첨부한 도면에 의하여 본 발명을 자세히 설명하면 다음과 같다.The present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 의한 세척조의 단면도이고, 도 2는 본 발명에 의한 세척의 사시도이다.1 is a cross-sectional view of the washing tank according to the present invention, Figure 2 is a perspective view of the washing according to the present invention.

도 1과 도 2에서와 같이 본 발명에 의한 세척조(10)의 원통형의 몸체(1) 내부에 세척수로(2)가 나선형태로 형성되고, 세척조(10)의 하부에는 세척수로(2)를 따라 흘러 내린 오염토양과 세척수가 저장되는 수실(3)이 형성된다.1 and 2 in the cylindrical body 1 of the washing tank 10 according to the present invention as shown in Figure 1 and the washing water passage (2) is formed in a spiral, the lower portion of the washing tank 10 to the washing water passage (2) A water chamber 3 is formed to store the contaminated soil and the washing water flowing down.

세척조(10)의 상부에서 오염토양과 세척수의 혼합물이 공급관(4)을 통해 세척수로(2)로 공급되면 오염토양과 세척수가 나선형태의 세척수로(2)를 따라 흐르면서 오염토양의 입자가 세척수와 충돌 및 마찰에 의해 토양에 흡착된 오염물질이 토양으로부터 분리되고 오염토양과 세척수는 수실(3)로 흘러내려 보관된다.When the mixture of contaminated soil and wash water is supplied from the upper part of the washing tank 10 to the washing water passage 2 through the supply pipe 4, the soil and washing water flow along the spiral washing water passage 2 and the particles of the contaminated soil wash water. The contaminants adsorbed to the soil by collisions and frictions are separated from the soil, and the contaminated soil and wash water flow down into the water chamber (3).

이때, 세척조(10)의 내부에 형성된 분사관(5)의 회전구(11)가 회전하면서 회전구(11)에 방사상으로 형성된 노즐(12)에서 세척수가 분사되면서 세척수로(2)를 타고 흘러내리는 오염토양과 세척수에 고압으로 분사되어 오염토양을 세척하게 된다.At this time, while the rotating hole 11 of the injection pipe 5 formed in the washing tank 10 rotates while washing water is sprayed from the nozzle 12 formed radially on the rotating hole 11, the washing water flows through the washing water passage 2. It is sprayed with high pressure on the polluted soil and washing water to clean the polluted soil.

만일, 토양의 오염물질이 중금속이라면 노즐(12)에서 염산이 고압분사되어 오염토양의 중금속과 염산이 화학반응하여 토양으로부터 중금속을 분리하게 된다.If the pollutant in the soil is a heavy metal, hydrochloric acid is sprayed at high pressure in the nozzle 12, and the heavy metal and hydrochloric acid in the contaminated soil are chemically separated to separate the heavy metal from the soil.

나선형의 세척수로(2)를 흘러 세척조(10)의 하부에 형성된 수실(3)로 이동된 오염토양과 세척수는 펌프(6)에 의해 배출파이프(7)로 고압 토출된다.The contaminated soil and the washing water which flowed through the spiral washing water passage 2 to the water chamber 3 formed in the lower portion of the washing tank 10 are discharged at a high pressure into the discharge pipe 7 by the pump 6.

이때, 펌프(6) 내부의 고속회전하는 임펠러(Impeller)에 의해 오염토양과 세척수가 강하게 상호 교반되면서 오염토양에 흡착된 오염물질이 분리된다.At this time, the contaminant adsorbed on the contaminated soil is separated by strongly stirring the contaminated soil and the washing water by an impeller (Impeller) rotating at a high speed inside the pump 6.

펌프(6)에 의해 고압으로 토출된 오염물질과 세척수는 배출파이프(7)의 내부에 형성된 스크류형태의 교반장치(9)에 의해 강하게 회전하면서 난류(亂流) 흐름으 로 변하게 된다. Contaminants and washing water discharged at a high pressure by the pump 6 are changed into a turbulent flow while being strongly rotated by a screw-type stirring device 9 formed inside the discharge pipe 7.

도 3에서와 같이 교반장치(9)는 스크류형태로 형성되어 펌프(6)에 의해 고압으로 토출된 오염토양과 세척수가 스크류형태의 교반장치(9)에 충돌하면서 교반되어 오염토양에 흡착된 오염물질이 분리되면서 토양이 세척되는 것이다.As shown in FIG. 3, the stirring device 9 is formed in the form of a screw, and the contaminated soil discharged at high pressure by the pump 6 and the washing water are agitated while being impinged on the screw-type stirring device 9. As the material separates, the soil is washed.

만일, 토양의 오염농도가 심할 경우에는 도 4와 같이 세척조(10)를 2~4개를 직렬로 연결하여 오염토양을 세척할 수 있다.If the pollution concentration of the soil is severe, as shown in Figure 4 by connecting two to four washing tanks 10 in series it can wash the contaminated soil.

만일, 토양의 오염농도가 심하지 않을 경우에는 도 5에서와 같이 공급관(4)으로 공급된 오염토양과 세척수를 세척조(10)로 공급하지 않고, 공급관(4)을 바로 임펠러형 펌프(6)와 연결하여 배출파이프(7)로 고압토출하고, 고압토출된 오염토양과 세척수는 배출파이프(7) 내부에 구성된 스크류형태의 교반장치(9)에 의해 오염토양에 흡착된 오염토양을 세척함으로써 오염토양을 세척할 수 있다.If the pollution concentration of the soil is not severe, as shown in FIG. 5, the condensed soil and the washing water supplied to the supply pipe 4 are not supplied to the washing tank 10, and the supply pipe 4 is directly connected to the impeller pump 6. High pressure discharge to the discharge pipe (7) by connecting, high pressure discharged contaminated soil and washing water is contaminated soil by washing the contaminated soil adsorbed to the contaminated soil by a screw-type stirring device (9) configured inside the discharge pipe (7) Can be washed.

즉, 토양의 오염농도가 심할 경우에는 오염토양과 세척수가 공급되는 공급관(4)을 세척조(10)로 공급하여 세척하고, 토양의 오염농도가 심하지 않을 경우에는 오염토양과 세척수가 공급되는 공급관(4)을 펌프(6)를 이용하여 배출파이프(7)로 고압토출함으로써 배출파이프(7) 내부의 교반장치(9)에서 오염토양을 세척할 수 있는 것이다.In other words, when the soil is heavily polluted, the supply pipe 4 for supplying the contaminated soil and wash water is supplied to the washing tank 10, and when the soil is not heavily polluted, the supply pipe for supplying the contaminated soil and the wash water is provided. 4) by using the pump 6 to discharge the high pressure to the discharge pipe (7) it is possible to wash the contaminated soil in the stirring device (9) inside the discharge pipe (7).

상기와 같이 펌프(6)와 교반장치(9)로 구성된 본 발명은 호퍼, 진동탈수장치, 싸이클론(Cyclone), 침전조등의 여러 장치로 구성된 대형 오염토양 세척장치의 오염토양세척 효율을 증대시키기 위해 대형 오염토양 세척장치의 일부 구성장치로 사용될 수 있을 뿐 아니라, 본 발명 자체로도 오염토양을 세척할 수 있다.The present invention constituted by the pump 6 and the stirring device 9 as described above to increase the contaminated soil washing efficiency of the large contaminated soil washing device composed of several devices such as hopper, vibration dehydration device, cyclone, sedimentation tank, etc. Not only can be used as a component of the large contaminated soil washing apparatus, but the present invention itself can be used to clean contaminated soil.

이상에서 살펴본 바와 같이 본 발명의 기술적 핵심은 세척조(10)의 원통형 몸체(1) 내부에 세척수로(2)를 나선형을 구성함으로써 오염토양과 세척수가 세척수로(2)를 타고 흐르는 동안 오염토양의 입자가 세척수와 충돌하면서 오염물질이 토양으로부터 분리되고, As described above, the technical core of the present invention constitutes a spiral structure of the washing water passage 2 inside the cylindrical body 1 of the washing tank 10 so that the contaminated soil and the washing water flow through the washing water passage 2. As the particles collide with the wash water, the contaminants are separated from the soil,

또한, 펌프(6)에서 배출파이프(7)로 고압 토출된 오염토양과 세척수가 배출파이프(7)내에 구성된 교반장치(9)에 의해 난류흐름으로 변환되어 오염토양에 흡착된 오염물질이 토양으로부터 분리 세척되도록 구성한 것이다.In addition, the contaminated soil discharged at high pressure from the pump 6 to the discharge pipe 7 and the washing water are converted into turbulent flow by the stirring device 9 configured in the discharge pipe 7 so that the contaminants adsorbed to the contaminated soil are removed from the soil. It is configured to be separated and washed.

이상에서 살펴본 바와 같이 본 발명은 다이옥신이나 농약등의 유기물, 기름등의 유류 및 중금속등의 다양한 오염물질에 의해 오염된 토양을 세척할 수 있고, 그 구조가 간단하면서도 오염토양 세척효율이 우수한 오염토양 세척장치로서 급속한 산업발전에 따른 오염된 토양을 효율적으로 세척할 수 있는 매우 유용한 발명이다.As described above, the present invention can wash soil contaminated by various contaminants such as organic materials such as dioxins and pesticides, oils such as oils, and heavy metals, and its structure is simple but the contaminated soil has excellent contaminant soil cleaning efficiency. As a washing device, it is a very useful invention that can efficiently clean contaminated soil caused by rapid industrial development.
