본 발명의 다른 목적은 수냉식 투입 슈트를 통과하여 온도 상승된 냉각수(온수화 됨)는 회수하여 소정 사용처에 공급할 수 있도록 한 수냉식 폐기물 투입 슈트를 제공하는 것에 있다.It is another object of the present invention to provide a water-cooled waste input chute which is capable of recovering and supplying the cooling water (warmed in temperature) which has risen through the water-cooled input chute to a predetermined place of use.

이와 같은 목적을 달성하기 위한 본 발명은 상부에 폐기물이 투입되는 호퍼와, 상기 호퍼의 하부에 위치하는 투입슈트와, 상기 투입슈트의 하부에 위치하여 투입 적재되는 폐기물을 연소실로 밀어내는 급진장치를 포함하는 폐기물의 소각설비에 있어서, 상기 투입슈트는 금속재질로 내측벽과 외측벽이 이중으로 밀폐된 중공형의 사각형상이며, 상기 외측벽의 일측 하부에는 냉각수 주입구가 형성되고 타측의 상부에는 냉각수 배출구가 형성된 것을 특징으로 한다. The present invention for achieving the above object is a hopper for the waste is injected into the top, an injection chute located in the lower portion of the hopper, a radical device for pushing the waste placed in the loading chute into the combustion chamber to the combustion chamber In the waste incineration plant comprising, the input chute is a hollow rectangular shape in which the inner wall and the outer wall is double sealed with a metal material, the cooling water inlet is formed on one side lower portion of the outer wall and the cooling water outlet on the other side Characterized in that formed.

또한 본 발명은 상기 투입슈트의 내측벽과 외측벽 사이에는 벽체를 고정하기 위한 다수개의 벽체 고정핀이 설치된 것을 특징으로 한다.In addition, the present invention is characterized in that a plurality of wall fixing pins for fixing the wall between the inner wall and the outer wall of the input chute.

따라서 이와 같은 본 발명은 폐기물 소각시설에서 사용되는 폐기물 투입용 슈트를 이중 수냉식 슈트를 이용한 수냉 방식으로 냉각시켜 슈트 내부(내부벽)의 소손이나 폐기물 등이 고착되는 문제점을 배제하며, 상기 폐기물의 연속적인 안정공급으로 소각운전을 수행할 수 있는 효과를 가진다.Therefore, the present invention is to cool the waste chute used in the waste incineration facility in a water cooling method using a double water-cooled chute to eliminate the problem of burning or waste of the inside of the chute (inner wall) is fixed, the continuous It has the effect of performing incineration operation with stable supply.

이하, 본 발명의 바람직한 실시 예들은 첨부된 도면을 참조하여 설명한다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

도 1은 본 발명에 따른 수냉식 폐기물 투입 슈트가 설치된 소각설비의 구성도이다.1 is a block diagram of an incineration plant equipped with a water-cooled waste input chute according to the present invention.

도시된 바와 같이, 본 발명에 따른 수냉식 폐기물 투입슈트(20)가 적용되는 소각설비의 구성은, As shown, the configuration of the incineration plant to which the water-cooled waste input chute 20 according to the present invention is applied,

크게 상부에 폐기물이 투입되는 호퍼(10)와, 상기 호퍼(10)의 하부에 위치하는 사각형상의 투입슈트(20)와, 상기 투입슈트(20)의 하부에 위치하여 투입 적재되는 폐기물을 연소실(40)로 밀어내는 급진장치(30)를 포함한다.The hopper 10 into which the waste is largely injected, the rectangular chute 20 located below the hopper 10, and the waste placed and loaded below the chute 20 are placed in a combustion chamber ( And a radical device 30 for pushing it to 40.

이를 보다 상세하게 알아보면,In more detail,

상기 투입슈트(20)는 금속재질로 도 2에서와 같이 내측벽(21)과 외측벽(22)이 이중으로 밀폐된 중공형의 사각형상이며, 상기 내측벽(21)과 외측벽(22) 사이에는 벽체를 고정하기 위한 다수개의 벽체 고정핀(23)이 설치된다.The injection chute 20 is a metal material and has a hollow rectangular shape in which the inner wall 21 and the outer wall 22 are double sealed as shown in FIG. 2, and between the inner wall 21 and the outer wall 22. A plurality of wall fixing pins 23 are installed to fix the wall.

또한 상기 외측벽(22)의 일측 하부에는 냉각수 주입구(24)가 형성되고, 타측의 상부에는 냉각수 배출구(25)가 형성된다.In addition, a coolant inlet 24 is formed at one lower side of the outer wall 22, and a coolant outlet 25 is formed at an upper side of the other side.

따라서 미 도시된 냉각수 공급수단을 통해 상기 냉각수 주입구(24)로 주입된 냉각수는 투입호퍼(20)의 내측벽(21)과 외측벽(22) 사이의 공간을 통과하여 상부에 형성된 냉각수 배출구(25)를 통해 외부로 배출되게 된다.Therefore, the coolant injected into the coolant inlet 24 through the coolant supply unit (not shown) passes through the space between the inner wall 21 and the outer wall 22 of the input hopper 20 to form the coolant outlet 25 formed thereon. It is discharged to the outside through.

또한, 상기 투입호퍼(20)의 내측은 연소실(40)에서 유입되는 열기 등으로 인해 고온인 상태를 유지함으로, 상기 냉각수 주입구(24)로 주입된 냉각수는 투입호퍼(20)의 내측벽(21)과 외측벽(22) 사이의 공간을 통과하면서 열 교환 현상에 따라 온도 상승하여 냉각수 배출구(25)를 통해 배출되는 물은 온수가 된다.In addition, the inside of the input hopper 20 is maintained at a high temperature due to the heat introduced from the combustion chamber 40, the cooling water injected into the cooling water inlet 24 is the inner wall 21 of the input hopper 20 ) And the water discharged through the cooling water outlet 25 becomes hot water while passing through the space between the outer wall 22 and the heat exchange phenomenon.

본 발명에서는 이러한 온수를 이용하여 필요한 사용처에 사용할 수 있도록 구성한다.In the present invention, using such hot water is configured to be used where necessary.

한편, 상기 투입호퍼(20)의 하부에 형성된 급진장치(30)는 유압 실린더(31)에 의하여 왕복 구동하는 장치로, 상기 호퍼(10) 및 투입 슈트(20)를 통해 하방으로 투입 및 적재된 폐기물을 우측으로 밀어내어 폐기물이 연소실(40)로 향하도록 하여준다.On the other hand, the feeding device 30 formed in the lower portion of the input hopper 20 is a device for reciprocating by the hydraulic cylinder 31, the input and loaded downward through the hopper 10 and the input chute 20 Push the waste to the right to direct the waste to the combustion chamber (40).

이와 같이 구성된 본 발명의 동작을 이하 설명한다.The operation of the present invention configured as described above will be described below.

먼저, 소각시설의 폐기물 투입구인 호퍼(10)로 폐기물이 투입되면, 투입된 폐기물은 투입슈트(20)를 통해 폐기물 급진장치(30)의 일측에 적재되어 진다.First, when the waste is injected into the hopper 10 which is a waste inlet of the incineration facility, the injected waste is loaded on one side of the waste feeding device 30 through the input chute (20).

동시에 미 도시된 냉각수 공급수단을 통해 투입 슈트(20)의 냉각수 주입구(24)로 냉각수가 주입되고, 상기 냉각수 주입구(24)로 주입된 냉각수는 투입호퍼(20)의 내측벽(21)과 외측벽(22) 사이의 공간을 통과하여 상부에 형성된 냉각수 배출구(25)를 통해 외부로 배출 된다.At the same time, the coolant is injected into the coolant inlet 24 of the inlet chute 20 through a coolant supply means, and the coolant injected into the coolant inlet 24 is the inner wall 21 and the outer wall of the inlet hopper 20. Pass through the space between the 22 is discharged to the outside through the cooling water outlet 25 formed in the upper portion.

따라서 투입 슈트(20)는 냉각되며, 투입슈트(20)의 내부 표면에는 냉기류가 형성 된다.Therefore, the chute 20 is cooled, and cold air flow is formed on the inner surface of the chute 20.

또한 상기 투입 슈트(20)의 하방에 적재된 폐기물을 감지한 급진장치(30)는 급진 동작을 수행하게 된다. In addition, the feeding device 30, which senses the waste loaded under the chute 20, performs a feeding operation.

즉 유압실린더(31)가 동작하여 작동로드가 이완되면서 급진장치(30)의 선단부(32)가 우측방향으로 이동하게 되고, 이때 적재된 폐기물은 연소실(40)로 밀려 나가게 된다. That is, the hydraulic cylinder 31 operates to relax the working rod, and the tip end portion 32 of the feeding device 30 moves to the right direction. At this time, the loaded waste is pushed out to the combustion chamber 40.

상기 연소실로 밀려 나간 폐기물은 소각되며, 그 열기가 역류하여 투입 슈트(20) 및 호퍼(10) 측으로 이동되면서 폐기물은 복사열에 의한 고착이 진행될 조짐이 보이게 된다.The waste pushed out into the combustion chamber is incinerated, and its heat is reversed and moved to the input chute 20 and the hopper 10, and the waste is likely to be fixed by radiant heat.

그러나 본 발명에 따른 투입 슈트(20)가 냉각된 상태를 유지하고 동시에 그 주변이 냉각된 분위기를 가지게 되어, 복사열에 의한 폐기물의 고착을 방지하게하여 준다.However, the input chute 20 according to the present invention maintains a cooled state and at the same time has a cooled atmosphere around it, thereby preventing the seizure of waste by radiant heat.

동시에 냉각된 투입 슈트(20)의 표면이 냉각되어 있어 소각로 내 압력 변동에 의한 역화시 에도 소손이나 폐기물 또는 연소물 등이 고착되지 않게 된다.At the same time, the surface of the cooled input chute 20 is cooled, so that no burning, waste, or combustion products are stuck even when the incinerator is backfired by pressure fluctuations.

따라서 역화 발생시에도 상기 투입 슈트(30)는 손상 없이 연속적으로 안정 운전을 할 수 있게 된다.Therefore, even when the backfire occurs, the closing chute 30 can be continuously operated stably without damage.

한편, 본 발명에 따르자면, 상기 투입호퍼(20)의 내측은 연소실(40)에서 유입되는 열기 등으로 인해 고온인 상태를 유지함으로, 상기 냉각수 주입구(24)로 주입된 냉각수는 투입호퍼(20)의 내측벽(21)과 외측벽(22) 사이의 공간을 통과하면서 열 교환 현상에 따라 온도가 상승하여 냉각수 배출구(25)를 통해 배출되는 물은 온수가 되므로, 이와 같이 냉각작용을 수행하고 온도 상승된 온수는 필요한 사용처에 이용할 수 있도록 유도된다. Meanwhile, according to the present invention, since the inside of the input hopper 20 maintains a high temperature state due to the heat introduced from the combustion chamber 40, the cooling water injected into the cooling water inlet 24 is the input hopper 20. As the temperature rises according to the heat exchange phenomenon while passing through the space between the inner wall 21 and the outer wall 22 of the water), the water discharged through the cooling water outlet 25 becomes hot water, thus performing the cooling operation and the temperature Elevated hot water is derived for use where needed.
