The present invention relates to a liquid hydrogen storage tank and, more specifically, to a side-injection-type liquid hydrogen storage tank. The side-injection-type liquid hydrogen storage tank, which is a liquid hydrogen storage tank having a side surface (215), and a liquid hydrogen storage space (226) and a vacuum insulation space (222) that are partitioned by an inner face (224) of the tank, comprises: an injection head (290) including a head injection tube (280) extending from the side surface (215) to the vacuum insulation space (222), and a head discharge passage (285); a liquid hydrogen injection tube (240) having one end connected to the head injection tube (280) and the other end connected to a lower portion (212) of the storage space (226); a vaporized hydrogen discharge tube (230) having one end connected to an upper portion (210) of the storage space (226) and the other end connected to the head discharge passage (285); and an opening/closing means for opening and closing the head injection tube (280) and the head discharge passage (285). In accordance with the present invention, it is possible to inject liquid hydrogen from the side surface of the liquid hydrogen storage tank while preventing any backflow of liquid hydrogen.

    본 발명은 액체수소 저장탱크에 관한 것으로, 보다 상세하게는 측면주입형 액체수소 저장탱크에 관한 것이다. 이를 위해, 측면(215)을 가지며, 탱크내면(224)에 의해 액체수소의 저장공간(226)과 진공단열공간(222)이 구획되는 액체수소 저장탱크에 있어서, 측면(215)에서 진공단열공간(222)까지 연장되는 헤드주입관(280) 및 헤드배출통로(285)를 갖는 주입헤드(290); 일단이 헤드주입관(280)에 연결되고, 타단이 저장공간(226)의 하부(212)에 연결되는 액화수소 주입관(240); 일단이 저장공간(226)의 상부(210)에 연결되고, 타단이 헤드배출통로(285)에 연결되는 기화수소 배출관(230); 및 헤드주입관(280)과 헤드배출통로(285)을 개폐하는 개폐수단;을 포함하는 것을 특징으로 하는 측면주입형 액체수소 저장탱크가 제공된다.
