Example 1:
referring to fig. 1, there is shown a medical grade air purification device using cylindrical HEPA filter screen for disinfection, driven by a driving motor, a rotatable cylindrical HEPA filter screen 10 is installed on a gas filtering channel of the purification device (for example, air enters from the middle and then passes through the filter screen and then is output from the periphery, or enters from the periphery and then passes through the filter screen and then is output from the middle), the ventilation volume per hour of the cylindrical HEPA filter screen 10 of 11-12 grade HEPA filter screen can meet the target requirement that the circulating air volume is more than 8 times of the room volume, in order to meet the requirement of sterilization and disinfection, a fixed rubber roller 30 capable of absorbing disinfectant is arranged on one side of the cylindrical filter screen as a disinfectant transfer roller, the disinfectant transfer roller has a hollow inner cavity 31, a transfusion pipeline 22 connected with a liquid storage tank 20 is connected with the hollow inner cavity 31, and the disinfection is controlled by a disinfectant injection control motor, the skin mucosa disinfectant (such as compound quaternary ammonium salt disinfectant) with virus inactivation effect stored in the disinfectant liquid storage tank 20 is injected into the hollow inner cavity 31, and further passes through the water-absorbing rubber roller, the disinfectant permeates to the roller surface of the disinfectant liquid transfer roller, and is contacted with the cylindrical HEPA in a rotating way, so that the disinfectant liquid attached to the roller surface is transferred and adsorbed onto the HEPA filter screen, and further acts on the air flowing through the HEPA filter screen when the air flows through the HEPA filter screen, and the corresponding sterilization and disinfection operation is completed. That is, the roll walls of the transfer roll need to be designed as a permeable hydrophilic material or structure.
Furthermore, the injection amount and the injection frequency of the disinfectant can be adjusted through a set control key on a control panel, the disinfectant injection control motor 21 is driven to inject a proper amount of disinfectant into the idler wheels, and the whole cylindrical HEPA filter screen is driven by the motor to rotate, so that the disinfectant is uniformly absorbed by the HEPA filter screen. When the air after primary filtration passes through the HEPA filter screen, viruses can be naturally adsorbed on the filter screen and killed by the disinfectant.
The injection amount and the injection frequency of the disinfectant, the rotation frequency of the cylindrical HEPA filter screen, the residual disinfectant display and other information can be synchronously displayed on a set digital control display, so that the digitization and automation control performance of the digital control display are improved.
Example 2:
referring to fig. 2, another structure of the medical-grade air purification device of the present invention is illustrated, which is different from embodiment 1 in that the HEPA filter screen in this embodiment is designed as a flat-plate HEPA filter screen, that is, a roller way 40 for the disinfection solution transfer roller 50 to roll back and forth is formed in a space between two flat-plate HEPA filter screens 41 and 42, and similarly to embodiment 1, the disinfection solution transfer roller 50 with disinfection solution attached to a roller surface is driven by a driving motor thereof, and when rolling back and forth along the roller way 40, due to the upper and lower surfaces of the disinfection solution transfer roller 50 and the HEPA filter screens 41 and 42 are attached to each other or act with each other, the disinfection solution attached to the surface of the roller way is transferred to the surfaces of the upper and lower HEPA filter screens.
