The hospital operating room purification laminar flow hood is mainly composed of a box body, a fan, a primary air filter, a damping layer, a lamp, etc., and the shell is sprayed with plastic. The product of clean laminar flow hood in hospital operating room can not only be hung, but also be supported on the ground, with compact structure and convenient use.
The high efficiency filter of the hospital operating room purification laminar flow hood and the air supply ceiling of the clean room shall be transported and stored according to the direction marked by the manufacturer. During transportation, handle with care to prevent violent vibration and collision, and do not force loading and unloading.
When the high-efficiency filter is installed on the purification laminar flow and air supply ceiling in the operating room of the hospital, the arrow on the outer frame shall be consistent with the air flow direction; when it is installed vertically, the filter paper fold direction shall be perpendicular to the ground. The installation of coarse effect flat or folding filter shall make the galvanized mesh face in the direction of the air outlet back. When installing the bag filter, the length direction of the bag shall be perpendicular to the ground, and the direction of the bag shall not be parallel to the ground.
During the operation of the equipment for the purification laminar flow and air supply ceiling in the operating room of the hospital, the filter should not be replaced generally; if the filter cannot be stopped for replacement due to the expiration of the replacement period, only the coarse and medium efficiency filters can be replaced without stopping the fan; the sub high efficiency filter and high efficiency filter can only be replaced after the air supply is stopped.
The gasket between the high efficiency filter of the air supply ceiling and the connecting frame must be tight and leak free to ensure the filtering effect.
There are two kinds of installation methods for the purification laminar flow and the air supply ceiling in the operating room of the hospital, i.e. the internal installation of the fan and the external connection of the fan. There are two kinds of installation methods: the suspension type and the floor bracket type laminar flow hoods, which are to pass the air through the fan at a certain wind pressure through the high-efficiency air filter, and then to equalize the pressure by the damping layer. The clean air is sent into the working area in a vertical laminar flow, so as to ensure that the working area reaches the high cleanliness required by the process.
The purification laminar flow and air supply ceiling in the operating room of the hospital are equipped with high-efficiency filter box and high-efficiency filter above the air inlet of the static pressure box according to the air flow direction, the air inlet of the static pressure box is equipped with a distributor, and the leakage resistance layer is set below.
The hospital operating room purification laminar flow and air supply ceiling is to pass the air through the high-efficiency filter at a certain wind speed, forming a flow sharing layer, making the clean air flow in a vertical direction, thus ensuring the cleanliness of the working area to meet the process requirements.
