A Brief Discussion on the Development Factors and Variables of Hunan Purification Engineering
Purification engineering can effectively utilize the six cost element variables mentioned below, provide selectable planning plans, improve fundamental purification engineering planning and standards, and strive to meet the needs of the factory. Through these methods, we can reduce the cost of purification engineering projects. Suitable for the planning and construction of purification engineering in the biopharmaceutical, microelectronics, and food processing industries.
1. Ventilation rate
The ratio of pollutants in the room and the occurrence of practical particles are the main factors affecting the frequency of air exchange in engineering. The speed of removing particles is crucial during the production process without affecting any other factors.
2. Unidirectional, turbulent, vertical or horizontal airflow
In many cases, unidirectional airflow is only used in small spaces and sensitive areas of purification projects, and in micro environments. The source of pollutants may exist in glove boxes, filtration modules, and other places. Most plans are outside of the overall unidirectional airflow purification project, and unidirectional airflow can only be completed when there are no workers, production equipment, or exhaust devices in these areas.
3. Air filtration
Other equipment can also be selected based on their use outside of purification engineering, such as using HEPA filters with carbon adsorption or synthetic filters with similar functions to treat VOCs in circulating air and fresh air treatment systems, electrostatic filtration boxes, and so on. In the purification engineering market, fan filtration is no longer a new product. Proper application of it can provide excellent and economical solutions for many high-level purification projects, especially in buildings with limited ceiling height.
4. Air pressure difference
Boosting is necessary to ensure that the project stays away from pollution in its vicinity, control the flow of harmful pollutants, prevent cross contamination between different areas, and assist in maintaining the required temperature and humidity levels. The pressure difference between the purification project and other areas within the relevant corridors and equipment should be maintained between 0.25 and 0.005 inches of water column (in. w. g.). The pressure difference required by general pharmaceutical companies is higher than this, and stacked pressure differences are used between different areas to prevent cross contamination.
5. Temperature control
Changes in temperature and humidity can cause errors in production equipment, which in turn affect the repeatability of the production process, ultimately leading to a decrease in product qualification rate and increased waste. Therefore, the strict temperature control requirements for purification engineering are obvious, and this cost is necessary. Usually, engineers are required to reduce construction costs during planning, while also requiring accurate temperature control over a large area.
6. Humidity control
The relative humidity in each purification workshop is controlled by some humidity regulators. When it is necessary to achieve accurate humidity control in purification engineering, the adiabatic humidification effect of fresh air in the air conditioning box is usually used to complete it. Partial changes in humidity level can be controlled by an ultrasonic humidity regulator, which is located in the duct static pressure box before final filtration.
