step (1): under the drive of a traveling device (D), when the mobile dust hood vehicle device is close to a dust removal station, a roller set (I) simultaneously travels on a flange guide rail (F), the flange guide rail (F) has different thicknesses, when the mobile dust hood vehicle device is close to the dust removal station, the thickness of the guide rail (F) is changed, and the roller set (I) is still tightly attached to the surface of the guide rail (F) under the action of a spring device (H), so that an elastic telescopic air pipe flange (C2) is axially far away from a mobile end air pipe flange (C1) and is tightly abutted to one end of a fixed end air pipe flange (C3) of a dust removal system, and sealing is realized; the dust removal device is used for collecting flue gas dust generated by the dust removal station through the cover body (A) and then sending the collected flue gas dust into a dust removal system for dust removal treatment;
step (2): when keeping away from the dust removal station, running gear (D) drive remove the walking of dust excluding hood car device, and roller train (I) walks on flange guide rail (F) simultaneously, and flange guide rail (F) thickness changes for spring assembly (E) compression makes flexible tuber pipe flange (C2) axial be close to and removes end tuber pipe flange (C1), no longer contacts with stiff end tuber pipe flange (C3).
