Problems solved by technology
During the construction of the steelmaking OG dust removal system, the OG dust removal and release pipe is generally composed of three pipes connected by steel beams, multi-layer platforms and steel ladders. Due to the high height of the release pipe, it is difficult to hoist. If a single pipe is used for hoisting, then install it layer by layer Platforms and steel ladders not only require a lot of high-altitude operations, but also have high safety risks, labor and time-consuming, but also affect the construction period and increase costs

Embodiment
[0035] A steelmaking OG dust removal and release pipe modular installation method, comprising the following steps:
[0036] Step 1: First retest the base 1 of the release pipe 5. After reaching the standard, the surface of the base 1 is roughened, and the bases 4 of the three release pipes 5 are installed on the base 1 and put in place. A number of groups of backing plates 3 are evenly distributed in the circumferential direction of the anchor bolts 2 of 1;
[0037]Step 2: Set up an assembly site next to the installation position of the release pipe 5, and assemble the release pipe 5. The interface position of each release pipe 5 is set at a height of 1m from the platform 6 of each layer, and two adjacent sections of the release pipe 5 After the interface section is pre-assembled at the assembly site, the lower and upper ends of each section of the release pipe 5 are temporarily supported by a support member 8. After assembly, the assembled release pipe 5 is erected with two c...

The invention discloses a modular installation method of a steelmaking OG dedusting discharge pipe, which belongs to the technical field of installation of a steelmaking OG dedusting system discharge pipe. In the present invention, by first assembling the release pipe into sections and using supports to fix it at the designed angle, the angle of the release pipe during the hoisting process can be guaranteed so that it can be completely matched with the base or the release pipe in the lower section. During the installation process After aligning the platform with the corresponding relief pipe, select the relief pipe on the adjacent side for welding. At this time, the installation accuracy of this layer can be guaranteed, and the relief pipe on the other side is welded. Since one relief pipe has been welded, At this time, it is relatively simple and easy to complete the welding process, followed by welding the release pipe aligned with the platform, and then completing the rest of the welding work is relatively simple and easy, which greatly shortens the construction period and saves construction costs, and also reduces the overhead. job risk.
Description
technical field [0001] The invention relates to the technical field of installation of a discharge pipe for a steelmaking OG dust removal system, in particular to a modular installation method for a steelmaking OG dust removal discharge pipe, which is suitable for rapid installation of a steelmaking OG dust removal and release system. Background technique [0002] Existing steelmaking OG dedusting systems are equipped with release pipes, through which the air or gas inside the pipeline is discharged. When the pipeline is put into operation, use the release pipe to discharge the air in the pipe; when the pipeline or equipment is overhauled, the discharge pipe can be used to discharge the gas in the pipe to prevent the formation of explosive mixed gas in the pipeline. During the construction of the steelmaking OG dust removal system, the OG dust removal and release pipe is generally composed of three pipes connected by steel beams, multi-layer platforms and steel ladders. Due ...
