Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facility for treating and recycling industrial waste, which renders industrial waste containing harmful substances harmless and also regenerates them into useful substances.

[0002]

2. Description of the Related Art Recently, Toshima (Kagawa Prefecture) in the Seto Inland Sea has been regarded as a particularly serious problem, particularly for industrial waste. Here, 40 m of industrial waste containing harmful substances having extremely bad effects on living things such as PCB, dioxin, chlorofluorocarbon, mercury, lead, hexavalent chromium, arsenic, and cadmium are piled up. Under these circumstances,
Hazardous substances penetrate into the ground with rainwater, sediment below industrial waste becomes sludge containing toxic substances, and groundwater is contaminated with toxic substances. Furthermore, not only does poisoned water accumulate on the ground,
The water spills into the surrounding ocean, polluting beaches and oceans.

Many methods have been proposed for detoxifying industrial waste. However, all of these methods specialize in the treatment of specific industrial waste, and as in the case of Teshima in the Seto Inland Sea, they have been used as toxic substances. There is no one that can collectively treat a large amount of miscellaneous and highly toxic industrial waste including polluted earth and sand.

[0004]

The industrial waste dumped on Teshima in the Seto Inland Sea is extremely special in the following points, and is extremely difficult to treat because of its specialty. It is.

[0005] Industrial waste is highly toxic. There are many types of industrial waste and many types of poisons. The amount of industrial waste is large. Because a large amount of sediment below the industrial waste is also contaminated with poisons, it is necessary to treat not only a large amount of industrial waste but also a large amount of sediment contaminated with the poison below.
The elapsed time since the industrial waste has been neglected is long, and it is not in a state where the industrial waste can be separated.

Due to such specialty, a large amount of miscellaneous and highly toxic industrial waste including sediment contaminated with poison is collected from industrial waste dumped on Teshima in the Seto Inland Sea. What can be processed is required.

[0007] The present invention has been made in view of the above circumstances, and a variety of miscellaneous and highly toxic large quantities including earth and sand contaminated with toxic substances, such as industrial waste dumped on Teshima in the Seto Inland Sea. It is also an object of the present invention to provide an industrial waste treatment / recycling facility capable of collectively detoxifying industrial waste without separating it and separating the industrial waste into useful materials without waste. .

[0008]

SUMMARY OF THE INVENTION An industrial waste treatment and regeneration facility according to the present invention passes industrial waste containing toxic substances through a horizontal tubular body, and from the outside of the tubular body, passes the tubular body into the industrial waste. Indirect heating to a low temperature lower than the temperature at which organic matter is gasified, low-temperature heating furnace that detoxifies toxic gas generated from industrial waste due to the low-temperature heating, and low-temperature industrial waste that has passed through the low-temperature heating furnace It is passed through a horizontal tubular body provided continuously to the tubular body of the heating furnace, and indirectly heats the tubular body from the outside of the tubular body to a high temperature higher than the temperature at which organic matter in industrial waste is gasified. A first recovery furnace that collects organic gas generated from organic matter in the industrial waste and separates and collects non-metals such as earth and sand in the industrial waste, and an industrial waste that has passed through the first recovery furnace Above the melting temperature of metals in industrial waste. Heated, and a second recovery furnace for recovering the melt.

The most significant feature of this processing and regeneration equipment is that the low-temperature heating furnace, the first recovery furnace, and the second recovery furnace are combined in tandem. In the low temperature heating furnace, the inside of the tube is indirectly heated from the outside of the tube to a low temperature lower than a temperature at which organic matter in industrial waste is gasified. As a result, poisons having a relatively low boiling point, such as chlorofluorocarbon and arsenic, are vaporized together with the moisture and air in the industrial waste. The remaining industrial waste has low toxicity and becomes dried organic matter and inorganic matter. Inorganic substances are classified into metals and nonmetals such as earth and sand and ceramics.

In the first recovery furnace following the low-temperature heating furnace, the inside of the pipe is indirectly heated from the outside of the pipe to a temperature higher than the temperature at which organic matter in industrial waste is gasified. Thereby, the organic matter in the industrial waste is gasified, and an organic gas having a high concentration can be obtained. If low-temperature heat treatment is not performed in advance, moisture, air, and the like are generated here, and a high-concentration organic gas cannot be obtained.
Here, it is meaningful to provide a low-temperature heating furnace. This high-concentration organic gas can be used as a fuel directly or as an oil.

In the first recovery furnace, toxic gases having a high boiling point such as dioxin may be generated. Therefore, it is desirable that this furnace is also provided with means for detoxifying toxic gas generated from industrial waste.

The gasification of organic matter in industrial waste leaves mainly inorganic matter. As described above, the inorganic substances are classified into metals and nonmetals such as earth and sand and ceramics. If the industrial waste contains a large amount of non-metal such as earth and sand, ceramics, etc., if the industrial waste is sent directly to the next second recovery furnace, the burden on the furnace becomes extremely large, and the treatment efficiency decreases and the furnace cost decreases. Invite soaring. Therefore, in the first recovery furnace, nonmetals such as earth and sand are separated and recovered from the remaining inorganic substances. At this stage, since the toxicity has almost disappeared, the recovered nonmetal can be used as earth and sand for cultivation, cultivated soil, molding material and the like.

As means for separating non-metals such as earth and sand in industrial waste, a sieve-shaped opening is provided on the side surface of a tubular body, and an industrial vessel which travels in the tubular body while rotating by a spiral blade type propulsion carrier. It is preferable that the waste is sieved through the opening.

In the low temperature heating furnace and the first recovery furnace, the pipe is heated indirectly and the industrial waste in the pipe is not burned.
There is no secondary generation of toxic combustion gases. As the indirect heating means here, a gas burner or an oil burner is preferable. This is because the gas collected in the first recovery furnace and the oil obtained from the gas can be used as these fuels.

In the second recovery furnace following the first recovery furnace, the remaining metal or ceramic is melted and recovered by direct heating. These metals and ceramics are also harmless.

By the above process, a large amount of various and highly toxic industrial wastes including sediment contaminated with toxic substances, such as industrial wastes dumped on Teshima in the Seto Inland Sea, can be separated without separation. Detoxification treatment is carried out in a lump, and the industrial waste is recycled into useful materials without waste.

As the direct heating means in the metal recovery furnace, a multi-arc is preferable. Multi-arc is also suitable as a means for detoxifying toxic gas generated from industrial waste.

The multi-arc is a plasma arc developed by the present applicant. Normally, a plurality of carbon electrode rods are arranged symmetrically and inclined around the center line so that the tips thereof abut at a predetermined interval, and a voltage having a different phase is applied to the electrode to thereby form the multi-electrode rod. An arc occurs.
Since the features of the multi-arc have already been described in many patent applications and the like, many will not be described, but important ones are listed as follows.

The multi-arc stably generates a high-temperature arc plasma flame of 4000 ° C. or more without a counter electrode. Generation starts instantaneously in the air, in a vacuum, in water, and in an inert gas. The flame is strongly reducing and does not oxidize metals without the use of inert gases. No noise and no interference. Since the multi-arc plasma flame is thermal energy due to electron vibration, it is accompanied by intense electromagnetic vibration and a rotating magnetic field. In addition to high temperatures, it also has strong ultraviolet and other wave energy.

If a multi-arc is used as the direct heating means in the second recovery furnace, not only metals but also non-metals such as earth and sand, ceramics, etc. are melted and converted into useful materials. Further, the toxic gas not separated in the first recovery furnace is also rendered harmless. When a multi-arc is used as a means for detoxifying toxic gas generated from industrial waste, harmful substances such as PCB, dioxin, and chlorofluorocarbon which are difficult to decompose are surely detoxified.

The workpiece 40 that has passed through the low-temperature heating furnace 100
0 is conveyed in the pipe 210 of the first recovery furnace 200 from upstream to downstream. The inside of the tube 210 is indirectly heated by the burner 230 to a temperature higher than the temperature at which the organic matter is gasified. For this reason, the workpiece 40 transported in the pipe 210
0 is heated to a high temperature with the supply of air shut off. Specifically, about 450 ° C. in the middle of the tube 210,
It is heated to about 700 ° C. at the downstream end. Thus, the organic matter in the processing object 400 is gasified to generate an organic gas. This gas has a high concentration because moisture, air, and the like have been removed in advance by the low-temperature heating furnace 100. Further, poisons having a relatively high boiling point such as dioxin are vaporized.

The organic gas generated in the pipe 210 accumulates in the tank 241 of the gas recovery device 240, and is turned into oil by the oiling device 242, and then the oil fine particles are dispersed in water by the emulsifying device 243. Emulsion. Since the gas collected in the tank 241 has a high concentration, when the burners 130 and 230 are gas burners, they can be used as fuel. When the burners 130 and 230 are oil burners, the emulsion obtained by the emulsifier 243 can be used as the fuel.

The toxic gas generated in the pipe 21 is supplied to the gas detoxifying device 250 by the heat-resistant and breathable ceramics 252 and 253.
Decomposes into other harmless substances. Alternatively, it is synthesized with another substance to change into another harmless substance. Further, it is decomposed and synthesized into harmless substances by the multi-arc generated from the multi-arc generating electrode 254.

It is released to the atmosphere through 57. The fine particles accumulated in the filter 257 are appropriately removed from the outlet. The heat recovered by the heat recovery device 255 is used for power generation and the like. The electricity is used to generate a multi-arc. In addition, the propagation of microorganisms and the like are performed in the bio tank 259 using the residual heat of the conduit 251.

An object 400 to be processed conveyed in the tube 210
Is rotated by a spiral blade type propulsion carrier 220.
As a result, the workpiece 400 is classified by the sieve-shaped openings 211 and 211 on both sides of the tube 210. That is, non-metal, mainly fine earth and sand in the object 400 is
From the pipes 1 and 211, they are discharged out of the pipe 210 and flow into the lower hoppers 280 and 290. Upstream hopper 28
The earth and sand that flows into 0 contains some organic matter,
It is sequentially extracted from the lower outlet 281 and used as cultivated soil. The earth and sand flowing into the hopper 290 on the downstream side does not contain an organic component, so that the lower outlet 2
It is sequentially extracted from 91 and used as earth and sand for forming, a molding material and the like.

In the tube 210, metals (lead and aluminum) having a low melting point are melted. Among them, a melt of lead is collected in the crucible 260, and a melt of aluminum is collected in the crucible 270.

As described above, when the object 400 passes through the first recovery furnace 200, the organic matter in the object 400 is gasified, removed, and collected. Also, poisons are almost completely removed. Further, the earth and sand in the inorganic substance is removed and collected. Therefore, the processed object 400 after passing through the gas / non-metal sampling furnace 200 is only an inorganic substance other than earth and sand and a small ceramic, that is, a metal and a relatively large ceramic. Then, these are introduced into the second recovery furnace 300 following the first recovery furnace 200.

The second recovery furnace 300 includes an inclined pipe 310 following the pipe 210 of the first recovery furnace 200, and a crucible 320 connected to the downstream end of the pipe 310. The tube 310 is a heat-resistant tube. A multi-arc generating mechanism 330 is provided at a plurality of locations in the longitudinal direction of the tube 310. Due to this multi-arc, the inside of the tube 310 is directly heated up to about 1600 ° C. in order at the downstream end.

The object 400 to be processed, which has exited the first recovery furnace 200,
That is, the metal and the relatively large ceramic are collected in the second recovery furnace 3.
The tube is conveyed by gravity through the tube 310 of No. 00, and is directly heated by a multi-arc in this process. That is, the object 400 is directly heated for the first time. This direct heating causes the metal to melt. The ceramic also melts.
Furthermore, if any poison remains, it is also rendered harmless.
In order to apply a propulsive force to the workpiece 400, it is preferable that the multi-arc be ejected while being inclined forward.

The melt of the metal and the ceramic is crucible 320
Where it is separated by specific gravity. That is, tungsten or the like having a large specific gravity accumulates at the bottom, and copper, gold, irons, and ceramics and the like accumulate thereon in this order. By extracting them from the crucible 320 without mixing them, metals and ceramics are recovered by type.

In the second recovery furnace 300, the workpiece 400
As a means for directly heating the gas, a gas burner or an oil burner may be used. Particularly desirable is a configuration in which these burners are arranged in an upstream portion and an intermediate portion, and a multi-arc is irradiated in a downstream portion. By inclining the flame forward from the burners attached to the upstream portion and the intermediate portion of the pipe 310 into the pipe 310, it is possible to give a larger propulsive force to the workpiece 400. In addition, by using a brown gas or an emulsion as a fuel for these burners, the inside of the tube 310 and the object 400 to be treated therein are heated to a high temperature exceeding 1000 ° C., and the remaining toxic substances are also decomposed. Brown gas is a mixed gas of hydrogen and oxygen generated when water is decomposed when a multi-arc is generated in water, and is a combustible gas having extremely high combustion calories. By irradiating the multi-arc in the final stage, not only the metal in the workpiece 400 but also the ceramic is melted, and finally the remaining poison is decomposed.

As described above, by using the industrial waste treatment and regeneration equipment in which the low temperature heating furnace 100, the first recovery furnace 200, and the second recovery furnace 300 are combined in tandem, the industrial waste is completely rendered harmless. It is recovered and used as a useful substance without waste.

The low-temperature heating furnace 100, the first recovery furnace 200, and the second recovery furnace 300 are connected in tandem. A plurality of connected bodies of the first recovery furnace 200 and the second recovery furnace 300 are arranged in parallel. With a configuration in which the furnace is connected to one low-temperature heating furnace 100, the processing speed can be balanced between the furnaces, and the processing efficiency can be increased. As means for transporting the workpiece 400 within the pipes 110 and 210, a means other than the screw blade type propulsion transporters 120 and 220 can be used.
