본 고안은 산업폐기물을 소각 처리하는 소각로를 이용하여 액상폐기물을 열분해 처리하는 장치에 대한 것이다.The present invention relates to an apparatus for pyrolyzing liquid waste using an incinerator for incineration of industrial waste.

일반적으로 산업폐기물을 고형폐기물과 액상폐기물로 대별된다 할것인바, 가연성 고형폐기물의 경우에 있어서는 일반 소각로를 사용하여 소각 처리하면 되지만 액상폐기물의 경우에는 그대로의 소각처리가 불가하여 먼저 액상폐기물을 탈수시킨 다음 수분(폐수)이 제거된 폐기물을 소각하거나 매립 처리하는 산업폐기물 처리 방식을 이용해 왔었다.In general, industrial wastes are classified into solid wastes and liquid wastes. In the case of flammable solid wastes, incineration may be carried out using a general incinerator, but liquid wastes may not be incinerated as they are, so that liquid wastes are first dehydrated. The following industrial waste treatment methods have been used to incinerate or landfill wastes from which water (wastewater) has been removed.

그러나, 상기와 같이 수분을 포함하는 액체가 다량 함유된 액상폐기물의 처리방식을 액상폐기물로부터 수분을 제거하여 분리 처리해아 하는 번거로움은 물론 액상폐기물로 부터 탈수한 유독성분이 다량 함유된 폐수의 처리문제가 용이치 않은 문제점이 있었다.However, the problem of treating wastewater containing a large amount of toxic components dehydrated from the liquid waste, as well as the hassle of separating and treating the liquid waste containing a large amount of liquid containing water as described above to remove the water from the liquid waste. There was a problem that was not easy.

본 고안은 상기와 같은 액상폐기물을 고온 열분해 방법으로 한번에 처리할수 있는 장치를 제공함에 목적이 있는 것으로 이를 첨부도면에 의거 상세히 설명하면 다음과 같다.The present invention has an object to provide a device that can treat such liquid waste at a time by a high temperature pyrolysis method described in detail based on the accompanying drawings as follows.

소각로(1)를 이용하여 일반 사업폐기물을 소각처리하는 과정은 공지와 같으나, 본 고안에서는 소각로(1)의 냉각수단으로서 별도의 냉각수를 사용하지 않고 노의 온도를 일정하게 유지시키면서 액상폐기물을 동시 처리 가능토록 구성된 본 장치는 폐기물을 소각시키기 위한 소각로(1)와, 폐기물의 소각시 발생하는 연소가스에 포함된 연소재를 집진하기 위한 원심집진장치(2)와, 연소가스에 포함된 유해가스를 흡수시켜 주는 세정탑(3)으로 구성되며, 상기 소각로(1)와 원심집진장치(2)사이에는 다수의 연소가스 배기관(4)이 내설되고 그 저부에 설치되는 슬러리호퍼(5)에 압송펌프(6)를 장착한 폐수증발기(7)가 설치된다.The process of incineration of general business wastes using the incinerator (1) is the same as known, but in the present invention, liquid wastes are simultaneously maintained while maintaining a constant temperature of the furnace as a cooling means of the incinerator (1). The apparatus, which is configured to be treated, includes an incinerator (1) for incineration of waste, a centrifugal dust collector (2) for collecting the combustion material contained in the combustion gas generated during incineration of the waste, and a harmful gas contained in the combustion gas. It consists of a washing tower (3) for absorbing the water, and a plurality of combustion gas exhaust pipe (4) is built between the incinerator (1) and the centrifugal dust collector (2) and pumped to the slurry hopper (5) installed at the bottom A wastewater vaporizer 7 equipped with a pump 6 is provided.

이 폐수증발기(7)의 상부에는 그 출구가 소각로(1)의 1, 2차 연소실에 위치하는 증기공급관(8)이 설치되어 있으며, 상기 슬러리 호퍼(5)에 설치되는 압송펌프(6)에는 그 출구가 소각로(1)의 1, 2차 연소실에 위치토록 구성된 슬러리공급관(9)이 설치되어 있다.In the upper part of the waste water evaporator 7, a steam supply pipe 8 whose outlet is located in the first and second combustion chambers of the incinerator 1 is installed, and the pressure pump 6 installed in the slurry hopper 5 is provided. The slurry supply pipe 9 is provided so that the outlet is located in the primary and secondary combustion chambers of the incinerator 1.

상기 증기공급관(8)과 슬러리공급관(9)의 출구에는 분사노즐을 구비시켜 액상폐기물이 증발하면서 발생하는 증기의 고른분사가 이루어지도록 하는 한편, 압송펌프(6)에 의해 슬러리 공급관(9)을 통해 이송되는 슬러리의 분사배출이 이루어지도록 하였다.Injection nozzles are provided at the outlets of the steam supply pipe 8 and the slurry supply pipe 9 to allow even spraying of steam generated while the liquid waste evaporates, and the slurry supply pipe 9 is formed by the pressure feed pump 6. Spray discharge of the slurry transported through was made.

미설명 부호 12는 고형 산업 폐기물을 소각로(1)에 투입시키기 위한 투입구이며, 14는 계단상을 구성되어 전후방향(도면상 좌우)으로 왕복요동하면서 그위에 얹혀진 연소중인 폐기물을 이송시켜 주는 로스톨이고, 13은 감시 카메라이다.Reference numeral 12 denotes an inlet for injecting solid industrial waste into the incinerator 1, and 14 denotes a stole which forms a staircase and reciprocates in the front-rear direction (left and right in the drawing) and transports the combustion waste placed thereon. And 13 is a surveillance camera.

이와같은 구성을 보이는 본 장치는 다음과 같은 작용을 통해 액상폐기물을 소각처리하게 된다.The device exhibiting such a configuration incinerates liquid waste through the following actions.

산업상 생긴 산업폐기물을 가연성과 비가연성으로 분리하여 가연성 폐기물을 투입호퍼(10)에 집어넣어 유압식 또는 반자동으로 일정량의 폐기물을 연속적으로 소각로(1)에 투입한다.The industrial waste produced in the industry is separated into combustible and non-combustible, and the combustible waste is put into the input hopper 10, and a certain amount of waste is continuously injected into the incinerator 1 hydraulically or semi-automatically.

또한, 수분이 다량 함유된 액상폐기물을 폐수증발기(7)에 투입한다.In addition, the liquid waste containing a large amount of water is injected into the wastewater evaporator (7).

그다음 착화버너(11)를 점화시켜 소각로(1)에 투입된 가연성 폐기물을 소각시킨다.The ignition burner 11 is then ignited to incinerate the combustible waste introduced into the incinerator 1.

이때 발생하는 건류연소가스는 소각로(1)상부의 2차 연소실에서 재연소를 이루면서 연소가스배기관(4)을 통해 배출되게 되는데, 연소가스가 폐수증발기(7) 내부를 관통하는 연소가스배기관(4)을 지나면서 폐수증발기(7) 내의 액상폐기물을 가열하게 된다.At this time, the dry combustion gas generated is discharged through the combustion gas exhaust pipe 4 while re-burning in the secondary combustion chamber above the incinerator 1, and the combustion gas exhaust pipe 4 through which the combustion gas passes through the waste water evaporator 7. Passing through) will heat the liquid waste in the wastewater evaporator (7).

한편, 일반적으로 소각로(1)를 구성하는 내화제는 약 1100-1200℃까지 견딜수 있도록 설계되기 때문에 종래 소각로(1)에는 냉각수를 순환시켜 소각로(1)의 내부온도를 조절해 왔었다.On the other hand, in general, since the refractory material constituting the incinerator (1) is designed to withstand up to about 1100-1200 ° C, the incinerator (1) has conventionally regulated the internal temperature of the incinerator (1) by circulating cooling water.

즉, 아무런 냉각수단을 구비하지 않고 그래도 폐기물을 연소시키게 되면 소각로의 내부온도가 1300℃이상 오르게 되어 소각로를 훼손시키게 되는 것이다.In other words, if the waste is still burned without any cooling means, the internal temperature of the incinerator rises to 1300 ° C. or more, thereby damaging the incinerator.

그러나, 본 고안에서는 종래 냉각수 순환방식에 의한 냉각방식을 이용하지 않고, 액상폐기물을 분사연소시켜 냉각효과를 거둠과 동시에 액상폐기물을 소각처리함으로써 일석이조의 효과를 득할수 있게 되었다.However, in the present invention, the cooling effect of the conventional cooling water circulation method is not used, and the liquid waste is jetted and burned to achieve a cooling effect, and at the same time, the liquid waste is incinerated, thereby obtaining the effect of two stone two tanks.

이를 좀도 상세히 설명하면, 소각로(1)에서 발생하는 건류연소가스가 폐수증발기(7)를 지나면서 이 폐수증발기(7)에 투입된 액상폐기물을 가열하게 되므로 액상폐기물에 함유된 수분(폐수)이 증발하여 증기공급관(8)으로 배출되게 된다.To explain this in more detail, the dry burning gas generated in the incinerator 1 heats the liquid waste introduced into the wastewater evaporator 7 while passing through the wastewater evaporator 7 so that the water (wastewater) contained in the liquid waste is discharged. Evaporated to be discharged to the steam supply pipe (8).

이 증기공급관(8)의 출구는 소각로(1)의 1, 2차 연소실에 위치하고 있어 증발된 폐수증기를 소각로(1)에 분사(분무)시키게 된다. (증기 공급관 출구에 설치된 도시되지 않는 분사노즐에 의해 배출되는 폐수증기의 분사가 이루어짐)The outlet of this steam supply pipe 8 is located in the 1st and 2nd combustion chambers of the incinerator 1, and injects (sprays) the vaporized waste water vapor to the incinerator 1. (The injection of the waste water vapor discharged by an unshown injection nozzle installed at the outlet of the steam supply pipe is performed.)

그런데 증기공급관(8)을 통해 소각로(1)내로 분사배출된 폐수증기는 고온에서 불완전 연소로 발생된 탄소(C)와 작용하여 1산화탄소(CO)와 수소(H2)가 발생되고 과일공기중 산소와 반응하여 연속적으로 1산화탄소(CO) 및 수소(H2)인 수성가스가 발생, 재연소되어 일정이상의 고온을 유지하므로 산업폐기물의 완전 연소효율을 촉진하게 된다.However, the waste water vapor injected into the incinerator 1 through the steam supply pipe 8 acts with carbon (C) generated by incomplete combustion at high temperature to generate carbon monoxide (CO) and hydrogen (H 2 ) and fruit air. Water gas, which is carbon monoxide (CO) and hydrogen (H 2 ), is continuously generated and reacted with heavy oxygen to maintain a high temperature above a certain level, thereby promoting complete combustion efficiency of industrial waste.

한편, 소각로(1)의 내부온도가 계속 상승하여 일정온도(900-1200℃)에 이르게 되면 소각로(1)에 설치된 도시되지 않은 온도센서의 작용으로 슬러리호퍼(5)에 설치된 압송펌프(6)가 가동하여 소각로 내부로 슬러리를 분사시키게 되므로 소각로(1)의 내부온도가 하강되어 일정온도(700-1100℃)를 유지할수가 있게 되는 것이다.On the other hand, when the internal temperature of the incinerator 1 continues to rise and reaches a constant temperature (900-1200 ° C.), the pressure pump 6 installed in the slurry hopper 5 by the action of an unillustrated temperature sensor installed in the incinerator 1 Since the operation is to spray the slurry into the incinerator, the internal temperature of the incinerator 1 is lowered to maintain a constant temperature (700-1100 ℃).

즉, 수분이 증발된 액상폐기물의 찌꺼기인 슬러리가 폐수증발기(7)하부로 침전되어 슬러리호퍼(5)에 집결된 상태에서 압송펌프(6)가 작동하게 되면 슬러리공급관(9)을 통하여 그 출구에 설치된 분사노즐(도시생략)에 의해 소각로(1)의 1, 2차 연소실에 가압분사 되게된다.That is, when the pressure pump 6 is operated while the slurry, which is the residue of the liquid waste vaporized with water, is precipitated under the wastewater evaporator 7 and collected in the slurry hopper 5, the slurry feed pipe 9 exits the slurry. The injection nozzles (not shown) installed in the pressure injection spray in the primary and secondary combustion chambers of the incinerator 1.

그러면 순간적으로 연소화염을 소화시키는 작용을 함과 동시에 슬러리의 재연소가 지속적으로 이루어지면서 결국 소각로(1) 내부온도를 약 900정도로 유지시키면서 산업폐기물을 소각 처리할수가 있게 되는 것이다.Then, while simultaneously acting to extinguish the combustion flame, the re-burning of the slurry is continuously made, and eventually the industrial waste can be incinerated while maintaining the temperature inside the incinerator (1) at about 900.

이와같이 본 고안은 기존의 가연성 폐기물 처리장치를 응용하여 가연성 폐기물의 처리는 물론 액상폐기물까지 한꺼번에 소각처리할수있는 장치를 제공함으로써 액상 폐기물에 의한 환경오염 문제를 해소할수가 있는것이며, 가연성(고형)폐기물의 연소가스를 이용하여 액상폐기물에 포함된 수분을 증발 분리토록 함으로써 연료절감 효과를 얻을수 있으며, 또한 기존의 폐기물 소각로에 냉각장치를 설치하지 않아도 되는등의 일석이조의 효과가 기대되는 신규의 고안인 것이다.As such, the present invention can solve the environmental pollution problem caused by liquid waste by providing a device capable of treating flammable waste as well as liquid waste at the same time by applying the existing flammable waste treatment device. By using the combustion gas to evaporate and separate the water contained in the liquid waste, it is possible to obtain a fuel savings effect, and it is a new design that is expected to have the effect of two-season tank, such as no need to install a cooling device in the existing waste incinerator.
