Description

폐합성수지 소각장치와 이를 이용한 대체 연료형 산업용 보일러Waste synthetic resin incinerator and alternative fuel type industrial boiler

본 발명은 폐합성수지 예를 들면 폐타이어 등의 폐고무류를 소각시키는 시스템에 관한 것으로서, 폐고무류 등을 단열처리된 소각로와 1차 및 2차 연소로에서 고온집중방식으로 연소시킴으로써 고효율을 확보하고 다이옥신 등의 2차 오염물질 배출을 극소화시킬 수 있게 하며, 또한 열교환기를 이용해서 상기 발생된 고온의 열로 난방수를 공급할 수 있도록 한 보일러 시스템에 관한 것이다.The present invention relates to a system for incineration of waste rubber such as waste synthetic resins, for example, waste tires, and ensures high efficiency by burning waste rubber and the like in a thermally insulated incinerator and primary and secondary combustion furnaces at high temperature. The present invention relates to a boiler system capable of minimizing secondary pollutant emissions, and the like, and to supply heating water with the generated high temperature heat using a heat exchanger.

종래에 폐자재를 소각시키는 장치는 단순 소각로 구실만 하기 때문에 고열을 발생시키기 어려운 구조이다.Conventionally, a device for incineration of waste materials has a structure that is hard to generate high heat because only the incinerator serves.

이 것은 폐자재를 소각시킬 때 발생하는 열이 소각로 외벽체를 방열체로 하여 대기중으로 방열되기 때문이며, 소각로 외벽체로 열이 방사되기 때문에 로체 내부를 고온으로 만들기 어렵고, 로체 외부의 발산 온도는 최고부위가 섭씨 300도 이상 발산하기 때문에 화상등의 위험성도 따랐다.This is because the heat generated by incineration of waste materials is radiated to the atmosphere with the incinerator outer wall as a heat sink, and because the heat is radiated to the outer wall of the incinerator, it is difficult to make the inside of the furnace at a high temperature. Because it sheds more than 300 degrees, the risks such as burns were also followed.

또한, 정화기의 배출온도는 섭씨 800도 이하이기 때문에 완전연소는 불가능하고, 불완전 연소로 인하여 다이옥신 등의 2차 오염물질이 배출되는 단점이 있다.In addition, since the discharge temperature of the purifier is 800 degrees Celsius or less, complete combustion is impossible, and secondary pollutants such as dioxins are discharged due to incomplete combustion.

본 발명은 폐자재 특히 폐고무류를 연소시켜서 발생된 열을 단열 처리된 연소로 속에서 외부 방열이 차단된 상태로 고온화하여 처리함으로써 실질적인 완전연소를 확보하여 다이옥신 등의 2차 오염물질 발생을 예방함과 함께, 고온화된 열을 열교환기를 이용해서 보일러 시스템으로 활용할 수 있도록 한 폐합성수지 소각 시스템을 제공한다.The present invention prevents the generation of secondary pollutants such as dioxin by securing substantial complete combustion by treating the waste materials, in particular the heat generated by burning the waste rubber to a high temperature in a state that the heat dissipation is blocked in a heat-insulated combustion furnace in the state of the heat dissipation In addition, it provides a waste synthetic resin incineration system that can be used to heat the heated heat to the boiler system using a heat exchanger.

도1은 본 발명의 일실시예로서 쓰레기 소각열을 이용한 산업용 보일러의 외관을 개략적으로 나타낸 도면이다.1 is a view schematically showing the appearance of an industrial boiler using waste incineration heat as an embodiment of the present invention.

가스발생로(101)는 원통형이고 단열연와로 내벽이 단열처리된 구조이며, 폐고무류를 소각시키는 장치로서 내부에 건류실을 가지고 있고, 폐고무류에 점화하여 폐고무류를 건류시켜서 가스를 발생시킨다.Gas generating furnace 101 has a cylindrical shape and the insulation wall of the inner wall is insulated treatment, as a device for incineration of waste rubber has a drying chamber inside, ignited in the waste rubber to dry the waste rubber to generate gas.

1차 연소로(102)는 원통형으로서 연결관(103)을 이용해서 상기 가스 발생로(101)와 연결되며, 가스 발생로(101)에서 발생된 가스가 주입되어 열분해로 인한 완전연소 작용을 수행하고, 내벽이 단열연와로 단열처리된다.The primary combustion furnace 102 is cylindrical and connected to the gas generating furnace 101 by using a connecting tube 103, and the gas generated in the gas generating furnace 101 is injected to perform a complete combustion operation due to pyrolysis. The inner wall is insulated with adiabatic edges.

2차 연소로(104)는 원통형으로서 열교환기를 함께 내장하며, 연결관(105)을 이용해서 상기 1차 연소로(102)와 연결되고 먼지 집진 제거를 위한 사이클론(106)이 최종 배출단에 설치되며, 1차 연소로(102)로부터 주입되는 고온의 가스를 2차 연소시키고, 열교환기를 통해서 난방수를 공급한다.The secondary combustion furnace 104 is cylindrical and contains a heat exchanger together, and is connected to the primary combustion furnace 102 using a connecting pipe 105 and a cyclone 106 for removing dust collection is installed at the final discharge end. Then, the high temperature gas injected from the primary combustion furnace 102 is secondary burned, and heating water is supplied through the heat exchanger.

도2는 상기 도1의 보일러 시스템의 주요 부분을 단면처리하여 도시한 도면이다.FIG. 2 is a cross-sectional view illustrating a main part of the boiler system of FIG.

가스 발생로(101)는 건류실(201)을 가지며, 로 전체를 감싸는 철판(202)을 외벽으로 하고 단열연와(203)를 내벽으로 하며 도어(204)가 설치되고, 건류실의 하단부 일측으로 연소를 위한 순환가스가 주입되는 순환가스입구(205)를 가지는 한편, 건류실의 상단에는 내부압력이 임계치에 도달하였을 때 열리는 방폭구(206)를 구비한다.The gas generating furnace 101 has a distillation chamber 201, an iron wall 202 covering the entire furnace as an outer wall, a heat insulation edge 203 as an inner wall, and a door 204 is installed, and one side of the lower end of the distillation chamber. While having a circulating gas inlet 205 into which the circulating gas for combustion is injected, the upper end of the distillation chamber is provided with an explosion-proof opening 206 that opens when the internal pressure reaches a threshold.

가스 발생로(101)의 내부 건류실(201)에는 연소용 연료가 되는 폐고무류 등의 폐합성수지를 장전하고, 이 폐고무류를 점화하여 폐고무류를 건류시켜서 가스를 발생시킨다.The internal drying chamber 201 of the gas generating path 101 is loaded with waste synthetic resin such as waste rubber serving as fuel for combustion, and the waste rubber is ignited to dry the waste rubber to generate gas.

이때, 순환가스입구(205)를 통해서 순환가스가 주입되고, 건류실(201)의 내부압력이 소정의 임계치에 도달하면 방폭구(206)가 열려줌으로써 방폭 작용을 하도록 하였다.At this time, when the circulating gas is injected through the circulating gas inlet 205 and the internal pressure of the distillation chamber 201 reaches a predetermined threshold, the explosion-proof opening 206 is opened to act as an explosion protection.

건류실(201)내에서의 연소시에 발생되는 열은 단열연와(203)에 의해서 단열되기 때문에 로체 외부로 발산되는 열의 온도는 환경 기준치 섭씨 80도 보다도 매우 작은 섭씨 40도 미만의 발산온도를 유지한다.Since the heat generated during combustion in the distillation chamber 201 is insulated by the insulation edge 203, the temperature of the heat dissipated outside the furnace is kept at an emission temperature of less than 40 degrees Celsius, which is much smaller than the environmental standard of 80 degrees Celsius. do.

그러므로, 가스 발생로(101) 내에서 소각되는 폐고무류는 고온의 열이 집중되는 상태로 소각되고, 여기서 발생되는 가스성분은 고온집중상태로 연결관(103)을 통해서 1차 연소로(102) 측으로 주입된다.Therefore, the waste rubber incinerated in the gas generating furnace 101 is incinerated in a state where high temperature heat is concentrated, and the gas component generated here is the primary combustion furnace 102 through the connecting pipe 103 in a high temperature concentrated state. Is injected into the side.

1차 연소로(102)는 외벽이 철판(207)이고 내벽은 단열연와(208)이며, 내부에는 상기 가스 발생로(101)로부터 주입되는 가스가 연소되는 연소실(209)을 가진다.The primary combustion furnace 102 has an outer wall of an iron plate 207, an inner wall of an insulating edge 208, and has a combustion chamber 209 in which gas injected from the gas generating furnace 101 is combusted.

그리고, 도시 생략된 송풍수단에 의해서 연소용 공기를 불어넣기 위한 1차 노즐(210), 2차 노즐(211), 3차 노즐(212)이 구비되며, 가스발생로로부터 주입된 가스를 완전 연소시키기 위한 보조버너(213)가 장착되어 있다.In addition, a primary nozzle 210, a secondary nozzle 211, and a tertiary nozzle 212 are provided for blowing air for combustion by a blowing means (not shown), and the gas injected from the gas generating furnace is completely burned. The auxiliary burner 213 is mounted.

1차 연소로(102)의 연소실(209)안으로 가스 발생로(101)로부터 주입된 가스는 보조버너(213)에 의해서 연소실(209)내부를 고온으로 올려서 가스를 완전 연소시킴과 함께, 1차 노즐(210)과 2차 노즐(211) 및 3차 노즐(212)을 통해서 주입되는 공기에 의해서 연소시킨다.The gas injected from the gas generating furnace 101 into the combustion chamber 209 of the primary combustion furnace 102 raises the inside of the combustion chamber 209 to a high temperature by the auxiliary burner 213 to completely burn the gas, and It is burned by the air injected through the nozzle 210, the secondary nozzle 211, and the tertiary nozzle 212.

이때 단열연와(208)에 의해서 1차 연소로가 단열되기 때문에 1차 연소로(102)의 내부 연소실(209)은 고온집중상태로 유지되고, 그러므로 여기서 연소되는 가스는 초고온에 의해서 완전연소된다.At this time, since the primary combustion furnace is insulated by the adiabatic edge 208, the internal combustion chamber 209 of the primary combustion furnace 102 is maintained at a high temperature concentration, and therefore the gas burned here is completely burned out by the ultra high temperature.

1차 연소로(102)를 통과한 고온의 열과 가스(폐열)는 연결관(105)을 통해서 다시 2차 연소로(104)에 공급된다.The high temperature heat and gas (waste heat) passing through the primary combustion furnace 102 are supplied to the secondary combustion furnace 104 through the connection pipe 105 again.

2차 연소로(104)는 철판재의 벽체로 원통형이며, 1차 연소로(102)에 연결되는 부분에 2차 연소실(214)이 구비된다.Secondary combustion furnace 104 is a cylindrical wall of the iron plate material, the secondary combustion chamber 214 is provided at a portion connected to the primary combustion furnace (102).

2차 연소실(214)은 벽체가 단열연와(215)로 구성되며, 2차 연소실(214)에서 연소된 폐열을 이용한 열교환기(216)가 2차 연소실내에 구비되는데, 이 열교환기(216)는 약 30개의 관으로 이루어지고, 관의 일단으로는 난방수 주입구(217)가 구비되고 그 타단으로는 난방수 배출구(218)가 구비된다.The secondary combustion chamber 214 has a wall composed of adiabatic edges 215, and a heat exchanger 216 using waste heat burned in the secondary combustion chamber 214 is provided in the secondary combustion chamber. Is composed of about 30 tubes, one end of the tube is provided with a heating water inlet 217, the other end is provided with a heating water outlet 218.

또한, 2차 연소로(104)에는 2차 연소실(214)에서 연소된 가스의 배출구(219)가 구비되어 사이크론(106)으로 연결된다.In addition, the secondary combustion furnace 104 is provided with an outlet 219 of the gas combusted in the secondary combustion chamber 214 is connected to the cyclone 106.

1차 연소로(102)로부터 2차 연소로(104)의 2차 연소실(214)로 주입된 가스는 화염상태로 투입되며, 단열연와(215)에 의해서 고온집중된 상태로 연소처리되어 섭씨 1300도 이상의 고온으로 완전연소가 이루어지고, 여기서 연소시에 발생된 고온의 열은 2차 연소로(104)내부를 회전하면서, 난방수 주입구(217)로부터 열교환기(216)를 통과하는 난방수를 데워서 난방수 배출구(218)로 배출하게 함으로써 보일러 시스템으로 기능하게 된다.The gas injected from the primary combustion furnace 102 into the secondary combustion chamber 214 of the secondary combustion furnace 104 is introduced into the flame state, and is burned in a high-temperature concentrated state by the adiabatic edge 215 to be 1300 degrees Celsius. The complete combustion is performed at the above-described high temperature, and the high temperature heat generated during the combustion heats the heating water passing through the heat exchanger 216 from the heating water inlet 217 while rotating inside the secondary combustion furnace 104. By discharging to the heating water outlet 218 it functions as a boiler system.

2차 연소로(104)내부를 회전하여 최종적으로 가스 배출구(219)로 배출되는 가스는 사이크론(106)을 통해서 먼지 집진제거된 다음 대기중으로 배출된다.Gas that is rotated inside the secondary combustion furnace 104 and finally discharged to the gas outlet 219 is dust-collected through the cyclone 106 and then discharged to the atmosphere.

사이크론(106)은 철판재의 벽체를 가지며, 내부에 연도(220)를 가지는 굴뚝형태로서, 사이크론(106)을 통과한 최종 화염온도는 섭씨 200도 이하임을 확인하였다.Cyclone 106 has a wall of the iron plate, the chimney shape having a flue 220 therein, it was confirmed that the final flame temperature passed through the cyclone 106 is 200 degrees Celsius or less.

본 발명은 폐타이어를 포함하는 폐고무류를 대체 연료로 사용하여 단열처리된 다단계 소각/연소수단을 통과시킴으로써, 고온집중화를 통한 고온의 화염 발생을 가능하게 하였고, 이러한 고온의 화염발생으로 인하여 그 내부의 폐가스의 열분해를 촉진하여 다이옥신 등의 2차 오염물질 배출을 극소화키는 것은 물론, 고온의 열을 이용해서 고효율의 에너지 대체형 보일러 시스템을 제공할 수 있게 하였다.The present invention enables the generation of high temperature flames through high temperature concentration by passing the insulated multi-stage incineration / combustion means using waste rubber including waste tires as an alternative fuel, and because of the high temperature flame generation In addition to minimizing secondary pollutant emissions such as dioxins by promoting the pyrolysis of waste gas, it is possible to provide a high-efficiency energy- replaceable boiler system using high temperature heat.
