Energy-saving drying engineering technology has achieved a major breakthrough

China's energy-saving drying engineering technology has achieved major breakthroughs. The annual production capacity of 600,000 tons of refined terephthalic acid (PTA) drying domestically produced equipment developed by the Energy Conservation and Drying Engineering Research Center of the Shandong Academy of Sciences has been completed. Theoretical models and industrial prototypes have been completed. This equipment not only compares with foreign products on the technical level, but also improves energy efficiency from the previous 40% to 50% to 70%. After large-scale application of the equipment, it will break the long-term monopoly of foreign companies on large-scale energy-saving drying equipment.

According to researcher Shi Yongchun, the chief expert of the center, the equipment is 4.2 meters in diameter and 42.5 meters in length, and is now undergoing field demonstration in Yangzi Petrochemical. Next, there will be more than 20 sets of PTA-made drying equipment in the country.

In addition to the PTA drying field, the Energy Saving Drying Equipment Engineering Technology Research Center has also established achievements in the drying of many chemical products such as soda ash and adipic acid. The sodium carbonate calcining drying large-scale internal-heating fluidization 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, and has been applied in China after being applied to 7 sets of Haihua Group. Multiple sets, instead of imported equipment. They cooperated with PetroChina Liaohua Branch to develop large-scale adipic acid fluid drying and complete sets of technologies and equipment with an energy efficiency of 75%. Currently, they are being built by Shandong Hongye Group, Shandong Haili Company and Xinjiang Tianli Group.

It is understood that the Energy Conservation and Drying Engineering Research Center of the Shandong Academy of Sciences is an open platform in which the project is a link and closely cooperates with enterprises and universities. At present, the center has researched and developed more than 1,000 sets of drying technologies and equipments to serve industrial production. Its benefits in energy saving and investment saving have reached 10 billion yuan, and more than 800 enterprises have been promoted.

Energy-saving dryer engineering technology is a key core technology widely used in many industries, directly affecting the company's production capacity and energy consumption. According to statistics, the energy consumption of drying equipment accounts for 12% of the total energy consumption of domestic GDP, which is of great significance for the realization of China's energy saving goals. In today's energy shortage, the drying industry is an industry with great potential for energy conservation. At present, the energy efficiency of domestic dry technology is only 40% to 50%, while in foreign countries it is as high as 70%.
