Title:
DEVICE AND METHOD FOR PROCESSING CHLORINE BYPASS EXHAUST GAS
Document Type and Number:
WIPO Patent Application WO/2012/124380
Kind Code:
A1
Abstract:
[Problem] To process chlorine bypass exhaust gas by keeping operating costs including maintenance management costs low, and by inhibiting heat loss. [Solution] A device for processing chlorine bypass exhaust gas (1), etc. comprising: a probe (3) which extracts a part (G1) of a combustion gas from a kiln exhaust gas passage from the kiln bottom of a cement kiln (2) to a lowermost cyclone and which cools the extracted combustion gas with a low temperature gas; and a filter type electrostatic precipitator (6) which collects dust (D2) contained in gas (G2) extracted with the probe. This device may also comprise a classifier (5) which separates coarse grain dust (D1) from the extraction gas extracted with the probe, and supply the extraction gas containing fine particles discharged from the classifier to a solid-gas separation device. An inlet gas temperature of the filter type electrostatic precipitator can be 150°C to 500°C.
