Description
Technical Field
The invention relates to an air circulation system and method for isolating pollutants in a production line of a pharmaceutical factory, and belongs to the field of control of cleanliness of pharmaceutical production in the pharmaceutical factory.
Background
The medicine production workshop belongs to a part of pharmaceutical factory production, has extremely high requirements on air cleanliness, and can cause cross contamination by slight deviation, thereby influencing the production flow of medicines. The production line of the medicines is the most important in cleanliness control. The potential pollution threat to the production line medicine cleanliness is caused by the situations that personnel around the production line are processed, personnel in the production workshop move, air circulation is caused when the personnel enter and exit the production workshop, and the like, so that the most strict cleanliness control mode is required for the production line. Workers belong to dynamic variables, and the influence of the dynamic variables on the cleanliness of production line medicines cannot be quantitatively controlled; therefore consider to production water line and add an air curtain again, isolated all gaseous pollutants and particulate matter outside the production water line, also can help the temperature in the stable room simultaneously, also promoted the cleanliness factor of production water line greatly.
In recent years, a few solutions to the cleanliness control problem of a clean factory production line are provided. Patent CN211375437U introduces a cleanliness control system for clean rooms, which collects the street cleanliness data of the clean room through a particle concentration sensor, and controls the rotation speed of a fan filtering unit, so as to meet the requirements of different cleannesses, and this control mode only aims at workshops, and cannot ensure the cleanliness requirements of production lines, and even in relatively clean workshops, there is a possibility that the products on the production lines are polluted by pollutants; patent CN106839180A describes a method for controlling cleanliness of a transfer device by using static pressure difference, which requires opening an outer curtain door, adjusting the air supply amount of a cleaning unit and sterilizing the transfer device by using a sterilizing agent, wherein the sterilization is performed every twenty-four hours, and finally the transfer device is cleaned and the door on the other side is closed, so that good cleanliness can be ensured, but the steps are too cumbersome, and the workload of workers is greatly increased; patent CN108144373A has introduced the aseptic transmission system of aseptic eye ointment material, he sterilizes the aseptic eye ointment material of splendid attire through the sterilization jar, the negative pressure generating device of rethread negative pressure connector transmits, artificial pollution has directly been avoided and the manpower has been saved, but this kind of mode is not fit for each pharmaceutical factory production line, some production lines need accelerate work efficiency through the manpower, can not just thoroughly replace with full-automatic production line because artificial pollution, when such mode is using on those production lines that need use manual operation, just can not solve artificial pollution risk well.
Disclosure of Invention
The invention aims to provide an air circulation system and a method for isolating pollutants in a production line of a pharmaceutical factory.
