Recently, the China Nonferrous Metals Industry Association announced the 2020-2021 China Nonferrous Metals Industry Quality Engineering Commendation List, and the "Sodium Aluminate Solution Evaporation System" project of Guangxi Huasheng New Materials Co., Ltd., which was contracted by Henan Jiuye Chemical Equipment Co., Ltd. and Guiyang Aluminum and Magnesium Design and Research Institute Co., Ltd., was rated as a high-quality project in China's nonferrous metals industry.
On March 28, 2019, Henan Jiuye Chemical Equipment Co., Ltd., as the general contractor, was responsible for the process design, equipment design and production, on-site overall installation, commissioning and operation of the "sodium aluminate solution evaporation system" project of Guangxi Huasheng New Materials Co., Ltd. for the new 2 million tons of alumina project.
At the beginning of the contracting, Henan Jiuye Chemical Equipment Co., Ltd. attached great importance to the establishment of a project team headed by the general manager, with the chief engineer, the director of the technical department and the director of the production plant as the professional person in charge, and went all out to invest in the whole process management of the project. In the design and production process of the project, the company's patented technologies are adopted: seven-effect two-stage split falling film evaporation technology, new film distributor, new mist remover and primary condensate heat exchange technology, etc., to ensure that the material liquid of the seven-effect split falling film evaporator is fully involved in the film distribution, and the film is more uniform and not blocked; The separated secondary steam does not carry the material; The raw steam condensate is fully recovered. After entering the site, the project team arranged the progress of the project in an all-round scientific and meticulous manner, prepared a scientific and targeted construction plan, and worked together with Party A, supervision and other units to overcome the impact of local high temperature and wet rain weather. In particular, the weight of the evaporator is 280 tons, which is the heaviest equipment in the entire alumina project, how to safely hoist in place is a difficult problem, we use a 500-ton crawler crane and a 350-ton truck crane combined with a combined composite hoisting method, and safely place the evaporator in place. It has been highly praised by Party A. And it solves the problem of heat treatment of super-large equipment, and effectively eliminates the alkali embrittlement of equipment. After the completion of the project, the feeding was successful at one time, and all the indicators of operation met the design requirements.
Winning this high-quality engineering award is a great affirmation and spur to our work, we will take this opportunity to increase technological innovation, continue to explore around the seven-effect split falling film evaporator, research and development of newer and better practical technology, all for the sake of users, for the sake of users, build a project, set up a monument, make a friend, and make greater achievements in new projects.
