It can disinfect the fumigation channel according to demand and reduce the damage of ozone to circuit components.

[0033] It should be noted that in the design of fumigation channels in the biopharmaceutical field, in order to avoid cross-contamination, different pipelines are usually used to handle air inlet and outlet to ensure the effectiveness and safety of the fumigation process. That is, the fumigation channel is equipped with independent air inlet and outlet channels, and the air inlet valve and exhaust valve can be used to control the opening or closing of the air inlet and outlet channels respectively.

[0034] Specifically, in this embodiment, when fumigation disinfection is required in the fumigation channel, the operator starts the main control cabinet 1 and controls the air inlet valve, the air exhaust valve and the ozone generator 2 through the main control cabinet 1 .

[0035] The main control cabinet 1 can be a fixed main control cabinet 1, for example, the main control cabinet 1 is firmly installed in a fixed position in the equipment or building, so it is not easily affected by external vibration or movement, ensuring the stability of the system operation, facilitating the management personnel to monitor and operate the system, and also facilitating maintenance and servicing.

[0041] Specifically, according to some embodiments of the present invention, the ozone generator 2 includes an ozone generator 2 body and a first base, the ozone generator 2 body is arranged on the first base, and a first moving wheel is arranged on the first base. The first base can provide additional support and balance, so that the ozone generator 2 body is more stable when working, and the first moving wheel can easily move the ozone generator 2 body to a desired position. At the same time, the design of the base can ensure that the ozone generator 2 body will not shake or tilt during use, thereby ensuring the stability of the work.

[0042] According to some embodiments of the utility model, the main control cabinet 1 is a mobile main control cabinet 1, which can be moved to the required position at any time to adapt to different workplaces and needs, and this flexibility allows the equipment to be deployed and operated in different environments without fixed installation, saving time and labor costs.

[0043] Specifically, according to some embodiments of the present invention, the main control cabinet 1 includes a main control cabinet 1 body and a second base, the main control cabinet 1 body is arranged on the second base, and the second base is provided with a second moving wheel.

[0045] According to some embodiments of the utility model, the fumigation channel disinfection system further includes an angle adjustment structure, and the gas diffusion structure is arranged on the angle adjustment structure, and the angle adjustment structure is used to adjust the gas outlet angle of the gas diffusion structure. The angle adjustment structure can accurately adjust the gas outlet angle of the gas diffusion structure so that the released disinfecting gas can cover the area that needs to be disinfected, so as to ensure that the disinfecting gas reaches the target area, thereby improving the disinfection effect.

[0046] The following is a specific example of the working principle of the fumigation channel disinfection system provided by the utility model. Please refer to Figure 1 .

[0047] Before disinfecting the fumigation channel, set the fumigation parameters on the main control cabinet 1, and then start the fumigation command. After receiving the fumigation command, the main control cabinet 1 issues three control instructions. The first control instruction transmits the signal to the first air valve actuator 4 and the second air valve actuator 5 respectively installed on the air inlet channel and the air exhaust channel of the fumigation channel through the first remote control transceiver unit 3 set in the main control cabinet 1. The first air valve actuator 4 and the second air valve actuator 5 close the air inlet channel and the air exhaust channel of the fumigation channel according to the control instruction, so as to isolate the fumigation channel from other rooms served by a combined air handling unit, and prevent fresh air from entering the fumigation channel to dilute the ozone concentration and cause the disinfection concentration to be too low; after the above actions are completed, the second control instruction is transmitted through the second remote control transceiver set in the main control cabinet 1. Unit 6 transmits the signal to the mobile ozone generator 2 placed in the fumigation channel, and the mobile ozone generator 2 starts to work, generating a set amount of ozone to disinfect the fumigation channel, and the mobile ozone generator 2 can be moved and placed in a suitable position without affecting the operation of other equipment or the position of personnel operation; the third control command transmits the signal to the exhaust fan 8 set on the exhaust channel through the exhaust fan control unit 7 set in the main control cabinet 1, and controls the exhaust fan 8 to stop, so as to prevent the fumigation channel from replacing air to reduce the ozone concentration and causing too much negative pressure to the room to damage the sealing of the room. After the ozone is disinfected in the fumigation channel for a set time, it automatically switches to the normal operation mode, opens the air supply valve, exhaust valve and exhaust fan 8, replaces the ozone in the fumigation channel, and discharges it to the outside until there is no ozone smell in the fumigation channel, and personnel can enter to take out the disinfected items. The whole process completes the fumigation without affecting the operation of the system.

[0048] It can be seen from the description of the above embodiments that the fumigation channel disinfection system provided by the utility model has at least the following advantages:

[0049] By setting up a main control cabinet 1, an air inlet valve, an air exhaust valve and an ozone generator 2, during disinfection, the main control cabinet 1 controls the air inlet valve and the air exhaust valve to close the air inlet and air outlet of the fumigation channel, so that the fumigation channel is isolated from other rooms served by a combined air handling unit, and the ozone generator 2 is controlled to discharge ozone in the fumigation channel for disinfection, so that the fumigation channel can be disinfected independently to prevent ozone from entering other rooms served by a combined air handling unit and affecting personnel and equipment. The fumigation channel disinfection system provided by the utility model is used to solve the defects of the existing fumigation mode that disinfection is restricted by working time and is easy to cause damage to circuit components. It can disinfect the fumigation channel according to needs and reduce the damage of ozone to circuit components;

[0050] By making the main control cabinet 1 and the ozone generator 2 mobile, it is convenient to move and carry, thereby improving the flexibility of the system;

[0051] The system control logic is simple, the stability is strong and the cost is low.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it.
