Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exhaust gas recycling system,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a harmful gas reduction apparatus for a recycling system, and more particularly, to a harmful gas reduction apparatus for a harmful gas generated in a process of forming an ingot shape by a continuous process through a recycling sorting system for recycling a recyclable product such as waste styrofoam The present invention relates to a harmful gas reduction apparatus for a recycling system that can be easily and quickly reduced using a low-temperature plasma gas generated in a low-temperature plasma.

 As is well known, styrofoam is a material produced by foaming polystyrene and is widely used for packaging materials for electrical and electronic products, building insulation materials, and disposable food containers because of excellent stability, buffering property, and heat insulation property.

Since such a styrofoam is a thermoplastic product, the styrofoam can be recycled relatively easily because it melts when it is heated.

Despite the recycled nature of the styrofoam, it was often buried in the ground due to collection problems. Also, since waste styrofoam contains various foreign substances, a lot of harmful gas is generated when it is recycled.

Landfill sites are gradually decreasing due to the increase of household garbage. Therefore, the local governments are making unremitting efforts to reduce household garbage.

In this way, separate collection has already been generalized, and it is classified and sorted according to the type of waste.

Since the volume of styrofoam is very large as compared with the weight of the styrofoam, the volume of the styrofoam becomes very small and can be recycled.

Many styrofoam containers have been proposed for this purpose. However, despite the demand for styrofoam containers in various municipalities, its frequency of use has not yet been activated. This is because conventional styrofoam containers do not solve the efficiency problem or solve the secondary contamination problem due to the use thereof.

In consideration of this point, recently, an environmentally friendly styrofoam sensitive container has been published in Patent Application No. 10-2006-0095379.

In general, a conventional environmentally friendly styrofoam container is composed of a conveyor formed from the ground to an upper loading port of the hopper for automatic feeding of styrofoam, and two conveying screws installed at a lower portion of the hopper, A crushing means for crushing and conveying the styrofoam at the same time that a plurality of crushing blades forming a virtual helix are coupled to the outer surface of the non-screw portion, A styrofoam is injected into the mold, heating means for heating the styrofoam to melt the molten styrofoam, and a molding frame connected to the extrusion portion to which the molten styrofoam is supplied. The inlet of the molding frame is vertically moved to block the flow of the molten styrofoam Wherein a cutting edge is provided, and at an exit side of the forming die, And a noxious gas processing means for separating and extracting noxious components as they pass through the plurality of chambers while collecting the noxious gas generated in the crushing means, the heating means and the molding means, The styrofoam can be recycled, and all the harmful gas generated during each process is recovered to extract harmful components that can be recycled.

In addition, the eco-friendly styrofoam container may further include a transport line for re-supplying the liquid extract extracted by the noxious gas processing unit to the heating unit, and the heating unit may further include a step of removing impurities A further mesh is installed and configured.

The harmful gas processing means includes a plurality of hoods connected to the discharge ports of the noxious gas generated in the crushing means, the heating means, and the molding means, and a plurality of hoods for collecting noxious gas. A diaphragm is formed in the hood, A plurality of collecting chambers for collecting the harmful components by colliding with the diaphragm so as to collide with the diaphragm; a cooling chamber for enclosing the collecting chambers and supplied with a cooling medium to cool the collecting chambers; And a bubble generator connected to the chamber for discharging the noxious gas into the water to cause the water-soluble residual noxious gas to be collected by the water.

However, the conventional conventional environmentally friendly styrofoam container configured as described above has a problem that the structure for treating harmful gas is too complicated.

That is, a conventional conventional environmentally friendly styrofoam container includes a heating means and a noxious gas treatment means for treating harmful gas, a transport line for re-supplying the liquid extract to the heating means, and a filtering network There is a problem that the configuration becomes complicated.

In addition, the eco-friendly styrofoam container comprises a plurality of collecting chambers, a cooling chamber for cooling the collecting chamber, and a bubble generator, which are provided for treating harmful gas, There is a problem in that not only the manufacturing cost of the bubble generator is increased but also regular maintenance of the components such as the bubble generator is required.
