Laminar flow operating room requires not only highly clean air (the air entering the operating room must be purified by high efficiency filter first), but also control the flow direction of airflow (i.e. using laminar flow super-clean device) to form a positive pressure environment in the operating room, so that airflow can flow from the operating area with high cleanliness to the area with low cleanliness. A fine, thin layer of airflow is conveyed in the same direction at a uniform flow rate, and dust particles (dust particles) and bacteria in the airflow are removed and discharged. At present, laminar operating room is divided into vertical laminar flow and horizontal laminar flow. What problems should be paid attention to in the high efficiency filter of laminar ceiling in operating room? Ed Purification tells you:
Maintenance points of high efficiency filter for laminar air supply ceiling in operating room:
1. Inspection methods: observation or white silk wiping inspection.
2. For high-efficiency filters, the installation direction must be correct: the vertical connection between the filter and the frame, strictly prohibit leakage, deformation, damage and rubber leakage, etc. After installation, it must ensure that the inner wall is clean, free of floating dust, oil, rust and sundries.
3. Before installation, it is not allowed to tear or open the packaging bag or film by hand; air filters should be stored in strict accordance with the direction standard marked on the packaging box of high-efficiency filters; during the handling of high-efficiency air filters, they should be handled and placed lightly to avoid severe vibration and collision.
Cleaning rooms must be thoroughly cleaned and cleaned. If dust accumulates in the air conditioning system, it should be cleaned and cleaned again to meet the cleaning requirements.
If the high efficiency filter is installed in the technical interlayer or ceiling, the technical layer or ceiling should also be cleaned and wiped thoroughly.
The appearance inspection must be carried out at the installation site, including: whether the filter paper, sealant and frame are damaged or not; whether the side length, diagonal line and thickness dimensions meet the requirements; whether the frame has burrs and rust spots (metal frame); whether there is product qualification certificate and whether the technical performance meets the design requirements.
4. Transportation and storage of high-efficiency filters should be shelved in accordance with the direction of the factory logo. In the course of transportation, it should be handled lightly to prevent violent vibration and collision, and not be forced to load and unload.
5. When installing the high efficiency filter, the arrow on the outer frame should be in accordance with the direction of airflow; when it is installed vertically, the direction of the fold of the filter paper should be vertical to the ground. Installation of crude flat or folding filters should make the galvanized mesh face in the direction of the back of the wind. When installing the bag filter, the length direction of the filter bag should be perpendicular to the ground, and the direction of the filter bag should not be parallel to the ground.
6. When the equipment is running, it is generally not necessary to replace the filters; if the filters cannot be stopped and replaced because they have reached the replacement deadline, the coarse and medium-efficiency filters can only be replaced in the case of non-stop fan; the sub-high-efficiency filters and high-efficiency filters must be replaced after stopping air supply.
7. Sealing gaskets between high-efficiency filters and connecting frames must be tight and leak-free to ensure the filtering effect.
