Description

열 안정화 공법을 이용하여 음식물쓰레기 및 유기물 쓰레기를 비료화하는 비료제조시스템Fertilizer manufacturing system to fertilize food waste and organic waste using heat stabilization method
본 발명은 음식물쓰레기 및 유기물 쓰레기와 생석회를 1차 혼합한 후 두드림과 교반을 동시에 이루어지도록 함으로서 생석회의 크기를 잘게 깨트려 음식물쓰레기 및 유기물 쓰레기의 수분과의 수화반응속도가 빠르게 일어나도록 하여 무기물인 생석회의 사용량을 현저히 저감되도록 하여 비료 생산의 생산성을 극대화하도록 한 열 안정화 공법을 이용하여 음식물쓰레기 및 유기물 쓰레기를 비료화하는 비료제조시스템에 관한 것이다.The present invention is to mix the food waste and organic waste and quicklime first, and then tapping and stirring at the same time to break the size of quicklime finely so that the hydration reaction rate of the food waste and organic waste with moisture occurs quickly The present invention relates to a fertilizer manufacturing system for fertilizing food waste and organic waste using a thermal stabilization method to maximize the productivity of fertilizer production by significantly reducing the amount of quicklime used.
통상적으로, 음식물쓰레기는 수분 함량이 80~85%로서 쉽게 부패되어 악취와 오수가 발생하므로 분리 수거 및 운반이 어려우며, 매립시 다량의 침출수가 흘러나와 토양 및 지하수를 오염시키는 등 2차적인 환경 오염을 유발한다. 이와 같은 음식물쓰레기를 처리하기 위한 다양한 방법이 시도되어 왔는데 그중 대표적인 것이 호기성 미생물을 이용한 퇴비화 방법이다.Generally, food waste is easily decayed due to 80 ~ 85% of moisture content, so it is difficult to separate and transport because of bad smell and sewage. Secondary environmental pollution such as large amount of leachate flows out during landfill, contaminating soil and groundwater. Cause. Various methods for treating such food waste have been attempted, a representative one of which is a composting method using aerobic microorganisms.
이 방법은 호기성 미생물에 의해 유기물질을 분해하여 무기물질과 같은 부산물과 CO2와 NH3 등으로 변환시켜 안정화시키는 방법으로서, 호기성 상태의 발효기 내에서 투입된 미생물 발효제에 의해 음식물쓰레기 내의 유기물질이 안정된 부식토로 전환되며, 병원균은 지속적인 발효열에 의해 사멸되고 최종적으로 흙냄새가 나는 짙은 갈색의 퇴비가 되는 것이다. This method decomposes organic materials by aerobic microorganisms and converts them into by-products such as inorganic materials and CO2 and NH3.These methods stabilize microorganisms in food wastes by using microbial fermenters in aerobic fermenters. The pathogen is killed by continuous fermentation heat and finally becomes a dark brown compost with a odor.
그러나, 상술한 바와 같은 호기성 미생물을 이용한 음식물쓰레기 처리 방법은 퇴비가 완성되기 전까지 몇 개월 정도의 기간이 소요되는 등 시간 소요가 많으며, 선별 시설, 혼합 및 발효 시설, 불순물 제거 시설, 숙성 시설 등 많은 종류의 시설이 요구되어 경제성이 떨어진다는 문제점이 있었다. However, the method of treating food waste using aerobic microorganisms as described above takes a few months before composting is completed, and a lot of time is required, such as a sorting facility, a mixing and fermentation facility, an impurity removal facility, and a aging facility. There is a problem that the economic efficiency is low because a kind of facilities are required.
상기와 같은 문제점을 해결하기 위하여 종래에는 짧은 기간 내에 간단한 시설만으로 음식물쓰레기를 비료화 할 수 있는 생석회를 이용한 음식물쓰레기 처리 방법이 제안된바 있다. In order to solve the above problems, conventionally, a food waste treatment method using quicklime that can fertilize food waste with a simple facility within a short period of time has been proposed.
상기한 생석회를 교반 스크류를 구비한 반응조 내 투입하여 생석회와 음식물쓰레기 및 유기물 쓰레기 등에서 생성되는 수분간의 수화 반응 및 가수분해에 의해 음식물쓰레기 내의 수분과 염분을 제거하고 이때 만들어진 악취가 나는 가스는 여과기를 통해 외부로 배출함으로써 비료를 제조하였다. The quicklime is introduced into a reaction tank equipped with a stirring screw to remove moisture and salts in the food waste by hydration reaction and hydrolysis of quicklime, food waste and organic waste for several minutes. Fertilizer was prepared by discharged through the outside.
생석회를 교반 스크류가 구비된 반응조에 음식물쓰레기 및 유기물 쓰레기 등과 같이 투입하여 반응시키는 종래 음식물쓰레기 및 유기물 쓰레기를 비료화하는 비료제조장치는 다음과 같은 문제가 있다. The conventional fertilizer manufacturing apparatus for fertilizing food waste and organic waste by adding quicklime to a reaction tank equipped with a stirring screw, such as food waste and organic waste, has the following problems.
첫째, 생석회의 크기가 크거나 작게 형성된 생석회를 그대로 반응조 내부로 공급함으로 너무 비대한 생석회는 표면에서만 반응이 발생 되어 생석회를 과대하게 사용하는 문제점이 있으며,  First, by supplying the quicklime, which is formed large or small, into the reactor as it is, the excessively large quicklime reacts only on the surface, causing excessive use of quicklime.
둘째, 이로 인해 유기물보다 무기물의 함유량이 과다하여 비료로서의 효과 및 효능이 저감되는 문제점이 있으며, 따라서 토지의 형질이 변화되는 문제점도 있다. Secondly, due to this, there is a problem in that the content of the inorganic material is higher than the organic material, so that the effect and efficacy as a fertilizer is reduced, and therefore, the characteristics of the land are changed.
셋째, 생석회를 교반 스크류가 구비된 반응조에 음식물쓰레기 및 유기물 쓰레기 등과 같이 투입하여 반응시킴으로서 교반 스크류를 중심으로 보았을 때 외측 부분은 너무 반응속도가 빨라 유기물이 너무 건조하게 되고, 교반 스크류와 가까운 내측 부분은 반응속도가 늦어 마치 진흙과 같은 상태가 발생하데 되는 문제점으로 비료의 생산성 저하를 가져오게 되는 문제점이 있다. Third, the quicklime is reacted by adding food waste and organic waste to a reaction tank equipped with a stirring screw, and when the center of the stirring screw is viewed, the outer portion is too fast to react and the organic material is too dry, and the inner portion close to the stirring screw. Due to the slow reaction rate, mud-like conditions may occur, resulting in a decrease in fertilizer productivity.
본 발명은 상기한 종래 문제점을 감안하여 안출한 것으로서 본 발명의 목적은 음식물쓰레기 및 유기물 쓰레기와 생석회를 전반응조에서 1차 혼합한 후 두드림과 교반을 동시에 이루어지도록 함으로서 생석회의 크기를 잘게 깨트려 음식물쓰레기 및 유기물 쓰레기의 수분과 1차로 반응시킨 후 주반응조에서 수화반응을 2차로 일으켜 음식물쓰레기 및 유기물 쓰레기의 수화반응 속도가 빠르게 일어나도록 하여 무기물인 생석회의 사용량을 현저히 저감되도록 하여 비료 생산의 생산성을 극대화하도록 함과, 악취가 함유된 가스를 자외선 영역에서 활성화되는 광촉매를 사용하는 여과수단을 이용하여 가스를 정화/여과하여 일부는 대기중으로 배출시키고 일부는 다시 주반응기로 환원시켜 반응물의 건조 및 안정화를 유도하도록 한 열 안정화 공법을 이용하여 음식물쓰레기 및 유기물 쓰레기를 비료화하는 비료제조시스템을 제공하도록 함에 있다.The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to break the size of quicklime finely by simultaneously tapping and stirring after mixing food waste and organic waste and quicklime in a pre-reactor.

Maximizes and purifies / filters the gas containing the malodor by using a photocatalyst that is activated in the ultraviolet region, partly to be discharged to the atmosphere, and partly to the main reactor to dry and stabilize the reactant. Using thermal stabilization It is to provide a fertilizer manufacturing system to fertilize food waste and organic waste.

한편 상기 주반응조(300)에는 반응된 음식물쓰레기 및 유기물 쓰레기와 생석회를 일정한 형태가 되도록 성형하는 펠렛수단(700)을 더 설치하여 사용할 수도 있다.On the other hand, the main reaction tank 300 may be used by further installing a pellet means 700 for molding the reacted food waste and organic waste and quicklime to a certain form.
한편 첨부도면 도 3에 도시된 바와 같이 건조수단(800)을 더 설치하여 주반응조(300)에서 배출되는 반응물을 건조시켜 보관이 용이하게 할 수도 있다. 이때 도면에는 표시되어 있지는 않으나 상기 건조수단(800)의 후단에 펠렛수단(700)을 연결 설치하여 사용할 수 있다.Meanwhile, as shown in FIG. 3, a drying unit 800 may be further installed to dry the reactants discharged from the main reaction tank 300 to facilitate storage. In this case, although not shown in the drawing, the pellet means 700 may be connected and installed at the rear end of the drying means 800.
상기와 같은 구조를 갖는 본 발명의 음식물쓰레기 및 유기물 쓰레기를 비료화하는 비료제조시스템의 작동을 설명하면 첨부도면 도 1에 도시된 바와 같이 음식물쓰레기 및 유기물 쓰레기와 생석회를 전반응조(100)에 투입한다. Referring to the operation of the fertilizer manufacturing system for fertilizing food waste and organic waste of the present invention having the structure as described above, as shown in Figure 1 attached to the food waste and organic waste and quicklime in the pre-reactor 100. .
예컨데 음식물쓰레기 및 유기물 쓰레기 등과 생석회를 투입할 수 있는 도어를 사용하여 하우징 내측에 공급한 후 구동모터를 작동시키면 상기 구동모터와 연결되어 회전하는 회전자도 동시에 회전됨과 상기 회전자에 매달려 자유로이 요동할 수 있는 자유운동절단부재가 회전하면서 자유로이 요동치게 되면서 음식물쓰레기 및 유기물 쓰레기 등을 두드려 잘게 부수면서 교반을 하게 된다.For example, when the inside of the housing is supplied using a door into which food waste, organic waste, etc. can be added quicklime, and the driving motor is operated, the rotating rotor connected to the driving motor rotates at the same time and freely swings on the rotor. As the free motion cutting member can swing freely while rotating, the food waste and organic waste can be knocked and crushed while stirring.
이때 상기 부피가 비대한 생석회는 자유운동절단부재와 부딪히는 횟수가 많게 됨으로 붙딛혀서 그 충격으로 잘게 부수어지게 되며 부수워진 생석회와 음식물쓰레기 및 유기물 쓰레기가 자유운동절단부재가 부착 설치된 회전자의 회전에 의해 교반이 이루어진다. At this time, the bulky quicklime is more frequently hit by the free motion cutting member, so it is crushed finely by its impact, and the broken quicklime, food waste and organic waste are rotated by the rotation of the rotor installed with the free motion cutting member. Stirring is done.
따라서 상기 전반응조(100)에 투입된 음식물쓰레기 및 유기물 쓰레기 등과 생석회는 수화반응을 1차로 일으키게 되며 소정시간 수화반응을 일으킨 생석회와 음식물쓰레기 및 유기물 쓰레기는 배출구를 통해 외부로 배출되어 이송수단(200)의 작동으로 주반응조에 투입하면 상기 주반응조(300)에는 구동모터와 연결되어 회전하는 교반 스크류가 설치되어 음식물쓰레기 및 유기물 쓰레기 등과 생석회는 수화반응을 촉진시켜며 골고루 교반이 이루어지도록 한다.Therefore, the food waste and organic waste and the quicklime which are put into the pre-reaction tank 100 cause the hydration reaction primarily, and the quicklime and the food waste and the organic waste which caused the hydration reaction for a predetermined time are discharged to the outside through the discharge port and the transfer means 200. Into the main reaction tank by the operation of the main reaction tank (300) is connected to the drive motor is installed to rotate the stirring screw to facilitate the hydration reaction of food waste and organic waste, such as quicklime to ensure a uniform stirring.
이때 상기 음식물쓰레기 및 유기물 쓰레기와 생석회의 반응시 가스가 발생되는데 상기 반응시 발생되는 가스는 여과수단(400)으로 이송되어 정화 및 여과된다. At this time, gas is generated during the reaction of the food waste and organic waste and quicklime, and the gas generated during the reaction is transferred to the filtering means 400 to be purified and filtered.
상기 주반응조(300) 내부에서 발생된 가스가 여과수단(400)으로 빠르게 이동될 수 있도록 주반응조(300)와 여과수단(400) 사이에 송풍장치(600)를 설치하면 가스를 강제로 여과수단(400) 쪽으로 이동시킬 수 있게 된다.When the blower device 600 is installed between the main reaction tank 300 and the filtering means 400 so that the gas generated in the main reaction tank 300 can be quickly moved to the filtering means 400, the gas is forced to filter means. To 400 side.
한편 상기 여과수단(400)은 주반응조(300)에서 발생된 악취 및 오염된 가스를 정화/여과하게 된다. 또한 자외선 영역에서 활성화되는 광촉매재에 의하여 Co2 가스가 생성된다.Meanwhile, the filtration means 400 purifies / filters malodorous and contaminated gas generated in the main reactor 300. In addition, Co 2 gas is generated by the photocatalyst activated in the ultraviolet region.
상기 여과수단(400)에 의해 정화/여과한 가스의 일부는 대기중으로 배출시키고 일부는 다시 재순환파이프수단(500)에 의해 주반응기(300)로 재순환 공급되어 반응물의 건조 및 안정화를 유도하게 된다.Part of the gas purified / filtered by the filtration means 400 is discharged to the atmosphere and part is recycled to the main reactor 300 by the recycle pipe means 500 to induce drying and stabilization of the reactants.
이때 상기 주반응조의 내측으로 입설되도록 연결되는 재순환파이프수단(500)에는 노즐(510)이 설치되어 있어 자연압에 의해 Co2 가스가 분무되며, 상기 Co2 가스가 재순환파이프수단(500)에 의해 주반응조(300)로 재순환 공급되면 주반응조(300) 내부에서는 Ca(OH)2 + Co2 → CaCo3 ≒ 17.23kcal/mol의 반응열을 발생하게 됨으로 주반응조 내부 온도를 상승시키게 되어 보다 빠르게 반응이 일어나도록 환경을 조성하게 된다. 또한 상기 반응이 일어날 때 여기서 생성된 H2O는 Co2 가스와 반응하여 H+를 생성시켜 pH를 감소시키는 순환반응을 일으킨다.At this time, the nozzle 510 is installed in the recirculation pipe means 500 connected to the inside of the main reactor to spray Co 2 gas by natural pressure, and the Co 2 gas is recirculated by the recirculation pipe means 500. When recirculated and supplied to the main reactor 300, the reaction heat of Ca (OH) 2 + Co 2 → CaCo 3 ≒ 17.23 kcal / mol is generated inside the main reactor 300, thereby increasing the temperature of the main reactor and causing a faster reaction. Environment will be created. In addition, when the reaction occurs, the H 2 O generated here reacts with Co 2 gas to generate a H + to cause a cyclic reaction to decrease the pH.
따라서 상기 주반응조(300)에서 수화반응을 2차로 다시 일으켜 음식물쓰레기 및 유기물 쓰레기의 수화반응 속도가 빠르게 일어나도록 하여 무기물인 생석회의 사용량을 현저히 저감되도록 하여 비료 생산의 생산성을 극대화하도록 함과, 악취가 함유된 가스를 자외선 영역에서 활성화되는 광촉매를 사용하는 여과수단(400)을 이용하여 가스를 정화/여과하여 일부는 대기중으로 배출시키고 일부는 다시 주반응기(300)로 환원시켜 반응물의 건조 및 주반응조(300)의 내부환경(온도/압력)을 조절하여 비료제조시스템의 안정화를 유도할 수 있는 등의 효과를 얻게 된다. Therefore, the hydration reaction in the main reaction tank 300 again to cause the hydration reaction rate of food waste and organic waste to occur quickly to significantly reduce the use of mineral quicklime to maximize the productivity of fertilizer production and odor Gas is purged / filtered using a filter means 400 using a photocatalyst activated in the ultraviolet region, and some are discharged to the atmosphere, and some are reduced to the main reactor 300 again to dry and react the reactants. By controlling the internal environment (temperature / pressure) of the reaction tank 300, it is possible to induce the stabilization of the fertilizer manufacturing system.
상기에서와 같이 주반응조(300)에서 반응이 완료된 상태로 배출시켜 흙과 같은 상태의 분말형태로 사용할 수도 있으나 As described above, by discharging the reaction in the state in which the reaction is completed in the main reaction tank 300 may be used in the form of powder in the same state as the soil
일정한 형태가 되도록 성형하는 펠렛수단(700)을 더 연결 설치하여 과립상태로 제조하여 사용할 수도 있다. 상기 펠렛수단(700)을 이용하여 반응물을 펠렛형태로 제조하면 사용 및 보관과 이동 등에서 용이한 이점이 있기 때문이다.Pellet means (700) to be molded to form a predetermined form may be further installed and used in granular form. This is because when the reactant is manufactured in pellet form using the pellet means 700, there is an easy advantage in use, storage and movement.
