Description

열분해유 폐합성수지 효율적인 재생장치{Regenerating device of waste plastics pyrolyzing oil}Regenerating device of waste plastics pyrolyzing oil

본 발명은 폐합성수지 열분해유 재생장치에 관한 것으로서, 더욱 상세히는 각종 폐합성수지를 열분해로(=반응로)에투입하여 연소실에서 발생한 고온의 연소가스를 간접열원으로 해서 열분해되도록 하여 고부가가치의 열분해유를 추출하고, 폐기물을 연소실의 연료로 공급토록 하되, 열분해유 추출 후 액화되지 않은 일부 잔류가스 또한 연소실로 투입하여 재활용하므로 해서 별도의 잔류가스처리시설를 필요치 않도록 하여 유지비를 저렴하게 한 폐합성수지 열분해유 재생장치를 제공코자 하는 것이다.The present invention relates to a waste synthetic resin pyrolysis oil regeneration device, and more specifically, to input various waste synthetic resins into a thermal decomposition furnace (=reactor) to cause thermal decomposition of high-temperature combustion gas generated in the combustion chamber as an indirect heat source to generate high value-added pyrolysis oil. To extract and supply waste as fuel in the combustion chamber, but some residual gas that is not liquefied after the extraction of pyrolysis oil is also introduced into the combustion chamber for recycling, thereby eliminating the need for a separate residual gas treatment facility to lower maintenance costs. It is intended to provide a playback device.

일반적으로 폐합성수지의 처리는 소각이나 매립에 의존하고 있으나 소각의 경우 다이옥신(dioxin)과 같은 유해물질 이 배출되어 환경오염의 원인이 되며, 일반 유동 화격자 등의 소각로에서 소각 시 고발열량으로 소각로 부하가 높아처리량이 줄어들게 되고, 용융된 합성수지에 의한 기계부식 등의 이유로 처리비가 상승하고 있다. 매립에 의한 처리역시 매립지 부족 및 지반의 불안정화 등의 문제점으로 인하여 근자에 들어 환경오염을 줄이고 자원의 재활용 측면에서 열분해에 의한 연료유 또는 석유자원으로의 회수에 대한 기술이 기히 공지된바 있다.In general, the treatment of waste synthetic resins depends on incineration or landfill, but in the case of incineration, harmful substances such as dioxin are released, causing environmental pollution. High processing capacity is reduced, and processing costs are rising due to mechanical corrosion caused by molten synthetic resin. Due to problems such as shortage of landfill and destabilization of the ground due to the treatment by landfill, technologies for recovery of fuel oil or petroleum resources by thermal decomposition have been known in recent years to reduce environmental pollution and recycle resources.

이러한 기존의 폐합성수지 열분해유 재생장치는 환원성 분위기(=환경)를 유지하기 위해서 반응기 전체를 밀폐하는 구조로 하거나, 감압의 분위기를 유지하기 위해 연속적인 투입이 불가능하여 회분(Batch)식 운전이 될 수밖에 없는This existing waste synthetic resin pyrolysis oil regeneration device has a structure in which the entire reactor is sealed in order to maintain a reducing atmosphere (=environment), or it cannot be continuously operated to maintain an atmosphere of reduced pressure, so it can be operated in batch mode. Bound

문제점을 가지고 있어서, 이를 일소코자 본 발명자는 상기 폐합성수지 열분해유 재생장치에서 재생실로 투입되는 소재를 공기를 제거한 후 자동으로 투입할 수 있는 자동투입장치를 선 특허 출원(출원번호: 10-2001-77266) 한 바 있었다.Having a problem with this, the present inventor has filed a patent application for an automatic injection device capable of automatically injecting air after removing air from the waste synthetic resin pyrolysis oil regeneration device (application number: 10-2001- 77266) There was a bar.

그러나 상기한 자동투입장치를 기존에 적용할 시 지속적인 열분해 후 잔류물(ASH)의 배출에 관련된 부분 역시 전체공정 중 자동화부분에 관련하여 구조개선의 필요성이 대두되었으며, 또한 지속적인 열원(=폐합성수지의 열분해 시공급되는 열원)공급을 위한 장치가 필요하므로 그 구조가 복잡해지고 설치비와 유지비 등의 앙등을 가지고 오며, 또한 상기 열원을 얻기 위해 별도의 전기 또는 고가의 등유, 경유 등을 사용하므로 경제성이 떨어지는 등의 단점을 가지고 있어 상기 문 제점들을 일소할 수 있는 장치의 개발이 시급히 요구되었던 것이다.However, when applying the automatic injection device described above, the part related to the discharge of the residue (ASH) after continuous thermal decomposition also raised the need for structural improvement in relation to the automated part of the whole process, and also a continuous heat source (= waste synthetic resin). The heat source supplied during pyrolysis) requires a device for supply, so its structure becomes complicated and brings with it such as installation and maintenance costs, and also uses separate electricity or expensive kerosene, light oil, etc. to obtain the heat source, so economic efficiency is poor. There is an urgent need to develop a device capable of eliminating the above problems due to its disadvantages.

이에 본 발명에서는 상기한 바와 같은 기존 폐합성수지 열분해유 재생장치가 갖는 소재 투입상의 문제점 및 배출상의문제점과 더불어 열원공급상의 문제점들을 일소할 수 있도록 소재(=폐합성수지)를 열분해로의 가동 중에 공기를 제거한 후 자동으로 연속적인 공급이 가능하게 하면서, 열분해공정 중 열분해에 의해 남은 잔류물(ASH)의 자동무산소 배출과 폐기물을 연소시켜 얻은 열원을 지속적으로 공급할 수 있는 폐합성수지 열분해유 재생장치를 제공함에 발명의 기술적 과제를 두고 본 발명을 완성한 것이다.Accordingly, in the present invention, the material (= waste synthetic resin) is supplied with air during the operation of the pyrolysis furnace so as to eliminate the problems of material input and discharge problems of the existing waste synthetic resin pyrolysis oil regeneration device as described above, as well as problems of heat source supply.

On the upper side of the reactor (10), the condenser (50) is connected to the waste synthetic resin heat dissipation oil regeneration device (A) connected to the pipe, and the reactor (10) is a person who continuously and continuously supplies waste synthetic resin from which air has been removed. It is connected to the copper input device 11 in a closed structure, and inside is formed of a shaft and a double structure to prevent bending and sagging at high temperatures.

폐합성수지의 열분해 시 잔재물을 이송할 수 있는 이송스크류(12)가 축설치되고, 상부로는 응축기(50)와 연결되고 유압실린더(14)에 의해 개폐되는 나이프게이트밸브(15)가 형성된 유입관(13)이 밀폐구조로 구성되며, 단부의 하측으로 는 열분해가 종결된 회분(=Ash)을 공기의 유입이 없이 취출할 수 있는 자동연속ASH취출장치(60)가 일체로 형성된다.When the waste synthetic resin is thermally decomposed, a transfer screw 12 capable of transferring residues is axially installed, and an inflow pipe formed with a knife gate valve 15 connected to the condenser 50 and opened and closed by a hydraulic cylinder 14 at the top. (13) is composed of a closed structure, and an automatic continuous ASH extraction device (60) capable of taking out ash (=Ash) that has undergone thermal decomposition without inflow of air is integrally formed below the end.

이상에서 살펴본 바와 같이 본 발명에서 제공하는 폐합성수지 열분해유 재생장치(A)는 기존의 장치가 환원성 분위기(=환경)를 유지하기 위해서 반응기 전체를 밀폐하는 구조로 하거나, 감압의 분위기를 유지하기 위해 연속적인 투입이 불가능하여 회분(Batch)식 운전이 될 수밖에 없던 것과 열분해유를 얻기 위해 외부의 다른 열원 즉 유류, 전기, 가스등을 사용하던 것에 비하여 자동투입장치(11)와 반응로(10)를 밀폐식 구조로 연결 형성하여 공기의 유입이 없이 미분쇄된 폐합성수지를 열분해할 수 있고, 열원 또한 건류가스화시킨 폐기물을 사용하여 연소실(30)에서 완전연소시킨 연 소가스를 이용하므로 해서 폐합성수지를 지속적으로 공급할 수 있어 원료처리량과 제품생산량을 높이고, 열원비용이거의 들어가지 않거나 오히려 폐기물처리비를 받으면서 이용 가능하므로 해서 에너지효율성 및 자원의 재활용성과 경제성을 극대화할 수 있으며, 각종 음식폐기물의 건조나 하수종말처리장의 하수슬러지 건조 및 소각처리에 있어서도 활용되는 등 그 기대되는 효과가 다대한 발명이다.As described above, the waste synthetic resin pyrolysis oil regeneration device (A) provided in the present invention has a structure in which the entire device is sealed in order to maintain a reducing atmosphere (= environment) or to maintain an atmosphere of reduced pressure. The automatic injection device 11 and the reactor 10 were compared to those that were forced to be batch operated because continuous input was impossible and that other heat sources such as oil, electricity, gas, etc. were used to obtain pyrolysis oil. It is possible to thermally decompose pulverized waste synthetic resin without inflow of air by forming it in a closed structure, and heat source is also used for the combustion gas 30, which uses completely combusted gas from the combustion chamber 30 using waste gasified waste gas. Since it can be continuously supplied, it increases raw material throughput and product production, and heat source cost is almost zero or it can be used while receiving waste treatment cost, thereby maximizing energy efficiency, resource recycling and economic efficiency, and drying or sewage of various food wastes. The expected effect is also a great invention, such as being utilized in the treatment and treatment of incineration of sewage sludge in a terminal treatment plant.

The discharge tank 64 is formed, and the transfer pipe 65 in which the transfer screw 66 is axially installed from the lower portion of the discharge tank 64 is configured to be inclined upward.

그리고 상기 연소실(30)의 투입부에 착화버너(31)와 송풍기(32)를 일체형성하며 일측에는 재생실(20)과 밀폐연결된 연통관(33)내로 공기를 공급할 수 있는 송풍팬(34)을 설치하고, 상기 열교환기(40)는 연소실(30)로부터 발생하여 재생실(20)을 통과하며 반응로(10)를 가온하고 난 후의 연소가스를 냉각시키기 위해 물탱크(80)와 순환구조로 형성되 고, 타측으로는 연소가스를 정화시키기 위한 가스정화장치(70)가 설치된다.Then, an ignition burner 31 and a blower 32 are integrally formed at an input portion of the combustion chamber 30, and an air blower fan 34 capable of supplying air into the communication pipe 33 sealedly connected to the regeneration chamber 20 is provided on one side.

In the drawing, reference numeral 71 denotes a multicyclone, 72 an I-D fan, 73 a washing tower, and 74 a chimney.

상기와 같이 구성될 수 있는 본 발명의 폐합성수지 열분해유 재생장치(A)는 폐합성수지를 열분해로의 가동 중에 공기를 제거한 후 자동으로 연속적인 공급 및 배출이 가능하게 하면서 폐기물을 연소시켜 얻은 열원을 지속적으로 연속공급할 수 있는 것으로서, 이의 작용을 이하에 보다 구체적으로 설명하면 다음과 같다.The waste synthetic resin pyrolysis oil regeneration device (A) of the present invention, which can be configured as described above, removes air during operation of the pyrolysis furnace and automatically supplies and discharges the waste heat while burning waste. As it can be continuously supplied continuously, its action will be described in more detail below.

본 발명의 자동투입장치(11)에 의해 파쇄기와 분쇄기를 통하여 미분쇄된 폐합성수지를 반응로(10)에 공기의 유입이없이 연속적으로 투입한다. 자동투입장치(11)는 선술한 바와 같이 본 발명자가 선출원(특허출원번호: 10-2001-772 66)하였는바 자세한 언급은 생략하도록 한다.The pulverized synthetic resin finely pulverized through the crusher and the grinder by the automatic injection device 11 of the present invention is continuously introduced into the reactor 10 without introducing air. As described above, the automatic injection device 11 has been previously filed by the present inventor (Patent Application No.: 10-2001-772 66), so detailed description thereof will be omitted.

상기 반응로(10) 내부에서는 미분의 폐합성수지가 연소실(30)로부터 유입된 재생실(20)내의 완전연소가스에 의해 열 분해가스와 잔재물로 열분해 되고, 열분해 된 가스는 반응로(10) 상부의 유입관(13)으로 유입되어 일정압력 이상이Inside the reactor 10, finely divided waste synthetic resin is thermally decomposed into pyrolysis gas and remnants by completely combusted gas in the regeneration chamber 20 introduced from the combustion chamber 30, and the pyrolized gas is upper part of the reactor 10 Is introduced into the inlet pipe (13).

되면 유압실린더(14)에 의해 나이프게이트밸브(15)가 열리면서 응축기(50)내부로 유입되고, 응축기(50) 내의 열분해 가스는 물탱크(80)로부터 유입된 물에 의해 액화되면서 열분해유가 생성되며, 열분해유는 재생오일탱크(90)로 저장되고, 액화되지 않은 일부 잔류가스는 가스이송관(51)을 타고 연소실(30)로 환원되어 재자원화에 일조하며 별도의 연 소에 의한 방지시설이 필요하지 않고, 상기한 잔재물은 도 4에서와 같이 반 응로(10) 일측하부에 연결된 배출관(61) 으로 반응로(10) 내부의 이중구조로 된 이송스크류(12)에 의해 배출되고, 배출관(61)상의 상부 나이프게이트밸브(62)가 열리면서 하부로 밀착되어 일정압력 이상이 되면 상부 나이프게이트밸브(62)가 닫히고 하부의 나이프게이트밸브(63)가 열리면서 배출조(64)로 배출된다. 이때 이송스크류(12)는 각종 폐합성수지의 성분이나 각 성분의 혼합량에 따 라 rpm을 콘트롤하여 체류시간을 조절할 수 있도록 하고, 배출조(64) 안에는 물이 차있어서 배출관(61)의 단부가 대 기와 접하지 않아 반응로(10) 내부로 공기가 유입되지 않으므로 반응로(10) 내부는 공기가 없는 밀폐상태를 유지할 수 있는 것이다. 그리고 배출조(64)의 잔재물은 이송관(65)내부에 축설치된 이송스크류(66)에 의해 외부로 완전히 배 출되는 것이다.When the knife gate valve 15 is opened by the hydraulic cylinder 14 and flows into the condenser 50, the pyrolysis gas in the condenser 50 is liquefied by water introduced from the water tank 80 to generate pyrolysis oil. , Pyrolysis oil is stored in a regenerated oil tank (90), and some residual gas that has not been liquefied is reduced to the combustion chamber (30) through the gas transfer pipe (51) to help re-recycling and requires a separate prevention facility. Without, the above residue is discharged by the transfer screw 12 of the double structure inside the reaction furnace 10 to the discharge pipe 61 connected to the lower side of the reaction furnace 10 as shown in FIG. ) When the upper knife gate valve 62 on the top is in close contact with the lower portion and reaches a certain pressure or higher, the upper knife gate valve 62 is closed and the lower knife gate valve 63 is opened and discharged to the discharge tank 64. At this time, the transfer screw 12 can control the residence time by controlling the rpm according to various components of the waste synthetic resin or the amount of each component mixed, and the discharge pipe 64 is filled with water, so the end of the discharge pipe 61 is large. Since the air is not introduced into the reactor 10 because it does not come into contact with the group, the inside of the reactor 10 is able to maintain a closed state without air.
