Description
Technical field
The utility model relates to the body of heater that material reaction is used in the chemical field, relates in particular to a kind of improved fluidized bed furnace.
Background technology
Fluidized bed furnace is the roasting apparatus that is widely used in pyrometallurgical smelting, and it comprises body of heater, and body of heater is provided with charge door, discharging opening and exhaust outlet, and is arranged on the blast cap etc. that bottom of furnace body is used for air feed in the stove.The height of traditional fluidized bed furnace and the boiling section of inner chamber thereof is mostly lower, furnace charge is short at the boiling residing time in furnace, thereby the insufficient of furnace charge roasting occurs easily, especially, for example for the nickelic sulphur of roasting (for example, being rich in the mineral aggregate of Ni3S), if the temperature in the increase stove, Ni3S melts easily, and the roasting of sulphur is insufficient, bonds easily.In addition, carry easily the furnace charge grain in the waste gas after the roasting secretly, discharge fluidized bed furnace with waste gas, not only cause the waste of furnace charge, and cause the dustiness in the waste gas to increase contaminated environment.
The utility model content
For deficiency of the prior art, the utility model provide furnace charge grain in a kind of waste gas less, be beneficial to the improved fluidized bed furnace of material thorough roasting.
In order to reach the foregoing invention purpose, the technical solution adopted in the utility model is for providing a kind of improved fluidized bed furnace, and this improved fluidized bed furnace comprises: comprise air-blast device, charging aperture, outlet flue, body of heater, heat-insulation layer and discharging opening; Described heat-insulation layer is arranged on the outside of body of heater; The intake stack of described air-blast device passes the bottom that heat-insulation layer and body of heater are arranged on body of heater; Described discharging opening is arranged on the bottom of body of heater, and charging aperture is arranged on the top of body of heater, and outlet flue is arranged on the top of body of heater; It is characterized in that: also comprise screen cloth and some fuel gas inlet, be provided with igniter on the sidewall of fuel gas inlet; Be provided with filter screen in the described outlet flue; Described screen cloth is arranged on the middle and lower part of body of heater, and fuel gas inlet passes heat-insulation layer and body of heater is arranged on body of heater inside.
Preferably, be provided with at least three fuel gas inlet on the described body of heater.
Preferably, be provided with two-layer filter screen in the described outlet flue, and filter screen from the bottom to top the order number increase gradually.
In sum, the beneficial effects of the utility model are:
1, the fuel gas inlet that arranges in the Different Plane of body of heater of this improved fluidized bed furnace can realize the thorough roasting to the furnace charge on the different aspects of body of heater inside, and the material that effectively guarantees body of heater inside reaches produces needed granularity.
2, the screen cloth of the middle and lower part of body of heater setting can stop effectively that granularity does not reach the material of production requirement, reaches the material of producing required granularity and just can pass through fast, and the material that does not reach the reaction requirement can be blown afloat roasting again by air-blast device.
3, the filter screen that arranges in the outlet flue can filter dust and the material particles carried secretly in the flue gas effectively.
Description of drawings
Fig. 1 is the structural representation of improved fluidized bed furnace.
Wherein, 1, air-blast device; 2, screen cloth; 3, charging aperture; 4, outlet flue; 41, filter screen; 5, body of heater; 6, fuel gas inlet; 61, igniter; 7, heat-insulation layer; 8, discharging opening.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further description:
As shown in Figure 1, this improved fluidized bed furnace comprises: air-blast device 1, charging aperture 3, outlet flue 4, body of heater 5, heat-insulation layer 7 and discharging opening 8; Described heat-insulation layer 7 is arranged on the outside of body of heater 5; The intake stack of described air-blast device 1 passes the bottom that heat-insulation layer 7 and body of heater 5 are arranged on body of heater 5; Described discharging opening 8 is arranged on the bottom of body of heater 5, and charging aperture 3 is arranged on the top of body of heater 5, and outlet flue 4 is arranged on the top of body of heater 5; It is characterized in that: also comprise screen cloth 2 and some fuel gas inlet 6, be provided with igniter 61 on the sidewall of fuel gas inlet 6; Be provided with filter screen 41 in the described outlet flue 4; Described screen cloth 2 is arranged on the middle and lower part of body of heater 5, and fuel gas inlet 6 passes heat-insulation layer 7 and body of heater 5 is arranged on body of heater 5 inside; At least be provided with three fuel gas inlet 6 on the described body of heater 5; Be provided with two-layer filter screen 41 in the described outlet flue 4, and filter screen 41 from the bottom to top the order number increase gradually.
When fluidized bed furnace carries out the material roasting, at first light the combustion gas that enters from fuel gas inlet 6 with igniter 61, then open air-blast device 1, then material is sent into body of heater 5 from charging aperture 3, material is layered on the screen cloth 2 under action of gravitation, material is under the effect of air-blast device 1, be suspended in the body of heater 5, reach the material of producing required granularity and just can pass through fast screen cloth 2, the material that does not reach the reaction requirement can be blown afloat roasting again by air-blast device 1, the flue gas that roasting process produces is discharged by gas outlet 4, and the gas outlet 4 inner filter screens 41 that arrange can filter out dust and the solid material in the flue gas, avoids the waste of material and to the pollution of environment.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also carry out some improvement to the utility model, these improvement also fall in the protection domain of the utility model claim.
