Abstract

The invention discloses a marine SCR safety control system. The marine SCR safety control system comprises a safety controller, an atmosphere bypass valve, a SCR front bypass valve, a SCR rear bypassvalve, a differential pressure sensor, a scoot blowing valve, a high-pressure air source and an air filter. The safety controller is used for controlling the atmosphere bypass valve to be switched onwhen a SCR failure reaches a set serious level, and controlling the SCR front bypass valve and the SCR rear bypass valve to be switched off after the atmosphere bypass valve is switched on; the scootblowing valve is used for executing scoot blowing operation according to a control command of the safety controller when the safety controller judges that the internal differential pressure of a SCR catalytic converter is larger than a set value. The marine SCR safety control system can automatically monitor a marine SCR system, and reduces manual detection; according to actual conditions, scoot blowing is conducted automatically; a touch display screen is adopted for convenient visual display of information and manual control over related functions; an independent direct-current power sourceis adopted for guaranteeing that the safety controller can continue to work when the marine SCR system becomes ineffective.

Description

technical field [0001] The invention relates to the field of SCR safety control, in particular to a marine SCR safety control system. Background technique [0002] According to the amendment to MAPOL Appendix VI adopted by the International Maritime Organization (IMO) in October 2008, the amendment requires that the emission requirements of marine diesel engines built on or after January 1, 2016 must meet the Tier III standard. Adding exhaust gas treatment devices is the most effective control method. However, due to the large size and high exhaust of marine engines, in the event of problems with the catalyst or components of the SCR system, the normal operation of the marine SCR system cannot be guaranteed, which needs to be resolved urgently. Contents of the invention [0003] The purpose of the present invention is to solve the problems mentioned in the background technology section above through a marine SCR safety control system. [0004] For reaching this purpose, ...
