Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings:
As shown in Figure 1, small-sized air heating furnace deashing device, including hot-blast stove, it is equipped at the exhanst gas outlet 10 of hot-blast stove clear Apparatus for ash, the deashing device include shell 14, and 14 both ends of shell are respectively equipped with air inlet 18 and air outlet 17, are set in shell 14 Have a blast cap 15 coordinated with air inlet 18,15 front end of blast cap is equipped with removable filter partition board 16 in shell 14, the filtering every Plate 16 is equipped with hole, is equipped with thin wire gauze 19 close to the side of air outlet 17 on filter septum 16.
As depicted in figs. 1 and 2, hot-blast stove includes furnace body 3, is equipped with liner 7 in furnace body 3,7 lower section of liner be equipped with fire grate and into Material mouth 12 is equipped with heat exchange chamber 5 between furnace body 3 and liner 7, heat exchange chamber 5 is connect with 7 top of liner, and 5 lower section of heat exchange chamber is set There are air inlet 2,7 lower section of liner to be equipped with gas outlet 9, flue gas heat exchange chamber A13, heat exchange chamber are equipped between heat exchange chamber 5 and liner 7 It is equipped with flue gas heat exchange chamber B6 between 5 and furnace body 3, is connected to the tops flue gas heat exchange chamber B6 above flue gas heat exchange chamber A13, flue gas heat exchange Exhanst gas outlet 10 is equipped with below chamber B6;3 inside of furnace body and 5 outside of heat exchange chamber are respectively equipped with the annular wind resistance baffle plates being staggered 4, annular wind resistance baffle plates 4 coordinate with flue gas heat exchange chamber B6;Flue 8 is equipped in liner 7, flue 8 is connected to flue gas heat exchange chamber B6.
