Low-temperature liquid transport ship broadside structure water spraying device

Abstract

The invention discloses a low-temperature liquid transport ship broadside structure water spraying device which comprises a flow guide plate (1), a stainless steel spraying pipe (2), an angle steel transverse support (4) and a fixed handrail (5), the flow guide plate (1) and the angle steel transverse support (4) are fixed to the fixed handrail (5), and the stainless steel spraying pipe (2) is fixed to the angle steel transverse support (4) and connected to a ship firefighting pipeline. The guide plate (1) is arranged on the inner side of the lower part of the stainless steel spray pipe (2), and the fixed rail (5) is fixed on a deck. According to the water spraying device, under the condition that spraying is continuously kept in the ship-to-shore or ship-to-ship low-temperature liquid conveying process, sprayed water flow covers the whole collecting pipe area broadside outer plate along the flow guide plate, leaked or sputtered low-temperature dropping liquid can be completely vaporized and evaporated through spraying water, and the low-temperature dropping liquid cannot make contact with the ship body structure outer plate; and low-temperature cold brittleness cannot be caused to the ship body structure.

Description

technical field [0001] The invention relates to a water spraying device for a side structure of a cryogenic liquid transport ship. Background technique [0002] Compared with general transport ships, ships that transport cryogenic liquids (liquefied ethylene, liquefied petroleum gas, and liquefied natural gas, etc.) often have special considerations in their design; cryogenic liquids are transported from ship to shore or ship to ship through loading and unloading arms. If there is a leak during loading and unloading, it will cause cracks in the deck and outer plate, or lead to the failure of the entire structure; moreover, in the process of cryogenic liquid transmission, there is another risk, that is, the low temperature will affect the The influence of the surrounding environment; although the cryogenic liquid is transmitted through the loading and unloading arm or the hose, the transmission period is generally long, the entire loading and unloading arm or the hose is alwa...

If there is a leak during loading and unloading, it will cause cracks in the deck and outer plate, or lead to the failure of the entire structure; moreover, in the process of cryogenic liquid transmission, there is another risk, that is, the low temperature will affect the The influence of the surrounding environment; although the cryogenic liquid is transmitted through the loading and unloading arm or the hose, the transmission period is generally long, the entire loading and unloading arm or the hose is always in a low temperature state, frost will form on the loading and unloading arm and the hose, and then the surrounding A low-temperature temperature field is formed, and long-term contact will have a low-temperature effect on the human body or hull structure
