[0002] Hydrogen peroxide disinfection technology is widely used in biological laboratories, clean rooms of pharmaceutical factories and hospitals, and is used for large space disinfection, has good effect and no residue after disinfection. The hydrogen peroxide disinfection process mainly includes three processes: adjustment stage, maintenance stage and degradation stage. The adjustment stage is to quickly fill the hydrogen peroxide vapor into the space to reach a certain concentration range; the maintenance stage is to maintain the hydrogen peroxide concentration in the space for a period of time to ensure the killing effect of hydrogen peroxide vapor on pollutants; the degradation stage is to catalytically decompose the hydrogen peroxide vapor, and the products of catalytic decomposition are generally water and oxygen. When the hydrogen peroxide concentration is reduced to a safe value (generally below 1 ppm), personnel can enter the disinfection room.
[0003] When the hydrogen peroxide vapor is delivered to the space in the form of large flow, if it cannot be effectively diffused, it will gather near the disinfection machine. Too much vapor gathered together is easy to condense, and condensation will cause two adverse consequences: one is to bring the risk of oxidation corrosion of objects in the room, and the other is to cause invalid waste of disinfection solution.
[0004] At the same time, due to the narrow corridor of the clean room, if the disinfection machine is arranged on the corridor, a large amount of gas output by the disinfection machine will collide with the corridor wall, which will have the risk of condensation. INVENTION CONTENTS

[0027] As Figures 1-8 The utility model provides a kind of hydrogen peroxide vaporization disinfection machine, including fuselage 1, air inlet 2 being located at the bottom of fuselage 1, diffusion assembly 3 being located at the top of fuselage 1, hydrogen peroxide cabin being located between air inlet 2 and diffusion assembly 3, the diffusion assembly 3 is peripherally spaced and arranged with several gas conveying pipes 31, and two opposite gas conveying pipes 31 are provided with opening and closing control member 32, so that opening and closing control member 32 blocks gas conveying pipe 31 to exhaust, and the two sides of fuselage 1 pause exhaust.
[0028] The outside air is sucked into the machine body through the bottom air inlet, and then the hydrogen peroxide gas in the hydrogen peroxide cabin is discharged outward, so that the hydrogen peroxide gas uniformly diffuses in different directions along the gas pipes, improves the spatial diffusion uniformity of the hydrogen peroxide gas, avoids the condensation of too much hydrogen peroxide gas on the same side, and at the same time, when the disinfection machine is placed in a long and narrow structure disinfection space, the two gas pipes with opening and closing control members arranged opposite to each other are placed towards the two side walls, and the two gas pipes arranged opposite to each other are blocked and discharged by the opening and closing control members, so that the two sides of the machine body towards the wall direction will not be discharged with hydrogen peroxide, thereby avoiding the condensation caused by the contact of a large amount of hydrogen peroxide gas with the two side walls.
[0029] The hydrogen peroxide cabin evaporates the hydrogen peroxide liquid into hydrogen peroxide gas, so that the hydrogen peroxide gas is discharged from the gas pipe to the disinfection space.
[0030] In an embodiment of the present scheme, the opening and closing control member adopts a solenoid valve, which controls the on-off state of the pipeline of the gas pipe.
[0031] It is worth mentioning that the air inlet of the present scheme is also provided with a power fan, so that the air is transported from bottom to top by the power fan at the bottom of the disinfection machine, and the air flow at the bottom is low in concentration, while the diffusion assembly transports high-concentration hydrogen peroxide gas, thereby achieving the effect of internal circulation. When the concentration outside the disinfection machine gradually increases, the high-concentration hydrogen peroxide gas will flow from the bottom to the top of the disinfection machine, thereby improving the disinfection effect inside the disinfection machine and eliminating the hidden danger of polluting the external environment after disinfection.
[0032] Preferably, the first power fan 33 is connected to one side of the gas pipe 31 to drive the gas to be discharged from the gas pipe 31.
[0033] Specifically, the gas in the hydrogen peroxide cabin is sucked into the gas pipe by the first power fan, and the plurality of gas pipes synchronously discharge gas in different directions, thereby improving the uniformity of hydrogen peroxide gas discharge.
[0034] Preferably, the machine body 1 is provided with a decomposition module 4, the decomposition module 4 comprises an air pipe 41, a second power fan 42 arranged at one end of the air pipe 41, and a catalyst 43 arranged at the other end of the air pipe 41, so that the air enters the air pipe 41 from the catalyst 43 and is discharged outward from the second power fan 42.
[0035] Specifically, after the hydrogen peroxide gas disinfects the space for a certain period of time, the degradation phase is needed, at which time the hydrogen peroxide gas in the space needs to be catalytically decomposed, so that the outside air is sucked into the air pipe through the second power fan, and the air is catalytically degraded by the catalyst to ensure the stable degradation of the hydrogen peroxide gas in the space, and the air can also be preliminarily filtered by the catalyst to prevent particulate matter in the space from entering the second power fan and causing damage to the fan.
[0036] The catalyst 43 includes one or more of platinum, palladium, and rhodium.
[0037] Preferably, the air pipe 41 has an L-shaped structure, so that the two ends of the air pipe 41 are respectively installed at two adjacent side positions of the fuselage 1.
[0038] Specifically, due to the L-shaped structure of the air pipe, the two ends of the air pipe can be directly connected to the two adjacent side positions of the fuselage, which has the advantage that the air pipe does not need to pass through most of the space inside the fuselage, so that the air pipe bypasses the remaining cabins such as the hydrogen peroxide cabin inside the fuselage, thereby facilitating the maintenance of the decomposition module.
[0039] Preferably, the two ends of the air pipe 41 are connected to the fuselage 1 through mounting brackets 44.
[0040] Specifically, the mounting bracket improves the stability of the connection of the air pipe, and also makes the air pipe more convenient to disassemble and maintain.
[0041] The mounting bracket and the fuselage are connected by bolts or other connecting members.
[0042] Preferably, the diffusion assembly 3 further comprises a one-to-many adapter 34 in communication with the plurality of gas conveying pipes 31, so that the gas in the hydrogen peroxide cabin is divided into multiple paths of gas by the one-to-many adapter 34 and discharged outward.
[0043] Specifically, after the hydrogen peroxide gas is discharged from the hydrogen peroxide cabin, it is divided into multiple paths of gas by the one-to-many adapter to ensure that the hydrogen peroxide gas is stably and uniformly discharged outward through each gas conveying pipe.
[0044] Preferably, the fuselage 1 is provided with a decomposition air inlet 5 and a decomposition air outlet 6 on the side, and the decomposition air inlet 5 is arranged corresponding to the catalyst 43, and the decomposition air outlet 6 is arranged corresponding to the second power fan 42, so that the catalyst has a stable air inlet, and the second power fan can stably discharge air, to ensure the stability of the degradation phase.
[0045] The utility model is not limited to the above best implementation, and any person can draw other various forms of products under the enlightenment of the utility model, but no matter any change in its shape or structure, all the technical schemes with same or similar to the application fall in the protection scope of the utility model.
