Description

Manufacturing apparatus for solid fuel using combustible waste}

The present invention relates to a compactor for combustible wastes, and more particularly, to a solid fuel manufacturing apparatus using combustible wastes that pulverizes and compresses general wastes or industrial wastes, and molds them to be processed into solid fuel.

Domestic combustible wastes, which are discharged in the form of food, paper, wood, waste synthetic resins, waste synthetic fibers and waste synthetic leather, amount to about 22 million tons as of 1997. Separate collection is being implemented, and various methods are being implemented in modern times to prevent waste of resources and pollution of the natural environment by separating and recycling each waste.

The waste separated through the separate collection is recycled in various ways depending on the components, waste paper, waste vinyl or plastic containers containing foreign substances have to go through a lot of washing process to be reused after collection, unproductive disadvantage In addition, such industrial waste is burned by incineration or disposed of in the ground, which wastes unnecessary raw materials.

In other words, when waste paper, plastic containers containing waste vinyl or foreign substances are collected and washed to be reused and then reprocessed, the recycling cost is higher than the import price, which leads to additional costs. By incineration or by buried in the ground, there is a problem that wastes valuable resources.

Considering the efficient use of energy and economic aspects among the methods using such a large amount of waste as an energy source, the most practically valid method is to crush flammable solid waste, and then compact it into a specific shape and use it as a solid fuel. It is to use fuel (Refuse-Derived fuel: hereinafter referred to as "RDF").

The above-mentioned RDF generally has calorific value of more than 4,500 kal / kg among combustible solid wastes, and is manufactured from waste synthetic resins, waste papers, and waste woods, and can be used as an alternative energy, and has excellent manufacturing method and storage performance compared to general incineration methods. Therefore, it is possible to solve the problems caused by the use of incineration facilities, and it is a technology that is more economical than liquid or gas fueling technology that requires a lot of investment cost.

In addition, by using the above-described technology, waste resources such as waste synthetic resins, waste papers, and waste wood can be compressed into a press to be reused as fuel.

However, this compactor is manufactured by extruding the RDF into a circular round bar by compression molding the waste synthetic resin, waste paper, waste wood, etc. by applying high temperature and high pressure, so that only the outer side is burned when the molded RDF is burned in an incinerator. The inner side melts and flows down.

It is an object of the present invention to provide an apparatus for producing solid fuel using combustible waste which can produce RDF that can be burned more efficiently when the produced RDF is burned in an incinerator.
