10. A method for treating waste gas from high-temperature sterilization of medical waste based on a diamond film, comprising the system for treating waste gas from high-temperature sterilization of medical waste based on a diamond film according to any one of claims 1 to 9, characterized in that: The specific steps are as follows: S1. High-temperature disinfection waste gas is introduced into the interior of the metal filter cartridge (120b) through the first air inlet pipe (120b-1), and the driving member (130) is started to drive the metal filter cartridge (120b) and the ceramic fiber filter cartridge (120c) to rotate coaxially at a differential speed through the planetary gear set (120a), thereby performing gradient separation on particles in the waste gas according to particle size. The screened waste gas enters the first air outlet pipe (110a) and is then discharged into the second reaction box (210). At the same time, the phase change material layer (140) recovers the residual heat of the waste gas in the first air outlet pipe (110a); S2. When the planetary gear set (120a) rotates, the diamond catalytic bed (220) is driven to rotate via the transmission assembly (230), thereby performing an efficient catalytic oxidation reaction on the exhaust gas entering the second reaction box (210), thereby decomposing and absorbing volatile organic compounds in the exhaust gas. At the same time, the water vapor generated by the steam generating assembly (140a) on the side wall of the phase change material layer (140) is passed to the diamond catalytic bed (220), maintaining the humidity of the diamond catalytic bed (220), thereby preventing the catalyst from being sintered and deactivated at high temperature. At the same time, water molecules participate in the decomposition reaction of the volatile organic compounds. S3. The waste gas discharged from the second reaction box (210) enters the spiral gradient condenser tube (310a) for gradient condensation and cooling, thereby forming a temperature difference. At this time, the thermoelectric power generation plate (310b) recovers the ambient temperature difference energy of the tube wall to generate electricity, thereby converting thermal energy into electrical energy. When the diamond catalytic bed (220) rotates, it drives the inertia flywheel (320) to store energy. When the equipment is shut down, the inertia flywheel (320) maintains the continuous operation of key components for a period of time through its own inertia, thereby reducing the impact on the power grid during the start-up and shutdown process of the equipment, and thus feeding energy back to the equipment.
