On December 3, the two core equipment of the cold hydrogenation unit in Phase 1 of Ningxia Runyang Silicon Materials Technology Co., Ltd.’s project to produce 50,000 tons per year of high-purity polysilicon – the cold hydrogenation reactors (also known as fluidized bed reactors) – were successfully lifted into place. The project features 4 cryohydration reactors, each with a net weight of 217 tons and a height of 25 meters. Lifting is carried out using a 1,250-ton crawler crane as the main lift device and a 500-ton truck crane for assisting. On November 9, the first cryohydration reactor was successfully hoisted into place. Before the equipment arrived, the project team held a special meeting to finalize the lifting plan, and arranged for preparatory work in areas such as receiving the equipment, carrying out disinfection measures, lifting the equipment, sealing the frame structure, insulating the equipment and pipelines, installing the internal components of the equipment, and installing electrical and instrumentation systems. These preparations created the conditions necessary for the smooth lifting of the equipment and for subsequent work. After the equipment was lifted into place, the project team and the construction crew worked against time; through eight days and nights of continuous effort, they successfully completed tasks such as pipeline installation, insulation of the equipment and pipelines, installation of the internal components of the equipment, installation of electrical instruments, and completion of the framework structure. The lifting of the first cryohydration reactor took 3 hours and 15 minutes, while the lifting of the second cryohydration reactor took 2 hours and 30 minutes. The efficient lifting of these two reactors provided valuable experience for the lifting of the subsequent two units.
