Abstract:
A gas discharge device for discharging first and second gases from a paving vehicle to ambient air, the first gas flowing from a first gas source and the second gas flowing from a second gas source, the second gas having pressure pulsation of a first magnitude, the paving vehicle having fume removal system configured to evacuate paving material fumes from a location one of within the vehicle and proximal to the vehicle, the fume removal system having an outlet portion providing the first gas source, the first gas including paving material fumes and air, and an engine having an exhaust flow line providing the second gas source, the second gas including engine exhaust gases, the discharge device comprising:an elongated body connected to the vehicle and having a first inlet fluidly connected to the first gas source, a second inlet fluidly connected to the second gas source, an outlet fluidly communicable with ambient air, and an interior mixing chamber, the first and second inlets each being fluidly communicable with the mixing chamber such that the first and second gases flow into the mixing chamber when the first inlet is connected with the first gas source and the second inlet is connected with the second gas source, the body being configured to combine the first and second gases within the mixing chamber so as to form a combined gas having pressure pulsation of a second magnitude, the second pulsation magnitude being substantially lesser than the first pulsation magnitude, and to discharge the combined gas through the outlet to ambient air.
