AI Technical Summary

Benefits of technology

The patent text describes a treatment method for objects that have both metal and organic substances as components. The method can effectively and economically treat these objects and reduce the production of dioxins. It can also clean soil and remove organic halides from waste. The method involves heating the object under reduced pressure and introducing it into a hermetic zone. The treatment target object can be a waste automobile or other object that contains metals and organic substances. The method can also vaporize and decompose the organic substances, and remove them from the object. Overall, the method provides a way to effectively and safely treat these objects.

Problems solved by technology

Various useful substances are contained in wastes, but they are not separated from the wastes because of difficulty in separation and the like, and most of wastes are disposed of just as they are by reclamation or combustion.
The useful substances in the wastes are required to be separated and recovered, and recycled as much as possible since there exist an energy problem and a problem of exhausting resources.
These noxious substances is not only a cause of environmental disruption but also one of the main causes of difficulty in recycling wastes.
The types of wastes are, however, complicated and various in recent years, and there are many complex wastes in which a plurality of different materials are integrated, and moreover there are wastes containing noxious substances.
To recycle such complex wastes as resources, it is required to selectively separate and recover useful substances and noxious substances from the wastes in which a plurality of different materials are integrated, but such treatment technology has not established yet.

example 1

[0334]FIG. 1 is a perspective view roughly showing an example of a treatment apparatus, and showing the interior thereof by sectioning a portion thereof.

[0335]This treatment apparatus 100 can treat an object to be treated 150 having resins and metals as its components, and it is composed of a purge chamber 101, a first hermetic chamber 102, a second hermetic chamber 103, and a cooling chamber 104.

[0336]These chambers are partitioned off by doors 105 which are openable and closeable partitions. Namely, the outside of the apparatus and the purge chamber 101 are partitioned off by a door 105a, the purge chamber 101 and the first hermetic chamber 102 are partitioned off by a door 105b, the first hermetic chamber 102 and the second hermetic chamber 103 are partitioned off by a door 105c, the second hermetic chamber 103 and the cooling chamber 104 are partitioned off by a door 105d, and the cooling chamber 104 and the outside of the apparatus are partitioned off by a door 105e.

[0393]FIG. 3 is a diagram roughly showing another example of the treatment apparatus, and showing the interior thereof by sectioning a portion thereof. This treatment apparatus 300 also can treat an object to be treated 350 having resins and metals as its components.

[0394]This treatment apparatus 300 is composed of a purge chamber 301, a hermetic chamber 302, and a cooling chamber 303. The hermetic chamber 302 has both the functions of the first hermetic chamber 102 and the second hermetic chamber 103 in the treatment apparatus 100 illustrated in FIG. 1. Specifically, component resins of the object to be treated 350 are thermally decomposed selectively in the hermetic chamber 302, and then a metal is separated and recovered in the same hermetic chamber 302. Specially when a predetermined metal is isolated by the selective thermal decomposition of resins, it is unnecessary to vaporize component metals of the object to be treated 350.

[0404]FIG. 4 is a diagram schematically showing another example of the treatment apparatus.

[0405]This treatment apparatus 400 includes a first hermetic chamber 401 and a second hermetic chamber 402. The first hermetic chamber 401 includes a temperature regulating means not illustrated and is connected to an exhaust system 403 and an exhaust gas treatment system 404. The second hermetic chamber includes a temperature regulating means not illustrated and is connected to an exhaust system 405 and a recovery chamber 406. A carrier gas introduction system 407 is connected to the first hermetic chamber 401 and the second hermetic chamber 402, and thus the regulation of the oxygen concentration and pressurization in each of the hermetic chambers can be performed. The numeral 408 denotes a carrier gas reservoir. The first hermetic chamber 401 and the exhaust gas treatment system 404 are partitioned off by a hermetic door 404b. When the hermetic door 404b is open, a retort 404c is inserted i...

Abstract

A treatment method includes heating a treatment target object under reduced pressure in a hermetic zone to vaporize a component of the treatment target object, and opening a hermetic door and inserting a tube from a side of a treatment system for the vaporized component adjoining the hermetic zone with the hermetic door therebetween such that the tube shields the hermetic door from the hermetic zone to introduce the component vaporized from the treatment target object to the treatment system side.
