Abstract
The invention relates to a horizontal-type high temperature hot-blast furnace which comprises a furnace body, a pebble bed, a cold air opening and a hot air opening. The horizontal-type high temperature hot-blast furnace is characterized in that combustion chambers are respectively arranged at the left side and the right side in the furnace body, a plurality of burners are assembled at the bottom of the furnace body and positioned below the combustion chambers, the cold air opening is arranged at the left side of the furnace body, the hot air opening is arranged at the right side of the furnace body, the cold air opening and the hot air opening are respectively communicated with the combustion chambers at the left side and the right side of the furnace body, the pebble bed is arranged at the middle part of the furnace body, checker brick structures are adopted at both sides of the pebble bed, a high-aluminum ball is additionally arranged in the middle of the pebble bed, the diameter of the ball is 10-60 mm and a manhole is arranged at the top of the furnace body. The invention can reduce the fuel consumption and improve the utilization ratio of the energy; and the invention can provide higher preheating temperature, and the furnace body is reduced when the heat-exchange area is the same, therefore, the fabrication cost of the hot blast furnace is reduced. The invention is simple in structure, less in investment and high in heat-exchange efficiency and can easily reach the high heat-exchange temperature with gas with lower calorific value and the heat-exchange efficiency can be up to 80 percent.
Description
Technical field
The present invention relates to a kind of horizontal-type high temperature hot-blast furnace, is a kind of with gases such as coal gas, steam, air, through the high frequency heat exchange, realizes the heat-exchanger rig of superelevation wind-warm syndrome.
Technical background
Traditional hot-blast stove, with supporting copy type hot-blast stove of modern blast furnace and pebble stove is the gas converting heat device of representative, the above-mentioned heat-exchanger rig thermal efficiency is on the low side, hot blast temperature is on the low side, the highlyest can only reach 1250 ℃, bulky, the one-time investment height, particularly use than low combustion value furnace gas combustion heat wind furnace, be difficult to obtain deficiencies such as high wind-warm syndrome.
Summary of the invention
The present invention is for further energy-conservation, reduces carbon dioxide isothermal chamber gas purging, is in particular to adapt to a kind of horizontal-type high temperature hot-blast furnace that blast furnace technology, gas generator technology design gas high efficient heat exchanging needs such as steam, coal gas, air.
The solution that adopts is:
Horizontal-type high temperature hot-blast furnace, comprise body of heater, the ball bed, the cold wind mouth, hot-air mouth, it is characterized in that the left and right sides in the body of heater is respectively equipped with the combustion chamber, the below that the bottom of body of heater is positioned at the combustion chamber is equiped with a plurality of combustion mouths, described cold wind mouth is arranged on the left side of body of heater, described hot-air mouth is arranged on the right side of body of heater, and cold wind mouth and hot-air mouth link with the combustion chamber of the body of heater left and right sides respectively, described ball bed is arranged on the middle part of body of heater, the checker brick structure is adopted in the both sides of ball bed, the middle high alumina bead that adds, the diameter of ball is Φ 10-Φ 60mm, the top of body of heater offers manhole.
Horizontal-type high temperature hot-blast furnace operation principle of the present invention is:
Logical as coal gas and air in burner, the ball bed tempertaure is raise, treat that the ball bed tempertaure is increased to uniform temperature, stop heating then, to introduce from the cold wind mouth and treat recuperated gas, cryogenic gas absorbs ball bed heat through the ball bed, discharges hot-blast stove from hot-air mouth then.When the ball bed tempertaure is equal to or less than the heat exchange temperature, stop cold wind and be blown into, continue to begin heating.
The present invention has following advantage:
1, adopts the heat-accumulating burner heating, make the soot emissions temperature be lower than 150 ℃, reduced fuel consumption, improved energy utilization rate.
2, hot-blast stove of the present invention not only can preheated air, also can preheating gas or water vapour, also can be used for preheating simultaneously and other fuel gas of reforming.
3, hot-blast stove of the present invention can provide higher preheat temperature, and temperature can reach 1250-1450 ℃.
4, hot-blast stove of the present invention, because of having adopted the bead littler than traditional hot wind furnace diameter (φ 10-φ 20mm), when heat exchange area was identical, volume and weight was reduced into original 60-66%, body of heater is also reduced simultaneously, so this hot-blast stove cost is minimized.
5, the present invention is simple in structure, small investment, and the heat exchange efficiency height reaches high heat exchange temperature with low-heat value gas easily, and its heat exchange efficiency can reach 80%.
