본 고안은 중금속계, 알카리계 (CN), 하이포계 (사진정착 및 현상액)등의 각종 유해물질이 고농도로 혼합 함유된 각종 산업폐수나 액상의 폐기물을 건조 처리함에 있어서 농축기에서 농축된 폐수를 가열드럼에 의해 효과적으로 증발, 건조시켜서 유해물질(슬러지)의 효율적인 케이크화를 이루도록 하므로서 슬러지의 부피를 최대한 감소시켜 폐수처리 효율을 증대시킬수 있도록 한 고안에 관한 것이다.The present invention heats the wastewater concentrated in the concentrator in the drying treatment of various industrial wastewater or liquid waste containing high concentrations of various harmful substances such as heavy metals, alkalis (CN), hypo-types (photo fixing and developer) The present invention relates to a device designed to increase the efficiency of wastewater treatment by reducing the volume of sludge as much as possible by efficiently evaporating and drying the drum to achieve efficient cake formation of harmful substances (sludge).

종래에는 순환되는 이송벨트에 의해 이송되는 피건조물을 가옅드럼에 밀착시켜 건조한 다음 가열드럼에 부착된 건조슬러지를 스크렙퍼로 떼어내도록 장치(일본 실용신안공보 소60-18799호)가 있었으나 이는 피건조물이 폐수와 같이 액상태 일때에는 이송벨트로 폐수를 가열드럼에 이송밀착 시키기가 힘들어 사용이 어려운점과 장시간 사용시 이송벨트가 잘 이완되므로 이를 수시로 조절하여야 함은 물론 순환되어야 하는 이송벨트 때문에 몸체가 필요이상 커져야 하는 폐단이 있으며, 또한 액상원료가 일정깊이로 채워지는 진공실내에 발열 원판을 수개 축설하여 된 건조장치 (일본 특허공보 소55-5632호)가 있으나 이는 발열 원판의 주면에 액상원료가 부착되게 하기위해 발열 원판의 일단이 액상원료에 잠겨진 상태에서 저속으로 회전되는 것이기 때문에 저온의 액상원료에 잠겨진 부분의 온도가 액상원료에 열을 급속히 빼앗겨 저온으로 떨어졌다가 다시 고온으로 가열되어야 함에 따라 주면에 부착된 액상원료의 증발 건조 효율이 떨어지게 되는 폐단이 있었다.Conventionally, there was a device (Japanese Utility Model Publication No. 60-18799) to dry the dried material transported by the circulating conveying belt to a light drum, and then remove the dry sludge attached to the heating drum with a scraper. In the liquid state like this wastewater, it is difficult to transfer the wastewater to the heating drum with a conveying belt, which makes it difficult to use and the conveying belt relaxes well for a long time. There is a drying device (Japanese Patent Publication No. 55-5632) in which several heating plates are laid in a vacuum chamber in which the liquid raw material is filled to a certain depth. However, it is attached to the main surface of the heating plate. In order to ensure that one end of the heating disc is rotated at a low speed while immersed in the liquid raw material There was a closed end that evaporation efficiency of the liquid material attached to the principal surface, as the temperature of the part submerged in the liquid raw material of a low temperature has dropped to a low temperature rapidly deprived of heat to the liquid raw material to be re-heated to a high temperature drops.

본 고안은 이와같은 점을 감안하여 창안된 것으로서 이를 첨부된 도면에 의해 상세히 설명하면 다음과 같다.The present invention was created in view of the above, and described in detail by the accompanying drawings as follows.

건조실(1)내의 상하부에 가열드럼(2)과 폐수조(3)를 설치함에 있어서 가열드럼(3)을 폐수조(3)의 폐수 수면(4)과 약간 떨어지도록 축설하고 그 일측에는 날개(6)가 환설된 임펠러(5)를 일단이 폐수속에 잠겨지도록 축설하며 가열드럼(2)의 저면에는 교반기(7)가 왕복운동 하도록 설치하여 된 것으로서 도면중 미설명 부호 (8)은 스크렙퍼이고, (9)는 슬러지 케이크(10)의 낙하 안내통이며 (11)은 교반기 (7)를 왕복작동 시켜주는 캠이고, (12)는 슬러지 케이크(10)의 수집함이며 (13)은 가열드럼(2)의 축이고 (14)는 캠레버이다.In installing the heating drum 2 and the waste water tank 3 in the upper and lower parts of the drying chamber 1, the heating drum 3 is arranged so as to be slightly separated from the waste water surface 4 of the waste water tank 3, and at one side thereof, a wing ( 6) is installed so that one end is immersed in the waste water and the stirrer 7 is reciprocated on the bottom of the heating drum 2, and reference numeral 8 in the figure is a scraper. (9) is a drop guide cylinder of the sludge cake (10), (11) is a cam for reciprocating the stirrer (7), (12) is a collection of sludge cake (10) and (13) is a heating drum The axis of (2) and (14) are cam levers.

이와같이 형성된 본 고안은 1m3인 폐수를 농축기에서 0.2-1m3미만으로 농축하여된 폐수가 건조실(1)의 폐수조(3)에 유입된후 캠(11)에 의해 교반기(7)가 왕복운동을 하면 폐수속에 함유된 중금속 등의 슬러지가 폐수조(3) 바닥에 침전되지 않고 폐수에 골고루 섞여있는 상태를 효과적으로 유지하게 된다.Thus formed the subject innovation is a reciprocating stirrer (7) by the cam (11) after the waste water is concentrated to less than 3 0.2-1m a 1m 3 of waste water from the concentrator enters the waste water tank 3 of the drying chamber (1) When the sludge such as heavy metals contained in the waste water is not precipitated at the bottom of the waste water tank (3), it is effectively maintained evenly mixed in the waste water.

이러한 상태에서 폐수속에 일단이 잠겨있는 임펠러(5)가 회전하면 임펠러(5)에 환설된 날개(6)들이 교반기(7)에 의해 슬러지가 골고루 섞여있는 고농도의 폐수를 쳐올려 회전되는 가열드럼(2)의 저면에 뿌려주게 되며 이와같이 저면에 고농도의 폐수가 계속 부착되는 가열드럼(2)은 종래와 같이 폐수속에 일단이 잠겨진 상태로 회전되는 것이 아니고 폐수조(3)의 폐수 수면(4)과 떨어진 상태에서 회전되므로 가열드럼(2)은 고온으로 가열된 상태를 거의 그대로 유지할수 있어 외주면에 부착된 폐수의 증발 건조효율이 매우 뛰어나게 되는 것이다.In this state, once the impeller 5 is locked in the waste water flow, the heating drum rotates by lifting up the high concentration of wastewater in which sludge is mixed evenly by the agitator 7 with the wings 6 rotated in the impeller 5. 2) the heating drum (2) which is sprinkled on the bottom of the wastewater is attached to the bottom of the wastewater tank (3) rather than being rotated in a state where one end is immersed in the wastewater container as in the prior art. Since the rotating drum 2 can be maintained in a state of being heated at a high temperature as it is rotated apart, the evaporation drying efficiency of the wastewater attached to the outer circumferential surface is very excellent.

그리고 이와같이 수분이 효율적으로 증발 건조됨에 따라 슬러지 케이크(10)의 부피는 최대한 줄어들게 되며 이에따라 통상의 장치와 같이 스크렙퍼(8)에 의해 가열드럼(2)으로부터 분리되어 수집함(19)에 수거되는 슬러지 케이크(10)의 양은 폐수조(3)에 유입되는 폐수의 양에 비해 현저히 적은량으로 감소되어 수거되므로 운반 및 폐기처리 하기가 용이하게 되는 것이다.As the water is efficiently evaporated and dried in this manner, the volume of the sludge cake 10 is reduced as much as possible, and thus is separated from the heating drum 2 by the scraper 8 and collected in the collecting 19, as in a conventional apparatus. Since the amount of the sludge cake 10 is reduced and collected in a significantly smaller amount than the amount of wastewater introduced into the wastewater tank 3, the sludge cake 10 is easily transported and disposed of.

이러한 본 고안은 교반기(7)의 왕독운동을 캠(11) 대신 실린더등의 기계적 장치로 대체할수 있고 가열드럼의 열원으로는 전열코일이나 또는 스팀등의 간접열을 이용할수 있으며 가열드럼의 온도에 따라 오염물질 및 폐수의 성상에 따른 슬러지 케이크의 함수율을 조정할수있고 건조되는 동안 저비등점 물질 및 공비 효과에 의해 일부 대기오염 물질이 기화되므로 환경오염 방지의 효과도 있는 것으로서 본 고안은 폐수의 성상이 여러가지 혼합되어 있거나 고농도인 경우, 물리화학적 및 생물학적 처리가 거의 불가능한 경우에 화학적 반응이 일어나지 않도록 유지하면서 폐수를 증발, 건조하여 슬러지 케이크의 부피를 최대한 감소시키므로서 폐기효율을 증대시키는 효과가 있는 것이다.The present invention can replace the reading movement of the stirrer 7 with a mechanical device such as a cylinder instead of the cam 11, and indirect heat such as a heat transfer coil or steam can be used as a heat source of the heating drum. Therefore, the water content of the sludge cake according to the contaminants and waste water properties can be adjusted, and some air pollutants are vaporized by low boiling point material and azeotropic effect during drying. In the case of various mixed or high concentrations, the waste water is evaporated and dried to minimize the volume of the sludge cake while increasing the efficiency of waste disposal while maintaining the chemical reaction in a case where physicochemical and biological treatment is almost impossible.
