Abstract
The utility model discloses a cast iron pipe combined hot blast furnace, which is composed by a gas combustion furnace, a cast iron pipe heat exchanger and a steel pipe heat exchanger, a vertical combustion chamber (5) surrounded by a furnace grate (2), a furnace wall and a furnace arc is provided within the gas combustion furnace, the cast iron pipe heat exchanger (6) is directly connected with a gas outlet of the vertical combustion chamber (5), the cast iron pipe heat exchanger (6) is directly connected with the steel pipe heat exchanger. The gas directly enters into the heat exchanger from the combustion furnace and heats cold air in the heat exchanger to feed into laneway. The utility model has sufficient fuel combustion, high heat efficiency, small occupied area and long service life.
Description
Technical field
The utility model relates to a kind of hot air generator, relates in particular to a kind of supporting hot-blast stove of mine laneway heating that is.
Background technology
At present, combustion furnace and heat exchanger in the hot-blast stove that the heating and ventilation of northern China mine is used are on the ground horizontally disposed, cause occupation area of equipment big, and the efficiency of combustion of combustion furnace is low, and heat loss is big; The heat exchanger non-refractory, service life of equipment is short.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of existing hot-blast stove, provides a kind of energy-efficient, and floor space is little, the hot-blast stove that the life-span is long.
The utility model is realized in the following way:
A kind of cast iron tubular type is hot-air furnace combined, adopts a smoke combustion stove and two heat exchanger combinations, and the smoke combustion chamber surrounds horizontal firing chamber and vertical combustion chamber by furnace wall, fire grate, chimney arch.The cast iron pipe heat exchanger directly is connected with the outlet of vertical combustion chamber, the cast iron pipe heat exchanger directly is connected with the steel pipe heat exchanger by flue gas collection case, arrive the cast iron pipe heat exchanger after hot flue gas comes out from combustion furnace vertical combustion chamber and enter the steel pipe heat exchanger through flue gas collection case, high-temperature flue gas is sent into the tunnel with the heating of the cold air in heat exchanger back by pipeline.
The utility model has following effect:
1. utility model cast iron tubular type is hot-air furnace combined, and combustion furnace and two kinds of heat exchangers are organically gathered together, and it is little to have floor space, and the investment of equipment capital construction and factory building is reduced.
2. the combustion chamber has adopted horizontal firing chamber and vertical combustion chamber to form, and fuel combustion is more abundant, and heat utilization efficiency improves, fuel saving.
3. the cast iron pipe heat exchanger has adopted resistant to elevated temperatures cast iron pipe, improves the service life of equipment.
Description of drawings
Fig. 1 is the hot-air furnace combined structural representation of cast iron tubular type that the utility model proposes:
Specific embodiments
Please refer to shown in Figure 1ly, the utility model cast iron tubular type is hot-air furnace combined, comprises by coaling machine (1) and coaling machine (1) back forming combustion furnace by horizontal firing chamber (4) and vertical combustion chamber (5) that fire grate (2) and furnace wall (3) chimney arch constitute; Back in coaling machine (1), horizontal firing chamber (4) just above build into vertical combustion chamber (5) by laying bricks or stones, the outlet of vertical combustion chamber (5) connects cast iron pipe heat exchanger (6), cast iron pipe heat exchanger (6) links to each other with steel pipe heat exchanger (7) by flue gas collection case (12).Cast iron pipe heat exchanger (6) and steel pipe heat exchanger (7) be arranged in horizontal firing chamber (4) directly over.
The coal-fired fire grate of being sent in the horizontal firing chamber (4) by coaling machine (1) (2) is gone up burning, the formed flue gas that burns will enter fully burning once more in the vertical combustion chamber (5) through the thermal-flame district, the cast iron pipe (8) that enters then in the cast iron pipe heat exchanger (6) flows in the flue gas collection case (12), again by discharging in the steel pipe (9) of steel pipe heat exchanger (7) lining; Air enters heating outside steel pipe (9) in the steel pipe heat exchanger (7) by air intlet (10), enters then in the cast iron pipe heat exchanger (6) and enter the tunnel by air outlet slit (11) discharge after cast iron pipe (8) heats once more.
Claims (2)
1. the cast iron tubular type is hot-air furnace combined, is made up of smoke combustion stove and heat exchanger, it is characterized in that: have horizontal firing chamber (3) and vertical combustion chamber (4) to form at the smoke combustion stove; Fuel fully burns flowing to the vertical combustion chamber after the horizontal firing Indoor Combustion earlier.
2. cast iron tubular type as claimed in claim 1 is hot-air furnace combined, and what it is characterized in that heat exchanger tube in the cast iron pipe heat exchanger (6) adopts is resistant to elevated temperatures cast iron pipe (8).
