Abstract
The utility model relates to a cyclone separator of a recirculating fluidized bed boiler, belonging to a component of a thermotechnical facility, wherein a central barrel is arranged in a shell. The cyclone separator is characterized in that the central barrel deviates to one side of the shell; the space between the central barrel and the shell is big at an air inlet and small at a leeside port; and a fire-resistant insulating layer is attached outside the shell. The cyclone separator has simple structure, can reduce the heat loss and has good coal-saving effect; therefore, the output of the fluidized bed boiler can be improved.
Description
Technical field
The utility model relates to a kind of cyclone separator of circulating fluidized bed boiler, belongs to thermal technology's facility parts.
Background technology
Owing in whole burner hearth, form the higher air-flow body of one concentration during burning in circulating fluid bed boiler, and fast turn-around in burner hearth, and running the time concentrates on the burner hearth middle part, dilute-phase zone when special, the water-cooling wall of upper furnace will reduce the absorption of heat like this, and a large amount of heats can not get absorbing and just enters cyclone separator, and the unburnt medium of part enters afterbody by central tube, not only thermal loss is excessive simultaneously, also superheater on the recirculating fluidized bed and economizer is caused wearing and tearing.
The utility model content
The purpose of this utility model is to provide a kind of improved cyclone separator of circulating fluidized bed boiler, and thermal loss is few, and effect of coal saving is good, fluidized-bed combustion boiler is improved exert oneself.
Enter the combustion chamber based on the collected medium of cyclone separator by revert system and participate in circulating combustion, the utility model is transformed cyclone separator of circulating fluidized bed boiler, be provided with central tube in the cyclone separator shell, it is characterized in that between central tube and shell for equidistantly not being provided with, one side of central tube deflection shell, spacing between central tube and shell is big at the air inlet place, and is little at leeward mouthful of place, the half as much again that central tube and shell are preferably located at leeward mouth at the radial spacing at air inlet place.
So, cyclone separator can be collected the participation circulating combustion as much as possible to medium, has increased circulating ratio, has improved the recycling rate of waterused of heat, reaches the effect of economizing on coal, and makes boiler reduce coal consumption.Because increasing of circulating ash, the concentration of dilute-phase zone is improved has also increased heat, reaches the effect of economizing on coal thereby also make the water-cooling wall of upper furnace increase uptake, makes medium make full use of, thereby perfect whole combustion system has improved CFBB and exerts oneself.
Refractory insulating layer is set up in the outside at shell, reduces thermal loss, saves coal-fired.
The utility model cyclone separator of circulating fluidized bed boiler, simple in structure, can reduce thermal loss, effect of coal saving is good, fluidized-bed combustion boiler is improved exert oneself.
Description of drawings
Fig. 1, the utility model one embodiment cross-sectional structure schematic diagram.
Among the figure: 1, refractory insulating layer 2, shell 3, central tube L1, L2, radial spacing.
The specific embodiment
The utility model is described in further detail in conjunction with the foregoing description accompanying drawing.
As shown in the figure, cyclone separator of circulating fluidized bed boiler described in the utility model, be provided with central tube 3 in the shell 2, one side of central tube 3 deflection shells 2, be that 2 on central tube 3 and shell are setting equidistantly, the spacing that central tube 3 and shell are 2 is big at the air inlet place, little at leeward mouthful of place, central tube 3 in the diagram and the radial spacing L1 of shell 2 at the air inlet place are the half as much agains at the radial spacing L2 at leeward mouthful of place, as one is 1050mm, one is 700mm, and the outside of shell 2 is with refractory insulating layer 1.
Two cyclone separators are side by side arranged in the diagram.
Claims (3)
1. a cyclone separator of circulating fluidized bed boiler is provided with central tube in the shell, it is characterized in that a side of central tube deflection shell, and the spacing between central tube and shell is big at the air inlet place, and is little at leeward mouthful of place.
2. cyclone separator of circulating fluidized bed boiler according to claim 1 is characterized in that central tube and the shell radial spacing at the air inlet place is the half as much again at leeward mouthful of place.
