Embodiment
Spraying plating repair apparatus of the present invention is the device that the carbonization locular wall brick of coke-fired furnace is repaired in spraying plating, has a plurality of pulverizing jets that can change.In this pulverizing jet, the powderject degree of lip-rounding of spraying depositing materials (spraying plating powder) is formed in wherein centre, and a plurality of flame radiation mouths are arranged the radiation mouth row that form in the mode of surrounding this powderject mouth, form at least laterally more than 1 row from the powderject mouth.
And, above-mentioned pulverizing jet contains first pulverizing jet and second pulverizing jet, each flame radiation axis crossover location each other of each flame radiation mouth of above-mentioned first pulverizing jet is on the powderject axis of powderject mouth, and each flame radiation axis crossover location each other of each flame radiation mouth of above-mentioned second pulverizing jet is on the powderject axis of powderject mouth.And the distance of the crossover location each flame radiation axis from the powderject mouth of first pulverizing jet to each flame radiation mouthful is than the distance of the crossover location each flame radiation axis from the powderject mouth of second pulverizing jet to each flame radiation mouthful.Preferred first pulverizing jet is repaired with pulverizing jet as recess and is used, and second pulverizing jet is repaired as be full of cracks portion and used with pulverizing jet.
As described above, repair with in the pulverizing jet at recess, the distance of each flame radiation axis crossover location each other from the powderject mouth to each flame radiation mouth is set to such an extent that repair with the respective distance of pulverizing jet long than be full of cracks portion.Therefore, the surface of carbonization locular wall brick must be thicker with the depositing materials spraying plating from the depositing materials of jetting in narrow and small scope at a distance relatively, is fit to make the repairing of recess damage location planarization.
On the other hand, repair with in the pulverizing jet in be full of cracks portion, the distance setting of each flame radiation axis crossover location each other from the powderject mouth to each flame radiation mouth is to repair with the respective distance of pulverizing jet short than recess.Therefore, the surface of carbonization locular wall brick can be jetted depositing materials thinner from spraying plating depositing materials in the scope of broadness closely relatively, and immerses the melts of spraying plating powder at narrow and small positions such as seam damage location and be full of cracks damage locations.And, do not damage this narrow and small position around flatness.
According to such coating apparatus of the present invention, the shape of corresponding damage location is used the pulverizing jet of a plurality of kinds by difference aptly, can not damage coke-fired furnace carbonization locular wall brick flatness and repair.And, owing to be that spraying plating is repaired, thus with the repairing of the dry seal method of always using relatively, the weather resistance of the carbonization locular wall brick after the repairing is risen.
In spraying plating repair apparatus of the present invention, preferably to repair in the pulverizing jet of usefulness at recess, the crossover location of the flame radiation axis of each flame radiation mouthful is positioned at and repairs more than the powderject mouth 150mm of pulverizing jet of usefulness and the position below the 250mm apart from this recess; Repair in the pulverizing jet of usefulness in be full of cracks portion, the crossover location of the flame radiation axis of each flame radiation mouthful is positioned at apart from this be full of cracks portion and repairs more than the powderject mouth 75mm of pulverizing jet of usefulness and less than the position of 150mm.
The stove width of the carbonization chamber of coke-fired furnace for example is about 400mm, and portion has in vertical direction carbonization locular wall brick to be carried out spraying plating and repairs within it.When the repairing of recess damage location, need be to trickle concavo-convex imitation the (following), promptly, need so-called imitation, and, need adhere to the qualification rate height, and the shape of formed construction body is stable and the little acute triangle of width when the rectilinear direction along wall moves the pulverizing jet of recess repairing usefulness.
On the other hand, when the repairing of the seam damage location or the damage location that vertically chaps, need make the fused powder collide narrower width, on the contrary, in the moving of wall rectilinear direction, must disperse towards periphery with the melts of the melted powder of colliding to wall and constitute stable construction shape, the dull and stereotyped level of the brick around perhaps can not forming and the chap mode of the convex of deviation significantly becomes state near tabular surface.
Therefore, be positioned at by each flame radiation axis crossover location each other that makes each flame radiation mouthful and repair more than the powderject mouth 150mm of pulverizing jet of usefulness and the position of the distance below the 250mm, can form and have the construction body that constitutes the cross section of acute triangle with respect to wall apart from this recess.And, also can repair the pulverizing jet assembling cooling structure of usefulness to recess, repair even under the indoor high-temperature situation of the carbonization of 1200 ℃ of such coke-fired furnaces, also can carry out spraying plating.
In addition, under the situation of above-mentioned distance less than 150mm, becoming is difficult to the construction body that the relative wall stably forms acute triangle.On the other hand, when above-mentioned distance surpasses 250mm, usually, the pulverizing jet that recess is repaired usefulness with contact as other relative carbonization locular walls of the carbonization locular wall of repairing object, can not guarantee above-mentioned distance.And the relative wall carries out the construction of wide cut, has to be difficult to imitate small concavo-convex worry.
In addition, the crossover location of the flame radiation axis of each flame radiation mouthful being positioned at apart from this be full of cracks portion repairs more than the powderject mouth 75mm of pulverizing jet of usefulness and less than the distance of 150mm, is because following reason.
Under the situation of above-mentioned distance, there is the carbonization room temp to be difficult to make the complete fused of the depositing materials with the refractory temperature more than 1200 ℃ to be worried less than 75mm.On the other hand, under above-mentioned distance is situation more than the 150mm, following worry is arranged, promptly, in the inner repairing of optionally filling depositing materials and carrying out of be full of cracks is difficult, the melts of depositing materials does not arrive the innermost of seam pars affecta or be full of cracks pars affecta, and the protuberance on every side of seam pars affecta or be full of cracks pars affecta increases for convex causes the release load of coke.
In spraying plating repair apparatus of the present invention, preferably repair in the pulverizing jet of usefulness at recess, the crossing angle that each flame radiation axis of any 2 flames radiation mouth constitutes each other is below 10 degree, repair in the pulverizing jet of usefulness in be full of cracks portion, the crossing angle that each flame radiation axis of any 2 flames radiation mouth constitutes each other is below 20 degree.
The crossing angle of repairing the pulverizing jet of usefulness at recess surpasses under the situation of 10 degree, and it is big that the expansion of depositing materials becomes, and is difficult to stably form the construction body that is shaped as acute triangle in the vertical cross section of relative wall.
On the other hand, the crossing angle of repairing the pulverizing jet of usefulness in be full of cracks portion surpasses under the situation of 20 degree, following danger is arranged, promptly, the relative wall of carbonization locular wall, the winding-up angle of depositing materials is (too adhering to) excessively, to the be full of cracks inside filling and repairing difficulty that becomes selectively, the melts of depositing materials does not arrive the innermost of seam pars affecta or be full of cracks pars affecta, and protuberance increases for convex causes the release load of coke around seam pars affecta or the be full of cracks pars affecta.
In spraying plating repair apparatus of the present invention, preferably has the distance meter of measuring the recess depths of repairing the position.As the distance meter, for example can use Zaser contourgraph.
This Zaser contourgraph, by be arranged at the powderject mouth near, work as measuring by the powderject Determination of distance device of construction surface.Therefore, in the spraying plating repair apparatus, have under the situation of such Zaser contourgraph, can reliably grasp each pulverizing jet and, when the repairing of recess and be full of cracks portion, can carry out the spraying plating of depositing materials under suitable condition by the distance between the construction surface.
The spraying plating method for repairing and mending of coke-fired furnace of the present invention, have: the recess repair procedure, this recess repair procedure is when injection contains the depositing materials of silicon-dioxide, each flame radiation axis crossover location each other of a plurality of flames that radiated on the jet axis apart from more than the eject position 150mm of depositing materials and on the position of the distance below the 250mm, carry out spraying plating; And be full of cracks portion repair procedure, this be full of cracks portion repair procedure when spraying the depositing materials that the silicon-dioxide amount lacks than the depositing materials of repairing recess, each flame of a plurality of flames that radiated radiate axis crossover location each other on the jet axis apart from carrying out spraying plating more than the eject position 75mm of depositing materials and on the position less than the distance of 150mm.And, about each pulverizing jet, the crossing angle that each flame radiation axis of preferred any 2 flames radiation mouthful constitutes each other be set in respectively with above-mentioned same scope in.
Repair the material of be full of cracks portion, preferably the silicon-dioxide amount than the material of repairing recess lacks.
Specifically, for example, repair the depositing materials of usefulness as recess, can adopt the following material of 100~67 mass percents, the silicon-dioxide amount of this material is about 95 mass percents, and refractory temperature is 1680 ℃, and granularity is less than 0.2mm.
On the other hand, repair the depositing materials of usefulness as be full of cracks portion, can adopt the following material of 100~67 mass percents, the silicon-dioxide amount of this material is 80 mass percents, and refractory temperature is 1450 ℃, and granularity is less than 0.2mm.
The silicon-dioxide amount that makes be full of cracks portion repair the depositing materials of usefulness is repaired the reason that the depositing materials of usefulness lacks than recess and is, if the silicon-dioxide amount is few, correspondingly, refractory temperature descends, the repairing position of the such narrow width of seam damage location or be full of cracks damage location is immersed in the depositing materials easy fusion that becomes easily, and, the depositing materials that is molten to the wall on every side of seam portion damage location and be full of cracks damage location by fusion spreads, and keeps tabular surface easily.
In addition, before the repair procedure of recess or be full of cracks portion, the preferred Zaser contourgraph that uses implements to measure the measurement operation of being repaired the distance between the pulverizing jet of usefulness or the pulverizing jet that usefulness is repaired by be full of cracks portion by construction surface and recess of depositing materials, carries out spraying plating based on measuring result and repairs.And whether at this moment, measuring in the carbonization locular wall has carbon to adhere to, and when judgement has carbon to adhere to, preferably before each repair procedure, implements also to remove to this position winding-up oxygen the operation of carbon elimination.
Carbon adhere to have or not, can confirm by in the spraying plating repair apparatus, carrying area sensors such as CCD camera, cmos sensor.
Under the situation that has carbon to adhere to, though spraying plating depositing materials and repairing, but depositing materials is fixed on the carbonization locular wall insecurely, comes off easily.Therefore,,, can make depositing materials, repair securely reliably attached to the carbonization locular wall by winding-up oxygen and in advance except that carbon elimination at the carbon attachment area.
The spraying plating method for repairing and mending of coke-fired furnace of the present invention in the operation of coke-fired furnace, can be implemented in the carbonization chamber after releasing coke.
Coke-fired furnace has the structure of the carbonization chamber configuration arranged side by side of a plurality of narrow width, in each carbonization chamber, from top loading port loading coal successively, obtains coke in the destructive distillation of carbonization chamber interior.Therefore, because the timing difference of packing in each carbonization chamber, so it is also different to release the timing of coke.
According to the present invention, after releasing the coke after the destructive distillation,, there is no need the situation of picture manual work repairing in the past owing to can carry out the repairing of carbonization chamber at short notice, stop to repair after the operation of coke-fired furnace, can increase substantially the working rate of coke-fired furnace.

In addition, use recess to repair and use pulverizing jet 21B, as shown in Figure 7 and Figure 8, use depositing materials separately and on dull and stereotyped H, carry out spraying plating with pulverizing jet 21A and the repairing of be full of cracks portion.The condition of spraying plating is similarly along on the rectilinear direction of dull and stereotyped H reciprocal 5 times, and constructs 5 layers, and the travelling speed of pulverizing jet is 1m/min.
Repair under the situation of using pulverizing jet 21A at recess, as shown in Figure 7, spraying plating construction body Y1 protuberance is the cross section of mountain shape, short transverse H1=50mm, propagation direction L=45mm.
On the other hand, repair under the situation of using pulverizing jet 21B, as shown in Figure 8, have the spraying plating construction body Y2 that expands thinly to form short transverse H2=8mm, propagation direction L2=110mm on the surface of dull and stereotyped H in be full of cracks portion.
Thus, carry out the spraying plating repairing with pulverizing jet 21B, can confirm that the spraying plating that can suit corresponding to the situation of damage location is repaired by using recess to repair with pulverizing jet 21A and the repairing of be full of cracks portion.
Next, to repair the result as shown in table 4 below using various depositing materials to carry out spraying plating under the situation of spraying plating.
From table 4, depositing materials 2 is applicable to be full of cracks portion repairing usefulness as can be known, and depositing materials 5 is suitable for recess most and repairs usefulness.
[second embodiment]
Below, based on accompanying drawing second embodiment of the present invention is described.
With select a ground in above-mentioned first embodiment and use a plurality of pulverizing jet that can change 20 relative, in the present embodiment, spraying plating repair apparatus 1 is in advance with the pulverizing jet of a plurality of kinds, that is, recess is repaired with pulverizing jet 21A and the repairing of be full of cracks portion and is installed on the last and use of the second pulverizing jet installation portion 13b with pulverizing jet 21B both sides.Recess is repaired to repair with pulverizing jet 21A and be full of cracks portion and is used pulverizing jet 21B, configured in parallel in vertical direction as shown in Figure 9, and still, as long as can bring into play its effect, these pulverizing jets can dispose arbitrarily.
In the present embodiment, do not use pulverizing jet 21B owing to when the recess repair procedure moves to be full of cracks portion repair procedure, do not need to change the recess repairing with pulverizing jet 21A and the repairing of be full of cracks portion, so can further improve operating efficiency.
