Efficient in-situ online disinfection of exhaust outlets should be carried out under the guidance of

Efficient in-situ online disinfection of exhaust outlets should be carried out under the guidance of professional personnel. Firstly, the biological sealing valve should be closed to block the gas in the box from the outside world,

After connecting the corresponding interface, personnel leave and perform online disinfection through remote control, releasing gas disinfectant during this process

There are formaldehyde, gaseous chlorine dioxide, vaporized hydrogen peroxide (VHP), etc. Wait for the gas disinfectant to stay in the box for a sufficient amount of time before thoroughly cleaning the exhaust outlet

The gas disinfectant generator can only be turned off after bottom disinfection. During this process, personnel are not allowed to enter the laboratory to prevent contamination. Disinfection process completed

Afterwards, the laboratory needs to be activated.

The ventilation system emits gas disinfectants that meet environmental requirements. Only when the concentration of gas disinfectants indoors reaches a safe level can personnel enter the room

Internally, turn off the gas circulation disinfection device and remove the biological indicator to determine if the disinfection effect meets the requirements. Efficient exhaust outlet used in biosafety laboratory

The exhaust section.

The in-situ leak detection design of the high-efficiency exhaust outlet adopts scanning leak detection technology to perform in-situ leak detection on the high-efficiency filter. Near the high-efficiency filter

Install a wired scanning leak detection sampling device at the position of the air outlet surface. The sampling probe is the same width as the air outlet surface of the filter, and the sampling port is a narrow slit in a linear shape

Only one run from top to bottom is needed to complete the leak detection operation of the entire filter, which is also known as the line scanning method. Line scanning acquisition

Connect the probe to the scanning leak detection sampling port in the centralized interface box through an anti-static sampling tube, while the line scanning sampling probe is connected to the collector through a mechanical transmission mechanism

Connect the scanning drive mechanism inside the interface box. Compared to using a rectangular sampling head for scanning leak detection, line scanning leak detection technology has instrument configuration

Features such as low scanning time, short scanning cycle, and simple mechanical drive mechanism.
