Description
본 발명은 유해폐기물의 열분해 가스화 처리 및 잔류회분의 유리화방법과 그 장치에 관한 것으로 더 상세하게는 병원폐기물과 같은 유해성 폐기물을 분리하지 않고 고온으로 용해되어 있는 유리용탕에 직접 투입됨으로써 유리용탕의 고온 열에 의해서 유해폐기물이 열 분해되어 가스와 고형물로 분리되며 분리된 가스는 정제실을 거처 에너지원으로 사용 가능한 연료가스로 되어 분리되고, 고형물은 유리용탕에 용해되어 유리화 된다.The present invention relates to a pyrolysis gasification treatment of hazardous wastes and a vitrification method of residual ash, and more particularly, to a high temperature of glass molten metals by directly inputting them into glass melts dissolved at high temperatures without separating hazardous wastes such as hospital wastes. Hazardous wastes are thermally decomposed by heat and separated into gas and solids. The separated gas is separated into fuel gas that can be used as an energy source through a refinery chamber, and the solid is dissolved in glass molten and vitrified.
또한 고형물 중 금속류는 유리용탕 위에서 용해되어 비중 차에 의해 유리용탕의 하부에 모이게 되고, 모아진 금속분은 금속용탕취출구를 통해 취출되어진다.In addition, the metals in the solid are dissolved on the glass melt and collected in the lower portion of the glass melt due to the difference in specific gravity, and the collected metal powder is taken out through the metal melt outlet.
위와 같은 처리로서 무해한 유리질 고형물 및 금속분으로 분리되는 방법 및 그 장치에 관한 것이다.The above treatment relates to a method and apparatus for separating harmless glassy solids and metal powders.
폐기물을 일반 소각로에서 소각하면 다이옥신 등의 유독 물질이 발생하고 질소산화물 등의 유독가스가 발생하며 소각되지 않은 고형물들이 그대로 남아 있어 2차 공해의 염려가 많았다.Incineration of wastes in general incinerators generates toxic substances such as dioxins, toxic gases such as nitrogen oxides, and solids that are not incinerated, causing high levels of secondary pollution.
다이옥신을 저감하기 위해서는 고온에서 연소시켜 급속히 냉각시키는 방법이 좋으나 950℃이상의 고온에서 공기로 연소시키면 공기중의 질소가 산소와 반응하여 질소산화물이 생겨서 이 질소 산화물을 제거하는데 많은 비용이 소요된다.In order to reduce dioxin, it is preferable to burn at a high temperature and rapidly cool it. However, when burned with air at a temperature of 950 ° C. or higher, nitrogen in the air reacts with oxygen to generate nitrogen oxides, which requires a large cost to remove the nitrogen oxides.
한편, 소각되지 않고 남은 고형물들은 지금까지는 매립장에 매립하고 있으나 이들 고형물들도 부피가 크고 유해물질의 함유 가능성이 커 함부로 매립하기는 어려움이 있었다.On the other hand, the solids that have not been incinerated have been landfilled up to now, but these solids also have a large volume and a high possibility of containing harmful substances, making it difficult to landfill.
또한 이들 종래의 소각에는 공기를 이용하고 있음으로써 연소가스의 양이 상대적으로 많아 연소가스 정화설비의 규모가 커지고 처리비용도 많이 들게 된다.In addition, the use of air for these conventional incinerations results in a relatively large amount of combustion gas, which increases the size of the combustion gas purification equipment and increases the processing cost.
현재 열분해로에서 열 분해시키는 경우 열분해에서 필연적으로 발생하는 용탕을 처리하기 위하여 용탕가열에 필요한 열원은 코크스(cokes)나 산소가스버너에 의한 상부 직접가열방식을 쓰고 있는데 이 방식에서는 용탕 하부의 온도를1500℃이상 유지하기 위해서 용탕 상부온도를 2000℃이상으로 유지하여야 하기 때문에 과도한 열량공급과 분해로의 수명이 문제되고 있다.In the case of pyrolysis in the pyrolysis furnace, the heat source required for the heating of the molten metal is coke (cokes) or oxygen gas burner. Since the upper temperature of the molten metal must be maintained at 2000 ° C or higher in order to maintain the temperature above 1500 ° C, excessive calorie supply and lifetime of the decomposition furnace are problematic.
상기와 같은 문제점을 해소하기 위해 안출된 것으로 유해폐기물의 열분해 가스화 처리 방법 및 그 장치(출원번호 제10-1998-41347호)가 있었으며 그 구성 및 특징을 첨부도면 도 2를 참조하여 설명하면 다음과 같다.In order to solve the above problems, there was a method for treating pyrolysis and gasification of hazardous wastes and an apparatus thereof (Application No. 10-1998-41347).

A high frequency induction apparatus 38 for heating by high frequency induction, and a pyrolysis chamber 22a for thermally decomposing harmful waste 4 by the heat source of the electrically induced metal melting furnace 20a.
상기 투입장치(5)는 유해폐기물(4)이 투입되는 투입구인 홉퍼(10)와, 홉퍼(10)를 통해 투입된 유해폐기물(4)이 적재되는 투입실(11)과, 투입실(11)에 적재된 유해폐기물(4)을 1차 예열하기 위해 유해폐기물(4)을 이동시키는 투입실린더(12a)와, 차폐 상태로 있다가 투입실린더(12a)가 전진할 때에 상부로 이동하는 차폐유압실린더(13a)와, 열분해장치(6)의 건조 및 열분해로(16a)에 적재된 유해폐기물(4)을 이송시키는 이송유압실린더(14a)로 구성된다.The input device 5 is an input chamber 11 into which a hopper 10 into which the hazardous waste 4 is introduced, a hazardous waste 4 introduced through the hopper 10, and an input chamber 11. An injection cylinder 12a for moving the hazardous waste 4 to primaryly preheat the hazardous waste 4 loaded in the container, and a shielding hydraulic cylinder moving upward when the injection cylinder 12a is moved in a shielded state. 13a and a conveying hydraulic cylinder 14a for conveying the hazardous waste 4 loaded in the drying and pyrolysis furnace 16a of the pyrolysis apparatus 6.

A suction blower 35, a gas storage tank 37 storing gas transferred by the gas suction blower 35, and a circulation pump 36 for continuously circulating the washing water in the cooling and washing tower 30. And a sludge transfer pump 31 for transferring a part of the concentrated washing water to the wastewater treatment plant 32.
상기와 같이 구성되어지는 종래의 유해폐기물의열분해 가스화처리 장치는 다음과 같이 작동되어진다.The conventional pyrolysis gasification apparatus for hazardous wastes constituted as described above is operated as follows.
즉, 홉퍼(10)를 통하여 유해폐기물(4)이 투입되어지면 투입실(11)에 쌓이게 되고, 쌓여진 유해폐기물(4)은 투입실린더(12a)의 작동에 의해 건조 및 열분해로(16a)로 떨어 뜨려지게 되며, 이때 차폐유압실린더(13a)가 위쪽으로 작동하여 투입실(11)을 개방시키게 된다.That is, when the hazardous waste 4 is introduced through the hopper 10, it is accumulated in the input chamber 11, and the accumulated hazardous waste 4 is dried and thermally decomposed by the operation of the injection cylinder 12a 16a. It is dropped, and the shield hydraulic cylinder (13a) is operated upward to open the input chamber (11).
건조 및 열분해로(16a)에서 쌓여진 유해폐기물(4)은 가열전원 공급장치(33)의 전열방식에 의해 400~600℃로 가열되고 이 열에 의해 함유수분이나 용제 등과 같은 액상의 물질이 증발되면서 1차로 열분해가스를 발생한다.Hazardous waste (4) accumulated in the drying and pyrolysis furnace (16a) is heated to 400 ~ 600 ℃ by the heat transfer method of the heating power supply device 33 and by this heat liquid substances such as moisture and solvents evaporated 1 Pyrolysis gas is generated by car.
이송유압실린더(14a)의 작동에 의해 유해폐기물(4)은 건조 및 열분해로(16a)에서 열분해실(22a)로 밀려나게 되며, 열분해실(22a)로 밀려난 유해폐기물(4)은 전기유도 금속용융로(20a)에서 고주파 유도장치(38)에 의해 가열코일(H)에서 열이 발생되어 열분해가 이루어지는 지고, 열분해로 인해 가스화되고 가스화되지 안는 금속 고형물은 용융되어 용융금속(ML)으로 생성되어지며, 용융금속(ML)은 냉각되어져 고형폐기물 형태로 방출되고 금속부분은 재활용으로 사용된다.By the operation of the transfer hydraulic cylinder 14a, the hazardous waste 4 is pushed out from the drying and pyrolysis furnace 16a into the pyrolysis chamber 22a, and the hazardous waste 4 pushed into the pyrolysis chamber 22a is electrically induced. In the metal melting furnace 20a, heat is generated in the heating coil H by the high-frequency induction device 38 to pyrolyze, and metal solids which are gasified and not gasified due to pyrolysis are melted to form molten metal (ML). The molten metal (ML) is cooled down and released in the form of solid waste, and the metal part is used for recycling.
분해되어진 가스는 가스정화장치(3)로 유입되어 정화되는 것으로 가스정화장치(3)로 유입된 가스는 냉각 및 세정탑(30)에서 세정수에 의해 냉각되면서 유해가스가 흡수되어 깨끗한 가스로 변환되고 변환된 가스는 가스저장조(37)에 저장되어지며, 냉각 및 세정탑(30)에서는 순환펌프(36)에 의해 세정수를 계속 순환시켜 세정작업을 실시하게되고 농축된 세정수중에 일부는 슬러지이송펌프(31)에 의해 폐수처리장(32)으로 보내어진다.The decomposed gas flows into the gas purifier 3 and is purified. The gas introduced into the gas purifier 3 is cooled by the washing water in the cooling and washing tower 30, and harmful gas is absorbed and converted into a clean gas. The converted gas is stored in the gas storage tank 37. In the cooling and washing tower 30, the washing water is continuously circulated by the circulation pump 36 to perform the washing operation. Part of the concentrated washing water is sludge. It is sent to the wastewater treatment plant 32 by the transfer pump 31.
그러나 상기와 같은 종래의 유해폐기물의열분해 가스화처리 장치는 다음과 같은 문제점이 지적되어진다.However, the following problems of the conventional pyrolysis gasification apparatus for hazardous wastes are pointed out.

한편 열분해실(22)에서 분해된 가스를 1200℃이상으로 가열하기 위한 상부 분해가스가열을 위한 산소버너(23)가 있다.On the other hand, there is an oxygen burner 23 for heating the upper cracked gas for heating the gas cracked in the pyrolysis chamber 22 to 1200 ° C or more.
가스정화장치(3)는 종래의 유해 폐기물의 열분해 가스화 처리장치와 동일한 구성으로 상기 열분해장치(2)의 열분해실(22)에서 분해된 가스가 상부분해가스가열용 산소버너(23)로 가열된 후 유입된 분해가스를 가성소다 액으로 냉각 세정하는 냉각 및 세정탑(30)과 세정된 가스를 이송하는 가스흡입송풍기(35), 세정시 발생하는 슬러지를 이송하는 슬러지이송펌프(31), 슬러지를 처리하는 폐수처리장(32), 가성소다 액을 순환시키는 순환펌프(36), 분리된 분해가스를 저장하는 가스저장조(37)로 구성된다.The gas purifier 3 has the same configuration as a conventional pyrolysis gasification treatment apparatus for hazardous waste, in which the gas decomposed in the pyrolysis chamber 22 of the pyrolysis apparatus 2 is heated by an upper burner gas heating oxygen burner 23. After cooling and cleaning the introduced cracked gas with a caustic soda solution, the cooling tower 30 and the gas suction blower 35 to transfer the cleaned gas, the sludge transfer pump 31 to transfer the sludge generated during the cleaning, sludge It consists of a wastewater treatment plant 32 for treating the gas, a circulation pump 36 for circulating the caustic soda solution, and a gas storage tank 37 for storing the separated cracked gas.
본 발명은 병원폐기물과 같이 대부분 수분이 함유되어 있고 여러 가지 물질이 혼합되어 있으며 전처리가 어렵고 따라서 분리하기가 어려운 유해폐기물(4)을 분리하지 않고 직접 열분해가스화 하는 방식으로 상술한 구성에 의한 작용 및 효과를 살펴보면 다음과 같다.The present invention has the effect of the above-described configuration in such a way as to directly pyrolysis gas without separating the hazardous waste (4), which contains most of the water, such as hospital waste, is mixed with various substances, difficult to pretreat and therefore difficult to separate and The effects are as follows.
유해폐기물(4)이 홉퍼(10)를 통해 투입되어 하부의 투입실(11)에 쌓이게 되면 투입실린더(12)가 전진하면서 유해폐기물(4)을 멸균실(15)로 이송한다 이 멸균실(15)은 폐기물 전체를 멸균할 목적은 아니며 멸균실(15)벽이 150℃이상으로 유지하고 있기 때문에 멸균실(15)에서 밖으로의 오염을 억제하기 위한 목적이 더 크다.When the hazardous waste 4 is introduced through the hopper 10 and accumulated in the lower input chamber 11, the input cylinder 12 moves forward and transfers the hazardous waste 4 to the sterilization chamber 15. 15) is not intended to sterilize the entire waste, but since the walls of the sterilization chamber 15 are maintained at 150 ° C. or more, the purpose for suppressing contamination from the sterilization chamber 15 is greater.
멸균실(15)에 적재되어있던 유해폐기물(4)은 다시 압축실린더(13)에 의해서 압축실(16)로 이송되고, 압축실(16)로 이송된 유해폐기물(4)은 이송유압실린더(14)가 전진하면서 압축하면 압축실(16)의 저단에 설치되어 있는 스크린 망(미도시)에 의해서 일부 수분이 분리되고 계속해서 압축을 받아 열분해실(22)에 밀려나가게 된다.The hazardous waste 4 loaded in the sterilization chamber 15 is again transferred to the compression chamber 16 by the compression cylinder 13, and the hazardous waste 4 transferred to the compression chamber 16 is transferred to the hydraulic cylinder ( When 14) moves forward and compresses, some water is separated by a screen net (not shown) installed at the lower end of the compression chamber 16, and is continuously compressed to be pushed into the pyrolysis chamber 22.
특히, 압축실(16)의 일측은 테이퍼진 형상으로 형성되어져 압축실(16)에 쌓여진 유해폐기물(4)은 이송실린더(14)에 의해 열분해실(22)로 밀려나게 되는데 이때 이송실린더(14)의 로드단부는 일정한 거리(S1)만큼만 전진 및 후퇴를 반복하게 되고, 유해폐기물(4)은 압축실(16)의 단부에서 뭉쳐져 압축실을 폐쇄하게 되어 유체의 흐름을 억제하게 된다.In particular, one side of the compression chamber 16 is formed in a tapered shape so that the hazardous waste 4 accumulated in the compression chamber 16 is pushed into the pyrolysis chamber 22 by the transfer cylinder 14, at which time the transfer cylinder 14 The rod end of the) is repeated forward and backward only by a predetermined distance (S 1 ), the hazardous waste 4 is agglomerated at the end of the compression chamber 16 to close the compression chamber to suppress the flow of the fluid.
압축실(16)에는 압축실린더(13)에 의해 유해폐기물(4)이 재차 유입되어지고, 새로이 유입된 유해폐기물(4)은 이송실린더(14)에 의해 전진하여 단부에 뭉쳐진 유해폐기물(4)을 밀어내게 되고 재차 압축실(16)의 단부를 폐쇄시켜 분해가스가 투입실로 유통되는 것을 억제하는 것이다.The hazardous waste 4 is again introduced into the compression chamber 16 by the compression cylinder 13, and the newly introduced hazardous waste 4 is advanced by the transfer cylinder 14 to be collected at the end of the hazardous waste 4. It pushes out and closes the edge part of the compression chamber 16 again, and suppresses decomposition gas to flow to an input chamber.
열분해실(22)에 투입된 유해폐기물(4)은 유리용탕(21)과 보조산소버너(24)에서 열을 흡수하며 열분해를 일으켜 가연성 복합가스, 유리탄소, 미분해 잔류고형분으로 되는데 복합가스와 유리탄소는 열분해실(22)상부로 이동하여 상부분해가스가열산소버너(23)에 의해서 1200℃이상으로 가열된다. 1200℃이상으로 가열하는 목적은 다이옥신의 분해 및 매연으로 나타나는 유리탄소를 분해하려는 것이다.Hazardous waste (4) introduced into the pyrolysis chamber (22) absorbs heat from the molten glass (21) and the auxiliary oxygen burner (24) and causes thermal decomposition to produce flammable complex gas, free carbon, and undecomposed residual solids. The carbon is moved above the pyrolysis chamber 22 and heated to 1200 ° C or more by the top cracking gas heating oxygen burner 23. The purpose of heating to above 1200 ° C. is to decompose the free carbon which appears as the decomposition and soot of dioxin.
한편 가스화하지 않은 미분해 잔류 고정분은 열분해실(22)하부의 유리용탕(21)위에 떨어져 유리용탕(21)에 용해된다. 이때 유리용탕(21)의 온도는 1550℃이상의 온도를 유지하고 있기 때문에 대부분의 잔류고형분은 유리용탕(21)에 용해되어 유리화 된다. 잔류 고형분 중 금속성분의 고형물은 유리용탕(21)의 열을 받아 용해되어 비중 차로 유리용탕(21)의 하부에 모이게 된다.On the other hand, the undecomposed residual fixed powder which is not gasified falls on the molten glass 21 under the pyrolysis chamber 22 and is dissolved in the molten glass 21. At this time, since the temperature of the glass melt 21 is maintained at a temperature of 1550 ℃ or more, most of the remaining solid content is dissolved in the glass melt 21 and vitrified. The solids of the metal component in the residual solids are dissolved by receiving the heat of the molten glass 21 and are collected in the lower portion of the molten glass 21 by the difference in specific gravity.
잔류고형분이 계속 유리용탕(21)에 용해되면 유리용탕(21)의 액이 증가하는데 이 증가 분만큼 유리용탕취출구(25)를 통해 외부로 취출되고, 금속성분은 금속용탕취출구(26)를 통해 취출된다. 유리용탕(21)은 몰리브덴 가열전극(27)을 통하여 용융유리의 자체전기 저항으로 가열되며 1550℃에서 1600℃사이로 유지되게 유리용해로 전기공급장치(34)에 의해서 조절된다.If the residual solid continues to dissolve in the molten glass 21, the liquid of the molten glass 21 increases, which is taken out to the outside through the molten glass outlet 25 by this increase, and the metal component through the molten metal outlet 26 It is taken out. The molten glass 21 is heated by the molybdenum heating electrode 27 to its own electrical resistance of the molten glass and is controlled by the electric supply device 34 by the glass melting to be maintained between 1550 ° C and 1600 ° C.
열분해실(22)에서 1200℃이상으로 가열되어 냉각 및 세정탑(30)으로 넘어온 분해가스는 열 분해된 유해폐기물(4)의 성상과 열분해실(22)의 조건에 따라 여러 가지 성질과 상태로 되어 나오나 가성소다 액으로 세정하면 염소(Cl), 황산화물 등은 중화되어 세정 액에 흡수되고 세정과정에서 충분한 세정 액을 분사하면 온도도 70℃이하로 냉각된다.The cracked gas heated from the pyrolysis chamber 22 to 1200 ° C. or higher and then passed to the cooling and scrubbing tower 30 may have various properties and states depending on the properties of the thermally decomposed hazardous waste 4 and the conditions of the pyrolysis chamber 22. However, when washed with caustic soda solution, chlorine (Cl), sulfur oxides, etc. are neutralized and absorbed into the cleaning liquid. When sufficient cleaning liquid is injected during the cleaning process, the temperature is also cooled to 70 ° C or lower.
여기에서 열분해실(22)에의 공기유입을 막으면 질소(N2)의 유입을 막게되고 고온의 열분해가스온도에서 질소가 없음으로 질소산화물(NOx)제거설비는 필요 없게 된다.In this case, preventing the inflow of air into the pyrolysis chamber 22 prevents the inflow of nitrogen (N 2 ) and eliminates the need for nitrogen oxide (NO x ) removal equipment because there is no nitrogen at a high temperature of pyrolysis gas.
70℃이하로 냉각되고 세정된 분해가스는 무공해연료로 사용할 수 있는 연료가 됨으로 가스흡입송풍기(31)로 이를 수집 가스저장조(37)에 저장하여 연료로 사용할 수 있고, 양이 적으면 태워버릴 수도 있다.The cracked gas cooled and cleaned below 70 ° C becomes a fuel which can be used as a pollution-free fuel, so that it can be stored as a gas suction blower 31 in a collecting gas storage tank 37 to be used as fuel, and if it is small, it can be burned. have.
냉각 및 세정탑(30)에는 순환수 펌프에 의해 계속 세정수가 순환되고 농축된 세정수의 일부를 폐수처리장(32)에 이송하는 슬러지이송펌프(31)가 장착되어 진다.The cooling and washing tower 30 is equipped with a sludge transfer pump 31 for continuously circulating the washing water by the circulation water pump and transferring a part of the concentrated washing water to the wastewater treatment plant 32.
이상에서와 같이 본 발명에 따른 열분해 및 유리화방법은 유해폐기물(4)을 분리하지 않고 연소에 필요한 공기를 차단한 상태에서 전기 저항가열에 의한 유리용탕의 열에 의해 흡열반응으로 열분해 가스화하고 미분해 고형물은 유리화하며 용융금속은 분리 수집함을 특징으로 하는 것이다.As described above, in the pyrolysis and vitrification method according to the present invention, pyrolysis and gasification by endothermic reaction by heat of glass molten metal by electric resistance heating in the state of blocking the air necessary for combustion without separating the hazardous wastes (4).
