[0020] In the application, in the process of flue gas dust removal, the flue gas is directly delivered to the spiral plate 10 through the air inlet pipe 4, and then the spiral acceleration of the spiral plate 10 realizes the centrifugation of the flue gas. Larger particulate matters are thrown on the inner wall of the shell 1 by centrifugation and slide down along the inclined inner wall of the shell 1 into the dust collecting box 2, so that the separation of large particles is realized.

In the process of conveying the flue gas upward on the spiral from the lower side to the upper side, the flue gas is first accelerated and then decelerated. By arranging friction lines on the sidewall of the second conical block 11, the small particles in the flue gas are charged by friction when the flue gas reaches the second conical block 11 on the upper end.
