The cleanbench is designed to meet the needs of the cleanliness of local work areas in modern industrial, optoelectronics, biopharmaceutical and scientific research trials. The working principle is as follows: the air is sucked by the fan, filtered through the high-efficiency filter through the static pressure box, and the filtered clean air is sent out in a state of vertical or horizontal airflow, so that the operating area continues to be cleaned under the control of clean air. To ensure the production of environmental cleanliness requirements.
Classification of ultra-clean workbench:
The ultra-clean workbench is divided into a vertical flow ultra-clean workbench (verticalflowcleanbench) and a horizontal flow ultra-clean workbench (horizontal flow cleanbench) according to the direction of the airflow. The vertical flow workbench is louder due to the fan at the top but the wind is vertically blown and used in medical engineering. This guarantees the health of the person; the noise of the horizontal flow table is relatively small, so it is used in the electronics industry and has little effect on health. According to the operation structure, it can be divided into two types: single-side operation and bilateral operation. According to its application, it can be divided into ordinary super-clean workbench and biological (medicine) ultra-clean workbench.
From the number of operators, it is divided into single-person ultra-clean platform and double-cleaning platform; it is divided into two types: the lower suction and the upper suction; from the air supply, it is divided into horizontal air supply and vertical air supply.
Ultra-clean workbench use This is a general-purpose partial purification equipment. The airflow is vertical laminar flow, which can create a local high clean air environment. It is an ideal special equipment for scientific research, pharmaceutical, medical and sanitary, electronic optical instruments and other industries. .
The basic principle of the working principle of the ultra-clean workbench is about the same. The indoor air is filtered through the coarse filter, and the centrifugal fan is pressed into the static pressure box, and then passed through the high-efficiency air filter for fine filtration. Uniform cross-section wind speed passes through the sterile area to form a dust-free and sterile high-clean working environment. However, the airflow direction of the two clean benches is different, and the airflow after the air-purification of the side-flow workbench passes through the work surface from the left or right side. Flow to the opposite side, also from the top to the bottom or from the countryside to the opposite side, can form an airflow barrier to keep the working area sterile, but at the junction of the purified gas and the outer gas, negative pressure can occur due to the flow of the airflow, so that a little The clean air is mixed in, and there is a possibility of pollution. The structure of the flow-type clean bench is relatively closed, and generally only the round hole into which the two arms extend is left, and it is not convenient to operate and take large items.
The outflow type (horizontal type) is to make the purified air flow toward the operator, so the external airflow is not mixed into the operation area, but if the hazardous substance experiment operation is performed, it is disadvantageous to the operator. When the horizontal purification workbench is mostly open, There is no protective baffle. Although it is convenient to operate and take the items, it may be affected by the external airflow and cause air to be mixed.
The purification workbench is a relatively sophisticated instrument that, if used and maintained properly, can achieve good results and extend service life.
The ultra-clean workbench mainly uses high-efficiency filters to purify the air. Its high-efficiency filter is used for a certain service life and needs to be replaced regularly. If the workbench is in a relatively clean environment, such as a GMP workshop, the frequency of replacement is low; if it is just an ordinary laboratory, the high-efficiency filter should be replaced 2 years to ensure its effect.
The length of service life of the clean bench is related to the cleanliness of the air. In the temperate zone, the clean bench can be used in general laboratories. However, in tropical or subtropical regions, the area with a large amount of pollen or dust in the atmosphere should be placed in a good indoor room with double doors. . Under no circumstances should the inlet hood of the clean bench be facing the open door or window to avoid affecting the service life of the filter.
