US Patent 7976612 Droplet removing device and method in plasma generator

A device for removing droplets in a plasma generator including a tubular traveling passage through which plasma and droplets travel under mixed state is formed, an aperture having a passing hole at an eccentric position is provided in the tubular traveling passage, and a magnetic field generator passing the plasma through the eccentric passing hole of the aperture arranged on an outer circumference of the tubular traveling passage. The plasma further passes through the eccentric passing hole of the aperture after being bent in the tubular traveling passage by a magnetic field generated from the magnetic field generator and the droplets are removed by colliding against the wall face of the aperture at the time of bending.
