Title:
EXHAUST GAS TREATING DEVICE AND EXHAUST GAS TREATING METHOD
Document Type and Number:
Japanese Patent JP2019051485
Kind Code:
A
Abstract:
To provide an exhaust gas treating device capable of stably suppressing Hg discharge amount to a low level while suppressing a running cost.SOLUTION: A clinker manufacturing device 1 includes a pulverizer 12 which pulverizes cement raw material M1, a cement kiln 10 which calcines cement raw material M4 pulverized by a pulverizer 12, thereby, manufactures cement clinker M5 and, at the same time, supplies burning gas G1 generated on an inner part by calcination to the pulverizer 12, a dust collector 16 which collects granular bodies contained in pulverizer discharge gas G2 discharged from the pulverizer 12, a raw material measuring instrument 14 which measures the quantity of cement raw material M1 to be introduced to the pulverizer 12, a feeder 26 which treats dust collector discharge gas G3b by means of adsorbent Ad for adsorbing Hg contained in the dust collector discharge gas G3 discharged from the dust collector 16 and a controller 28 which controls a contact quantity to the adsorbent Ad of the dust collector discharge gas G3b based on a measurement result of the raw material measuring instrument 14.SELECTED DRAWING: Figure 3
