Technical field
The utility model relates to a kind of air heating plant, is specifically related to a kind of hot-blast stove.
Background technology
In industrial processes, utilize hot blast as medium and carrier can be larger improve heat utilization efficiency and hot working effect.Traditional electrical thermal source and steam thermal power often configure many circulating fans in course of conveying, final or indirectly form the hot blast operation of drying or heat.The obvious existence of this process wastes energy in a large number and causes the shortcomings such as auxiliary device is too much, complex technical process.And larger problem is, this thermal source, for that requirement that needs higher temperature to be dried or to toast operation, can not reach higher technological requirement.
Existing hot-blast stove mostly adopts burner hearth directly warm-air pipe to be heated, and has reduced unnecessary equipment, has improved the conversion efficiency of energy.But existing hot-blast stove also has problems in the design of burner hearth and warm-air pipe, can not efficiently utilize for the heat of fuel combustion in burner hearth, caused the waste of fuel, increase the use amount of fuel, made hot-blast stove discharge a large amount of greenhouse gases, caused the larger pollution to environment.
So, in order to overcome the defect of existing hot-blast stove, need to design a kind of heat that can efficiently utilize burner hearth fuel combustion, reduce fuel use amount, reduce greenhouse gas emissions, reduce the hot-blast stove of environmental pollution.
Utility model content
The utility model technical issues that need to address are just to overcome the defect of prior art, and a kind of hot-blast stove is provided, and it can efficiently utilize the heat of burner hearth fuel combustion, reduce fuel use amount, reduce greenhouse gas emissions, reduce environmental pollution, meet industrial technological requirement.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of hot-blast stove, hot-blast stove is provided with cube shaped body of heater, is provided with the heating chamber that is positioned at upper of furnace body and the burner hearth that is positioned at lower portion of furnace body in body of heater; In order to improve the utilization rate of heat, in heating chamber, be provided with the heating air duct of M shape, one end of heating air duct is provided with the air inlet that stretches out body of heater, and the other end of heating air duct is provided with the air outlet that stretches out body of heater, and air inlet is provided with blower fan; Burner hearth is provided with fuel inlet for adding fuel and for observing the peep hole of hearth combustion situation; The leakage hawk downside of burner hearth lower end is provided with burner hearth air intake duct, and in order to improve the efficiency of combustion of fuel, burner hearth air intake duct is provided with air blast.
The utility model, in order to improve the fuel economy of burner hearth, reduces the use amount of fuel, and preferably technical scheme is, the upper end of body of heater is provided with the exhaust opening for discharging combustion product gases.
The utility model, in order to improve the absorption conversion efficiency of heat, reduces fuel use amount and environmental pollution, and preferably technical scheme also has, and the aluminium alloy plate that the tube wall of heating air duct is 2mm by thickness is prepared from.
The utility model, in order to reduce heat loss, improves the transformation efficiency of heat, and preferably technical scheme also has, and the outer wall of body of heater is provided with thermal insulation separation thermosphere.
The utility model is in order to improve the working life of hot-blast stove, and preferably technical scheme also has, and the inwall of burner hearth is provided with the refractory brick for preventing that burner hearth from burning out.
Advantage of the present utility model and beneficial effect are: the utility model hot-blast stove is provided with the heating air duct of M shape, can efficient absorption and the heat that produces of conversion hearth combustion, thus improved the utilization rate of heat, reduced fuel use amount and greenhouse gas emissions; The utility model hot-blast stove adopts aluminium alloy plate to prepare heating air duct, and having improved heat is absorptivity; The utility model hot-blast stove is provided with thermal insulation separation thermosphere and refractory brick, has improved the working life of hot-blast stove, has improved the energy-conserving and environment-protective performance of hot-blast stove.
