▎ 摘　　要

NOVELTY - The device has an airflow inlet (26) that is connected to a coarse filter screen (1). An air extractor (2) is connected with an air chamber (25), and the air chamber is connected with first flow channel (23) and second flow channel (24). First port (10) of the first flow channel and second port (17) of the second flow channel communicate with first waste heat recovery zone (8) and second waste heat recovery zone (27), and a microwave treatment zone (20) is set between the first waste heat recovery zone and the second waste heat recovery zone. The microwave treatment zone is equipped with a microwave generating device, and a gas reversing system is set in the air chamber for controlling of the first flow channel and the second flow channel, and an air outlet (21) communicates with an upper portion of the air chamber. USE - Air sterilizing and disinfecting device based on microwave radiation coupling foam ceramic adsorbent material. ADVANTAGE - The device can effectively and quickly kill the virus and pathogen transmitted by air under the condition of low pressure drop and low energy consumption. The introduction of the waste heat recycling mechanism and the humidity control mechanism can further reduce the energy consumption and improve the sterilizing effect. By combining with the air flow switching device, it can realize not changing the system inlet and outlet air flow direction, fully using the processed gas waste heat, so as to reduce the average temperature rise of air flow in whole system, further reducing energy consumption of the system. The air humidity adjusting system controls the humidity of to-be-processed air flow. It can obviously improve the adsorption capacity of virus-containing aerosol and effectiveness of system to kill virus. The foam ceramic material such as silicon carbide or zirconium oxide has high specific surface area. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an air sterilizing and disinfecting method based on microwave radiation coupling foam ceramic adsorbent material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of an air sterilizing and disinfecting device. 1Coarse filter screen 2Air extractor 3Humidity adjustor 4Humidity controller 5First plunger valve 6Second plunger valve 7Plunger valve electric control device 8First waste heat recovery zone 9First thermocouple 10First port 11Second thermocouple 12Mica sheet 13Control system 14Magnetron 15Guided wave tube 16Metal net 17Second port 18Fourth thermocouple 19Third thermocouple 20Microwave treatment zone 21Airflow outlet 22Humidity probe 23First flow channel 24Second flow channel 25Air chamber 26Airflow inlet 27Second waste heat recovery zone
