Description

차량에 탑재된 오염토양 세척 선별장치{Contaminated soil washing sorting system loaded in the vehicle}Contaminated soil washing sorting system loaded in the vehicle}

본 발명은 차량에 탑재된 오염토양 세척 선별장치에 관한 것으로, 더욱 바람직하게는 유류 또는 석유화학 오염물질이나 각종 중금속 등이 혼합되어 있는 오염토양을 별도의 세척공장으로 이동하지 않고, 세척설비가 설치된 차량을 현장으로 이동하여 현장에서 직접 오염토양을 세척설비로 유입시킨 다음, 세척수를 고압으로 분사시키면서 오염토양의 입자간 충돌 및 마찰작용을 일으키게 하여 토양입자에 흡착된 오염물질을 제거하여 세척선별된 토양을 분리 재사용할 수 있도록 하기 위한 것이다.The present invention relates to a contaminated soil washing sorting device mounted on a vehicle, and more preferably, a washing facility is installed without moving the contaminated soil mixed with oil or petrochemical contaminants or various heavy metals to a separate washing plant. After moving the vehicle to the site, the contaminated soil is introduced into the washing facility directly, and the washing water is sprayed at high pressure to cause collisions and friction between particles of the contaminated soil, thereby removing contaminants adsorbed to the soil particles. The purpose is to separate and reuse the soil.

일반적으로 환경오염은 대기오염,수질오염,토양오염으로 구분할 수 있으며, 이들 중에서 특히 토양오염은 식량 생산에 매우 심각한 위협이 될 수 있을 뿐만 아니라 지표수는 물론 지하수 오염을 통한 식수원의 오염을 유발하기 때문에 오염된 토양은 이른 시간에 정화될 필요가 있다.In general, environmental pollution can be classified into air pollution, water pollution, and soil pollution. Among them, soil pollution can be a serious threat to food production, and it causes pollution of drinking water sources through surface water and groundwater pollution. Contaminated soil needs to be cleaned up early.

근래 국내에서 발생하는 토양오염은 주로 액상 폐기물의 무단 매립 또는 누출사고로 인하여 발생하며, 그 밖에 장기간 산업활동 과정에서 방치된 지상 적치물의 지하 확산에 의해 이루어지고, 이러한 발생요인에 의해 나타난 오염토양은 단일 종의 화합물보다는 여러 종류의 화학종에 의해서 발생되며, 대표적인 복합 오염은 유류와 중금속의 형태로써 대부분의 산업활동 지역에서 발생하고 있다.In recent years, soil pollution in Korea is mainly caused by unauthorized landfill or leakage accident of liquid waste. In addition, it is caused by underground diffusion of ground stocks left over long periods of industrial activities. It is caused by several kinds of chemical species rather than a single compound, and representative compound pollution occurs in most industrial areas in the form of oils and heavy metals.

최근 오염된 토양을 복원하기 위한 방법으로는 토양 세척,소각,고형화,안정화 및 용매추출 등과 같은 물리화학적 방법과, 토양 경작,콤포스팅(composting),바이오벤팅(bioventing),식물복원 등과 같은 생물학적 방법으로 구분될 수 있으며, 이러한 여러 방법들 중에서 비교적 쉽고 오염된 토양을 신속히 복원할 수 있는 것은 토양세척방법이다.Recently, methods for restoring contaminated soils include physicochemical methods such as soil washing, incineration, solidification, stabilization and solvent extraction, and biological methods such as soil cultivation, composting, bioventing, and plant restoration. Among these methods, the soil washing method is relatively easy and can quickly restore the polluted soil.

오염된 토양의 세척방법은 적절한 세척제를 사용하여 토양입자에 결합된 유해성 유기오염물질의 표면장력을 약화시키거나 중금속을 액상으로 변화시켜 토양입자로부터 분리시켜 처리하는 기법으로서, 광범위한 유기 및 무기오염물질을 제거할 수 있는 한편 오염물질의 종류에 관계없이 적용할 수 있는 장점이 있다.The method of washing contaminated soil is a technique to reduce the surface tension of harmful organic pollutants bound to soil particles by using an appropriate cleaning agent or to separate heavy metals into liquid phase to separate them from soil particles. On the other hand, there is an advantage that can be applied regardless of the type of contaminants.

상기에서 토양 세척방법은 현장처리법(In-situ 법)과, 현장외처리법(Ex-situ 법)으로 구분되며, 현장처리법은 오염된 토양을 굴착하지 않고 세척용액 주입정,세척용액 배출정,세척유출수 처리시설,펌프 및 계장시설,휘발물질 처리시설 등을 오염된 부지에 설치하여 처리하고자 하는 오염토양 내에 세척수를 순환시켜 오염토양을 직접 세척하는 방법으로서, 처리 시간이 길고 세척액의 회수가 어려움은 물론 이동성이 없는 단점이 있기 때문에 토양 세척방법은 주로 현장외처리법이 적용된다.Soil washing method is divided into in-situ method and ex-situ method, and in-situ treatment method does not excavate contaminated soil, does not excavate contaminated soil, wash solution discharge well, and wash. Effluent treatment facility, pump and instrumentation facility, and volatile material treatment facility are installed in the contaminated site to circulate the wash water in the contaminated soil to treat the contaminated soil directly. Of course, because of the lack of mobility, the soil washing method is mainly applied off-site treatment.

현장외처리법은 토양내 오염물질의 분포 및 토양의 물리/화학적 특성을 파악하여 처리하고자 하는 범위의 오염된 토양을 굴착한 후, 적절한 세척액을 사용하여 굴착된 오염토양을 세척장치가 있는 곳에서 세척하는 방법으로서, 최근 일반화된 토양 세척방법으로 이용된다.The off-site treatment method identifies the distribution of contaminants in the soil and the physical and chemical characteristics of the soil, excavates the contaminated soil in the range to be treated, and then cleans the excavated contaminated soil with a cleaning device using an appropriate cleaning solution. As a method of washing, it is used as a recently generalized soil washing method.

종래 토양 세척방법으로 오염된 토양을 다단계로 선별 및 세척하여 오염토양에 부착된 유류 및 중금속을 포함한 각종 오염물질을 제거하여 토양을 복원하는 기술로서, 국내 특허 제10-0534067호(오염 토양의 복원과 선별 처리를 위한 토양 세척 방법과장치)가 제안되었다.It is a technology to restore soil by removing various contaminants including oil and heavy metals attached to contaminated soil by selecting and washing soil contaminated by the conventional soil washing method in multiple stages. Domestic Patent No. 10-0534067 (Restoration of polluted soil) Soil washing methods and apparatuses for water treatment and screening) have been proposed.

상기의 선행기술은 오염토양을 건식 선별단계와, 고압 살수 선별단계를 통하여 선별한 다음, 1차 세척조에서 세척하는 동시에 오염물이 다량 함유된 부유 토양과 오염물이 소량 함유된 침적 토양으로 분리 배출한 후, 분리된 침적 토양을 2차 세척조에서 세척과 동시에 미립 토양과 과립 토양으로 분리 배출하여 과립 토양은 탈수하여 복원용 토양으로 환원하며, 미립 토양은 1차 세척조에서 배출된 부유 토양과 함께 침전, 응집 및 탈수공정을 통하여 폐기용 오염 슬러지로 만들고, 오염된 세척수는 중화시켜 재활용하는 기술이다.The prior art is to screen the contaminated soil through a dry sorting step, a high pressure sprinkling sorting step, and then washed in a primary washing tank and discharged into a floating soil containing a large amount of contaminants and a sedimented soil containing a small amount of contaminants. In addition, the sedimented soil is washed in the secondary washing tank and discharged into fine soil and granulated soil at the same time, and the granulated soil is dehydrated and reduced to restoration soil. And it is a technology to make the contaminated sludge for disposal through the dehydration process, the contaminated washing water to neutralize and recycle.

이러한 종래의 선행기술은 건식 선별기와, 고압 살수 선별기에서 입도가 큰 토양입자를 선별한 후, 1차 및 2차 세척조에서 세척공정이 수행된 다음, 세척공정에서 생성된 미립토양과 부양토양을 폐기용 오염 슬러지로 만들어 폐기하므로 폐기물의 처리비용이 과다하게 소요될 뿐만 아니라 폐기물로 인하여 제2의 환경오염을 야기하는 실정이고, 특히 미립자의 토양에 흡착된 오염물질을 효과적으로 제거하지 못하는 문제점들이 있었다.The conventional prior art is to sort the soil particles with a large particle size in the dry sorter, high pressure sprinkler, washing process in the primary and secondary washing tanks, and then discard the fine soil and flotation soil produced in the washing process Since the waste is made of wastewater sludge and disposed of, the waste disposal costs are excessive, as well as a second environmental pollution caused by the waste. In particular, there are problems in that the pollutants adsorbed in the soil of the particulates cannot be effectively removed.

본 발명은 상기와 같은 문제점을 해결하기 위하여 창출한 기술로서, 미립자의 오염토양에 흡착된 각종 오염물질을 효과적으로 세척하여 토양을 복원할 뿐만 아니라 세척공정이 연속적으로 진행되는 한편 세척설비를 차량에 탑재하여 설치하였기 때문에 오염토양이 있는 현장으로 직접 차량을 이동하여 작업할 수 있도록 함을 목적으로 한다.The present invention is a technology created to solve the above problems, to effectively clean the various contaminants adsorbed to the contaminated soil of the fine particles to restore the soil, the washing process is continuously carried out while the installation of the washing equipment on the vehicle The purpose is to allow the vehicle to be moved directly to the site with the contaminated soil.

즉, 차량에 세척설비가 설치되어 있기 때문에, 준설토와 같은 오염토양이 있는 장소라면 어디든 찾아가서 현장에서 직접 오염토양을 세척하여 복원시킬 수 있고, 또 장소가 협소한 장소에서도 오염된 토양을 간편하게 세척하여 재사용할 수 있다.In other words, since the vehicle is equipped with a washing facility, any place with contaminated soil such as dredged soil can be visited and washed by directly restoring the contaminated soil at the site.In addition, the contaminated soil can be easily washed even in a narrow place. Can be reused.

이하, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자가 본 발명을 용이하게 실시할 수 있도록 설명하기 위하여, 본 발명의 가장 바람직한 실시 예를 첨부된 도면을 참고하여 설명하기로 한다.Hereinafter, the most preferred embodiments of the present invention will be described with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention.

본 발명은 도 1에 나타내는 바와 같이, 하수관거, 우수관거, 오수관거 등의 유지관리시 발생되는 준설토는 물론 각종 오염물질이 함유된 토양에서 오염물질을 효과적으로 세척하여 깨끗한 토양으로 복원하기 위한 구성이다.As shown in FIG. 1, the present invention is configured to effectively clean contaminants from soil containing various pollutants as well as dredged soils generated during maintenance of sewage, rainwater, sewage, etc., and restore them to clean soil.

즉, 준설토와 같은 오염토양이 있는 현장으로 오염토양세척설비가 설치된 차량(100)을 이동하여 차량에 설치된 호퍼(10)로 오염토양을 투입하고, 상기 오염토양은 컨베이어벨트(20)로 이송되어 오염물질에 함유된 금속을 마그넷으로 분리하기 위한 금속분리장치(30)가 설치되어 있다.That is, moving the vehicle 100 installed with the contaminated soil washing facility to the site with contaminated soil such as dredged soil, injects the contaminated soil into the hopper 10 installed in the vehicle, and the contaminated soil is transferred to the conveyor belt 20. A metal separation device 30 for separating the metal contained in the contaminant with a magnet is installed.

상기 금속물질이 제거된 오염토양은 다시 컨베이어벨트(21)를 따라 워싱스크린장치(50)로 이송되고, 상기 워싱스크린장치(50)에서는 처리수조 저장탱크(40)에 저장된 세척수를 고압으로 오염토양에 분사시켜서 세척된 토양(90)을 선별하도록 구성되어 있다.The contaminated soil from which the metal material is removed is transferred back to the washing screen device 50 along the conveyor belt 21, and the washing screen device 50 contaminates the washing water stored in the treatment tank storage tank 40 at high pressure. It is configured to sort the washed soil 90 by spraying on.

이때 워싱스크린장치(50)는 스크린(51)(52)이 2단으로 설치되어 세척된 토양을 선별하는 구성이다. 상기 선별된 토양(90)은 대략 3mm정도의 크기이다.At this time, the washing screen device 50 is a screen 51, 52 is installed in two stages is configured to sort the washed soil. The selected soil 90 is approximately 3 mm in size.

그리고 오염토양에 세척수를 고압분사 하여 세척하고, 배출되는 세척수를 저장하기 위한 1차 저장탱크(60)를 형성한다. 상기 1차 저장탱크(60)는 모터(190)의 동력을 전달받아 회전하는 회전축(191)에 형성된 교반날개(192)가 회전하면서 세척수를 교반함과 동시에 폭기과정을 계속적으로 반복실행 구성이다.Then, the washing water is washed by high pressure spraying on the contaminated soil, and a primary storage tank 60 for storing the discharged washing water is formed. The primary storage tank 60 is configured to repeatedly execute the aeration process while stirring the washing water while rotating the stirring blade 192 formed on the rotating shaft 191 to receive the power of the motor 190 rotates.

상기 1차 저장탱크(60)에 저장된 세척수에는 워싱스크린장치(50)에서 미처 분리되지 못한 오염물질이 혼합된 토양이 혼합되어 있다. 따라서 1차 저장탱크(60)에 저장된 세척수를 정화하기 위하여 약품탱크(170)에서 정화제인 계면활성제를 투입하도록 구성되어 있다. The washing water stored in the primary storage tank 60 is mixed with soil mixed with contaminants not separated by the washing screen device 50. Therefore, in order to purify the wash water stored in the primary storage tank 60, the chemical tank 170 is configured to add a surfactant as a purifier.

상기 1차 저장탱크(60)에서 정화제와 혼합되면서 교반된 세척수는 다시 벤튜리관(70)을 거쳐 2차 저장탱크(61)로 이송되어 교반됨과 동시에 폭기과정을 반복 실행하도록 구성된다. 이때 상기 벤튜리관(70)은 정화제가 혼합 교반된 세척수를 고압으로 유입되도록 다수개의 고압노즐로 분사되게 구성함과 동시에 처리수조저장탱크(40)에 저장된 세척수를 공급하여 와류형태로 고압 분사시켜서 오염토양의 입자간 충돌 및 마찰작용으로 토양입자에 흡착된 오염물질을 탈착시키는 한편, 벤튜리관(70)에서 고압 분사작용으로 압력과 밀도가 급격히 낮아져 입자가 확산되면서 토양입자에 흡착된 오염물질이 탈착하여 세척됨으로써, 오염토양에 흡착된 오염물질을 효과적으로 세척하여 토양을 복원할 수 있도록 구성하였다.(본 출원인이 등록받은 특허 제950696호를 사용함)The washing water stirred while being mixed with the purifying agent in the primary storage tank 60 is transferred to the secondary storage tank 61 through the venturi tube 70 and stirred, and is configured to repeatedly perform the aeration process. In this case, the venturi tube 70 is configured to be sprayed into a plurality of high pressure nozzles so that the purified water mixed with the purifying agent is introduced at a high pressure, and at the same time, supplying the washing water stored in the treatment tank storage tank 40 to contaminate the high pressure in a vortex form. Contaminants adsorbed to the soil particles by collisions and friction between the soil particles are desorbed, while pressure and density are drastically lowered due to high pressure injection in the venturi tube 70, and as the particles diffuse, the contaminants adsorbed on the soil particles are desorbed. It is configured to effectively restore the soil by washing the contaminants adsorbed on the contaminated soil by using the rinse.

상기 2차 저장탱크(61)에서 교반작용 및 폭기과정을 거친 세척수에 미처 준리되지 못한 토양(91)을 선별하기 위한 탈수스크린(80)이 구성되어 있다. 이때 상기 탈수스크린(80)에서 선별된 토양 역시 3mm 정도의 토양(모래)(91)이 선별된다.In the secondary storage tank 61, a dehydration screen 80 for screening soil 91 which is not yet treated in the washing water that has undergone the stirring and aeration process is configured. At this time, the soil selected by the dehydration screen 80 is also selected for the soil (sand) 91 of about 3mm.

또한, 세척수는 다시 하이드로 사이클론(180)에서 원심력으로 회전되어 세척수에 잔존하는 슬러지를 분리시키도록 구성한다. 상기와 같은 구성은 차량(100)에 설치된 오염토양 세척장치에서 간단하게 이루어진다.
In addition, the wash water is again rotated by centrifugal force in the hydrocyclone 180 is configured to separate the sludge remaining in the wash water. Such a configuration is simply made in the contaminated soil washing apparatus installed in the vehicle (100).

이와 같이 본 발명은 오염토양에 혼합된 금속을 금속분리장치(30)에서 제거한 후, 탈수스크린장치(50)에서 고압분사되는 세척수로 세척하여 세척된 토양(90)을 1차 선별하고, 세척수에 잔존하는 토양은 다시 1차 저장탱크(60)와 벤튜리관(70)을 거쳐 2차 저장탱크(61)를 거치면서 교반작용과 폭기작용을 거치면서 분리된 토양(91)을 탈수스크린(80)에서 2차 분리한다.As described above, the present invention removes the metal mixed in the contaminated soil in the metal separation device 30, and then washes the washing soil with high pressure sprayed in the dewatering screen device 50 to first sort the washed soil 90, and The remaining soil is again passed through the primary storage tank (60) and the venturi tube (70) through the secondary storage tank (61), and the soil (91) separated through the stirring action and the aeration action screen (80). Secondary separation at

그리고 탈수스크린(80)에서 배출된 세척수는 다시 하이드로 사이클론(180)을 거쳐 원심분리되면서 잔여 세척된 토양(91)을 분리하여 배출하는 공정을 거치게 된다.
In addition, the washing water discharged from the dehydration screen 80 is subjected to a process of separating and discharging the remaining washed soil 91 while being centrifuged through the hydrocyclone 180 again.

따라서 본 발명은 오염토양이 있는 현장으로 차량을 이동하여 현장에서 즉시 오염토양을 세척하여 세척선별된 토양을 분리하여 재활용이나 재사용을 극대화시켜서 예산을 절감할 수 있도록 하였다.Therefore, the present invention was to move the vehicle to the site with contaminated soil to immediately wash the contaminated soil in the field to separate the selected soil to be washed to maximize recycling or reuse to reduce the budget.
