상기 플라즈마 용융로는 용융로(200) 바닥(210)을 따라 오버훌로우되는 슬래그 배출후 바닥(210)에 잔유하는 잔유슬래그배출구(220); 및 상기 배출구(220)를 차단하기 위한 출탕용 차단플러그(230)를 포함하는 플라즈마 용융로를 제공한다.The slag discharge port 220 remaining in the bottom 210 after the slag discharged over the bottom 210 of the melting furnace 200; And it provides a plasma melting furnace comprising a tapping plug 230 for blocking the outlet 220.
슬래그배출구를 통하여 오버훌로우되지 않는 잔유 슬래그 역시 전부 출탕가능하게 할 수 있는 플라즈마 용융로를 제공함.Residual slag that is not overflowed through the slag outlet also provides a plasma melting furnace that can be fully tapped.
Description
본 고안은 플라즈마 용융로(Plasma Furnace)에 관한 것으로 특히, 슬래그배출구와는 별도로 바닥에 잔유하는 잔유슬래그만을 정상운전후 배출키 위한 보조출탕구를 구비한 플라즈마 용융로에 관한 것이다.The present invention relates to a plasma melting furnace (Plasma Furnace), and more particularly, to a plasma melting furnace having an auxiliary tap for the discharge after the normal operation only the residual oil slag remaining on the floor separate from the slag outlet.
첨부 도면 도 1a는 종래 플라즈마 용융로의 종단면도이고, 도 1b는 종래 플라즈마 용융로의 측면도이다.1A is a longitudinal sectional view of a conventional plasma melting furnace, and FIG. 1B is a side view of a conventional plasma melting furnace.
상기 도면에 따르는 종래 플라즈마 용융로는 내화재를 주재료로 소정의 용융로(100)를 형성하고, 그 내부에는 폐기물을 향해 아크를 발생시켜 고온으로 폐기물을 용융시키는 토치(110)를 가지며, 용융된 슬래그를 외부로 배출시키기 위한 슬래그 배출구(120)가 일측벽에 바닥으로부터 소정의 높이를 유지한 상태에서 설치되어 있다.The conventional plasma melting furnace according to the drawings forms a predetermined melting furnace 100 with a refractory material as a main material, and has a torch 110 inside which an arc is generated toward the waste to melt the waste at a high temperature. The slag discharge port 120 for discharging the furnace is provided on one side wall while maintaining a predetermined height from the bottom.
상기한 슬래그 배출구(120)는 플라즈마 용융로를 통하여 용융되는 폐기물중 메탈성분과 슬래그성분중 가벼운 슬래그성분은 용융로 바닥에서 일정높이에 위치하나, 금속성분이 혼합된 가라앉은 성분은 용융로 바닥에 위치한다. 이 상태에서 용융로는 운전을 유지하므로서 소정의 슬래그성분을 소정높이 위치한 배출구를 통하여 배출되나, 그 사이 금속성분의 슬래그는 바닥에서 잔유한 뒤 용융로의 슬래그운전이 끝나면 공냉상태로 바닥에 굳어있게 된다.The slag outlet 120 is a metal slag of the waste melted through the plasma melting furnace and the light slag component of the slag component is located at a certain height at the bottom of the furnace, but the sunk components mixed with the metal components are located at the bottom of the furnace. In this state, while maintaining the operation of the furnace, a predetermined slag component is discharged through an outlet located at a predetermined height, while the slag of the metal component remains in the bottom and solidifies on the floor in an air-cooled state after the slag operation of the furnace is completed.
따라서 용융운전이 끝나고 다시 새로운 용융로 운전이 개시되려면 용융로 바닥에 굳어있는 상기한 금속성분의 슬래그를 깨어내야한다.Therefore, in order to start a new furnace operation after the melting operation is finished, the above-described slag of the metal solidified at the bottom of the furnace must be broken.
금속성분이 포함된 상기 슬래그는 견고하게 응고되어 있어 상당한 작업을 요한다.The slag containing the metal component is solidified and requires considerable work.
이와같이 용융로 운전상의 초기에 용융로 바닥에 응고되어 있는 금속성분의 응고슬래그를 일일이 깨어내는 일을 개선함이 피룡하였다.As such, it was difficult to improve the agitation of the solidified slag of the metal component solidified on the bottom of the furnace in the early stage of operation of the furnace.
본 고안의 목적은 용융로의 슬래그층간분리를 이용하여 상층부의 슬래그는 정상출탕을 유도하고, 잔유하는 금속성분이 혼합된 슬래그는 보조출탕구를 통하여 출탕토록하는 용융로를 제공하는 데에 그 목적이 있다.The object of the present invention is to provide a melting furnace in which the slag of the upper layer leads to normal tapping by using the slag interlayer separation of the melting furnace, and the slag mixed with the remaining metal components is tapping through the auxiliary tapping hole. .

이와같은 본 고안의 목적은 용융로 바닥을 따라 오버훌로우슬래그 배출후 바닥에 잔유하는 잔유슬래그배출구; 및 상기 배출구를 차단하기 위한 출탕용 차단플러그를 포함하는 플라즈마 용융로로서 달성된다.The purpose of the present invention is a residual slag discharge port remaining on the bottom after the discharge of the overflow slag along the bottom of the furnace; And a tapping plug for tapping off the outlet.
따라서 본 고안은 용융운전이 끝남과 동시에 보조 출탕구를 통하여 금속성분의 슬래그가 이미 출탕되어 버려 새로운 용융로 운전을 개시하더라도 종래 처럼 일일이 용융로 바닥에 굳어있는 금속성분의 슬래그를 제거할 필요가 없게 된다.Therefore, the present invention does not need to remove the metal slag solidified at the bottom of the melting furnace as conventionally, even if the slag of the metal component has already been tapped through the auxiliary tapping hole at the same time as the melting operation is finished.
이하 본 고안의 바람직한 실시예를 첨부 도면에 의거 상세하게 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
첨부 도면중 도 2a는 본 고안 플라즈마 용융로의 종단면도이고, 도 1b는 본 고안 플라즈마 용융로의 측면도이다.2A is a longitudinal cross-sectional view of the present invention plasma melting furnace, and FIG. 1B is a side view of the present invention plasma melting furnace.
상기한 도면들에 따르는 본 고안의 플라즈마 용융로(200)는 내화재를 주재료로 소정의 용융틀을 형성하고, 그 내부에는 폐기물을 향해 아크를 발생시켜 고온으로 폐기물을 용융시키는 토치(250)를 설치하며, 용융된 슬래그를 외부로 배출시키기 위한 슬래그 배출구(220)가 일측벽에 바닥(210)으로부터 소정의 높이를 유지한 상태에서 설치된다. 특히 이와같은 용융로(200)의 바닥(210)의 수평선상으로 보조출탕구(230)을 관통설치하며, 이 출탕구(230)는 차단플러그(240)으로 개폐된다.Plasma melting furnace 200 of the present invention according to the above drawings to form a predetermined melting frame with the refractory material as a main material, there is installed a torch 250 for melting the waste at a high temperature by generating an arc toward the waste In addition, the slag discharge port 220 for discharging the molten slag to the outside is installed on a side wall while maintaining a predetermined height from the bottom 210. In particular, the auxiliary tapping hole 230 is installed through the horizontal line of the bottom 210 of the melting furnace 200, and the tapping hole 230 is opened and closed by the blocking plug 240.
상기한 슬래그 배출구(220)는 플라즈마 용융로(200)를 통하여 용융되는 폐기물중 메탈성분과 슬래그성분중 가벼운 슬래그성분은 용융로 바닥에서 일정높이에 위치하나, 금속성분이 혼합된 가라앉은 성분은 용융로 바닥에 위치한다. 이 상태에서 용융로는 운전을 유지하므로서 소정의 슬래그성분은 소정높이 위치한 배출구(220)를 통하여 배출되나, 그 사이 금속성분의 슬래그는 보조출탕구(230)을 통하여 배출된다. 따라서 바닥에는 슬래그운전이 끝나더라도 종래 처럼 잔유슬래그가 공냉상태로 굳어있지 않고, 말끔하게 바닥을 유지하게 된다.The slag outlet 220 is a light slag component of the metal component and the slag component of the waste that is melted through the plasma melting furnace 200 is located at a certain height at the bottom of the furnace, but the sinking component mixed with the metal component is at the bottom of the furnace Located. In this state, while maintaining the operation of the furnace, the predetermined slag component is discharged through the outlet 220 positioned at a predetermined height, while the slag of the metal component is discharged through the auxiliary tapping hole 230. Therefore, even after the slag operation is completed, the remaining oil slag is not solidified in the air-cooled state as before, and the floor is neatly maintained.
이와같이 본 고안은 슬래그배출구를 통하여 오버훌로우되는 슬래그가 출탕되면서도 용융로 바닥에 잔유하는 금속성분의 잔유 슬래그 역시 보조출탕구를 통하여 배출되므로서 종래 바닥에 잔유하는 금속성분의 슬래그가 공냉응고됨에 따른 용융로 운전상의 문제점을 개선하게 되는 효과가 있다.Thus, the present invention is a melting furnace according to the slag of the metal component remaining on the bottom of the conventional floor because the slag of the metal overflows through the slag discharge port is also discharged through the auxiliary tap opening while the slag of the metal component remaining on the bottom of the melting furnace is tapping out There is an effect to improve the driving problems.
