Abstract
The utility model discloses a spray powder furnace with a combined type used for raw meal, which consists of a drying device and burning equipment, wherein, the burning equipment comprises an air heating furnace and a coal grinding and dusting machine; a coal air tube of the coal grinding and dusting machine is communicated with a coal powder channel of the air heating furnace; the drying device is communicated with the air heating furnace; the burning equipment still comprises a flame projector which is arranged on the coal powder channel of the air heating furnace. The utility model not only saves space, but also has short ignition time and convenient operation.
Description
Technical field
The utility model relates to a kind of equipment that utilizes coal dust to act as a fuel material is dried, the particularly a kind of raw material oven dry combined type stove that dusts.
Background technology
At present the combined type stove that dusts is one of raw material drying plant common in the cement production process.It is made up of drying unit and burner.Burner is made of hot-blast stove, ignition furnace and coal-grinding and powder-spraying machine, and ignition furnace is arranged between hot-blast stove and the coal-grinding and powder-spraying machine.The operation principle of combined type coal-powder boiler is, at first by the ignition furnace heating, when being heated to uniform temperature, coal-grinding and powder-spraying machine burns coal dust spirt hot-blast stove, the normal back of burning ignition furnace extinguishes, and the heat that the hot-blast stove internal combustion produces enters drying unit inside dries material.Because ignition furnace is made up of inwall, flame shield, siege and body of heater, so its occupation space is big.Simultaneously because ignition furnace when igniting, at first will be cleared up the burning platform, light firewood, firewood fires when prosperous by the time, opens little coal powder injection pipe and burns, reach uniform temperature after, open the coal powder injection pipe again and carry out normal combustion.So the duration of ignition of ignition furnace is long, and this has influenced the operating efficiency of the stove that dusts greatly, and operation is also inconvenient.
The utility model content
The technical problems to be solved in the utility model provides a kind of raw material oven dry combined type stove that dusts, and it not only saves the space, and the duration of ignition is short, easy to operate.
For solving the problems of the technologies described above, the utility model raw material oven dry combined type stove that dusts, it is made up of drying unit and burner, burner contains hot-blast stove and coal-grinding and powder-spraying machine, the coal airduct of coal-grinding and powder-spraying machine and the coal dust passage of hot-blast stove be communications and liaison mutually, drying unit and hot-blast stove be communications and liaison mutually, and burner also contains flame thrower, and this flame thrower is arranged on the coal dust passage of hot-blast stove.
Because adopt the little flame thrower of volume to be arranged on the coal dust passage of hot-blast stove, compared with prior art this has saved the space greatly; Can reach very high temperature in a short period of time owing to flame thrower simultaneously, so coal-grinding and powder-spraying machine can make the hot-blast stove normal combustion by normal in a short period of time Coal powder spray.Compare with existing in addition, flame thrower is simple, convenient.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Accompanying drawing is a structural representation of the present utility model.
1. coal-grinding and powder-spraying machines among the figure, 2. coal airduct, 3. coal dust passage, 4. flame thrower, 5. hot-blast stove, 6. rotary drying machine, 7. tower drier.
The specific embodiment
In the accompanying drawing, burner is made of hot-blast stove 5, flame thrower 4 and coal-grinding and powder-spraying machine 1.The coal airduct 2 of coal-grinding and powder-spraying machine 1 and the coal dust passage 3 of hot-blast stove 5 be communications and liaison mutually.Flame thrower 4 is arranged on the coal dust passage 3 of hot-blast stove 5.Drying unit is made of tower drier 7 and rotary drying machine 6.Formula dryer 7 is positioned at the top of hot-blast stove 5, and rotary drying machine 6 is positioned at the side of hot-blast stove 5.During work, at first open flame thrower 4, when temperature reached certain value, coal-grinding and powder-spraying machine 1 burnt by coal airduct 2 coal dust in coal dust passage 3 enters hot-blast stove 5, and the normal back of burning flame thrower 4 quits work.A large amount of heats that hot-blast stove 5 internal combustion produce enter in the tower drier 7 of drying unit and the rotary drying machine 6 and carry out raw material oven dry operation.Because flame thrower 4 volumes are little, and are arranged on the coal dust passage 3 of hot-blast stove 5, therefore compare with existing ignition furnace, saved the space greatly; Simultaneously because flame thrower is 4 simple to operate, programming rate is fast, this has not only made things convenient for the operator, and has shortened the duration of ignition greatly, has improved the operating efficiency of the stove that dusts.
Claims (1)
1. the raw material oven dry combined type stove that dusts, it is made up of drying unit and burner, burner contains hot-blast stove and coal-grinding and powder-spraying machine, the coal airduct of coal-grinding and powder-spraying machine and the coal dust passage of hot-blast stove be communications and liaison mutually, drying unit and hot-blast stove be communications and liaison mutually, it is characterized in that: burner also contains flame thrower, and this flame thrower is arranged on the coal dust passage of hot-blast stove.
