Alkaline etching electrolysis recycling system and electrolysis recycling method

Abstract

The invention provides an alkaline etching electrolysis recycling system and an electrolysis recycling method. The recycling system comprises an electrolysis groove, a circulation groove and an adjustment groove, wherein the electrolysis groove is connected with a cooling water tower through a cooling water pipe; a waste liquid storage barrel is arranged on the upstream of the electrolysis groove;an etching production line is connected to the upstream of the waste liquid storage barrel; a recycled liquid storage barrel is arranged on the upstream of the circulation groove; an electrode platebase is arranged in the electrolysis groove and is fixedly connected with an electrode through a polar plate fixing screw; and a rectifier is arranged between the electrode and an electroplating powersupply. The recycling method comprises four steps of preparing, electrolyzing, extracting copper, and blending. According to the alkaline etching electrolysis recycling system and the electrolysis recycling method provided by the invention, the production line is connected with the recycling system, so that the continuous production of etching and electrolyzing is ensured, the safety is good, thealkaline etching electrolysis recycling system and the electrolysis recycling method are environmental-friendly without pollution, a large number of copper ions in the waste etching liquid can be effectively recycled, toxic substances in discharged water and discharged gas are reduced to the minimum, the production efficiency and the economic efficiency are good, and the production cost is low.

Description

technical field [0001] The invention relates to the technical field of fine chemical products, in particular to an alkaline etching electrolytic cycle regeneration system and an electrolytic cycle regeneration method. Background technique [0002] With the recovery of the electronics industry, the development of China's circuit board industry has also generally rebounded. According to the "2009-2012 China Printed Circuit Board Industry Development and Prospect Forecast Analysis Report", China will become the world's largest PCB industry base in recent years. It currently accounts for about 30% of the global market. At the same time, Suining, Sichuan is currently the "Southwest Circuit Board (PCB) Industry Manufacturing Base" approved by the state. With the presence of PCB industry giants such as Positronics and Foxconn Electronics in Sichuan and Chongqing, and the relocation of a large number of circuit board factories along the coast, the PCB industry will continue to grow....
