The gas-liquid mixing heater is connected to an air pipe, a hydrogen peroxide pipe and a first output pipe. The first output pipe extends into the spray channel housing and is connected to each of the hydrogen peroxide nozzles to deliver the vaporized hydrogen peroxide to each of the hydrogen peroxide nozzles.

4. The cover sterilization system as described in claim 3, characterized in that, A concentration sensor and a first temperature sensor are provided on the first output pipeline, a second temperature sensor is provided inside the spray channel housing, and a third temperature sensor is provided inside the drying channel housing.

5. The cap sterilization system as described in claim 1, characterized in that, An air heater is also provided outside the drying channel housing. An air filter and a second output pipe are connected to the air heater. The second output pipe extends into the drying channel housing and is connected to each of the air nozzles to deliver hot sterile air to each of the air nozzles.

6. The cap sterilization system as described in claim 1, characterized in that, The top of the spray channel housing is also connected to a first exhaust fan via a first exhaust duct, and a filter is provided at the air outlet of the first exhaust fan; the top of the drying channel housing is also connected to a second exhaust fan via a second exhaust duct.

7. The cap sterilization system as described in claim 1, characterized in that, The outer walls of the spray channel housing, the outer walls of the holding channel housing, and the outer walls of the drying channel housing are all covered with a heat insulation layer containing an internal heating device.

8. The cap sterilization system as described in claim 1, characterized in that, The cover sterilization system includes a rectangular sealing shell extending along the cover conveying direction. A first partition plate and a second partition plate are provided inside the rectangular sealing shell to divide the rectangular sealing shell into the spray channel shell, the holding channel shell and the drying channel shell. Through holes are provided on the first partition plate and the second partition plate, and the conveying guide rail can pass through the through holes and can be connected to the first partition plate and the second partition plate.

9. The cap sterilization system as described in claim 1, characterized in that, Multiple electrostatic precipitators are provided at intervals along the conveying direction inside the dust removal channel housing and below the conveying guide rail. The dust removal exhaust port of each electrostatic precipitator is connected to the air inlet of a third exhaust fan outside the dust removal channel housing through a dust suction pipe.
