In addition, the harmful gas treatment means 500 of the present invention includes a bubble generator 540 connected to a collection chamber located at the end of the plurality of collection chambers 520. The bubble generator 540 is to store water to supply harmful gas discharged after passing through a plurality of collection chambers into the water so that the water-soluble residual harmful gas can be collected by the water. A vacuum pump is also provided for forcibly feeding harmful gas from the hood to the bubble generator.

In this way, the harmful gas generated in the shredding means, the heating means and the molding means can be separated by a multi-step harmful component extraction operation, it is possible to reliably solve the environmental pollution problem.

The overall operating principle of the eco-friendly styrofoam reducer according to the present invention will be described schematically. Waste styrofoam is loaded on the conveyor to be introduced into the hopper, and by crushing means, the styrofoam is crushed finely and gradually transferred to the front. The crushed styrofoam is supplied into the heating means and melted by heat, and is supplied into the mold through the extrusion part to fill the mold. When a prescribed amount of molten styrofoam is supplied into the mold, the cutting blade is lowered to block the flow of the molten styrofoam. When the ingot is formed into the shape of the mold by a certain cooling process, the door opens and discharges the ingot.

In particular, harmful gases generated during this continuous process are sucked by the hood and moved to the collection chamber. The collection chamber is connected to several in succession to collect harmful components over multiple stages. Each collection chamber is equipped with a venturi, the harmful gas is accelerated and injected into the collection chamber through the venturi, and harmful components are collected in the liquid phase as the harmful gas collides with the diaphragm formed inside the collection chamber.

A plurality of collection chambers are installed in the cooling chamber, and a cooling medium such as water is circulated and supplied to the cooling chamber to increase the collection efficiency in the collection chamber. In addition, since the harmful gas passing through the collecting chamber located at the end of the plurality of collecting chambers is introduced into the bubble generator and passed through the water, the water-soluble residual harmful gas is collected and separated in the water, and the harmful gas can be completely purified.
