Title: Innovations by Xinxin Yang in Lead Oxide Recycling

Introduction

Xinxin Yang is an accomplished inventor based in Changxing, China. He has made significant contributions to the field of recycling, particularly in the recovery of lead oxide from waste materials. With a total of two patents to his name, Yang's work focuses on methods that enhance the efficiency and sustainability of lead recycling processes.

Latest Patents

Yang's latest patents include a method for recycling lead oxide-containing waste material. This innovative method involves several steps: first, the lead oxide-containing waste material is contacted with a desulphurizer under specific reaction conditions, followed by solid-liquid separation to obtain a filtrate and filtration residue. The filtration residue is then subjected to a conversion reaction at temperatures between 350-750°C to convert lead-containing components into lead oxide. The process continues with the product being treated with an alkaline solution to dissolve the PbO, leading to the crystallization of PbO crystals. This method notably reduces energy consumption.

Another significant patent by Yang is a method for directly recovering lead oxide used for lead-acid battery cathodes from waste lead paste. This method also begins with contacting waste lead paste with a barium-containing desulphurizer, followed by solid-liquid separation. The filtration residue undergoes a conversion reaction at similar temperatures to recover lead oxide. This approach not only decreases recovery costs and energy consumption but also improves the comprehensive utilization of waste lead paste.
