Abstract

In order to more accurately describe the change of the filtration efficiency of the granular bed filter using semi-coke as the filter medium during the whole filtering process, the effects of the apparent gas velocity, filter material thickness and filter material particle size on the filtration efficiency of the granular bed filter were investigated on a cold state experimental device, taking into account the changes in bed voidage, dust deposition on the filter material surface, and secondary entrainment, The mathematical model of unsteady filtration efficiency is derived theoretically, and the correction coefficient expression of the filtration coefficient in the particle bed filtration model is introduced as F(σ)=(1+bσ)n1(1-aσ)n2, fitting the experimental results under different operating conditions with Matlab programming software, and obtaining the values of characteristic parameters a and b. Within the scope of the experiment, the calculated value of the mathematical model is in good agreement with the experimental value.
