空气预热器的污垢的清洗方法
空气预热器的污垢中含有较多的钙、镁离子等物质,用一般的清洁剂很难清洗干净,需要采用特殊配置的碳酸盐溶液进行清洗。
Air preheater dirt contains more calcium, magnesium ions, such as material, using general cleaners are hard to clean the special configuration of carbonate solution need to be used for cleaning.
将碳酸盐溶液用毛巾蘸取少量,涂抹于空气预热器上有污垢的地方,来回进行擦拭,一段时间以后污垢自然就会消除。
Will dip in with towel carbonate solution, a little amount daub is on the air preheater with dirt, back and forth to wipe, after a period of time will eliminate dirt nature.
采用机械清洗的方式,机械清洗相较于上面的化学清洗来说更加安全可靠,不会产生残余物质。
With the method of mechanical cleaning, mechanical cleaning compared to the above is more safe and reliable chemical cleaning, won't produce residual material.
一般使用高压水进行清洗,利用高压水的压力对空气预热器的表面进行强力冲刷,使得污垢自行脱落,再使用抹布蘸取清水轻轻的擦拭干净即可。
Generally use high pressure water cleaning, the use of high pressure water pressure to strong erosion of the surface of the air preheater, the dirt to fall off,高密搪瓷管空气预热器, again use dip in with dishcloth take gently wipe clean it with clean water.
搪瓷管空气预热器如何做到解决了堵灰现象
目前,无论是工业锅炉还是电站锅炉,普遍存在着空气预热器低温腐蚀和堵灰现象,直接影响着锅炉及机组的安全运行和经济运行,特别是燃用高硫分煤种时问题就更加严重。
当前,很多电厂因空气预热器低温腐蚀和堵灰只能被动停炉维修更换,或为了避免低温腐蚀和堵灰,不惜提高锅炉的排烟温度,降低锅炉热效率。据测算,锅炉排烟温度每提高10℃,锅炉热效率就要下降1%左右,搪瓷管空气预热器厂家,从而造成大量的能源损失。
搪瓷管式空气预热器在预热器烟气进口烧制一种高耐磨搪瓷**涂层,取消了金属套管,加大了空气流通面积,降低了烟气流速,从而使磨损较为减轻.同时在烟气出口处烧制搪瓷涂层,搪瓷管空气预热器,解决低温腐蚀,而且由于搪瓷表面光滑,不容易产生积灰,减少预热器堵塞。
