Method for installing coke dry quenching electric distribution pipes and penetrating leads through electric distribution pipes

Abstract

The invention relates to a method for installing coke dry quenching electric distribution pipes and penetrating leads through the electric distribution pipes, belonging to the field of the metallurgical electrical equipment installation. The method for installing the coke dry quenching electric distribution pipes and penetrating leads through the electric distribution pipes comprises the following steps: laying hidden steel pipes, laying exposed steel pipes and ceiling inner steel pipes, penetrating leads through the steel pipes, and grounding the steel pipes. The method for installing the coke dry quenching electric distribution pipes and penetrating leads through the electric distribution pipes is characterized in that in the step of laying the hidden steel pipes, the steel pipes are heated, the steel pipes are cut, the steel pipes are threaded, the positions of a case and a box are tested, the case and the box are fixed, the steel pipes are connected, the steel pipes are distributed to the cast-in-place concrete, and ground leads are connected in a bridging way; in the step of laying the exposed steel pipes and the ceiling inner steel pipes, the preprocessed exposed steel pipesand the preprocessed ceiling inner steel pipes are heated and bent, a support and a hanging bracket are installed, the case, the box and the case and the box fixing positions are determined, the support and the hanging bracket are fixed, the case and the box are fixed, the exposed steel pipes and the ceiling inner steel pipes are connected, and ground leads are connected in a bridging way; and inthe step of penetrating leads through the electric distribution pipes, the strip leads are penetrated through the electric distribution pipes, the electric distribution pipes are cleaned, the leads are set out, cut and binded, the openings of the electric distribution pipes are protected, the leads are connected, and the insulation of the leads is controlled remotely.

Description

technical field [0001] The invention relates to the field of metallurgical electrical installation, in particular to a CDQ electrical pipe and an installation method for threading in the pipe. Background technique [0002] Dry coke quenching is a newly born smelting energy-saving technology in the world. Its English name is Coke Dry Quenching, or CDQ for short. CDQ uses circulating inert gas as the heat carrier, and the circulating fan sends the cold circulating gas into the red coke cooling chamber to cool the high-temperature coke to below 250°C and discharge it. The circulating hot gas after absorbing the heat of coke is introduced into the waste heat boiler to recover heat and generate steam. After the circulating gas is cooled and dedusted, it returns to the cooling room through the fan, so that the red coke is cooled in this way. The steam generated by the CDQ boiler is either integrated into the steam pipe network in the plant or sent to generate electricity. Dry c...

Problems solved by technology

The CDQ project includes the CDQ body, boiler, oxygen removal water supply station, CDQ dust removal, power generation system, circulating water pump room, operation room and control room, among which electrical piping and pipe threading are important parts in the power generation system. First, since CDQ technology is an emerging field, there are only a few domestic companies adopting this method, and the installation of CDQ equipment is still in the groping stage, and there are many unscientific and unreasonable places , the installation process is complicated
