| 摘要 |
The present invention relates to a nozzle unit of a dry ice washing machine for dry ice snow induced injection. The nozzle unit comprises: a first liquefied carbonated gas input unit which inputs liquefied carbonated gas to a path inside a nozzle; a carrier gas input unit which inputs carrier gas into the path inside the nozzle; a first adiabatic expansion unit which adiabatically expands the liquefied carbonated gas, inputted to the path inside the nozzle through the first liquefied carbonated gas input unit, to generate dry ice snow; an eddy forming unit installed in the path inside the nozzle to enable at least a portion of the carrier gas, which transfers gas evaporated in the liquefied carbonated gas, or dry ice snow, to form an eddy; and a discharge unit which discharges the dry ice snow, passing the eddy forming unit, to an object to be washed. |
