Mastering the basic knowledge and main purposes of purification engineering can show the necessary basic theory for the future basic construction work of architectural engineering design. In general, the basic knowledge and main purposes of purification engineering are given:

1. Basic knowledge

　　First, the basic principles of cleaning. The untreated gas undergoes primary cleaning first, and then performs medium-efficiency cleaning according to the air-conditioning fan. The medium-efficiency cleaned air is sent to the high-efficiency clean air outlet by the centrifugal fan according to the pipeline, and then enters the house. The fluidity of the cyclone in the house brings away the floating dust, germs and other dust particles in the indoor air quality, which are then removed according to the ventilation blinds.

Secondly, the common structural raw materials for purification projects. 50mm thick sandwich color steel plates are usually used for the walls and ceilings of the production workshop, and special air-oxidized aluminum alloy profiles are usually used for curved wall feet, doors, and windows. The road surface usually uses epoxy resin artesian epoxy floor or high-grade wear-resistant plastic floor. If there are anti-static regulations, it must be an anti-static type. The return air duct is made of hot-dip galvanized sheet, and flame-retardant plastic PF polyurethane foamed plastic sheet is used outside. On the other hand, the high-efficiency air outlet of the purification project generally uses a stainless steel plate structure, and the punching mesh plate uses a spray-painted aluminum alloy plate.

　　Finally, the system software is composed. The purification project is usually pided into two parts: clean and dust-free workshop and production workshop purification equipment. The purification equipment of the production workshop is composed of three basic components: dressing room, air shower room and clean room.

2. Main purpose

Nowadays, many manufacturing industries have just begun to understand the necessity of purification projects, and are competing to invest in the basic construction of dust-free workshops, clean workshops and other equipment. On the whole, the key to purification engineering is centralized in laboratories, food production workshops, clinics, electronic device production workshops, biomedicine and other industries. For the laboratory, the use of the purification workshop will reduce the interference of gas dust particles and positive ions in the whole process of the test, and improve the test precision. For food companies, the purification workshop can reduce the risk of food environmental pollution and improve the safety factor of food. For the electronic device production workshop, the purification workshop can make the temperature, environmental humidity and the concentration of micro-particles in the production workshop meet the electronic component product standards, and ensure the working characteristics and credibility of the electronic components.

　　In other words, the application of purification engineering in the production and manufacturing of social development is very common, which also reminds people that they should master the purification engineering carefully and grasp the relevant professional knowledge. Only in that way can the design plan of the purification project be constructed to ensure quality, and the purification workshop created can give full play to greater effects.
