[Haichuan New Energy] The distillation tower of Yunnan Tongwei Phase II 200,000-ton high-purity crystalline silicon project is in place for the first time
Thread Content
On June 15, the distillation tower of Yunnan Tongwei Phase II 200,000-ton high-purity crystalline silicon project was lifted into place for the first time.
There are a total of 18 distillation towers in the distillation unit of this project. The lower section of the 301a tower hoisted this time is about 370 tons. Its size is Φ7400mm×47233mm, which is the largest single section weight among the distillation towers. The hoisting method adopts a single-host lifting and delivery method with a 1000t crawler crane as the main crane and a 650t crawler crane as the tail truck. After the two vehicles lift the equipment horizontally, the main crane slowly raises the height, and the tail crane delivers it forward steadily, and finally it is in place "safely, smoothly, orderly and efficiently".
On July 26, 2021, the last distillation tower T0308a of the first phase of the Yunnan Tongwei project was successfully decoupled, marking the successful completion of the hoisting work of the distillation tower device, the core equipment of the project, and significant progress in project construction.
