In this year's list of China Top Brand Products, Zhongsheng Group's high-efficiency energy-saving heat exchangers were successfully selected. Less than 10 years after its establishment, Zhongsheng Group achieved a leap in scale and quality with its own innovation and accurate product positioning.
Turn traditional products into featured products
The industry depends on "people". Guo Hongxin said that the group pays special attention to the framework of the talent system and has actively introduced high-level overseas Ph.D. and well-known experts and established the “High-efficiency Heat Transfer Research Institute†on the basis of having more than 300 technicians. The Group also joined forces with Nanjing University of Technology to apply for the "Jiangsu Province Energy Saving and Environmental Protection Equipment Engineering Center" to truly create a "community" of production, education and research centered on enterprises.
Right now, another "Salt and difficult wastewater treatment" technology introduced by the Shengli Group has been put into use to undertake the wastewater treatment project of China's largest coal company Shenhua Group's national coal-to-oil project.
The surface of an ordinary heat transfer tube looks like a metal tube that is smooth inside and outside. The heat exchange tube of Zhong Sheng Group adds a lot of rough lines inside and outside the tube wall. This seemingly small change greatly improves the heat transfer efficiency. Small innovations filled the domestic gap.
Guo Hongxin, chairman of China St. Group, called this transformation of traditional products "innovation on the shoulders of giants," which is to combine new technologies with traditional chemical equipment manufacturing to ensure that equipment products meet stable operation. Let customers feel the benefits of new technologies. Over the years, Zhongsheng Group has created a number of national patents in the process of turning traditional products into its own specialty products. Initially, many of the company’s R&D products were to “take in†the technologies of Japan, the United States, and other countries to digest, absorb, and innovate. In the end, they not only replaced imported products, but also advanced technology. Guo Hongxin said that this innovation not only saves the company's basic research links, but also significantly shortens the time for technological innovation.
For good foreign new technologies and new products, the company's approach is to "introduce, digest, absorb, and innovate," so that the products we manufacture are more perfect than those of foreign original products. Guo Hongxin mentioned that although the equipment is manufactured according to the production process of foreign companies, the core technology of manufacturing is our own.
Each year, Zhongsheng Group has two or three patented products with independent intellectual property rights. The annual research funding accounts for more than 5% of the total investment of the company. R&D designers account for nearly one-third of the total number of employees. At the same time, the company has also built laboratories, postdoctoral workstations, and engineering research centers with universities such as Nanjing University of Technology, Southeast University, and Jiangsu Institute of Technology, which constitutes a strong backing for the company's R&D system.
In the past few years, Guo Hongxin and his team invented a series of patented achievements, including: high-temperature insulated sliding tube support, ultra-low temperature cold tube support, high pressure and ultra-high pressure shock tube support, high temperature separation heat pipe heat exchanger, efficient ripple Tube Condenser, Efficient External Solenoid Heat Exchanger, Efficient Corrugated Pipe Reboiler, High Heat Flux Heat Exchanger, High Efficiency T-Tube Heat Exchanger, Low Temperature Hot Rod with Center Temperature Tube, and Torch Gas Recovery Emissions Automatically Controlled Water Seal Valve System, Upright Air Resistance Heat Precipitator Tube Air Preheater, Acid Gas Combustion Discharge Torch Head, Spiral Corrugated High Efficiency Heat Exchanger, Inner Recessed Structure High Efficiency Heat Exchanger, Efficient Hot Rod, New Type Spiral Plate Exchange Heat exchangers, spiral baffle heat exchangers, high efficiency waste heat boilers, efficient heat insulation tubes, etc.
Under the leadership of Guo Hongxin, Zhongsheng Group Jiangsu Zhongsheng High-tech Industry Co., Ltd. won the “Outstanding Private Enterprise in Nanjing in 2005â€, “Advanced Unit for the Construction of New Nanjing in 2005â€, and “Outstanding Key Enterprise in Nanjing Environmental Protection Industry in 2004â€. , "the contract and trustworthy enterprise" and other honorary titles, and become a service in the petrochemical, petroleum, metallurgy, electric power, transportation, environmental protection and other industries set R & D, design and product manufacturing as one of the high-tech enterprises, total assets of 200 million Yuan, annual sales of more than 500 million yuan.
In the past year or so, Zhongsheng Group has undertaken many tasks related to the design and manufacture of foreign-related projects. During this process, the company has implemented a number of foreign company standards in addition to GB150, GB151, and ASME standards. For example, in cooperation with South Korea’s Samsung Engineering Co., Ltd., Samsung’s corporate standards were implemented; and in cooperation with Disim Engineering’s SASOL project in Lianyungang, the company’s corporate standards were implemented; each was designed and manufactured for Yangzi BASF. In the heat exchangers, BASF’s corporate standards were adopted; in the China Taiwan Zhongding project, UOP’s corporate standards were implemented; in order to undertake the PT investment in Belgium, PTA expansion projects, the company also passed the export of European projects PED (Pressure Equipment Directive) Evaluation.
The implementation of these foreign-related enterprise standards, PED assessment, and the design and manufacturing of foreign-related projects provided a high-level exchange platform for the company. It not only gave a new understanding of advanced foreign enterprise standards, but also allowed the company to accumulate rich theories and Practical experience will also improve the company's corporate standards, improve the company's design and manufacturing standards, and create conditions for undertaking more foreign-related projects in the future.
Technological innovation is fundamental to business survival So far, one of the technological achievements that Zhongsheng Group is most proud of is the hot-rod technology that successfully solves the problem of deformation of the roadbed in the permafrost region of the Qinghai-Tibet Railway. This technology has solved the problems that have plagued the construction of the Qinghai-Tibet railway for more than 40 years, and has also protected the natural ecological environment and resources of the frozen earth area. At present, low-temperature hot rods have been designated as the only technical reserves for the treatment of frozen damage to the Qinghai-Tibet Railway.
Guo Hongxin told reporters that his opportunity actually came from a television program. In 2002, when Guo Hongxin watched the “Dialogue†section of the CCTV, the topic of this issue was just about the construction of the Qinghai-Tibet Railway. Someone asked the Deputy Minister of Railways Sun Yongfu how to solve the problem of the frozen earth in this no man’s land in Kekexili. Yongfu replied that he was prepared to adopt foreign heat bar technology.
Seeing Guo Hongxin's heart startled here: This is exactly the subject of our research, and it has already been very successful! With this thought in mind, Guo Hongxin could no longer sit still. On the night of the same day, he wrote a letter and wrote to Minister Sun Yongfu: "The Chinese people are fully capable of using their own techniques to solve the problem of frozen soil." A week later Guo Hongxin Received a reply from Minister Sun, asking him to go to Beijing with relevant information to reply.
People who have watched the movie "Kekexili" know that the thicker ice in Hoh Xil is a bitter cold place where grass is not born and living conditions are poor, and this place is also a necessary place on the Qinghai-Tibet Railway. The thickness of the ice in the Kekexili section reaches tens of meters or even hundreds of meters all the year round. Frozen soil freezes in winter and disappears in summer. The roadbed is extremely unstable. The key to the success of the Qinghai-Tibet railway construction is to solve the problem of frozen soil, which is a world-class engineering problem.
At the end of 2002, Guo Hongxin sent his own researched and developed thermal rods to the Kokili Permafrost area for experiments and achieved initial results. After being commissioned by the Qinghai-Tibet Railway Engineering Command, Guo Hongxin organized scientific and technical personnel to engage in technical research and established the largest 18-meter-high heat pipe test stand in China and a production line that annually produced 100,000 heat bars, and developed a national patent with excellent performance. The product "low temperature hot rod with central temperature measuring tube" has undergone special anti-corrosion treatment and its service life can reach more than 30 years. Subsequently, entrusted by the Ministry of Railways' Qinghai-Tibet Railway Headquarters, Zhongsheng Group was responsible for drafting the “Technical Guidelines for Using Hot Rods in the Permafrost Engineering of the Qinghai-Tibet Railway†standard.
In the frozen area of ​​Hoh Xil, Guo Hongxin and his team instructed the construction staff to insert a hot rod at a depth of 7 to 8 meters. When the Qinghai-Tibet Railway was opened on July 1, 2006, tens of thousands of hot rods had been neatly arranged on both sides of the railway. In the next few years, hot-rods will be inserted step by step in the 550-kilometer permafrost zone. This is the first large-scale use of hot-rod technology in China to solve the problem of stability of the subgrade in permafrost railways in high-altitude cold regions.
Guo Hongxin said that the hot rod cooling technology is a system that uses liquid-vapor conversion convection and circulation to achieve heat transfer, and is the device with the highest heat transfer efficiency in a passive cooling system. It has the characteristics of large heat transfer capacity, small heat transfer temperature difference, low start temperature, good temperature uniformity performance, one-way heat transfer, safety and economy, etc. This kind of one-way thermal conductivity thermal rod has a heat transfer rate of 1000 copper rods. ~10000 times. Guo Hongxin said: "Now the thermal rods of the Qinghai-Tibet railway in the Kekocili permafrost region have officially entered the stage of engineering use. Our hot rod technology has been leading the world for 10 years and has already begun exporting to Russia and India." Guo Hongxin is very proud of this.
In China, permafrost accounts for 22.3% of the country's land area and ranks third in the world, among which high-altitude permafrost area ranks the highest in the world. Hot-rod technology effectively solves the problem of subsidence and subsidence of roadbed in permafrost regions in summer. It can save more than 30 million yuan per km for the bridge-generation road, and it can save more than 1 billion yuan if only the total investments of the Qinghai-Tibet Railway adopt hot-rod technology. Yuan, at the same time avoiding the destruction of the surface of the frozen soil ecological environment and resources caused by human activities such as surface excavation, removal of vegetation, construction of embankments and soil. With this world-leading low-temperature hot-rod patented technology, Zhongsheng Group has become famous.
Hot-rod technology is just one of more than 30 patented technologies of China Sheng Group. Looking back at the history of entrepreneurship in the past 10 years, Guo Hongxin, who once taught 15 in colleges, has a unique understanding: “The scientific research achievements of universities and colleges strive to be theoretically perfect. It indicates the direction for product research and development; for enterprise innovation, perfect theory must be adapted to the market. Needs, this is the most effective mode of transformation of scientific and technological achievements."
In the face of tremendous successes in innovation, Guo Hongxin’s understanding of innovation remains pristine: “Innovation is not a complicated concept, it is a process that actually solves problems.†Zhong Sheng Group was founded for 9 years and has more than 30 national patents. A patent is the result of solving the problem; each patent has realized industrialization and has created the core competitiveness of the company.
Zhongsheng Group's innovation platform is constantly improving. In recent years, the company has provided services for the United States General Electric, Germany BASF and other international companies. Under the supervision of a German expert, Zhongsheng Group produced the largest heat exchanger in Asia with a diameter of 4250 mm and a weight of 98 tons. In the project cooperation, Guo Hongxin and his team also improved the efficient special tube heat transfer technology and applied for a number of patents. He still said humbly: “Although we have combined high-efficiency heat transfer with high-end materials and high-tech materials in the traditional equipment manufacturing industry to help customers reduce costs and solve some problems, chemical equipment is worth 100 billion yuan each year. The value of production, what we do is just the tip of the iceberg."
