STEAM DIMINISHER HAVING RECYCLING AND FUELING FOR WASTED STYROFOAM FIELD OF THE INVENTION [0001]

The present invention relates to a steam type compression container, and it relates to a steam type compression container which is capable of compressing and decompressing contaminated waste styrofoam, which is difficult to recycle by conventional methods, such as washing and stirring, .

 Styrofoam is used in electronic packaging, transportation containers for fruits and vegetables, farms, construction insulation, etc., and its use is continuously increasing. After using styrofoam, waste styrofoam, which is mostly recycled and recycled by incineration and landfill, is treated with heat and mechanical deterioration. Such methods are toxic gases (such as dioxins), dust, noise and odor .

Styrofoam recycled can not be used as a fuel in spite of high calorific value (over 5,000kcal), and it is mainly used only as recycled plastic through melting process after persimmon. However, it is difficult to sell compressible articles of low quality and it is difficult to sell because of the lack of economical efficiency due to the necessity of additional facilities such as separation facilities.

On the other hand, the domestic technology for the container for recycling the waste styrofoam can be divided into the heat-sensitive technology using the heat wire and the mechanical depressurization technology.

The thermally sensitive container using the hot wire can be used only when the waste styrofoam is not contaminated, and there is a risk of fire due to the use of hot wire, and a malodor occurs during the melting. In addition, there is a disadvantage in that electricity is excessively consumed, and additional facilities are required. In addition, the application of heat technology may cause pollution sources such as carbon dioxide, nitrogen oxides, sulfur oxides, and hydrogen chloride, which may jeopardize environmental pollution and safety of workers.

Since the mechanical pressure vessel uses frictional heat using a high-speed screw, there is a problem that the noise is very high, the compression ratio is low, and it can be used only for recycling waste styrofoam of good quality.
