Description

Technical Field

[0001] This utility model relates to the field of environmental engineering technology, specifically to a waste gas emission pipeline. Background Technology

[0002] Environmental engineering aims to improve environmental quality, protect natural resources and ecosystems, and promote the sustainable development of human society. Waste gas emissions refer to toxic and harmful gases emitted by humans during production and daily life. Pipelines are used to guide, transport, and discharge waste gases.

[0003] An environmental engineering waste gas emission pipeline with patent application number 202222050162.9 protects and insulates the waste gas transmission pipe with an outer frame and insulation layer to increase safety. However, during use, the long-term continuous transportation of high-temperature waste gas may accelerate the aging of the insulation layer, making it inconvenient to replace and affecting the insulation performance. At the same time, the waste gas emission pipeline is laid directly on the ground, and the bottom of the pipeline is in contact with the ground for a long time. When the ground is damp, it is easy to accelerate the corrosion of the pipeline and affect its service life. The bottom of the pipeline is close to the ground, making it difficult to observe and maintain the bottom, which increases the difficulty of operation. Utility Model Content

[0004] The purpose of this utility model is to provide an exhaust gas pipeline to solve the problems of inconvenience in connecting and replacing insulation materials and the fact that pipelines close to the ground are prone to accelerated corrosion.

[0028] Working principle: In use, the first lower frame 1 and the first upper frame 41 are respectively fitted onto the outside of the two heat insulation layers 2. The bottom of the first upper frame 41 is controlled to contact the top of the first lower frame 1, so that the four clamping plates 42 are inserted into the four clamping slots 43 respectively. This allows the first lower frame 1, the first upper frame 41, and the two heat insulation layers 2 to wrap around the gas pipe 6. The first lower frame 1 and the first upper frame 41 are easily connected and fixed by two sets of fixing plates 44 and bolts. When it is necessary to replace the heat insulation layer 2, the bolts are loosened from the fixing plates 44, and the first lower frame 1 and the first upper frame 42 are controlled to contact the top of the first upper frame 1. The upper frame 41 is separated to facilitate the removal and replacement of the insulation layer 2, ensuring the insulation effect. When the first lower frame 1, the first upper frame 41, the second lower frame 18, and the second upper frame 19 are connected and installed, the sealing effect is improved by the sealing ring 20. Pulling the control block 14 and the limit rod 15 upward causes the positioning frame 13 and the limit block 16 to compress the spring 17. Supported by the first connecting frame 7, the through groove 8, and the connecting column 9, the mounting plate 10 is pulled towards the second connecting frame 12. When the mounting plate 10 is inserted into the inner side of the second connecting frame 12, the positioning hole... When the positions of the through holes of the second connecting frame 12 and the positioning frame 13 are aligned, the pull on the control block 14 is released. Under the action of the spring 17, the limit rod 15 is driven to reset, so that the limit rod 15 is inserted into the positioning hole 11, thereby limiting and fixing the mounting plate 10. The first lower frame 1, the first upper frame 41 and the second lower frame 18 and the second upper frame 19 can be installed or removed in a convenient manner. Multiple sets of support frames 3 and the base plate 23 are installed and fixed on the ground. The bottom of the first lower frame 1 and the second lower frame 18 is adjusted by multiple sets of adjusting plates 53 and two support rods 52. The system is fixed and supported, and controls multiple motors 22 to start and run synchronously. Driven by the motors 22, the connecting rod 21 drives the threaded rod 54 to rotate under the support of the fixed block 25. This causes the adjusting plate 53 to move up and down under the limit of the stabilizing rod 24, which in turn drives the first lower frame 1 and the second lower frame 18 to rise and fall. This, in turn, causes the support rod 52 to slide under the support of the support plate 51, which improves the stability of the lifting adjustment, facilitates the adjustment of the distance between the first lower frame 1, the second lower frame 18 and the ground, avoids close contact with the ground, reduces corrosion, and facilitates daily inspection and maintenance.
