Recently, the desulfurization tower shell for the Hehai New Energy Lanzhou Clean and Smart Heat Source project was successfully lifted and placed precisely in the designated area, laying a solid foundation for the subsequent full installation of environmental protection equipment. This project is a key measure for Lanzhou City to advance the clean and intelligent upgrading of its heating systems, and it holds great significance for improving the level of the city’s infrastructure. The desulfurization tower shell to be lifted this time is massive, with a total length of 26 meters, a diameter of 4.4 meters, and a weight of 34 tons; it was lifted in segments. The 50-square-meter work area at the project site is located adjacent to the boiler frame and the heat pump room, which imposes extremely high demands on the precision and safety of lifting operations. To overcome this challenge, the project team adopted a construction method of \"prefabrication on the ground and installation in the air\", carrying out key processes such as welding of the cylinder body and pre-assembly of components on the ground first, thereby reducing the need for work at heights ； During the lifting process, the team deployed a 130-ton truck crane and simultaneously employed an innovative \"ground-to-air\" relay method; through precise scheduling, it was successfully possible to quickly adjust the orientation of the cylinder by 90 degrees in the air. After hours of careful operation, the cylinder was finally placed in position steadily, with the error kept to an extremely low level. Compared to traditional methods of lifting individual components, this innovative construction approach offers significant advantages: on-site work is reduced by 60%, and the construction time is shortened by 40%. This effectively reduces various risks associated with construction in winter, achieving a balance between efficiency and safety. The successful lifting of the desulfurization tower shell not only demonstrates the company’s team’s strong professional skills and efficient project management capabilities, but also illustrates vividly the perfect integration of precision and efficiency in modern engineering construction. Next, the project team will use this as an opportunity to steadily advance the subsequent construction work, aiming to create a model project for clean and intelligent heating systems.
