用于砖瓦行业的风闸、闸门、排潮抽烟风机、哈风座、哈风帽等使用环境是极其恶劣简陋的.一般中小型砖瓦厂生产年耗煤大多数在1000t以上.即每天耗煤5～30t左右,这些煤在燃烧中产生大量的CO、CO_2、SO_2,夹带坯体和地下烟道、哈风道所产生的水蒸气,形成硫酸、亚硫酸、碳酸等酸雾烟气.坯体焙烧温度在930～980℃.风闸、闸门、风机、哈风帽等因其使用位置不同及窑体性能不同,其环境温度不同,一般在80～300℃.这些大量的湿度大、温度高的烟气酸雾对这些设备有很强的腐蚀作用,往往使用不到一年就被腐蚀坏.曾风行一时的玻璃钢防腐技术,由于排潮抽烟风机日夜连续在高温高湿酸雾环境中高速运转,风机叶轮使用不到几个月的时间,玻璃钢就剥离、翘曲、转子叶片就被腐蚀坏.
For the brick and tile industry, the use of wind gates, sluice gates, smoke evacuation fans, Hafeng seats, Harbin bonnets and other use environment is extremely harsh and simple. The average annual production of coal in small and medium-sized brick and tile factories is over 1000t. About 5 to 30 tons of coal, these coals produce a large amount of CO, CO 2 , and SO 2 in the combustion, entraining the water vapor generated by the green body and the underground flue, Harbin, and forming acid mist gas such as sulfuric acid, sulfurous acid, and carbonic acid. The blank baking temperature is between 930 and 980°C. The dampers, gates, fans, and bonnets are different because of their different locations and the performance of the kiln. The ambient temperature is different, generally 80 to 300°C. These large amounts of humidity and temperature High smoke mist has a strong corrosive effect on these devices, and is often corroded in less than one year. The prevailing glass steel anticorrosive technology was used because of the high temperature, high humidity, and humid fog environment during the day and night. At high speeds, fan impellers are used for less than a few months. FRP peels, warps, and rotor blades are corroded.
