MOBILE SET TO DECREASE DEGREE OF POLLUTION OF ZONES OF STAGNATION OF SURFACE ATMOSPHERIC LAYER BY EXHAUST GASES Russian patent published in 1998 - IPC

FIELD: formation and protection of ecologically clean habitat for man. SUBSTANCE: mobile set to decrease degree of pollution of zones of stagnation of surface atmospheric layer by exhaust gases includes semi-rigid controlled aerostatic apparatus with thermostatic ballasting and gondola. Upper end of restoring elastic hose is attached to gondola with the use of hinge suspension, its lower intake end is joined via quick-separable lock to suction fixture anchored on self-propelled ground vehicle. Suction fixture is fitted with reversible pressure fan with guiding apparatus. Restoring elastic hose has permissible restoring elongation equal to 0.15-0.35 of its length. Length of hinge suspension of restoring elastic hose and distance between adjacent spacer rings amounts correspondingly to 0.05-3.0 and 0.1-3.0 diameters of cross- section of restoring elastic hose. Maximum length of cross-section of restoring elastic hose together with fairing and diameter of restoring elastic hose exceed maximum width of this cross-section and curvature radius correspondingly by 1.2-3.5 and 1.3- 12.0 times. Upper and lower ends of flexible coupling of adjustable length are anchored correspondingly on gondola and on quick-separable lock. EFFECT: possibility of maneuvering under conditions of megapolis and fast transportation by air to zones of stagnation of surface atmospheric layer with increased degree of pollution. 2 cl, 4 dwg
