Method for preparing industrial high-temperature flue gas filtering pipe from ceramic-based composite material
The invention provides a method for preparing an industrial high-temperature flue gas filtering pipe from a ceramic-based composite material. The method comprises the following steps: mixing aluminumoxide powder, glass fibers, a pore forming agent and carboxymethyl cellulose, carrying out stirring to obtain a dry material, adding water to form a wet material, conducting repeated extruding to forma muddy material, performing aging, conducting extrusion to obtain a ceramic blank pipe, coating the periphery of the pipe wall with an inorganic film, performing drying, conducting firing at a hightemperature in a kiln, and carrying out cooling to obtain the ceramic pipe. The method provided by the invention can be used for preparing the large-pipe-diameter industrial high-temperature flue gasfiltering pipe, and the obtained ceramic pipe is low in filtering resistance, high in efficiency, good in high-temperature resistance, good in folding resistance, durable in use and convenient to install, can be repeatedly used through back flushing and ash removal after usage of the pipe for a period of time, and is convenient to popularize and apply.
本发明提出一种陶瓷基复合材料制备工业高温烟气过滤管道的方法，所述工业高温烟气过滤管道是将氧化铝粉末、玻璃纤维、造孔剂和羧甲基纤维素混合搅拌成干料，然后添加水形成湿料，接着反复挤出形成泥状料并陈腐处理，再挤出得到陶瓷生坯管材，接着在管壁四周涂覆无机膜并干燥，最后通过窑炉高温烧成、冷却而制得。本发明提供的方法能够制备大管径工业高温烟气过滤管道，所得陶瓷管的过滤阻力低、效率快，耐高温性好，耐折性好，使用持久，安装方便，而且使用一段时间后能进行反吹清灰后重复利用，便于推广应用。
