 1034, so that the recovery pipe body 100 is convenient for heating when recovering heat.

[0032] In order to facilitate the buffering and protection of the outer surface of the outer casing 103 through the buffering and protection component, and to prevent it from being deformed and damaged when impacted, in the present embodiment, preferably, the buffering and protection component includes a limiting buffer groove 1033 opened on both sides of the outer casing 103, the internal limiting position of the limiting buffer groove 1033 is a limiting arc buffer plate 1032, and the lower surface of the limiting arc buffer plate 1032 and the inner bottom end of the limiting buffer groove 1033 are connected by screws with an elastic plate 1035 fixed thereto. When the surface of the outer casing 103 is impacted, it directly impacts the surface of the limiting arc buffer plate 1032, and the elastic plate 1035 is deformed to buffer and protect the limiting arc buffer plate 1032, thereby reducing the impact.

[0033] Working principle and use process of the utility model: when using the pipeline structure of the boiler heat recovery pipeline, firstly, the flange 102 contacts the end of the boiler heat discharge pipeline, and the bolts penetrate the inside of the flange 102 to fix it, so that the recovery pipeline body 100 is fixedly installed through the flange 102 and then the heat is recovered and used;

[0034] After the recovery pipe body 100 is fixedly installed, the outer casing 103 is closed on the outer surface of the main pipe 101 again, and the fixing ring 1031 is fixed by screws so that the outer casing 103 is fixed on the outer surface of the main pipe 101. At this time, cold water can be injected into the interior through the top of one side of the outer casing 103, so as to heat the internal cold water after the heat of the recovery pipe body 100 is recovered. When the heat is recovered and exposed to the outside for installation and use, when the outer surface of the outer casing 103 is hit by an external object, it directly hits the surface of the limiting arc buffer plate 1032 to exert force on the elastic plate 1035. The elastic plate 1035 is deformed by the force to buffer the limiting arc buffer plate 1032 inside the limiting buffer groove 1033, so that the limiting arc buffer plate 1032 buffers the rebound of the impacted object, which is convenient for reducing the impact, buffering protection, and not easy to cause deformation and damage, thereby improving the buffering and protection effect of the recovery pipe body 100 when the boiler heat is recovered;

[0035] Finally, when the recovery pipe body 100 is used for long-term waste heat recovery and too much dust accumulates inside the main pipe 101, the two pull heads 1016 can be held at the same time to pull the two pull rods 1014. The movement of the pull rod 1014 drives the moving block 1013 to slide inside the pulling groove 1015, and the sliding of the two moving blocks 1013 drives the pull ring 1011 and the dust scraping annular plate 1012 to slide inside the main pipe 101. The dust scraping annular plate 1012 slides inside the main pipe 101 to scrape the dust, and the cleaning of the inside of the main pipe 101 is more convenient, which is convenient for the recovery pipe body 100 to recover heat for heating, and improves the convenience of the recovery pipe body 100 in the cleaning of boiler heat recovery and the heat recovery effect.
