Title:
排ガス中の硫黄酸化物量を低減させるシステム及び方法
Document Type and Number:
Japanese Patent JP7015794
Kind Code:
B2
Abstract:
The present application relates to a spray tower (1) arranged to be vertically positioned and having an inner space (100), wherein the spray tower comprises, a central exhaust gas pipe (7) arranged for introducing exhaust gas into the inner space of the spray tower through an exhaust gas inlet (2) positioned at a proximal end (7b) of the central exhaust gas pipe, the central exhaust gas pipe being positioned at a bottom end (1a) of the spray tower in installed position, the central exhaust gas pipe being in fluid connection with the inner space of the spray tower through an exhaust gas inlet at a top end (7b) of the central exhaust gas pipe, and at least one exhaust gas outlet (3) arranged for withdrawing purified exhaust gas from the inner space of the spray tower, the exhaust gas outlet being positioned at a top end (1b) of the spray tower in installed position, the exhaust gas outlet being in fluid connection with the inner space of the spray tower, wherein from the exhaust gas inlet to the exhaust gas outlet, a general exhaust gas flow is passing through the inner space of the spray tower, one or more spray devices (41, 42) configured to provide a stream of scrubber liquid within the inner space of the spray tower counter current to the general exhaust gas flow, and at least two engine exhaust gas pipes (6) being in fluid connection with the distal end of the central exhaust gas pipe. Furthermore, a method for reducing the amount of SOx in exhaust gas is described.
