Below, with reference to accompanying drawing, embodiment of the present utility model is specifically described.Fig. 1 is the longitudinal section that the wet collector (secondary particle collector) in the related converter waste gas treatment facility of embodiment of the present utility model is shown.For this secondary particle collector 5A, its housing 30 is tubular basically, and it axially is set to vertically.In addition, this secondary particle collector 5A replaces the secondary particle collector 5 of converter refining equipment shown in Figure 4 and the particle collector of configuration, by the converter waste gas that a particle collector 3 is removed after thick dust, from upper end, is supplied with.The waste gas of discharging from the elbow separator 39 of the bottom that is arranged at housing 30 of the secondary particle collector of present embodiment in addition, is sent to T-valve 9 by fan 8.
As shown in Figure 1, in the housing 30 of the secondary particle collector 5A of present embodiment, be provided with at an upper portion thereof internal diameter diminishing reducing diameter part 30a downwards; And the minor diameter part 30b of the internal diameter minimum of the bottom of reducing diameter part 30a, and then thereunder be provided with the wide diameter portion 30c that internal diameter enlarges gradually downwards.And, in the inside from this reducing diameter part 30a to the housing of wide diameter portion 30c, be provided with flashboard 31.This flashboard 31 and the suspension bracket hanging of the top of identical (with reference to Fig. 5) slave unit in the past, this flashboard 31 utilize the axle support etc. of the inside of housing 30 to locate to be located at the center of housing.And, flashboard 31 via axle 20(with reference to Fig. 5) and by cylinder 28(with reference to Fig. 5) on vertical direction, drive, flashboard 31 is by utilizing this cylinder 28 to move along vertical direction, adjusts the aperture of internal surface of the part from reducing diameter part 30a to wide diameter portion 30c of itself and housing 30.In addition, although the converter waste gas of having removed thick dust by particle collector supplies in housing 30 from the top of housing 30, but above the flashboard 31 in housing 30, be provided with the atomiser nozzle 21(of injection water with reference to Fig. 5), water sprays to the interior converter waste gas of housing 30 that supplies to the secondary particle collector from nozzle 21.
It is conical that this flashboard 31 is, and between the internal surface of its cone surface and wide diameter portion 30c, with roughly certain interval, isolates.And, the converter waste gas that has added water from nozzle 21 via the internal surface of wide diameter portion 30c and the cross section between flashboard 31 in the form of a ring path and arrive water separated part 32.In water separated part 32, housing 30 is formed with from wide diameter portion 30c towards the continuous cylindrical portion 30d in vertical below, in the inside of this cylindrical portion 30d, is provided with the cylindraceous gas passage portion 33 coaxial with cylindrical portion 30d.And cradle portion 34 along the circumferential extension of housing 30 with gas passage portion 33, and is extended in the mode that the horizontal direction to housing tilts between the outside surface of the internal surface of housing 30 and gas passage portion 33.And the part in the deep of the vergence direction that is positioned at this cradle portion 34 of housing 30 is provided with the water that will contain dust and is discharged to the relief outlet 35 outside housing 30.In addition, the interval between the internal surface of the wide diameter portion 30c of the cone surface of flashboard 31 and housing 30 may not be certain, can become greatly or on the contrary and diminish gradually downwards.This interval can be by the mobile unit as flashboard 31 the control of cylinder 28 adjust, for example, can in the scope of 10mm～160mm, adjust.If interval, less than 10mm, can hinder the circulation of fluid, if surpass 160mm, the mixing efficiency of the dust in water and waste gas will reduce.
On the other hand, gaseous constituent is sent to the mist separated part 36 of the lower side that is arranged at water separated part 32 via gas passage portion 33.In mist separated part 36, to be held on its gas, by the mode in zone, be provided with the rotating paddle 37 of the mobile rotation that makes gas.Below this rotating paddle 37, be provided with for the drip cradle portion 38 of mist of periphery of internal surface of housing of recovery, the mist that drips via this cradle portion 38 is exported hull outside by relief outlet 39.In addition, be arranged at the structure of cradle portion 38 of mist separated part 36 with to be arranged at the cradle portion 34 of water separated part 32 roughly the same.
Via the converter waste gas of mist separated part 36, arrive the elbow separator 40 of the below that is arranged at housing 30, utilize the mist in the further gas recovery of mist collecting part 41 that is arranged in this elbow separator 40.The bending of this mist collecting part 41 and elbow separator 40 is accordingly towards the bending of gas circulating direction, thus its leading section turn back and can collect the mist that has liquefied, the liquefaction mist is discharged from the opening 42 that is arranged at this return portion.Together with the liquefaction mist of the liquefaction mist of discharging from this opening 42 and the internal surface transmission along elbow separator 40 decline, from relief outlet 43, discharge.
The waste gas of having removed mist via elbow separator 40 is sent to the T-valve 9(of rear operation with reference to Fig. 4).The water that contains dust of discharging from relief outlet 35,39,43 on the other hand, is sent to the continuous sedimentation thickener via water seal arrangement shown in Figure 2 51.This water seal arrangement 51 can arrange separately at each relief outlet 35,39,43, also relief outlet 35,39,43 can be concentrated and a water seal arrangement 51 is set.Water tank at water seal arrangement 51 stores water, and the end of the pipe arrangement 50 that is connected with the resistance to air loss such as relief outlet 35 impregnated in the water in water seal arrangement 51.And the water that overflows from the water tank of this water seal arrangement is collected in water recoverer 52, and then utilizes pump 53 that the water in water recoverer 52 are given to the continuous sedimentation thickener.By this continuous sedimentation thickener, the dust solid state in water is also reclaimed.Be stored in the depth of water of water of water tank of water seal arrangement 51 for example for 2500mm.The hydraulic pressure of pipe arrangement 50 lower ends is higher than the pressure of the gas in housing 30.Therefore, the gas in the housing 30 of secondary particle collector is cut off by water seal arrangement 51, and converter waste gas can not flow out from relief outlet 35,39,43.
In addition, in the secondary particle collector of present embodiment, mist of for example mist separated part 36(beyond water separated part 32 separates) and elbow separator 40(secondary mist separate) structure not from the past different, can adopt various structures.
Next, the action of the secondary particle collector 5A of the present embodiment that forms as mentioned above described.From atomiser nozzle 22(with reference to Fig. 5) to by particle collector, having been removed the converter waste gas injection water of thick dust, then this converter waste gas collides flashboard 31 with the state that has added water.At these flashboard 31 place's housing 30 undergauges, channel narrows by reducing diameter part 30a gas and water, by minor diameter part 30b gas and water, enter into the internal surface of housing 30 and the gap of the ring-type between flashboard 31, by wide diameter portion 30c gas and water, flow through the internal surface of this housing 30 and the gap of the ring-type between flashboard 31 downwards.At this moment, because the dust in converter waste gas (control of dust after fine dust) flows through described gap together with water, therefore fully be blended in water, thereby dust is incorporated in water.Although the circulation that also has waste gas is balanced with the water yield, if the water yield is abundant, the mixed stream by water and waste gas flows through described gap, and the dust in waste gas can almost all be transferred in water and be mixed in water.
And, following situation that the result of the simulation by inventor etc. is clear and definite: as shown in Figure 3, mixed stream by the water after flashboard 31 and waste gas, under the state in the gap between the internal surface that has flow through flashboard 31 and housing 30, is kept intact mobile downwards along the internal surface of housing 30.In the left figure of Fig. 3, the lower surface identical with Fig. 1 of flashboard 31 is smooth, and in the right figure of Fig. 3, the lower surface of flashboard 31 swells downwards, and be crooked projectedly downwards on longitudinal section.In the situation that the lower surface of flashboard 31 be shaped as any, the mixed stream that flow out below from from the gap between the internal surface of flashboard 31 and housing 30 to flashboard 31 all after along the internal surface of housing 30, be layeredly and move below housing 30 in for some time, the amount of lower face side that is rolled into flashboard 31 is few.That is to say, the below of mixed stream along the internal surface of housing 30 to housing 30 is layeredly moves, and irrelevant with the shape of the lower surface of flashboard 31.
In the utility model, water separated part 32 is arranged at the below of flashboard 32, and this water separated part 32 is collected the water that flows along the internal surface of housing 30 downwards and also this water is discharged to outside housing.Water separated part 32 utilize housing 30 the below that is arranged at flashboard 31 cylindrical portion 30d and between itself and gas passage portion 33, form two layered cylinder, the cradle portion 34 that the oriented relief outlet 35 of the region division of the ring-type between cylindrical portion 30d and gas passage portion 33 tilts.The water that contains dust transmits downwards and is tackled by cradle portion 34 along the internal surface of the cylindrical portion 30d of housing 30, to relief outlet 35, moves, and outside housing 30, is recovered.
Like this, at flashboard 31, with high blend level, having mixed the water of dust is tackled and reclaims by the cradle portion 34 of the water separated part 32 that arranges under flashboard 31, and be discharged to outside housing 30, the dust of therefore delivering to the waste gas of mist separated part 36 and elbow separator 40 from gas passage portion 33 becomes few.That is, can utilize water separated part 32 from converter waste gas, to reclaim dust expeditiously.
The waste gas below gas passage portion 33 is delivered to, contain mist, in this mist, still contain dust.Therefore, in the utility model, for the mist by waste gas, be discharged to the below that the outer mist separated part 36 that also reclaims of housing 30 is arranged at water separated part 32.In mist separator 36, the mobile rotation that rotating paddle 37 makes to contain the gas of mist applies centrifugal force, thus mist is removed from waste gas, and further mist is reclaimed and removes from waste gas by elbow separator 40.
And, from the water of relief outlet 35 discharges and the liquefaction mist of discharging from relief outlet 39,43, via water seal arrangement 51, be sent to the continuous sedimentation thickener, by the continuous sedimentation thickener, will and be concentrated from the contained dust of liquefaction mist that relief outlet 39,43 is discharged from the water of relief outlet 35 discharges, and solid state recovery.
Therefore, the converter waste gas of delivering to T-valve and waste gas recoverer from the secondary particle collector, contain hardly dust.The ratio that for example, can make to deliver to the dust in the converter waste gas of this waste gas recoverer drops to 10mg/Nm
3(1Nm
3Gas in dust be 10mg), can access extremely high dust collecting efficiency thus.Consider: in existing wet collector, this dust collecting efficiency is at most 40mg/Nm as mentioned above
3But, this be due to temporarily be blended in water dust after flow to elbow separator during again from water, separate and turn back to gas.As the utility model, by near will collect dust under flashboard 31 water, as mixed stream, reclaim, dust can, from water, turning back in gas, can not improve dust collecting efficiency thus.
In addition, the utility model is not limited to above-mentioned embodiment, can carry out various distortion.For example, the cradle portion 34 that the mixed stream of near the water that flows through shell inner surface and waste gas is reclaimed can be arranged at the cylindrical portion 30d that extends from the lower end of wide diameter portion 30c downwards like that not as above-mentioned embodiment, and is arranged at wide diameter portion 30c midway.Thus, by under flashboard 31, namely near the position of flashboard 31, reclaim mixed stream, can further improve dust collecting efficiency.In addition, although housing 30 shrinks at the allocation position of flashboard 31, length and the angle of inclination of reducing diameter part 30a, minor diameter part 30b and wide diameter portion 30c are arbitrarily.
In addition, in the above-described embodiment, although the situation that wet collector of the present utility model is applied to the secondary particle collector of converter waste gas treatment facility is illustrated, but the utility model is not limited to this, the utility model also can be applied to be arranged on the wet collector of field Deng De factory of department of chemistry and equipment etc., is used for reclaiming the dust in waste gas.
