본 고안은 용광로 집진수의 페하(pH)를 측정하는 장치에 관한 것으로, 특히 용광로 집진수의 측정정밀도 향상과 수명연장성을 개선한 용광로 집진수의 페하측정장치에 관한 것이다.The present invention relates to a device for measuring the pH of the furnace dust collection, and more particularly, to a pH measurement device of the furnace dust collection that improves the measurement accuracy of the furnace dust collection and the life extension.

종래기술에 따른 용광로 집진수의 페하측정방식은 제1도에 도시된 바와같이, 수처리 설비(100)에서 용광로 집진수(105)가 흐르는 재처리조(110)의 내부에 페하측정센서(115)를 장착하고, 상기 페하측정센서(115)가 흐르는 집진수(105)에 접촉하여 지시부(120)로 측정값을 전달하여 표시하는 것이었다.In the conventional method of measuring the furnace dust collecting method, as shown in FIG. 1, the measuring instrument 115 is disposed inside the reprocessing tank 110 through which the furnace dust collecting 105 flows from the water treatment facility 100. Was installed, and the measured value was delivered to the indicator 120 in contact with the collecting dust 105 through which the pH measurement sensor 115 flowed and displayed.

그러나, 이와같은 종래의 방식은 다음과 같은 문제점이 있다.However, this conventional method has the following problems.

즉, 집진수중에 함유된 다량의 분진(dust) 성분을 침강시키기 위해 투입되는 응집제 성분이 집진수중에서 완전히 처리되지 못한 미분의 분진과 함께 혼합되어 페하측정센서(115)의 표면에 부착되고, 따라서 시간이 경과하면서 페하측정센서(115)의 표면에 스케일(Scale)이 형성되어 페하측정센서(115)의 표면이 피복(coating)되는 현상이 발생되어 정확한 페하측정이 곤란한 문제점을 갖는 것이었다.That is, the coagulant component introduced to sediment a large amount of dust components contained in the dust collector is mixed with the fine dust that has not been completely processed in the dust collector and adhered to the surface of the pH sensor 115. As time elapses, a scale is formed on the surface of the pH measuring sensor 115 and a phenomenon in which the surface of the pH measuring sensor 115 is coated occurs, which makes it difficult to accurately measure pH.

또한, 페하를 검지하고자 하는 집진수의 온도가 대략 70℃의 고온이면서 페하측정센서의 장착부위의 유속이 매우 빠르고, 장착부위의 구조상 불안정으로 인하여 페하측정센서의 수명이 단축되는 문제점을 갖는 것이었다.In addition, while the temperature of the dust collector to detect the pH is a high temperature of approximately 70 ℃, the flow rate of the mounting portion of the Peha measurement sensor is very fast, due to the structural instability of the mounting site has a problem that the life of the peha measurement sensor is shortened.

본 고안은 상기와 같은 종래의 문제점을 해소화기 위한 것으로서, 페하측정센서의 검지부에 스케일이 부착되는 것을 방지함으로써 페하검출수치의 정확도를 향상시키고, 페하측정센서가 정지된 상태의 집진수로부터 페하를 측정하도록 함으로서 페하측정센서의 파손을 방지하여 내구성을 향상시킨 용광로 집진수의 페하측정장치를 제공함에 그 목적이 있다.The present invention is to solve the above-mentioned conventional problems, to improve the accuracy of the pH detection value by preventing the scale from being attached to the detection unit of the pH measurement sensor, and to remove the pH from the dust collection state in which the pH measurement sensor is stopped. It is an object of the present invention to provide a furnace measuring device for collecting dust in a furnace that prevents damage of the measuring device by improving the durability.

상기 목적을 달성하기 위하여 본 고안은,The present invention to achieve the above object,

재처리조의 집진수가 자동개폐밸브를 갖춘 집진수유입관을 통해 페하측정조의 하부로 공급되고, 고온의 세척수가 자동개폐밸브를 갖춘 세척수공급관을 통해 상기 페하측정조의 상부로 공급되며, 상기 페하측정조는 자동개폐밸브를 갖춘 배수관을 하부에 설치한 중공형 몸체로 이루어지고, 상기 자동개폐밸브는 제어판넬에 의해 설정된 순서에 의해 개폐되며, 상기 페하측정조의 내측 상부에 집진수의 페하를 검출하기 위한 페하측정센서를 갖춘 페하측정장치에 있어서,The dust collection of the reprocessing tank is supplied to the lower part of the pH measuring tank through the dust collecting inlet pipe with the automatic opening and closing valve, and the high temperature wash water is supplied to the upper part of the pH measuring tank through the washing water supply pipe having the automatic opening and closing valve. It consists of a hollow body provided with a drain pipe with an on-off valve at the bottom, the automatic opening and closing valve is opened and closed in the order set by the control panel, and the phage measurement for detecting the drop of dust collection on the inner upper part of the pH measuring tank In the measuring device equipped with a sensor,

상기 세척수 공급관은 페하측정센서의 검지부 외표면에 근접하도록 연장형성되어 집진수유입관의 자동개폐밸브를 차단하고 배수관의 자동개폐밸브를 개방한 상태의 세척작업시 검지부에 세척수를 분사함을 특징으로 하는 용광로 집진수의 페하측정장치를 마련함에 의한다.The washing water supply pipe is extended to be close to the outer surface of the detection unit of the pH measurement sensor to block the automatic opening and closing valve of the dust collecting inlet pipe and to spray the washing water to the detection unit during the cleaning operation in the state of opening the automatic opening and closing valve of the drain pipe. It is to prepare the measuring device for the collecting of the furnace.

이하, 본 고안을 첨부된 도면에 따라서 보다 상세히 설명한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

제2도에는 본 고안에 따른 용광로 집진수의 페하측정장치(1)가 도시되어 있다.Figure 2 shows the peha measurement device 1 of the furnace dust collection according to the present invention.

상기 페하측정장치(1)는 내부에 집진수(105)가 담겨지는 중공형 몸체(5a)를 갖는 페하측정조(5)를 가지며, 상기 페하측정조(5)는 자동개폐밸브(7a)를 장착한 집진수유입관(7)을 통하여 재처리조에 연결된다. 그리고, 상기 페하측정조(5)는 하부 바닥면(5b)이 위는 넓고 아래로 갈수록 좁은 원추경사면을 형성하며, 그 중앙에는 자동개폐밸브(11a)를 장착한 배수관(11)이 형성된다. 또한, 상기 중공형 몸체(5a)의 측방에는 오버플로배관(overflow line)(13)이 인출되어 배수관(11)에 연결되는 구조를 갖는다.The lower measuring device 1 has a lower measuring tank 5 having a hollow body 5a in which a dust collector 105 is contained therein, and the lower measuring tank 5 has an automatic opening / closing valve 7a. It is connected to the reprocessing tank through the installed dust collecting inlet pipe (7). In addition, the lower measuring surface 5 has a lower conical surface 5b and a conical inclined surface becomes narrower downward, and a drain pipe 11 equipped with an automatic opening and closing valve 11a is formed at the center thereof. In addition, an overflow line 13 is drawn out to the side of the hollow body 5a to be connected to the drain pipe 11.

한편, 상기 페하측정조(5)의 내부에는 페하측정센서(115)가 장착되며, 이후에 설명될 제어판넬(20)에 전기적으로 연결되어 있다. 그리고, 상기 페하측정센서(115)로 세척수를 제공하기 위한 세척수공급관(25)이 갖추어지는바, 상기 세척수 공급관(25)은 자동개폐밸브(25a)를 갖추고, 고온의 세척수 주배관(미도시)에 일단부가 연결되며, 타단부는 페하측정센서(115)의 검지부(115a)에 근접한 하부에 위치된다. 따라서 자동개폐밸브(25a)의 열림작동으로 고온(대략 80℃)의 세척수가 페하측정센서(115)의 검지부(115a)로 분사될 수 있는 것이다.On the other hand, the inside of the pH measuring tank 5 is equipped with a pH measuring sensor 115, it is electrically connected to the control panel 20 to be described later. In addition, the washing water supply pipe 25 for providing the washing water to the pH measuring sensor 115 is provided, and the washing water supply pipe 25 is provided with an automatic opening / closing valve 25a, and the washing water main pipe (not shown) of high temperature. One end is connected, and the other end is located at the lower portion close to the detection unit 115a of the pH measuring sensor 115. Therefore, the washing water having a high temperature (approximately 80 ° C.) may be injected into the detection unit 115a of the pH measuring sensor 115 by the opening operation of the automatic opening / closing valve 25a.

또한, 제어판넬(20)은 내부에 PLC(Programmable Logic Controller)(미도시)와 타이머(Timer)(미도시) 등을 내장하고, 상기 자동개폐밸브(7a)(11a)(25a)에 전기적으로 연결되어 상기 자동개폐밸브(7a)(11a)(25a)를 미리 설정된 순서에 따라서 자동으로 개방 및 폐쇄시킬 수 있도록 구성되는 것이다. 그리고, 상기 제어판넬(20)에는 페하측정센서(115)에서 검출된 페하측정값이 표시(display)되는 계기판(22)이 장착되는 것이다.In addition, the control panel 20 has a programmable logic controller (PLC) (not shown) and a timer (Timer) (not shown) therein, and is electrically connected to the automatic opening / closing valves 7a, 11a, and 25a. Is connected to the automatic opening and closing valve (7a) (11a, 25a) is configured to automatically open and close in a predetermined order. In addition, the control panel 20 is equipped with an instrument panel 22 for displaying the measured value measured by the pH measuring sensor 115 (display).

상기와 같이 구성된 본 고안은, 용광로 집진수에서 페하값을 측정하고자 하는 경우, 먼저 제어판넬(20)에서는 집진수유입관(7)의 자동개폐밸브(7a)를 열고, 배수관(11)의 자동개폐밸브(11a)를 닫게 된다. 따라서 재처리조(110)에 위치된 집진수는 집진수유입관(7)을 통하여 페하측정조(5) 내부로 점차 차오르게 되고, 페하측정센서(115)에까지 도달하게 되면, 페하측정센서(115)에 의해서 연속적으로 페하가 검출되며, 점차 상승되어 오버플로배관(13)에까지 도달하면 오버플로배관(13)을 통하여 배수관(11)으로 흐르게 되는 것이다.When the present invention is configured as described above, if you want to measure the lower value in the blast furnace dust collection, first open the automatic opening and closing valve (7a) of the dust collection inlet pipe 7 in the control panel panel 20, automatic opening and closing of the drain pipe (11) The valve 11a is closed. Therefore, the dust collector located in the reprocessing tank 110 is gradually filled into the pH measuring tank 5 through the dust collecting inlet tube 7, and reaches the pH measuring sensor 115, when the pH measuring sensor 115 is reached. Peh is continuously detected by), and gradually rises to reach the overflow pipe 13 and flows to the drain pipe 11 through the overflow pipe 13.

이때, 페하측정센서(115)에서 검출된 페하값은 제어판넬(20)의 계기판(22)에 연속적으로 표시되고, 제어판넬(20)에 내장된 타이머(미도시)가 일정시간을 게수(count)하면, 상기 집진수 유입관(7)의 자동개폐밸브(7a)는 닫히고, 배수관(11)의 자동개폐밸브(11a)는 열려서 페하측정조(5) 내부의 집진수는 외부로 배출된다. 그리고, 상기 세척수 공급관(25)의 자동개폐밸브(25a)는 열리게 되고, 고온(대략 80℃)의 세척수가 페하측정센서(115)의 검지부(115a)로 분사되어 검지부(115a)의 표면에 부착된 응집제 성분과 분진(dust) 등을 세척 제거시키는 것이다. 또한, 이와같은 세척작동은 제어판넬(20)에 내장된 세척용 타이머에 설정된 시간에 이르면 멈추게 되고, 다시 집진수 유입관(7)의 자동개폐밸브(7a)는 열리며, 배수관(11)의 자동개폐밸브(11a)는 닫히게되어 집진수의 페하측정작업이 재개되는 한편, 이러한 페하측정작업과 세척작업은 반복적으로 계속 이루어지는 것이다.At this time, the pH value detected by the pH measuring sensor 115 is continuously displayed on the instrument panel 22 of the control panel 20, and a timer (not shown) built in the control panel 20 counts a predetermined time. ), The automatic opening / closing valve 7a of the dust collecting inlet pipe 7 is closed, and the automatic opening / closing valve 11a of the drain pipe 11 is opened so that the dust collecting inside the measuring tank 5 is discharged to the outside. Then, the automatic opening and closing valve 25a of the washing water supply pipe 25 is opened, and washing water at a high temperature (approximately 80 ° C.) is sprayed to the detecting unit 115a of the measuring sensor 115 and attached to the surface of the detecting unit 115a. To remove and remove the coagulant component and dust. In addition, such a washing operation is stopped when the time set in the washing timer built in the control panel 20, the automatic opening and closing valve (7a) of the dust collecting inlet pipe 7 is opened, the drain pipe 11 of The automatic opening / closing valve 11a is closed so that the measuring operation for collecting dust is resumed, while the measuring operation and washing are repeatedly performed.

따라서, 본 고안은 페하측정센서가 집진수의 페하를 측정한 다음 세척수로서 응집제와 분진을 항상 세척하기 때문에 정확한 페하측정이 가능하게 된다.Therefore, the present invention enables accurate measurement of pH because the pH sensor measures the pH of the dust collected and then always washes the flocculant and the dust as washing water.

또한, 페하측정센서는 페하측정조내에 담겨진 집진수에서 페하를 측정함으로서 페하측정센서에는 아무런 외부 힘이 가해지지 않음으로서 파손이 방지되어 내구성이 향상되며, 페하측정센서가 재처리조에서 분리된 페하측정조에 장착되기 때문에 정비 및 설비관리가 용이한 실용상의 효과를 얻는 것이다.In addition, by measuring the pH from the dust collection in the pH measuring tank, the pH measuring sensor does not apply any external force to the pH measuring sensor to prevent damage and improve durability, and the pH measuring sensor is separated from the reprocessing tank. Since it is installed in the measuring tank, the practical effect is easy to maintain and manage the equipment.
