On January 25, 2018, the third-party professional scientific and technological achievements appraisal agency - China Science and Technology (Beijing) Science and Technology Achievements Evaluation Center in Beijing according to the relevant provisions of the "Scientific and Technological Evaluation Methods" of the Ministry of Science and Technology, according to the standards and procedures for scientific and technological achievements evaluation In accordance with the principles of science, independence, objectivity, and impartiality, we organized experts to jointly implement energy-saving precious wood heat pumps, such as the Institute of Physical and Chemical Technology of the Chinese Academy of Sciences, the Productivity Promotion Center of Dayong Town, Zhongshan City and Henan Hengheng Energy Saving Technology Co., Ltd. The Drying Technology project evaluated the scientific and technological achievements.
It is reported that the experts of the evaluation meeting were professors from Beijing Forestry University and Zhang Shuangbao, a professor at Beijing University, a professor at Peking University, and Liu Moubin, a researcher at the Institute of Acoustics at the Chinese Academy of Sciences, and Li Junbao from the Institute of Acoustics, Chinese Academy of Sciences. Zhang Dahong, researcher of the Institute of Wood Industry, Chinese Academy of Forestry, Zhou Yongdong, Ph.D., researcher of the International Bamboo and Rattan Center, and Wang Ge, the director of the National Timber Standardization Technical Committee, and Zhou Haibin, associate researcher.
After expert review, the project considered that precious wood such as mahogany was the main research object, and research on the key technology of heat pump energy saving was carried out. The precious wood heat pump drying process such as mahogany and heat pump drying system with phase change heat storage and waste heat recovery were developed. The main achievements and innovations of the project are as follows: Innovation proposes a technology for dehumidifying the main unit of a closed single evaporator, and constructs a new type of closed wood heat pump drying system; it can be used in environments where the ambient temperature is not lower than -25°C. The waste heat discharged from the kiln reduces the energy consumption of the drying system and enables the efficient use of energy. Based on the drying characteristics of the wood, a heat pump drying control system suitable for the process of drying precious wood such as mahogany is developed. The project applied for 6 national patents, including 5 invention patents, 2 authorizations, and 1 utility model patent. The technical demonstration and application show that the average COP of the heat pump system is more than 3, and the operating power consumption is only 1/3 of the electric heating system; compared with the conventional drying, the energy consumption of the heat pump drying equipment is reduced by more than 30%; the precious wood such as mahogany is dried The qualified product rate is higher than the coal-fired drying kiln, and there is no direct CO2 emission, and the energy-saving emission reduction effect and economic benefit are significant. The results have reached the international advanced level of similar technologies. After a thorough review by the expert group, the participating experts unanimously agreed that the "Redwood and other precious wood heat pump energy-saving drying technology" project passed the evaluation of scientific and technological achievements.
