Recently, the Department of Industry and Information Technology of Henan Province and the Department of Finance of Henan Province issued a notice on announcing the list of the first set major technical equipment certification in Henan Province in 2023，the “ZJG8/300M³ digester researched and developed and produced by China United Equipment Group Anyang Machinery Co., Ltd. (hereinafter referred to as Anyang Machinery) is listed among them, and it is the only one selected as the first set major technical equipment of Anyang City.
In recent years, Anyang Machinery has continued to explore and innovate, increase the research and development of leading products paper pulping equipment, and the product performance and production capacity are greatly improved. The diameter of ZJG8 type 300M³digester is 4600mm, it is the largest diameter limit of domestic land transportation, and it is the first product with the largest volume and the whole transportation in China. It has passed the testing and identification of the National Quality Supervision and Testing Center with CMA qualification, and the same type of products have not appeared in the domestic market, so it has unparalleled competitive advantages in the domestic and foreign markets.
This digester adopts replacement cooking technology, and establishes a completely enclosed waste heat and exhaust gas recovery system to reduce the degree of vulcanization and exhaust gas emission. The vulcanization degree of traditional batch cooking is 25%, while the replacement cooking only needs about 15%, which is about 10% lower than traditional cooking, and greatly reduces the pollution of sulfur-containing odors to the environment, the net amount of available alkali added is also reduced by 1-2% compared to traditional processes. Upgrade the cold blow cooking technology to fully recover the heat of steam, and the steam consumption is about 1/3 of that of traditional cooking, and the energy-saving effect is significantly improved. The pulping process adopts automatic management, which better solves the technical problems such as bias flow, tank level prediction, and anti-blockage prediction of the pot putting process, realizes advanced prediction, pays attention to the prevention of failures, makes the operation process smoother, reduces human intervention, and is conducive to the stability of output and quality.
The identification of the first set major technical equipment in Henan Province is an affirmation and encouragement of Anyang’s mechanical technology innovation work. Scientific and technological innovation is endless, we will take the recognition of the first (set) major technical equipment as an opportunity, unswervingly take the road of sustainable development driven by independent research and development and innovation, continue to increase product research and development, comprehensively promote technological innovation and process innovation, greatly improve product technology content and core competitiveness, provide strong technical support for continuing to stabilize the domestic market and deeply explore foreign markets, and effectively promote the high-quality, high-level and rapid development of enterprises.
