Various types of industrial waste including containers containing industrial waste, containers containing flame-retardant industrial waste, containers containing solid industrial waste, and containers containing liquid industrial waste Containers are carried into the processing equipment by trucks or the like. Conventionally, industrial waste carried into a treatment facility is thrown into a storage tank regardless of its type, and then put into an incinerator from the storage tank for incineration.

[0004] However, for example, when acidic industrial waste and alkaline industrial waste are put into the same storage tank,
Due to the chemical reaction between industrial wastes, there is a danger of heat generation, generation of harmful gases, explosion, and the like. For example, flammable industrial waste can be used as fuel during incineration, but if flammable industrial waste and flame-retardant industrial waste are put into the same storage tank, both will be mixed, Combustible industrial waste cannot be used effectively as such a fuel.

Accordingly, an object of the present invention is to provide a processing facility and a processing method for preventing a chemical reaction between industrial wastes and effectively utilizing flammable industrial wastes as fuel for incineration. It is in.

Alternatively, the type of industrial waste may be selected according to one criterion so as to separate solid industrial waste and liquid industrial waste. In addition, industrial waste is classified according to two or more criteria, for example, to separate alkaline and combustible industrial waste, alkaline and flame-retardant industrial waste, and acidic industrial waste. The type may be selected.
When sorting into acidic industrial waste and alkaline industrial waste, neutral industrial waste may be sorted into either acidic industrial waste or alkaline industrial waste. In the case of sorting between solid industrial waste and liquid industrial waste, for example, a viscous substance or a slurry substance can be sorted into either solid industrial waste or liquid industrial waste.

After the sorting, the container is transported to a plurality of storage tanks according to the type of industrial waste by the transport means, the container is opened by the opening means, and the industrial waste in the container is put into the storage tank. . Then, the industrial waste stored in each storage tank is put into an incinerator by an input device for each type, thereby incinerating the industrial waste.

Therefore, according to the first aspect of the present invention, by storing the industrial waste in the storage tank separately for each type, for example, the chemical reaction between acidic industrial waste and alkaline industrial waste can be achieved. Can be prevented, and dangers such as heat generation, generation of harmful gas, and explosion can be avoided. Also, for example, by injecting flammable industrial waste into an incinerator separately, it can be used as fuel for incineration.

By doing so, the odor and harmful gas of industrial waste generated from the storage tank and the container after opening can be confined in the enclosed space, so that environmental pollution can be prevented, and the workers are outside the enclosed space. This makes it possible to avoid contact with the atmosphere such as the odor of industrial waste and harmful gas. In this case, for example, the inside of the sealed space may be exhausted by an appropriate exhaust mechanism such as an exhaust fan. Then, the odor and harmful gas of the industrial waste generated in the enclosed space can be efficiently exhausted without leaking to the outside, and the working environment can be further improved.

Further, as described in claim 3, an exhaust means may be provided in the sorting section. Then, when the sorter sorts the type of industrial waste in the container, it becomes possible to exhaust the odor and harmful gas leaked from the container by the exhaust means. Workers can be prevented from coming into contact with the atmosphere such as the odor of industrial waste or harmful gas.

According to a fourth aspect of the present invention, there is provided a method for treating industrial waste by charging it into an incinerator, wherein the waste is one of acidic and alkaline, flammable and flame retardant, solid and liquid.

As described above, when the operator 30 sorts the industrial waste, by opening a hole in the upper surface of the drum D, there is a fear that the smell of the industrial waste and harmful gas leak from the inside of the drum D. is there. However, in this embodiment, as described above with reference to FIG. 3, since the odor and harmful gas leaked from the inside of the drum D in the sorting unit 14 are removed through the exhaust duct 32, such a concern is avoided. Thus, it is possible to prevent the operator 30 from coming into contact with the atmosphere such as the odor of industrial waste and harmful gas.

The drums D, which have been sorted out in this manner, are transferred to the loading side 40 of the alignment conveyor 13 via the transfer conveyor 12 and conveyed, and are aligned by the alignment device 42 for each type of contents. , Alignment conveyor 13
Is carried out to the carry-out side 41. Here, the operation of the sorting device 42 will be described in detail. For example, as shown in FIG. 17, the drum D containing the type c industrial waste and the type a industrial waste enter the loading side 40 of the sorting conveyor 13. For example, if the drum D and the drum D containing the industrial waste of the type c are placed in order, the first drum D
When the (type c) is loaded into the aligning device 42, the stock unit 48c is positioned between the loading side 40 and the unloading side 41 of the sorting conveyor 13 in advance. And alignment conveyor 1
Then, the first drum D is carried into the stocking section 48c of the aligning device 42 from the carrying side 40 of the third drum D.

After the first drum D is carried into the stock section 48c in this way, the first drum D is temporarily stopped on the stock section 48c. Next, as shown in FIG. 18, the stock portion 48a is moved to the loading side 40 of the alignment conveyor 13.
And the discharge side 41. Next, the second drum D (type a) is carried into the stock unit 48a of the sorting device 42 from the loading side 40 of the sorting conveyor 13.

After the second drum D is transported from the loading side 40 of the aligning conveyor 13 to the stock section 48a of the aligning device 42, the second drum D is loaded into the stock section 4.
Pause on 8a. Next, as shown in FIG.
The stock unit 48c is located between the carry-in side 40 and the carry-out side 41 of the alignment conveyor 13. Next, the first drum D (type c), which has been stopped in the stock unit 48c, is unloaded to the unloading side 41 of the alignment conveyor 13, and the third drum D (type c) is unloaded.
From the loading side 40 of the aligning device 42, and the third drum D transported from the loading side 40 to the stock unit 48c. 41. As a result, the same type c
It is possible to carry out the drums D containing the industrial waste in a line by two.

The drums D that have been aligned two by two by the alignment device 42 in this manner are transported to the end of the unloading side 41 of the alignment conveyor 13. On the other hand, the supply plate 5
6 moves while being suspended by the rail 55, and stops at the side of the terminal end of the unloading side 41 of the alignment conveyor 13. Thereafter, the operation of the pusher 60 causes the two drums D to be transferred to the supply plate 56 from the end of the unloading side 41 of the alignment conveyor 13.

Next, the supply plate 56 moves again, and if the contents of the drum D are industrial waste of type a, the drum D is transported to the vicinity of the opening charging device 51a, and the drum D
If the contents are industrial waste of type b, the opening input device 51
b, the drum D is transported to the vicinity of the opening input device 51c if the contents of the drum D are industrial waste of the type c, and the contents of the drum D are industrial waste of the type d. For example, the drum D is transported to the vicinity of the opening charging device 51d.

That is, for example, the case where the contents of the drum D are the industrial waste of the type a will be described. The supply plate 56 is previously stored in the storage tank 5 in the opening input device 51a.
0a (a dashed line 86 'in FIG. 9).
(Indicated by (1)), the drum D stops at the side of the cage 86 and is transported to the side of the cage 86. Before the supply plate 56 moves to the side of the cage 86 in this manner, the two empty drums D which have already been loaded in the opening loading device 51a are pushed.
The drums D are not in the cage 86 because the drums D are already transferred from the cage 86 to the carry-out plate 57 by the operation of the cage 10. The unloading plate 57 that has received the empty drum D from the cage 86 is moving from the side of the cage 86 toward the start end of the unloading conveyor 156, so that the unloading plate 57 is positioned beside the cage 86.
Does not exist. The cage 86 has the opening 91 directed to the opposite side to the storage tank 50a by the operation of the cylinder device 96 described above with reference to FIG. Also, in the opening cutter 99, the two-stage cylinder device 105 operates in a shortened manner, the cutter body 101 is lifted, and the blade portion 103 is retracted above the cage 86 (the state shown by solid lines 101 and 103 in FIG. 14).

Then, the supply plate 5 is provided beside the cage 86.
When 6 stops, the two drums D are transferred from the supply plate 56 into the cage 86 by the operation of the pusher 61a.

When the two drums D are housed in the cage 86 in this way, the frame 80 moves forward on the rails 82 by operating a drive mechanism (not shown) in the opening opening device 51a, and the cage 86 is stored. Tank 50a
It moves to the upper position (the position indicated by the solid line 86 in FIG. 9).

Next, in the opening cutter 99, the two-stage cylinder device 105 is operated to extend and operate the cutter body 101.
Is lowered to open the end face of the drum D. That is, when the two drums D housed in the cage 86 move to the position on the storage tank 50a, first, the cutter body 101 is lowered through the hole 93 on the upper surface of the cage 86, so that one of the drums D is moved. The apex of the blade portion 103 abuts substantially at the center of the end surface (upper end surface), and a small hole is formed. When the cutter body 101 further descends, one end surface of the drum can D is centered on the hole. Is gradually cut along the ridgeline of the blade portion 103, and one end face of the drum D is cut along five lines extending radially from substantially the center. At this time, as shown in FIG. 20, the cut pieces are sequentially bent inside the drum D, so that the cut pieces do not fall into the drum D. In this way, when the blade portion 103 enters the upper part of the inside of the drum D (in FIG.
1 ', 103'), the lowering of the cutter body 101 is stopped, and the cutter body 101 is raised by the shortening operation of the two-stage cylinder device 105, so that the blade 1
03 is retracted above the cage 86 (the state shown by solid lines 101 and 103 in FIG. 14). Thus,
As shown in FIG. 21, a pentagonal hole D ′ is formed on one end surface of each of the two drums D housed in the cage 86.

The two drums D stored in 6 are turned over. When the drum 86 is overturned by rotating the cage 86 in this way, the cage 86 is rotated in such a direction that the opening 91 of the cage 86 does not face downward so as not to drop the drum D from inside the cage 86. . As a result, 5
One end face of the drum D having the square hole D ′ is turned down, and the other end face of the drum D that has not been drilled is turned up.

Next, the two-stage cylinder device 105 is extended again, and the cutter body 101 is lowered through the hole 93 on the upper surface of the cage 86. A rectangular hole D 'is formed. After the hole D 'is formed in the other end surface of the drum D, the two-stage cylinder device 105 is further operated to extend, and the cutter body 1 is moved.
By continuing the downward movement of 01, the cutter body 101 enters the inside of the drum D through the hole D 'formed in the other end surface of the drum D. As a result, the contents filled in the drum D are removed from the cutter body 10.
1, the contents fall through the hole D 'on one end face of the drum D formed previously and the hole 93 on the lower surface of the cage 86, and are placed in the drum D. The industrial waste a is put into the storage tank 50a. Then, the cutter body 101 penetrates through the inside of the drum can D and descends to a position where the blade portion 103 protrudes below the drum can D (a position indicated by dashed lines 101 ″ and 103 ″ in FIG. Almost all of the industrial waste was forcibly depressed and the storage tank 50

Also in this case, the cage 86 is rotated so that the opening 91 of the cage 86 does not face downward, so that the drum D is not dropped from inside the cage 86. In addition, the opening input device 51
By operating a drive mechanism (not shown) at a,
The frame 80 moves backward on the rail 82 and the cage 86
Moves to the position retreated from above the storage tank 50a (the position indicated by the one-dot chain line 86 'in FIG. 14). Also pusher 1
In 10, the rotation plate 113 and the cylinder device 114 are brought into a substantially horizontal posture by the extension operation of the cylinder device 116, and the pusher 110 is moved forward of the frame 80.
Is projected.

Then, the carry-out plate 57 moves while being suspended from the rail 55, and the carry-out plate 57 stops at the side of the cage 86. Before the carry-out plate 57 moves to the side of the cage 86, the supply plate 56 is retracted from the side of the cage 86.

Then, the carry-out plate 5 is placed beside the cage 86.
7 stops, the cylinder device 114 of the pusher 110 is stopped.
Is extended, the piston rod 109 enters the cage 86 from the hole 92 formed in the side surface 90 of the cage 86, and pushes out the two empty drums D stored in the cage 86, respectively, and pushes the empty drums D to the discharge plate 57. Transfer.

Next, the carry-out plate 57 moves again, and
The unloading plate 57 stops on the side of the unloading conveyor 156. Next, by operating the pusher 160, the two empty drums D are transferred from the unloading plate 57 to the unloading conveyor 156.
Is transferred. In this way, the empty drum D is conveyed to the shredder 155 by the unloading conveyor 156 and cut.

Although the case where the contents of the drum D are the industrial waste of the type a has been described as an example, the two drums D containing the industrial waste of the type b are aligned by following the same procedure. If it is conveyed to the terminal end of the discharge side 41 of the conveyor 13, two drums D
(Type b) is the opening input device 51 via the supply plate 56.
After being supplied to b and opened, the industrial waste put in the two drums D is simultaneously put into the storage tank 51b.
Similarly, if two drums D containing type c industrial waste are transported to the end of the unloading side 41 of the alignment conveyor 13, two drums D (type c)
Is supplied to the opening charging device 51c via the supply plate 56 and is opened, and then the industrial waste put in the two drums D is simultaneously charged into the storage tank 51c. Similarly, two drums D containing industrial waste of type d
Is transported to the end of the unloading side 41 of the alignment conveyor 13, the two drums D (type d) are supplied to the opening input device 51 d via the supply plate 56 and are opened. The industrial waste put in the drum D is simultaneously charged into the storage tank 51d. In any case, the empty drum D after the contents are put into the shredder 1 by the unloading plate 57 and the unloading conveyor 156.
It is conveyed to 55 and cut.

Then, as described above, each of the storage tanks 50a, 50

It is put into the inlet 150 of the furnace 3. That is, the charging device 119 described with reference to FIG. 16 is moved above each of the storage tanks 50a, 50b, 50c, and 50d, and the cylinder devices 136, 137, 138, and 141 are appropriately expanded and contracted to operate the storage tanks 50a and 50b. , 50
c and 50d, the industrial waste is scooped out by the shovel 140. Then, the excavator 140 is moved to a position above the charging port 150 of the incinerator 3 by running the charging device 119. Then, the shovel 140 is turned over, and the industrial waste held by the shovel 140 is supplied to the input port 1.
Drop into 50. The industrial waste thus put into the inlet 150 is then put into the adjacent incinerator 3 by the skip conveyor 151 and incinerated.

According to the processing equipment 1 shown in this embodiment, the industrial waste is mixed with the industrial waste a which is a miscellaneous material, the industrial waste b which is alkali or neutral and flammable, and the industrial waste b which is alkali or neutral. Separation into flammable industrial waste c and acidic industrial waste d and separate storage tanks 50a, 50b, 50 for each type.
Since they are stored in c and 50d, chemical reactions between industrial wastes can be prevented, and dangers such as heat generation, generation of harmful gas, and explosion can be avoided. Since the industrial waste b stored in the storage tank 50b is flammable, it can be used as fuel for incineration. In this case, since the other types of industrial wastes a, c, and d are not mixed in the storage tank 50b, the flammable industrial waste b can be effectively used as fuel. Further, the processing equipment 1 of the embodiment includes the respective storage tanks 50a,
50b, 50c, 50d and the odor and harmful gas of industrial waste generated from the inside of the drum D after opening are sealed 16

Being out of the house can avoid contact with the atmosphere such as the odor of industrial waste or harmful gas. The inside of the sealed space 165 may be exhausted by an appropriate exhaust mechanism such as an exhaust fan. Further, when the sorting unit 14 sorts the industrial waste, odors and harmful gases leaking from the drum D are discharged to the exhaust duct 3.
Since the air can be exhausted through the filter 2, the sorting unit 14 can also prevent the operator such as the operator 30 from coming into contact with the atmosphere such as the odor of industrial waste or harmful gas. In particular, in the processing equipment 1 of this embodiment, since the drums D containing the same type of industrial waste are aligned by the aligning device 42, the drums D are opened and charged. When performing this, batch-type processing becomes possible, and the processing capacity can be improved.

The embodiment of the present invention has been described above.
The present invention is not limited to the embodiment disclosed here. For example, when the industrial waste contained in the drum D is liquid or the like, the industrial waste may be sucked from the drum D by a pump or the like without opening the drum D. In this case, for example, as shown in FIG. 1, a discharge conveyor 160 is connected in the middle of the loading side 40 of the alignment conveyor 13, and the drum D containing the liquid industrial waste is separated by the discharge conveyor 160 into a liquid processing unit. 161.

FIG. 22 is an explanatory view of an example of the liquid processing section 161. In this liquid processing section 161, a suction nozzle 164 connected to a suction pump 163 via a hose 162 is suspended by a wire 166 of a balancer 165. Configuration. The balancer 165 is supported so as to be able to run freely on the ceiling of the liquid processing unit 161, and thereby, the suction nozzle 1
64 can be freely moved in the liquid processing unit 161. In addition, the suction nozzle 164 can be moved up and down with a small force at an arbitrary position in the liquid processing unit 161 due to the expansion and contraction of the wire 166 fed from the balancer 165.

If the industrial waste is a liquid, the drum D is transported to the liquid processing unit 161 by the discharge conveyor 160 and the drum D is provided if the industrial waste is a liquid.
It is possible to absorb industrial waste without opening the door. For this reason, the trouble of opening the drum D can be omitted, and the processing can be facilitated. The sucked industrial waste can be sprayed directly into the incinerator 3 and incinerated.
Further, the empty drum D after absorbing the industrial waste can be transported to, for example, a shredder 155 and cut.

In the present invention, the container is not limited to the drum D, and other containers may contain industrial waste. Although the case where the drums D are aligned and processed two by two by the aligning device 42 has been described, three or more drums D may be aligned by the same aligning device. It is also possible to omit the alignment device and process the drums D one by one. Also, the excavator 140 of the charging device 119 uses the storage tanks 50a, 50b, 50c, 50
By periodically stirring the industrial waste in d, solidification of the industrial waste can also be prevented. In the processing equipment 1 of this embodiment, the industrial waste a of miscellaneous materials, the industrial waste b of alkali or neutral and flammable, the industrial waste c of alkali or neutral and flame-retardant, Although the example in which the waste is sorted and treated as industrial waste d is described above, it is also possible to sort, for example, into solid industrial waste and liquid industrial waste.
