Dust removal and desulfurization integrated silicon nitride porous ceramic and preparation method thereof
In order to solve the problem that the production cost is increased due to multi-step operation of desulfurization and dust removal in the prior art, the invention provides a dust removal and desulfurization integrated silicon nitride porous ceramic and a preparation method thereof. A desulfurization catalyst is loaded on the surface of porous ceramic in a dipping or spraying mode; the reaction raw materials comprise, by mass, 100 parts of rice husks, 10-20 parts of silicon nitride, 14-20 parts of a sintering aid, 1-10 parts of a pore forming agent and 6-10 parts of low-temperature molten glass powder; wherein the rice husks are soaked in diluted hydrochloric acid with the volume fraction of 8-12% for 20-50 days, and are boiled in diluted hydrochloric acid with the volume fraction of 8-12% for 10-30 minutes, then are cooled to room temperature and boiled again, and the steps are repeated for 3-5 times and finally the rice husks are dried.
为解决现有技术中脱硫除尘多步操作、增加生产成本的问题，本发明提供一种除尘脱硫一体化的氮化硅多孔陶瓷及其制备方法，除尘脱硫一体化的氮化硅多孔陶瓷，反应原料经挤出成型后烧结得到多孔陶瓷，通过浸渍或喷涂的方式将脱硫催化剂负载在多孔陶瓷表面，所述反应原料按质量份数配比由100份稻壳、10‑20份氮化硅、14‑20份烧结助剂、1‑10份造孔剂和6‑10份低温玻璃熔融粉组成，其中稻壳是在体积分数为8‑12%的稀盐酸中浸泡20‑50天后，在体积分数为8‑12%的稀盐酸中煮沸10‑30min，冷却至室温后再次煮沸，重复3‑5次后烘干得到。
