Abstract
The utility model provides an oxygen-enriched hot air combustion-supporting copper refining reverberatory furnace, which is provided with a furnace body; a combustor is arranged at the furnace head end of the furnace body; a flue duct is arranged at the tail end of the furnace body; a chimney is arranged at the tail end of the flue duct connected with a heat exchanger; a cloth bag dust collector is connected between the heat exchanger and the chimney through the flue duct; a combustion blower is arranged on one side of the flue duct and connected with the heat exchanger through a combustion air pipe; the combustion air pipe passes through the heat exchanger and is connected with the combustor; an oxygen pipe is arranged on the combustion air pipe between the heat exchanger and the combustor; and the oxygen pipe is connected with an oxygen replenishment device. Through the use of the oxygen-enriched hot air combustion-supporting copper refining reverberatory furnace, heat in flue gas is recovered, so that combusting air temperature is increased from original 30 to 40 degrees to 150 to 330 degrees, the oxygen content in oxygen-enriched hot air is 23 percent to 24 percent, the combustion-supporting effect is obvious, the feed melting area in the reverberatory furnace is extended, the feed melting time is reduced to 11 hours from 12 hours, the fuel consumption of copper is reduced by 5 to 10 cubic meters per ton, flue gas can enter into the cloth bag dust collector to be collected, and flue dust collection efficiency exceeds 99 percent, so that the environmental protection is remarkably improved.
Description
The (1) technical field: the utility model relates to smelting equipment, is the combustion-supporting Copper Refining Reverberatory Furnace of a kind of oxygen enrichment hot blast.
The (2) background technology: need combustion fuel in the production process of the fusing of copper refining reflection at present composition brass, the flue-gas temperature of generation is the 1200-1300 degree.Flue gas gets into flue, through the chimney emptying.Because flue-gas temperature is high, be difficult to capture dust in flue gas with bag collection, the unprocessed direct emptying of flue gas, dust in flue gas pollutes the environment.Heat content in the flue gas does not obtain utilizing yet, and this part heat wastes, and causes the energy consumption of copper refining production process high.
The (3) summary of the invention: the purpose of the utility model is improved above shortcoming exactly.Proposition can be reclaimed the heat in the flue gas, and combustion efficacy is improved, and has reduced the fuel consumption in the production process, improves the combustion-supporting Copper Refining Reverberatory Furnace of a kind of oxygen enrichment hot blast of environmental protection.
The combustion-supporting Copper Refining Reverberatory Furnace of the utility model oxygen enrichment hot blast has body of heater, and the burner end of body of heater is provided with burner; The tail end of body of heater is provided with flue, and the tail end of flue is provided with chimney, it is characterized in that: flue is connected with interchanger; Be connected with bagroom through flue between interchanger and the chimney; One side of flue is provided with the burning blower fan, and the burning blower fan is connected with interchanger through the burning airduct, and the airduct that burns passes interchanger and is connected with burner; Burning airduct between interchanger and the burner is provided with oxygen hose, and oxygen hose is connected with oxygen-distributing device.
The utility model is simple in structure, and is easy to use, reclaimed the heat in the flue gas; Make burning wind-warm syndrome degree bring up to the 150-330 degree from original 30-40 degree; The oxygen enrichment hot blast contains oxygen 23-24%, and combustion-supporting effect is extremely remarkable, and reverberatory furnace internalization material zone prolongs; The charging fusing activity duration was reduced to 11 hours from 12 hours, and fuel (Sweet natural gas) consumption is reduced 5-10m3/t copper.But 19.44 ten thousand yuan of 10,000 tons of copper cost savings of every production, flue gas can get into bagroom and capture flue gas, and dust arrestment rate surpasses 99%, has significantly improved environmental protection.
The (4) description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1-body of heater, 2-burner, 3-flue, 4-interchanger, 5-bagroom, 6-chimney, the 7-blower fan that burns, the 8-airduct that burns, 9-oxygen-distributing device, 10-oxygen hose.
The (5) embodiment:
In Fig. 1, the specific embodiments of the combustion-supporting Copper Refining Reverberatory Furnace of the utility model oxygen enrichment hot blast is: have body of heater 1, the burner end of body of heater 1 is provided with burner 2; The tail end of body of heater 1 is provided with flue 3, and the tail end of flue 3 is provided with chimney 6, and flue 3 is connected with interchanger 4; Be connected with bagroom 5 through flue 3 between interchanger 4 and the chimney 6; One side of flue 3 is provided with burning blower fan 7, and burning blower fan 7 is connected with interchanger 4 through burning airduct 8, and the airduct 8 that burns passes interchanger 4 and is connected with burner 2; Burning airduct 8 between interchanger 4 and the burner 2 is provided with oxygen hose 10, and oxygen hose 10 is connected with oxygen-distributing device 9.The flue gas that the reverberatory furnace burner produces gets into interchanger through flue; After lowering the temperature, flue gas gets into bagroom in interchanger; Flue gas gets into the chimney emptying after the bagroom dedusting.Burning wind has carried out heat exchange with flue gas in interchanger, improve temperature, changes into heat (burning) wind; The burning airduct of heat air delivery is communicated with oxygen hose, and oxygen gets in the hot blast mixed with it, obtains the oxygen enrichment hot blast, gets into burner combustion again.
