Description

광산폐수의 산화중화처리용 액상소석회의 막힘방지시스템{Clogging prevention system of liquid slaked lime for oxidative neutralization treatment of mine wastewater}Clogging prevention system of liquid slaked lime for oxidative neutralization treatment of mine wastewater

본 발명은 광산폐수의 산화중화처리용으로 사용되는 액상소석회에 의한 관로 및 펌프의 막힘을 방지할 수 있도록 한 광산폐수의 산화중화처리용 액상소석회의 막힘방지시스템에 관한 것이다. The present invention relates to a clogging prevention system for liquid slaked lime for oxidative neutralization treatment of mine wastewater, which can prevent clogging of pipelines and pumps by liquid slaked lime used for oxidative neutralization treatment of mine wastewater.

국내에는 900여개의 금속광산, 380여개의 석탄광산 및 1,200여개의 비금속광산을 포함하여 총 2,500개소의 크고 작은 광산들이 있으며, 이들 중에서 약 80%가 휴광 또는 폐광된 광산으로서 적절한 환경복원시설이 설치되지 않아 주변 생태계가 위협받고 있다.In Korea, there are a total of 2,500 large and small mines, including 900 metal mines, 380 coal mines, and 1,200 non-metal mines. As a result, the surrounding ecosystem is threatened.

특히 폐금속 광산에서는 과거 채광이나 선광 제련과정 등의 광산활동으로 인하여 배출된 광산폐기물들(폐석, 광미, 광석광물, 광산배수(AMD : Acid Mine Drainage 또는 ARD : Acid Rock Drainage))이 광산주변에 그대로 방치되어있어 집중 강우나 강풍에 의해 하부로 분산되어 광산하부의 농경지와 수계로 흘러들어 환경을 계속해서 오염시키고 있는 실정이다. In particular, in waste metal mines, mine wastes (waste-rock, tailings, ore minerals, and mine drainage (AMD: Acid Mine Drainage or ARD: Acid Rock Drainage)) discharged from mining activities such as mining or beneficiation smelting in the past are collected around the mine. As it is left unattended, it is dispersed to the lower part by concentrated rainfall or strong wind and flows into the agricultural land and water system under the mine, continuously polluting the environment.

이렇게 오염된 토양이나 하천수는 농작물의 성장에도 영향을 미쳐 결국 이를 섭취하는 인간의 건강에 심각한 문제를 야기한다.Such polluted soil or river water also affects the growth of crops, eventually causing serious problems to the health of humans who consume it.

광산 활동에 의해 발생되는 폐수(이하, "광산폐수"라 한다)는 다른 산업시설과 달리 광산 활동이 중단된 후에도 수년 동안 발생하는데, 이 광산 폐수는 pH가 3~6정도로 낮은 산성수로서 주변 광석에 함유되어 있는 철, 망간, 아연, 구리 등의 중금속 성분을 용출시켜 인접 수계로 유출된다. Wastewater generated by mining activities (hereinafter referred to as "mine wastewater") is generated for many years after the mine activity is stopped, unlike other industrial facilities. This mine wastewater is acidic water with a low pH of 3 to 6, It elutes heavy metal components such as iron, manganese, zinc, and copper contained in it and flows into the adjacent water system.

이러한 산성수의 중화처리로 주로 강한 알칼리성을 띤 액상소석회를 투입하고 있는데, 이러한 액상소석회는 소석회분말을 물에 희석한 것이 때문에 공급속도이 느리거나, 공급을 멈출 때 소석회분말이 퇴적되어 액상소석회를 공급하는 관로 및 펌프가 막히는 문제점이 있었다.Liquid slaked lime with strong alkalinity is mainly injected as a neutralization treatment of acidic water. This liquid slaked lime is supplied by diluting slaked lime powder with water, so the supply rate is slow or when supply is stopped, slaked lime powder is deposited to supply liquid slaked lime. There was a problem that the pipeline and the pump were clogged.

이렇게 관로 및 펌프가 막히게 되면 그 관로 및 펌프를 모두 분해하여 청소하여야 하므로 유지보수가 번거로움은 물론 시간손실이 발생하는 문제점으로 이어지고 있었다.If the pipe line and the pump are clogged in this way, it is necessary to disassemble and clean the pipe line and the pump, so maintenance is cumbersome as well as time loss.

참고로, 하기의 선행기술문헌은 특허정보넷 키프리스를 통해 "광산폐수"를 키워드로 하여 검색된 최근의 선행기술문헌 4건을 등재한 것으로, 하기의 선행기술문헌을 참고하여 본 발명에 관한 기술분야와 배경기술 및 그 발전상태를 파악할 수 있을 것이다.For reference, the following prior art literature is a list of four recent prior art documents searched for with the keyword "mining wastewater" through the Patent Information Net Cypris. and background technology and its development status.

도시된 바와 같이 본 발명은 우선 광산폐수를 산화중화처리하는 산화중화조(10); 상기 산화중화조(10)에 액상소석회저장탱크(21)로부터 관로(22) 및 그 관로(22)에 설치되는 펌프(23)에 의해 액상소석회가 공급되도록 하는 액상소석회공급라인(20);을 포함하고, 상기 액상소석회공급라인(20)이 소석회의 퇴적에 의해 공급속도이 저하되거나 막힐 경우 개통되도록 하는 수단을 포함하는 것을 근본적인 특징으로 한다. As shown, the present invention first comprises: an oxidation neutralization tank 10 for oxidizing and neutralizing the mine wastewater; A liquid slaked lime supply line 20 for supplying liquid slaked lime to the oxidation neutralization tank 10 from a liquid slaked lime storage tank 21 by a pipeline 22 and a pump 23 installed in the pipeline 22; It is fundamentally characterized in that it includes a means for opening the liquid slaked lime supply line 20 when the supply rate is reduced or blocked by the deposition of slaked lime.

상기 액상소석회공급라인(20)이 소석회의 퇴적에 의해 공급속도이 저하되거나 막힐 경우 개통되도록 하는 수단은 도시된 바와 같이 상기 액상소석회저장탱크(21)로부터 산화중화조(10)로 연결되는 관로(22) 및 그 관로(22)에 설치되는 펌프(23)로 이루어지는 액상소석회공급라인(20)을 2개소 이상으로 설치하고, 상기 각 액상소석회공급라인(20)에 세척탱크(31)로부터 산성용액을 공급하여 순환되도록 하는 세척라인(30);을 구성한 것을 구체적인 특징으로 한다. The means for opening the liquid slaked lime supply line 20 when the supply rate is reduced or blocked due to the deposition of slaked lime is a pipe 22 connected from the liquid slaked lime storage tank 21 to the oxidation neutralization tank 10 as shown. ) and the liquid slaked lime supply line 20 comprising the pump 23 installed in the pipeline 22 are installed at two or more places, and the acid solution is supplied from the washing tank 31 to each liquid slaked lime supply line 20 . It is a specific feature to configure the washing line 30 to supply and circulate.

더 구체적으로, 상기 세척라인(30)은 각 액상소석회공급라인(20)의 펌프(23)를 기준으로 하여 관로(22)의 선단과 말미에 3방밸브(24)를 구성하여 순환시킬 수 있다.More specifically, the washing line 30 can be circulated by configuring the three-way valve 24 at the tip and the end of the pipeline 22 based on the pump 23 of each liquid slaked lime supply line 20 . .

또한, 상기 세척라인(30)의 세척탱크(31)는 시수와 산성용액을 투입하여 액상소석회공급라인(20)의 처리수를 혼합교반하여서 액상소석회공급라인(20)으로 다시 공급하는 용해조(32); 액상소석회공급라인(20)의 처리수를 회수하여 퇴적된 소석회를 침강시키고 월류된 처리수를 용해조(32)로 공급하는 침강조(33);로 구성할 수 있다. In addition, the washing tank 31 of the washing line 30 injects city water and an acidic solution, mixes and stirs the treated water of the liquid slaked lime supply line 20, and supplies it back to the liquid slaked lime supply line 20 in a dissolution tank 32 ); It may consist of a; settling tank 33 that recovers the treated water from the liquid slaked lime supply line 20 to settle the deposited slaked lime and supplies the overflowed treated water to the dissolution tank 32 .

또한, 상기에서 산성용액은 황산, 구연산 등의 산류로 이루어지거나, 특히 광산폐수의 이물질을 여과한 처리수로 이루어질 수 있고, 시수는 광산폐수를 정화처리한 처리수로 이루어질 수 있다. In addition, in the above, the acidic solution may be made of acids such as sulfuric acid and citric acid, or in particular, may be made of treated water obtained by filtering foreign matter from the mine wastewater, and the municipal water may be made of treated water obtained by purifying the mine wastewater.

또한, 상기에서 침강조(33)에 침강된 소석회는 펌프(23)를 통해 산화중화조(10)로 공급될 수 있다. In addition, the slaked lime settling in the settling tank 33 may be supplied to the oxidation and neutralization tank 10 through the pump 23 .

본 발명의 작동방법은 광산폐수를 산화중화처리하는 산화중화조(10)로 공급되는 2개소 이상의 액상소석회공급라인(20) 중 가동되지 않는 액상소석회공급라인(20)은 세척라인(30)을 따라 순환하는 방식으로 운영되며, 가동 중에 있는 액상소석회공급라인(20)이 막혀 공급속도가 떨어질 경우 개통된 액상소석회공급라인(20)으로 바꿔서 액상소석회를 공급하는 방식으로 운용된다. In the operating method of the present invention, the non-operating liquid slaked lime supply line 20 among two or more liquid slaked lime supply lines 20 supplied to the oxidation neutralization tank 10 for oxidative neutralization treatment of mine wastewater is a washing line 30 . It is operated in a circulating manner, and when the supply speed is reduced because the liquid slaked lime supply line 20 in operation is clogged, the liquid slaked lime supply line 20 is changed to the opened liquid slaked lime supply line 20 and is operated in such a way that the liquid slaked lime is supplied.

이렇게 하면, 발명의 효과에 설명한 바와 같이 가동되지 않는 액상소석회공급라인(20)은 세척라인(30)을 따라 순환시켜 소석회의 퇴적에 의해 막힌 관로(22) 및 펌프(23)를 산성용액으로 용해시켜 개통되도록 하는 효과가 있음은 물론 액상소석회가 공급되지 않을 때 연속적으로 순환시켜 개통된 상태로 액상소석회의 공급을 대기 되도록 할 수 있는 효과가 있고, 이에 의해 산화중화조(10)에 공급되는 액상소석회공급라인(20)은 항상 막히지 않고 개통된 상태로 액상소석회를 공급할 수 있는 효과가 있다. In this way, as described in the effect of the invention, the liquid slaked lime supply line 20 that is not in operation circulates along the washing line 30 to dissolve the pipe line 22 and the pump 23 blocked by the deposition of slaked lime with an acidic solution. In addition to having the effect of allowing the liquid slaked lime to be opened, there is an effect of continuously circulating when the liquid slaked lime is not supplied, and waiting for the supply of the liquid slaked lime in an opened state, thereby providing the liquid phase supplied to the oxidation neutralization tank (10). The slaked lime supply line 20 has the effect of always supplying liquid slaked lime in an open state without being blocked.

또한, 세척탱크(31)에 공급되는 산성용액을 광산폐수의 이물질을 여과한 처리수로 사용할 경우 별도의 비용으로 산성용액을 구매하지 않아도 되는 효과가 있고, 침강조(33)에 침강된 소석회를 산화중화조(10)로 공급할 경우 폐기자원을 재활용할 수 있음은 물론 산화중화조(10)의 중화처리능력을 향상시킬 수 있는 효과가 있다. In addition, when the acid solution supplied to the washing tank 31 is used as treated water obtained by filtering foreign substances from the mine wastewater, there is an effect that it is not necessary to purchase the acid solution at a separate cost, and the slaked lime precipitated in the settling tank 33 is removed. When supplied to the oxidation and neutralization tank 10 , it is possible to recycle waste resources as well as improve the neutralization treatment capability of the oxidation and neutralization tank 10 .

이하, Below, 도2을Figure 2 참조하여 본 발명을 설명하면 다음과 같다. The present invention will be described with reference to the following.

도시된 바와 같이 본 발명은 액상소석회공급라인(20)에 사용되는 관로(22)는 내관(22a)의 외부에 외관(22b)을 갖는 이중관체로 구성하고, 상기 이중관체의 내관(22a)에 타공(22c)을 형성하며, 상기 이중관체의 외관(22b)의 내부에 시수를 공급하는 것을 포함할 수 있다. As shown, in the present invention, the pipeline 22 used in the liquid slaked lime supply line 20 is composed of a double tube body having an outer tube 22b on the outside of the inner tube 22a, and a hole is made in the inner tube 22a of the double tube body. Forming (22c), it may include supplying the time water to the inside of the exterior (22b) of the double tube body.

이렇게 하면, 관로(22)의 내관(22a)을 따라 액상소석회가 공급될 때 타공(22c)을 따라 공급되는 시수의 수압에 의해 소석회가 관로(22)에 퇴적되지 않는 효과가 있음은 물론 막힌 관로(22)를 뚫을 때 내관으로부터 퇴적된 소석회를 쉽게 이탈 시킬 수 있는 효과가 있다. In this way, when liquid slaked lime is supplied along the inner tube 22a of the pipeline 22, the slaked lime is not deposited in the pipeline 22 by the water pressure of the water supplied along the perforation 22c. When drilling (22), there is an effect that can easily separate the slaked lime deposited from the inner tube.

나아가, 상기 이중관체의 내관(22a) 외면에는 도시된 바와 같이 나선형으로 코일(22d)을 부착하는 것을 더 포함할 수 있다. Furthermore, the method may further include attaching a coil (22d) spirally to the outer surface of the inner tube (22a) of the double tube body as shown.

이렇게 하면, 외관(22b)의 내부로 공급되는 시수가 내관(22a)과 외관(22b) 사이의 코일(22d)을 따라 나선형으로 감기면서 시수가 공급되고, 이에 의해 시수의 공급압력이 향상시킬 수 있음은 물론 말단까지 균등하게 공급할 수 있는 효과가 있다. In this way, the time water supplied to the inside of the outer tube 22b is supplied while spirally wound along the coil 22d between the inner tube 22a and the outer tube 22b, whereby the water supply pressure can be improved. Of course, there is an effect that can supply evenly to the end.

더 바람직하게는 상기 타공(22c)의 크기는 내관(22a)의 선단은 작고 말미로 갈수록 크게 구성할 수 있다. More preferably, the size of the perforated hole 22c may be configured such that the tip of the inner tube 22a is small and the end thereof is large.
