Embodiment
The present invention is elaborated with reference to Fig. 1.
Embodiment one：
As shown in figure 1, a kind of electric furnace of hot tail gas dust arrester, including electric furnace body 1, the bottom of electric furnace body 1
Air outlet 14 is connected with cyclone dust collectors 2, and the discharge pipe a13 of the cyclone dust collectors 2 is connected with water-bath impact dust remover, shown
The discharge pipe b12 of water-bath impact dust remover is connected with sack cleaner 10, and the bottom of cyclone dust collectors 2 is provided with dust collect plant 3,
The discharge pipe b12 is provided with ventilation pump 11, and the sack cleaner 10 is provided with valve 9.
Conventional electricity, due to being limited by filter cloth heatproof condition, removes when cleaning equipment uses sack cleaner into cloth bag
Dirt device flue-gas temperature should not be too high.
In the present embodiment, flue dust caused by electric furnace body 1 enters in cyclone dust collectors 2 through air outlet 14, the powder of bulky grain
Dirt is settled down in cyclone dust collectors 2 in the dust collect plant 3 of lower section, and flue dust enters from the discharge pipe a13 at the top of cyclone dust collectors 2
In wet dust collector, the dust of larger particles is stayed in wet dust collector, and flue dust enters sack cleaner 10 from discharge pipe b12
Interior, discharge pipe b12 is used for the temperature for introducing cold air reduction flue dust, prevents the too high cloth bag 8 for influenceing sack cleaner 10 of temperature.
By the mode of 3-stage dust-removal, the sack cleaner for solving the problems, such as conventional electric furnace is vulnerable to the limitation of filter cloth heatproof condition, together
When it is simple in construction, operating cost is low, good dedusting effect.
