Description

Technical Field

[0001] This application relates to the field of waste gas, and more specifically to a high-temperature waste gas recycling device. Background Technology

[0002] Existing pipe insulation methods often involve wrapping the pipe with insulating cotton to ensure the fluid medium inside maintains a normal temperature. However, the insulation cotton typically covers the entire length of the pipe, which is labor-intensive for long pipes and cumbersome to remove. In contrast, if high-temperature waste gas pipes are located around the flange ends, the fluid medium inside the pipe can be heated by heating the pipe itself. Furthermore, if high-temperature waste gas pipes are located at both ends of the pipe, the middle section does not require insulation. Therefore, there is a need for a convenient, simple, and highly practical high-temperature waste gas reuse device. Summary of the Invention

[0003] The main objective of this application is to provide a high-temperature waste gas reuse device, wherein the high-temperature waste gas reuse device can effectively utilize its own structural configuration to achieve the advantages of high-temperature waste gas reuse.

[0004] Another objective of this application is to provide a high-temperature waste gas recycling device, wherein the high-temperature waste gas recycling device includes a pipeline assembly and a two-gas circulation assembly. The two gas circulation assemblies are disposed on the pipeline assembly. The pipeline assembly includes a first pipe body and a second pipe body, which are fixedly connected. Both the first pipe body and the second pipe body have a flange end, and the two flange ends are engaged by a plurality of annularly arranged bolts. The two gas circulation assemblies are respectively located on opposite sides of the two flange ends. The two-gas circulation assemblies are for high-temperature waste gas circulation, that is, the temperature of the fluid medium in the pipeline is increased by heating the pipeline. If high-temperature waste gas pipelines are arranged at both ends of the pipeline, the middle section of the pipeline does not need to be wrapped with insulation cotton, thereby reducing the length of insulation cotton that needs to be wrapped manually, and thus reducing labor consumption. At the same time, compared with the previous treatment of wrapping the entire pipeline, the manual removal of insulation cotton is also more convenient during the disassembly process.

[0005] Another objective of this application is to provide a high-temperature waste gas reuse device, wherein the high-temperature waste gas reuse device has a simple structure, is easy to operate, does not involve complex manufacturing processes and expensive materials, has high economic efficiency, and is easy to promote and use.

[0020] refer to Figure 1According to a preferred embodiment of the high-temperature waste gas recycling device of the present invention, it should be noted that the structure of the high-temperature waste gas recycling device is as follows: Figure 1 As shown, the high-temperature waste gas recycling device includes a pipeline assembly 10 and two gas circulation assemblies, which are mounted on the pipeline assembly 10. Specifically, the pipeline assembly 10 includes a first pipe body 11 and a second pipe body 12, which are fixedly connected. The connection method can be a bolted connection. Specifically, both the first pipe body 11 and the second pipe body 12 have a flange end, and the two flange ends are engaged by a plurality of annularly arranged bolts so that the two flange ends abut against each other.

[0021] It should be noted that each of the air circulation components includes a connecting ring 20, which is movably fixed to the outer wall of the first pipe body 11 or the second pipe body 12 and spaced at a predetermined distance from the corresponding flange end to reserve space for subsequent bolt installation or removal.

[0022] Specifically, the surface of the connecting ring 20 also has an annular protrusion 21, which has a plurality of evenly distributed first connecting holes and a plurality of evenly distributed second connecting holes. The plurality of first connecting holes and the plurality of second connecting holes are arranged in an annular array, and the plurality of first connecting holes and the plurality of second connecting holes are also staggered.

[0023] Furthermore, each of the aforementioned air circulation components includes an inlet pipe 31, an outlet pipe 32, an inlet ring 33, and an outlet ring 34. The inlet pipe 31 has a first connecting end, which is fixedly connected to the first connecting end. The outlet pipe 32 has a second connecting end, which is fixedly connected to the second connecting end. That is, external exhaust gas enters the inlet ring 33 through the inlet pipe 31 and is guided to the outlet pipe 32 through the outlet ring 34. The aforementioned fixed connection is implemented as a rotating sleeve, which is rotatably disposed at the first connecting end or the second connecting end. Its end is configured to be threadedly connected to the inlet pipe 31 or the outlet pipe 32. Similarly, the outlet pipe 32 can be disengaged from the first connecting end or the outlet pipe 32 can be disengaged from the second connecting end by rotating the rotating sleeve. Those skilled in the art should understand that the above-mentioned exhaust pipe 32 or intake pipe 31 is a slender metal tube that can be bent or pulled down to a predetermined length so that the connecting sleeve can be installed on the exhaust pipe 32 or intake pipe 31.

[0024] Furthermore, the intake ring 33 has a plurality of evenly distributed third connecting holes on the side facing the flange end, and the exhaust ring 34 has a plurality of evenly distributed fourth connecting holes on the side facing the flange end.

[0025] Furthermore, each of the air circulation components includes a plurality of fastening components 40, one end of each of the plurality of fastening components 40 is engaged with a plurality of the third connecting holes, and the other end of each of the plurality of fastening components 40 is engaged with a plurality of the fourth connecting holes. The end of the fastening component 40 engaged with the third connecting hole also passes through the corresponding first connecting hole, and the end of the fastening component 40 engaged with the fourth connecting hole also passes through the corresponding second connecting hole.

[0026] Specifically, each of the fastening components 40 includes a first connecting pipe 41, a second connecting pipe 42, and a third connecting pipe 43. Both ends of the second connecting pipe 42 are connected to the first connecting pipe 41 and the second connecting pipe 42, respectively. The first connecting pipe 41 and the second connecting pipe 42 are arranged parallel to each other, and the second connecting pipe 42 is arranged perpendicular to the first connecting pipe 41.

The first connecting pipe 41 also passes through the corresponding first connecting hole, and the third connecting pipe 43 passes through the corresponding second connecting hole. Furthermore, the second connecting pipe 42 is spaced a predetermined distance from the flange end.

[0027] It should be noted that insulation cotton is wrapped around the pipe assembly 10 to ensure the temperature at the pipe location. Simultaneously, external high-temperature exhaust gas passes through the air circulation assembly to raise the temperature of the pipe assembly 10. That is, the fluid flowing through the pipe assembly 10 is heated by the high-temperature pipe, and the insulation cotton wrapping the pipe surface prevents the temperature of the heated fluid medium from dropping too quickly, ensuring that it remains within a suitable temperature range when flowing to the predetermined location to meet the requirements of subsequent processes. Furthermore, the aforementioned insulation cotton placement area is as follows... Figure 1 The three sections A, B, and C are shown, and the insulation cotton at section C is secured with asbestos rope.
