Embodiment Construction
[0028] The following is attached Figure 1-4 The application is described in further detail.
[0029] The embodiment of the present application discloses a system for recovering micro-silicon fume from submerged arc furnace flue gas.
[0030] refer to figure 1 , a micro-silicon fume recovery system for submerged arc furnace flue gas, including a dust collection assembly 1, a recovery assembly 2 arranged on one side of the dust collection assembly 1, and a collection assembly 3 arranged below the dust collection assembly 1, which is placed on the submerged arc furnace. When the ore is smelted, the flue gas and microsilica powder generated enter the dust collection component 1, the recovery component 2 recovers the microsilica powder in the dust collection component 1, and the collection component 3 collects the microsilica powder recovered by the recovery machine component , in order to facilitate the recovery of micro-silica fume while reducing the secondary pollution of mic...
