A device for purification of air in a building

Abstract

A device for purification of air in a building is innovatively provided. A cylinder, a cover and a tank body are welded to a shell of the device in order from top to bottom. A suction ventilator is disposed in the cylinder. The bottom of the tank body is provided with a wind inlet and the top of the cylinder is provided with a wind outlet. An upper drawer type filter screen body and a lower drawertype filter screen body are disposed in the tank body. The lower filter screen body is dust collection filter screens, and the upper filter screen body is deodorization filter screens. Each of the upper and lower filter screen bodies includes two filter screen layers. The space between the two filter screen layers of the upper filter screen body is filled with activated carbon. The wind inlet isprovided with a louver the slat angle of which is adjusted by an adjusting mechanism. Air is fed from a lower part and discharged from an upper part in the device, and the device can rapidly remove unpleasant odor in passageways through filtration and discharge fresh air.

Description

technical field [0001] The invention belongs to the field of air purification, and in particular relates to an air purification device in a building. Background technique [0002] Existing office buildings generally do not set fixed smoking areas, and bathrooms and corridors become the default smoking areas. Because bathrooms generally have exhaust systems, the smell of smoke will be quickly discharged by the exhaust system, but corridors In order to ensure the temperature inside the building, the windows in the corridor will not be opened all the time in these two seasons, or even if the outdoor temperature is higher in summer and lower in winter. Even if it is opened, the smell of smoke or peculiar smell lingers in the corridor for a long time, that is, it will not be discharged quickly. The environment in the corridor is worrying and needs to be improved urgently. Contents of the invention [0003] Aiming at the technical problems mentioned in the background art, the t...
