      The 2022 Geneva International Exhibition of Inventions, jointly organized by the World Intellectual Property Organization and the Swiss Federal Government, will be held online in March
    .
    About 800 innovation and technology inventions from 25 countries and regions participated in the exhibition.
    After being reviewed by an international professional jury, the review results were announced on March 28.
    A batch of new technologies and new inventions in the chemical industry won the gold medal at this Geneva International Invention Exhibition.
    and Silver Award

    .

      The project "Solid Waste Coke-Free Gasification Technology" completed by the team of Associate Professor Zhao Ming from the School of Environment, Tsinghua University won the Gold Award
    .
    The project is applied to the organic solid waste tar-free gasification device - Yunqing Furnace.
    Through the unique multi-stage air supply double oxide layer structure, the problem of gasification tar is solved in principle, and the gasification efficiency and combustible gas cleanliness are improved.

    .
    The carbon content of the bottom ash is reduced to less than 3%, and the effect of reducing the amount of resources is obvious

    .
    The system is equipped with multi-point parameters and integrated automatic control system, which has higher stability and safety.
    Gas products can also be used for multiple transformations such as heat, electricity and chemical

    .
    The gold medal was also awarded to the project "A Negative Air Ion Generator with High-Pressure Airflow Carrying Water Molecules Impacting the Collision Surface" led by Professor Lin Jinming from the Department of Chemistry of Tsinghua University

    .
    This project simulates the principle of waterfalls in nature, and generates negative air ions through the collision of water vapor on the solid interface.
    While ensuring the production and release of a large number of negative ions, the production of harmful by-products such as ozone and nitrogen oxides is avoided

    .

      The project "Submicron Intelligent Vibration Control System for High-grade Grinders" completed by Associate Professor Pan Xin from the School of Mechanical and Electrical Engineering of Beijing University of Chemical Technology also won the gold award
    .
    Aiming at the problem of "inaccurate and fast grinding" of the machine tool due to uneven wear of the grinding wheel during the operation of the high-end grinding machine, a new electromagnetic intelligent vibration control system that can compensate for the unbalance of the grinding wheel in real time is proposed, and radial excitation is invented.
    The integrated electromagnetic balance actuator structure improves product stability and drive efficiency

    .
    Drawing on the principle of "molecular targeted therapy" in medical science, the research team has formed a rotor vibration targeted suppression method, realizing the sub-micron high-precision vibration suppression of the grinding wheel-rotor system

    .
    The system has achieved practical engineering application in high-end grinding machines such as cylindrical grinders and bearing grinders

    .

      The gold medal was also awarded to the project "A Double Halbach Array Spherical Lorentz Force Magnetic Bearing" completed by the team of Professor Liu Qiang from the School of Mechanical Engineering of Beijing Institute of Petrochemical Technology
    .
    In this project, the channel decoupling and the multi-objective optimization design method based on the magnetic field coupling factor are proposed for the first time, which essentially eliminates the coupling disturbance between translation and deflection, improves the uniformity of the air gap magnetic density by two orders of magnitude, and makes the suspension mover The motion positioning accuracy has been improved from micron level to nanometer level, and two types of high-precision spherical decoupling magnetic bearings have been invented

    .
    Relevant achievements are directly applied to China's first maglev control sensitive gyro prototype, Micro/Mini LED new generation display chip manufacturing, maglev RGV track car intelligent transmission system,

    etc.

      The "Integrated Energy System Design and Optimization Operation Technology Platform" project jointly declared by State Grid Shandong Comprehensive Energy Company and Shandong University won the Silver Award
    .
    This project is aimed at the problems of various equipment types and complex structures in the design process of integrated energy systems, large differences in cooling, heating and power loads in different application scenarios and environments, strong inherent volatility and uncertainty of new energy, and changing system operation modes.
    A planning and design method integrating load forecasting, system structure, equipment capacity and operation mode is provided, and the optimal operation of the integrated energy system is realized

    .
    The project has the functions of realizing the optimal structure of the design system, the optimal type of equipment and capacity configuration under different application scenarios and different optimization objectives, and also has functions such as real-time load monitoring, switching analysis of system operation modes, and real-time optimization of equipment operation.

    .

      The project "Preparation of Agricultural Straw Adsorption and Separation Functional Composite Materials" jointly developed by Guizhou Merit Environmental Protection Technology Co.
    , Ltd.
    and Guizhou Normal University Geoenvironment College also won the silver award

    .
    There are more than 900 million tons of agricultural straw waste in China every year, and the comprehensive utilization rate is low.
    Incineration will cause environmental pollution and a large amount of carbon dioxide emissions

    .
    The scientific research team adopts the idea of ​​"waste" and "waste", and conceives of using waste straw to solve the problem of environmental pollution, using agricultural straw waste as raw material to prepare plant fiber, and at the same time compounding with the polysaccharide extracted from the waste to prepare adsorption separation function Filter material for environmental pollution control

      As one of the world's most prestigious innovation and technology exhibitions, the Geneva International Exhibition of Inventions is a global annual event for innovative inventions
    .
    The Geneva International Invention Exhibition is one of the three major invention exhibitions in the world (Geneva Invention Exhibition, Pittsburgh Invention Exhibition, Nuremberg Invention Exhibition).
    It was founded in 1973 and has been successfully held for 49 sessions so far

    .

      The exhibition is jointly organized by the Swiss Federal Government, the Geneva Cantonal Government, the Geneva Municipal Government, and the World Intellectual Property Organization.
    It is also one of the longest and largest invention exhibitions in the world

    .
    Entries must have independent intellectual property rights and have completed the research and development of prototypes or finished products

    .

      This year's Invention Exhibition attracted about 800 scientific and technological achievements from well-known universities, scientific research institutions and enterprises from 25 countries and regions including China, the United States, and Germany
    .
    In addition, the world's top 500 companies and multinational intellectual property institutions have gathered online to seek further cooperation in patents and industries
