Abstract
Description
Technology Field
[0001] The present invention relates to a lithium hydroxide cartridge unit for a submarine, and more specifically, to a lithium hydroxide (LiOH) cartridge unit for a submarine that optimizes the size of the equipment and the number of cartridges, and improves airflow through structural improvements such as air inlet / outlet and cartridge placement. Background Technology
[0002] Submarines must operate underwater for extended periods. Advanced electronic technology, firepower equipment, and hull size determine a submarine's performance. To achieve this capability, enhanced survivability during prolonged underwater operations is required; however, due to the enclosed nature of the space, fresh air cannot be supplied from the outside. Consequently, the increase in carbon dioxide concentration from crew respiration necessitates surfacing to ventilate the vessel. Yet, surfacing during operations or wartime is fatal and poses a life-threatening risk to the entire crew. Therefore, significant research and development are being conducted to maintain fresh air within submarines.
[0003] For example, a device using a LiOH cartridge is introduced as a known technology. A LiOH cartridge unit according to the conventional technology consisted of a main body, a door, an air inlet and an air outlet, and a knob for fixing the cartridge.
[0004] However, conventional cartridge units had the disadvantage of being unsuitable for vessels requiring a smaller capacity because the number of LiOH cartridges was standardized. Additionally, the loading direction of the LiOH cartridges was longitudinal, and two cartridges were installed side by side in a row, resulting in a complex airflow path and a problem where a gap occurred where air bypassed at the point where the two cartridges met. Furthermore, conventional cartridge units were not equipped with a configuration to tightly seal the LiOH cartridges against the internal opening of the unit body, and since both the duct inlet and outlet were located at the top of the unit body, there was a problem of significant air pressure loss inside the unit body.

[0018] According to the present invention, a lithium hydroxide (LiOH) cartridge unit for removing carbon dioxide inside a submarine can be provided. It has the advantage of optimizing the size of the equipment and the number of cartridges, and improving airflow through structural improvements such as air inlet / outlet and cartridge placement. Accordingly, air pressure loss can be minimized, and carbon dioxide can be efficiently removed even with a small amount of airflow and air pressure. Furthermore, by applying a cartridge stopper to improve the rate of carbon dioxide removal from the air to increase the passage rate of incoming air through the cartridge unit, it has the advantageous effects of achieving miniaturization and improving efficiency.
[0019] Specifically, cartridge units can be applied in the required quantity to match the capacity requirements of the vessel currently in operation, and the required airflow can be reduced as the number of cartridges decreases. Furthermore, by applying cartridges in a transverse direction rather than a longitudinal one and positioning the duct inlets / outlets at the top and bottom of the unit, the internal airflow of the main body is optimized, thereby minimizing pressure loss. Additionally, the installation of stoppers to secure the cartridges minimizes vibration during vessel movement and increases the airtightness between the main body opening and the cartridges, thereby improving the air passage rate through the cartridges. This results in improved carbon dioxide removal capabilities. Moreover, the application of a wing bolt fastening method to the door section enhances sealing power and minimizes air leakage. Additionally, supports are installed for the ducts connected to the unit, reinforcing the duct support structure.

[0053] Furthermore, cartridge units can be applied in the required quantity to match the capacity of the currently operating vessel, and the required airflow can be reduced as the number of cartridges is reduced. Additionally, by applying cartridges in the transverse direction rather than the longitudinal direction and positioning the duct inlet / outlet at the top and bottom of the unit, the internal airflow of the main body can be optimized to minimize pressure loss.
[0054] Furthermore, by installing a stopper to secure the cartridge, vibration during box movement is minimized and the airtightness between the main body opening and the cartridge is increased, thereby improving the air passage through the cartridge and enhancing the carbon dioxide removal capability.
[0055] In addition, applying a wing bolt fastening method to the door section improves sealing performance and minimizes air leakage. Furthermore, the installation of supports for the ducts connected to the unit offers the advantage of reinforcing the duct support structure.
