en.Wedoany.com Reported - On June 4, the first 7.6-meter top-charging coke oven complete set in China, developed by Taiyuan Heavy Machinery Group Co., Ltd. (hereinafter referred to as "Taiyuan Heavy Industry Group"), has been operating smoothly for 1,300 days since its official commissioning. This further consolidates Taiyuan Heavy Industry Group's leading position in the coking equipment field, demonstrates its independent research and development capabilities, and provides a replicable "Taiyuan Heavy Industry Group solution" for the large-scale, green, and intelligent transformation and upgrading of the coking industry.
According to reports, the 7.6-meter top-charging coke oven equipment is equipped with a coal charging car, a pusher car, a coke guide car, a self-propelled coke bucket transport car, a non-propelled coke bucket transport car, an oven door service car, a hydraulic switching machine, and other coke oven machinery. During the design phase, the Taiyuan Heavy Industry Group R&D team, guided by principles of refinement, internationalization, high-end development, and intelligence, and premised on product reliability and technological advancement, with intelligence, greenness, and humanization as starting points, broke through multiple technical bottlenecks. This equipment achieves unmanned operation, online management, efficient operation, fault warning, and safety supervision of the complete set, solving the problem of efficient capture of smoke and dust throughout the entire coking cycle. A relevant person in charge of Taiyuan Heavy Industry Group stated that the 7.6-meter top-charging coke oven equipment has reached internationally advanced levels in terms of coke oven machinery, process equipment, automation, and environmental protection.
At the user project site in Yunnan, the factory building is nestled among green trees, with harmonious coexistence between humans and nature, and the 7.6-meter top-charging coke oven equipment is operating at full capacity. "Using ore without seeing ore, using coal without seeing coal, transporting materials without seeing materials, and producing without seeing dust" is not magic, but a technological achievement of Taiyuan Heavy Industry Group.
On-site staff member Qin Lihui stated that Taiyuan Heavy Industry Group manages the coke orderly, ensuring no smoke, dust, or odor on site. Wu Guoqiang, Director of the Coking Equipment Research Institute at Taiyuan Heavy Industry Group Technology Center, said: "By studying the smoke and dust emission patterns of each process, we established a high-temperature flue gas buoyant jet diffusion model and a dust collection efficiency coupling analysis model. This allowed us to develop a full-cycle efficient smoke and dust treatment system for the coking process for this equipment, innovating the design method of the dust collection system, achieving complete dust collection, efficient capture, and strict purification." Thanks to the technical support from Taiyuan Heavy Industry Group, the user was successfully selected as a national-level green factory.
In terms of intelligence, Taiyuan Heavy Industry Group developed an unmanned operation intelligent control system for the 7.6-meter top-charging coke oven equipment. Wu Guoqiang introduced that this system includes three major subsystems: ground coordination, wireless communication network, and vehicle intelligent control. It integrates ten functional modules: rapid travel and precise positioning, interlocking control, video monitoring, data management, safety protection, health management, fault diagnosis, emergency handling, human-machine interaction, and intelligent control, ensuring the safe and efficient operation of the coke oven equipment without operators.
The Taiyuan Heavy Industry Group R&D team also created a multi-functional collaborative control technology for efficient operation of coke oven equipment. This technology achieves intelligent and efficient operation of coke oven equipment through coordinated control of multiple devices and efficient operation of a single device. For example, it improves operational efficiency through rapid travel and precise positioning, intelligent door closing, etc., and achieves rapid fault identification and prediction through functional modules such as health management and fault classification and identification.
Furthermore, Taiyuan Heavy Industry Group established a safety management system with a three-level management mechanism of monitoring, prediction, and information feedback. The safe operation of coke oven equipment is jointly achieved through functions such as safety protection, interlocking control, and video monitoring. The coke oven safety protection system establishes a three-level safety protection mechanism: safety monitoring, safety prediction, and safety alarm feedback. The interlocking control system, through wireless transmission communication technology, ensures the safe and reliable operation of each unit of each vehicle according to the automation logic control requirements for unmanned vehicle operation. The video monitoring system achieves real-time remote information collection and display, ensuring production safety.
In recent years, Taiyuan Heavy Industry Group has continuously combined intelligent integration technology to enhance equipment performance. From 4.3-meter to 7.25-meter stamp-charging coke ovens, and from 4.3-meter to 7.6-meter top-charging coke ovens, Taiyuan Heavy Industry Group has formed a full series coverage of heat recovery, stamp-charging, and top-charging coke oven equipment, with manufacturing technology leading the same industry in China. Intelligence and greenness are inevitable trends in the development of coke oven technology. In the next step, Taiyuan Heavy Industry Group will develop large-scale coke oven complete sets equipped with unmanned operation intelligent control systems and full-cycle efficient smoke and dust treatment systems for the coking process, promoting the coking industry towards "green, high-end, intelligent, and advanced" development, contributing to the high-quality development of the high-end equipment manufacturing industry and the achievement of the "dual carbon" goals.
