脱硫系统中常见的主要设备为吸收塔、烟道、烟囱、脱硫泵、增压风机等主要设备,湿法脱硫等工艺具有介质腐蚀性强、处理烟气温度高、SO2吸收液固体含量大、磨损性强、设备防腐蚀区域大、施工技术质量要求高、防腐蚀失效维修难等特点。
The main equipment for common absorption tower, flue, chimney, desulfurization pump, booster fan and other major equipment in desulfurization system, wet desulfurization process has strong corrosive medium, high temperature flue, SO2 absorption liquid solid content, wear resistance, corrosion prevention of equipment area, construction technology, high quality requirements anti corrosion failure repair difficult.
因此,该装置的腐蚀控制一直是影响装置长周期安全运行的重点问题之一。脱硫的防腐主要有以下几个方面:
Therefore, the corrosion control of the device is one of the key problems that affect the safe operation of the plant. Desulfurization anti-corrosion mainly in the following areas:
1、吸收塔、烟囱中的应用
1, absorption tower, chimney in the application
2、双流式塔盘防腐保护
2, double tray corrosion protection
某电厂在2010年对洗涤器升级时安装了新型双流式塔盘。在2011年的检验中表明,在塔盘较低表面上形成的沉积物区域下面,基底金属产生了较深的点蚀。用高压水将沉积物清洗干净,改变流量喷嘴试着控制结垢。
A power plant in 2010 to upgrade the scrubber installed a new dual flow tray. In 2011 that test, under the lower tray is formed on the surface of the sediment area, base metal of the deep pit. Clean the sediment with high pressure water, change the flow nozzle and try to control the fouling.
被腐蚀的区域现在需要进行涂层保护,以防止进一步的破坏。采用阿克-20防腐涂层为塔盘替换下来的陈旧的“碗状物”进行涂层,效果非常好。
The corroded area now needs to be coated to prevent further damage. By Chris -20 anticorrosion coating for tray replaced the old "bowl" coating, the effect is very good.
3、烟道脱硫防腐保护
3, flue desulfurization anti-corrosion protection
研发新阴极防腐系统,可用于燃烧系统的废气处理或者空气污染控制设施的保护–有效控制(电流控制)高温/极酸腐蚀环境(150?C,pH-2)薄涂层解决方案。
The development of new cathodic protection system, can be used to effectively control the protection, exhaust gas treatment or air pollution control facilities in the combustion system (current control) / very high ambient temperature (150 degrees C acid corrosion, pH-2) thin coating solution.
