When the vessel is freezing in the desert (also called the sieve net) where the air in the closed tank is discharged when the ship is navigating in the low temperature region, that is, between -0 ° C. and -50 ° C., the air in the tank is not properly discharged, Water or the like can not be injected or discharged. Furthermore, the buoys may freeze inside the buoy chamber and freeze the buoys. If the vessel slips to one side or collides with the ship at this time, water will enter the tank. In the worst case, the ship will sink Can occur. These problems have to be solved in the case of vessels passing through the cryogenic region of the sub-region in the Arctic region in order to reduce the oil costs and to shorten the operation time by rapidly recording the glaciers in the Arctic region due to global warming .

However, the prior art includes a plurality of auxiliary thermally conductive pins contacting a first thermally conductive pipe disposed along the inside of the first electric hot wire, and is provided on the outer surface of the net desiccant to contact with the net desiccant film. It is possible to reduce the opening ratio of the opening of the mesh desiccant when the fluid is discharged from the inside of the tank through the air vent head due to the hot wire apparatus directly attached to the mesh desiccant, . Therefore, there is a problem that a pressure loss is required to increase the fluid discharge pressure for smooth fluid discharge. In order to solve such a pressure loss problem, the overall size of the airbottom head including the mesh desiccant and the like must be increased, but it is practically impossible to increase the airbotthed head in a limited space in a narrow vessel. 1, the upper and lower portions of the lid 81 are open to allow the snow, rain, ice, or cold seawater to flow directly into the net desert support plate or the first heat conduction pipe And the heat efficiency may be deteriorated. In addition, since the structure of the hot-wire apparatus provided in the mesh desiccant is complicated and separated from the cover, it is inconvenient to separate the cover and the hot-wire apparatus in order to repair the hot- There is a problem that it is not easy.
