Abstract
The utility model discloses the energy-saving device of the smelting furnace for regenerated nonferrous metal, comprising a housing (7), the upper side of which is provided with a flue gas discharge outlet (10); the inner part of the housing (7) is provided with a drying tunnel (6) which is obliquely arranged; the inlet of the drying tunnel (6) is higher than the outlet; a feeding gate (11) is arranged on the inlet of the drying tunnel; a discharge moveable baffle is arranged on the outlet of the drying tunnel; a flue gas inlet is arranged on the housing (7) at the lower side of the drying tunnel outlet; the housing (7) corresponding to the drying tunnel outlet and the flue gas inlet is provided with a suction hood (4), the outlet of which corresponds to a melting furnace (1). After adopting the structure, the energy-saving device of the smelting furnace for the regenerated nonferrous metal solves the problems that the smoke prevention and dust removing effects of the environmental protection equipment are poor, and the operating cost of the equipment is large, and the energy-saving device of the smelting furnace for the regenerated nonferrous metal has the advantages of simple and reasonable structure, high energy utilization, good yield, favorable comprehensive utilization benefit, etc.
Description
Technical field
The utility model relates to a kind of and the matching used auxiliary equipment of secondary nonferrous metal smelting furnace, the energy-conserving product of utilization of particularly a kind of secondary nonferrous metal smelting furnace residual heat integrative and control of dust dedusting.
Background technology
At present, the secondary nonferrous metal smelting furnace can be divided into crucible furnace, emission stove and electric furnace by function, and they can produce a large amount of flue dust and toxic gas in fusion process; In order to eliminate flue dust and toxic gas, clearly regulation has been made by government department, has formulated discharge standard; For this reason, most of producers have dropped into a large amount of funds and have been equipped with environmental protection equipment in order to reach discharging standards; Because existing environmental protection equipment smoke medicining dust-removing effect is poor, the equipment operating cost is big, the enterprise less concerning scale, that benefit is relatively poor, environmental protection equipment transformation or put into operation and all will increase the weight of the burden of enterprise greatly, most of environmental protection equipments are in inactive or partly stop half-open position, cause environmental protection equipment to establish, do not have due effect just as need.How developing a kind of can being in operation and produce the environment-friendly products of economic benefit, has been an emphasis research topic of government, institute and producer.
Summary of the invention
For overcoming the above-mentioned disadvantage that existing secondary nonferrous metal smelting furnace environmental protection equipment exists, problem to be solved in the utility model provide a kind of simple and reasonable, fuel input is few, go out the rate height, secondary nonferrous metal smelting furnace energy-saving appliance that comprehensive utilization benefit is good.The technical scheme that its technical problem that solves the utility model adopts comprises housing, the housing top is provided with the fume emission mouth, the drying tunnel that is obliquely installed is housed in the described housing, the import of drying tunnel is higher than outlet, in the drying tunnel import feeding gate is housed, in the drying tunnel outlet discharging sideboard is housed, on the housing below the drying tunnel outlet, be provided with gas approach, with on drying tunnel outlet and the gas approach corresponding shell suspended hood is housed, suspended hood exports corresponding with smelting furnace.
For the ease of the drying tunnel heating, the air inlet fire door is housed on the described gas approach, close the air inlet fire door, the flue gas of smelting furnace can make the drying tunnel temperature fast rise directly by discharging behind the drying tunnel.
Be provided with slide plate in the described suspended hood, the bottom of slide plate and drying tunnel outlet is connected, and can control the feed location of smelting furnace and prevents to splash.
For the ease of the cleaning lime-ash, described lower part of frame is provided with the ash discharge cinder notch, and the ash discharge cinder notch is provided with out the lime-ash door.
In order to discharge the drying tunnel flue gas, the top of described drying tunnel is provided with the drying tunnel exhaust outlet.
In order to improve dust removing effects, keeping off grey flap near being equipped with on the housing of fume emission mouth.
For the ease of reinforced, and be fixed with charging deck on the drying tunnel import corresponding shell.
After adopting said structure, mainly contain following several respects advantage, the one, the utility model can be used as primary dust removing device and the supporting use of original cleaner, and smoke medicining dust-removing effect is more; The 2nd, make full use of fume afterheat, the material in the drying tunnel is carried out preheating, temperature of charge can be brought up to more than 200 ℃ by original room temperature, dwindles the temperature difference between material and the smelting furnace, and fuel input can reduce 1/3rd; The 3rd, help the state more stably that remains on of temperature of smelting furnace, reduce material oxidation and evaporation in the fusion process, go out rate and can improve more than 2%; Solved the problem that the environmental protection equipment smoke medicining dust-removing effect is poor, the equipment operating cost is big; Have simple and reasonable, energy utilization rate is high, go out advantages such as rate is good, comprehensive utilization benefit is good.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Shown in Figure 1, specific embodiments for a kind of secondary nonferrous metal of the utility model smelting furnace energy-saving appliance, it comprises housing 7, housing 7 tops are provided with fume emission mouth 10, keeping off grey flap 9 near being equipped with on the housing 7 of fume emission mouth 10, the drying tunnel 6 that is obliquely installed is housed in the described housing 7, the import of drying tunnel 6 is higher than outlet, feeding gate 11 is housed in the drying tunnel import, with be fixed with charging deck 12 on the drying tunnel import corresponding shell 7, in the drying tunnel outlet discharging sideboard 5 is housed, discharging sideboard 5 can be divided into stuffy and ventilative two kinds, design as the case may be, the top of drying tunnel 6 is provided with drying tunnel exhaust 8, the gas in the discharging drying tunnel 6, on the housing 7 below the drying tunnel outlet, be provided with gas approach, air inlet fire door 3 is housed on the gas approach, and on drying tunnel outlet and the gas approach corresponding shell 7 suspended hood 4 is housed, suspended hood exports corresponding with smelting furnace 1; Be provided with slide plate 2 in the fan housing 4, slide plate 2 is connected with the bottom of drying tunnel outlet; The bottom of described housing 7 is provided with the ash discharge cinder notch, and the ash discharge cinder notch is provided with out lime-ash door 13.
After using the utility model, flue gas in the housing 7 is drawn by the two-stage dust removal device from fume emission mouth 10, make high-temperature flue gas in housing 7, rotate, be detained, drying tunnel 6 is among the encirclement of high-temperature flue gas, and to the preheating of heating of materials in the drying tunnel 6, dwindle the temperature difference of material and smelting furnace, can shorten the fusing time of material in smelting furnace, and then can reduce the addition of fuel and reduce the melting cost and raising smelting furnace output capacity.Owing to after adopting the utility model, produce high benefit repayment in the smelting furnace fusion process, therefore positive effect played in the normal operation of environmental protection equipment.
