Electroplating effluent atmosphere concentration unit

Abstract

The invention discloses an electroplating effluent atmosphere concentration unit, comprising a rack, a liquid storage tank, a concentration tank, a heat exchanger, an air draft device and an electric cabinet, wherein the liquid storage tank is arranged on the rack, the concentration tank is arranged above the liquid storage tank and comprises a stuffing box and a defogging box; the defogging box is arranged above the stuffing box, a sprinkler body is arranged at the top end of the stuffing box, a packing layer is arranged below the sprinkler body and an air window is arranged at the bottom end of the stuffing box; the defogging box is communicated with the air draft device and the liquid storage tank is connected with the heat exchanger by a circulation pump; the heat exchanger is connected with the sprinkler body by a conduit provided with a temperature controller; the electroplating effluent atmosphere concentration unit has the characteristics of simple structure, small volume, high efficiency and more suitability for industrialized promotion.

Description

technical field [0001] The invention relates to an electroplating waste liquid treatment device, in particular to an electroplating waste liquid atmospheric concentration device for recycling the electroplating waste liquid containing heavy metals such as gold, silver, nickel, copper and chromium. Background technique [0002] The electroplating industry is an important processing industry in my country. At present, galvanizing, chrome plating, nickel plating and copper plating are mainly used, and they are concentrated in the industrial fields of machine manufacturing, light industry, electronics, aerospace and instrumentation. Electroplating processing is usually the The object to be plated is placed in the electrolytic tank containing the corresponding chemical electrolyte, and the surface of the object to be plated forms an electroplating layer after being energized. According to complete statistics, the national electroplating industry discharges as much as 400 million to...
