Abstract

PROBLEM TO BE SOLVED: To provide a processing device to effect challenge for zero emission in melting only by energy possessed by itself by effecting thermal decomposition gasification of organic and combustible waste, and to make it possible to use it as a new commercial commodity material with a purpose of re-utilization at a processing process. SOLUTION: By external heating system anoxia carbonization gasification of organic and combustible waste, firstly, the waste is produced as carbide, mixture combustion of the produced carbide is effected and temperature is increased to a high temperature (1500-1700 deg.C). The mixture-burnt production carbide forms flying ash and brought into molten slag in a closed melting furnace. Further, in case it is purposed that the produced carbide is re-utilized as a new commercial commodity material, it is conceived that a part or all thereof can be taken out for re-utilization.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an organic waste or a waste such as plastics, if necessary, partially or
In the process of converting all to carbide or molten slag,
System related to carbonization by the heat energy of waste itself and melting itself. 2. Description of the Related Art A melting furnace for waste such as organic waste or plastics generally uses coke as a heat source using heavy oil, electricity or commercial gas as a heat source, or a treatment method for directly reacting with waste.・ The melting furnace by mixing and burning with coal etc. is present. [0003] (1) For the purpose of recycling, by producing a part or all of the carbide A, an infinite number of new products can be developed. (2) Part or all of the carbide A can be converted into slag and reused as roadbed material / brick, which contributes to zero emission. (3) If a mixed gas generated with coke and coal is used, extra coke and coal ash will be generated, and it is desired to prevent secondary generation of waste. (4) Since it is a continuous integrated device of a heat source from carbonization to melting and from melting to carbonization, it is generally possible to take the challenge of reducing the heat source required for carbonization and melting of combustible waste. [0004] As means for solving the problem, in an external heat type pyrolysis gasification system, the heat required to convert a waste such as organic waste or plastics into a dry distillation gas is disclosed. The difference between the calorie and the calorie required for melting is the sum of the calories produced and the calorie A, that is, the decomposition consumption temperature in the case of the physical external heating type carbonization method is 800 ° C. to 1200 ° C.
° C, and the required melting temperature is 1300 ° C to 1500 ° C or more. Therefore, it is necessary to guide the exhaust gas to the carbonization device L by a high-temperature induction maintaining structure and technology. [0005] It is important that the temperature of the carbide A generated from the carbonization device L be 500 to 600 ° C and co-firing with the carbonization gas effectively in the melting furnace La. [0006] The temperature in the melting furnace La needs to be a furnace having a sustainable shape and form so that the melting temperature at which the heat storage / reflection heat and the melting atmosphere are created and the maximum heat effect is exhibited with the minimum heat energy consumption is achieved. . DETAILED DESCRIPTION OF THE INVENTION A dry distillation gas generated from a carbonization device L is guided to a special gas burner on a melting furnace La, and the carbonization device L
Is mixed and injected with the forced air for gas burner to generate a high temperature by complete combustion, and the mixed and injected carbide A becomes carbonized fly ash and becomes molten slag. The melting furnace La high-temperature exhaust heat is an integrated melting furnace of carbonization and melting that is guided again into the carbonization device L and cycled again as a heat source for generating carbide A. When carbide A is required, it is switched and set to take out part or all, and an integrated carbonization and melting device that can be made simultaneously with melting. An embodiment will be described with reference to the drawings.

The dry-distilled gas generated by the carbonizing device L is supplied to the dry-distilled gas burner C only from the inlet pipe I when (c) a part or all of the carbide A is slagged. (B) Only when all of the carbide A is used as carbide for the purpose of recycling, the carbide A is supplied from the introduction pipe J to the dry distillation gas burner C ′. [0010] The carbide A is supplied to the carbonization device L in the combustion chamber l.
And complete combustion with the dry distillation gas supplied from the furnace, resulting in combustion fly ash.
A melting reaction is performed at 0 to 1700 ° C., and the slag is dropped into a water tank H through a slag tube O. A melting reaction of fly ash and the like occurs in the melting reaction chamber K, and the high-temperature exhaust gas of 1300 to 1500 ° C. passes through a waste heat gas pipe E, and a heating heat source for converting wastes such as organic substances and plastics into dry gas.
