What are the environmental requirements for an air shower and high-efficiency air supply vents?
What are the environmental requirements for an air shower and high-efficiency air supply vents?What are the environmental requirements for an air shower and high-efficiency air supply vents? What kind of environmental requirements are needed to install an air shower and high-efficiency air supply vents? Every industry needs to prepare environmental requirements for installing high-efficiency air filters, but users do not have technicians to install high-efficiency air supply vents. For example, the on-site environment is sanitary and dust-free, otherwise, the installation of air filters will not meet the required standards.Before installing high-efficiency air supply vents, please complete all decoration and installation projects in the clean installation room to support comprehensive cleaning and scrubbing of the clean room. According to the requirements of the specification, a clean air conditioning system must be commissioned. In addition, it is necessary to continuously test run for 12 to 24 hours (air blowing). After air blowing, clean the clean room again and scrub. In this case, workers wear work clothes and work shoes and immediately perform effective air filter installation. When installing high-efficiency air supply vents, it is better to work in a group of 6 people, with 2 people specifically opening the box and applying sealing strips, and the other 4 people being divided into two groups for installation, with the division of labor and cooperation. The pasting of the sealing strip is an important task. Poor cutting, careless pasting, and assembly will directly affect the installation quality of the filter. High-efficiency filter frames are divided into wooden frames and metal frames. Since the use of wooden frame high-efficiency filters is restricted in biological clean rooms, metal frame high-efficiency filters are now mostly used.  Before installing the high-efficiency filter, please wipe the high-efficiency air supply port and the inside of the static pressure tank again to make them clean. Then apply glass rubber on the four seamed corners of the sealing strip, and immediately put in the high-efficiency filter air inlet. Applying glass paste acts as a double insurance, and leakage is mainly at the joints at the four corners. Installation workers should sit at appropriate heights on both sides of the herringbone pedal and push the high-efficiency filter into the air supply port in parallel. There are four pressure plate fittings in total. Two of the pressure plate fittings should be installed diagonally and do not tighten them at first. After all four pressure plate brackets are installed, use your fingers and visual inspection to adjust the filter so that the surrounding gaps become even, the width of the sealing compression surface narrows and becomes even, and the sealing performance is improved. If you do not need to detect leaks in the filter and surrounding gaps, you can install wipe-clean high-efficiency air diffuser panels. When it is necessary to check for leakage, install the diffuser plate after passing the leakage check. When installing the diffusion plate, correspond to the positive high-efficiency filter, and the surrounding gaps should be consistent to prevent the bolts from being overtightened. The scrubbing of the diffuser plate must be done by the responsible person. Because general diffusers are not scrubbed before leaving the factory, they should be cleaned with detergent water to remove oil and dust before installation. Wash with tap water, wipe off the remaining water with a dry cloth that cannot remove fibers, and store in a clean environment for standby. The air shower is a necessary passage for people to enter and exit the clean room, and it also functions as an airlock to seal the clean room. To reduce the large amount of dust particles caused by people entering and exiting, the clean air flow filtered by the high-efficiency filter is optional The nozzles spray onto the person from all directions, effectively and quickly eliminating dust particles. Before the air shower is manufactured and shipped from the factory, the air shower needs to be inspected to ensure that the air shower meets the quality standards and that the filtration level, clean airflow speed, etc. meet relevant standards. The detection and test methods of the air shower room include high-efficiency filter leakage detection, average wind speed detection of nozzle airflow, pressure difference detection between the inside and outside of the air shower room, withstand voltage detection and insulation resistance, etc., to ensure that all indicators of the air shower room are qualified and comply with relevant regulations. Quality Standard. Principle and structure of air shower: The air/cargo shower is a necessary passage for people/cargo to enter and exit the clean room, and it also functions as an airlock closed clean room.  The purpose of the air shower is to reduce the large amount of dust particles caused by the entry and exit of people/cargo. The clean air flow filtered by the high-efficiency filter is sprayed from all directions by the rotatable nozzle to the people/cargo, effectively and quickly removing the dust particles. The final dust particles are filtered by the primary and high-efficiency filters and then recirculated into the air shower area. To achieve a better shower effect, the air/cargo shower room is designed with a nozzle outlet wind speed that can reach more than 25m/s, and the wind speed blowing onto the human body is 18m/s. The factory's initial air shower time is set to 15 seconds. The air shower room provides a modular assembly method and can be assembled into air shower sizes of various lengths according to actual needs. |
