[0034] like Figure 1-Figure 7 As shown, the principle of the heat dissipation recovery device for waste heat pipes of gas power generation provided in this embodiment is as follows: when using the device, the box door 26 should be opened first, and then the bolts 19 on the waste heat recovery structure 2 should be removed, and then the sealing chamber door 18 on the waste heat recovery structure 2 should be opened, and then the outer hexagonal nut 10 should be screwed on the first sealing spiral ring opening 8 or the second sealing spiral ring opening 9 on each fin 6 to be installed, and after preparation, the fins 6 should be installed in the fin protection box 5 in sequence according to the rule that the first sealing spiral ring opening 8 corresponds to the second sealing spiral ring opening 9, and then the high temperature resistant sealing gasket ring 102 should be placed in the first The sealing spiral ring opening 8 and the second sealing spiral ring opening 9 are connected, and then the outer hexagonal nut 10 is screwed between the first sealing spiral ring opening 8 and the second sealing spiral ring opening 9 so that the first sealing spiral ring opening 8 and the second sealing spiral ring opening 9 are tightly clamped together. At the same time, the fins 6 adjacent to the two ends of the fin protection box 5 are fixedly installed with the same movable connection fixing buckle 7, and finally the sealing chamber door 18 is covered, and then the bolt 19 is used to reinforce the seal, and then the sealing cover door 23 on the gas purifier 4 is opened to put the new filter plate 22 into the filter plate bracket 21, and then the sealing cover door 23 is closed;

[0035] After the device is installed, the air inlet pipe 16 is connected to the waste heat pipe to transport the hot gas to the waste heat recovery structure 2. At the same time, cold water is connected to the water inlet pipe 15 and transported to the waste heat recovery structure 2. The cold water and the hot gas are separated by a heat insulation sheet so as not to interfere with each other but are staggered and adjacent. Then, the cold water and the hot gas are subjected to heat exchange in the waste heat recovery structure 2 to recover the waste heat. After the reaction is completed, the hot water will be discharged into the water storage tank 3 through the metal pipe 14. At the same time, the reaction gas will also be discharged into the water storage tank 3 through the first air outlet pipe 17. At this time, the hot water will be discharged from the device through the water outlet pipe 28. The gas generated by the hot water and the gas discharged into the water storage tank 3 will be filtered by the gas purifier 4 and then discharged from the device.

[0036] When one of the fins 6 is damaged, there is no need to directly replace the waste heat recovery structure 2, nor is there any need to replace all the fins 6. It is only necessary to unscrew the two movable connection fixing buckles 7 adjacent to the damaged fin 6 on both sides, and then replace a new fin 6 and install it at the position where the damaged fin 6 was removed, and then screw and fix it by screwing the two movable connection fixing buckles 7 adjacent to the new fin 6 on both sides.

[0037] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0038] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.
