Ceramic fiber filter tube forming process
The invention relates to a ceramic fiber filter tube forming process, which comprises the following steps: 1, preparing nascent ceramic fibers; 2, preparing a primary material of the ceramic fiber pipe body; 3, preparing nano particles; 4, uniformly coating the surface of the inner wall of the initial material of the ceramic fiber tube body with nano particles, and calcining at 450-500 DEG C for 4 hours to prepare the ceramic fiber tube body, and controlling the coating thickness to be 1-1.5 mm; 5, one end of the ceramic fiber pipe body being subjected to U-shaped end sealing, a flange being fixedly installed at the other end of the ceramic fiber pipe body, and manufacturing a ceramic fiber filter pipe with the length being 1 m; when the ceramic fiber tube body is used for waste gas treatment, particles in cooled dust-containing waste gas are adsorbed by the ceramic fiber tube body, emission of dust-containing particles is reduced, secondary pollution is avoided, in addition, the unique structure of the silicon dioxide nanotube can be used for treating the waste gas, on one hand, the waste gas is adsorbed, and on the other hand, the waste gas can be oxidized and decomposed only by providing an illumination condition.
本发明涉及陶瓷纤维滤管成型工艺，第一步、制备初生陶瓷纤维；第二步、制备陶瓷纤维管体初料；第三步、制备纳米粒子；第四步、将纳米粒子均匀涂覆在陶瓷纤维管体初料内壁表面，450‑500℃下煅烧4h，制得陶瓷纤维管体，控制涂覆厚度为1‑1.5mm；第五步、将陶瓷纤维管体一端进行U型封端，陶瓷纤维管体另一端固定安装法兰，制成长度为1m的陶瓷纤维滤管；用于废气处理时，冷却后的含尘废气中的颗粒被陶瓷纤维管体吸附，减少含尘颗粒的排放，避免造成二次污染，此外二氧化硅纳米管独特的结构能够对废气本身进行处理，一方面对其进行吸附，另一方面仅提供光照条件就能够对废气本身进行氧化分解。
