The utility model relates to the technical field of
air filtration, and discloses a hospital
isolation ward air filtration system which comprises a sterilization box, a stirring
assembly, a driving piece and an exhaust
assembly, the upper end of the sterilization box is communicated with an air inlet
pipe and an air outlet
pipe, the stirring
assembly is arranged between the sterilization box and the air inlet
pipe, and the driving assembly provides power for the stirring assembly. The exhaust assembly is arranged between the sterilization box and the air outlet pipe;
disinfectant stored in the sterilization box is stirred through the stirring assembly, so that air makes full contact with the
disinfectant, the
air purification effect is improved, meanwhile, the
disinfectant is stirred, components of the disinfectant are evenly distributed, the
air purification effect is improved, the sterilization box is in a
closed state through the exhaust assembly, and the
air purification effect is improved. According to the air purification device, the volatile disinfectant is prevented from leaking, meanwhile, the
staying time of air in the sterilization box is prolonged, the air purification effect is further improved, after the air stays in the sterilization box for a period of time, the air is exhausted from the air outlet pipe through the exhaust assembly, and then air purification is completed.
