洁净高温气体用陶瓷过滤管制备方法
摘要：
本发明涉及一种陶瓷过滤管制备方法，具体地说是涉及一种用于煤炭气化发电领域的洁净高温气体用陶瓷过滤管及制备方法。本发明通过下述技术方案予以实现：本发明洁净高温气体用陶瓷过滤管制备流程为：制作氧化物液相烧结剂→制作以SiC粒子为主要微观结构载体的陶瓷过滤管→制作莫来石纤维膜→涂膜→烧结制得陶瓷过滤管。本发明有如下有益效果：本发明利用氧化物形成粒子结合部以外作为过滤管使用时气体通道的空间，气孔内不存在多余的烧结助剂，气孔确保有气体通过率的空间；可保持结合相的机械强度、耐热性、化学稳定性，液相形成容易，本发明膜的强度、透气率和完整性均符合要求。本发明洁净气体高温陶瓷过滤管制备容易，成本低，可广泛应用于煤炭气化发电等方面的高温高性能的气体过滤。
摘要（英）：

The present invention relates to preparation of filtering ceramic tube, and is especially one kind of filtering ceramic tube for purifying high temperature gas in coal gasifying power generating field and its preparation process. The preparation process of the filtering ceramic tube includes the steps of: preparing liquid phase oxide sintering agent, preparing filtering ceramic tube with SiC particles as the main micro structure carrier, making mullite fiber film, coating film and sintering to obtain filtering ceramic tube product. The present invention has gas passage outside the oxide particle, no residual sintering assistant to ensure the gas passing rate, high mechanism strength of the combined phase, high heat resistance, high chemical stability, easy liquid phase formation, high strength, gas penetrating rate and integrality of the film.
