摘要： The present disclosure relates to a method for adjusting grouting parameters in preparation of a ceramic composite fiber-based catalytic filter tube, and a method and a device for preparing a ceramic composite fiber-based catalytic filter tube. In the present disclosure, a loading reference value of a slurry is determined by a fiber length, a pH value, and a solid phase content of the slurry, thus evaluating a performance value of the slurry; initial working parameters for preparation are determined by comparing the loading reference value of the slurry with a preset value. During the actual preparation, a grouting amount is introduced to conduct conversion check on a quality of the slurry, so as to ensure a grouting pressure and a grouting pressure holding time during the grouting.
