Description

Technical Field

[0001] The utility model relates to the technical field of urea lightering, in particular to a ship-based urea lightering control system device. Background Art

[0002] With the increase in global trade, maritime transport continues to expand. As the vehicle for ocean transport, ship engine emissions pose new challenges to human life, causing pollution and harm to the environment. Selective catalytic reduction (SCR), a key technology for ship engine exhaust aftertreatment, selectively reduces NOx in ship exhaust to N2 and H2O.

[0003] As an important component of the reducing agent in the selective catalytic reduction (SCR) technology, urea solution is continuously transported from the urea daily tank to the injection pipe and fully reacts in the reaction chamber. The existing urea daily tank has a daily cycle, and the transfer system needs to cyclically fill the urea daily tank. This increases the risk of damage. When the transfer pump is damaged, it needs to be repaired, and the work is stopped. Utility Model Content
