그리고 제2유로부(34)는 다공성 메탈 엘리멘트(Metal element)를 포함하며 수소 입자 보다는 크고 수분의 입자 보다는 작은 공극을 복수로 구비한다. 따라서 수소만 제2유로부(34)를 통과하여 냉각기(6)로 이동될 수 있으며, 수분은 반응기와 반응됨을 유도한다.In addition, the second passage part 34 includes a porous metal element and has a plurality of pores that are larger than hydrogen particles and smaller than moisture particles. Therefore, only hydrogen can pass through the second flow path part 34 and move to the cooler 6, and moisture induces reaction with the reactor.

도 1 내지 도 3에 도시된 바와 같이, 반응부(40)는 유로부(30)와 하우징부(20)의 사이에 위치하며, 하우징부(20)의 내측에 있는 수분을 제거하고 수소를 발생시키는 기술사상 안에서 다양한 형상으로 이루어질 수 있다. 일 실시예에 따른 반응부(40)는 수소화합물을 포함하며, 이러한 수소화합물은 MgH2 또는 NaBH4 인 것을 특징으로 한다.As shown in FIGS. 1 to 3, the reaction part 40 is located between the flow path part 30 and the housing part 20, and removes moisture inside the housing part 20 and generates hydrogen.

Since the hydrogen sensor unit 50 is installed at a position facing the reaction unit 40, the reaction unit 40 measures the concentration of hydrogen generated by reacting with water and transmits the measured value to the control unit 70.

그리고 수분센서부(55)는 출구측에 위치한 연결관로부(22)에 설치되어 하우징부(20)에서 배출되는 수소에 포함된 수분을 측정하여 제어부(70)로 측정값을 전달한다.In addition, the moisture sensor unit 55 is installed in the connection pipe 22 located at the outlet side, measures moisture contained in hydrogen discharged from the housing unit 20 and transmits the measured value to the control unit 70.

제어부(70)는 수소센서부(50)와 수분센서부(55)의 측정값을 전달받아 수소충전소용 수분제거장치(10)의 교체여부를 알림부(80)를 통해 작업자에게 알린다.The control unit 70 receives the measured values of the hydrogen sensor unit 50 and the moisture sensor unit 55 and notifies the operator through the notification unit 80 whether to replace the moisture removal device 10 for a hydrogen charging station.

송수신부(60)는 수소센서부(50)의 측정값을 전달받아 무선신호를 발생시키며, 이러한 송수신부(60)의 무선신호는 제어부(70)로 전달된다. 제어부(70)는 송수신부(60)의 신호를 전달받으며, 알림부(80)를 통해 반응부(40)의 교체시기를 자동으로 알리므로 사용의 편의성을 향상시킬 수 있다.The transceiving unit 60 receives the measured value of the hydrogen sensor unit 50 to generate a radio signal, and the radio signal of the transceiving unit 60 is transmitted to the control unit 70.

본 발명의 일 실시예에 따른 수소충전소용 수분제거장치(10)는, 기존에 설치된 수소충전소(1)에도 용이하게 적용할 수 있으며, 별도의 저장용기 교체나 퍼지 과정없이도 수분 누적으로 인한 수소품질 문제를 해결할 수 있으며, 수소충전소(1) 가동중단시간도 최소화할 수 있다.The moisture removal device 10 for a hydrogen charging station according to an embodiment of the present invention can be easily applied to an existing hydrogen charging station 1, and hydrogen quality due to moisture accumulation without a separate storage container replacement or purging process. The problem can be solved, and the downtime of the hydrogen charging station 1 can be minimized.

만약 수소충전소용 수분제거장치(10)를 설치하지 않는 경우, 수소저장용기(5)에 누적된 수분이 프리쿨러인 냉각기(6)를 통과하면서 빙결될 수 있으며, 수소에 포함된 수분이 설정치를 초과하는 경우 수소충전소(1)의 운영이 정지될 수도 있다. If the moisture removal device 10 for a hydrogen charging station is not installed, the moisture accumulated in the hydrogen storage container 5 may freeze while passing through the cooler 6, which is a precooler, and the moisture contained in the hydrogen is If exceeded, the operation of the hydrogen charging station 1 may be stopped.

이하에서는 첨부된 도면들을 참조하여 본 발명의 일 실시예에 따른 수소충전소용 수분제거장치(10)의 작동상태를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail the operating state of the water removal device 10 for a hydrogen charging station according to an embodiment of the present invention.

수소압축기(3)에서 압축된 고압의 수소가 수소저장용기(5)에 저장된 후 수소충전소용 수분제거장치(10)에서 수분이 제거된다. 그리고 수분제거장치를 통과한 수소는 냉각기(6)를 거쳐 수소충전기(7)로 공급된다.After the high-pressure hydrogen compressed in the hydrogen compressor (3) is stored in the hydrogen storage container (5), moisture is removed from the moisture removal device (10) for a hydrogen charging station.

수소충전소용 수분제거장치(10)로 기체가 공급되면, 유로부(30)의 다공성 유로를 통과하며 냉각기(6)를 향한 방향으로 수소가 배출된다. 수소충전소용 수분제거장치(10)로 유입된 기체에 수분이 있을 경우, 반응부(40)의 수소화합물과 결합하여 수분은 제거되고 수소가 발생된다.When gas is supplied to the moisture removal device 10 for a hydrogen charging station, hydrogen is discharged in a direction toward the cooler 6 while passing through the porous flow path of the flow path part 30. When there is moisture in the gas flowing into the moisture removing device 10 for a hydrogen charging station, it is combined with the hydrogen compound of the reaction unit 40 to remove moisture and generate hydrogen.

유로부(30,31)는 단일부재로 이루어질 수 있으며, 필요에 따라 제1유로부(33)와 제2유로부(34) 등 복수의 부재로 이루어질 수도 있다.The flow path portions 30 and 31 may be formed of a single member, and may be formed of a plurality of members, such as the first flow path portion 33 and the second flow path portion 34, if necessary.

반응부(40)에 의해 수분이 제거되고 수소가 발생될 경우, 수소센서부(50)에서 측정된 수소 농도는 높아지고 수분센서부(55)에서는 수분이 측정되지 않는다. 따라서 제어부(70)는 알림부(80)를 통해 수소충전소용 수분제거장치(10)가 정삭 작동 중이라는 표시를 한다.When moisture is removed by the reaction unit 40 and hydrogen is generated, the hydrogen concentration measured by the hydrogen sensor unit 50 increases, and the moisture sensor unit 55 does not measure the moisture.
