Description

오염토양 정화장치{The purification apparatus of a contamination soil}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

본 발명은 오염토양 정화장치에 관한 것으로서, 더욱 상세하게는 투입구와 배출구가 수직으로 연결된 처리탱크 내부에 다수개의 교반날개를 갖는 회전축을 설치하고 상기 회전축 내부에는 약품을 공급하여 교반날개들 사이로 분사되도록 함으로써, 오염토양의 화학적 처리가 가능하고 또한 토양의 오염원이 쉽게 이탈 제거되도록 하였으며, 특히 중금속에 오염된 토양은 약품처리하지 않고 상기 회전축에서 고압공기를 분사하여 토양의 유동성을 증가시킨 뒤 별도의 건조실, 전처리실 및 가열로에서 열분해 제거되도록 하여 오염토양의 화학적 처리 및 증기추출이 가능하고 또한 열분해 처리의 전단계 공정으로 활용가능한 다기능의 오염토양 정화장치에 관한 것이다. The present invention relates to a contaminated soil purging apparatus, and more particularly, to a polluted soil purging apparatus having a rotary shaft having a plurality of stirring blades inside a treatment tank in which an inlet and an outlet are vertically connected to each other, In particular, the soil contaminated with heavy metals is sprayed with high-pressure air from the rotary shaft without chemical treatment, thereby increasing the fluidity of the soil, , A pretreatment chamber and a heating furnace, thereby enabling the chemical treatment and steam extraction of the contaminated soil, and also a multi-function contaminated soil remediation apparatus which can be used in the previous stage of pyrolysis treatment.

일반적으로 주유소 및 유류저장탱크가 설치된 곳은 지반 내부로 기름이 유출되어 토양이 오염되는 실정이다. 오염토양을 정화시키는 방법으로 화학적처리, 증기추출법 및 열분해 처리법 등이 있다. 화학적처리란 계면활성제 및 산화제 등의 약품을 이용하여 토양으로 부터 오염원을 분리 제거하는 기술이다. 이 과정에서 흡착기를 이용하여 유증기 등의 유해가스를 흡착 제거하는 증기추출법이 병행 시행된다.
종래에는 토양을 굴착하여 오염원을 제거하는 장치로 국내실용등록 제410721호는 토양에 약품을 분사하여 세척하면서 토양이 투입된 일측단부에서 토양이 배출되는 타측단부로 토양을 이송시키는 하나의 세척스크류를, 직경과 피치가 변화하지 않는 후방스크류와, 직경과 피치가 전방으로 갈수록 감소하는 전방스크류로 구분하여 약품과의 혼합 효율을 증가시킨 것이다.
그러나 종래의 장치는 오염토양을 전,후방 스크류에서 계속 밀어내는 구조이므로 토양의 공극이 좁아져 실질적으로 약품과 토양의 혼합률이 떨어지고 단순 밀어내는 구조만 갖는 것이므로 오염토양의 정화성능 개선을 기대하기 어려웠다.
국내특허 제404738호는 내부에 이중관 형태로 구성하여 내측 케이싱에는 오염토양을 밀어내는 스크류가 구비되고 외측 케이싱은 상기 스크류와 역방향으로 회전되는 통으로 구성하여 오염 토양을 단계별 처리하는 구성이나, 이것 역시 내,외통을 이중관으로 구성하고 외통은 회전시키는 구성이므로 구조가 복잡하고, 오염 토양을 파쇄하거나 확산시켜 공극을 넓혀주는 구성은 없으므로 약품과 오염토양의 혼합성능을 크게 기대하기는 어려운 단점이 있었다.Generally, where gas stations and oil storage tanks are installed, oil is leaked into the ground and the soil is contaminated. Methods for purifying contaminated soil include chemical treatment, steam extraction and pyrolysis treatment. Chemical treatment is a technology for separating and removing contaminants from soil by using chemicals such as surfactants and oxidizing agents. In this process, a vapor extraction method for adsorbing and removing harmful gas such as vapor is performed in parallel using an adsorber.
Conventionally, the Korean Utility Registration No. 410721 discloses a device for removing contamination by excavating soil. Japanese Utility Model Registration No. 410721 discloses an apparatus for cleaning soil by washing a single cleaning screw for transferring soil from one end of the soil into the other end, Rear screw which does not change the diameter and pitch and front screw which the diameter and pitch decrease toward the front are increased and the mixing efficiency with chemicals is increased.
However, since the conventional apparatus has a structure in which the contaminated soil is continuously pushed out from the front and rear screws, the air gap of the soil narrows, and the mixing ratio of the chemicals and the soil is substantially lowered. It was difficult.
Korean Patent No. 404738 discloses a structure in which the inner casing is formed with a double pipe structure, the inner casing is provided with a screw pushing the contaminated soil, and the outer casing is composed of a cylinder rotated in the direction opposite to the screw, , The outer tube is composed of a double pipe and the outer tube is rotated. Therefore, the structure is complicated, and there is no constitution to expand the air gap by crushing or diffusing the contaminated soil, so that it is difficult to expect a high mixing performance of the chemical and the contaminated soil.

And a charging bucket 13 for injecting a predetermined amount into the tank 10 is provided. The loading bucket 13 is formed by a plurality of plate or arcuate buckets extending in the axial direction and rotated by a motor 13a so that the loading port 11 is blocked by the buckets in a stopped state, Make the interior close to the enclosure. Therefore, it is possible to prevent the vapor gas generated during the chemical treatment process of contaminated soil from being exhausted to the outside of the inlet 11 as much as possible.

그리고 상기 투입구(11)와 투입버킷(13) 사이에는 스프링 같은 탄성체의 연결부(11a)가 구비되어 투입구(11)가 탄성적으로 지지되도록 해준다. 상기 배출구(12)에는 모터(14a)로 회전되는 배출버킷(14)이 구비되어 정화된 토양을 하부로 배출시킨다. 상기 배출버킷(14)은 토양을 처리하는 동안 정지상태를 이뤄 오염토양이 배출구(12)로 흘러내리지 않고 처리탱크(10) 내부에 체류되도록 해준다.A connecting portion 11a of a spring-like elastic body is provided between the charging port 11 and the charging bucket 13 so that the charging port 11 is elastically supported. The discharge port (12) is provided with a discharge bucket (14) rotated by a motor (14a) to discharge purified soil downward.

이처럼 구성된 본 발명 한 실시예는 오염지역의 토양을 선별기에 투입하여 자갈과 이물질을 걸러내고 포크레인같은 중장비를 이용하여 투입구(11)에 오염토양을 투입한다. 이때 모터(13a)로 회전되는 투입버킷(13)이 작동되어 오염토양을 적극적으로 처리탱크(10) 내부로 낙하시킨다. 또한 포크레인으로 토양을 투입할때 투입구(11)를 간헐적으로 두둘겨서 연결부(11a)의 탄성으로 투입구(11)가 흔들리도록 하여 투입구(11)의 막힘을 예방한다. In the embodiment of the present invention constructed as described above, the soil in the contaminated area is put into the separator to filter the gravel and foreign matter, and the contaminated soil is introduced into the inlet 11 using heavy equipment such as a fork. At this time, the charging bucket 13 rotated by the motor 13a is actuated to actively drop the contaminated soil into the treatment tank 10. [ Also, when the soil is introduced into the forklift, the charging port 11 is intermittently tucked so that the charging port 11 is shaken by the elasticity of the connecting portion 11a, thereby preventing clogging of the charging port 11. [

상기 처리탱크(10) 내부로 오염토양이 적재되면 모터(20a)를 이용하여 각 회전축(20)을 회전시킨다. 이때 회전축에 형성된 다수개의 교반날개(22)들에 의해 오염토양이 휘저어져 뭉쳐진 오염토양이 분해된다. 이와 동시에 주입구(24)로 약품을 투입하여 회전축(20)의 각 노즐(23)에서 약품이 토양으로 분사되도록 하면 교반날개(22)에 의해 약품과 토양이 잘 섞이면서 오염원이 토양에서 분리된다. 그리고 화학처리 과정에서 발생되는 유증기는 상부의 배기관(15) 및 배기구(15a)와 연결된 배기팬으로 흡입된 뒤 유증기 회수기, 흡착기 및 탈취기를 거져 무공해 상태로 배기된다.When contaminated soil is loaded into the treatment tank 10, the rotary shaft 20 is rotated using a motor 20a. At this time, the contaminated soil is agitated by the plurality of stirring vanes (22) formed on the rotating shaft, and the agglomerated contaminated soil is decomposed. At the same time, chemicals are injected into the injection port 24 so that the chemicals are injected into the soil from the nozzles 23 of the rotary shaft 20, so that the chemicals and the soil are well mixed by the stirring blades 22 and the contaminants are separated from the soil. Then, the vapor generated in the chemical treatment process is sucked into the exhaust fan connected to the exhaust pipe 15 and the exhaust port 15a, and exhausted in a polluted state through a vapor recovery device, an adsorption device and a deodorizer.

또한 처리탱크(10)의 하부에는 다수개의 에어노즐(30)이 구비되어 오염토양의 유동성을 증가시키므로 약품과 오염토양이 적극적으로 혼합된다. 처리탱크(10)에서 약품처리된 오염토양은 배출버킷(14)에 의해 정량 배출되어 다음 공정으로 이송된다. In addition, a plurality of air nozzles 30 are provided in the lower portion of the treatment tank 10 to increase the fluidity of the contaminated soil, so that the chemicals and the contaminated soil are positively mixed. The contaminated soil chemically treated in the treatment tank 10 is discharged in a quantitative manner by the discharge bucket 14 and transferred to the next process.

위의 과정은 오염토양을 화학적으로 처리하는 과정이며, 다음은 열분해 처리과정을 설명한다.The above process is the process of chemically treating the contaminated soil, and the following describes the pyrolysis process.

토양이 중금속에 오염된 경우 약품을 토양에 투입하지 않고 처리탱크(10) 내부에서 교반날개(22)로 휘저어 유동성만 증가시킨다. 이때 회전축(20)에는 주입구(24)로 고압공기를 주입하여 노즐(23)에서 고압공기가 토양으로 분사되어 유동성을 높이도록 해준다. 그리고 하부의 에어노즐(30)에서도 고압공기가 분사되면 토양의 유동성이 증가된 상태로 배출구(12)에서 배출된다.When the soil is contaminated with heavy metals, the chemicals are not added to the soil but stirred with the stirring wing (22) inside the treatment tank (10) to increase the fluidity only. At this time, high-pressure air is injected into the rotary shaft 20 through the injection port 24, and high-pressure air is injected into the soil from the nozzle 23 to enhance fluidity. When the high-pressure air is also sprayed from the lower air nozzle 30, the fluid is discharged from the discharge port 12 in an increased fluidity of the soil.

배출된 토양은 별도의 열분해기로 공급되어 건조실, 전처리실 및 가열로를 거치면서 중금속이 열분해되어 오염토양이 정화된다.The discharged soil is supplied to a separate pyrolyzer, and the heavy metal is pyrolyzed through the drying chamber, the pretreatment chamber and the heating furnace to purify the contaminated soil.
