본 고안은 소각로의 가스쿨러로 고온의 연소가스 배출시 가스쿨러의 변형을 방지하기 위한 소각로의 가스쿨러 변형 방지장치에 관한 것이다.The present invention relates to a gas cooler deformation preventing device of an incinerator for preventing the deformation of the gas cooler when the discharge of high-temperature combustion gas to the gas cooler of the incinerator.

일반적으로 소각로는 첨부도면 제1도에서와 같이 고분자화합물, 가연성폐기물 목재 등을 연소시키는 소각로(1), 상기 소각로에서 연소된 고온의 연소가스가 닥트(2)를 통해 이송되어 옴에 따라 연소가스의 온도를 냉각시키는 가스쿨러(Gas Cooler)(3), 냉각된 연소가스가 닥트(4)를 통해 이송되어 옴에 따라 연소가스내 함유된 유해가스를 제거하는 스크러버(Scrubber)(5), 유해가스가 제거된 다음 또 다른 닥트(6)를 통해 이송되어 옴에 따라 연소가스내에 함유된 분진을 제거한 다음 깨끗한 연기만을 대기중으로 배출시키는 멀티 싸이크(Multi Cyclone), 백휠터, 전기집 진기 등의 집진기(7)로 이루어진다.Incinerators generally burn incinerators (1) for burning high-molecular compounds, combustible waste wood, etc. as shown in FIG. Gas cooler (3) to cool the temperature, scrubber (5) to remove the harmful gas contained in the combustion gas as the cooled combustion gas is transferred through the duct (4), Dust collectors such as Multi Cyclone, Back Filter, Electrostatic precipitator, etc., which remove the dust contained in the combustion gas as it is removed and then transferred through another duct (6), and then discharge only clean smoke into the atmosphere. )

따라서, 소각로(1)에서 연소가 이루어지면 연소시 발생된 고온의 연소가스는 닥트(2)를 통해 이송되어 가스쿨러(3)에서 냉각된 다음 또 닥트(4)를 통해 스크러버(4)로 유입되므로 연소가스내에 함유된 유해가스가 제거된다.Therefore, when combustion occurs in the incinerator 1, the hot combustion gas generated during combustion is transferred through the duct 2, cooled in the gas cooler 3, and then introduced into the scrubber 4 through the duct 4. Therefore, the harmful gas contained in the combustion gas is removed.

그후 유해가스가 제거된 연소가스는 집진기(7)에서 분진이 제거된 다음 대기중으로 방출된다.The combustion gas after which noxious gas has been removed is discharged to the atmosphere after dust is removed from the dust collector 7.

상기한 바와 같은 소각로에서 연소가스를 냉각시키는 가스쿨러(3)에는 빠른 열교환을 위해 다수개의 연소가스냉각판(8)이 설치된다.The gas cooler 3 cooling the combustion gas in the incinerator as described above is provided with a plurality of combustion gas cooling plates 8 for rapid heat exchange.

종래에는 제2도 및 제3도(a)에 도시한 바와 같은 연소가스냉각판(8)의 끝단을 상, 하고정판(9a)(9b)에 용접고정하여 닥트(2)를 통해 고온의 연소가스 유입실(10)내로 유입됨에 따라 유입된 연소가스는 연소가스냉각관(8)을 통해 이동하면서 외부의 차거운 공기와 열교환을 하여 냉각된 다음 토출실(11)을 스커러버(5)축으로 이송된다.Conventionally, the end of the combustion gas cooling plate 8 as shown in FIGS. 2 and 3 is welded and fixed to the upper and fixed plates 9a and 9b to burn the high temperature through the duct 2. The combustion gas introduced as it flows into the gas inlet chamber 10 moves through the combustion gas cooling tube 8 to be cooled by heat exchange with external cool air, and then the discharge chamber 11 is moved to the scrubber 5 shaft. Transferred.

그러나 이러한 종래의 장치는 연소가스냉각관(8)이 상고정판(9a)에 직접 용접하여 고정시키는 경우 유입실(10)내로 유입되는 고온의 연소가스에 의해 열팽창될 때 팽창되는 양(약 17-20mm 정도)을 흡수하지 못하여 용접부위에 열응력이 발생하게 되므로 용접부위가 파손될 염려가 있다.However, such a conventional apparatus has an amount of expansion when the combustion gas cooling tube 8 is thermally expanded by the high temperature combustion gas flowing into the inflow chamber 10 when the combustion gas cooling tube 8 is directly welded and fixed to the upper fixing plate 9a. 20mm) can not be absorbed because the thermal stress is generated in the welded site may damage the welded site.

이를 방지하기 위해, 고온의 연소가스의 유입에 따라 연소가스냉각판(8)이 길이 방향(수직방향)으로 가변되도록 된 기술이 제안된 바 있다.In order to prevent this, a technique has been proposed in which the combustion gas cooling plate 8 is varied in the longitudinal direction (vertical direction) in accordance with the inflow of high temperature combustion gas.

즉, 제3도의 (b)에 도시한 바와 같이 연소가스냉각관(8)이 하부는 하고정판(9b)에 용접고정하고 연소가스냉각관(8)의 상부는 상고정판(9a)에 유동 가능하게 결합한다음 연소가스냉각관의 외측으로 실링재(13)를 별도의 플랜지(14)으로 지지하여 연소가스냉각관(8)과 상고정판(9a)의 기밀을 유지하도록 되어 있다.That is, as shown in (b) of FIG. 3, the combustion gas cooling tube 8 is welded and fixed to the fixed plate 9b, and the upper portion of the combustion gas cooling tube 8 can flow to the upper fixing plate 9a. The sealing material 13 is supported by a separate flange 14 on the outside of the combustion gas cooling tube to maintain the airtightness of the combustion gas cooling tube 8 and the upper fixing plate 9a.

따라서 유입실(10)내로 고온의 연소가스가 유입됨에 따라 연소가스냉각관(8)이 이 팽창되면 제3도 (b)의 일점쇄선과 같이 연소가스냉각관(8)이 상고정판(9a)과 기밀을 유지하면서 상측으로 길이가 가변되므로 연소가스냉각관(8)의 연결부가 파손되지 않게 된다.Therefore, when the combustion gas cooling tube 8 expands as the high temperature combustion gas flows into the inflow chamber 10, the combustion gas cooling tube 8 is the upper fixing plate 9a as shown by the dashed-dotted line in FIG. Since the length is changed upward while maintaining the airtightness and airtightness, the connection portion of the combustion gas cooling tube 8 is not broken.

그러나 이러한 장치 또한, 연소가스냉각관(8)이 연결부가 파손되지 않는 이점을 갖는 반면, 각 연소가스냉각관(8)에 별도의 실링재(13)와 플랜지(14)이 각각 필요하게 되므로 작업성이 떨어지게 됨을 물론 누기를 방지하기 위해 상고정판(9a)가 연소가스냉각판(8)의 접속부를 정밀 가공하여야 되었으므로 생산시 많은 비용이 필요하게 되고, 일정간격으로 연소가스 누출을 방지하기 위하여 고정 플랜지 부분을 다시 조이거나 실링재를 교환하는 정비가 정기적으로 필요하게 된다.However, such a device also has the advantage that the combustion gas cooling pipe 8 has the advantage that the connection is not broken, whereas each combustion gas cooling pipe 8 requires a separate sealing material 13 and the flange 14, respectively, so that the workability The upper fixing plate 9a has to be precisely processed at the connection part of the combustion gas cooling plate 8 to prevent leakage, and thus, a large amount of cost is required in production, and a fixed flange to prevent combustion gas leakage at regular intervals. Maintenance to retighten or to replace the sealant will be necessary on a regular basis.

본 고안은 종래의 이와 같은 문제점을 해결하기 위해 안출한 것으로서, 별도의 부품을 사용하지 않고도 고온의 연소가스에 의해 연소가스냉각관이 팽창되더라도 연결부가 파손되지 않게하여 가스쿨러의 수명을 연장시키는데 그 목적이 있다.The present invention has been made to solve such a problem in the prior art, even if the combustion gas cooling tube is expanded by a high temperature combustion gas without using a separate component, so that the connection is not broken to extend the life of the gas cooler There is a purpose.

상기 목적을 달성하기 위한 본 고안의 형태에 따르면, 함체의 상고정판에 연소가스냉각관을 용접고정하는 가스쿨러에 있어서, 상고정판의 하방으로 위치되는 함체의 연소가스냉각관이 열변형함에 따라 이를 보상하는 신축부를 형성하여서된 소각로용 가스쿨러의 변형 방지 장치가 제공된다.According to a form of the present invention for achieving the above object, in the gas cooler for welding and fixing the combustion gas cooling pipe to the upper fixing plate of the housing, as the combustion gas cooling tube of the housing located below the upper fixing plate heat deformation An apparatus for preventing deformation of a gas cooler for an incinerator formed by forming a compensating expansion and contraction unit is provided.

이하, 본 고안을 일실시예를 도시한 첨부된 도면 제4도를 참고로하여 더욱 상세히 설명하면 다음과 같다.Hereinafter, with reference to Figure 4 of the accompanying drawings showing an embodiment of the present invention in more detail as follows.

첨부도면 제4도는 본 고안 장치가 적용된 가스쿨러의 종단면도로서,4 is a longitudinal cross-sectional view of a gas cooler to which the device of the present invention is applied.

본 고안은 상고정판(9a)의 하방으로 위치되는 함체(12)에 신축부(15)를 형성하는데, 이때 신축부의 형상을 본 고안의 일실시예에서와 같이 자바라 형태로 할 수도 있지만 그 형태를 연소가스의 고온에 의해 연소가스냉각관(8)이 팽창될 때 이를 보상할 수 있는 형태로 다양하게 변경 가능하게 된다.The present invention forms the stretchable portion 15 in the housing 12 positioned below the upper fixing plate 9a, wherein the stretchable portion may have a bellows shape as in one embodiment of the present invention. When the combustion gas cooling tube 8 is expanded by the high temperature of the combustion gas, it can be variously changed in a form that can compensate for this.

이와 같이 구성된 본 고안은 소각로(1)에서 소각대상물을 소각시킴에 따라 발생된 연소가스가 닥트(2)를 통해 유입실(10)내로 유입되어 연소가스냉각관(8)내를 이동되면서 냉각됨에 따라 고온의 연소가스에 의해 연소가스냉각관(8)이 팽창된다.The present invention configured as described above is the combustion gas generated in the incinerator (1) by burning the incineration object is introduced into the inlet chamber (10) through the duct (2) is cooled while moving in the combustion gas cooling pipe (8) Accordingly, the combustion gas cooling tube 8 is expanded by the high temperature combustion gas.

이에 따라 연소가스냉각관(8)의 상단이 상고정판(9a)에 고정되어 있고 상고정판(9a)의 하방으로 위치되는 함체(12)에 신축부(15)가 형성되어 있으므로 연소가스 냉각관(8)의 팽창량만큼 신축부(15)가 팽창된다.Accordingly, since the upper end of the combustion gas cooling tube 8 is fixed to the upper fixing plate 9a and the expansion and contraction unit 15 is formed in the housing 12 positioned below the upper fixing plate 9a, the combustion gas cooling tube ( The expansion and contraction part 15 is expanded by the amount of expansion of 8).

이와 같이 신축부(15)가 팽창되면 함체(12)의 상부인 유입실(10)전체가 상승된다.When the expansion and contraction unit 15 is expanded in this way, the entire inflow chamber 10, which is the upper portion of the enclosure 12, is raised.

상기 함체(12)의 상부가 팽창되면 상기 함체의 연결된 닥트(2)가 팽창되는 양을 보상하게 되므로 닥트(2)와 가스쿨러(3)의 연결부가 파손되지 않게 된다.When the upper portion of the enclosure 12 is expanded, the amount of expansion of the connected duct 2 of the enclosure is compensated for, so that the connection portion between the duct 2 and the gas cooler 3 is not damaged.

한편, 소각작업을 완료하고 나면 팽창되었던 연소가스냉각관(8)이 수축되므로 수축되는 양을 신축부(15)가 흡수하게 되므로 연소가스냉각관(8)과 상고정판(9a)의 고정부분이 파손되는 것을 방지하게 되는 것이다.On the other hand, after the incineration is completed, the expansion and contraction of the combustion gas cooling tube 8 is expanded, so that the expansion and contraction portion 15 absorbs the amount of contraction, so that the fixed portion of the combustion gas cooling tube 8 and the upper fixing plate 9a It will prevent damage.

이상에서와 같이 본 고안장치는 연소가스냉각관(8)의 팽창을 신축부(15)가 보상하게 되므로 가스쿨러의 제작이 용이하게 되어 제작비가 저렴함은 물론 연소가스냉각관(8)의 연결부가 파손되지 않게 되므로 장기간 사용 가능하게 되는 효과를 얻게 된다.As described above, the inventive device compensates for the expansion of the combustion gas cooling tube 8 by the expansion and contraction unit 15, so that the production of the gas cooler is easy and the manufacturing cost is low, as well as the connection portion of the combustion gas cooling tube 8. Since it is not broken, the effect of being available for a long time is obtained.
