Abstract
일반 가정, 음식을 제공하거나 판매하는 집단 급식소, 또는 음식점에서 발생하는 음식물 폐기물은 그 폐기물의 특성상 먼저 자가분해에 의해 가수분해가 일어나고 신속히 부패가 진행되어 침출수가 발생하며, 그 과정에서 유기산 등이 생성되면서 악취가 발생하여 사람들에게 혐오스럽고 귀찮은 폐기물로 인식되어왔다. 그래서 주부들이나 식품 관계자들에게 이 음식물 폐기물의 처리는 커다란 부담이 되고 있을 뿐만 아니라 이를 처리할 의무가 있는 지자체에서도 많은 비용을 지불하여도 만족할 만한 처리시설도 없으며, 뚜렷한 대안도 아직 없는 실정이다.Food wastes generated in general homes, group catering establishments or restaurants that provide or sell food are hydrolyzed by self-decomposition first, and rapidly decay, and leachate is generated, and organic acids are generated in the process. As a result, bad smells have occurred and have been recognized as abomination and annoying waste to people. So for housewives and food officials, the disposal of this food waste is not only a huge burden, but even the municipalities that are obliged to dispose of it do not have a satisfactory treatment facility and there is no clear alternative yet.
일반적으로 폐기물 처리과정을 살펴볼 때, 발생원에서 바로 처리하던 악취 등의 문제가 적고, 운반의 필요가 없어 처리가 쉬워진다. 그래서 본 발명은 음식물 폐기물을 그 발생원인 조리용 싱크대에서 바로 본 처리기로 투입하여 분쇄단계, 고형물의 분리단계, 탈수단계, 소각단계의 과정을 거치면서 처리하게 되는데 전혀 음식물 폐기물의 이동이 없어 사람들의 번거로운 수고를 끼치지 않고, 냄새도 발생하지 않으며 깨끗하게 처리하는 공정이며 콤팩트하고 자동화된 일련의 처리설비로 구성 되어 있다.In general, when looking at the waste treatment process, there are fewer problems such as odors that were directly treated at the source, and there is no need for transportation, which makes the treatment easier. Therefore, the present invention is to put the food waste directly into the processor from the cooking sink that is the source of the processing, and the process of grinding, separating the solids, dehydration, incineration of the process, there is no movement of food waste at all It is a process that does not cause troublesome labor, does not generate odors, is treated cleanly, and is composed of a series of compact and automated treatment facilities.
Description
음식물 쓰레기는 사람들이 먹고 남아 버린 음식의 쓰레기뿐만 아니라 음식을 조리하기 전의 재료의 손질 과정부터 발생하며, 조리 중에 발생하는 쓰레기, 유통기간이나 보관기간 등이 경과된 식품이나 변질된 식품, 그리고 주방기구나 조리기구, 식기의 세척 시 발생하는 오수 중의 고형물 등에서 발생한다. 보통 음식물 쓰레기의 수분함량은 80~85% 전후이며, 쓰레기 발생과 동시에 조직의 변형이 이루어지면서 자기소화효소에 의해 가수분해작용이 시작되거나 또는 산 발효 미생물의 작용으로 인한 신속한 부패의 진행으로 악취가 심하고, 침출수가 발생하여 모두가 혐오하는 쓰레기로 진행되는 특성을 가진다. 이 음식물 쓰레기는 통계에 의하면 하루에 0.1∼0.5kg 정도 발생하는 것으로 보고 되고 있으나, 개인차가 크고 소득과 주거환경 등의 생활 패턴에 따라 차이가 있을 수 있다.Food waste occurs not only from the waste of food that people eat and remain, but also from the process of cleaning the ingredients before cooking food. Or solids in sewage from cooking utensils and dishes. The water content of food waste is usually around 80 ~ 85%, and as the tissue is transformed at the same time as the waste is generated, hydrolysis is initiated by autodigesting enzymes or odor is caused by rapid decay due to the action of acid fermentation microorganisms. Severe, leachate is generated and has the property of going to waste that everyone hates. According to statistics, the food waste is reported to occur about 0.1 to 0.5kg per day, but there is a large individual difference and it may be different depending on living patterns such as income and living environment.
이 발명은 음식 쓰레기의 발생원인 주방에서 외부로 이동하지 않고 음식 쓰레기를 처리하고자 하여 음식물 쓰레기 처리의 모든 공정이 주방 안에서 이루어진다.In the present invention, all processes of food waste processing are performed in the kitchen in order to treat food waste without moving out of the kitchen, which is the source of food waste.
먼저 씽크대 배수구에 분쇄기(파쇄기)를 설치한다. 그리고 음식물 쓰레기를 씽크대 배수구에 물과 함께 투입하며 그 쓰레기를 분쇄 시킨다. 이때 스푼이나 포크 등과 같은 금속물질이나 또는 뼈와 같이 매우 단단하고 분쇄가 어려운 물질이 유입할 때에는 자동으로 동작이 멈추는 안전장치가 부착된 설비를 사용한다. 이러한 분쇄과정을 통하여 쓰레기의 부피를 줄일 뿐만 아니라 그 이후로 진행되는 공정으로의 이송과 운반을 쉽게 한다. 그리고 이 분쇄과정에서 물과 함께 흘러 주므로 악취를 제거하는 기능도 수행한다. 다음에는 분쇄기에서 분쇄된 음식물 쓰레기는 고형물 분리기에서 물(세척수)과 고형물이 분리된다. 이때 음식 쓰레기에 부착된 자유수분이 물리적인 작용에 의해 이탈하면서 부리 되는 것으로 쓰레기의 함수율은 보통 90∼85%정도까지 이른다. 그리고 이 다음 공정인 탈수공정으로 진행시켜 좀 더 강력한 기계적인 힘에 의해 쓰레기를 압축하거나 또는 외부에서 열을 가하여 한층 심화된 탈수과정을 거치면서 외부수분과 일부 내부수분의 탈수 작용으로 쓰레기의 함수율을 60∼70% 정도까지 줄이고 이후 소각공정으로 진행시킨다.First, install a shredder in the sink drain. Food waste is put into the sink drain with water to crush the waste. At this time, if a metal material such as spoon or fork, or a very hard and difficult to crush material such as bone is introduced, use a device equipped with a safety device that automatically stops operation. This crushing process not only reduces the volume of waste, but also facilitates the transport and transportation to subsequent processes. And it flows with water in this grinding process, and it also performs a function of removing odor. Next, the food waste that is crushed in the grinder is separated from the water (wash water) and the solids in the solid separator. At this time, the free moisture attached to the food waste is beaked away by the physical action, the water content of the waste is usually up to 90 ~ 85%. The next process, dehydration process, is to compress the waste by more powerful mechanical force or apply heat from the outside to further dewatering process, while dehydrating external moisture and some internal moisture to improve the water content of the waste. Reduce to 60 ~ 70% and then proceed to incineration process.
탈수공정을 통과한 쓰레기는 탈수장치의 물리적인 힘에 의해 밀려서 소각공정에 유입되며 이 소각공정에서는 가정에 일반적으로 공급되는 도시가스, 전기, 혹은 유류등의 열원에 의해 건조되면서 발화되어 소각 연소되는 공정이 이루어진다. 쓰레기의 전량 소각이 완료되면 남은 잔재물(Ash)은 일정시간 냉각과정을 거친 후 세척수 2에 의해 세척되어 본래의 하수로 내 보내어지므로 전 공정이 완료된다.Garbage that has passed through the dehydration process is pushed into the incineration process by the physical force of the dehydration system.In this incineration process, it is dried and ignited and burned by the heat source such as city gas, electricity, or oil which is generally supplied to the home The process takes place. After all the incineration of waste is completed, the remaining residue (Ash) is cooled by washing water 2 after being cooled for a certain time and sent to the original sewage so that the whole process is completed.
주방에서 발생하는 음식쓰레기를 위생적이고 신속하게 처리하며, 주방 종사자나 주부들의 일손을 덜어줄 뿐만 아니라 주방 환경을 개선시키는 설비로서Hygienic and quick disposal of food waste generated in the kitchen, as well as reducing the hands of kitchen workers and housewives, as well as improving the kitchen environment
1. 음식물 쓰레기가 발생하는 현장인 주방에서 직접 처리하므로 악취, 침출수 등 2차 오염물의 발생을 최소화하며1. It is directly processed in the kitchen where food waste is generated, thus minimizing the occurrence of secondary pollutants such as odor and leachate.
2. 음식물 쓰레기를 별도의 용기에 보관하거나 포장, 운반하는 과정 등의 귀찮고 혐오스러운 과정이 없이 위생적이고 편리하게 처리하며2. Dispose of food waste in a separate container, handle it hygienically and conveniently without any annoying and disgusting processes such as packing and transporting it.
3. 집 밖으로 내 보내는 음식물 쓰레기의 발생량을 크게 줄여 지자체의 음식물 쓰레기 처리에도 도움을 주고 범국가적인 환경보전에도 기여함.3. Significantly reduces the amount of food waste sent out of the house, helping local governments deal with food waste and contributing to national environmental preservation.
음식물 쓰레기는 처리량이나 처리대상에 따라 그 처리기술을 구별할 수 있는데, 먼저 지자체등의 공공기관이나 또는 음식물 쓰레기를 대량 발생시키는 집단 급식소등에서는 사료나 퇴비화, 그리고 지렁이 사육등 대규모 처리에 주안점을 두고 있으나, 가정집이나 소규모 음식점등은 규모가 작아 처리하는데 보통 수분을 조절하여 미생물을 활용한 자가분해를 유도하는 방식으로 일명 소멸기로 감량하는 감량장치 등이 주류를 이루고 있다.Food waste can be classified according to the amount of processing and the object of treatment. First of all, in public institutions such as local governments or group catering establishments that produce large amounts of food waste, food waste, composting, and earthworm breeding are mainly focused on large-scale processing. However, homes and small restaurants, such as small scales are usually processed to reduce the weight of the so-called extinction device in a way to induce self-degradation using microorganisms by controlling moisture.
1. 음식물 쓰레기의 제로화 달성1. Achieve zero food waste
음식물 쓰레기를 분리, 탈수, 건조, 그리고 소각의 일련의 과정을 통해 유기물을 전량 소각시켜 대기 중으로 방출하고 남은 재 등 무기물성분은 미분말화하여 수세 처리하여 하수로 배출하여 내 보내버리므로 외부로의 음식물 쓰레기 반출이 없어 쓰레기의 제로화 달성이 가능함,Organic waste is incinerated and released to the atmosphere through a series of processes such as food waste, dehydration, drying, and incineration. The remaining minerals, such as ash, are finely powdered, washed with water, discharged to the sewage, and sent out. Zero waste can be achieved because there is no waste removal
2. 전 과정이 수작업 없이 전자동으로 진행시키는 설비로 구성하여 파쇄단계에서는 물을 세척수로 흘러주면서 분쇄하여 공정의 진행을 수행하며 부수적으로 수세공정을 사용하므로 악취의 방지에도 기여함.2. The whole process consists of the equipment to proceed automatically without manual work. In the crushing step, water is flowed into the washing water and crushed to carry out the process.
