Air Purification Treatment in Dust - free Workshop Purification Engineering
2024.11.08
In modern industrial production and scientific research fields, the importance of dust - free workshop purification engineering has become increasingly prominent. And air purification treatment, as a key link among them, directly determines the cleanliness and operation effect of the dust - free workshop. This article will deeply discuss the relevant knowledge of air purification treatment in dust - free workshop purification engineering.
I. The Importance of Air Purification Treatment
Dust - free workshops have strict requirements for air quality because even the tiniest dust particles or microorganisms can have a serious impact on the production or experimental process. In the manufacturing of electronic chips, a slightly larger dust particle landing on a chip may cause a short - circuit in the chip and make the entire chip scrapped. In the pharmaceutical production field, microorganisms in the air may contaminate drugs and endanger the health of patients. Therefore, creating a stable and clean air environment for the dust - free workshop through effective air purification treatment is a necessary condition for ensuring product quality and production safety.
II. The Process of Air Purification Treatment
(I) Primary - efficiency Filtration
Air first passes through a primary - efficiency filter, whose main function is to filter out larger - diameter dust particles, such as hair, fibers, and large - particle dust. Primary - efficiency filters generally use materials such as non - woven fabrics and nylon nets and have a good filtering effect on particles with a diameter greater than 5μm. This stage can effectively protect the subsequent medium - efficiency and high - efficiency filtering equipment and extend their service life.
(II) Medium - efficiency Filtration
After primary - efficiency filtration, the air enters the medium - efficiency filtering process. Medium - efficiency filters can remove dust, microorganisms, etc. with a particle size of 1 - 5μm. Common medium - efficiency filtering materials include glass fiber, polypropylene, etc. Through a multi - layer filter structure, the air is further purified, reducing the content of medium - sized particles in the air and reducing the burden on high - efficiency filtration.
(III) High - efficiency Filtration
This is the core part of air purification treatment. High - efficiency filters can intercept tiny particles with a diameter of 0.3μm and below. For particles with a diameter greater than or equal to 0.3μm, the filtering efficiency can reach more than 99.97%. High - efficiency filters mostly use glass - fiber filter paper as the filtering medium. Under a special folded structure, the filtering area is greatly increased. In some dust - free workshops with extremely high cleanliness requirements, such as ISO1 - ISO3 - level electronic chip manufacturing workshops, the quality of high - efficiency filtration directly determines whether the air cleanliness in the workshop can meet the standard.
III. Other Key Factors in Air Purification Treatment
(I) Airflow Organization
Reasonable airflow organization is crucial for air purification in dust - free workshops. The unidirectional - flow airflow organization mode enables air to flow at a uniform speed and in a single direction, effectively discharging dust particles from the workshop. For example, in a vertically unidirectional - flow dust - free workshop, air flows vertically downward uniformly from the high - efficiency filter at the top, like an air barrier, preventing the diffusion and settlement of dust. In a turbulent - flow clean room, by reasonably designing the positions and numbers of air supply inlets and return inlets, the filtered air is fully mixed in the room to dilute the concentration of dust and microorganisms.
(II) Temperature and Humidity Control
The temperature and humidity in the dust - free workshop also have an impact on the air purification effect. A suitable temperature and humidity environment can not only ensure the normal operation of production equipment but also reduce dust generation and microorganism breeding. Generally, the temperature in an electronic dust - free workshop is usually controlled at 22℃ ± 1℃, and the humidity is between 45% and 55%. In a pharmaceutical dust - free workshop, the temperature and humidity requirements vary slightly according to different production links, but they all need to be kept within a stable range to avoid problems such as air condensation and microorganism reproduction caused by temperature and humidity fluctuations.
(III) Static Electricity Control
In some dust - free workshops for the production of electronic components, static electricity may attract dust particles and may also cause damage to sensitive electronic components. Therefore, effective static electricity control measures need to be taken during air purification treatment. For example, by installing static eliminators and using anti - static - material filters and ventilation ducts, the generation and accumulation of static electricity are reduced to ensure the cleanliness of the air in the workshop and the safety of production.
IV. Maintenance and Management of Air Purification Treatment Equipment
To ensure the continuous and effective operation of the air purification treatment system, regular maintenance and management are essential. For primary - efficiency, medium - efficiency, and high - efficiency filters, they should be regularly inspected and replaced according to their usage conditions. When the resistance of a filter exceeds the specified value, it needs to be replaced in time to ensure the filtering effect. At the same time, the ventilation system, fans, and other equipment should also be regularly maintained, and the operation status, lubrication situation, etc. of the equipment should be checked to ensure that the air can be circulated and purified stably and efficiently in the dust - free workshop.
In conclusion, air purification treatment in dust - free workshop purification engineering is a complex and delicate system engineering. From the air - filtering process to the control of various key factors, and then to the equipment maintenance and management, each link is closely connected.
