摘　　要：双氧水是纸浆漂白工艺中常用的漂剂,但其化学性质不稳定,使用和储存都具有一定风险。橙氧科技的双氧水电解生产系统提供了一种绿色、方便,可持续的双氧水使用方案。整套系统采用电化学原理,仅需供应水、电、氧气即可生产低浓度的碱性双氧水,能直接应用于ECF漂白工艺。该设备在云景林纸1#制浆生产线漂白段成功完成中试生产,其中双氧水的直接生产成本仅1053元/t(浓度50%),与外购双氧水价格相比非常具有优势。Hydrogen peroxide is a common bleaching agent in pulp bleaching process,but its chemical properties are unstable,and its use and storage have certain risks.Hydrogen peroxide electrolytic generation system of Cheng Yang Tech providing a safe,green and sustainable industry case.This hydrogen peroxide electrolysis system applies electrochemical principle and can convert water,oxygen and electricity into low-concentration alkaline hydrogen peroxide,which can be directly applied to ECF bleaching process.The equipment successfully pilot production in the bleaching section of No.1 pulping line in Yunnan Yunjing Forestry and Pulp Co.,where the direct production cost of hydrogen peroxide is only 1053 yuan/ton(concentration 50%),which is very advantageous compared with the price of outsourced hydrogen peroxide.
