Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] Such as figure 1 As shown, the present invention consists of a closed end valve 1, an aerosol detection section 2, a mixing section 3, an upstream sampling section 4, a filter installation section 5, a scanning leak detection section 6, a closed door 7, and a top closed valve 8. composition. During the operation, the airtight valves 1 and 8 are in an open state; during the disinfection process, the airtight valves 1 and 8 and the airtight door 7 are in a closed state to avoid spillage of the disinfectant.

[0033] Such as figure 2, As shown in 3 and 4, the detection aerosol generation section 2 is connected to the airtight valve 1 and the mixing section 3, and the detection aerosol generation section is provided with a dust-generating port 9, and the dust-generating port is externally connected to a quick-plug interface 24. The mixing section 3 is composed o...

Abstract

The invention discloses a high-efficiency air filter unit capable of on-site leak detection and in-situ disinfection. The invention consists of aerosol detection generation section, mixing section, upstream sampling section, high-efficiency filter compaction device, scanning leak detection device, disinfection device, filter resistance monitoring device and other parts, and the filter compaction device adopts eccentric compaction mechanism , The filter replacement method is the bag-in-bag-out method, the scanning leak detection device is an automatic scanning leak detection device, and the detection technology adopts the line scanning detection method. The invention is characterized by high-efficiency air filtration unit box body sealing, anti-sterilant corrosion, safe and convenient filter replacement; the invention meets the biological safety requirements, and is suitable for air supply and exhaust disposal systems of high-level biological safety laboratories.

Description

technical field [0001] The invention relates to the field of biological safety protection technology and equipment, more specifically, a high-efficiency air filter unit and detection technology capable of on-site leak detection, in-situ disinfection and safe and convenient filter replacement. Background technique [0002] Many common and routine experimental operations in the biosafety laboratory will produce infectious aerosols, whose particles can remain in the indoor air for a long time, and some particles can enter the lungs with the air that people breathe to cause infection; the biosafety laboratory Harmful aerosols or indoor polluted air discharged into the atmosphere will infect people or animals, pollute the surrounding environment, seriously threaten human life and health, and even cause major public health incidents. [0003] So far, high-level biosafety laboratories in Western developed countries such as the United States, Canada, Germany, and France have used in...
