Compressed air has become the second largest energy source in modern industry except electricity. The scale of compressed air as a source of energy in developed countries has doubled every five years. In the field of pharmaceutical production, it runs through processes such as fermentation, crystallization, drying, and filtration. In the production of antibiotics and other pharmaceuticals, the quality of compressed air is extremely high. It requires not only oil-free water in compressed air, but more importantly, it is dust-free and sterile. According to scientific statistics, the original 8 cubic meters of air under normal pressure is compressed into 1 cubic meter, which can form compressed air with a pressure of 0.8 MPa, and there will be 320 to 400 million compressed air in the 1 cubic meter of compressed air. Micron dust particles. In addition, the atmosphere will be brought into the air compressor's lubricating oil and mechanical wear debris during the process of being compressed. And the compressed air will be re-reduced into water droplets by a large amount of supersaturated water vapor. Moisture, dust, grease, etc. in the compressed air, if not cleaned up in time, will cause the gas pipeline to corrode and block, causing the pneumatic components to malfunction and the mechanical seals to wear out, which may cause immeasurable to the pharmaceutical manufacturers. loss. In addition, when compressed air is used as a carrier for oxygen or gas is provided by nitrogen gas, it is also caused by failure of biochemical culture and contamination of chemicals due to pollutants and bacteria introduced by oil, water and dust. Therefore, obtaining oil-free water, dust-free, and sterile compressed air is not an easy task for enterprises.
In order to obtain clean compressed air, some pharmaceutical manufacturers purchase “oil-free compressors†at a high price, and believe that this can solve the problem of purification of compressed air. However, among the impurities of compressed air, water, dust, bacteria, etc. account for more than 99%, and oil is only a small part, especially screw compressors. Therefore, water, dust, bacteria, etc. are the main body of removal. In addition, traditional air purification process equipment for mass production has many, large floor space, and high management and operation costs. Therefore, the fundamental solution is to enable the purification system to efficiently remove impurities in the air, and the filter medium has a long service life, and the entire system is safe and effective, and has high operability.
Compared with the traditional purification mode, the outstanding advantages of this 3in1 multi-functional compressed air filter are reflected in the conventional purification, oil-water separation, dehumidification, medium-efficiency filtration, precision filtration and so on. The process is aggregated in a single device to complete. Therefore, it has many advantages such as low investment, small floor space, energy saving, high efficiency, easy operation, and easy management.

Application of compressed air degreasing and water removal filter in the pharmaceutical industry
Compressed air is a major source of power in pharmaceutical production. As mentioned in the GMP, “the compressed air that is in direct contact with the drug is purified and meets the production requirementsâ€. However, in actual production, the difficulty of compressed air purification is more, and the traditional compressed air purification mode is too cumbersome and the operation cost is high. Therefore, the new compressed air purification equipment with low energy consumption, strong applicability and simple use has become a research and development hot spot. In this regard, the engineering and technical personnel of Nanjing Ruishiji International Trade Co., Ltd. carried out joint research through in-depth pharmaceutical enterprises, and technically improved the 3in1 series multi-functional compressed air filter that has obtained international invention patents, so that the equipment was successfully Shandong. Pharmaceutical Glass Co., Ltd., China Pharmaceutical University and many other companies are used in laboratory applications and production. The recent reports on the use of these companies show that the filter has significant improvements in terms of energy consumption and ease of use.
