1. an acid copper chloride etching liquid electrolytic regeneration circulates and copper coin retrieving arrangement, it is characterized in that, comprise the electrolyzer, the auxiliary cylinder of etching, etching waste liquor collection cylinder, regenerated liquid collection cylinder and the emission-control equipment that utilize composite conductive high molecular film to be divided into cathodic area and positive column;

  • In described cathodic area, be provided with catholyte sheet, in described positive column, be provided with anode electrolysis sheet, in the auxiliary cylinder of described etching, be provided with air-dissolving apparatus;

    The waste liquid that etching cylinder produces is sent into the cathodic area of electrolyzer by etching waste liquor collection cylinder, the positive column of electrolyzer is provided with water outlet and air outlet, this water outlet is communicated with by the auxiliary cylinder of regenerated liquid collection cylinder and etching, the gas that this air outlet produces positive column passes in the auxiliary cylinder of etching by air-dissolving apparatus, the auxiliary cylinder of etching is communicated with etching cylinder, and the waste gas that the auxiliary cylinder of described etching produces is sent in emission-control equipment.
