이하 본 발명의 바람직한 실시예에 따른 쿨링 타워 팬의 얼음 제거장치를 첨부된 도면을 참조하여 상세히 설명한다. 그러나 본 발명은 이하에서 개시되는 실시예에 한정되는 것이 아니라 서로 다른 다양한 형태로 구현될 것이며, 단지 본 실시예는 본 발명의 개시가 완전하도록 하며, 통상의 지식을 가진자에게 발명의 범주를 완전하게 알려주기 위해 제공되는 것이다.Hereinafter, an ice removing device of a cooling tower fan according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but will be implemented in various forms, and only the present embodiments are intended to complete the disclosure of the present invention and to those skilled in the art to fully understand the scope of the invention. It is provided to inform you.

도 1은 본 발명의 일실시예에 따른 쿨링 타워 팬의 얼음 제거장치를 도시한 도면이다.1 is a view showing the ice removing device of the cooling tower fan according to an embodiment of the present invention.

도 1에 도시된 바와 같이, 본 발명에 따른 쿨링 타워 팬의 얼음 제거장치(100)는, 냉각수(14)를 분사하는 냉각수 스프레이 장치(10)와, 냉각수 스프레이 장치(10)를 제어하는 제어부(20)를 구비한다. 참조번호 21은 펌프이고, 23은 열교환기를 말한다.As shown in FIG. 1, the ice removing apparatus 100 of the cooling tower fan according to the present invention includes a coolant spray device 10 for spraying the coolant 14 and a control unit for controlling the coolant spray device 10 ( 20). Reference numeral 21 is a pump and 23 is a heat exchanger.

도 2는 도 1의 냉각수 스프레이 장치의 냉각수 분사를 도시한 도면이다.FIG. 2 is a diagram illustrating cooling water spray of the cooling water spray device of FIG. 1.

도 2에 도시된 바와 같이, 냉각수 스프레이 장치(10)는 쿨링 타워의 팬 블레이드(11) 방향으로 연장된 냉각수 공급라인(13)과, 냉각수 공급라인(13)을 선택적으로 개폐하는 냉각수 컨트롤 밸브(15)와, 냉각수 공급라인(13)에 다수개 장착되는 분사노즐(17)을 구비한다.As shown in FIG. 2, the cooling water spray device 10 includes a cooling water supply line 13 extending in a direction of a fan blade 11 of a cooling tower, and a cooling water control valve for selectively opening and closing the cooling water supply line 13. 15) and a plurality of injection nozzles (17) mounted on the cooling water supply line (13).

냉각수 공급라인(13)은 쿨링 타워(19)의 팬 블레이드(11)의 방향으로 연장되 게 구비된다. 이러한 냉각수 공급라인(13)은 쿨링 타워(19)로 회수되는 냉각수 라인(12)에 연결된다. 냉각수 라인(12)에는 고온의 냉각수가 흘러 쿨링 타워(19)로 유입된다. 따라서, 냉각수 라인(12)의 고온의 냉각수는 냉각수 공급라인(13)을 통해 분사노즐(17)로 분사됨이 가능하다. 분사노즐(17)은 냉각수 공급라인(13)에 일정 간격의 다수개로 장착되어, 팬 블레이드(11)에 냉각수(14)를 분사한다. 이러한 냉각수(14)의 분사는 제어부(20)의 제어를 통해 선택적으로 분사된다.Cooling water supply line 13 is provided to extend in the direction of the fan blade 11 of the cooling tower (19). This cooling water supply line 13 is connected to the cooling water line 12 which is returned to the cooling tower 19. The high temperature coolant flows into the coolant line 12 and flows into the cooling tower 19. Therefore, the high temperature cooling water of the cooling water line 12 may be injected into the injection nozzle 17 through the cooling water supply line 13. The injection nozzles 17 are mounted at a plurality of predetermined intervals in the cooling water supply line 13 to inject the cooling water 14 to the fan blades 11. The injection of the coolant 14 is selectively injected through the control of the controller 20.

제어부(20)는 팬 블레이드(11)를 구동하는 구동모터(16)의 신호를 전송받아, 구동모터(16)의 구동 부하량을 인식한다. 즉, 대기 온도가 영하로 내려가면 팬 블레이드(11)에 얼음이 지속적으로 쌓이게 되고, 얼음의 자중에 의해 구동모터(16)의 부하량의 변동이 발생된다. 따라서, 제어부(20)는 구동모터(16)의 부하량이 일정 기준값 이상임으로 판단하면, 팬 블레이드(11)의 표면에 과다한 얼음의 생성으로 판단한다. 이어서, 제어부(20)는 냉각수 컨트롤 밸브(15)를 개방하여 냉각수(14)가 분사노즐(17)을 통해 분사되도록 한다. 그러면, 팬 블레이드(11)의 표면에 생성된 얼음은 고온의 냉각수(14)에 의해 제거된다.The control unit 20 receives a signal from the driving motor 16 driving the fan blade 11 and recognizes the driving load of the driving motor 16. That is, when the air temperature drops below zero, ice is continuously accumulated on the fan blades 11, and the load of the driving motor 16 is generated by the weight of the ice. Therefore, when the controller 20 determines that the load of the driving motor 16 is equal to or greater than a predetermined reference value, the controller 20 determines that excessive ice is generated on the surface of the fan blade 11. Subsequently, the controller 20 opens the coolant control valve 15 to allow the coolant 14 to be injected through the spray nozzle 17. Then, the ice generated on the surface of the fan blade 11 is removed by the hot water 14.

상기 구성에 따른 본 발명의 쿨링 타워 팬의 얼음 제거장치의 작동을 설명한다.It describes the operation of the ice removing device of the cooling tower fan of the present invention according to the above configuration.

먼저, 제어부(20)는 팬 블레이드(11)를 구동하는 구동모터(16)의 부하량의 증감 여부를 측정한다. First, the controller 20 measures whether the load amount of the drive motor 16 driving the fan blade 11 is increased or decreased.

이어서, 제어부(20)는 구동모터(16)의 부하량의 측정값이 기설정된 측정값을 초과함으로 판단하면, 냉각수 콘트롤 밸브(15)를 개방한다. 이러한 냉각수 콘트롤 밸브(15)의 개방에 따라 쿨링 타워로 회수되는 냉각수의 일부가 냉각수 공급라인(13)으로 흐른다. Subsequently, when the controller 20 determines that the measured value of the load amount of the drive motor 16 exceeds the preset measured value, the controller 20 opens the coolant control valve 15. As the cooling water control valve 15 is opened, a part of the cooling water recovered to the cooling tower flows to the cooling water supply line 13.

다음, 도 3에 도시된 바와 같이, 냉각수 공급라인(13)으로 공급된 냉각수는 분사노즐(17)을 통해 분사되어 팬 블레이드(11)의 표면에 축적된 얼음(18)을 녹여 제거한다.Next, as shown in FIG. 3, the cooling water supplied to the cooling water supply line 13 is injected through the injection nozzle 17 to melt and remove the ice 18 accumulated on the surface of the fan blade 11.

이상, 본 발명을 도면에 도시된 실시예를 참조하여 설명하였다. 그러나, 본 발명은 이에 한정되지 않고 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명과 균등한 범위에 속하는 다양한 변형예 또는 다른 실시예가 가능하다. 따라서, 본 발명의 진정한 보호범위는 이어지는 특허청구범위에 의해 정해져야 할 것이다.The present invention has been described above with reference to the embodiments shown in the drawings. However, the present invention is not limited thereto, and various modifications or other embodiments falling within the scope equivalent to the present invention are possible by those skilled in the art. Therefore, the true scope of protection of the present invention should be defined by the following claims.

상기와 같은 본 발명에 따른 쿨링 타워 팬의 얼음 제거장치는 다음과 같은 효과를 갖는다.The ice removing device of the cooling tower fan according to the present invention as described above has the following effects.

대기 온도가 영하로 내려갈 경우 팬 블레이드 표면에 축적된 얼음을 자동 제거할 수 있도록 함으로써, 팬을 구동하는 구동모터의 부하를 줄여 고장 발생을 방지한다.By allowing the ice to accumulate on the fan blade surface when the air temperature drops below zero, the load on the drive motor that drives the fan is reduced to prevent failure.
