Background
Five committees of the ecological environment department and the like jointly print opinion on the ultra-low emission of the advanced implementation steel industry on 4 months in 2019, and the ultra-low emission modification of the steel industry formally opens a preamble. In 2020, the ecological environment department issues technical guidelines (revised 2020 edition) for making emergency emission reduction measures in heavy pollution weather major industries, and tightly connects performance grading standards of iron and steel enterprises with ultra-low emission. So far, the effect and the progress of the steel enterprises for completing the ultra-low emission transformation directly influence the production benefit and the future development of the enterprises.
The main method of the ultra-low emission reconstruction of the steelmaking engineering is to increase dust removing points to absorb the unorganized smoke dust in the factory building through newly constructing a dust remover and a dust removing pipeline, thereby playing a role in reducing pollutant emission. Because the process equipment in the steel-making workshop is very many, the layout is compact, and the diameter of the dedusting pipeline is very large, the ultralow-emission pipelines of many steel-making projects are selectively arranged on the roof of the steel-making workshop, but the installation of the dedusting pipeline also brings great difficulty. The conventional installation thought can assemble the dust removing pipeline on the ground, and then hoist the dust removing pipeline to the roof by means of a hoisting machine, but the method can be completed when the dust removing pipeline and the factory building are synchronously constructed, and for the built factory building, the dust removing pipeline is difficult to hoist in place directly because the dust removing pipeline is far away from the roof. Of course, the dust removing pipeline can be assembled in the factory building, then the mast is arranged on the roof, and the mast is used for hoisting the dust removing pipeline in place, but the method has high construction difficulty, belongs to irregular hoisting, and needs to dismantle the corresponding roof encaustic tiles and purlines, so that the construction period is long, and the normal production of equipment in the factory building is influenced.
Through searching, as disclosed in patent application No. 2020112465819, a synchronous construction method of a steel-making factory building and a roof large-caliber pipeline is disclosed, and a reasonable crawler belt refund route is selected before construction; the main construction procedures are as follows: closing each span roof, withdrawing the crawler crane from the roof closing span, installing a roof dust removing bracket, hoisting a section of roof dust removing pipeline in the crawler crane span, and continuing to close the roof and withdrawing the crawler crane from the roof dust removing pipeline. The scheme adopts a mode of synchronously constructing the roof of the steel-making factory building and the dust removing pipeline of the roof. As another patent application of application number 2019103877770, a sectional installation construction method of a large-diameter overlength pipeline across a roof is disclosed, and the pipeline is divided into a left-end pipeline, a roof-across pipeline and a right-end pipeline according to the span of the pipeline in a factory building; and correspondingly arranging a temporary bracket; the two ends of the temporary cross beam of the temporary support are supported by temporary upright posts, the cross roof pipeline is supported by the temporary cross beam, and the temporary upright posts are arranged on crane beams in the factory building; welding a left end pipeline, a roof crossing pipeline and a right end pipeline after hoisting; and finally, removing the temporary support. According to the scheme, the problems that a working face is narrow and a large crane cannot stand can be solved through sectional hoisting, but the setting and the dismounting of the temporary support are also in the current situation of high construction difficulty.
