Description
Technical field
This utility model is related to a kind of incinerator, espespecially a kind of fluidized bed incinerator.
Background technology
With industrialized development and the rise of environmentally friendly concept, the garbage of water-containing sludge class is burnt with incinerator mostly
Burning mode is processed, and with decrement and reduces pollution.A kind of existing fluidized bed incinerator to burning waste is by burner
The siege top of body of heater is arranged at, burner adds downwards hott bed sand when furnace lifting is burnt, then takes out normal temperature air by aerator
Enter air compartment, normal temperature air is entered in bed sand again by air distribution plate, when the flow velocity of high temperature air exceedes the bed sand of burned device heating
Minimum fluidisation speed when, the bed sand of burned device heating bubble of accompanying in burner hearth seethes to form fluidized bed up and down.Stream
The bed sand of body is big with garbage contact area, and heat transfer effects are good, and temperature distribution is average, high combustion efficiency.
However, burner to be arranged at above-mentioned incinerator the design above the siege of body of heater, burn when being burnt due to furnace lifting
Device adds downwards hott bed sand, and high temperature air can loss upwards so that bed sand temperature rises relatively slow, therefore the furnace lifting time is longer,
Energy resource consumption is higher.
Existing another kind is that burner is arranged in air compartment to the fluidized bed incinerator of burning waste, in furnace lifting
Normal temperature air suction air compartment is heated to be high temperature air by aerator during burning outside air compartment by burner, and high temperature air leads to again
Cross air distribution plate to enter in bed sand, when the flow velocity of high temperature air exceedes the minimum fluidisation speed of bed sand, bed sand companion in burner hearth
Seethe to form fluidized bed up and down with bubble.
However, above-mentioned incinerator is arranged at burner in air compartment and in air compartment to the design of normal temperature air heating, make
Air compartment shape same chamber is obtained, therefore the air compartment of above-mentioned fluidized bed incinerator and the high temperature resistant demand of burner housing are higher,
The cost for building fluidized bed incinerator is caused to increase.Additionally, the normal temperature air of aerator suction air compartment some meeting elder generation Jing
Air distribution plate is crossed into bed sand, the normal temperature air of another part just can be heated by burner combustion, therefore above-mentioned incinerator will fire
Burner is arranged at the operation of the fluidized bed incinerator of air compartment slightly can not cause at once the efficiency of heating surface not good so that the furnace lifting time
It is longer, and energy resource consumption is higher.
Therefore, how to solve above-mentioned problem of the prior art and shortcoming, as the inventor of this case be engaged in the industry
Relevant manufactures desire most ardently research improve direction be located.
Utility model content
