With higher heat exchange efficiency.
Wherein, the bottom of the second Heat Room 902 is provided with the second heavy grey room 11, the described second heavy grey room 11 and dirt pocket 12
Bottom connects, and the dirt pocket 12 is provided with least one layer of basket strainer.
In the present embodiment, continue heavy ash purification from the tail gas that the second Heat Room 902 comes out in the second heavy grey room 11, have
Beneficial to the solid waste content in the tail gas for reducing discharge, environmental protection.Second heavy grey room 11 is provided with the second clean-up port 19,
It is easy to the cleaning of laying dust in the second heavy grey room 11.
The tail gas come out from the second heavy grey room 11 enters dirt pocket 12, and removing dust net carries out dust removal and filtration, dirt pocket 12
Top is provided with exhaust outlet, and air-introduced machine 20 can be set in exhaust ports, makes the tail gas removing dust room after heat exchange smoothly from the heat
Discharged inside wind furnace.Dirt pocket is further removed to the solid waste in tail gas, can be removed completely in tail gas substantially
Solid impurity, prevent burning after caused dust be directly discharged in environment, be advantageous to environmental protection, solve existing hot blast
The problem of dust existing for the tail gas that fire grate goes out is more, and smog is big；Meanwhile dirt pocket 12 is close to the air inlet 101 of furnace shell 1, cooling
The cavity that enters from air inlet 101 between furnace shell 1 and dirt pocket 12 of wind, because the tail gas in dirt pocket 12 may also have one
Fixed temperature, the cold wind entered from air inlet 101 can be preheated, you can further lower the temperature of the tail gas of discharge,
Heat energy caused by fuel combustion can be made full use of.The hot-blast stove that the present embodiment provides, using multi-stage heat exchanger mode, makes heat energy utilization
More fully, while the dust after burning, smog are by repeatedly sinking to heavy grey room and dirt pocket 12 filters, play good energy-conservation,
Environmental-protection function.
The hot-blast stove that the present embodiment provides, whole work process are specifically as follows：
Fuel is delivered in the first burner hearth 201 by feeder 14 from charging aperture 13, and fuel falls into the bottom of the first burner hearth 201
Burning is carried out on grate 15 and produces heat, the wind that air blower 4 occurs, from the first blast pipe 3, and passes through Whirl deposite tank by bellows 6
Device 5 produces Whirl deposite tank, enters the first burner hearth 201 from the lower section of grate 15 of the bottom of the first burner hearth 201, Whirl deposite tank due to wind direction not
, and interact with the side wall of the first burner hearth 201 in the first burner hearth 201 and constantly change, not only to combustion process
In fuel there is tipping effect, and make the air in the first burner hearth 201 more uniform so that fuel combustion is abundant, production
Raw more heat.
Slag charge, dust after fuel combustion fall into the cinder pocket of the lower section of grate 15, and can be discharged by lower furnace door 16, burning production
Raw hot gas, fuel gas and powder particle fuel is under the drive of Whirl deposite tank to the ionized motion of the first burner hearth 201, air blower 4
The wind of generation enters the top of the first burner hearth 201 by bellows 6 from the second blast pipe 7, and the oxygen of abundance is provided for the top of the first burner hearth 201
Gas, fuel gas and powder particle burning carry out second-time burning on the top of the first burner hearth 201 and continue to produce heat, hot gas, unburned
Burn complete fuel gas and powder particle fuel and enter the second burner hearth 202 from the top of the first burner hearth 201, and air blower 4 is sent out
Raw wind enters the second burner hearth 202 by bellows 6 from the 3rd blast pipe 8, and the oxygen of abundance is provided for the burning in the second burner hearth 202
Gas.
Fuel passes through repeated combustion, and final burning is complete, and produces substantial amounts of heat, carry the hot gas of amount of heat from
The bottom of second burner hearth 202 enters the first heavy grey room 10 and carries out precipitating the preliminary dust larger except degranulation, is changed subsequently into first
Hot cell 901 is exchanged heat, and is exchanged heat again into the second Heat Room 902, and the gas after heat exchange enters the second Heat Room 902
The heavy grey room 11 of the second of bottom carries out second of heavy ash purification, and the tail gas after precipitating dedusting twice is carried out into dirt pocket 12
Dust separation, the tail gas of solid impurity is eliminated substantially, discharged out of the furnace by air-introduced machine 20.
Meanwhile natural cold wind enters from the air inlet 101 of the one end of furnace shell 1, its direction of motion and hot gas caused by burning
Mass motion is in opposite direction, and natural cold wind initially enters the cavity between dirt pocket 12 and furnace shell 1, due to the tail in dirt pocket 12
Gas there is likely to be a small amount of preheating after heat exchange, and its temperature is likely to be greater than nature cold wind, therefore, natural cold wind except
Heat exchange occurs with tail gas at dirt room 12, had both reduced the temperature of tail gas, advantageously reduces the thermal pollution of tail gas, and can be to certainly
Right cold wind is preheated, and the wind after preheating continues to 1 another end motion of furnace shell, and is changed successively in the second Heat Room 902 and first
Hot cell 901 is exchanged heat with hot gas caused by burning, becomes the hot blast with a large amount of heat energy, then by burner hearth 2 and furnace shell 1 it
Between cavity, finally discharged by the air outlet 102 of the other end of furnace shell 1, demand and supply hot blast can equipment.By repeatedly exchanging heat,
Heat exchange efficiency is high.
The foregoing description of the disclosed embodiments, professional and technical personnel in the field are enable to realize or using the present invention.
