Purification engineering technology has been widely used in electronics, nuclear, aerospace, bioengineering, pharmaceutical, precision machinery, chemical industry, food, automobile manufacturing and other high-tech industrial fields and modern scientific fields. At present, many industries have implemented purification projects, which can eliminate pollutants and harmful gases in the air (control), and provide a clean and comfortable environment. Clean engineering is mainly concentrated in laboratory, food workshop, operating room, electronic workshop, biopharmaceutical and other fields.
1. Application of purification engineering in food industry
In order to ensure food safety, microbial content must be controlled in a reasonable range. Through food workshop purification, not only can improve the safety of food, but also can improve the flavor and optimize the processing process.
2. Application of purification engineering in laboratory
Dust and ions in the air will interfere with the experimental process and affect the accuracy of the experiment, especially in some high-tech research and development places, there are almost strict requirements for dust ions.
3. Purification engineering applied to production workshop
Due to the development of advanced technology, the demand for high precision and miniaturization of products is more urgent. For example, the research and manufacture of VLSI circuits need clean production workshops. For example, the production of semiconductors requires a dust-free workshop to ensure that the particles, temperature and humidity in the working environment meet the standards. Any particles, temperature and humidity not up to the standard may affect the performance and reliability of manufacturing devices.
4. Application of purification engineering in medical industry
The postoperative infection rate was reduced from 8.9 to 0.26 by using operation room purification project. Operating room purification has become an important indicator of hospital medical level, especially in some large hospitals, high-level purification operating room is needed to provide suitable space for complex surgery such as organ transplantation.
