Description

샤프트킬른 배가스의 이차 제진장치{Apparatus for secondary dedusting of exhausted gas from shaft kiln}Apparatus for secondary dedusting of exhausted gas from shaft kiln}

본 발명은 샤프트킬른에서 배출되는 배가스를 이차 제진하는 샤프트킬른 배가스 제진장치에 관한 것으로, 특히 샤프트 킬른에서 배출되어 일차로 벤튜리 스커러버에서 제진된 배가스를 집진수를 이용하여 이차 제진하는 샤프트킬른 배가스 제진장치에 관한 것이다.The present invention relates to a shaft kiln exhaust gas vibration suppression apparatus for secondaryly dedusting exhaust gas discharged from a shaft kiln. In particular, the shaft kiln exhaust gas discharged from the shaft kiln and firstly dedusted from the venturi scrubber by dust collecting is used. It relates to a vibration damper.

일반적으로 샤프트킬른은 도 1에 도시된 바와 같이 두개의 노로 구성되어 서로 교차되면서 생석회를 소성시킨다.In general, the shaft kiln is composed of two furnaces as shown in Figure 1 to cross each other to fire quicklime.

이러한 샤프트킬른(10)에서 배출되는 배가스를 집진하는 벤튜리 스크러버(12)는 습식 제진기의 일종으로서 배가스덕트(14)로부터 공급된 배가스에 집진수를 분사하여 분진이 제거되도록 하므로 집진효율을 높이고, 미세분진의 제거가 용이토록 하였다.Venturi scrubber 12 for collecting the exhaust gas discharged from the shaft kiln 10 is a kind of a wet vibration suppressor to inject dust to the exhaust gas supplied from the exhaust gas duct 14 to remove dust, thereby increasing the dust collection efficiency, It was easy to remove fine dust.

특히 폭발성이나 부식성이 있거나, 고온의 분진인 경우는 여과 집진기나 전기 집진기 등의 사용의 어려우므로 벤튜리 스크러버(12)가 유용하게 사용된다.Especially in the case of explosive, corrosive or high temperature dust, the venturi scrubber 12 is useful because it is difficult to use such as a dust collector or an electrostatic precipitator.

이러한 벤튜리 스크러버(12)는 도 2에 도시된 바와 같이 가스통로인 벤튜리부분(16)은 그 단면이 점점 축소되다가 목부분을 지나면서 다시 확장되어 원래의 단면크기를 유지하게 된다.The venturi scrubber 12 is a gas passage venturi portion 16 as shown in Figure 2 is gradually reduced in cross-section crosses through the neck to maintain the original cross-sectional size.

또한 일정한 간격으로 집진수공급배관(18)이 설치되고, 이 집진수공급배관(18)을 통해 집진수를 주입시키면 벤튜리부분(16)의 수렴부분에서 유체의 운동에너지가 증가하여 정압력이 감소하고 유속이 증가하여 집진수가 분무화되고, 분무화된 집진수는 관성충돌을 일으켜 더스트를 효율적으로 제진하게 된다.In addition, the dust collecting supply pipe 18 is installed at regular intervals, and when the dust collecting is injected through the collecting dust supply pipe 18, the kinetic energy of the fluid increases in the converging portion of the venturi portion 16, so that the static pressure is increased. The dust is reduced and the flow rate is increased to atomize the dust, and the sprayed dust causes an inertial collision to efficiently dust the dust.

따라서 벤튜리 스크러버(12)의 내부 압력차가 증대될수록 제진 효율은 증가한다.Therefore, as the internal pressure difference of the venturi scrubber 12 increases, the damping efficiency increases.

그러나 제진효율의 향상을 위하여 압력차를 증가시킬수록 내부압력이 상승하게 되어 생산성이 저하되며, 제진효율의 증가폭이 점점 감소하는 문제점이 있다.However, as the pressure difference is increased to increase the vibration damping efficiency, the internal pressure is increased, resulting in a decrease in productivity, and an increase in the damping efficiency gradually decreases.

또한 배가스 중 분진의 입자가 미세할수록 집진수와 충돌할 수 있는 확률이 줄어들어 분진이 제거되지 못하여 환경을 오염시키는 문제점이 있다.In addition, the finer the particles of the dust in the exhaust gas has a problem of reducing the probability of colliding with the dust collection, the dust can not be removed to contaminate the environment.

본 발명은 상기의 문제점을 해결하기 위하여 안출된 것으로, 벤튜리부의 압력차를 증대시키지 않고도 제진효율을 향상시키고 미세분진도 제거할 수 있는 샤프트킬른 배가스의 이차 제진장치를 제공하는 데 목적이 있다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a secondary dust removal device for shaft kiln exhaust gas that can improve dust removal efficiency and remove fine dust without increasing the pressure difference of the venturi portion.

본 발명에 따른 샤프트킬른 배가스의 이차 제진장치는 일차로 제진된 배가스를 흡입하는 흡입부와, 배가스에 세정액을 공급하여 이차로 제진하는 세정부로 이루어진다.The secondary vibration suppression apparatus of the shaft kiln exhaust gas according to the present invention comprises a suction part for sucking the exhaust gas firstly damped, and a cleaning part for supplying the cleaning liquid to the exhaust gas to remove the secondary dust.

흡입부는 벤튜리 스크러버(12)와 연통되는 스크러버(13), 스크러버(13)의 스택(20) 일측에 연통 설치되는 데미스터(Demister; 22)와 제진된 배가스를 흡입하도록 연통 설치되는 블로워(Blower; 24)로 이루어진다.The suction unit is a blower (Blower) in communication with the venturi scrubber (12), the blower (Demister; 22) which is installed in communication with one side of the stack 20 of the scrubber (13) and the exhausted exhaust gas is installed 24).

여기서 스크러버(13)의 스택(20)과 블로워(24) 사이에는 흡입배관(26)이 연통 설치되고, 이 흡입배관(26)에 더스트를 제거하는 데미스터(22)가 설치된다.Here, the suction pipe 26 communicates with the stack 20 of the scrubber 13 and the blower 24, and a demister 22 for removing dust is provided in the suction pipe 26.

흡입배관(26)은 중공의 파이프로 흡입배관(26)에 흐르는 배가스의 유량을 조절하기 위하여 유량조절댐퍼(28)가 설치되는 것이 바람직하다.The suction pipe 26 is a hollow pipe is preferably provided with a flow control damper 28 to adjust the flow rate of the exhaust gas flowing in the suction pipe 26.

데미스터(22)는 흡입배관(26)을 통하여 배가스가 접선방향을 따라 유입되도록하여 싸이클론 원리에 따라 가스와 슬러리로 분리되도록 하며, 이 때 분리된 슬러리는 하부로 배출되고 분리된 가스는 상부로 올라가 배출되도록 한다.The demister 22 allows exhaust gas to flow along the tangential direction through the suction pipe 26 to be separated into a gas and a slurry according to the cyclone principle. To be discharged.

세정부는 블로워(24)에서 배출되는 배가스를 분배하는 헤더배관(30), 헤더배관(30)에 다수개 연통 설치되는 스파져(32), 스파져(32)에 세정액을 공급하는 세정액공급배관(34), 스파져(32)의 선단 전방에 설치된 콘(36)으로 이루어진다.The cleaning unit includes a header pipe 30 for distributing exhaust gas discharged from the blower 24, a sparger 32 installed in a plurality of communication lines in the header pipe 30, and a cleaning liquid supply pipe for supplying a cleaning liquid to the sparger 32. And a cone 36 provided in front of the tip of the sparger 32.

헤더배관(30)은 블로워(24)에서 배가스가 배출되는 배기배관(38)의 선단에 분지되어 설치된다.The header pipe 30 is branched at the tip of the exhaust pipe 38 through which exhaust gas is discharged from the blower 24.

여기서 배기배관(38)에는 배기배관(38)에 흐르는 배가스의 흐름을 제어하기 위한 배가스차단밸브(40)가 설치된다.Here, the exhaust pipe 38 is provided with an exhaust gas cutoff valve 40 for controlling the flow of the exhaust gas flowing in the exhaust pipe 38.

스파져(32)는 헤더배관(30)에 연통 설치되어 헤더배관(30)의 내부에 공급된 배가스를 스크러버(13)의 내부로 유입시킨다.The sparger 32 communicates with the header pipe 30 so that the exhaust gas supplied into the header pipe 30 is introduced into the scrubber 13.

세정액공급배관(34)은 선단이 스파져(32)의 내부에 위치하여 공급원으로부터 공급받은 세정액을 스파져(32)에 공급하게 된다.The cleaning solution supply pipe 34 has a tip located inside the sparger 32 to supply the cleaning solution supplied from the supply source to the sparger 32.

여기서 세정액공급배관(34)에는 솔레노이드밸브(42)가 설치되어 세정액공급배관(34)에 흐르는 세정액의 흐름을 개폐시킨다.The solenoid valve 42 is installed in the cleaning liquid supply pipe 34 to open and close the flow of the cleaning liquid flowing through the cleaning liquid supply pipe 34.

콘(36)은 스크러버(13)의 내부에 형성되며 스파져(32)로부터 배가스가 포함된 세정액이 공급되어 충돌하면서 제진된다.The cone 36 is formed inside the scrubber 13 and is supplied with a cleaning liquid containing exhaust gas from the sparger 32 to be damped while colliding.

한편 콘(36)의 하부에는 세정액이 배출되는 홀이 형성되고 이 홀을 통하여 배출되는 세정액은 재순환되는 것이 바람직하다.Meanwhile, a hole through which the cleaning liquid is discharged is formed in the lower portion of the cone 36, and the cleaning liquid discharged through the hole is preferably recycled.

한편 흡입부와 세정부를 제어하는 제어수단은 스크러버(13)의 스택(20)에 설치되는 더스트측정센서(44)와, 더스트측정센서(44)에 전달된 신호에 따라 흡입부 및 세정부를 제어하는 제어패널(50)로 이루어진다.Meanwhile, the control means for controlling the suction unit and the cleaning unit includes the dust measurement sensor 44 installed in the stack 20 of the scrubber 13 and the suction unit and the cleaning unit according to the signal transmitted to the dust measurement sensor 44. It consists of a control panel 50 for controlling.

더스트측정센서(44)는 스택(20)에 설치되어 스택(20)을 통하여 외부로 배출되는 배가스의 분진농도를 측정하게 된다.The dust measurement sensor 44 is installed in the stack 20 to measure the dust concentration of the exhaust gas discharged to the outside through the stack 20.

제어패널(50)은 더스트측정센서(44)에서 전달된 배가스농도 신호를 연산하여 유량조절댐퍼(28), 블로워(24), 솔레노이드밸브(42) 및 배가스차단밸브(40)의 작동을 제어한다.The control panel 50 calculates an exhaust gas concentration signal transmitted from the dust measurement sensor 44 to control the operation of the flow control damper 28, the blower 24, the solenoid valve 42, and the exhaust gas shutoff valve 40. .

즉, 더스트측정센서(44)에서 전달된 배가스 더스트농도가 설정치 이상이면 유량조절댐퍼(28)의 개도를 크게하여 유량을 증가시키며 더스트농도가 설정치 이하이면 유량조절댐퍼(28)의 개도를 작게하여 유량이 줄어들도록 한다.That is, if the exhaust gas dust concentration transmitted from the dust measurement sensor 44 is greater than or equal to the set value, the flow rate is increased by increasing the opening degree of the flow regulating damper 28, and if the dust concentration is less than or equal to the set value, the opening degree of the flow regulating damper 28 is made small. Allow the flow to decrease.

또한 제어패널(50)은 샤프트킬른(10)이 비소성 중일때는 배가스차단밸브(40)를 폐쇄하여 배가스의 유입을 막고, 세정액공급배관(34)의 솔레노이드밸브(42)를 개방하여 세정액을 공급하므로 스파져(32)의 내부가 세정되도록 제어한다.In addition, the control panel 50 closes the exhaust gas shutoff valve 40 to prevent the inflow of exhaust gas when the shaft kiln 10 is non-fired, and opens the solenoid valve 42 of the cleaning liquid supply pipe 34 to supply the cleaning liquid. Therefore, the inside of the sparger 32 is controlled to be cleaned.

여기서 제어패널(50)은 샤프트킬른(10) 구동프로그램에 따라 소성 및 비소성이 교차되어 작동하도록 제어하는 것이 바람직하다.In this case, the control panel 50 is preferably controlled so that the firing and non-firing cross work according to the shaft kiln 10 drive program.

이하, 본 발명에 따른 샤프트킬른 배가스의 이차 제진장치의 작동을 설명하면 다음과 같다.Hereinafter, the operation of the secondary vibration suppression apparatus of the shaft kiln exhaust gas according to the present invention.

두개의 노로 구성된 샤프트킬른(10)은 일측은 생석회를 소성을 시키고, 타측은 생석회를 소성시키지 않고 배가스를 배출시킨다.Shaft kiln 10 composed of two furnaces, one side calcined quicklime, the other side discharges the exhaust gas without firing the quicklime.

여기서 스크러버(13)의 스택(20)에 설치된 더스트측정센서(44)는 연속적으로 배가스의 더스트농도를 측정한다.Here, the dust measurement sensor 44 installed in the stack 20 of the scrubber 13 continuously measures the dust concentration of the exhaust gas.

이와 같이 측정된 더스트농도는 미리 세팅된 설정치와 비교되어 측정된 더스트농도가 설정치보다 클때는 블로워(24)를 작동시키고, 측정된 더스트농도가 설정치보다 작을때는 블로워(24)를 가동시키지 않는다.The dust concentration measured in this way is compared with a preset value and the blower 24 is operated when the measured dust concentration is larger than the set value, and the blower 24 is not operated when the measured dust concentration is smaller than the set value.

여기서 반복적으로 측정된 배가스의 더스트농도는 측정되어 축적된 더스트농도와 비교하여 현재 더스트농도와 이전의 더스트농도가 변동이 있을 경우에는 유량조절댐퍼(28)의 개도를 조절한다.Here, the dust concentration of the flue gas repeatedly measured is compared with the measured and accumulated dust concentration to adjust the opening degree of the flow control damper 28 when the current dust concentration and the previous dust concentration change.

도 5는 본 발명에 따른 샤프트킬른 배가스의 이차 제진장치를 설치한 벤튜리 스크러버의 집진효율을 나타내는 그래프이다.5 is a graph showing the dust collection efficiency of the venturi scrubber in which the secondary dust removing device of the shaft kiln exhaust gas according to the present invention is installed.

여기서 도시된 바와 같이 배가스의 유량을 증대시키면 더스트농도가 떨어지므로, 측정된 배가스의 더스트농도가 커지면 유량조절댐퍼(28)의 개도를 크게하여 유량을 증대시키고, 측정된 배가스의 더스트농도가 작아지면 유량조절댐퍼(28)의 개도를 줄여 유량을 감소시킨다.As shown in the drawing, when the flow rate of the exhaust gas increases, the dust concentration decreases. As the dust concentration of the measured exhaust gas increases, the flow rate is increased by increasing the opening degree of the flow control damper 28, and when the dust concentration of the measured exhaust gas decreases. The opening degree of the flow control damper 28 is reduced to reduce the flow rate.

다음으로 샤프트킬른(10)의 교체시간을 판단하여 배가스차단밸브(40)를 폐쇄하여 배가스의 배출을 차단하고, 솔레노이드밸브(42)를 개방하여 세정액을 투입시켜 헤더배관(30)과 스파져(32)에 세정액이 공급되도록 한다.Next, after determining the replacement time of the shaft kiln 10, the exhaust gas shut-off valve 40 is closed to block the discharge of the exhaust gas, the solenoid valve 42 is opened, the cleaning liquid is introduced, and the header pipe 30 and the sparger ( Make sure that cleaning solution is supplied to 32).

이상과 같이 더스트농도를 반복적으로 측정하여, 측정된 더스트농도에 편차가 발생하면 유량조절댐퍼(28)를 조절하여 측정되는 더스트농도의 편차를 줄이는 방향으로 제어한다.As described above, the dust concentration is repeatedly measured, and if a deviation occurs in the measured dust concentration, the flow control damper 28 is controlled to reduce the variation of the measured dust concentration.

이와 같이 본 발명에 따른 배가스의 이차 제진장치는 벤튜리 내부의 압력차를 증대시키지 않고도 집진효율을 크게 할 수 있다.As described above, the secondary vibration suppression apparatus of the exhaust gas according to the present invention can increase the dust collection efficiency without increasing the pressure difference inside the venturi.

또한 다수개의 스파져에 의해 배가스가 유입되므로 미세한 분진입자도 집진이 가능하여 배가스의 배출로 인한 환경오염을 방지할 수 있다.In addition, since the exhaust gas is introduced by a plurality of sparger, fine dust particles can be collected, thereby preventing environmental pollution due to the discharge of the exhaust gas.
