METHOD OF REDUCING EXPOSURE TO EXHAUST FUMES AUTONOMOUS locomotive catenary electrified railway lines AND DEVICE FOR ITS IMPLEMENTATION

摘要

1. A method for reducing the impact of exhaust gases autonomous locomotives catenary electrified railway lines, comprising the steps that the exhaust gas flow directed upwards from the gas pipe of the locomotive engine, wherein the exhaust gas flow to provide additional acceleration and velocity in planes inclined to the vertical a vent tube axis, for swirling and expanding the gas flow, intensifying the mixing of exhaust gases with the ambient air, reducing vertically th component potoka.2-gas velocity. Device for reducing the impact of exhaust gases autonomous locomotives catenary electrified railway lines is designed as a vane machine with radially extending guide vanes, the surface of which, facing towards the flow of exhaust gases, is inclined to the vertical axis of the gas delivery tube at an angle α, of from 25 to 65 degrees for the enhancement stream and the swirling exhaust gases intensifying mixing of exhaust gases with the ambient air, reducing the vertical compiling second speed-gas mixture in the central part of the vane apparatus is positioned vertically hollow cylinder to the outer cylindrical surface of which are attached guide vanes which the other ends are fastened its lower part to the annular support, fastened to the roof of the body of the locomotive over the vent motor branch pipe above the upper end of the hollow cylinder screen-jet blast deflector is placed with a diameter greater than the diameter of the hollow cylinder, which creates a horizontal circle
