The invention relates to the field of
environmental protection, and particularly discloses an
air purification device of a clean room. The
air purification device comprises a shell, an air inlet, an induced draft fan, a ventilation opening and an air outlet
pipe; a filter screen cylinder is fixed on the right side of the ventilation opening, a vertical rotary inner core is coaxially arranged in the filter screen cylinder, a plurality of first partition plates which are staggered vertically are fixedly arranged on the right side of the filter screen cylinder, a plurality of heaters are fixedlyarranged between every two adjacent first partition plates, and a temperature adjusting chamber is arranged at the right end of the shell. According to the
air purification device, the rotary inner core is arranged in the filter screen
barrel, on one hand, the passing performance of air in the filter screen
barrel can be ensured, the filtered air can be discharged in time, and on the other hand, filtered dust on the filter screen cylinder is swept through a
brush plate installed on a
brush plate groove, so that the dust can be removed from screen holes and is prevented from being blocked; thefiltered air is subjected to sterilization treatment by virtue of high-temperature heating treatment, so that
bacteria in the air are reduced, and the requirements of the clean room are met.
