[0002] Application No. 202222613698.7 discloses a reactor for wet purification of gold. During the wet purification process of gold, chemical reactions will occur between gold and aqua regia, which will produce toxic gases and nitrogen oxides. If these toxic gases and nitrogen oxides are not treated, they will evaporate into the air after the reactor is opened, endangering the health of the workers.
