Methods and Principles of Clean Booth Air Cleaning Treatment
Methods and Principles of Clean Booth Air Cleaning TreatmentClean booth only uses a closed structure, reasonable air handling, reasonable airflow organization, reasonable pressure difference, and its micro-environment to achieve the required air cleanliness, to meet the production requirements.Control of clean booth air cleanliness a method is to send clean air to dilute indoor polluted air, and another method is to accelerate the discharge of high concentrations of indoor polluted air. To maintain the cleanliness of the air required by the production environment, a variety of integrated measures to achieve the goal. These integrated measures include the following aspects. I. Control the source of pollution, reduce pollution Clean booths as far as possible to use less pollutants generated by the process and equipment, to prevent the production process of pollutants to the surrounding spread; to reduce the number of people and materials brought into the indoor pollutants. II. Prevent the clean booth outside the pollution invasion indoors. This is a clean booth clean room to control the main ways of pollution, air purification, and indoor pressure control methods should be considered. According to the different cleanliness requirements of the room, different ways to send out different treatments, and different amounts of clean air, while discharging the dirty air produced in the room, so that the indoor air maintains the required level of cleanliness. The clean treatment of the incoming air is a key link, which is the reason why the number of air changes in the clean booth is greater than that in a general air-conditioned room. The smaller the cleanliness, the greater the air change. For indoor positive pressure control, industrial clean room and general biological clean room using positive pressure measures. III. Clean up the clean booth pollution that has occurred. This is also the key to reflecting the function of the clean booth. Reasonable airflow organization, that is, through the location of the air supply and return air, size, and form of careful design, so that the indoor airflow is in the appropriate direction, to avoid dead ends and secondary pollution. Different airflow organization directly affects the difficulty of construction and the cost of the project. IV. Flow rate control Clean booth airflow rate should be high to avoid interference by other factors (such as heat flow), but not too high. The flow rate is too high, and indoor dust flying, resulting in pollution. |
