After more than a year of hard work, the energy-saving drying engineering research center of the Shandong Academy of Sciences developed a major energy-saving 600,000 tons of PTA (pure terephthalic acid) drying domestic equipment, theoretical models and industrial prototypes have been completed. The device is 4.2 meters in diameter and 42.5 meters in length, and is being demonstrated by Yangzi Petrochemical. After mass production, it will break the long-term foreign monopoly of large energy-saving drying equipment.
Energy-saving drying technology is widely used in the chemical, petrochemical, pharmaceutical, building materials, light industry, feed, food, paper, wood, food and other industries. Due to the monopoly of foreign technology, large-scale dryers rely on imports for a long time. In addition, drying is still a huge energy-consuming industry. Its energy consumption accounts for about 12% of the total energy consumption of China's national economy. At present, the domestic energy utilization rate of drying technology is only 40% to 50%, and foreign countries reach 70% or more.
On May 11th, the Center's chief expert, Shi Yongchun, said in an interview with reporters that this device digested and absorbed foreign technology. It was not only comparable with foreign products on the technical level, but also reached a 70% energy efficiency. There are more than 20 domestically-made installations planned for domestic use.
Not only in the PTA drying area. The Soda Ash Calcined and Dryed Large-scale Internally Heated Fluidized Equipment developed by the center in cooperation with Shandong Haihua Group is 18 meters high. It is the largest energy-efficient drying equipment in China. After seven sets of applications in Haihua Group, it replaced the import and has been in the country. Promote more than 60 sets, leading the market share. Cooperated with CNPC Liaohua Branch to develop large-scale adipic acid fluidization drying technology and equipment to reach the international advanced level, energy utilization rate reached 75%, and is being built by Shandong Hongye Group, Shandong Haili Company and Xinjiang Tianli Group. .
Shi Yongchun stated that the key to solving this problem in the Provincial Academy of Sciences is to build a platform for the Energy Saving Drying Engineering Research Center. According to reports, this is an open platform that works as a link to enterprises and universities. Scientific research is guided by the needs of enterprises, and through the successful transformation of scientific and technological achievements in leading enterprises in the industry, the promotion of advanced energy-saving drying technologies in the entire industry has been promoted.
The reporter learned that the center not only “marries” with more than a dozen colleges and universities, research institutes and design institutes at home and abroad, but also with large-scale enterprise groups such as Shandong Haihua, PetroChina Liaohua Company, Qingdao Haijing Group, and Shanalu Company. To establish cooperation. In order to accelerate the industrialization of scientific research results, the center has incubated Shandong Tianli Drying Equipment Co., Ltd. as a carrier for the mid-term ripening of the scientific research achievements of the engineering center. At present, this kind of engineering center-incubation model enterprise-service industry model has formed a complete research, incubation, demonstration and promotion innovation system.
It is reported that at present, the center has researched and developed more than 1,000 sets of drying technology and equipment to serve industrial production. The benefits of energy saving and investment saving have exceeded 10 billion yuan, and more than 800 enterprises have been promoted.

For XCMG Cylinder Seal Kit

The XCMG hydraulic cylinder repair kit is mainly used in the hydraulic systems of engineering machinery such as XCMG excavators and loaders, for repairing the seals of hydraulic cylinders.
Hydraulic cylinders are an important component of the hydraulic system of construction machinery, used to convert hydraulic energy into mechanical energy,
Convert the pressure of hydraulic oil into linear or rotational motion to drive various working components of construction machinery. The sealing components of hydraulic cylinders are key components to ensure their normal operation. If the sealing components are damaged or aged, it can lead to hydraulic oil leakage, hydraulic cylinder failure, and other problems, affecting the normal operation of construction machinery.
Therefore, the application of XCMG hydraulic cylinder repair kit can effectively solve the sealing problem of hydraulic cylinders,
Extend the service life of hydraulic cylinders and improve the efficiency of construction machinery.
