This utility model relates to the field of precooling technology and discloses a liquid nitrogen LNG two-phase precooling safety device, including two stainless steel base frames. A storage tank is mounted on the top of each of the two stainless steel base frames. A cooling mechanism is located on the left side of the storage tank for precooling the tank body. A pressure relief mechanism is located on the right side of the storage tank for depressurizing the tank body. An explosion-proof mechanism is located on the right side of the interior of the storage tank. An insulating support mechanism is located on the top of each of the two stainless steel base frames. The cooling mechanism includes a sealing cover, the right side of which is located on the left side of the storage tank. In this utility model, the sealing cover integrates the LNG low-pressure export pipeline, the precooling pipeline, and the liquid nitrogen pipeline, allowing the introduction of LNG and liquid nitrogen to achieve simultaneous precooling of liquid nitrogen and LNG. This reduces the cost and loss of single-medium precooling, avoids the risk of localized overcooling, and improves the precooling efficiency and safety of the LNG storage tank.
