본 발명을 설명하기에 앞서, 핀 튜브 방청설비(10)에 대한 주요 구성요소를 개략적으로 살펴보기로 한다.Prior to describing the present invention, the main components of the fin tube rust prevention apparatus 10 will be described in brief.

상기 핀 튜브 방청설비(10)는, 먼저 분사노즐(12)로부터 고압분사되는 방청유(14)의 비산을 막고 방청유(14)의 회수 및 핀 튜브(16)가 통과할 수 있는 구조로 이루어진 코팅박스(18)와; 이 코팅박스(18)의 상부와 연결하여 코팅박스(18) 내부에 존재하는 유해가스를 흡입.배출시키기 위한 송풍기(20)와, 상기 코팅박스(18)로부터 회수되는 방청유(14)의 경화를 방지하는 열교환기(22)와, 상기 방청유(14)의 순환 및 공급에 대한 압력을 제공하는 순환펌프(24)와, 방청유(14)를 보충.공급하는 공급탱크(26)로 구성된다.The fin tube rust prevention facility 10 is a coating box made of a structure that first prevents scattering of the rust preventive oil 14 sprayed from the injection nozzle 12 and recovers the rust preventive oil 14 and allows the fin tube 16 to pass through. 18; The blower 20 for suctioning and discharging the harmful gas existing in the coating box 18 by connecting to the upper portion of the coating box 18 and the hardening of the rust preventive oil 14 recovered from the coating box 18. It comprises a heat exchanger (22) for preventing, a circulation pump (24) for providing a pressure for circulation and supply of the rust preventive oil (14), and a supply tank (26) for replenishing and supplying the rust preventive oil (14).

구체적으로 살펴보면, 상기 코팅박스(18)는, 양 측면에 고주파 용접된 핀 튜브(16)가 수평 상태에서 통과하면서 화살표 방향으로 지나갈 수 있도록 통공(28)이 각각 형성되며, 아울러 통공(28)을 중심으로 상부커버(30)와 하부커버(32)로 나뉘다.Specifically, the coating box 18, the through-holes 28 are formed to pass in the direction of the arrow while the high-frequency welded fin tube 16 passes in a horizontal state on both sides, respectively, and also through the hole 28 The upper cover 30 and the lower cover 32 is divided into the center.

이러한, 상기 상부커버(30)의 상면에는 코팅박스(18)의 내부와 소통되는 상태로 배출라인(34)의 일측이 연결되어 있고, 그 타측은 송풍기(20)에 연결된다. 이때 상기 배출라인(34)상에는 카본재질로 이루어진 정화필터(36)가 갖추어지도록 구성되어, 방청코팅시 코팅박스(18)의 내부에 존재하는 유해가스가 상기 정화필터(36)에 의해 정화되어 외부로 배출되게 된다. Such, the upper surface of the upper cover 30 is connected to one side of the discharge line 34 in communication with the interior of the coating box 18, the other side is connected to the blower (20). At this time, on the discharge line 34 is configured to be equipped with a purification filter 36 made of a carbon material, the harmful gas present in the interior of the coating box 18 during the anti-rust coating is purified by the purification filter 36 to the outside Will be discharged.

또한, 상기 상부커버(30)의 상면에는 분사노즐(12)이 코팅박스(18)의 내부로 관통 설치되어 있어, 그 하부에 위치하는 핀 튜브(16)를 향하여 방청유(14)를 분사하게 된다. 그리고 상기 분사노즐(12)은 후술하는 순환펌프(24)의 이송라인(38)과 연결되어 방청유(14)를 계속 공급받게 된다. In addition, the upper surface of the upper cover 30, the injection nozzle 12 is installed through the interior of the coating box 18, to spray the rust-preventive oil 14 toward the fin tube 16 located in the lower portion . In addition, the injection nozzle 12 is connected to the transfer line 38 of the circulation pump 24 which will be described later to continue to receive the antirust oil (14).

상기 하부커버(32)에는 회수라인(40)을 통해 열교환기(22)와 연결되어 하부커버(32)에 모여진 방청유(14)가 열교환기(22)로 이송된다. 이때 상기 회수라인(40)에는 회수되는 방청액(14)의 찌꺼기를 걸러주기 위한 여과필터(42)가 갖추어져 있다.The lower cover 32 is connected to the heat exchanger 22 through the recovery line 40 and the rust preventive oil 14 collected in the lower cover 32 is transferred to the heat exchanger 22. At this time, the recovery line 40 is provided with a filtration filter 42 for filtering the debris of the anti-corrosive liquid 14 to be recovered.

그리고, 상기 열교환기(22)를 통과하는 방청유(14)는 연결라인(41)을 통해 순환펌프(24)와 연결되는데, 이때 연결라인(41)에는 방청유(14)를 수용한 공급탱크(26)의 공급라인(42)과 연결되며, 순환펌프(24)는 앞서 언급된 분사노즐(12)과 이송라인(38)을 통하여 서로 연결 되도록 구성된다.In addition, the rust preventive oil 14 passing through the heat exchanger 22 is connected to the circulation pump 24 through the connection line 41, in which the supply tank 26 containing the rust preventive oil 14 in the connection line 41. Is connected to the supply line 42, the circulation pump 24 is configured to be connected to each other through the aforementioned injection nozzle 12 and the transfer line 38.

따라서, 본 발명에 대한 폐열회수보일러의 핀 튜브 방청설비(10)의 동작을 살펴보면, 먼저 핀(44)이 튜브(46)에 고주파 용접되면서 이송되는 동안 제작이 완료된 핀 튜브(16) 부분은 냉각수(48)를 분사하는 냉각수단(50)을 거쳐 코팅박스(18)를 통과하는 상태로 이송된다.Therefore, looking at the operation of the fin tube rust prevention facility 10 of the waste heat recovery boiler according to the present invention, first, the fin tube 16 is completed while the fin 44 is transported while the high frequency welding to the tube 46, the portion of the cooling water It is transferred to the state passing through the coating box 18 through the cooling means 50 for spraying (48).

위와 같이 상기 핀 튜브(16)가 코팅박스(18)를 통과하는 동안, 순환펌프(24)의 동작에 의해 공급탱크(26)로부터 제공되는 방청유(14)가 공급라인(42)과 이송라인(38)을 경유하여 분사노즐(12)로 공급됨으로써, 핀 튜브(16)를 향해 고압으로 분사된다.While the fin tube 16 passes through the coating box 18 as described above, the antirust oil 14 provided from the supply tank 26 by the operation of the circulation pump 24 is supplied with the supply line 42 and the transfer line ( By supplying to the injection nozzle 12 via 38, it is injected at high pressure toward the fin tube 16. As shown in FIG.

상기 분사노즐(12)로부터 분사되는 방청유(14)는 핀 튜브(16)의 표면에 대한 방청코팅을 수행하게 되는데, 이때 냉각수단(50)을 거치더라도 핀 튜브(16)는 고주파 용접으로 인해 높은 온도를 형성하고 있어 방청유(14)가 핀 튜브(16)에 도포되는 순간 온도가 급상승하게 되면서 경화 및 건조가 바로 이루어지된다. 또한 상기 방청유(14)의 방청코팅에 의해 핀 튜브(16)를 재차 식혀주는 냉각기능도 발휘하게 된다.The rust preventive oil 14 sprayed from the injection nozzle 12 is subjected to the rust preventive coating on the surface of the fin tube 16. At this time, even though the cooling means 50, the fin tube 16 is high due to high frequency welding. As the temperature is formed, the instant the temperature is rapidly increased when the rust-preventive oil 14 is applied to the fin tube 16, curing and drying are performed immediately. In addition, by the antirust coating of the rust preventive oil 14, the cooling function of cooling the fin tube 16 again is exerted.

그리고, 방청코팅시 잔류하는 방청유(14)는 상기 하부커버(32)에 모여져 회수라인(40)을 따라 열교환기(22)로 이송되는데, 이때 여과필터(42)를 통과하면서 찌꺼기가 걸러지게 되므로 재사용이 가능하게 한다.In addition, the rust-preventing oil 14 remaining during the rust-preventive coating is collected in the lower cover 32 and transferred to the heat exchanger 22 along the recovery line 40. Enable reuse

또한, 회수되는 방청유(14)를 열교환기(22)에 통과시키는 이유는, 위에서 설명하였듯이 냉각수단(50)을 이용하여 온도를 낮추더라도 여전히 높은 온도를 형성 하고 있어, 방청유(14)의 온도가 높아지면서 경화되게 된다. 이때 열교환기(22)를 통과하면서 방청유(14)의 온도를 낮추어 경화되는 것을 방지하고, 그에 따라 각 라인이 막히게 되는 현상을 방지하게 된다.In addition, the reason why the rust-prevented oil 14 recovered is passed through the heat exchanger 22 is that, as described above, even if the temperature is lowered by using the cooling means 50, the temperature is still high. As it rises, it hardens. At this time, while passing through the heat exchanger 22 to prevent the hardening by lowering the temperature of the rust preventive oil 14, thereby preventing the phenomenon that each line is clogged.

이와 같이 상기 열교환기(22)를 통과한 방청액(14)은 순환펌프(24)의 이송력을 제공받아 상기 분사노즐(12)로 공급되어 고압분사되는 방청코팅과정을 반복하게 되며, 그와 동시에 공급탱크(26)으로부터 방청액(14)을 보충.공급받아 공급노즐(12)로 공급시키게 된다.In this way, the anti-corrosive liquid 14 passing through the heat exchanger 22 is supplied to the injection nozzle 12 by receiving the transfer force of the circulation pump 24 to repeat the anti-corrosive coating process of high-pressure injection, and At the same time, the antirust solution 14 is replenished from the supply tank 26 and supplied to the supply nozzle 12.

한편, 상기 이송라인(38)과 회수라인(40) 간에 연결되는 바이패스라인(52)에서 체크밸브(54)의 설계 압력보다 과다공급에 따른 이송라인(38)의 압력이 더 높아지게 되면, 체크밸브(54)가 자동적으로 열림 상태가 되어, 방청유(14)의 일부가 바이패스라인(52)을 통해 회수라인(40)으로 이송되어 여과필터(42)로 공급되는 순환과정을 거치게 된다.On the other hand, in the bypass line 52 connected between the transfer line 38 and the recovery line 40, if the pressure of the transfer line 38 due to oversupply is higher than the design pressure of the check valve 54, the check The valve 54 is automatically opened, and a part of the rust preventive oil 14 is transferred to the recovery line 40 through the bypass line 52 and undergoes a circulation process supplied to the filtration filter 42.

예컨데, 상기 방청설비(10)를 장시간 미 사용시에는 상기 이송라인(38)과 연결되는 드레인라인(56)의 밸브(58)를 열어 외부로 배출시키게 된다. For example, when the rust prevention facility 10 is not used for a long time, the valve 58 of the drain line 56 connected to the transfer line 38 is opened to be discharged to the outside.

따라서 본 발명의 폐열회수보일러의 핀 튜브 방청설비(10)를 사용하게 되면, 고주파 용접된 핀 튜브(16)가 바로 코팅박스(18)를 통과하게 되면서 핀 튜브(16)의 높은 온도를 이용하므로, 방청코팅에 대한 경화 및 건조가 신속하게 이루어지고, 아울러 분사노즐(12)을 통해 분사되는 방식에 의해 일정한 두께를 이루며 균일하게 코팅되게 된다.Therefore, when the fin tube rust prevention facility 10 of the waste heat recovery boiler of the present invention is used, the high frequency welded fin tube 16 directly passes through the coating box 18 and thus uses the high temperature of the fin tube 16. , The curing and drying for the rust-preventive coating is made quickly, and by the method sprayed through the injection nozzle 12 to achieve a uniform thickness and uniform coating.

이상과 같이, 본 발명은 비록 한정된 실시 예와 도면에 의해 설명되었으나, 본 발명은 이것에 의해 한정되지 않으며 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술사상과 아래에 기재될 특허청구범위의 균등범위 내에서 다양한 수정 및 변형이 가능함은 물론이다.

Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.

위와 같이 본 발명은 핀 튜브의 제작을 진행하면서 바로 방청 코팅을 수행하는 새로운 타입의 방청설비에 의하여 핀 튜브의 냉각 기능을 발휘하면서, 핀 튜브의 높은 온도를 이용하여 방청코팅과 건조가 신속하게 이루어질 수 있도록 하는 효과가 있다.As described above, the present invention provides a cooling function of the fin tube by a new type of anti-corrosion facility that performs anti-corrosive coating immediately while the fin tube is manufactured, and makes the anti-corrosive coating and drying quickly by using a high temperature of the fin tube. It has the effect of making it possible.

또한, 분사노즐을 통한 고압 분사방식이 가능하여, 방청막이 일정한 두께를 이루며 균일하게 코팅되어 방청코팅 효과를 극대화할 수 있다.In addition, the high-pressure injection method through the injection nozzle is possible, the anti-corrosion film is uniformly formed to a certain thickness can maximize the anti-corrosion coating effect.
