Description

증류용 고압스팀중의 응축액 배액장치Condensate drainage device in high pressure steam for distillation

본 고안은 증류용 고압스팀중의 응축액 배액장치에 관한 것으로, 특히 증류탑에서 유연탄 건류시 발생되는 코크스오븐가스(Coke Oven Gas)중의 불순물질인 암모니아, 황화수소, 벤젠, 톨루엔, 크실렌을 포집하여 증류시키는 고압 스팀에 유입된 다량의 응축수를 제거하는 증류용 고압스팀중의 응축액 배액장치에 관한 것이다.The present invention relates to a condensate drainage device in a high pressure steam for distillation, and particularly, to collect and distill the impurities such as ammonia, hydrogen sulfide, benzene, toluene, and xylene, which are impurities in coke oven gas generated by coking coal drying in a distillation column. The present invention relates to a condensate drainage device in a high pressure steam for distillation that removes a large amount of condensate introduced into high pressure steam.

일반적으로, 제1도에 도시한 바와같이 증류용 고압스팀에 다량 유입된 응축수를 배액 처리하기 위해 스팀이송배관의 중간중간에 설치되는 응축수배액트랩(Trap)(10)은 스팀유입관(3)을 통해 응축수를 포함하는 고압스팀이 흡입되고, 스팁이 다수의 배출구(5)를 통해 방출되며, 응축수가 유입구 상부에서 상승되면 플로트(Float)(2)가 받침대(6)를 따라 상향이동되며, 이때 플로트에 의해 닫혀 있던 응축수배출관(4)이 개방되면서 응축수가 응축수배출관으로 방출된다.In general, as shown in FIG. 1, the condensate drain trap 10, which is installed in the middle of the steam transfer pipe for draining the condensed water introduced into the high pressure steam for distillation, is a steam inlet pipe 3. The high pressure steam including the condensate is sucked through, the steam is discharged through a plurality of outlets 5, the float (2) is moved up along the pedestal 6 when the condensate is raised from the top of the inlet, At this time, the condensate discharge pipe 4, which was closed by the float, is opened and the condensate is discharged to the condensate discharge pipe.

그러나, 상기 응축수배액트랩(10)은 응축수처리속도가 늦고, 소량의 응축수를 배액할 수 있기 때문에 스팀이송배관을 흐르는 스팀중 응축수를 완전히 분리해 낼수 없고, 이로써 다량의 응축수가 혼합된 고압스팀이 증류탑 내로 유입되어 스팀의 압력과 열량은 물론 증류탑내의 압력과 온도도 급락시켜 증류탑의 증류효율이 떨어지고, 이로인해 설비 운전에 불안전한 요소를 제공하게 된다.However, since the condensate drain trap 10 has a low condensate treatment rate and can drain a small amount of condensate, the condensate can not completely separate the condensate from the steam flowing through the steam transport pipe, and thus, a high-pressure steam mixed with a large amount of condensate is provided. The distillation column's distillation efficiency is lowered by inflowing into the distillation column and the pressure and temperature of the steam as well as the pressure and temperature in the distillation column.

본 고안은 상기와 같은 종래의 문제점을 해결하여 스팀이송배관을 흐르는 증류용 고압스팀으로부터 다량의 응축수를 짧은 시간내에 완벽하게 배액이 가능하도록 하기 위한 증류용 고압스팀중의 응축액 배액장치를 제공함에 그 목적이 있다.The present invention provides a condensate drainage device in a high pressure steam for distillation to completely drain a large amount of condensed water from the high pressure steam for distillation flowing through the steam transfer pipe in a short time. There is a purpose.

도면을 참조하여 본 고안을 상세히 설명한다.The present invention will be described in detail with reference to the drawings.

제2도는 본 고안에 따른 증류용 고압스팀중의 응축액 배액장치를 나타내는 단면도이고, 제3도는 본 고안에 따른 증류용 고압스팀중의 응축액 배액장치를 나타내는 요부단면도이다.2 is a cross-sectional view showing a condensate drainage device in the distillation high pressure steam according to the present invention, Figure 3 is a main cross-sectional view showing a condensate drainage device in the high pressure steam for distillation according to the present invention.

본 고안에서는 증류용 고압스팀중에 유입된 응축수를 저장 처리할 수 있는 원통형의 응축액배액탱크(11)가 강재으로 제작되고, 이 응축액배액탱크의 상부에 스팀이송배관과 연결되는 응축수유입관(12)이 설치되어 있다.In the present invention, a cylindrical condensate drain tank 11 capable of storing and treating condensate introduced into a high pressure steam for distillation is made of steel, and a condensate inlet pipe 12 connected to a steam transport pipe at the top of the condensate drain tank. Is installed.

이때, 응축수배액탱크(11)에는 그 중앙부에 원통형의 플로트(Float)가이드관(13)이 지지대(14)에 의해 고정되도록 내장되어 있다.At this time, in the condensate drain tank 11, a cylindrical float guide tube 13 is embedded in the central portion thereof to be fixed by the support 14.

또한, 플로트가이드관(13)에는 그 하부에 한쌍의 응축수유입관(21)이 설치되어 있고, 그 하단부가 깔때기형상으로 형성되는 응축수유입관(21)은 응축수배액탱크(11)내에 차오르는 응축액을 플로트가이드관(13)내로 유입시키게 된다.In addition, the float guide tube 13 is provided with a pair of condensate inlet pipe 21 at the lower portion thereof, and the condensate inlet pipe 21 whose lower end portion is formed in a funnel shape has a condensate filling up in the condensate drain tank 11. It is made to flow into the float guide pipe (13).

이때, 응축수유입관(21) 사이에 위치하도록 플로트가이드관(13)의 하부 중앙에 연결되는 응출수배액관(20)은 밸브(22)에 의해 개폐되면서 응축수유입관(21)을 통해 플로트가이드관내로 유입되는 응축수를 응축수배액탱크(11)의 외부로 배출하게 된다.At this time, the condensed water drainage pipe 20 connected to the lower center of the float guide pipe 13 so as to be located between the condensed water inlet pipes 21 is opened and closed by the valve 22 and in the float guide pipe through the condensed water inlet pipe 21. Condensate is introduced into the discharged to the outside of the condensate drain tank (11).

여기서, 내부에 수소가스가 충전되어 있는 플로트(Float)(16)는 플로트가이드관(13)의 내주면을 따라 응축수의 부력에 의해 상하강되도록 내장되어 있고, 플로트가이드관(13)의 중단부에 내장된 스토퍼판(15)에 의해 그 상승정도가 제한된다.Here, the float 16 filled with hydrogen gas is built up and down by buoyancy of the condensate along the inner circumferential surface of the float guide tube 13, and is suspended in the suspended portion of the float guide tube 13. The degree of elevation is limited by the built-in stopper plate 15.

특히, 플로트(16)의 하부에 부착되어 응축수배액관(20)의 상단부에 끼워지는 응축수밸브관(19)은 그 외주면에 다수의 응축수배액구(19-1)가 형성되어 있는데, 이 응축수배액구(19-1)는 하부쪽으로 갈수록 점차 큰 직경을 이루도록 형성되어 있다.In particular, the condensate valve tube 19 attached to the lower portion of the float 16 is fitted to the upper end of the condensate drain pipe 20 has a plurality of condensate drain holes (19-1) is formed on the outer peripheral surface, this condensate drain hole 19-1 is formed to have a larger diameter gradually toward the lower side.

그리고, 플로트(16)와 접하는 플로트가이드관(13)의 하면에는 팩킹(Packing)(18)이 설치되어 플로트와 플로트보호관의 하면 사이로 응축수가 누설되는 현상을 방지하게 된다.In addition, a packing 18 is provided on a lower surface of the float guide tube 13 in contact with the float 16 to prevent the condensate from leaking between the float and the lower surface of the float protective tube.

또한, 플로트가이드관(13)에 설치되는 응축액배출구(17)는 플로트(16)의 상부에 차있는 소량의 응축수를 플로트가이드관의 외부로 배출하는 동시에 플로트가이드관의 내압을 응축수배액탱크(11)의 내압인 5∼7㎏/㎠으로 유지시키는 역할을 하게된다.In addition, the condensate discharge port 17 installed in the float guide pipe 13 discharges a small amount of condensate filled in the upper portion of the float 16 to the outside of the float guide pipe, and simultaneously controls the internal pressure of the float guide pipe 11 in the condensate drain tank 11. ) To maintain the internal pressure of 5 ~ 7㎏ / ㎠.

이하, 본 고안의 작용을 설명한다.Hereinafter, the operation of the present invention.

고압의 스팀이 흐르는 스팀이송배관과 연결되는 응축수유입관(12)을 통하여 응축수배액탱크(11)에 유입된 응축액은 탱크의 하부에 누적되면서 그 수위가 상승되면 응축수유입관(21)을 통해 서서히 차올라오게 된다.The condensate introduced into the condensate drainage tank 11 through the condensate inlet pipe 12 connected to the steam transfer pipe through which the high pressure steam flows is accumulated in the lower part of the tank and gradually increases through the condensate inlet pipe 21. It comes up.

이때, 응축수유입관(21)을 통해 플로트가이드관(13)내에 유입되는 응축수는 플로트(16)를 밀어올리게 되고, 이에 따라 응축수밸브관(19)이 플로트와 함께 상승된다.At this time, the condensed water introduced into the float guide tube 13 through the condensed water inlet pipe 21 pushes up the float 16, and thus the condensed water valve pipe 19 is raised together with the float.

여기서, 응축수는 응축수밸브관(19)의 응축수배액구(19-1)를 통하여 응축술배액관(20)으로 방출되는데 그 방출량의 조절은 응축수가 소량인 경우 플로트가 조금 상승하게 되어 응축수배액구(19-1)의 작은 구멍으로 응축수 방출이 이루어지고, 응축수가 다량인 경우 플로트의 상승폭이 커져서 응축수배액구의 보다 큰 구멍으로 응축수 방출이 이루어진다.Here, the condensate is discharged to the condensation drainage tube 20 through the condensate drainage port 19-1 of the condensate valve pipe 19, the control of the discharge amount is a small amount of condensate to increase the float is condensate drainage ( The condensate is discharged into the small hole of 19-1), and in the case of a large amount of condensate, the float rises and the condensate is discharged into the larger hole of the condensate drain.

한편, 본 고안은 응축수배액탱크(11)와 플로트가이드관(13)에는 그 내부가 증류용 고압스팀으로 5∼7㎏/㎠의 압력이 걸려있고, 외부와 연결되는 응축수배액관(20)에는 그 내부에 대기압이 걸려있다.On the other hand, the present invention is the condensate drainage tank 11 and the float guide pipe 13, the inside of the high pressure steam for distillation, the pressure of 5 ~ 7kg / ㎠, the condensate drainage pipe 20 connected to the Atmospheric pressure is applied inside.

따라서, 플로트(16)는 플로트가이드관(13)의 내압에 의해 패킹(18)에 밀착되어 있다가 응축수의 부력에 의해 상승하게 된다.Therefore, the float 16 is in close contact with the packing 18 by the internal pressure of the float guide pipe 13, and then rises due to the buoyancy of the condensate.

본 고안은 고압스팀의 응축액을 그 양에 관계없이 신속히 외부로 배출시킴으로써 고압스팀의 압력 및 열량의 감소를 방지하고, 이로부터 증류공정의 이상현상에 의한 증류공정의 불안정 및 설비사고를 미연에 방지할 수 있는 효과를 제공하게 된다.The present invention prevents the reduction of pressure and calorie of high pressure steam by quickly discharging the condensate of high pressure steam to the outside regardless of the amount, thereby preventing instability and equipment accident of the distillation process due to abnormal phenomenon of the distillation process. Will provide the effect.
