1. a many diesel engines washing tail gas silencing apparatus and a two way sealed device that uses in parallel is characterized in that being connected, carrying out synchronously the processing that smokeshade captured and reduced exhaust sound with the diesel engine exhaust of 1~

  • 6 parallel connection with a washing silencing apparatus;

    Being connected with the diesel engine exhaust of 1~

    6 parallel connection with a washing silencing apparatus is by a kind of two way sealed device, make the diesel engine when operation outlet pipe that is connected cut off tail gas and all enter the washing silencing apparatus with atmosphere, when not moving outlet pipe with wash the silencing apparatus partition and directly communicate with atmosphere;

    The processing of carrying out synchronously that smokeshade captures and reducing exhaust sound be by 250~

    450 ℃

    tail gas stream in the washing silencing apparatus when the fully moistening porous aggregate laminar surface of 50~

    70 ℃

    wash water, smokeshade more than 65% and tail gas heat quantity and noise waves kinetic energy are absorbed by liquid simultaneously, the water molecule that obtains energy becomes water vapour and is taken away by tail gas, exhaust temperature is reduced to below 80 ℃

    , volume shrinkage 40%~

    60%, density is increased to 1.0kg/m 3More than, flow velocity is reduced to below the 3.0m/s, and exhaust sound is reduced to OBSPL 51.3~

    81.9dB.
