The general air shower is a special channel specially set up for the staff and materials to enter the clean room. The purpose is to reduce the dust and bacteria brought by the staff and materials when they enter the clean room, and at the same time, it is to play the role of a closed dust-free room in the airlock room. Generally, it can be used between all clean room and clean room matching.
Air showerIt is to use a high efficiency air filter to filter the air flow, and then spray the body of the staff and the material from different directions through the rotating nozzle, so as to remove the dust on the surface of the person and the material, and then the air with the dust passes through Circulate again after the initial and high efficiency air filter. The overall design of the air shower room is a combination of dynamic fluidics, which is fully automatic infrared induction shower, and the whole process is operated by humanized voice prompts. The double door interlock is adopted, and the door cannot be opened or left at the same time. When the air shower room is working, the double doors must be closed tightly for forced showering.
With the accelerated pace of industry, some industries that require high cleanliness are also changing day by day. People are becoming more and more sensitive to pathogenic bacteria, but now the industrial working environment needs to be in a clean space that cannot be achieved in nature. Inside, although some equipment required for aseptic and dust-free purification projects such as clean rooms or sterile rooms are now used, the biggest problem is still with the staff, because the staff is the biggest source of dust, so When the staff enters the clean room or the sterile room, it is difficult to get out the dust and dust attached to the staff, so it is necessary to install a jet dust removal device in the air shower room to strongly remove the attachment to the staff and clothes Dust and bacteria.
Air showerThe equipment inside is generally pre-filter, main filter, spray port and blower. The filtration efficiency of the pre-filter is about 15%. Mainly to remove relatively coarse dust particles, and this filter device can use water washing or vacuum cleaner to clean the dust; the main filter is mainly to filter the dust above 0.3um, basically the filtration efficiency of 99.99% or more, but this The filter equipment department is very fragile, so when it is blocked, it needs to be reprocessed; the spray port is mainly used to remove the dust particles attached to the human body, and the effect he wants to achieve is to strip the particles; the blower is mainly to clean the air cycle. The high static pressure blower is used, which is mainly used when jetting and air circulation.
In general,Air showerIt is installed at the entrance of a clean room or a sterile room, and there must be no gaps between the wall panels of the clean room. If there is an air leak, pay attention to the installation of the equipment. Generally, the maintenance of the devices in the air shower room should be cleaned within a certain period of time according to the situation. The front filter can be cleaned by washing with water or vacuum cleaning, etc. Generally, it needs to be cleaned 2 to 3 times a month for deterioration. The main filter should be tested 2 to 4 times a year. The clean workshop should decide whether the device should be replaced according to the wind speed value or the pressure measurement value.
