The present invention relates to a tower-type outdoor air purification device and, more specifically, to an outdoor air purification device installed outside a facility that conducts air purification, thereby purifying outer air and supplying same. The outdoor air purification device comprises: a tower body unit disposed to be spaced apart from one side of the facility and configured in the shape of a tower having a dual wall such that air is filtered and suctioned, while poulticing proceeds inside, and is then discharged； an air supply unit disposed on the upper portion of the tower body unit such that air is supplied to the upper portion thereof, and air is introduced laterally at multiple locations on the outer peripheral edge thereof, mixed with the supplied air, and then supplied； a ventilation filter unit disposed inside the air supply unit and the tower body unit and connected to the facility so as to filter and supply the air mixed and supplied by the air supply unit, and to discharge air circulated inside the facility to the outside； a poulticing facility unit disposed inside the tower body unit so as to produce heat and energy by using photovoltaic energy and to use same for poulticing； and a control unit connected to the ventilation filter unit and the poulticing facility unit so as to control the amount of air supplied from the air supply unit through the ventilation filter unit and to control the production and transfer of heat and electricity by the poulticing facility unit using photovoltaic energy.La présente invention concerne un dispositif de purification d'air extérieur de type tour et, plus spécifiquement, un dispositif de purification d'air extérieur installé à l'extérieur d'une installation qui effectue la purification d'air, purifiant ainsi l'air extérieur et le fournissant.
