Title:
EXHAUST GAS MERCURY REMOVAL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/003845
Kind Code:
A1
Abstract:
This exhaust gas mercury removal system (1) comprises: a mercury concentration meter (11) for measuring the concentration of mercury contained in exhaust gas discharged from a dust-collecting device (7) that removes dust from a mercury-containing exhaust gas E, and outputting an output value corresponding to the measurement results; an active carbon-supplying device (12) for supplying active carbon to exhaust gas upstream of the dust-collecting device (7); and a control device (13) for controlling the active carbon-supplying device (12) on the basis of the output value such that when the output value is less than a first threshold value, the active carbon-supplying device (12) supplies a specified amount of active carbon intermittently, whereas when the output value equals or exceeds the first threshold value, the active carbon-supplying device (12) continuously supplies active carbon in a supply amount corresponding to the rate of change in the output value.
