Embodiment
As shown in Figure 2 and Figure 4, the blast furnace gas rough cleaner that the utility model provides comprises fly-ash separator cylindrical shell 5, is communicated with the raw gas inlet pipe 1 on described fly-ash separator cylindrical shell 5 top, is fixed on the center oviduct 4 of described fly-ash separator cylindrical shell 5 inside, is communicated with half purified gas escape pipe 3 of described center oviduct 4, the conical surface baffle plate 6 be fixed on described fly-ash separator cylindrical shell 5.Described raw gas inlet pipe 1 also can adopt horizontally disposed mode as Fig. 2 adopts to be obliquely installed.
Described rough cleaner also comprises flow deflector 2, and described center oviduct 4 is fixed on described fly-ash separator cylindrical shell 5 by described flow deflector 2.Described flow deflector 2 becomes 30-60 degree with horizontal plane, and such raw gas being arranged to enter described fly-ash separator cylindrical shell 5 can form the air-flow of rotation.The conical surface baffle plate 6 be provided with due to bottom again makes these flow slowing down enter described center oviduct 4.This mode makes air-flow in traveling process, easily depart from the dust of larger particles, is conducive to increasing dust removing effects.
In this embodiment, the best setting in a center of symmetry of described flow deflector 2.The fixation problem of described center oviduct 4 so not only can be made to be ensured, namely centrosymmetry arranges the middle that described center oviduct 4 can be made to be positioned at air-flow, and stressed easy balance ensures the stable problem of described center oviduct 4.Secondly, such air-flow being arranged to enter described fly-ash separator cylindrical shell 5 is convenient forms swirling eddy between described center oviduct 4 and described fly-ash separator cylindrical shell 5.
Arranging of described conical surface baffle plate 6 makes the gas velocity entering described center oviduct 4 be slowed down on the one hand, makes the dust fallen into bottom described fly-ash separator cylindrical shell 5 again can not be mixed into air-flow because of the drive of swirling eddy on the other hand.
The cone angle of described conical surface baffle plate 6 is 80-120 degree, and the cone angle beta of described center oviduct 4 is 8-12 degree.Show that this angle effect in this scope is best through repetition test.
Described blast furnace gas rough cleaner also comprises ash discharging hole 7, and described ash discharging hole 7 is arranged on the bottom of described fly-ash separator cylindrical shell 5.
The trend of air-flow in described blast furnace gas rough cleaner is: enter described fly-ash separator cylindrical shell 5 by the gas of described raw gas inlet pipe 1 along the pipe on described fly-ash separator cylindrical shell 5 top, the gas entered produces the air-flow of inclination under the drive of described flow deflector 2, the air-flow of described inclination moves to described conical surface baffle plate 6 place between described center oviduct 4 and described fly-ash separator cylindrical shell 5, carry out slowing down and break-in under the effect of described conical surface baffle plate 6, form swirling eddy and enter center oviduct 4, this slow down and break-in process in by air-flow larger particles dust disengaging.The air-flow rotating into described center oviduct 4 can depart from a part of dust more slowly further due to central gas stream.Last air motion, to the top of described center oviduct 4, is flowed out by the half purified gas escape pipe 3 being communicated with described center oviduct 4.The dust that dedusting obtains can be discharged by described ash discharging hole 7.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
