摘要: 选择性催化还原(SCR)高灰型布置脱硝装置中,催化剂长期经受烟尘的冲刷,催化剂的抗磨损强度关系到催化剂的使用性能。现有行业标准中蜂窝式催化剂的磨损强度试验方法为石英砂法,平板式催化剂的磨损强度试验方法为研磨法。为进行比较,对不同催化剂生产厂家生产的平板式催化剂分别采用研磨法和石英砂法进行了催化剂的磨损强度试验。结果表明:结合2种试验方法来综合评判平板式催化剂的抗磨损特性更具实际指导意义;试验风速对平板式催化剂石英砂加速磨损试验结果的影响较大,实际操作中应适当选择。

Abstract: In the high-ash-type selective catalyst reduction (SCR) denitration device, the catalyst is subjected to dust sweeping, which may affect the abrasion resistance of the catalyst and deteriorate the catalyst performance. In the current standard, the silica sand abrasion method is applied for the abrasion resistance test, while the grinding method is used for plate catalyst testing. For comparison, the abrasion resistance test on the plate catalysts produced by different companies is conducted by virtue of the silica sand abrasion method and the grinding abrasion method, respectively. The results show that it is more reasonable to determine the catalyst abrasion resistance performance jointly by the two methods. In addition, the wind velocity of the silica sand abrasion method has greater influence on the test result such that it should be tuned appropriately in practice.
