[0035] A steam pipe 325 is provided in the disinfection chamber 32, and a plurality of steam outlets are provided on the steam pipe 325. A rotating filter cartridge 326 is provided in the disinfection chamber 32, and a gear ring is provided on the outer side of the rotating filter cartridge 326.

[0036] The specific usage process is as follows:

[0037] The control device 1 starts the heat collection circulation oil pump 212 to circulate the low-temperature heat transfer oil to the trough collector 211 to absorb heat energy. The heated high-temperature heat transfer oil returns to the heat preservation oil tank 23, and the cycle repeats until the oil storage temperature sensor 232 detects that the temperature reaches the set value. The oil storage temperature sensor 213 is used to detect the outlet oil temperature. When the temperature value is lower than the set value, the electric heater 231 is started for supplementary heating. When the solar energy storage mechanism 22 has sufficient power generation, the solar energy storage mechanism 22 supplies part of the electric energy to the equipment through the distribution cabinet 224 through the inverter 222, and stores part of the electric energy in the energy storage battery 223. In continuous rainy weather, the distribution cabinet 224 is powered by the energy storage battery 223 and the inverter 222, and the distribution cabinet 224 outputs AC power to meet the power needs of various equipment in the system.

[0038] When medical waste needs to be disinfected, after a whole package of medical waste is put into the feeding channel 322 and the sealing cover 321 is closed, the control device 1 starts the exothermic circulation oil pump 26 and opens the oil outlet control valve 27, so that the steam generator 31 generates high-temperature steam to disinfect the material in the disinfection chamber 32, and at the same time starts the drive motor 328 to stir the material.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
