Description

Technical Field

[0002] SCR stands for Selective Catalytic Reduction, which is a technology that reduces nitrogen oxide emissions in engine exhaust. For ship main engines, depending on whether the SCR system is located before or after the supercharger, it can be divided into HP-SCR and LP-SCR. HP-SCR is mainly composed of a mixer, a reactor, an exhaust valve, a urea pump unit, a ventilation unit, a sealing unit, a soot blowing unit, a heating unit, a control system, and connected pipes.

[0003] In the field of shipbuilding, in order to ensure the reliability and operational safety of HP-SCR equipment and its connecting pipes in complex environments, fixed brackets are often used to reduce pipeline vibration and noise transmission. However, the currently widely used fixed brackets are generally fixed on the outside of the 90-degree elbow, which usually leads to a large area of ​​surrounding equipment space occupation. The space outside the exhaust pipe is usually crowded, with many distributed equipment and structures. It will not only have a great impact on the layout planning of other professional equipment inside the ship, but will also cause interference conflicts between different equipment, causing the overall layout to need to be readjusted.
