Description

Equipment for dryer to waste and extracting an oil from the plastic waste that is linked to waste incinerator}

The present invention is a comprehensive treatment system for comprehensive treatment of various industrial wastes and household wastes. The present invention relates to a drying facility for drying a large number of wastes such as food waste in connection with an incinerator, and an emulsification facility for recycling waste plastics.

As of 2000, domestic wastes were about 4,600 thousand tons per day, and the recycling rate through separate collection was about 41.3%.

However, after the landfill is disposed of, it causes odors caused by nitrogen and sulfur compounds and insect breeding such as fly mosquitoes, and high concentration of leachate is generated, which incurs additional treatment costs and damages to health if mistreated. There was a problem that caused the problems of water quality and air pollution caused by leachate.

In addition, domestic waste incinerators installed in Korea are not easy to incinerate wastes containing many parts, and a separate drying facility is required, and energy consumption is intensified by heating them with separate heating means such as burners. .

Therefore, the two-stage process of reducing waste and recycling of food waste and multi-part wastes is expanding the resource-based infrastructure of public institutions and private companies.However, there are problems of separate collection and over-use and economic reasons for landfill after drying. Due to its efficiency is falling.

In addition, plastics and vinyl have become an indispensable necessity for life, and the kind and use of the products have been soared due to the development of petrochemicals, and the amount of plastics and vinyl discarded is increasing rapidly.

However, waste plastics are being recycled through separate collection, but since the types are large, many waste plastics such as waste vinyl, plastic bags and packaging containers are treated like general wastes, but the landfilling method takes a long time to decompose plastics. It takes a long time and takes up a lot of volume, so it is difficult to landfill, and the method of incineration of waste plastics can obtain a large amount of thermal energy, but it is true that a large amount of pollutant is discharged, and thus there is a limit to incineration.

In addition, when incineration occurs when waste plastics are incinerated, they are stuck to the grate and firebrick as incinerators, causing frequent failures.

Therefore, a method of recycling waste plastics is being studied. Among them, by thermally decomposing at a specific temperature by applying heat to plastics, which are high molecular weight compounds, various low molecular weight compounds are produced to condense the vaporized vapor to vaporize the oil vaporized. How to extract.

However, in order to thermally decompose the waste plastic, a high temperature is required, so the oil is extracted to be heated by a separate heating means such as a burner, and thus, economic efficiency is low and efficiency is reduced.

Thus, the present invention was devised to solve the problems described above, by drying the waste by using the high temperature waste heat generated in the combustion chamber of the food waste and a large number of waste, incineration by transporting the resources or incinerator In addition, since the waste plastics are pyrolyzed to extract oil and used as a heat source of the incinerator, no additional energy is required, and an object of the present invention is to provide a comprehensive waste treatment facility that can reduce the associated costs associated with drying and incineration.
