Description
Technical field
The utility model relates to a kind of pluralities of fuel of selecting for use, and the combustion apparatus of a plurality of burner hearths is arranged, especially a kind of no flue dust second-time burning environmental protection and energy saving hot-blast stove.
Background technology
At present, the hot-blast stove that uses in the society mainly is a coal-fired hot-blast stove, secondly is combustion bavin hot-blast stove and a spot of fuel oil (combustion gas) hot-blast stove.Its fuel all is to carry out disposable burning.Coal-fired, combustion bavin Combustion of Hot Air Furnace is incomplete, so fuel consumption is many, the thermal efficiency is low, the flue gas dust concentration height of discharge, blackness of exhaustion is big, and environmental protection is caused severe contamination.Fuel oil (combustion gas) hot-blast stove, though fuel is fully burned, fume emission also reaches environmental protection requirement, but fuel oil (combustion gas) hot-blast stove is with respect to cost height coal-fired, combustion bavin hot-blast stove, its running cost is 4 to 6 times of coal-fired hot-blast stove, therefore China at present produce and fuel oil (combustion gas) hot-blast stove of use in life very few, and fire coal big for environment pollution, the use amount of firing the bavin hot-blast stove account for more than 70%.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, cheap, sufficient combustion, thermal efficiency height, and operating cost is low, the smokeless second-time burning environmental protection and energy saving hot-blast stove that environmental pollution is few.
Architectural feature of the present utility model is: semi-enclosed main burning furnace thorax is set in internal furnace, and promptly the bottom in the internal furnace is provided with the main burning furnace thorax, and the middle part is provided with the secondary air register, and top is provided with time burner hearth.Be arranged on the some lower smoke tubes one termination dirt pocket between internal furnace and the middle shell, another termination time burner hearth.Be arranged on the some upper smoke tubes one termination dirt pocket between internal furnace and the middle shell, another termination collection smoke box.
The characteristics of this hot-blast stove: fuel adopts semiclosed second-time burning, simple, the easy manufacturing of furnace type structure, saving material, and cheap, set-up time weak point, safe and reliable, fuel consumption is few, and service life is long.This furnace thermal efficiency is up to 90%, and smoke dust discharge concentration is less than 100mg/m
3, the fume emission lingemann blackness is less than 1 grade, and soot emissions reach fuel oil (combustion gas) hot-blast stove standard, are better than national two class regional standards.This hot-blast stove can fire coal, firewood, wooden chaff, house refuse etc., is the regeneration product of present fire coal, combustion bavin hot-blast stove, has vast market demand and good economic benefit.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The utility model mainly is made up of furnace shell 1, internal furnace 2, main burning furnace thorax 3, secondary air register 4, inferior burner hearth 5, lower smoke tube 6, upper smoke tube 7, hot-blast outlet 8, collection smoke box 9, exhaust opening 10, cold wind import 11, middle shell 12, fire door 13, refractory material 14, dirt pocket 15, furnace base 16, fan interface 17 etc.Internal furnace 2 is welded on the furnace base 16, main burning furnace thorax 3 is arranged on the bottom in the internal furnace 2 and uses refractory material 14 heat insulation, middle part, main burning furnace thorax 3 that secondary air register 4 is placed in the flue 2 push up, inferior burner hearth 5 is installed on internal furnace 2 internal upper parts, secondary air register 4 tops, bottom, furnace base 16 that dirt pocket 15 is welded on internal furnace 2 outsides push up, collection smoke box 9 is welded on internal furnace 2 tops, and exhaust opening 10 is welded on collection smoke box 9 tops.Equally distributed some lower smoke tubes 6 are arranged between internal furnace 2 and the middle shell 12, a termination dirt pocket 15, another termination time burner hearth 5 tops; Equally distributed some upper smoke tubes 7 are arranged between internal furnace 2 and the middle shell 12, a termination dirt pocket 15, another termination collection smoke box 9.Furnace shell 1 is welded on the furnace base 16, and cold wind import 11 is welded on furnace shell 1 top.Hot-blast outlet 8 one ends are welded in middle shell 12 tops, and the other end is welded in furnace shell 1 top.Fire door 13 1 ends are welded on the furnace shell 1, and the other end is welded on the internal furnace 2.Fan interface 17 is welded on the furnace base 16, and middle shell 12 is welded on the collection smoke box 9.
The course of work of the present utility model: fuel carries out semi-close burning mode in the main burning furnace thorax, regulates the size control burning velocity of blower fan air intake, heat energy flow air in internal furnace is passed to hot-blast stove that burning produces.The flue gas that burning produces enters time burner hearth behind secondary air register air distribution, combustibles such as the carbon particulate that burns incompletely in the flue gas, free carbon, carbon monoxide and fuel gas obtain burning cmpletely once more in inferior burner hearth, the heat energy that burning produces is passed to flow air in the hot-blast stove by internal furnace, lower smoke tube and upper smoke tube, the air heat absorption is after hot-blast outlet uses for the user, and the flue gas that burning produces enters through lower smoke tube and discharges out of the furnace through exhaust opening from upper smoke tube after dirt pocket purifies.
