Title:
EXHAUST GAS PROCESSING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/179107
Kind Code:
A1
Abstract:
[Problem] To provide a technique, when removing sulfur oxides, nitrogen oxides and soot in exhaust gas, with which equipment cost and operating cost can be reduced. [Solution] A denitrification device 2 is provided downstream of a dry desulfurization device 1. The desulfurization device 1 is provided with a reaction tower and a supply unit for supplying a desulfurization agent and particles configuring a moving layer into the reaction tower to form a falling flow thereof. For the exhaust gas, the gas velocity inside the reaction tower is set to 0.2-1.2 m/s and, by being brought into contact with the falling flow in an orthogonal flow, the sulfur oxides and soot in the exhaust gas are removed. Since no bag filter is used, no temperature-raising device is provided in the exhaust gas flow channel 11 from the outlet of the desulfurization device 1 to the inlet of the denitrification device 2.
