Gas-liquid separator, exhaust cleaner or air cleaner using the separator, and sterilizing air cleaner

摘要

A gas-liquid separator of one aspect of the invention comprises; an inflow barrel; a main cylindrical barrel on downstream of the inflow barrel, which has an inner barrel duct and is constructed to induce rotational momentum on to-be cleaned gas having flown in from the inflow barrel; a plurality of subordinate cylindrical barrels that have diameters smaller than that of the main cylindrical barrel and are serially connected as adjoined to downstream end of the main cylindrical barrel; a connector cylindrical barrel that has diameter smaller than those of the subordinate cylindrical barrels and connects inside spaces of the subordinate cylindrical barrels; and liquid receivers on beneath of the subordinate cylindrical barrels; and an outflow barrel at downstream end of the series of the subordinate cylindrical barrels.
