Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention crushes and pulverizes and mixes various kinds of plastics, wood waste, paper waste, and other organic waste such as bulky waste, which are discarded from business establishments, offices, and homes. The present invention relates to a non-polluting waste-recycling plant that heats fluidized, solidifies, and then carbonizes to obtain coal.

[0002]

2. Description of the Related Art Conventionally, most combustible wastes have been incinerated in most municipal incineration plants. However, in incineration plants where combustion temperature is not sufficiently controlled, highly toxic dioxins are generated. Then it is not easy to incinerate it. In this way, the environment surrounding waste has changed in recent years,
From the viewpoint of resource reuse, in June 1995, the Law on the Promotion of Separated Collection and Recycling of Containers and Packaging (Container and Packaging Recycling Law) was enacted and promulgated, and it was previously considered to be a stable type. Waste has also been changed to a managed type and it is becoming impossible to landfill easily, waste plastic is collected separately and it is easy to reuse it, and a wider recycling method of waste containing plastic is studied It has become like that.

[0003]

As the recycling of such waste containing plastic, the applicant of the present invention has often utilized it as a raw material for solid fuel, as already proposed by the present applicant. Recycled solid fuel from plastic is widely used as a fuel for boilers such as dyeing and bleaching factories and cleaning plants, public baths and health centers, and as a fuel for lime, cement factories and steelworks. I have. However, chlorides such as vinyl chloride, which are widely used, are always contained in waste plastics, and therefore contain regenerated solid fuel, so that dioxin is generated by combustion.

The present invention has been devised in view of the above, and is intended to solidify combustible wastes such as waste plastics, wood chips, paper wastes and the like from offices and homes without polluting them, and to make the solids non-polluting. It is an object of the present invention to provide a plant for detoxifying and regenerating waste, which obtains fuel and coal having many other uses.

[0005]

According to a first aspect of the present invention, there is provided a plant for detoxifying and regenerating waste, which comprises a crushing apparatus for crushing organic waste containing various plastics, A sorting device for sorting valuable materials from the crushed materials, and a plastic and other crushed materials of the crushed materials after the removal of the valuable materials in which the former is 70 to 30% by weight and the latter is 30 to 70% by weight. And compressed while stirring and mixing by feeding by means of a spiral.

And a carbonizing device, wherein the carbonizing device includes an auxiliary burner or a scrubber containing an alkaline aqueous solution in a flue of exhaust gas.

Therefore, in the waste reclaiming and reprocessing plant according to claim 1 having the above structure, PP (polypropylene), PE (polyethylene), PS (polystyrene), PET (polyethylene terephthalate), PA (polyamide), ABS
Organic wastes including various plastics such as (acrylonitrile butadiene styrene) and PVC (polyvinyl chloride) are crushed into fragments by a crushing device so that it is easy to sort valuable materials such as metals in the subsequent process. become. The crushed material after the removal of the valuables is fed by a spiral in a solidifying device, and 70 to 30% by weight of the plastic and 30 to 70% by weight of the crushed material other than the plastic are compressed while being stirred and mixed. At 120 to 300 ° C. The plastic melts without generating dioxin even if it contains chlorine at a temperature in this range, and is kneaded to act as a binder in a flowable state to bind other crushed materials. Therefore, when extruded through a perforated plate, rod-like or granular solids are produced, and these are carbonized by a carbonizer to convert the organic matter into carbon and convert it to versatile coal. The gas containing dioxin generated in the carbonization process of carbonization is completely burned at 800 ° C or more by an auxiliary burner provided in the flue to make it harmless, or dioxin is absorbed by a scrubber containing an alkaline aqueous solution. Is done. Thus, it is possible to obtain non-polluting fuel and coal having many other uses from waste containing plastics.

As described in claim 2, the garbage contained in the waste is sent to a crushing device after being mixed with waste activated carbon generated from waste tires and the like, and the crushed material is supplied with hot gas from the carbonization device. When sent to the drying device used, the bad odor of the garbage is adsorbed by the charcoal to maintain a good working environment, and the moisture is once absorbed by the charcoal to efficiently promote evaporation by the high-temperature gas. Further, the exhaust gas from the carbonization device can be effectively used.

According to a third aspect of the present invention, the oversized garbage and waste wood contained in the waste are crushed by a crusher, and the crushed material is manually separated from the crushed material on a hand-selecting conveyor by a magnetic separator, and the valuable metal is manually processed. Bottles and hazardous materials are sorted out, the remaining crushed materials are removed by a sorting device to remove fine matter such as earth and sand, and the remaining large and medium crushed materials are crushed by a secondary crushing device and then aluminum is removed by an aluminum separator.
If the wood chips and waste plastic are separated by the separation device and supplied to the above-mentioned solidification device after being supplied to the silo with the quantitative feeder once, metals, earth and sand, bottles, and dangerous substances are removed. As a result, a large amount of high-quality organic wood chips suitable for a raw material of charcoal can be secured. In addition, if wood chips and waste plastic are separated and stored in a silo once and then supplied to a solidifying device by a quantitative feeder, the amount of plastic used as a binder can be accurately controlled.

According to a fourth aspect of the present invention, waste plastic, waste paper and / or paper waste contained in the waste is crushed by a crushing device, the magnetic material is separated by a magnetic separator, then crushed by a secondary crushing device, and the air is separated by wind. Once the dust is removed by the device and once supplied to a silo with a quantitative feeder for waste plastic and paper waste and then fed to the solidifying device, waste plastic and paper waste containing a large amount of plastic used as a binder is removed from iron, etc. The magnetic material and dust can be stored in a silo equipped with a quantitative feeder in a state of a crushed piece, and the amount of plastic used as a binder can be accurately controlled by the quantitative supply.

The sewage sludge and human waste sludge and manure sludge contained in the waste are mixed with crushed paper waste and waste activated carbon generated from waste tires and the like after dewatering in a dewatering device, and then solidified in a solidification device. When it is supplied to sewage sludge or manure sludge, which is generally difficult to treat, it can absorb odors by waste activated carbon and convert those organic substances into charcoal that can be used as fuel in a relatively favorable environment.

According to a sixth aspect of the present invention, the waste rubber tire contained in the waste is crushed by a crushing device, supplied to a carbonizing device together with a deoxidizing material such as an iron wire, carbonized by dry distillation, crushed by the crushing device, and then subjected to magnetic separation. If the magnetic material is removed by the machine, waste activated carbon mixed into the plant for treating garbage, sewage sludge, human waste sludge and manure sludge can be supplied by itself.
