Description

폐동선 및 폐동조각으로 황산동액을 제조하는 제조방법 및 그 장치{Method of manufacture of with waste copper wire and waste piece solution and apparatus thereof}Method for manufacture of with copper copper wire and waste piece solution and apparatus

본 발명은 폐동선 및 폐동조각을 묽은 황산수용액(황산 30-40%용액)을 채운처리조에 넣고 반응시키면서 처리조 내에 오존을 공급하여 산화동액을 제조하는 방법 및 그 장치에 관한 것을 특징으로 한다.The present invention is characterized by a method and apparatus for producing a copper oxide solution by supplying ozone into a treatment tank while reacting the waste copper wire and scrap copper scrap into a treatment tank filled with diluted sulfuric acid aqueous solution (30-40% sulfuric acid solution).

폐동선이나 폐동조각을 황산과 반응시켜서 황산동을 제조하는 방법은 여러가지 방법이 공지되어 있고 그중의 한 방법은 폐동선이나 폐동조각을 황산과 반응시키면서 질산을 가해 황산동을 제조하는 방법이 알려져 있다.Various methods are known for producing copper sulfate by reacting a waste copper wire or a scrap of copper with sulfuric acid, and one of them is a method of producing copper sulfate by adding nitric acid while reacting a waste copper or scrap of copper with sulfuric acid.

그러나 상기 제조방법은 질산의 사용량이 많아서 비용이 많이들뿐 아니라 질산을 사용하므로 인하여 처리시에 발생하는 공해물질을 안전하게 처리해야 하므로 이를 처리하기 위해 상당한 규모의 공해처리장치를 시설해야 하므로 막대한 비용이 들어가므로 황산동액 제조가격이 비싸게 되는 문제점이 있었다.However, the manufacturing method is expensive due to the large amount of nitric acid used, and because of the use of nitric acid, it is necessary to safely treat the pollutants generated at the time of treatment. There was a problem that the copper sulfate solution manufacturing price is expensive.

본 발명은 이러한 종래의 제조방법을 개량하여 새로운 제조방법을 개발하므로서 보다 염가의 비용으로 황산동액 제조가 가능케한 것인데 이는 폐동선 또는 폐동조각을 묽은 황산수용액에 넣어 반응시키면서 오존을 공급하여 동을 산화시키므로서 신속하게 황산동액을 제조할수 있게 개발한 것이다.The present invention allows the production of copper sulfate solution at a lower cost by developing a new manufacturing method by improving the conventional manufacturing method, which oxidizes copper by supplying ozone while reacting the waste copper wire or waste copper pieces in a dilute sulfuric acid solution. It was developed to produce copper sulfate solution quickly.

이를 보다 상세히 설명하면 다음과 같다.This will be described in more detail as follows.

도 1은 본 발명의 처리장치 예시도이다.1 is an exemplary view of a treatment apparatus of the present invention.

본 발명은 처리조 내에 폐동선 또는 폐동조각을 넣고 묽은 황산수용액(물 60-70%, 황산 30-40%)을 채워 반응시키면서 처리조 하측에서 오존을 공급하는 방법으로 이루어진다.The present invention consists of a method of supplying ozone from the bottom of the treatment tank while putting a waste copper wire or waste copper scrap into the treatment tank and reacting with a diluted sulfuric acid aqueous solution (60-70% water, 30-40% sulfuric acid).

따라서 본 발명은 폐동선이나 폐동조각을 묽은 황산수용액과 반응시키면서 오존을 공급하여 효과적으로 황산동액을 만들수 있다.Accordingly, the present invention can effectively make copper sulfate solution by supplying ozone while reacting waste copper wire or waste copper scrap with dilute sulfuric acid solution.

이를 위해 본 발명은 첨부도면과 같은 제조장치로서 가능하다.To this end, the present invention is possible as a manufacturing apparatus such as the accompanying drawings.

본 발명의 제조장치는 일정규격의 통체로 처리조(1)를 구성하고 그 하측에 구획망(2)을 설치하여 오존공급실(3)을 만들어 오존발생기(4)에서 발생된 오존을 공급할수 있게 구성하고 처리조 상부에는 투입구(1a)와 물 공급관(1b) 및 황산공급관(1c)을 장치하고 배기관(1d)을 구비하며 구획망(2)이 설치된 주벽 외측에 펌프(5)를 장치하여 구획망(2) 하측의 오존공급실(3)과 상측공간의 처리수를 순환시킬수 있게 순환관(5a)(5b)을 펌프와 연결시켜 순환장치를 갖추는 구성으로 이루어진다.The manufacturing apparatus of the present invention constitutes the treatment tank 1 with a cylinder of a certain standard and installs a compartment network 2 at the lower side thereof to create an ozone supply chamber 3 so that the ozone generated by the ozone generator 4 can be supplied. In the upper part of the treatment tank, an inlet 1a, a water supply pipe 1b and a sulfuric acid supply pipe 1c are provided, an exhaust pipe 1d is provided, and a pump 5 is provided outside the main wall where the partition network 2 is installed. The circulation pipe 5a, 5b is connected to a pump to circulate the ozone supply chamber 3 at the lower side of the network 2 and the treated water in the upper space.

도면에서 미설명부호 6은 황산동액 배출관이다.In the figure, reference numeral 6 is a copper sulfate liquid discharge pipe.

상기 제조장치는 처리조(1)의 투입구(1a)를 통해 구획망(2) 위에 폐동선 또는 동조각(가)이 적층되게 한 다음 30-40%의 농도를 유지하도록 물과 황산을 투입하여 조성시킨 묽은황산 수용액(나)을 체워 묽은 황산수용액 속에서 동이 반응되게 하면서 오존발생기에서 제조되어 공급되는 오존을 구획망(2)의 하측 오존공급실(3)에 공급하면 폐동선과 폐동조각이 묽은황산 용액과 반응하고 있는 상태에서 오존이 공급되어 동을 산화시키게 되고 산화된 동은 황산과 즉시 반응하여 황산동이 되므로 신속하게 황산동액을 제조할수 있게된다.The manufacturing apparatus is a waste copper or copper (a) is stacked on the partition network (2) through the inlet (1a) of the treatment tank (1), and then water and sulfuric acid is added to maintain the concentration of 30-40% When distilled sulfuric acid aqueous solution (b) is collected, copper is reacted in dilute sulfuric acid solution, and the ozone produced by the ozone generator is supplied to the lower ozone supply chamber (3) of the compartment network (2). In the state of reacting with the sulfuric acid solution, ozone is supplied to oxidize copper, and the oxidized copper reacts with sulfuric acid immediately to become copper sulfate, thereby rapidly preparing copper sulfate solution.

특히, 본 발명의 처리장치에는 오존공급실(3)과 구획망(2) 상부 공간이 순환관(5a)(5b)으로 연결되어서 펌프(5)를 작동시킴에 따라 내부공간의 용수를 순환시켜 주므로 오존의 공급과 반응을 촉진시켜 생산성을 높이게 된다.In particular, in the treatment apparatus of the present invention, the ozone supply chamber 3 and the upper space of the compartment network 2 are connected to the circulation pipes 5a and 5b to circulate the water in the internal space as the pump 5 is operated. Productivity is increased by promoting the supply and reaction of ozone.

그러므로, 본 발명은 염가의 생산비용으로 소망하는 황산동액의 제조가 가능하고 처리조(1)에 스팀 또는 가열히터 장치를 하므로써 생산효능을 더욱 촉진시킬수 있다.Therefore, the present invention can produce a desired copper sulfate solution at a low production cost and further promote the production efficiency by providing a steam or heating heater to the treatment tank 1.

따라서 이렇게 생산된 황산동액은 별도의 건조장치를 이용하여 건조시켜 황산동 1 수염으로 제조하여 사료첨가재로 사용하거나 황산동액을 냉각시켜 결정물질로 만들어서 도금재와 같은 산업분야에 널리 사용할수 있다.Therefore, the copper sulfate produced in this way can be dried using a separate drying device to produce copper sulfate 1 beard and used as feed additives or to cool the sulfate solution into a crystal material to be widely used in industrial fields such as plating materials.

< 실 시 례 ><Example>

폐동선 1톤을 처리조에 넣고 농도 35%의 황산수용액 8톤을 체운후 15-20kg의 오존을 2시간 공급하여 황산동액을 얻고 이를 건조시켜서 황산동 1수염 3, 4톤을 얻었다.1 ton of waste copper was placed in a treatment tank, and 8 tons of 35% sulfuric acid aqueous solution was filled, and 15-20 kg of ozone was supplied for 2 hours to obtain copper sulfate and dried to obtain 3 and 4 tons of copper sulfate monohydrate.

따라서 본 발명은 별도의 산화제를 공급하지 않고 묽은 황산용액 속에 오존을 공급하여 동을 산화시키는 방법으로 황산동액을 만들기 때문에 빠른 시간 내에 황산동액을 제조할수 있는 효과를 얻게되고 생산비용을 절감시킬수 있는 이점이 있으며 위험요소나 공해물질 발생요소가 거의 없어 단순화된 장치로 산화동액을 제조할수 있는 효과를 얻을수 있다.Therefore, in the present invention, since copper sulfate is prepared by supplying ozone in a dilute sulfuric acid solution without supplying a separate oxidizing agent, copper sulfate can be produced in a short time. There is little risk factor or pollutant generation factor, and it is possible to obtain the effect of producing copper oxide with a simplified device.
