DEVICE FOR DISINFECTING THE AIR IN UNDERGROUND RAILWAY CARRIAGES

The device is intended for desinfecting the air in underground railway passenger carriages with the aid of bactericidal UV radiation. A bactericidal lamp is fixed in an upwardly open body of the device by means of vibration-damping elements, the lamp being arranged in a recess in the body with a gap between the body and lamp. A detachable cover is fixed on the body from below under the lamp such that air passes freely between the body and cover. Furthermore, the body recess and the cover serve as means for protecting against the escape of UV radiation into the passenger saloon and air conditioner. In order to reduce vibration and aerodynamic noise, a layer of vibration-damping material is applied to the lower surface of the body, and a sound-absorbing layer is applied to the upper surface of said body - and is fixed thereto with the aid of a lattice. The edge of the body is inclined downwards, which makes it possible to smoothly increase the cross section of the duct for the passage of air through the device and reduce pressure losses.
