In such scheme, seal water system also comprises centering wheel, rotary barrel be circumferentially with described centering wheel, have gap between described centering wheel and described housing, what the described rotary barrel of restriction was taken turns in described centering rocks scope.
In such scheme, described centering wheel is provided with four or six, is evenly distributed on the outside of described rotary barrel.
In such scheme, the diameter of described discrete posticum is 18-22mm, and the diameter in continuous effluent hole is 12-15mm.
In such scheme, the top of described water outlet plate is provided with the first baffle plate of level, and the outside of described housing is provided with vertical second baffle, has gap between described second baffle and the first baffle plate, and the first baffle plate, second baffle and water outlet plate form cooling water buffer district.
In such scheme, described hull outside is provided with L-type plate, and the horizontal section of L-type plate is positioned at below water outlet plate, and the vertical section of L-type plate faces toward the exit end of described water outlet plate.
Implement the seal water system of blast furnace gas in distributor of the present invention, there is following beneficial effect:
Water coolant in cooling channel of the present invention, after discrete posticum and continuous effluent hole, can form cascade to intercept inner blast furnace gas, significantly improve the sealing effectiveness of blast furnace gas between housing and water outlet plate.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the structural representation of the seal water system of blast furnace gas in distributor of the present invention;
Fig. 2 is the part sectioned view of water outlet plate.
Embodiment
In order to there be understanding clearly to technical characteristic of the present invention, object and effect, now contrast accompanying drawing and describe the specific embodiment of the present invention in detail.
Be illustrated in figure 1 the seal water system of blast furnace gas in distributor of the present invention.The rotary barrel 12 that distributor comprises housing 2 and is arranged in housing 2.
Seal water system comprises cooling channel 13, water outlet plate 6 and lower flume 9.Cooling channel 13 is fixed on the outside of rotary barrel 12, the outside of lower flume 9 stationary housing 2, and cooling channel 13 is positioned at top, and lower flume 9 is positioned at bottom.Water in cooling channel 13 is flowed in lower flume 9 by water outlet plate 6.Water outlet plate 6 is horizontally disposed with, and the entrance end of water outlet plate 6 is connected with cooling channel 13.The exit end of water outlet plate 6 also and between housing 2 has gap above lower flume 9.
As shown in Figure 2, water outlet plate 6 inside is provided with the continuous effluent hole 11 of annular and spaced discrete posticum 10, and multiple discrete posticum 10 is also ring-shaped distributed.Be the trumpet-like transition region of convergent between discrete posticum 10 and continuous effluent hole 11, the aperture in the aperture ratio continuous effluent hole 11 of discrete posticum 10 is large.Water coolant in cooling channel 13 flows out formation continuous print cascade 7 through discrete posticum 10 from continuous effluent hole 11, can form cascade 7 to intercept inner blast furnace gas, significantly improve the sealing effectiveness of blast furnace gas between housing 2 and water outlet plate 6.
Further, seal water system also comprises centering wheel 1, rotary barrel 12 be circumferentially with centering wheel 1, gap a is had between centering wheel 1 and housing 2, gap a considers that the characteristic of expanding with heat and contract with cold of material is determined, rock scope by what increase that centering wheel 1 can limit rotary barrel 12, the stability of distributor rotary barrel 12 strengthens greatly.Centering wheel 1 is generally provided with four or six, is evenly distributed on the outside of rotary barrel 12.Because the stability of rotary barrel 12 strengthens greatly, then the minimum clearance d of existing labyrinth seal 14 also can reduce greatly, and the effect of labyrinth seal 14 also significantly improves.
Further, the diameter of discrete posticum 10 is 18-22mm, and the diameter in continuous effluent hole 11 is 12-15mm, can form the cascade 7 of thinner thickness.
Further, the top of water outlet plate 6 is provided with the first baffle plate 3 of level, and the outside of housing 2 is provided with vertical second baffle 4, and have gap b between second baffle 4 and the first baffle plate 3, the first baffle plate 3, second baffle 4 and water outlet plate 6 form cooling water buffer district 5.Gap b is slightly larger than the gap between centering wheel 1 and housing 2.Can under normal circumstances, distributor is inner intercepts blast furnace gas by passing into nitrogen formation pressure-fired, and namely distributor internal pressure is a little more than furnace pressure, enters in blast furnace after now the nitrogen of distributor inside can blow one's water breaks curtain 7.When producing pressure surge in stove, during the pressure of furnace pressure higher than distributor inside, blast furnace gas also can blow one's water breaks curtain 7, now the water coolant that splashes after can storing blast furnace coal air-blowing one's water breaks curtain 7 of the cooling water buffer district 5 of opposing seal.The volume in cooling water buffer district 5 can hold all water coolants forming the front splashing of new nominal situation, to ensure that water coolant does not enter distributor inside.
Further, for preventing water coolant for a long time to the impact of housing 2 sidewall, the sidewall of housing 2 is provided with L-type plate 8, and the horizontal section of L-type plate 8 is positioned at below water outlet plate 6, and the gap between itself and water outlet plate 6 is c, and the vertical section of L-type plate 8 faces toward the exit end of water outlet plate 6.Owing to arranging the enhancing of centering wheel 1 rear cylinder body stability, gap c also can reduce greatly, therefore water coolant flows into lower flume 9 by this gap after the continuous effluent hole 11 on water outlet plate 6 is flowed out, and will form the cascade 7 of thinner thickness to intercept blast furnace gas in this gap area.
By reference to the accompanying drawings embodiments of the invention are described above; but the present invention is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; instead of it is restrictive; those of ordinary skill in the art is under enlightenment of the present invention; do not departing under the ambit that present inventive concept and claim protect, also can make a lot of form, these all belong within protection of the present invention.
