The utility model discloses a kind of hot tank exhaust liquefaction structures, including condensate backflow member being fixed on hot tank, steam exhaust pipe being installed on condensate backflow member, condensate backflow member is provided with steam-liquid blending cavity, steam exhaust pipe is provided with the steam passage of intercommunication steam-liquid blending cavity, the inlet end of steam passage is communicated with the inner cavity of hot tank by steam-liquid blending cavity, steam-liquid blending cavity inner wall and steam exhaust pipe outer wall form condensate space, steam converges to form liquid in condensate space inner wall and is backflowed to hot tank by steam-liquid blending cavity. With the effect that hot tank can be effectively pressure-relieved, reduce steam exhaust amount when hot tank pressure-relieved.

The utility model provides a steam conveying pipeline structure for coal combustion, which belongs to the field of steam conveying pipelines and comprises a first connecting pipe, a second connecting pipe, a first limit ring and a mounting sleeve, the first connecting pipe and the second connecting pipe are mounted in a butt joint manner, and a butt joint bulge is fixedly mounted at the top of the second connecting pipe. The sealing ring is installed through the butt joint protrusion and the sealing ring, so that the sealing ring and the sealing ring can be in butt joint conveniently, sealing operation is achieved, and meanwhile the first limiting ring and the second limiting ring are installed in the gap between the first connecting pipe and the second connecting pipe. Limiting can be further carried out through a first limiting ring and a second limiting ring, a threaded rod can rotate along one side of a mounting plate by rotating a plum blossom disc, a butt joint block and a mounting groove can be clamped, a threaded sleeve is used for pushing a fixing block, and the butt joint block can be clamped; and therefore, the first limiting ring and the second limiting ring can be sealed.

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.
