Medical hospital ward air sterilizing and purifying device

Abstract

The invention provides a medical hospital ward air sterilizing and purifying device. The medical hospital ward air sterilizing and purifying device comprises an activated carbon adsorption filter screen, an HEPA filter screen, electrostatic adsorption plates, an air channel coil, ultraviolet sterilization lamps and pipeline fans, wherein a first-stage purifying device comprises a first hood housing, a coarse filter screen, the activated carbon adsorption filter screen and the HEPA filter screen; the coarse filter screen, the activated carbon adsorption filter screen and the HEPA filter screenare arranged in the first hood housing; a second-stage purifying device comprises a second hood housing, ionization plates and electrostatic adsorption plates; the ionization plates and the electrostatic adsorption plates are arranged in the second hood housing; an air sterilizing device comprises a third hood housing and the air channel coil arranged in the third hood housing; the air channel coil comprises straight pipes and bent pipes; each ultraviolet sterilization lamp is arranged in the corresponding straight pipe; and each pipeline fan is mounted in the corresponding bent pipe. Throughthe adoption of the medical hospital ward air sterilizing and purifying device disclosed by the invention, dust removal by filtration, dust removal by electrostatic adsorption and ultraviolet ray sterilization are sequentially performed on air; and dust granules in the air are filtered, so that finally, the guided air is clean and tidy, and the situation that continuous pollution of microorganismsin the air caused by secondary dust raising is avoided.

Description

technical field [0001] The invention belongs to the technical field of air purification and medical purification equipment, in particular to an air disinfection and purification device for medical wards. Background technique [0002] The air disinfector is only effective for air and has no disinfection effect on the surface of objects. The general ward is open, and there are many people coming and going to see the patients, resulting in more dust on the surface of indoor objects. When the disinfection machine is working, secondary dust will be generated, causing continuous air microbial pollution, and eventually leading to disinfection failure within the specified time. , This is also the reason why some environments are unqualified after normal disinfection or the bacteria do not decrease but increase during the disinfection process. [0003] The "air duct design" of the air purifier has a great relationship with the "air volume". Whether the air duct design is reasonable...
