Solid component separator control device, solid component separating device, marine exhaust gas scrubber system, and marine diesel engine

Abstract

In order to facilitate discharge of a solid component from a solid component separator with an appropriate timing, a centrifugal separator control device (133) (solid component separating device) forcontrolling a discharge timing at which a solid component discharged from an engine (diesel engine (101)) is separated from scrubber water, after having been absorbed into the scrubber water, by meansof a centrifugal separator (122) (solid component separator), and the separated solid component is discharged from the centrifugal separator (122) is provided with a discharge timing control unit which, on the basis of a value corresponding to the output of the diesel engine (101), determines the discharge timing of the solid component from the centrifugal separator (122).

Description

technical field [0001] The present invention relates to a marine exhaust gas washing system, a solid component separation device such as a centrifugal separator for purifying circulating water in the scrubbing system, a control device for a solid component separator constituting the solid component separation device, and a marine diesel engine. Here, the marine exhaust gas scrubbing system is equipped with a scrubber for removing SOx, NOx, unburned carbon, and the like contained in the exhaust gas of the marine diesel engine. Background technique [0002] In marine diesel engines and the like, an exhaust gas scrubbing system can be used to remove particulate matter (solid content) such as unburned carbon contained in exhaust gas. In this exhaust gas scrubbing system, after absorbing the solid content in the washing water, which is water for dedusting, the solid content is separated from the washing water by a solid content separator. In the solid component separator, the se...

AI Technical Summary

Problems solved by technology

If the above-mentioned discharge is performed without sufficient accumulation of solid components, the amount of washing water discharged together with the solid components will increase, resulting in a decrease in concentration.

On the other hand, if the solid content accumulates too much, it will solidify and become difficult to discharge
