Record of Development of Energy Conservation and Drying Engineering Research Center of Shandong Academy of Sciences

Drying equipment

The Energy Conservation and Drying Engineering Research Center of the Shandong Academy of Sciences learned that after more than a year of hard work, the center developed a 600,000 tons/year PTA major domestic energy-saving drying equipment, theoretical models, and industrial prototypes have been completed and are currently undergoing demonstration. It will be put into production; the largest gypsum calcining and drying equipment developed by the center in cooperation with Shandong Xinwen Mining Group has been put into production. These scientific research achievements with independent intellectual property rights will break the monopoly of large-scale energy-saving drying equipment manufacturing in foreign countries for a long time.

According to researcher Shi Yongchun, the chief expert of the center, the research and development of the center adopts the model of “research center-incubation model enterprise-service industry”. He believes this is an effective way to accelerate the development and application of domestic equipment. In order to accelerate the industrialization of scientific research results, the center has hatched a science and technology demonstration company, Shandong Tianli Drying Equipment Co., Ltd. as a carrier for the transformation of scientific research achievements. After the center completes technical application research and small-scale and middle-scale tests, Tianli will improve its technological achievements and productize it, and then put it into the application of large-scale enterprises in related industries. After the demonstration of product application, it will be promoted to the entire industry. .

Shi Yongchun said that the center mainly focuses on various major energy-saving drying equipment required by various industries and major dry common technologies faced by various industries, and conducts research on applied basic theories and applied technologies; according to the transformation generation, research generation, pre-research generation Ideas, according to different types of drying technology for original innovation, integrated innovation and the introduction of digestion and absorption and innovation; integration of thermodynamics, heat transfer, fluid mechanics and other disciplines of research theories, to explore the drying process heat and mass transfer law, the establishment of key industries large Drying device and drying process engineering model; developing world-class technical software, ascertaining the drying process, and then developing large-scale drying equipment and advanced drying technology through small-scale test and pilot-scale test. The center's practice has completely freed itself from the passive situation in which domestic large-scale drying plants are now domestically used to simply imitate the road.

The requirements of the Shandong Academy of Sciences for the Center are that the results of the research must be "upright." The so-called "ceiling" refers to the need to focus on key common drying technology issues that are strong in the industry, with a large degree of correlation, and have a prominent role in the development of key technologies and core technologies with independent intellectual property rights, and to achieve breakthroughs in applied basic theoretical research. Drying technology progress in various industries has a major driving role; "site" refers to the research results must be able to promote the application, into a terminal product, generate benefits. The center cooperates with more than a dozen famous universities and scientific research institutes in China to conduct basic research on applied theories, and cooperates with large-scale enterprises in the development of applied technologies. The combination of production, study and research ensures that the research results are "upright."

In addition, the center has established long-term cooperation relationships with internationally renowned drying technology research institutes such as the Belarusian Reckov Heat and Mass Transfer Institute and the Technical University of Lodz, Poland. After hard work, the center has developed 35 scientific research achievements, has undertaken 4 national torch projects, 4 national key new product planning projects, and 3 national key promotion program projects. It has obtained 68 independent intellectual property patents and obtained Shandong Provincial Science and Technology. Progress second prize 3 items.

At present, the large-scale internal thermal fluidization equipment for calcining and drying the soda ash calcined by the company in cooperation with Shandong Haihua Group weighs 180 tons and is 18 meters high. It is the first in the world. After applying 7 sets in Haihua Group, it has successively established Sanyou Base in Tangshan. Industrial Co., Ltd., Henan Anpeng Soda Minerals Co., Ltd., Shandong Haitian Biochemical Co., Ltd. and other 10 national soda ash plants to promote more than 100 sets, at present the product has considerable influence in the soda industry; with PetroChina Liaohua Branch The research and development of adipic acid large-scale fluidization drying technology and equipment, energy efficiency of 75%, energy-saving effect is obvious; with the cooperation of Qingdao Haijing Group developed the largest domestic CPE drying heat exchange device, fluidized bed area of ​​20 square meters, At present, it has been exported to foreign countries. The large-scale flash dryer developed in cooperation with China Aluminum Corporation Shandong Branch has reached the international advanced level. It has applied 12 sets in Shanlu Company, and its energy-saving effect is 20% higher than that of domestic products.

It is reported that up to now, the center has cumulatively researched and developed more than 1,000 sets of drying equipment to serve industrial production, and promoted more than 800 enterprises. The benefits of energy saving and investment saving have exceeded 10 billion yuan.

It is understood that the application of drying technology involves chemical, petrochemical, pharmaceutical, building materials, light industry, feed, food, paper, wood, food and many other industries. The drying process is a domestic high-energy-consuming process. The energy consumed by it accounts for about 12% of the total domestic energy consumption. At the same time, the average energy efficiency of the domestic drying process is only 40% to 50%. The advanced level in foreign countries generally reaches More than 70%. At present, some of the large-scale drying equipment and technologies needed in China are still almost entirely dependent on imports.
