본 발명은 음식물처리장에서 발생하는 협잡물을 고형연료로 처리하는 방법에 관한 것으로, 보다 상세하게는 음식물쓰레기를 처리할 때 원물처리 후 퇴비화를 위한 퇴비장에서 발생하는 협잡물 속에 포함된 비닐류를 별도로 선별 수거하여 고형연료로 연료화시킴으로써 에너지재생산성을 높이도록 개선된 음식물처리장에서 발생하는 협잡물을 고형연료로 처리하는 방법에 관한 것이다.The present invention relates to a method of treating impurities generated in a food processing plant with solid fuel, and more particularly, when processing food waste, vinyls included in impurities generated in a composting field for composting after raw material treatment are separately selectively collected and collected. It relates to a method of treating impurities generated in a food processing plant improved to increase energy regeneration by converting into solid fuel into solid fuel.

음식물 쓰레기 비닐은 음식물 찌꺼기를 담아 버리는 용도로 사용되며, 특히 우리나라에서는 음식물 찌꺼기를 버릴 때 음식물 쓰레기 비닐의 사용을 의무화하고 있다. Food waste vinyl is used to contain and discard food waste, and in particular, in Korea, the use of food waste plastic is obligatory when throwing away food waste.

그러나, 음식물 찌꺼기를 처리하는 과정에서 음식물 찌꺼기만이 걸러져 가축의 사료나 비료로 사용될 뿐, 음식물 쓰레기 비닐은 다른 협잡물과 함께 버려지는 것이 작금의 실정이다.However, in the process of processing the food waste, only the food waste is filtered and used as animal feed or fertilizer, and the food waste vinyl is thrown away together with other impurities.

통상, 음식물 쓰레기는 원물처리장에서 파쇄되면서 1차 처리되어 대부분의 ㅂ닐들은 수거된 후 세척, 건조된 다음에 소각장으로 보내져 소각처리된다.In general, food waste is first treated while being crushed at a raw material treatment plant, and most of the waste is collected, washed, dried, and then sent to an incineration plant to be incinerated.

그리고, 원물처리장에서 처리된 처리물은 퇴비장으로 반송되어 발효처리됨으로써 비료나 퇴비로 재활용되게 된다.In addition, the treated material processed in the raw material treatment plant is returned to the composting plant and subjected to fermentation treatment, whereby it is recycled as fertilizer or compost.

이 과정에서도 상당한 양의 비닐이 선별되는데, 이때에도 수거된 비닐 역시 소각장으로 보내져 소각처리되게 된다.In this process, a significant amount of vinyl is sorted out, and even at this time, the collected vinyl is also sent to an incineration plant to be incinerated.

그런데, 발효장의 경우 발효되는 과정에서 상당히 높은 발효열 때문에 대부분의 비닐이 함수율 4% 이하로 바짝 마른 상태, 즉 완전히 건조된 상태를 유지함에도 불구하고 별도의 처리비용을 지불하면서까지 소각해야 하는 불편함, 비용낭비, 재생가능한 자원의 낭비 등이 내재되어 있다.However, in the case of fermentation, due to the fairly high heat of fermentation during fermentation, most of the vinyl is dry with a water content of 4% or less, that is, despite maintaining a completely dry state, the inconvenience of having to incinerate while paying a separate treatment cost, Waste of money and waste of renewable resources are inherent.

이하에서는, 첨부도면을 참고하여 본 발명에 따른 바람직한 실시예를 보다 상세하게 설명하기로 한다.Hereinafter, preferred embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.

본 발명 설명에 앞서, 이하의 특정한 구조 내지 기능적 설명들은 단지 본 발명의 개념에 따른 실시예를 설명하기 위한 목적으로 예시된 것으로, 본 발명의 개념에 따른 실시예들은 다양한 형태로 실시될 수 있으며, 본 명세서에 설명된 실시예들에 한정되는 것으로 해석되어서는 아니된다.Prior to the description of the present invention, the following specific structural or functional descriptions are only exemplified for the purpose of explaining embodiments according to the concept of the present invention, and embodiments according to the concept of the present invention may be implemented in various forms, It should not be construed as limited to the embodiments described herein.

도 1에 도시된 바와 같이, 본 발명에 따른 음식물처리장에서 발생하는 협잡물을 고형연료로 처리하는 방법은 음식물쓰레기 봉투째 수거된 음식물쓰레기를 파쇄한 후 협잡물을 1차 선별하는 원물처리단계, 처리된 원물을 수거하여 퇴비장에 넣고 1,2차에 걸쳐 발효시키는 퇴비화처리단계, 발효시 발생되는 발효열에 의해 건조된 발효물로부터 비닐을 분리하는 비닐선별단계를 포함하는 처리방법에 적용된다.As shown in FIG. 1, the method of treating impurities generated in a food processing plant with solid fuel according to the present invention includes a raw material processing step of first sorting impurities after crushing food waste collected in a food waste bag, processed It is applied to a treatment method including a composting step of collecting raw materials and putting them in a composting field for first and second fermentation, and a vinyl sorting step of separating vinyl from dried fermented material by the heat of fermentation generated during fermentation.

이때, 원물처리단계는 통상적으로 이루어지는 1차 수거업체의 원물처리장에서 진행하며, 퇴비화처리단계는 발효시설을 갖춘 2차 처리업체의 퇴비장에서 이루어진다.At this time, the raw material treatment step is normally performed at the raw material treatment plant of the primary collection company, and the composting treatment step is performed at the compost field of the secondary treatment company equipped with fermentation facilities.

이 경우, 원물처리장에서 1차로 다량의 비닐을 분리 선별하고 있지만, 퇴비장으로 이동했을 때에도 여전히 선별되지 못한 많은 양의 비닐이 포함되어 있다.In this case, although a large amount of vinyl is first separated and sorted at the raw material treatment plant, a large amount of vinyl that has not been sorted is still included even when it is moved to the compost field.

아울러, 퇴비장에서는 1,2차에 걸쳐 원물이 발효되게 되면 발효율이 거의 70-80℃에 육박하기 때문에 발효 완료시점에서는 거의 대부분 완전에 가깝게 건조되게 된다.In addition, in the composting field, when raw materials are fermented through the 1st and 2nd stages, the fermentation rate approaches almost 70-80℃, so most of them are almost completely dried at the point of completion of fermentation.

그리고, 발효가 완료된 상태에서 비닐선별단계를 통해 비닐을 포함한 협잡물이 최종 선별되고, 그 중에서도 공지된 칼귀 방식을 이용하여 비닐만 따로 선별할 수 있게 된다.And, in the state that fermentation is completed, impurities including vinyl are finally sorted through the vinyl sorting step, and among them, only vinyl can be sorted separately using a known knife method.

여기에서, 최종 선별된 비닐은 수분함수율이 4% 이하로 거의 완전하게 건조된 상태를 유지한다.Here, the finally selected vinyl maintains an almost completely dried state with a moisture content of 4% or less.

때문에, 조금만 타격해도 붙은 먼지들이 쉽고 빠르게 털어질 수 있다.Therefore, even with a slight blow, the adhering dust can be easily and quickly brushed off.

본 발명에서는 이러한 특성을 이용하여, 풍타단계를 더 수행한다.In the present invention, using this characteristic, the wind-tapping step is further performed.

상기 풍타단계란 수거된 비닐을 풍타챔버에 넣고, 바람을 펄싱하여 바람으로 비닐을 타격함으로써 비닐에 붙은 이물질을 완전히 분리하는 단계이다.The wind blowing step is a step of completely separating the foreign substances attached to the vinyl by putting the collected vinyl into the wind blowing chamber and pulsing wind to blow the vinyl with the wind.

이때, 에어 펄싱은 고압의 에어를 0.1-0.2초 간격으로 단속적으로 연속 타격하며, 풍타챔버의 바닥면은 격자형 배출구를 가지고 있어 분리된 이물질은 하부로 낙하하면서 자연 분리되게 된다.At this time, the air pulsing continuously strikes high-pressure air intermittently at intervals of 0.1-0.2 seconds, and the bottom surface of the wind blower chamber has a lattice-shaped outlet, so that the separated foreign substances are naturally separated while falling to the bottom.

그리고, 풍타단계 후 이물질이 제거된 비닐은 용융로로 투입되어 가열 용융되는 가열용융단계를 거친다.Then, after the blowing step, the vinyl from which foreign substances are removed is put into a melting furnace and undergoes a heating and melting step in which it is heated and melted.

이렇게 하여, 가열용융된 비닐용융물은 압출기로 투입된 후 펠릿으로 압출되는 펠릿압출단계를 거쳐 고형연료로 변하게 된다.In this way, the heated and melted vinyl melt is changed into solid fuel through a pellet extrusion step in which it is introduced into an extruder and then extruded into pellets.

한편, 비닐용융물을 압출하기 전에 비닐용융물에 포함된 흙 등의 불연물과 같은 이물질을 한번 더 걸러내어 고형연료의 순도를 높일 수 있도록 도 2와 같은 필터장치(100)를 거치도록 할 수 있다.On the other hand, before extruding the vinyl melt, it may be passed through the filter device 100 as shown in FIG. 2 to increase the purity of the solid fuel by filtering out foreign substances such as incombustibles such as soil included in the vinyl melt once more.

즉, 필터장치(100)는 용융로의 배출단과 압출기의 투입단 사이에 배치될 수 있다.That is, the filter device 100 may be disposed between the discharge end of the melting furnace and the input end of the extruder.

이러한 필터장치(100)는 2개의 필터박스(110)와, 상기 필터박스(110)에 내장되는 박스형상의 상부체(120) 및 하부체(130)를 포함한다.This filter device 100 includes two filter boxes 110, and a box-shaped upper body 120 and lower body 130 built into the filter box 110.

이때, 상부체(120)는 필터박스(110)의 내부에 고정되고, 상단면에는 인렛관(122)이 배관된다.At this time, the upper body 120 is fixed inside the filter box 110, and the inlet pipe 122 is piped to the upper surface.

상기 인렛관(122)은 도시와 같이 각각의 필터박스(110)에 연결되는 것이므로 2개 구비되고, 이들은 용융로의 배출단과 연결된 용융물공급관(150)에 연결되며, 이들이 연결되는 지점에는 유로전환밸브(140)가 설치되어 공급되는 용융물의 방향을 전환할 수 있도록 구비된다.Since the inlet pipe 122 is connected to each filter box 110 as shown in the figure, two are provided, and they are connected to the melt supply pipe 150 connected to the discharge end of the melting furnace, and at the point where they are connected, a flow path conversion valve ( 140) is installed to change the direction of the supplied melt.

또한, 상부체(120)의 하단은 삼각형상으로 뾰족하게 돌출되며, 돌출된 부분에는 다수의 배출구멍이 형성되어 용융물이 흘러내릴 수 있도록 구성된다.In addition, the lower end of the upper body 120 protrudes sharply in a triangular shape, and a plurality of discharge holes are formed in the protruding portion so that the melt can flow down.

아울러, 하부체(130)의 상단면은 상기 상부체(120)의 하단에 대응되는 형상을 갖고, 상단면 자체에 다수의 필터망(132)이 고정된 구조를 갖는다.In addition, the upper surface of the lower body 130 has a shape corresponding to the lower end of the upper body 120, and has a structure in which a plurality of filter nets 132 are fixed to the upper surface itself.

그리고, 하단면 중앙에는 배출구(134)가 형성되고, 상기 배출구(134)에는 아웃렛관(136)이 연결되어 흘러내린 용융물을 압출기의 투입단으로 인입시킬 수 있게 설치된다.In addition, an outlet 134 is formed at the center of the bottom surface, and an outlet pipe 136 is connected to the outlet 134 so that the melted material flowing down can be drawn into the input end of the extruder.

특히, 상기 하부체(130)의 하단면 양측에는 볼(BAL)이 회전가능하게 조립되고, 상기 필터박스(110)의 내부 바닥면에는 상기 볼(BAL)이 안착될 수 있는 볼홈(HOM)이 형성된다.In particular, balls (BAL) are rotatably assembled on both sides of the bottom surface of the lower body 130, and ball grooves (HOM) in which the balls (BAL) can be seated are formed on the inner bottom surface of the filter box 110. is formed

뿐만 아니라, 상기 하부체(130)는 내장될 뿐 고정되는 것이 아니므로 움직일 수 있으며, 상기 필터박스(110)의 일측에는 하부에 턱이없는 도어(DR)가 설치된다.In addition, since the lower body 130 is built-in and not fixed, it is movable, and a jawless door DR is installed on one side of the filter box 110.

따라서, 필터링과정에서 일측 필터박스(110)의 필터망(132)이 막히면 유로전환밸브(140)를 전환하여 다른쪽 필터박스(110)로 용융물의 공급이 방향전환되게 하고, 도어(DR)를 연 후 막히 필터망(132)측 하부체(130)를 당겨 빼내면 쉽게 분리 취출할 수 있게 된다.Therefore, in the filtering process, when the filter net 132 of the filter box 110 on one side is clogged, the flow path conversion valve 140 is switched to change the direction of supply of the molten water to the filter box 110 on the other side, and the door DR is closed. After opening, if the lower body 130 on the side of the filter net 132 is pulled out, it can be easily separated and taken out.

그런 후에 필터망(132)을 청소하고 다시 세팅하면 용융물의 공급을 중단하지 않고 연속적으로 공급하면서 필터 청소는 주기적으로 자연스럽게 수행할 수 있게 되어 효율적인 처리가 가능하게 된다.After that, if the filter net 132 is cleaned and set again, filter cleaning can be performed periodically and naturally while continuously supplying the molten material without stopping the supply, so that efficient treatment is possible.

특히, 하부체(130)의 바닥면에는 상기 배출구(134)를 향해 경사진 경사배출가이드(BL)가 더 형성될 수 있다.In particular, an inclined discharge guide BL inclined toward the outlet 134 may be further formed on the bottom surface of the lower body 130 .
