Circuit board etching waste liquid processing device

Patent No.: ZL201220004588.4

Application date: 2012.01.07

Announcement (announcement) date: 2012.09.05

Main technical features:

ü The treatment device includes an acid etching waste liquid preheater, an alkaline etching waste liquid preheater and a neutralization reactor for acid-base etching waste liquid

ü Acid etching waste liquid preheater adopts steam jet heating to save consumables and improve thermal efficiency, which solves the problem that stainless steel inner coil is not resistant to chloride ion corrosion.

ü Alkaline etching waste liquid adopts inner coil heating method to solve the problem that stainless steel inner coil is not resistant to acid corrosion.

ü The waste liquid reacts neutrally at the feed port, reducing the anti-corrosion requirements of the reactor and improving the reaction efficiency.

ü The device has simple structure, good technical effect, safety, environmental protection and practicality. It can be widely used in the recycling industry of circuit board etching waste liquid.
