Description
Technical field
The utility model relates to field of boilers, particularly relates to a kind of hot-blast stove with automatic cleaning function.
Background technology
Hot-blast stove starts extensive use in late 1970s in China as the hot-blast stove of thermal power machinery, and it has become the regeneration product of electric heat source and conventional vapor power heat source in many industries.
By long production practices, it has been recognized that to only have and utilize hot blast could improve heat utilization efficiency and hot working effect larger as medium and carrier.Traditional electrical thermal source and steam thermal power often configure multiple stage circulating fan in course of conveying, make it final or indirect formation hot blast and carry out operation of drying or heat.Obviously there is shortcomings such as wasting energy and cause auxiliary device is too much, complex technical process in a large number in this process.
The effect of blast furnace hot-blast stove is blast heating to the temperature required, in order to improve the returns and efficiency of blast furnace; It is by the work of " accumulation of heat " principle.Burn coal gas in combustion chamber, and high-temp waste gas is by checker brick and make it accumulation of heat, and after checker brick fully heat, hot-blast stove just can change air-supply into, and now each valve of respecting combustion cuts out, and each valve of blowing is opened, and cold wind is heated through checker brick and sends.Blast furnace be equipped with 3-4 seat hot-blast stove/' single stove air-supply " time, two or three heating, an air-supply; Change in turn/' air-supply in parallel " time, two heating.
Chain-arranged type energy-saving hot blast furnace is the hot-blast stove of novel high-efficiency and energy-saving, and product obtains 5 national patents.Be provided with energy-conservation front and back arch in stove, stove rear portion is provided with whirlwind burning chamber, and can ensure the Thorough combustion of fuel, heat loss is low.Its principle is that coal is sent in burner hearth by fire grate, blower fan is blown, and by coal seam, contacts Thorough combustion and produce high-temperature flue gas with the coal on chain, thermal-flame enters secondary combustion chamber and whirlwind secondary furnace burns again, makes hot-blast stove fume blackness lower than " Ringelman 1 ".Chain-arranged type energy-saving hot blast furnace is for thermally-stabilised, and automaticity is high, high-efficiency environment friendly, safe and reliable.
Existing hot-blast stove heat pipe arrangement form is arranged in parallel, S shape is arranged, but its heat pipe is mostly above burner hearth, and heat pipe is densely distributed, space is relatively little, cold wind flows through that the flow process of heat pipe is short, the time is few, heat exchange is insufficient, and heat pipe distance exhaust outlet is comparatively near, and heat energy loss is large.Hot air duct arrangement form mates with heat pipe arrangement form is oriented, and reverse from flue duct heat pipe outlet near enter, by the flue duct heat pipe outer wall of centralized arrangement, then outside flue duct heat pipe import or burner hearth near air-out, complete heat exchanging process.Also have at present in the middle of the reverse air intake of binary channels or air channel and have staggered dividing plate, hot air duct is lengthened relatively, but in general, hot air duct is substantially all transverse crossing flue duct heat pipe, and hot air flow flow process when heat pipe is short, and hot blast is few by the flue duct heat pipe outer wall time, heat exchange is insufficient, flue duct heat pipe energy runs off large, and flue outlet wind is without again utilizing mechanism, so ubiquity power consumption is high, the thermal efficiency is low, waste energy serious problem.
To sum up, there is the problem that power consumption is high, the thermal efficiency is low in existing hot-blast stove, wastes energy serious, have impact on hot-blast stove and further develop; Meanwhile, hot-blast stove of the prior art is not all provided with cleaning device and cleans after burning terminates.。
