Abstract
The utility model discloses an open hearth is smelted to heat accumulation formula for reclaimed copper, include and smelt the open hearth, and set up in the pipe of discharging fume of smelting the open hearth top, still include and discharge fume the combustion air heat exchanger of tub installation, and with the oxygen hose and the gas pipe of combustion air heat exchanger installation, and install in the premixing device of oxygen hose and gas pipe output, and be connected with the premixing device output, and with the regenerative burner who smelts the open hearth installation. The utility model discloses an open hearth is smelted to heat accumulation formula for reclaimed copper uses more energy -conservingly, and it has eliminated local high -temperature region, and the furnace temperature distributes evenly, improves to add the thermal mass, and extension stove refractory material life reduces gaseous CO2 emission of green house effect and NOx formation volume, uses environmental protection more.
Description
Technical field
The utility model relates to a kind of reclaimed copper production equipment, is specifically related to a kind of heat accumulating type melting open hearth for reclaimed copper, belongs to reclaimed copper production equipment technical field.
Background technology
Smelting enterprise of China and processing enterprise's scale constantly expand, and cause raw materials requirement to increase, imbalance between supply and demand is more and more outstanding.Domestic smelting enterprise production capacity is expanded rapidly, and smeltery more and more will depend on copper scrap for the demand of raw material; Copper scap resource copper scap is the raw material of reclaimed copper, and it derives from the every field such as production, circulation, consumption of society, is that a classification is many, the raw material of the copper of complicated component; Reclaimed copper treatment process process is complicated, and its apparatus for production line is more numerous and diverse, and wherein, existing reclaimed copper melting energy-saving effect is poor, and Melting Quality is not high enough, and body of heater is shorter for service life.
Utility model content
(1) technical problem that will solve
For solving the problem, the utility model proposes a kind of heat accumulating type melting open hearth for reclaimed copper, energy-saving and environmental protection, good product quality, and body of heater long service life.
(2) technical scheme
Heat accumulating type melting open hearth for reclaimed copper of the present utility model, comprises melting open hearth, and is arranged at the smoke exhaust pipe at melting open hearth top; Also comprise the combustion air heat exchanger installed with smoke exhaust pipe, and the oxygen hose installed with combustion air heat exchanger and Gas Pipe; And be installed on the pre-mixing apparatus of oxygen hose and Gas Pipe output; And be connected with pre-mixing apparatus output; And the heat-accumulating burner installed with melting open hearth.
As preferred embodiment, described combustion air heat exchanger smoke evacuation end is connected to smoke treated system.
Further, proportioning valve is provided with between described pre-mixing apparatus and heat-accumulating burner.
(3) beneficial effect
The utility model compared with prior art, heat accumulating type melting open hearth for reclaimed copper of the present utility model, use more energy-conservation, which obviate district of localized hyperthermia, furnace is even, improves heating quality, extends furnace refractories service life, reduce greenhouse gases CO2 discharge capacity and NOx generation amount, use environmental protection more.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
A kind of heat accumulating type melting open hearth for reclaimed copper as shown in Figure 1, comprises melting open hearth 1, and is arranged at the smoke exhaust pipe 2 at melting open hearth top; Also comprise the combustion air heat exchanger 3 installed with smoke exhaust pipe, and the oxygen hose 4 installed with combustion air heat exchanger and Gas Pipe 5; And be installed on the pre-mixing apparatus 6 of oxygen hose and Gas Pipe output; And be connected with pre-mixing apparatus output; And the heat-accumulating burner 7 installed with melting open hearth.
Described combustion air heat exchanger 3 end of discharging fume is connected to smoke treated system 8.
Proportioning valve 9 is provided with between described pre-mixing apparatus 6 and heat-accumulating burner 7.
Heat accumulating type melting open hearth for reclaimed copper of the present utility model, due to by heat exchanger by waste heat recovery most in flue gas, and by participate in burning medium belt melt down in, greatly reduce melting open hearth heat expenditure, energy-saving effect is obvious; During use, by the adjustment of pre-mixing apparatus and proportioning valve; Eliminate district of localized hyperthermia, furnace is even; Fuel burns under high-temperature low-oxygen concentration operating mode, is formed and do not stabilize the flame diffusion flame in stove, eliminates the district of localized hyperthermia stabilizing the flame generation; Flame is almost full of whole burner hearth, makes furnace temperature more even; Heat-accumulating burner makes the position of flame and furnace gas flow direction frequently change, and enhances furnace gas convection current, reduces dead angle in stove, also makes furnace temperature more even; Uniform furnace temperature make copper scrap melt heating evenly, reduce localized hyperthermia and oxygen-enriched environment to the volatilization of copper liquid and oxidation; District of furnace temperature all even elimination localized hyperthermia makes refractory material be heated evenly, and ensures that refractory material always works within the scope of rational serviceability temperature; Air was preheating to close to fire box temperature before entering burner hearth, made refractory material in stove alleviate heat and to shake impact; After conservation of fuel, corresponding CO2 discharge capacity also will reduce.Due to the elimination in district of localized hyperthermia, effectively reduce the growing amount of NOx.
Embodiment recited above is only be described preferred embodiment of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
