摘　　要：双氧水制备过程中的氢化及氧化工序均需采用热交换器进行加热或冷却,目前国内双氧水企业多采用可拆卸板式热交换器,但双氧水具有腐蚀性,常使可拆卸板式热交换器垫片处发生泄漏,造成停工、停产和一定的经济损失。因此,提出了以焊接板框式热交换器替代可拆卸板式热交换器的方案,并对焊接板框式热交换器的结构及工艺参数进行了设计。对双氧水制备装置中已投入使用的焊接板框式工作液/氢化液热交换器的应用验证表明,焊接板框式热交换器具有结构紧凑、占地面积小、耐腐蚀能力强、便于维修及运行成本降低等优势,在双氧水制备装置中具有广阔的应用前景。The hydrogenation and oxidation procedures in the preparation process of hydrogen peroxide need to adopt heat exchanger for heating or cooling. Most companies in China use frame plate heat exchanger at present. Because the hydrogen peroxide is corrosive, making the gasket of the frame plate heat exchanger leak, it will cause production shutdown and certain economic loss. Therefore,welding plate and frame heat exchanger is put forward to replace the frame plate heat exchanger, and the structure and the process parameters of welding plate and frame heat exchanger are designed. By verifying the working liquid/liquid hydrogen welding plate and frame type heat exchanger which has been put into use in hydrogen peroxide preparation device, it shows that the welding plate and frame heat exchanger, which has compact structure, less occupied area, corrosion resistant ability, easy maintenance and reducing running cost advantage, has broad plication prospects in the hydrogen peroxide industry.
