Description
Technical field
The utility model relates to gas washing in SA production field, relates more specifically to a kind of gas washing in SA production fluidizing furnace.
Background technology
Fluidizing furnace is a visual plant in sulphuric acid process, fluidizing furnace is utilized to be extracted by the sulphur composition in sulfurous iron ore again through reaction extracting sulfuric acid exactly, in fluidizing furnace, need sulfurous iron ore Thorough combustion to generate sulfur dioxide gas on the one hand, high temperature on the other hand in fluidizing furnace can produce certain impact to body of heater and burner hearth again, the particularly slag-drip opening of body of heater, this slag-drip opening usually burns out due to the impact of high temperature, cause the slag of high temperature easily to leak from slag-drip opening, bring potential safety hazard to production.
Utility model content
The purpose of this utility model is to provide the gas washing in SA production fluidizing furnace of a kind of mud hole at high temperature also not rapid wear, and the technical scheme realizing above-mentioned purpose is as follows:
A kind of gas washing in SA production fluidizing furnace, comprise fluidizing furnace body, the below of fluidizing furnace body sets out cinder hole, it is characterized in that: described residue outlet is the bend pipe structure of bending simultaneously, wherein one end of residue outlet is arranged in scum hole, the other end forms slag notch, the internal diameter of scum hole is greater than the external diameter of residue outlet, gap is formed between scum hole and residue outlet, the surrounding of gap location lays refractory brick, the refractory brick be wherein positioned at below scum hole is the wedge shape refractory brick extended in the horizontal direction, the upper limb of described wedge shape refractory brick extends to form wedge point to away from residue outlet side, the angle of described wedge point is 45-60 degree, the thickness of described wedge shape refractory brick is 30-50cm.
Preferably, residue outlet is close in the upper surface of described wedge shape refractory brick.
Preferably, also comprise the dispersion plate of the bottom being positioned at fluidizing furnace body, be evenly spaced apart between dispersion plate and be provided with multiple pore.
Preferably, also comprise gas inlet, the bottom of described fluidizing furnace body 1 is for falling isosceles trapezoidal structure, and form space between the bottom of described dispersion plate and fluidizing furnace body, gas inlet is then opened in the bottom of fluidizing furnace body and is communicated with space.
The utility model structure is simple, the long service life of slag notch and residue outlet.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram;
Figure number illustrates: fluidizing furnace body 1, residue outlet 2, slag notch 3, refractory brick 4, wedge shape refractory brick 5, dispersion plate 6, pore 7, space 8, gas inlet 9.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In figure, gas washing in SA production fluidizing furnace, comprise fluidizing furnace body 1, the below of fluidizing furnace body 1 sets out cinder hole, described residue outlet 2 is the bend pipe structure of bending, wherein one end of residue outlet 2 is arranged in scum hole, the other end forms slag notch 3, the internal diameter of scum hole is greater than the external diameter of residue outlet 2, gap is formed between scum hole and residue outlet 2, the surrounding of gap location lays refractory brick 4, the refractory brick be wherein positioned at below scum hole is the wedge shape refractory brick 5 extended in the horizontal direction, fluidizing furnace body is close to by the refractory brick at other positions, and use common refractory brick 4.The upper limb of wedge shape refractory brick 5 extends to form wedge point to away from residue outlet side, and the angle of wedge point is 45-60 degree, and the thickness of wedge shape refractory brick is 30-50cm.
Dispersion plate 6 is positioned at the bottom of fluidizing furnace body 1, dispersion plate 6 is evenly spaced apart and is provided with multiple pore 7, the bottom of fluidizing furnace body 1 is for falling isosceles trapezoidal structure simultaneously, so make between the bottom of dispersion plate 6 and fluidizing furnace body 1, to form very large space 8, gas inlet 9 is then opened in the bottom of fluidizing furnace body 1, be communicated with space 8, contribute to the flowing of air, in the utility model, the lower surface of wedge shape refractory brick and dispersion plate 6 are close to, and upper surface and the residue outlet of wedge shape refractory brick are close to.
Adopt such structure that hot-fluid can be guided away from slag notch, effectively can reduce the temperature of slag notch like this, therefore slag notch is not easy to be burned, and improves the wearing quality of fluidizing furnace.
So far, those skilled in the art can understand that the technical solution of the utility model implemented by this specification sheets, therefore repeats no more.
These are only the preferred embodiment of the utility model embodiment; not in order to limit the utility model embodiment; within all spirit in the utility model embodiment and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included in the protection domain of the utility model embodiment.
