The clean pipeline of pharmaceutical water system generally includes purified water system, material system, special gas system, vacuum system, water injection system and pure steam system. The purification treatment method that the process production line with ultra-high cleanliness grade (such as 1 grade or1grade) is placed in the pipeline isolated from the indoor air environment is called clean pipeline. This method requires that the process production must be automated, and the high-efficiency filter must be based on 0. 1μm dust particles to achieve ultra-high cleanliness.
The design of clean pipeline in pharmaceutical water system should determine the air volume according to the volume of clean space and the required air exchange times, determine the wind speed according to the noise restriction conditions, and determine the cross-sectional area of air duct according to the wind speed, air volume and system loss. The design has matured three purification treatment methods: whole room purification, local purification (including the combination of whole room purification and local purification) and clean tunnel. In engineering design, one or two purification methods should be selected as the design scheme according to the specific situation.
The main difference between the hydraulic calculation in clean pipeline and that in common water supply pipeline is that the special requirements of microbial control on hydrodynamic characteristics in water system should be seriously considered. The specific difference lies in the increasing use of various disinfection and sterilization facilities in pharmaceutical process water systems. The traditional one-way DC water supply system is changed into series circulation mode.
Under the condition of meeting the process requirements, the local purification method should be selected as far as possible in the design of clean pipeline of pharmaceutical water system. Local purification adopts local purification equipment, which is realized in general air conditioning environment. Because the local purification equipment is generally produced by professional factories, the quality of the equipment is high, which can speed up the on-site construction, so this scheme can be given priority in the reconstruction project.
