Below, based on the castoff processing system that useless printed base plate is handled preferred implementation of the present invention is described.In the present invention, discarded object is useless printed base plate (comprising waste products, out-of-date lotout product), it is following structure: the printed circuit wiring that sets the valuable metal that has used gold, copper etc. on the substrate that obtains with the hardening of resin glass fibre, and then, installed and used the capacitor of valuable metal of gold, silver, copper, platinum etc. or binding post etc.
As shown in Figure 1, castoff processing system 1 have the breaker 2 of broken useless printed base plate, quantitatively transport the weigh feeder 3 of for example belt feeder etc. of broken thing broken in breaker 2, as the quenching apparatus 6 of the after burner 5 of the rotary furnace device 4 of an example of the primary combustion device of the broken thing of burning, exhaust that burning produces in rotary furnace device 4, exhaust that chilling burns in after burner 5.And then the exhaust that have the bag type filtering apparatus 7 that separates flying dust from the exhaust of cooling, will remove flying dust is discharged to the chimney 8 in the atmosphere.Be provided with the hydrolock conveying device 10 of the residue thing after conveying is burnt in rotary furnace device 4 in the bottom of after burner 5.
As shown in Figure 2, rotary furnace device 4 has rotatable furnace main body 20 roughly cylindraceous, makes the drive division 21 of furnace main body 20 rotation.Furnace main body 20 is so that length direction is equipped with towards the mode of transverse direction, and inner cavity becomes primary zone 22.The inner surface of furnace main body 20 covers by having acid resistance and stable on heating material.One end of furnace main body 20 is provided with the wall portion 23 of the end of inaccessible furnace main body 20, and the other end of furnace main body 20 is connected in the side of the furnace main body 51 of after burner 5 described later, and at furnace main body 51 inner openings.Between the end of furnace main body 20 and wall portion 23, have not shown sealing mechanism.Between the outer peripheral face of furnace main body 20 and furnace main body 51, also have sealing mechanism 24 again.And, can come revolving burner main body 20 with respect to fixing wall portion 23 and furnace main body 51 between the end of sealed furnace main body 20 and the wall portion 23 and under the outer peripheral face and the state between the furnace main body 51 of furnace main body 20.In addition, furnace main body 20 be preferably with from wall portion 23 sides along with the mode that tilts towards open end side and a little downwards is equipped with, for example can tilt about about 1～5 ° to get final product with respect to horizontal direction.Like this, then can make the broken thing that supplies in the combustion chamber 22 from broken thing supply port 31 described later successfully move to the open end side that disposes than the lowland.
On the outer peripheral face of furnace main body 20, be fixed with roughly circular all gears 25 and roughly circular rubber-tyred roller 26,26.Below furnace main body 20, have and to contact on one side a plurality of supporting rollers 27 of rotation respectively on one side with each rubber-tyred roller 26.The motor 29 that drive division 21 had and was formed on the pinion 28 of the gears engaged on the outer peripheral face of all gears 25 and makes pinion 28 rotations.That is, if CD-ROM drive motor 29, then pinion 28 rotations are accompanied by the rotation of pinion 28, and all gears 25 also rotate.And furnace main body 20 rotates integratedly with all gears 25.Supporting roller 27 makes rubber- tyred roller 26,26 rotations of rotating integratedly with furnace main body 20 on one side, on one side rubber- tyred roller 26,26 is led, thereby support furnace main body 20 from the below by rubber-tyred roller 26,26.In addition, the rotating speed of motor 28 and direction of rotation, promptly the rotating speed of furnace main body 20 and direction of rotation are variable, thereby in the burning processing, also can regulate rotating speed and direction of rotation corresponding to the fired states in the combustion chamber 22.
The broken thing of useless printed base plate is supplied to broken thing supply port 31 in the combustion chamber 22 in 23 upper sheds of wall portion.On broken thing supply port 31, be connected with broken thing feed path 32.Broken thing feed path 32 with more towards broken thing supply port 31 sides just more the mode towards the below tilt, broken thing utilization is from focusing on downhill race in the feed path 25, thereby supplies to broken thing supply port 31.As shown in Figure 1, the inlet at broken thing feed path 32 has the hopper 33 that is used for temporarily storing broken thing.Be folded with baffle plate 34 between the inlet of the outlet that opens and closes hopper 33 and broken thing feed path 32 again.In addition, broken thing feed path 32, hopper 33, baffle plate 34 connect continuously with respect to the atmosphere in the combustion chamber 22, heat by the heat transfer that comes from combustion chamber 22.Therefore, the broken thing in hopper 33, the broken thing feed path 32 was preheated before supplying to combustion chamber 22.
Again, wall portion 23 is provided with burning gases is supplied to burner 41 in the furnace main body 20.Burner 41 is to be equipped with in the mode of spray combustion gas along the length direction of furnace main body 20 and on the direction that tilts with respect to the direction of approximate horizontal.In addition, broken thing supply port 31 is preferably than burner 41 and more is positioned at the top.If like this, then the broken thing that falls from broken thing supply port 31 before the bottom that drops to combustion chamber 22 just with just spray from burner 41 after burning gases contact and be heated, so can promote the burning of broken thing.With this, just can suppress because of the temperature difference between the furnace main body 20 of the broken thing supplied with and high temperature cause to the bad influence of furnace main body 20 or because of the broken thing supplied with and be piled up in the heat transfer inequality that the temperature difference between the interior broken thing in combustion chamber 22 causes.
And then wall portion 23 is provided with the air supply port 42 that supplies air in the combustion chamber 22.Air supply port 42 is opening above broken thing supply port 31 for example.
The flow of the air of supplying with from above-mentioned air supply port 42 and to supply to the flow of the fuel oil the burner 41 variable respectively.Promptly, the supply flow rate by regulating air or the output of burner 41 just can be regulated temperature in the combustion chamber 22 or air ratio (use for oxidation package fully is contained in the required theoretical amount of oxygen of carbon component in the broken thing and come the value that obtains divided by the amount of oxygen of reality importing).With this, just can will be maintained oxidizing atmosphere in the combustion chamber 22.
In addition, if in oxidizing atmosphere, burn broken thing, then can from the residue thing, reduce Br (bromine) effectively.Fig. 3 is the result of experiment that present inventors carried out with regard to combustion efficiency, be the heat treated time of the broken thing of expression and be contained in heat treated after the residue thing in the amount (hot igloss value) of Br between the chart of relation.As can be seen from Figure 3, compare with the situation of the broken thing of thermal decomposition in reducing atmosphere, under the situation of in oxidizing atmosphere, burning, compare with the situation (air supply flow rate 9L/min) that reduces air ratio again, under the situation (air supply flow rate 18L/min) that increases air ratio, the volatilization of Br is rapid, and the amount of the Br of final residue in the residue thing is few.Thereby, with the mode that in oxidizing atmosphere, the improves air ratio broken thing that burns, just can promote the reduction of the Br in the residue thing with this.
As shown in Figure 1, after burner 5 has the roughly rectangular-shaped furnace main body 51 that for example forms lengthwise.Furnace main body 51 is equipped with length direction under the state that makes the sidewall approximate vertical vertically, again.The inwall of furnace main body 51 is for example by formation such as bricks, and the inner surface of furnace main body 51 is for having acid resistance, stable on heating structure.And the inboard of this furnace main body 51 becomes secondary combustion chamber 52.On a sidewall 51a of furnace main body 51, be formed with the opening of the circular of the end of supporting described furnace main body 20, in this opening, be inserted with the open end of furnace main body 20.The end of furnace main body 20 is inserted into the inboard from the inner surface of sidewall 51a.That is, in combustion chamber 22 after the broken thing of burning gas, the flying dust in remaining residue thing (slag) or the combustion chamber 22 import to reliably in the combustion chamber 52 from the openend of furnace main body 20.Be provided with the residue thing outlet 53 that is connected on the hydrolock conveying device 10 in the bottom of furnace main body 51 again.The residue thing that is discharged to the combustion chamber 52 from combustion chamber 22 is discharged to the hydrolock conveying device 10 from residue thing outlet 53.
As shown in Figure 4, hydrolock conveying device 10 have the case 61 of storing cooling water, with the scraping plate transmission mechanism 62 that is equipped in the case 61.Residue thing outlet 53 impregnated in the cooling water in the case 61, seals by cooling water, thus the inflow of the outer gas of blocking.Be formed with on the case 61 have from storage the bottom of cooling water 61a towards above the rake 61b that tilts, the upper end of rake 61b is provided with the outlet 63 of discharging the residue thing.Scraping plate transmission mechanism 62 have a pair of ring- type chain 65,65, and be arranged at 65,65 on chain a plurality of scraper plates 66, with a plurality of rollers 67 of support chain 65,65.Chain 65,65 mutual almost parallel ground configuration is wound on a plurality of rollers 67, is accompanied by the rotation of roller 67 and the complete cycle motion.Scraper plate 66 is along the direct of travel of chain 65,65 and be provided with every predetermined distance ground.And, advance in such a way: be accompanied by the complete cycle motion of chain 65,65, advance towards rake 61b from bottom 61a, rise on the water surface at rake 61b, move to again on the outlet 63, afterwards once more from rake 61b towards bottom 61a, and turn back in the water.In such structure, from the residue thing that residue thing outlet 53 is discharged, be deposited in the cooling water in the case 61, scrape by scraper plate 66 in the bottom of bottom 61a and get and from cooling water, raise up, upper end at rake 61b drops to the outlet 63 from scraper plate 66, thereby discharges from case 61.The residue thing aggregation of discharging from outlet 63 is in enveloping field 68.
If make the residue thing by cooling water like this, then residue thing cooling, and be contained in water soluble salt, bromine (Br), chlorine (Cl), sulphur (S) in the residue thing and become to grade and be dissolved in the water, from the residue thing, separate.Fig. 5 is the result of experiment that present inventors carried out with regard to the washing effect of residue thing, is the chart of the relation between the residual concentration of Br, Cl, S in burning processing time and the residue thing that is contained in after the burning processing of the broken thing of expression.Relatively represented after the burning each residual concentration under the not situation of rinsing residue thing and the situation of having washed the residue thing again.As can be seen from Figure 5, Br, the Cl in the residue thing, S can reduce by handling after washing in burning.Thereby, by rinsing residue thing in hydrolock conveying device 10, just can under the state of the harmful substance that has reduced Br, Cl, S etc., reclaim.
As shown in Figure 1,52 derive the export mouth 71 of gases from the combustion chamber in the upper shed of the upper end of furnace main body 51.In illustrated example, export mouth 71 be arranged on the opposed side 51b of sidewall 51a on.Being connected with on export mouth 71 derives passage 72.The outlet of deriving passage 72 is connected on the quenching apparatus 6.
And then on furnace main body 51, have a plurality of air supply ports 81 that supply air in the combustion chamber 52.In illustrated example, air supply port 81 is provided with up and down respectively on opposed 2 sidewall 51a, the 51b of furnace main body 51 side by side.On sidewall 51a, be arranged at than the end of furnace main body 20 and more lean on the top, on sidewall 51b, be arranged at than export mouth 71 more by the below.Again, as shown in Figure 6, on each sidewall 51a, 51b, air supply port 81 from the combustion chamber 52 central side see along the edge portion in left side and be provided with side by side up and down.That is, being disposed at central part with combustion chamber 52 when the top is seen is center and on the mutual point-symmetric position.Air from sidewall 51a (51b) air supply port 81 arranged side by side up and down to mutual almost parallel towards injection.Again, when 52 central side is seen from the combustion chamber, air from the combustion chamber 52 center towards leftwards spraying.In such structure, if air is supplied in the combustion chamber 52 from each air supply port 81, then the atmosphere in the combustion chamber 52 stir by the air of supplying with, and are center and the air-flow of rotation counterclockwise thereby formed central part with combustion chamber 52 when the top is seen.If like this, combustion-gas flow reliably just, again, the volume that can effectively utilize combustion chamber 52 comes combustion-gas flow.In addition, the position of air supply port 81 or towards being not limited thereto, for example air flows along the inner surface of furnace main body 51 and also can.If like this, just form along the air gas curtain of the inner surface of furnace main body 51, be attached on the inner surface of furnace main body 51 thereby can prevent to refine slag or residue thing etc.Again, each the bight upper shed air supply port 81 on being formed between each internal face of furnace main body 51 also can.Under this situation, also can prevent to refine slag or residue thing etc. and be attached on the bight of furnace main body 51.
Again, as shown in Figure 1, furnace main body 51 is provided with burning gases is supplied to burner 82 in the combustion chamber 52.In illustrated example, burner 82 is arranged on the sidewall 51a, above the openend of furnace main body 20, disposes near the mode of the spray combustion gas openend of furnace main body 20.If like this, then burning gases are mixed into the exhaust after just importing, thereby can burn efficiently from openend.Again, in illustrated example, the injection direction of burning gases disposes in the mode with the injection direction almost parallel of the air that comes from the air supply port 81 that is provided on the sidewall 51a.In addition, burner 82 preferably is configured to more lean on the top than at least 1 air supply port 81, again, preferably is disposed between each air supply port 81.If like this, then burning gases can be supplied between the swirling eddy, thereby can burn swirling eddy efficiently.
In addition, the flow of the air of supplying with from air supply port 81 and to supply to the flow of the oxygen the burner 82 variable respectively.That is, the supply flow rate by regulating air or the output of burner 82 just can be regulated the interior temperature in combustion chamber 52 or the speed of air-flow.Again, having the structure of controlling the temperature of exhaust automatically by reponse system on after burner 5 also can.For example make to become the thermometer of the temperature that the exhaust that is determined at export mouth 71 is set, regulate this structure of flow that supplies to the fuel oil in the burner 82 based on the temperature measuring value of this exhaust, the mode that becomes desired value with this temperature measuring value is carried out FEEDBACK CONTROL and is got final product.
As shown in Figure 1, quenching apparatus 6 has for example has the roughly cooling tower main body 91 of the lengthwise of sidewall cylindraceous, and the inside of cooling tower main body 91 becomes cooling chamber 92.The ceiling face of cooling tower main body 91 form from central portion along with towards circumference and diameter become the big roughly frustum of a cone towards the below planar.To import to gas introduction port 93 in the cooling chamber 92 at the gas of combustion chamber 52 internal combustion at the central portion opening of ceiling face.On gas introduction port 93, be connected with the outlet of described derivation passage 72.Again, gas export mouth 93 is provided with the cowling panel 95 that is used for rectification gas.
As shown in Figure 7, cowling panel 95 has for example 4 of multi-discs.It is tabular that each cowling panel 95 forms Boping, for example forms elongated rectangular portion 95b respectively from opposed 2 bights of the diamond-shaped portion 95a of almost diamond and extend and be arranged at this shape of both sides.The both ends of rectangular portion 95b be fixed in respectively the roughly columned support 96 on the central portion that is arranged on gas introduction port 93 outer peripheral face, with the inner peripheral surface of gas introduction port 93 on.And, be equipped with in the mode that is radial extension from support 96 along radial direction.Angle between each rectangular portion 95b of each cowling panel 95 forms angle about equally.Again, each cowling panel 95 is equipped with obliquely with respect to vertical direction.The incline direction of each cowling panel 95 is regarded as from the center of gas introduction port 93 and is roughly the same angle of inclination.In illustrated example, see from the top with along with towards center being the clockwise direction at center and the mode that tilts is equipped with downwards with gas introduction port 93.Thereby if exhaust is flowed towards ground, below from the top of each cowling panel 95, then exhaust is flowed along the incline direction of cowling panel 95, along clockwise direction towards outer circumferential side on one side descend on one side.Like this, just can be with exhaust on one side along of the mode rectification of clockwise direction rotation one side towards cooling chamber 92.Again, exhaust can be from cowling panel 95 the ceiling face along cooling tower main body 91 or near the of medial surface flow.If such words, then the ceiling face of cooling tower main body 91 or medial surface heat up by the exhaust of the high temperature after just importing from gas introduction port 93.That is, can prevent that the ceiling face of cooling tower main body 91 or the temperature of medial surface from too reducing, thereby can suppress to refine on the ceiling face or medial surface of slag attached to cooling tower main body 91.
As shown in Figure 1, in cooling chamber 92, be provided with and spray as the liquid of the cooling usefulness cooling water supply port 100 of water for example again.In illustrated example, cooling water supply port 100 is equipped with a plurality of in the ceiling portion of cooling tower main body 91 in the mode on every side of surrounding gas introduction port 93.Cooling water sprays from each cooling water supply port 100 vaporificly.Again, the injection direction of each cooling water supply port 100 be preferably towards oblique below, promptly along being center and the identical for example clockwise direction of direction of rotation mutually when the top is seen for example with gas introduction port 93.Under this situation,, then stir the atmosphere in the cooling chamber 92, thereby the central portion that forms with cooling chamber 92 is the spiral helicine down current at center if spray cooling water from each cooling water supply port 100.If like this, then the stream of the gas in cooling chamber 92 is elongated, thereby can make the long-time rotation of gas and cooling fully.That is, can use the volume of cooling chamber 92 to come refrigerating gas effectively.Can suppress to refine on the inner surface of slag attached to cooling tower main body 91 again.
The emitted dose that comes from the cooling water of above-mentioned cooling water supply port 100 is variable, suitably regulates in the mode of exhaust chilling in cooling chamber 92.If coolant exhaust can prevent that then the composition that decomposes by the burning in combustion chamber 52 is synthetic more hastily.Particularly, if be cooled to hastily be not easy to produce below the synthetic again temperature (about about 300 ℃) of dioxin, then can prevent the synthetic again of dioxin.In addition, having in quenching apparatus 6 by feedback is that the structure of controlling delivery temperature automatically also can.For example make to become the thermometer of the temperature that the exhaust that is determined at export mouth 111 described later is set, regulate this structure of supply flow rate that supplies to the cooling water in the cooling water supply port 100 based on the temperature measuring value of this exhaust, the mode that becomes desired value with this temperature measuring value is carried out FEEDBACK CONTROL and is got final product.
Be provided with the conduit 110 of deriving the gas in the cooling chamber 92 in the bottom of cooling chamber 92.Conduit 110 tilts in the mode that rises towards the sidewall of cooling tower main body 91 from the lower central of cooling chamber 92, connects sidewall and extend to be set to the outside.The lower central portion place of the inlet of conduit 110 in cooling chamber 92 is towards lower opening.This inlet becomes the export mouth 111 of deriving the gas in the cooling chamber 92, and the inside of conduit 110 becomes derives passage 112.

Bag type filtering apparatus 7 is for being provided with a plurality of structures that have the bag filter 131 of filter cloth in housing 130.The outlet of deriving passage 112 is connected on the introducing port 132 on the lower sidewall that is arranged on housing 130.Import to gases in the housing 130 from introducing port 132 and flow into the inboard from the outside of bag filter 131, discharge from the export mouth 133 of the top that is arranged at bag filter 131 again through filter cloths.Export mouth 133 is connected on the chimney 8 via passing away 135.The flying dust of catching in the outside of bag filter 131 is discharged from the outlet 141 on the bottom that is arranged at housing 130.
Again, have the flying dust that storage discharges from outlet 141 flying dust storagetank 150, with the heavy metal immobilization material that flying dust, adds liquid chelating agent etc., water etc., carry out that heavy metal is fixed and the evenly mixing device of damping 151.
The refuse processing method of the castoff processing system 1 that constitutes like that more than having used then, is described.At first, the printed base plate that will give up supplies in the breaker 2, is broken for acinous.The mode of the size about fragmentation for example becomes below about 10mm with particle diameter gets final product.Become granuliform broken thing and supply to weigh feeder 3 from breaker 2.And, transport while regulate quantities delivered (weight or volume), and be stored in the hopper 26 by weigh feeder 3.If stored the broken thing of predetermined weight or volume in hopper 26, then open baffle 34.Broken thing supplies in the combustion chamber 22 from supply port 22 through feed path 25.Again, broken thing is preheated in hopper 33, broken thing feed path 32 by the heat transfer that comes from combustion chamber 22.
In rotary furnace device 4, by the driving of drive division 21, furnace main body 21 for example rotates with the rotating speed about about 0.1rpm～1.0rpm.Again, supply with the burning gases of high temperature from burner 41, the atmosphere in the combustion chamber 22 for example be heated near the openend about more than 900 ℃ about.When in putting into combustion chamber 22, broken thing falls in the mode of sowing from broken thing supply port 31, and then heats by the burning gases that spray from burner 41.With this, promoted the burning of broken thing, superfine particulate oxidation fully in the whereabouts in the broken thing.Like this, broken thing heated fully by the burning gases of the preheating in hopper 33, the broken thing feed path 32, burner 41 before the bottom that drops to furnace main body 20.If like this, the broken thing of supply and the temperature difference of furnace main body 20 just diminish, thus the thermal stress that the reason temperature difference produced and the harmful effect to furnace main body 20 that causes just tails off.And then, because the broken thing of supply and the temperature difference that is deposited in the broken thing in the combustion chamber 22 are tailed off,, thereby can burn broken thing effectively so it is uneven to have suppressed to conduct heat.
The broken thing that is deposited in 22 bottoms, combustion chamber is accompanied by the rotation of furnace main body 20 and swingingly stirring on one side, moves slowly towards openend ground, on one side burning.By burning, oxidation on one side such as the combusting component of the resinae in the broken thing etc. or volatilization are risen on gasification ground on one side.The residue thing that remains in 22 bottoms, combustion chamber becomes valuable metal etc. and is attached to state on the glass fibre.Again, the burning of broken thing is along with towards the openend of furnace main body 20 and promoted.
Atmosphere in the combustion chamber 22 with the burning of broken thing in combustion chamber 22 finish, the mode of the value vanishing of hot igloss amount in the residue thing suitably controls.The supply flow rate of the input amount that the Temperature Distribution in the combustion chamber 22 can be by regulating broken thing respectively, the air that air supply port 42 is supplied with, the output of burner 41, the rotating speed of furnace main body 20 are controlled to the best.For example, with the assigned position place between wall portion 23 and openend, the mode that the temperature of broken thing reaches the temperature of regulation (for example 900 ℃) is controlled and is got final product.
During the burning of broken thing is handled, be maintained oxidizing atmosphere in the combustion chamber 22 and be air ratio more than 1.0, thereby actively burn again.If be maintained oxidizing atmosphere like this, then the volatilization of Br is carried out especially effectively, thereby can reduce the amount that residues in the Br in the residue thing effectively.Air ratio is not the same in combustion chamber 22, but different on length direction and radial direction, but in order to carry out the burning of broken thing reliably, and air ratio is preferably does to become than 1 big for example about about 1.5.But, consider in high oxidation atmosphere to the bad influence of furnace main body 20, about air ratio is preferably and is suppressed at for example below 2.0.In addition, in order suitably to control the atmosphere in the combustion chamber 22, broken thing is supplied to combustion chamber 22 interior getting final product quantitatively.If like this,, suitably carry out each control of the supply flow rate of air supply port 42, the output of burner 41, the rotating speed of furnace main body 20 etc. easily with regard to the easy grasp amount of oxygen necessary in order to keep oxidizing atmosphere.
Broken thing burns the back like this combustion chamber 22 in and residual residue thing drops in the furnace main body 51 of after burner 5 from the openend of furnace main body 20, is discharged in the interior cooling water of hydrolock conveying device 10 by residue thing outlet 53.In hydrolock conveying device 10, the residue thing is by being cooled off by the cooling water washing, and again, the harmful substance of Br, Cl, S etc. is removed from the residue thing.In addition, for the harmful substance of Br, Cl, S etc. is removed from the residue thing, thereby considered to carry out for a long time the burning method of oxidation residua thing up hill and dale in combustion chamber 22, but in the present embodiment, because can reduce Br, Cl, S etc., so can make the burning in the combustion chamber 22 easy by hydrolock conveying device 10.Thereby, can realize the reduction of processing cost.
On the other hand, the gas (exhaust) in the combustion chamber 22 after the openend of furnace main body 20 is discharged in the furnace main body 51 of after burner 5,52 internal combustion in the combustion chamber.That is, carry out the burning again (second-time burning) that produces by after burner 5.In combustion chamber 52, exhaust is stirred by the air-flow of supplying with from air supply port 81, thereby forms the swirling eddy that helical form rises.22 interior exhausts of discharging mix on one side and from the air of air supply port 81 supplies and the fuel gas that sprays from burner 82 from the combustion chamber, and helically rising burning on one side is in the upper end of furnace main body 51, from export mouth 71 discharges.By the processing in this combustion chamber 52, the unburned gas burning that includes dioxin, carbon monoxide (CO) etc. in the exhaust.Be that the ， dioxin decomposes.Again, while by making exhaust rotation that it is contacted with fuel gas, burning and gas-exhausting effectively.And then, have and can suppress to refine slag and on furnace main body 51, adhere to this effect.
In the burning, the wind speed that supplies to the air in the combustion chamber 52 from air supply port 81 for example is about more than the 10m/s, is preferably to do to become more than the 30m/s, again, the time (burning time) that exhaust is stranded in the combustion chamber 52 is more than 2 seconds, is preferably more than 4 seconds, for example more than 6 seconds.Again, the ignition temperature of exhaust is preferably 900 ℃ or more more than 800 ℃ at least.With this, burning and gas-exhausting is realized the completing combustion of exhaust, thereby can be decomposed dioxin reliably reliably.In addition, if ignition temperature is too high, then the burden in refrigerating work procedure thereafter becomes big, so ignition temperature is below 1100 ℃, is preferably below 1000 ℃.
The exhaust of discharging from export mouth 71 imports in the cooling chamber 92 by derivation passage 72, gas introduction port 93.Through gas introduction port 93 time, exhaust, again, in cooling chamber 92, is stirred by the vaporific cooling water that sprays from each cooling water supply port 100 towards the mode rectification of the direction of rotation of stipulating to pass through cowling panel 95.With this, in cooling chamber 92, form the swirling eddy that helical form descends.Exhaust mixes with cooling water smoke on one side and cools off helically decline on one side, flow in the export mouth 111, discharges in cooling chamber 92.Be contained in dust deposit in the exhaust in the bottom of cooling tower main body 91.By forming above-mentioned spiral helicine down current, just chilling exhaust reliably.Again, the dust that drops to the bottom of cooling tower main body 91 is suppressed by air-flow, thereby can prevent that dust from raising up.Thereby, can reclaim dust reliably.And then, can prevent that dust or refining slag are attached on the cooling tower main body 91 or the generation corrosion.
The speed of the air-flow in the cooling chamber 92 or temperature can be controlled by the emitted dose of regulating cooling water.Again, the mode that is quenched to the temperature of regulation at short notice with exhaust in cooling chamber 92 is suitably controlled.For example, regulate as follows: from gas introduction port 93 the exhaust that imports under about state more than 900 ℃ export mouth 111 become about below 180 ℃ about.The cooling velocity of exhaust is the synthetic again cooling velocity that does not produce dioxin, gets final product about for example about 500 ℃/s is above.By coolant exhaust so hastily, just can prevent that the composition that decomposes by the burning in combustion chamber 52 is synthetic again.Particularly, below the synthetic again temperature (about about 300 ℃) that is cooled to be easy to generate dioxin hastily, just can prevent synthesizing again of dioxin.Can prevent to remove damage, the degeneration that the heat of the bag type filtering apparatus 7 of processing causes because of the flying dust that carries out exhaust thereafter again.Emitted dose to cooling water is carried out FEEDBACK CONTROL, so that for example based on the temperature measuring value in the exhaust at gas introduction port 93 places, make this temperature measuring value become for example about 180 ℃ of desired value.
The exhaust of deriving from export mouth 111 imports to the bag type filtering apparatus 7 through deriving passage 112.Through during deriving passage 112, supply with active carbon, calcium hydroxide from active carbon feed path 120, calcium hydroxide feed path 121 in exhaust respectively, mix with exhaust.The exhaust that imports in the bag type filtering apparatus 7 flow into the inboard from the outside of bag filter 131.Residue in flying dust in the exhaust, active carbon etc. by catching in the outside of bag filter 131, thereby from exhaust, remove.In the flying dust of catching, include heavy metal by bag filter 131.Again, exhaust further purifies by active carbon.And then, residue in small amounts of inorganic class in the exhaust or carbon monoxide etc. by charcoal absorption, thereby catch by bag filter 131 with active carbon.In deriving passage 112 or on the filter cloth surface of bag filter 131, be contained in HBr, HCl, SO in the exhaust again,
XDeng acid ingredient neutralize by calcium hydroxide.And, because of the salt that calcium hydroxide or neutralization generate is caught by the outside of bag filter 131.In addition, supply to the quantity delivered that derives the calcium hydroxide in the passage 112, based on the acid ingredient amount in the exhaust of prediction be defined as can be fully in and the amount of exhaust get final product.
From bag type filtering apparatus 7, discharge by export mouth 133 by the exhaust that bag filter 131 purifies, and deliver in the chimney through discharging road 135.And, as harmless in fact clean air, and from chimney 8, be discharged in the atmosphere.
On the other hand, the residue thing that is gathered in the described hydrolock conveying device 10 is discharged from hydrolock conveying device 10 by the driving of scraping plate transmission mechanism 62, and is transported in the enveloping field 68.Again, the dust that is piled up in quenching apparatus 6 on the bottom of cooling tower main body 91 is discharged from outlet 115, and is transported in the enveloping field 68.Being piled up in residue thing in the enveloping field 68 etc. is transported to and smelts institute.And the smelting process by existing gold or copper etc. reclaims and utilizes valuable metal class in the residue thing.
Again, the flying dust of being caught by the outside of bag filter 131 in bag type filtering apparatus 7 etc. drops to the bottom of housing 130, discharges from outlet 141.And, be stored in the flying dust storagetank 150 after, supply in the evenly mixing device 151, add heavy metal immobilization material or water etc., carry out the damping of flying dust, fixing, the stabilisation of heavy metal., finally be transported to handle place, imbed processing thereafter.
According to such castoff processing system 1, by the rotary furnace device 4 broken thing that burns, just can make the combusting component gasification of resin in the broken thing etc. efficiently, thereby can obtain including the residue thing of valuable metal at short notice with this.Again, because can not make the cooling ground, combustion chamber 22 of rotary furnace device 4 supply with broken thing, thus do not need to carry out the adjusting of the cooling of combustion chamber 22 or intensification etc., thus can will be maintained high temperature in the combustion chamber 22, be efficiently therefore.Again,, burn while stirs by rotary furnace device 4 because under the state of the useless printed base plate of fragmentation, thus the broken thing that can not burn with omitting, thus combusting component is gasified.
And then by the exhaust that burning in after burner 5 produces at rotary furnace device 4, the De dioxin is decomposed in the exhaust, by chilling in quenching apparatus 6 thereafter, can prevent the synthetic again of dioxin.Thereby, can prevent that dioxin is discharged in the atmosphere.By the interpolation and the control of dust in bag type filtering apparatus 7 of calcium hydroxide and active carbon, can from exhaust, remove flying dust, HBr, HCl, SO reliably again,
XDeng acid ingredient, dioxin, thereby with exhaust, safety be discharged in the atmosphere.
Again, in rotary furnace device 4, because the output by the rotating speed of regulating furnace main body 20, the supply flow rate that comes from the air of air supply port 42, burner 41 etc. just can be controlled the interior atmosphere in combustion chamber 22, so can wait corresponding to the size of the kind of broken thing, composition, particle and at random regulate fired state, thereby suitably burning.In after burner 5, just can control atmosphere in the combustion chamber 52 because come from the output of the supply flow rate of air of air supply port 81 or burner 82 by adjusting, so can at random regulate fired state, thereby burning and gas-exhausting reliably corresponding to the state of exhaust.Because just can control atmosphere in the cooling chamber 92, so can be with the mode of synthesizing again that do not produce dioxin coolant exhaust reliably by the emitted dose of in quenching apparatus 6, regulating the cooling water come from cooling water supply port 100.
More than, preferred implementation of the present invention has been described, but the present invention is not limited to such example.Those skilled in the art certainly expect various modifications or revise example that they also belong in the technical scope of the present invention certainly in the category of the described technological thought of scope of claim.
As shown in Figure 8, can on the furnace main body 20 of rotary furnace device 4, have the thermometer 160 of the temperature of positions different in a plurality of mensuration combustion chamber 22.Thermometer disposes at certain intervals along the length direction of furnace main body 20, and under this situation, the interval of thermometer 160 for example is about about 1～3m, is preferably about about 2m.At a plurality of positions configuration thermometers 160, just can grasp the interior Temperature Distribution in combustion chamber 22 or the variations in temperature of broken thing by like this based on the measured value of each thermometer 160.Promptly, by carrying out the adjusting of the supply flow rate of air supply port 42, the output of burner 41, the rotating speed of furnace main body 20 etc. based on the Temperature Distribution in the combustion chamber 22 or the programming rate of broken thing, just can more suitably control the atmosphere and the temperature of broken thing in the combustion chamber 22, thus the raising fired state.
In addition, in thermometer 160, be built in the temperature detector 160a in the wall portion of furnace main body 20, as shown in Figure 9, be preferably and use the stable on heating material that has of glass fibre etc. to protect.In example as shown in Figure 9, the outer peripheral face of roughly bar-shaped temperature detector 160a is by covering by forming the guard member 161 that glass fibre roughly cylindraceous constitutes, and then the outer peripheral face of guard member 161 covers by shell 162 cylindraceous roughly.On furnace main body 20, be formed with the furnace shell 20a of the shell that connect to constitute furnace main body 20 and the through hole 163 of the refractory body 20b that is provided with along the inner surface of furnace shell 20a again.Shell 162 is fixed to insert the mode of leading in through hole 163.In the outside of furnace main body 20, have flange 164 in the end of shell 162 again.Temperature detector 160a is fixed on this flange 164, and is fixing with respect to shell 162, furnace main body 20 by flange 164.And temperature detector 160a disposes in such a way: insert and lead in guard member 161, and more side-prominent than the refractory body 20b of furnace main body 20 to combustion chamber 22, thus can be with the temperature in the outstanding leading section mensuration combustion chamber 22.In addition, if cover the front end of the temperature detector 160a of combustion chamber 22 sides, then more can protect temperature detector 160a reliably by adhesive for example etc.
Can have the inclined angle regulating mechanism at the angle of inclination of the furnace main body 20 of regulating rotary furnace device 4, thereby make the angle of inclination variable again.If like this, just can be controlled at from the translational speed of the broken thing of wall portion 23 sides on the direction of openend, again, can control the interior Temperature Distribution in combustion chamber 22 or the balance of heat etc.Particularly because can not change the translational speed that broken thing is regulated on the rotating speed ground of furnace main body 20, so the stirring capacity that the rotation because of furnace main body 20 is produced reduce, thereby keep the uniformity of the fired state of broken thing well.For example, can regulate translational speed of broken thing etc. corresponding to the flowability of broken thing.
Bevel angle adjustment mechanism 170 for example as shown in Figure 8, is done to become and is had the supporting pallet 171 that can regulate the angle of inclination, the 171a of edge portion elevating mechanism 172 these structures up and down that make supporting pallet 171.In Fig. 8, drive division 21, supporting roller 27, furnace main body 20 etc. are arranged on the supporting pallet 171.Supporting pallet 171 can be that fulcrum tilts with the central shaft 173 that is equipped with along the 171b of the edge portion side of after burner 5 sides, can pass through the driving of elevating mechanism 172 and lifting with the 171a of the edge portion side of the opposed wall of 171b portion of edge portion 23 sides.Elevating mechanism 172 is provided to the below of supporting pallet 171, makes axle 174 liftings on the lower surface that is connected in the 171a of the edge portion side that supports pallet 171.As elevating mechanism 172, can use for example hydraulic jack etc.If drive such elevating mechanism 172, the 171a of the edge portion side that then supports pallet 171 moves up and down by axle 174, thereby the angle of inclination of furnace main body 20 changes integratedly with supporting pallet 171.With this, at random regulate the angle of inclination of combustion chamber 22.In addition, the variable range at the angle of inclination of furnace main body 20 can be with respect to generally horizontal plane and towards between for example about about 0.1 °～5 ° of the top.The angle of inclination of furnace main body 20 is for example waited to regulate based on the temperature of Temperature Distribution in the combustion chamber 22 of grasping from the measured value of a plurality of thermometers 160 or broken thing and also can.For example, late the time,, the angle of inclination of furnace main body 20 is slowed down, reduce the translational speed of broken thing, then can increase burning time if descend axle 174 the carrying out of the intensification of broken thing or burning, thus burning fully.On the contrary, the intensification of broken thing or burning carry out if elevating shaft 174 makes the angle of inclination of furnace main body 20 become big, then can increase the translational speed of broken thing, thereby shorten burning time when very fast.Under the lower situation of the temperature of combustion chamber 22 inner wall parts, 23 sides,, the temperature of wall portion 23 sides is heated up, thereby can improve Temperature Distribution if make the angle of inclination of furnace main body 20 more slow again.In addition, in the burning of the broken thing in rotary furnace device 4, even the angle of inclination of furnace main body 20 only changes 1 °, the combustion zone in the furnace main body 20 also changes, thereby the combustion position of burning time, Temperature Distribution etc. is brought bigger influence.Therefore, as long as adjust the angle of inclination of furnace main body 20 a little, just can control combustion position.
For example as shown in figure 10, have under the state of the adjustment at the angle of inclination that stops furnace main body 20 the fixing of fixed bearing pallet 170 and also can with mechanism 182 again.If like this, just can be at more stable status lower support furnace main body 20 or supporting pallet 170, thus the security raising.Again, be scattered in the fixing mechanism 182 that uses, just can alleviate the load that is applied on the elevating mechanism 172, thereby can prevent the fault of elevating mechanism 172 by the load that makes furnace main body 20 or supporting pallet 170.
Bevel angle adjustment mechanism 180 as shown in figure 10, with above-mentioned bevel angle adjustment mechanism 170 similarly, be following structure: have the supporting pallet 171 of supporting furnace main body 20, with respect to the elevating mechanism 172 of ground 181 liftings supportings pallet 171, can support the central shaft 173 of pallet 171 rotatably, the 171b of the edge portion side of supporting pallet 171 is the center rotation with central shaft 173, the edge 171a of portion side rises or descends simultaneously, adjusts the angle of inclination of supporting pallet 171 and furnace main body 20 with this; The position that elevating mechanism 172 but is installed is different with bevel angle adjustment mechanism 170.And then, in embodiment as shown in figure 10, have the fixing of a plurality of fixed bearing pallets 171 with mechanism 182.
In such bevel angle adjustment mechanism 180, axle 174 the upper end of elevating mechanism 172, be arranged at rubber-tyred roller 26 on wall portion 23 sides and supporting roller 27 below, be installed on the lower surface of supporting pallet 171.Again, as shown in figure 11, supporting roller 27,27 is arranged at the both sides, bottom of rubber-tyred roller 26 respectively in the mode that clips furnace main body 20, and elevating mechanism 172 is arranged at the below of each supporting roller 27,27 respectively accordingly.That is, install being applied with the mode of lifting from the below at the position of load with respect to supporting pallet 171 and concentrated area from supporting roller 27.If like this, just can balance support bearing support platform 171 well, thereby also can carry out the adjustment at angle of inclination unchangeably.
Fixing with mechanism 182 respectively near the 171a of edge portion that supports pallet 171, elevating mechanism 172 near, drive division 21 below respectively be provided with a plurality of.Each fixing mechanism 182 that uses can be for example by formations such as bolts and nuts.In example as shown in figure 12, for having the structure that the pin thread groove is formed at 186 and 4 nuts 187 of bolt (stud) on the side of both ends respectively.
One end (bottom) side of bolt 186 below supporting pallet 171, keeps by the base station 185 that is fixed on the ground 181.That is, be provided with in the mode that runs through up and down in the retaining hole 191 that is arranged on the base station 185.Above the retaining hole 191 with below, nut 187 screws respectively with respect to bolt 186., fix with respect to retaining hole 191 from clamping the circumference of retaining hole 191 up and down by these 2 nuts 187 with the bottom side of this bolt 186.
On the other hand, the other end of bolt 186 (upper end) side is connected on the supporting pallet 171.That is, be provided with in the mode that runs through up and down in the retaining hole 192 that is arranged on the supporting pallet 171.Above the retaining hole 192 with below, nut 187 screws respectively with respect to bolt 186., fix with respect to retaining hole 192 from clamping the circumference of retaining hole 191 up and down by these 2 nuts 187 with the bottom side of this bolt 186.
In such structure, fixing at each when the angle of inclination of fixed bearing pallet 171 with in the mechanism 182, clamp nut 187, with respect to base station 185 and supporting pallet 171 and respectively the both ends of set bolt 186 get final product.With this, just can fixingly keep supporting pallet 171 by a plurality of with mechanism 182.On the other hand, when changing the angle of inclination of supporting pallet 171, fixing with in the mechanism 181 at each, change nut 187 is with respect to the position of bolt 186, nut 187 is isolated from retaining hole 191 or retaining hole 192, remove bolt 186 and get final product with respect to the fixing of supporting pallet 171 or base station 185.Promptly, removing each bolt 186 with respect to after supporting pallet 171 or base station 185 fixing, adjust the angle of inclination of supporting pallet 171 by the action of elevating mechanism 172, after the adjustment at angle of inclination is finished, fix each bolt 186 with respect to supporting pallet 171 or base station 185 once more, get final product at the angle of inclination of fixed bearing pallet 171 once more with this.
For example make under the big situation of angle of inclination change lifting supporting pallet 171, in supporting pallet 171 sides, make nut 187 rotations of the top that is arranged at each retaining hole 192, rise respectively along each bolt 186, isolation gets final product thereby distinguish upward from each retaining hole 192.With this, just removed upper end side fixing of each bolt 186, thereby each retaining hole 192 can move up and down along bolt 186, and can adjust the angle of inclination of supporting pallet 171 by the action of elevating mechanism 172.In addition, also very little because the angle of inclination of supporting pallet 171 is very little with respect to the size of the position deviation bolt on the transverse direction 186, retaining hole 192, hindered by bolt 186 so needn't worry moving of retaining hole 192.Thereby, can successfully carry out the adjustment at angle of inclination.Under the fixing state of the upper end side of removing each bolt 186 so respectively, action by elevating mechanism 172 comes lifting shaft 174, after the angle of inclination of supporting pallet 171 becomes desired angle, stop the action of elevating mechanism 172, under the state that keeps by axle 174, make supporting pallet 171 static.And, regulate the position of each nut 187 of supporting pallet 171 sides once more, the upper end side of fixing each bolt 186 respectively once more with respect to supporting pallet 171, thus fixed bearing pallet 171 gets final product.That is, the nut 187 of the below that is positioned at retaining hole 192 is risen, get final product from clamping retaining hole 192 up and down by 2 nuts 187.
According to above formation, just can carry out to change the switching between the state of the state at angle of inclination of furnace main body 20 and supporting pallet 171 and constant tilt angle simply by the position of adjusting nut 187.Again, because can be fixing with the locational supporting pallet 171 of mechanism 182 and the height between the base station 185 corresponding to each is installed, change the position of each nut 187 freely, so, also can support pallet 171 reliably even change the angle of inclination of supporting pallet 171.
In addition, fixing below, the drive division 21 that for example corresponds respectively to each supporting roller 27,27 with mechanism 182 waits to be provided with and also can.That is, install and also can being applied with the mode of lifting from the below at the position of load with respect to supporting pallet 171 and concentrated area from supporting roller 27 or drive division 21 etc.If like this, just can balance support bearing support platform 171 well.
