Abstract
A carbon bed natural gas cupola comprises a furnace body, an iron tapping mouth, a slag tapping hole, a fire grate located in a combustor and arranged on the furnace body, a carbon bed arranged above the fire grate and a metal material layer arranged above the carbon bed, wherein the iron tapping mouth and the slag tapping hole are installed below the furnace body. The carbon bed natural gas cupola of the utility model only produces few harmful elements and is excellent in smelting property, high in thermal efficiency, fine in casting quality, energysaving, environment-friendly and saving in investment. The carbon bed natural gas cupola can be widely applied to the smelting processes of liquid iron in casting industry.
Description
Affiliated technical field the present invention relates to a kind of charcoal bed natural gas furnace cupola, can be widely used in the fusion process of casting industry molten iron.
The existing furnace cupola of background technology, being generally the burnt furnace cupola of combustion, is fuel with the coke, and molten iron has the phenomenon that increases sulphur, carburetting, melting loss of elements is bigger, it is insufficient to burn, and energy utilization rate is low, and power consumption is high, technological parameter is difficult to control, be difficult to satisfy the technological requirement of foundry goods, harmful elements such as a large amount of S, P enter molten iron, the cost of investment height in the fusion process.And discharge a large amount of flue gases during melting, and containing flammable carbon granule and imflammable gas in the flue gas, smoke discharge amount is big, has both caused environmental pollution, wastes a large amount of heat energy again.
Summary of the invention the object of the present invention is to provide that a kind of harmful element is few, the melting performance is good, the thermal efficiency is high, casting quality is good, the charcoal bed natural gas furnace cupola of energy-conserving and environment-protective, reduced investment.
In order to achieve the above object, charcoal bed natural gas furnace cupola of the present invention comprises body of heater, is installed in the tapping a blast furnace of body of heater below, cinder notch, is arranged in the combustion chamber and is installed in grate on the body of heater, the charcoal bed that is provided with, the metal bed of material that is provided with above grate above the charcoal bed.
Charcoal bed natural gas furnace cupola of the present invention, said charcoal bed is coke layer.
Charcoal bed natural gas furnace cupola of the present invention, said charcoal bed is charcoal piece layer.
Charcoal bed natural gas furnace cupola of the present invention, its operation principle is: being main fuel with the natural gas, serves as the main overheated and metallurgical medium of supporting metal charge with coke or carbon piece, realizes Castiron Melting.Natural gas burns in coke or carbon piece bottom, top and gap, and metal charge melts at coke or above the carbon piece, realizes overheated and metallurgical process in flow through coke or the carbon piece layer process.
Charcoal bed natural gas furnace cupola of the present invention, because adopted is the melting mode of main fuel with the natural gas, sufficient combustion, the energy utilization rate height cuts down the consumption of energy, and the thermal efficiency increases, can make molten iron temperature improve about 20 ℃, melting loss of elements such as C, Si is light, has improved molten iron temperature, has to smelt environment preferably.
Charcoal bed natural gas furnace cupola of the present invention is compared with existing furnace cupola, reduces harmful elements such as S, P and enters molten iron, and the melting performance is good, and the casting quality height is energy-conservation.Smoke discharge amount reduces, and the slag generation reduces, and helps environmental protection.
Charcoal bed natural gas furnace cupola of the present invention, easy and simple to handle, cost is low, and the melting rate height can be worked continuously, and is energy-saving and cost-reducing, and safety and environmental protection meets the energy-saving and emission-reduction policy of national environmental protection, and the purpose that both reached energy-conservation, improves molten steel quality has realized environmental protection requirement again.
Charcoal bed natural gas furnace cupola of the present invention, original furnace cupola can directly be transformed, and the required investment of supporting cleaner is less, can reduce investment outlay.
In sum, charcoal bed natural gas furnace cupola of the present invention, it is few to produce harmful element, and the melting performance is good, thermal efficiency height, casting quality is good, energy-conserving and environment-protective, reduced investment.
Description of drawings is done further explanation below in conjunction with accompanying drawing and embodiment to the present invention.
Fig. 1 is a structural representation of the present invention;
The specific embodiment is in Fig. 1, and charcoal bed natural gas furnace cupola of the present invention comprises body of heater 1, be installed in the tapping a blast furnace of body of heater below, cinder notch 2, be arranged in the combustion chamber and be installed in grate 3 on the body of heater, the charcoal bed 4 that above grate, is provided with, the metal bed of material 5 that above the charcoal bed, is provided with.
Charcoal bed natural gas furnace cupola of the present invention, said charcoal bed is coke layer.
Charcoal bed natural gas furnace cupola of the present invention, said charcoal bed is charcoal piece layer.
