燃气环亚ag88经过长时间运行,不可避免的出现了水垢、锈蚀问题,环亚ag88形成水垢的主要原因是给水中带有硬度成份,经过高温、高压的不断蒸发浓缩以后,在炉内发生一系列的物理、化学反应,在受热面上形成坚硬、致密的水垢,导致换热效果降低且因垢下腐蚀因素,会导致环亚ag88水冷壁炉膛吸热减少,环亚ag88炉膛出口温度增加,使环亚ag88损失增加。同时水冷壁内结垢后使传热效果减少,有可能导致水冷壁管壁温度增加导致水冷壁爆管,影响热风炉安全运行。水垢是热风炉的“百害之首”,是引起热风炉事故的主要原因,其危害性主要表现在:浪费大量燃料:因为水垢的导热系数只有钢材的几十分之一,所以当受热面结垢后会使传热受阻,为了保持热风炉一定的出力,就必须提高火侧的温度,从而使向外辐射及排烟造成热损失。
After a long period of operation, scaling and rusting inevitably appear in the gas hot blast stove. The main reason for scaling formation in the hot blast stove is the hardness component in the feed water. After continuous evaporation and concentration at high temperature and high pressure, a series of physical and chemical reactions occur in the stove, forming a hard and compact scale on the heating surface, resulting in reduced heat transfer effect and corrosion under scaling. The factors will lead to the decrease of heat absorption in the water-cooled hearth of the hot blast stove, the increase of the outlet temperature of the hot blast stove, and the increase of the loss of the hot blast stove. At the same time, the scaling in the water wall reduces the heat transfer effect, which may lead to the increase of the wall temperature of the water wall and the bursting of the water wall, affecting the safe operation of the hot blast stove. Scale is the most harmful factor of hot-blast stove and the main cause of hot-blast stove accidents. Its harmfulness mainly manifests in: wasting a large amount of fuel: because the thermal conductivity of scale is only one tenth of that of steel, heat transfer will be hindered when scaling on the heating surface. In order to maintain a certain output of hot-blast stove, it is necessary to raise the temperature of the fire side, so as to radiate outward and exhaust smoke. Heat loss. 环亚ag88清洗步骤:一步:除垢清洗,在清洗槽循环水内按比例加入配置好的除垢清洗剂,进行热风炉清洗除垢,根据垢量多少确定清洗循环的时间和加入药剂多少,确认全部垢质清洗下来之后转入下一步清洗程序。第二步:清水清洗,将清洗设备和热风炉连接好后,要用清水循环清洗10分钟,检查系统状态,是否有泄漏,同时将浮锈清洗掉。第三步:剥离防腐清洗,按比例在清洗槽循环水内加入表面剥离剂和缓释剂,循环清洗20分钟,使垢质和清洗的各部件的分离,同时对没有结垢的物体表面 进行防腐处理,防止除垢清洗时清洗剂对清洗 部件产生腐蚀。第四步:钝化镀膜处理,加入钝化镀膜剂,对热风炉清洗系统进行钝化镀膜处理,防治管路和部件腐蚀以及新的锈垢生成。
The cleaning steps of gas hot-blast stove are as follows: one step: scale removal and cleaning, adding the disposed scale removal agent proportionally in the circulating water of the cleaning tank, cleaning and scale removal of the hot-blast stove, determining the cleaning cycle time and the amount of additives according to the amount of scale, confirming that all the scales have been cleaned down and then transferring to the next cleaning procedure. Step 2: Clean with clean water. After connecting the cleaning equipment with the hot blast stove, clean with clean water for 10 minutes. Check the system status, whether there is leakage, and clean the floating rust. The third step: peeling and anti-corrosion cleaning, adding surface peeling agent and slow-release agent in the circulating water of the cleaning tank in proportion, and cleaning for 20 minutes, so that the scales and cleaning components are separated. At the same time, anti-corrosion treatment is carried out on the surface of the non-scaling objects to prevent the cleaning agents from corroding the cleaning parts. Fourth step: passivation coating treatment, adding passivation coating agent, passivation coating treatment of hot blast stove cleaning system, prevention of pipeline and components corrosion and new rust scale formation.
