As one of the pillar industries of the national economy, the problem of high energy consumption in the cement industry has always plagued all parties in the industry, and the fan equipment in the common process system is a major energy consumer, accounting for more than 30% of the total production energy consumption, which seriously restricts the cost reduction and efficiency enhancement of cement enterprises.
In recent years, the demand for cement has declined significantly, and the market competition is fierce. Continuous cost reduction has become the key for enterprises to gain competitive advantage. To this end, China Cement Network and Li Yongsheng, chief scientist of Shandong Tianrui Heavy Industry Co., Ltd., exchanged in detail on the opportunities and challenges brought by the current cement industry environment to equipment manufacturing enterprises and the application of Tianrui Heavy Industry Maglev Power Energy-saving Technology in the cement industry. Li Yongsheng
, chief scientist of
Shandong Tianrui Heavy Industry Co., Ltd., was born at the right time. Maglev technology greatly reduces energy consumption
in cement production. During the conversation, Li Yongsheng told China Cement Network that cost saving has become an important part of its survival and development. Coupled with the promotion of China's "double carbon" goal, enterprises using high energy consumption equipment are under great pressure, and the enthusiasm of choosing energy-saving equipment is relatively high, which brings opportunities for equipment manufacturing enterprises with full advantages in energy saving.
Of course, the challenges brought by the current cement industry environment to equipment manufacturing enterprises can not be ignored.
Li Yongsheng said that for the cement industry, developing products more suitable for users and forming a package of solutions is an important direction for future development.
According to Li Yongsheng, Tianrui Heavy Industry Maglev Power Energy-saving Equipment is a new generation of high-efficiency energy-saving and environmental protection equipment independently developed based on four core technologies, namely, active magnetic bearing, high-speed permanent magnet synchronous motor, three-dimensional flow impeller and intelligent operation and maintenance management system.
At present, Tianrui Heavy Industry mainly applies magnetic suspension power energy-saving technology to kiln head, kiln tail coal feeding fan, primary fan, cement silo, homogenization silo bottom fan and so on, which plays an important role in reducing energy consumption of cement enterprises.
Talking about the advantages of magnetic levitation power energy-saving technology, Li Yongsheng introduced that the first is energy-saving, compared with traditional equipment, magnetic levitation power energy-saving equipment saves 30% of electricity on average; The second is long service life. Due to the wear problem of ordinary fans, the accessories need to be maintained and replaced regularly, while the magnetic suspension blower has no wear during operation, and the design service life can reach 20 years. The third is low noise. The noise of magnetic suspension power equipment is below 80 decibels, which ensures the occupational health of employees and reduces noise pollution. In addition, the advantages are also reflected in oil-free, intelligent, maintenance-free and other aspects, which provide important technical support for the realization of the "double carbon" goal.
In the list of typical cases of the development of the Internet of Things enabling industry in 2023 published by the Ministry of Industry and Information Technology, Shandong Tianrui Heavy Industry's "High-efficiency Intelligent Magnetic Suspension Blower Based on Internet of Things Technology" was successfully selected.
Magnetic suspension blower
was selected as the list
of typical cases of the development of the Internet of Things enabling industry in 2023. Ten years of hard work has yielded fruitful results
. In fact, when it entered the field of magnetic suspension, Tianrui Heavy Industries has achieved success in the field of rock drills. However, they are not satisfied with the immediate achievements and resolutely choose to promote the industrial application of energy-saving technology of magnetic levitation power.
To this end, Li Yongsheng said that he had served as deputy chief engineer and deputy general manager of technology in a large state-owned enterprise in the past, and had made great contributions to the construction of high-speed rail. Fifteen years ago, he led the team to settle in Weifang and founded Tianrui Heavy Industries. Because of the incomparable energy-saving effect of magnetic levitation technology, while doing a good job in rock drilling machinery, we have invested heavily in the R & D and production of magnetic levitation equipment, and eventually become the leading enterprise in China's magnetic levitation industry, especially in the cement industry, which has occupied 70% of the market.
Li Yongsheng believes that the core of the current performance lies in the unremitting efforts of the R & D team. It is understood that Tianrui Heavy Industries has established Shandong Maglev Industry Technology Research Institute, which now has more than 200 R & D teams and 7 research institutes.
"Our research and development should be the leading one in China, the National Enterprise Technology Center, or the Secretariat Unit of the National Working Group on the Standardization of Maglev Power Technology Foundation and Application.". On the basis of a large number of innovative practices, we took the lead in combing the theoretical framework of magnetic levitation power technology and put forward the standardization system architecture. This is a major breakthrough in China's standardization construction and is of great significance to promote the development of maglev industry. Li Yongsheng said.
As a deputy to the National People's Congress, Li Yongsheng also put forward the proposal that maglev power energy-saving equipment should be included in the encouragement category of the national industrial structure adjustment catalogue, which was adopted by the state. Maglev power equipment has become an important technical support for China to achieve the goal of "double carbon".
It is worth mentioning that the current cement industry is facing great pressure to reduce carbon emissions, and is expected to be incorporated into the national carbon emissions trading market soon. As a major carbon emitter, the industry needs to increase carbon emission reduction efforts.
In view of the impact of the launch of the national carbon emission market on the cement industry, Li Yongsheng pointed out that carbon emission is a global issue, in which China has embodied the responsibility of a big country, and has also made a solemn commitment that carbon will peak in 2030 and be carbon neutral in 2060. Under the premise of the national strategic layout, all walks of life should come up with a timetable for carbon emissions, and the cement industry is no exception.
"Energy saving and carbon reduction is the key task of the cement industry, which is both a pressure and an opportunity for the industry. Whoever solves it well will get rapid development," Li Yongsheng said, "and our magnetic levitation power energy-saving equipment can provide strong support for energy saving and carbon reduction in the cement industry.".
In order to promote the green development of industry, the Ministry of Industry and Information Technology and other relevant departments have issued special documents in recent years, focusing on promoting the application of energy-saving technologies such as maglev in the industrial field. Therefore, the future application prospect of magnetic levitation technology is very broad.
In view of the trend of green and low-carbon development in the cement industry, Li Yongsheng introduced the future development plan of Tianrui Heavy Industries to China Cement Network.
He said that Tianrui Heavy Industries will further promote the R & D and application of magnetic levitation power energy-saving technology in the cement industry, innovate and develop more high-efficiency energy-saving equipment, provide technical support for energy-saving and carbon reduction in the cement industry, and contribute to the green, low-carbon and high-quality development of China's economy.
