본 발명은 폐열이나 스팀의 열을 전열판을 통해 원액에 전달되도록 하여 원액을 증발 농축하면서 원액중의 용존고형물을 석출, 건조하여 분리배출하는 증발농축건조장치에 관한 것으로서, 좀더 상세하게는 곡면형 전열판을 동일반경으로 조립하여 형성한 원통형의 전열부재를 회전축의 중심에서 직경을 달리하며 다수 형성한 전열수단을 회전 교반작동케 구성하므로 동체를 컴팩트하게 유지하면서 전열면적을 증대 및 전열효과를 극대화하고, 상기 전열수단의 전열판 표면으로 형성된 다수의 장홈으로 원액의 회전 교반시 강한 난류 형성 및 회전속도 조절에 의해 전열면의 스케일 형성을 효과적으로 방지하는 원통형 전열판을 이용한 증발농축건조장치에 관한 것이다.The present invention relates to an evaporative concentration drying apparatus for depositing, drying, and discharging dissolved solids in a stock solution by transferring the waste heat or steam heat to the stock solution through a heat transfer plate, and evaporating and concentrating the stock solution. The cylindrical heat transfer member formed by assembling the same radius has a different diameter at the center of the rotating shaft, and a plurality of heat transfer means are formed by rotating stirring operation, thereby increasing the heat transfer area and maximizing the heat transfer effect while maintaining the body compact. It relates to an evaporative concentration drying apparatus using a cylindrical heat transfer plate effectively prevents the formation of scale of the heat transfer surface by forming a strong turbulence and rotational speed during rotation stirring of the stock solution into a plurality of long grooves formed on the heat transfer plate surface of the heat transfer means.

일반적으로 용액(원액)으로부터 용존고형물을 석출, 건조하는 건조분리방법은, 1단계로서 용액(원액)을 증발농축장치에 유입하여 스팀으로 다량의 원액을 증 발시켜 용존고형물의 농도가 높게 되는 농축액을 형성하여 배출하고, 2단계로는 상기 농축액을 별도의 석출장치나 건조장치를 거쳐 잔여 수분을 증발시켜 고액분리를 이루게 되는 것이다.In general, the dry separation method of depositing and drying dissolved solids from a solution (stock solution) is a concentrated solution in which the solution (stock solution) is introduced into the evaporation concentrator as a first step and a large amount of the stock solution is evaporated with steam to increase the concentration of the dissolved solids. Forming and discharging, in the second step is to achieve a solid-liquid separation by evaporating the residual moisture through a separate precipitation apparatus or drying apparatus.

즉, 종래의 용액(원액)을 건조분리하는 방법은 용액(원액)으로 부터 다량의 수분을 증발시키기 위해 다수의 전열면적을 갖는 투 관형열교환기가 설치된 증발농축장치와, 석출 및 건조를 위한 별도의 석출, 건조장치가 요구되었다.That is, the conventional method of dry separation of the solution (stock solution) is an evaporation concentrator equipped with a tubular heat exchanger having a plurality of heat transfer areas for evaporating a large amount of water from the solution (stock solution), and a separate separation for precipitation and drying A precipitation and drying device was required.

그런데 상기한 용액(원액)로 부터 용존고형물을 석출, 건조하는 종래의 방법은 증발농축장치와 석출,건조장치를 별도 구비함에 따라 설비비용 및 그 공간활용성이 저하되는 문제점이 있었다.However, the conventional method of depositing and drying the dissolved solids from the above solution (stock solution) has a problem in that the installation cost and space utilization are lowered by separately providing the evaporation concentrating device and the precipitation and drying device.

또한, 상기 용액(원액)의 증발농축 과정에서 과도한 농축으로 용존고형물이 석출될 경우에 전열관의 오염이 급격히 진행되어 전열면으로 과도한 스케일이 고착되거나 전열관이 폐색되어 증발농축 효율이 급격히 저하되거나 불가능하게 되는 문제점이 있었다.In addition, when the dissolved solids precipitate due to excessive concentration in the evaporative concentration of the solution (stock solution), the contamination of the heat pipe rapidly progresses and excessive scale adheres to the heat transfer surface, or the heat pipe is blocked, so that the evaporation concentration efficiency is rapidly reduced or impossible. There was a problem.

또한, 상기 전열관이 관판에 고정설치되어 있기 때문에 전열면에 과도한 스케일의 고착이나 폐색, 전열면의 침,부식등으로 인한 부분 교체나 보수가 곤란한 비 경제적인 문제점이 있었다.In addition, since the heat transfer pipe is fixed to the tube plate, there is an uneconomical problem in that it is difficult to replace or repair parts due to excessive scale fixation or blockage on the heat transfer surface, needles on the heat transfer surface, and corrosion.

따라서, 종래에는 증발농축장치는 용액(원액)의 용존고형물의 농도가 높을 경우나 다양한 성상의 용존물질이 혼합되어 있는 경우에는 고농축 및 건조분리방법으로 적용하기가 어려워 대부분 저농도 용액의 저농축용으로 사용이 제한되고 있었다. Therefore, conventionally, the evaporation concentrator is difficult to apply by high concentration and dry separation method when the concentration of dissolved solids in solution (stock solution) is high or when mixed substances of various properties are mixed. Use was limited.

이러한 문제점을 개선하고자 상기 농축액이나 고농도용액의 농축 및 건조에 적합한 증발농축건조장치를 본 출원인에 의해 실용신안등록 제20-227278호 등에 개시된 바 있다.In order to improve this problem, an evaporation concentration drying apparatus suitable for concentrating and drying the concentrate or high concentration solution has been disclosed by the present applicant in Utility Model Registration No. 20-227278.

이는 외면에 스팀재킷이 설치되고, 내부에 교반장치가 부착된 증발농축실과건조실을 상하로 형성하여 증발 및 건조공정을 단일의 장치에서 행함은 물론 고형원액의 스케일을 제거하여 전열면을 청결하게 유지하도록 한 것이었다.The steam jacket is installed on the outer surface, and the evaporation concentration chamber and the drying chamber are formed up and down with a stirring device inside. The evaporation and drying process is performed in a single device, and the scale of the solid stock solution is removed to keep the heat transfer surface clean. It was to be.

그러나 상기한 장치는 전열면적이 스팀재킷의 설치된 부분으로 제한되기 때문에 전열용량이 제한되고, 이 전열용량을 높이기 위해 전열면적을 키울 경우 건조기의 크기가 비대해져야 하므므로 대용량의 건조처리에 한계를 갖는 문제점이 있었다.However, since the heat transfer area is limited to the installed portion of the steam jacket, the heat transfer capacity is limited, and if the heat transfer area is increased to increase the heat transfer capacity, the size of the dryer must be enlarged, which limits the drying process. There was a problem.

또한, 상기 전열면으로 용존고형물의 스케일이 여전히 고착되거나 침,부식 등이 발생되는 문제와, 이로인해 전열면이 손상되는 경우에 전열수단 전체를 교체해야하는 비 효율적인 문제점이 있었다.In addition, there is a problem that the scale of the dissolved solid is still fixed to the heat transfer surface or acupuncture, corrosion and the like, and there is an inefficient problem to replace the entire heat transfer means when the heat transfer surface is damaged.

본 발명은 상기와 같은 종래기술 및 본 출원인에 의해 선 출원된 기술이 갖는 문제점을 해결하기 위하여 안출된 것으로서, 동체 내부에 많은 전열면적을 제공함과 상기 전열면적을 회전 교반하면서 전열효과를 극대화하므로 컴팩트한 크기에서 대량의 고농도용액을 효과적으로 처리하도록 제공함에 그 목적이 있다.The present invention has been made to solve the problems of the prior art and the prior application by the present applicant, and provides a large heat transfer area inside the body and maximizes the heat transfer effect while rotating stirring the heat transfer area is compact Its purpose is to provide effective treatment of large concentrations of solution at one size.

본 발명은 용액의 농도에 따라 전열판의 회전속도를 조절하여 동체 내부의 용액(원액)의 강한 난류를 형성하거나 전열판의 회전속도를 조절하므로 유속의 변화를 주므로 전열면으로 스케일의 생성을 제어하거나 전열효율을 극대화하는데 그 목적이 있다.The present invention forms a strong turbulence of the solution (stock solution) inside the fuselage by adjusting the rotational speed of the heating plate according to the concentration of the solution or adjusts the rotational speed of the heating plate, so that the flow rate is changed to control the generation of the scale by the heating surface or The purpose is to maximize the thermal efficiency.

본 발명은 농도관리 실패로 인해 전열판으로 과도한 스케일형성 또는 전열판 폐색 등의 손상이 발생되는 경우에 손상된 전열판만을 용이하게 수리 또는 분리 교체하도록 하므로서 경제성을 극대화하는데 그 목적이 있다.The present invention has an object of maximizing economic efficiency by easily repairing or separating and replacing only a damaged heating plate when damage such as excessive scale formation or occlusion of the heating plate occurs due to the failure of concentration control.

Of course, it can be modified to combine.

또한, 상기 전열수단(100)을 구성하는 각 전열판(21,21',21"...)은 전열 표면에 다수의 장홈(50)을 상하로 경사를 이루고 좌우로 대칭되게 형성하여 전열판이 회전 교반시에 전열판의 표면에서 용액이 난류를 형성하도록 구성된다.In addition, each of the heat transfer plate (21, 21 ', 21 "...) constituting the heat transfer means 100 forms a plurality of long grooves 50 on the heat transfer surface inclined up and down and symmetrically from side to side to rotate the heat transfer plate.

미설명부호로서, 120은 회전축(103)을 동체(101)의 상하부에서 지지하는 베어링, 104는 회전축(103)의 상하부를 차단하는 차단막을 각각 나타내는 것이다.Reference numeral 120 denotes a bearing for supporting the rotary shaft 103 at the upper and lower portions of the body 101, and 104 denotes a blocking film for blocking the upper and lower portions of the rotary shaft 103.

다음은 상기와 같이 구성되는 본 발명의 작동 및 작용에 대해 설명하기로 한다.Next will be described the operation and action of the present invention configured as described above.

먼저, 낮은 온도에서 수분(물)을 증발시키기 위해 진공펌프(150)를 통하여 동체(101) 내부에 약 150torr 정도의 진공이 형성되게 한다.First, a vacuum of about 150 torr is formed inside the body 101 through the vacuum pump 150 to evaporate water (water) at a low temperature.

상기 동체(101)의 내부에 진공이 형성되면, 원액이송펌프(160)가 가동되어 공급밸브가 열리면서 원액은 원액유입구(114)를 통해 동체(101) 내부에 공급된다.      When the vacuum is formed in the body 101, the feed solution transfer pump 160 is operated to open the supply valve and the feed solution is supplied into the body 101 through the feed inlet 114.

이와 같이하여 상기 원액 공급이 상기 동체(101)의 측단에 설치된 액면계(109)까지 이루어지면, 공급밸브가 닫히고 구동모터(110)가 서서히 구동되면서 원액은 회전축(103)에 설치된 전열수단(100)의 회전교반에 따라 회전교반된다.      In this way, when the raw liquid supply is made up to the liquid level gauge 109 installed at the side end of the body 101, the supply valve is closed and the driving motor 110 is gradually driven while the raw liquid is transferred to the heating shaft 103. It is rotated by rotating stirring.
