The vertical steam sterilizer capable of recovering waste heat further includes: a conveying device 2, which is arranged inside the box body 1; a placing device 3, which is arranged inside the box body 1; an energy-saving device 4, which is installed below the box body 1; a pressure relief device 5, which is installed above one side of the box body 1; wherein, the conveying device 2 can convey steam into the box body 1, and at this time, the articles placed above the placing device 3 can be sterilized. The energy-saving device 4 can realize the waste heat recovery work of the steam, and the pressure relief device 5 can automatically perform the pressure relief protection work;
[0024] In the specific implementation process, it is particularly worth noting that the pressure gauge 7 can display the pressure inside the box body 1 in real time. The conveying device 2 can convey the external steam into the box body 1, and then the articles placed above the placing device 3 can be sterilized. The energy-saving device 4 can recover the steam discharged through the pressure relief device 5 for the reuse of heat;
[0025] Specifically, when using this vertical steam sterilizer capable of recovering waste heat, first, the staff opens the box body 1, then places the articles to be sterilized above the placing device 3, and then closes the box body 1. At this time, the staff conveys the steam into the box body 1 through the conveying device 2, and at this time, the articles placed above the placing device 3 can be sterilized. When the pressure inside the box body 1 is too high, the pressure relief can be automatically performed through the pressure relief device 5, and then it is conveyed into the water source inside the box body 1 through the energy-saving device 4, so as to perform the waste heat recovery work.

[0027] In the specific implementation process, it is particularly worth noting that the steam inlet pipe 201 can convey external steam into the interior of the spray pipe 202 and then spray it into the interior of the box body 1 through the spray heads 203, and at this time, the sterilization work of the articles can be carried out.
[0028] Specifically, on the basis of the above-mentioned first embodiment, during sterilization, the staff connects the steam inlet pipe 201 to an external steam supply device. At this time, external steam can be conveyed through the spray pipe 202 and then sprayed into the interior of the box body 1 through the spray heads 203, and at this time, the sterilization work of the articles can be carried out.

[0036] In the specific implementation process, it is particularly worth noting that the staff can supplement and discharge water sources through the second conduit 403, and the first conduit 401 can conduct steam to the lower part inside the box body 1;
[0037] Specifically, based on the above-mentioned Embodiment 1, Embodiment 2, Embodiment 3 and Embodiment 4, when recovering waste heat, the steam during pressure relief can be conveyed through the first conduit 401 to the lower part inside the box body 1.
