Tong Tong: This is indeed a prominent issue in the drying of materials. In the dynamic vertical dryer, we use the anti-blocking vibration distribution device, vibration flow adjustment and blocking prevention device to solve the problem of blocking materials. These several technologies have applied for national patents. The use of these devices will effectively solve the phenomenon that the particle size becomes larger and clogging the boring due to the material sticking in the drying process, which not only completely solves the problem of blocking materials, but also improves the heat exchange efficiency by more than 40%, ensuring the use of the device. High drying output and low coal consumption.
Reporter: As far as I know, this is the first time that an automatic microcomputer detection control system has been used in the drying system. I do not know what measures Cobolt has taken to ensure its implementation.
Tong Zong: The cooperation with us was organized by Prof. Tang Wencheng, the task team of the Department of Mechanical Engineering of Southeast University. The task force has successively undertaken a number of national 863 projects, the National Natural Science Fund project, and corporate science and technology research projects. Responsible for the digital model design of the drying system in the project, through the theoretical analysis and on-site data acquisition and processing, optimize the process parameters, and provide an accurate solution for key technologies such as establishing the parameter optimization model for the drying system control software.
Reporter: What are the main technical, economic, and socio-economic benefits of the KBDH dynamic vertical dryer?
Tong Tong: Dynamic vertical dryer system has low coal consumption and high drying output. Taking rotary drying as an example, in the same drying production, the coal consumption of the dynamic vertical dryer is about 40% of the coal consumption of the rotary dryer, the power consumption is about 50%, and the thermal efficiency is as high as 95%. The equipment can also use the waste heat from the rotary kiln as the heat source to dry the material, which has extremely profound significance and necessity for saving energy and reducing energy consumption.
Reporter: After listening to your introduction, we are very concerned about the development of the KBDH dynamic vertical dryer developed by your company. Do you not know when RBDH Dynamic Vertical Dryer can be brought to market?
Tong Tong: The new type of KBDH dynamic vertical dryer and airbag pulse bag filter and automatic computer detection control system are our cooperation projects with Southeast University. In 2005, we invested 6 million yuan for experiments. Room test, prototype preparation test, purchase of production equipment, etc. At present, the project has applied for two invention patents and six utility model patents that have been fully introduced to the market. Due to the advanced nature and applicability of this energy-saving equipment, it can also be applied to materials drying in industries such as environmental protection, chemical engineering, and iron and steel, in addition to the building materials industry. China's current power shortage, resources are scarce, KBDH dynamic vertical dryer has a positive role in advancing the technological progress of the high-energy-consuming cement industry, and it is also of great significance to improve the market competitiveness of enterprises.
