Problems solved by technology

However, the limited demand of the wastewater treatment station cannot completely consume the produced ferric chloride liquid, so it is difficult to deal with the excess ferric chloride. For this reason, it is necessary to develop a chlorine absorption treatment system device, which can neither produce other products and absorb chlorine gas

Abstract

The invention discloses chlorine treatment equipment of an acidic etching solution recovery system, a method, a control system and a control method. The design key points of the design include: a dissolution absorption cylinder (1), a ferrous chloride absorption device (2), a liquid alkali washing tower (3), a chlorine gas pipeline (6), a first jet device (7), a first gas pipeline (9), a second gas pipeline (10), a ferrous chloride regeneration device (4), a vacuum volatilization device (5), and a second jet device (14). The invention aims to provide the chlorine treatment equipment of an acidic etching solution recovery system, the method, the control system and the control method, and can effectively treat chlorine.

Description

technical field [0001] The present invention relates to the field of etching production line, and more specifically, relates to a chlorine gas treatment equipment, method, control system and control method of an acid etching solution recovery system. Background technique [0002] With the rapid development of the acid etching solution copper recovery and recycling industry, more and more PCB companies have installed etching solution copper recovery and regeneration equipment. During the operation of the equipment, the chlorine gas produced by electrolysis is absorbed by the etching solution in the dissolution and absorption cylinder. Due to the limited absorption of etching solution, some chlorine gas is still discharged after treatment. Almost all enterprises use iron absorption equipment to add iron to react with chlorine gas, and then pass through a set of liquid alkali absorption towers for treatment to meet the discharge standards. Iron absorption equipment is used to ad...
