Abstract

The present invention discloses a medical-grade clean compressed air preparation system and a medical-grade clean compressed air preparation method. The a medical-grade clean compressed air preparation system comprises an air compressor, a pressure buffer tank, a fore-lying filter, a cooling water-removing device, an adsorption drying device, an active carbon filter and a terminal filter, wherein the air compressor, the pressure buffer tank, the fore-lying filter, the cooling water-removing device, the adsorption drying device, the active carbon filter and the terminal filter are sequentially arranged along an air flowing direction. According to the medical-grade clean compressed air preparation system, the cooling water-removing device and the adsorption drying device are sequentially arranged so as to well remove the water from the compressed air while reduce the pyrogen, such that the substance carried in the water can be reduced, and the quality of the compressed air can be improved; and through the filtration combination mode of the sequential arrangement of the fore-lying filter, the active carbon filter and the terminal filter, the dust particles, the oil stains and the microorganisms in the air can be completely removed, such that the obtaining of the clean medical-grade compressed air can be ensured.

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...
