The utility model content:
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of energy-saving circulation smelting furnace is provided, by structural design with two smelting furnace afterbody UNICOMs and a shared flue, can make twin furnace preheating furnace each other, realize UTILIZATION OF VESIDUAL HEAT IN, improve the finished product output capacity, reach the purpose of energy-saving and emission-reduction consumption reduction.
The technical solution of the utility model is achieved in that
Energy-saving circulation smelting furnace, body of heater is a tunnel structure, each single-unit furnace is that fuel inlet end, burner hearth, the stove tail of stove is that the end that stove links to each other with flue is formed by burner, it is characterized in that, body of heater is oppositely contacted by the shared stove tail that is connected by two single-unit furnaces of first, second and is formed, the floss hole of first stove is opened in the burner side of second stove, and the floss hole of second stove is opened in the burner side of first stove.
The flue of the flue of first stove and second stove converges common flue of formation.
The floss hole of first stove is provided with first stove floss hole gate, and the floss hole of second stove is provided with second stove floss hole gate.
First stove burner is provided with first stove fuel, fuel gas inlet, and second stove burner is provided with second stove fuel, fuel gas inlet.
The outside of first stove burner hearth is provided with first stove feed(raw material)inlet, and the outside of second stove burner hearth is provided with second stove feed(raw material)inlet.
The inboard of first stove burner hearth is provided with the outlet of first stove liquation, and the inboard of second stove burner hearth is provided with the outlet of second stove liquation.
Compared with prior art, the beneficial effects of the utility model are embodied in:
Because two stoves are preheating furnace each other, constantly smelt-formal transformation of preheating-smelting by two stoves, make full use of waste heat, not only shorten the duration of heat of half, save the huge energy, increase work efficiency greatly, and can reduce discharge of harmful gases such as CO2, SO2, simultaneously can improve the secondary metal output capacity, thereby reduce production costs greatly, improve the business economic benefit.
Description of drawings:
Fig. 1 is a plan structure schematic diagram of the present utility model.
Number in the figure: 1, first stove burner hearth, 1-1, first stove burner, 1-2, first stove fuel, fuel gas inlet, 1-3, first stove floss hole gate, 1-4, first stove floss hole, 1-5, first stove flue, 1-6, the outlet of first stove liquation, 1-7, first stove feed(raw material)inlet, 1-8, first stove liquation goes out port strobe, 2, second stove burner hearth, 2-1, second stove burner, 2-2, second stove fuel, fuel gas inlet, 2-3, second stove floss hole gate, 2-4, second stove floss hole, 2-5, second stove flue, 2-6, the outlet of second stove liquation, 2-7, second stove feed(raw material)inlet, 2-8, second stove liquation goes out port strobe, 3, shared stove tail, 4, common flue.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The specific embodiment:
Embodiment: referring to Fig. 1, the body of heater of present embodiment is oppositely contacted by the shared stove tail that is connected 3 by two single-unit furnaces of first, second and is formed, the floss hole 1-4 of first stove is opened in the burner side of second stove, the floss hole 2-4 of second stove is opened in the burner side of first stove, and the flue 1-5 of first stove and the flue 2-5 of second stove converge shared flue 4 of formation; The floss hole of first stove is provided with first stove floss hole gate 1-3, and the floss hole of second stove is provided with second stove floss hole gate 2-3; First stove burner 1-1 is provided with first stove fuel, fuel gas inlet 1-2, and second stove burner 2-1 is provided with second stove fuel, fuel gas inlet 2-2; The outside of first stove burner hearth 1 is provided with first stove feed(raw material)inlet 1-7, and the outside of second stove burner hearth 2 is provided with second stove feed(raw material)inlet 2-7; The inboard of first stove burner hearth is provided with first stove liquation outlet 1-6, and the inboard of second stove burner hearth is provided with second stove liquation outlet 2-6; The liquation outlet of first stove also is provided with first stove liquation and goes out port strobe 1-8, and the liquation outlet of second stove also is provided with second stove liquation and goes out port strobe 2-8.
When enabling the smelting of first stove, close second stove floss hole gate 2-3 earlier, open first stove floss hole gate 1-3, fuel such as combustion gas, coal dust sprays into the first stove from fuel, the fuel gas inlet 1-2 of first stove, the tail gas of first stove enters second stove burner hearth by shared stove tail 3 and feeds common flue 4 through first stove floss hole 1-4, this moment, the second stove carried out preheating as preheating furnace to the raw material in the second stove, and when the first stove was smelted end, the raw material in the second stove can be preheating to more than 600 degree.At this moment, open second stove floss hole gate 2-3 again, close first stove floss hole gate 1-3, fuel such as combustion gas, fine coal spray into the second stove from fuel, the fuel gas inlet 2-2 of second stove, and the second stove begins to smelt.Opening first stove liquation simultaneously goes out port strobe the molten metal of smelting good molten condition in the first stove is discharged, after discharging finishes in time by first stove feed(raw material)inlet 1-7 with raw materials such as the old metal first stove of packing into, the first stove utilizes the high-temperature flue gas of second stove that the raw material in the first stove is carried out preheating as preheating furnace at this moment.Because the smelting furnace exhaust temperature is high and contain a large amount of metallic dusts, tail gas is by preheating furnace the time, and not only raw material obtains preheating, waste heat obtains utilizing, and have considerable metallic dust precipitation to be trapped in the preheating furnace, thus can reduce the generation of flue stone, improve the output capacity of secondary metal.Such two stoves are preheating furnace each other, the continuous conversion of the smelting-preheating-smelting form by two stoves, can make each smelting furnace smelting cycle shorten half, increase work efficiency greatly, also save the energy accordingly greatly, reduce gas purgings such as CO2, SO2, alleviate the coal desulfurization processing pressure, can greatly improve secondary metal finished product output capacity simultaneously, thereby reduce production costs greatly, improve the business economic benefit.
