The hydrogen peroxide solution is pumped into the hydrogen peroxide generator 8 by the peristaltic pump 10, and the vaporized hydrogen peroxide passes through the circulation pipeline 5, enters the experimental cabin cavity 2 from the air inlet 3 for sterilization, and then enters the circulation pipeline 5 through the exhaust port 4, passes through the first valve 6 to the internal circulation fan 7 to complete the circulation.

[0032] The utility model adopts a flash evaporation hydrogen peroxide generator 8 to sterilize the experimental chamber cavity 2, which includes a plurality of heating rods 14, an evaporation plate 15 is arranged above the heating rods, a mesh plate 16 is arranged above the evaporation plate 15, and the heating rods 14, the evaporation plate 15 and the mesh plate 16 are all arranged in an insulation box 17. The hydrogen peroxide pipeline 9 passes through the insulation box 17 and the mesh plate 16 is arranged above the evaporation plate 15 in sequence. The heating rod 14 is used to heat the evaporation plate 15, and the hydrogen peroxide evaporates in the evaporation plate 15 and is dispersed into the circulation pipeline 5 by the mesh plate 16. The hydrogen peroxide generator of the utility model can also be added with a cold evaporation hydrogen peroxide generator 8 according to the experimental needs, so that the utility model can include all hydrogen peroxide sterilization methods (cold evaporation, flash evaporation) on the market.

[0033] The circulation pipeline 5 is connected to the dehumidification pipeline 12 and the hydrogen peroxide degradation pipeline 13, and the dehumidification pipeline 12 and the hydrogen peroxide degradation pipeline 13 are both connected in parallel with the circulation pipeline 5 where the first valve 6 is located. The dehumidification pipeline 12 is provided with a desiccant device 18 and a second valve 19, and the desiccant device 18 includes a desiccant box and a desiccant arranged inside the desiccant box, which is used to dry the hydrogen peroxide gas passing through the dehumidification pipeline 12. The humidity can be adjusted, that is, a high humidity environment can be created, and a dry environment can also be created.

[0034] The hydrogen peroxide degradation pipeline 13 is provided with a manganese dioxide filter 20 capable of decomposing hydrogen peroxide and a third valve 21. After the experiment is completed, the residual hydrogen peroxide in the experimental chamber cavity 2 can be discharged by switching the valve.

[0035] Further, the experimental chamber cavity 2 is provided with at least one visual window 22. The visual window 22 of the utility model is glass.

The housing 1 is provided with an inspection door 29 for inspecting various equipment components inside the housing 1 .

[0036] When the utility model is used, the plate is placed in the experimental cabin cavity 1, and the utility model is connected to the external electrical box and powered on. The internal circulation fan 7 is started, and the first valve 6 is opened. When the sterilization stage begins, the circulating air enters the experimental cabin cavity 2 through the internal circulation fan 7, and then flows back to the internal circulation fan 7 through the first valve 6. The peristaltic pump 10 pumps the hydrogen peroxide solution in the hydrogen peroxide bottle 11 into the hydrogen peroxide generator 8, and the internal circulation fan 7 brings the vaporized hydrogen peroxide in the hydrogen peroxide generator 8 into the experimental cabin cavity 2. The vaporized hydrogen peroxide enters the inside of the circulation pipeline 5 through the experimental cabin cavity 2, and reaches the internal circulation fan 7 through the first valve 6. If the temperature and humidity sensor 27 senses that the humidity in the experimental cabin cavity 2 is too high, the second valve 19 is started and the first valve 6 is closed. The vaporized hydrogen peroxide enters the inside of the circulation pipeline 5 through the experimental cabin cavity 2, reaches the desiccant device 18 through the second valve 19 and directly reaches the internal circulation fan 7, so as to reduce the humidity in the experimental cabin cavity 2.

[0037] At the beginning of the residual discharge stage, the peristaltic pump 10 reverses to return the hydrogen peroxide to the hydrogen peroxide bottle 11, the second valve 19 is opened, the third valve 21 is opened, and the first valve 6 is closed. The hydrogen peroxide gas in the experimental chamber cavity 2 enters the desiccant device 18 and the manganese dioxide filter 20 through the second valve 19 and the third valve 21 at the same time, and then the gas decomposed by the manganese dioxide filter 20 and the hydrogen peroxide gas dried by the desiccant are blown back into the experimental chamber cavity 2 through the internal circulation fan 7. The vaporized hydrogen peroxide is degraded by multiple internal circulations until the concentration sensor 28 senses that the hydrogen peroxide concentration in the experimental chamber cavity 2 drops below 1ppm.

[0038] The size of the experimental chamber cavity 2 of the utility model can be customized, and hydrogen peroxide corrosion resistance test can be performed on materials of different types and sizes. By simulating a variety of experimental conditions, a series of research work on the corrosion of the plate in the experimental chamber cavity 2 is realized, saving a lot of valuable time and money. The utility model can be equipped with two hydrogen peroxide generators 8 (cold evaporation / flash evaporation), covering all hydrogen peroxide sterilization methods currently on the market; the equipped desiccant device 18 can realize humidity adjustment, that is, create high humidity, and can also create a dry environment; the equipped concentration sensor 28, temperature and humidity sensor 27 and operation display screen 26 can realize real-time observation and data recording during the experiment; the equipped internal circulation fan 7 can simulate the turbulence device in the actual sterilization process; the equipped manganese dioxide filter can realize the exhaust of hydrogen peroxide in the experimental chamber cavity 2 through the switching of the valve after the experiment is completed, which is operator-friendly.
