A method for melting eps waste

Abstract

The invention provides a method for melting EPS wastes. The method comprises the following steps that firstly, according to the daily treating capacity of the EPS wastes, a melting box is prepared, one end of the melting box is opened to form a waste inlet, and a melt collecting box is movably placed in the melting box; then the EPS wastes are cleaned, and sundries are removed; then the EPS wastesare placed in the melting box from the waste inlet, an intelligent controller is started, the melting temperature is regulated well, and a high-temperature region is formed in the melting box; afterbeing placed in the melting box, the EPS wastes are melted under the high temperature of the high-temperature zone to form melts; during melting, the produced waste gas is exhausted out by an externalfan from a waste gas outlet, and is transported to the other end of the melting box through a waste gas pipe, so that the waste gas is subjected to high-temperature treatment, and an air circulationis formed in the melting box; and after being fully collected, the melt collecting box is drawn out from the melting box.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a method for melting EPS waste. Background technique [0002] Polystyrene foam board, also known as foam board, EPS board is made of expandable polystyrene beads containing volatile liquid foaming agent. It is a white object that is heated and formed in a mold after heating and pre-expanding. Its structural characteristics are mainly used for building walls, roof insulation, composite board insulation, cold storage, air conditioning, vehicle, ship insulation, floor heating, decoration and engraving, etc. A large amount of waste, if these wastes are discarded directly, it will increase the production cost of the enterprise, and it is not easy to dissolve after discarding, which will cause great adverse effects on the environment; the existing EPS waste (foam) melting machine, such as the foam of the patent No. 2016211709406 The volume reducer, such as the foam me...

Problems solved by technology

[0002] Polystyrene foam board, also known as foam board, EPS board is made of expandable polystyrene beads containing volatile liquid foaming agent, which is a white object that is heated and formed in a mold after heating and pre-expanding. It has fine closed cells. Its structural characteristics are mainly used for building walls, roof insulation, composite board insulation, cold storage, air conditioning, vehicle, ship insulation, floor heating, decoration and engraving, etc. A large amount of waste, if these wastes are discarded directly, it will increase the production cost of the enterprise, and it is not easy to dissolve after discarding, which will cause a greater adverse impact on the environment; the existing EPS waste (foam) melting machine, such as the foam of the patent No. 2016211709406 The volume reducer, such as the foam melting device of the patent No. 20142022616374, when it melts the foam, the exhaust gas generated is directly discharged into the air through the external wind part, causing pollution to the surrounding environment, and both of the above are direct injection The waste heat generated by the flame is directly discharged into the air, resulting in a waste of resources. Both of the above can not achieve the effective utilization of resources and the effect of environmental protection
