Description

정수장 슬러지를 활용한 양질의 원 적외선 방사체 및 인공토양의 제조법{.}Preparation of High Quality Far Infrared Emitter and Artificial Soil Using Water Treatment Plant Sludge {.}

그동안 많은 원적외선 방사체가 수입 또는 제조되어 일상 생활에 널리 활용중이나 원석을 그대로 사용하거나 고가의 물질을 첨가하여 사용중이었다Many far-infrared emitters have been imported or manufactured so that they are widely used in daily life, using raw materials as they are, or adding expensive materials.

이에 국내는 물론 전 세계적으로 대량으로 발생되어 폐기물로 처리되던 정수장 슬러지를 이용하여 원적외선 방사체를 제조하기 위한 방법이다Therefore, it is a method for manufacturing far-infrared radiator using water treatment plant sludge that has been generated in large quantities not only in Korea but also worldwide.

산업 및 일상 생활에서 원적외선 방사체를 활용하기 위해서는 가공 및 기타 목적이 쉽게 하기위해 미세한 분말로 2차 가공이 필요했으나 정수장 슬러지는 이미 약 의 미세한 입자 구조를 가지고 있어 2차 가공이 불필요하며 다량의 수분 및 유기물만 처리하면 그 자체로도 양질의 인공토양 및 원적외선 방사체가 제조되며 여기에 필요한 화학성분의 무기물을 첨가하여 제조하면 되는 것이다In order to utilize far-infrared emitters in industrial and daily life, secondary processing was required with fine powders for easy processing and other purposes, but water purification plant sludge already has a fine grain structure of about 2, which does not require secondary processing, If only organic matter is processed, it can produce high quality artificial soil and far-infrared emitter by itself, and it needs to be prepared by adding inorganic chemicals necessary for it.

따라서 본 발명의 주요 목적은 대량으로 발생되는 폐기물을 활용하여 원적외선 방사체 및 인공토양을 제조하여 저가 및 대량 공급이 가능한 물질로 재생 하고자함이 주요 목적이다Therefore, the main object of the present invention is to manufacture far-infrared radiators and artificial soils using wastes generated in large quantities, and to regenerate them into materials that can be supplied at low cost and in large quantities.

또한 이로 인한 고 부가가치 상품의 제조가 가능한 것이 본 발명의 주요 목적이다In addition, it is the main object of the present invention to be able to manufacture high value-added products thereby.

폐기물 재활용을 위한 고열을 사용하여 수분 및 유기물을 제거하는 폐기물 재활용 응용 분야 및 이로 인한 원적외선 방사체 및 인공토양의 제조 분야이다Waste recycling applications that remove moisture and organics using high heat for waste recycling, and thus the manufacture of far-infrared radiators and artificial soils.

다량의 수분 및 유기물을 함유한 정수장 슬러지를 회전로 (로타리로)를 사용하여 그 성분을 제거하고 정수장 슬러지내의 순수 무기물만 채취하여 이것을 그대로 인공토양으로 사용 하거나 여기에 원적외선 방사 효과가 뛰어난 제3의 물질을 첨가하여 양질/저가의 원 적외선 방사체를 제조하는 것이다Water treatment plant sludge containing a large amount of water and organic matter is removed using a rotary furnace (rotary furnace), and only the pure minerals in the water treatment plant sludge are collected and used as artificial soil as it is, or a third Addition of materials to produce high quality / low cost far infrared emitters

제1도는 다량의 수분과 유기물을 함유한 정수장 슬러지를 처리하는 공정도이고1 is a process chart for treating sludge of water purification plant containing a large amount of water and organic matter.

<표3>은 이렇게 처리된 정수장 슬러지에 화학성분을 첨가하여 양질의 원적외선 방사체를 제조하는 방법의 예이다<Table 3> is an example of the production of high quality far-infrared radiator by adding chemical components to the treated plant sludge.

다음의 발명의 구성 및 작용은 통상의 지식을 가진 자가 쉽게 실행할 수 있도록 그 실행방법을 예시한 것이다The configuration and operation of the following invention is an example of the implementation method so that those skilled in the art can easily carry out.

( 발명의 구성 )(Configuration of the Invention)

1) 발생되는 정수장 슬러지의 주요 성분1) Main Components of Sludge

2)<표2>와 같은 성분의 정수장 슬러지의 불필요한 성분 (수분,유기물)을 제거하기 위해서는 약 1200도 이상의 고열로 약 10분이상 처리를 거쳐야 한다2) In order to remove unnecessary components (moisture, organic matter) from the water purification plant sludge of <Table 2>, it should be treated for about 10 minutes at a high temperature of about 1200 degrees or more.

그 처리 방법은 수거된 정수장 슬러지와 황토를 약 10:1비율로 혼합하여 1차 수분을 황토로 흡수 시킨후 회전식로 (로타리로)에 투입한다The treatment method is to mix the collected water treatment plant sludge with loess at a ratio of about 10: 1, absorb the primary moisture into loess, and put it in a rotary furnace (rotary furnace).

투입된 정수장 슬러지는 회전하는 회전식로 내부에서 이미 혼합되어진 황토로 인하여 덩어리로 뭉치는 현상을 낮게 할 수 있으며 회전식로 내부에서 고열로 인하여 수분 및 유기물이 증발되거나 소각되어 제거된다The injected sludge from the water purification plant can reduce the agglomeration due to the loess that is already mixed inside the rotary rotary furnace, and the water and organics are removed by evaporation or incineration due to the high heat inside the rotary furnace.

3) 유기물 및 수분이 제거된 정수장 슬러지는 분말 상태 또는 2-15mm 정도의 형태를 갖추게 되며 색상은 회색이나 붉은색이 혼합된 형태로 배출되게 된다3) The water purification plant sludge from which organic matter and water are removed has the form of powder or 2-15mm, and the color is discharged in the form of mixed gray or red color.

In order to do this, the third material must be mixed.

그 혼합 물질로 안정적인 원적외선 파장을 발생시키고 인체와 가장 가까운 파장을 발생 시키며 빛과 접촉하여 광 촉매의 효과가 탁월한 이산화티탄을 중량부 약 15% 그리고 기타 물질을 아래의 표와 같이 첨가하여 2차 로라 분쇄기에서 분쇄 및 혼합을 시키면 백색에 가까운 원적외선 방사체가 제조된다 <표3>The mixed material generates stable far-infrared wavelengths, the wavelength closest to the human body, and is in contact with light to add about 15% by weight of titanium dioxide, which is excellent in photocatalytic effect, and other materials as shown in the table below. When pulverized and mixed in a pulverizer, a near infrared emitter is produced.

이렇게 제조된 원적외선 방사체는 아래의 표 <4>와 같은 방사 에너지를 가지게 되며 이것을 혼합/포장하면 하나의 제품으로 완성되는 것이다The far-infrared radiator manufactured as described above has radiant energy as shown in Table 4 below, and when mixed / packed, it is completed as one product.

4) 이렇게 완성된 원적외선 방사체는 매우 미세한 분말 형태를 가지게 되기 때문에 산업 전반에 응용 분야가 넓다4) The far-infrared radiator thus completed has a very fine powder form, so the application field is wide in the industry.
