Abstract

The invention discloses a pharmaceutical-grade clean compressed air preparation system and method. The system comprises an air compressor, a pressure buffer tank, a front filter, a cooling dewatering machine, an adsorption dryer, an active carbon filter and a terminal filter which are sequentially arranged in the air circulation direction. According to the pharmaceutical-grade clean compressed air preparation system, the cooling dewatering machine and the adsorption dryer are sequentially arranged, so that a heat source is effectively reduced, moisture contained in compressed air is better removed, carried substances in water are reduced, and the quality of the compressed air is improved; meanwhile, by the adoption of a filter combination mode that the front filter, the active carbon filter and the terminal filter are sequentially arranged, dust particles, oil dirt and microorganisms in the air are fully removed, and it is guaranteed that the pharmaceutical-grade clean compressed air is acquired.

Description

technical field [0001] The invention relates to the field of pharmaceutical production, in particular to a pharmaceutical-grade clean compressed air preparation system and method. Background technique [0002] The compressed air used in the early days was mainly used as the power source of pneumatic components such as instruments and cylinders. Its preparation method mostly adopts common air compressor. At present, with the improvement of pharmaceutical equipment automation technology, pharmaceutical factories generally use compressed air that has been simply dried and filtered. But with the continuous upgrading of pharmaceutical technology and equipment. Compressed air is more and more used as a process air source, directly contacting medicines or inner packaging materials of medicines, becoming an important factor that directly affects the internal quality of medicines. Therefore, the quality of compressed air is very important. In the quality requirements of pharmaceut...
