Curtain wall for building wall installation

The invention belongs to the technical field of building curtain walls, and discloses a curtain wall for building wall installation. A circulation tank; a rectifying and filtering device; a curtain wall ventilation device; an active filtering device; a glass curtain wall; an air inlet device and a sunshade device. By starting the turbofan, the turbofan rotates to drive air to blow towards the filter screens installed on the upper side and the lower side of the turbofan, dust is filtered and purified in the area, and the turbofan can generate vibration when purifying high-speed air entering the area. At the moment, a first spring and a second spring with different pressure coefficients at the upper end and the lower end of the bidirectional telescopic rod are responsible for reducing longitudinal vibration force, a connecting block between the two turbofans is matched with the telescopic rod through a rotating shaft to counteract transverse vibration force, and purified air reaches the indoor space through the
