Purification engineering refers to the control of the cleanliness, temperature and humidity of the atmosphere contacted by products (such as silicon chips), so that products can be produced and manufactured in a good environment. The design and construction process of this environmental space can be called purification engineering.
Air purification treatment scheme in purification engineering
● the air purification treatment of air cleanliness at all levels in the purification project shall adopt three-stage filtration of primary effect, medium effect and high efficiency air filters. 100000 level air purification treatment, sub high efficiency air filter can be used instead of high efficiency air filter.
Operating room purification, workshop purification, laboratory purification, EDE purification
● the selection, arrangement and installation of air filter shall be in accordance with the following requirements: the primary air filter shall not be oil immersed; the medium efficiency air filter shall be set in the positive pressure section of the purified air conditioning system; the high efficiency air filter or sub high efficiency air filter shall be set at the end of the purified air conditioning system, and the installation method of high efficiency air filter shall be simple and reliable, and leakage detection is appropriate And replacement; medium efficiency, sub high efficiency and high efficiency air filters should be selected according to the rated air volume; high efficiency air filters with similar resistance and efficiency should be set in the same purification workshop.
● when determining the centralized or decentralized purified air conditioning system, comprehensive consideration shall be given to the characteristics of the production process and factors such as the cleanliness level, area and location of the air in the purification workshop. Where the production process is continuous and the clean room or purification workshop has a large area, the centralized purified air conditioning system should be used for the clean room with centralized location, strict noise control and vibration control requirements.
● if electric heating is required for purified air conditioning system, tubular electric heater shall be selected, which shall be arranged on the windward side of high efficiency air filter, and fire safety measures shall be taken.
● the forced draft fan can be selected according to the total air supply volume and total resistance value of the purified air conditioning system, and the resistance of medium efficiency and high efficiency air filter should be calculated as twice of its initial resistance.
● in addition to the DC system and the system with duty fan, the anti pouring measures shall be taken to prevent the outdoor polluted air from entering the purification workshop through the new air inlet.
● the purified air conditioning system shall be designed to make reasonable use of return air. If a large number of harmful substances are generated in the process and local treatment cannot meet the health requirements, or there is harm to other processes, return air shall not be used
