Buffer to install on hopper 1 and weigh pressure head 2 and sealing valve 3, it is the weight for examining charge that it, which acts on one, and two be as slow
Slug storehouse.
It is 12-15 to expect lattice 7, for furnace charge to be evenly distributed in multiple material lattice 7 in pre-heating cabin.
The coal gas that the hot gas of interior furnace charge is produced using the mineral hot furnace itself reclaimed, air coefficient during burning<1, to keep away
Exempt from material to aoxidize.The thermal current of generation falls 15 access dedusters 13 by dust removing tube and purified, and 2/3 gas is by following after purification
Ring blower fan 12 sends into burner 10 as the gaseous mixture of regulation temperature, and 1/3 gas is emptied by discharge blower fan 14.The heat in material lattice 7
Air-flow is mixed into set point of temperature (500~550 DEG C) with the pre-heating cabin flue gas reclaimed, and hot gas flows up to add in pre-heating cabin
The descending furnace charge of heat.Furnace charge after preheating is homogeneously added into mineral hot furnace by many 12-15 roots feeding chutes 16.
The utility model has the advantage of realize the preheating of raw material by mineral hot furnace self produced gas and flue gas heat, realize one
The multiple tremie pipes of the individual pre- hot aggregate bin correspondence of furnace roof, substitute traditional multiple annular feed bin arrangements of furnace roof, and make full use of ore deposit
The heat energy of hot stove self produced gas and flue gas, is preheated to raw material, and the resistance in stove is stabilized by preheating, reduces smelting electricity
Consumption, improves the content of CO in mineral hot furnace gas, to production operation, smelts safe be highly profitable.
