Abstract
The utility model relates to a cupola of straight-combustion type top-mounted combustion chamber, which comprises a cupola body at lower part, and a top-mounted combustion chamber shell arranged above the cupola body; the top-mounted combustion chamber shell is provided with a feeding opening at lower part and internally provided with a fire-resistant material. The cupola of straight-combustion type top-mounted combustion chamber has the advantages of simple structure, low price, less element burning loss in molten iron, high tapping temperature and good quality for molten iron, low labor intensity, low burden cost, smoke elimination and dust removal, and long service life. The utility model can be widely applied in the smelting process of molten iron in casting industry.
Description
Affiliated technical field the present invention relates to a kind of direct-fired overhead combustion chamber furnace cupola, can be widely used in the fusion process of casting industry molten iron.
The existing furnace cupola of background technology, combustion chamber normally are arranged on a side of furnace cupola, and melting loss of elements is many in the molten iron, and the molten iron temperature of coming out of the stove is low, of poor quality; The CO discharge capacity is big in the flue gas, furnace charge expense height, and labour intensity is big, and heat exchange efficiency is low, and heat exchanger is short service life.
Summary of the invention the object of the present invention is to provide a kind of simple in structure, cost is low, few, the molten iron temperature height and quality is good, labour intensity is little, the furnace charge expense is low, the direct-fired overhead combustion chamber furnace cupola of smoke abatement and dust control, long service life of coming out of the stove of melting loss of elements in the molten iron.
In order to achieve the above object, the direct-fired overhead of the present invention combustion chamber furnace cupola comprises the cupola body that is positioned at the bottom, is installed in the overhead burning chamber shell of body of heater top; Said overhead burning chamber shell, the bottom is provided with charge door, and inside is provided with refractory material.
The direct-fired overhead of the present invention combustion chamber furnace cupola, its operation principle is: in the high-temperature flue gas that rises from the furnace cupola combustion chamber, the potential chemical heat and the physics heat that have the CO more than 13%, CO meets the air completing combustion voluntarily that charge door and blast pipe enter in the combustion chamber, flue gas is heated to 800 ℃～900 ℃, high-temperature flue gas enters heat exchanger, heat exchanger by exchange heat air heat to 400 ℃～600 ℃ after warm-air pipe is sent into the furnace cupola air port.
The direct-fired overhead of the present invention combustion chamber furnace cupola, simple in structure, cost is low, utilize the physics heat and the chemical heat preheating air-supply of furnace gas, the heat that makes full use of coke improves furnace temperature, forms the excellent metallurgical environment, melting loss of elements is few in the molten iron, and the molten iron temperature height of coming out of the stove, quality are good.The wind supply quantity of combustion chamber can be adjusted automatically according to hot blast temperature, keeps hot blast temperature to be stabilized in the technique initialization value, helps stable furnace condition, workman's processing ease, and labour intensity is little.
The direct-fired overhead of the present invention combustion chamber furnace cupola, direct-fired overhead combustion chamber is arranged on cupola charging mouth top, and overhead burning chamber shell tubular construction inner lining refractory has the effect that is incubated and prevents the outer tube wall scaling loss, the furnace cupola long service life.
The direct-fired overhead of the present invention combustion chamber furnace cupola, the combustion chamber directly is connected with heat exchanger, can make full use of the heat of flue gas, realizes the CO spontaneous combustion, and the abundant burning of CO makes that the CO discharge capacity reduces to trace in the flue gas, reaches the purpose of smoke abatement and dust control.
The direct-fired overhead of the present invention combustion chamber furnace cupola, high temperature and excellent metallurgical condition have been relaxed the requirement to furnace charge, can use the frivolous furnace charge of low-quality, thereby reduce the furnace charge expense.
In sum, the direct-fired overhead of the present invention combustion chamber furnace cupola, simple in structure, cost is low, and melting loss of elements is few in the molten iron, and the molten iron temperature of coming out of the stove is high and quality is good, and labour intensity is little, and the furnace charge expense is low, smoke abatement and dust control, long service life.
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 the direct-fired overhead of the present invention combustion chamber furnace cupola comprises the cupola body 1 that is positioned at the bottom, is installed in the overhead burning chamber shell 2 of body of heater top; Said overhead burning chamber shell, the bottom is provided with charge door 3, and inside is provided with refractory material 4.
In addition, in Fig. 1, overhead burning chamber shell top exhanst gas outlet a connects heat exchanger.
