Title:
CHLORINE BYPASS EXTRACTION DEVICE, CHLORINE BYPASS FACILITY, CEMENT CLINKER PRODUCTION FACILITY, AND PRODUCTION METHOD OF CEMENT CLINKER
Document Type and Number:
Japanese Patent JP2021160966
Kind Code:
A
Abstract:
To provide an extraction device capable of reducing accumulation and adhesion of dust, and stabilizing operations of a chlorine bypass facility.SOLUTION: An extraction device 90 of a chlorine bypass has an extraction pipe 12 which is coupled to a kiln tail part 52 and/or rising duct 51 of a cement kiln and extracts a kiln exhaust gas 60 from an extraction hole 12a. The extraction pipe 12 has: a large diameter part 10 introducing a coolant gas 62 along a peripheral direction and mixes a kiln exhaust gas 60 and the coolant gas 62; a small diameter part 11 which has an inner diameter smaller than that of the large diameter part 10, is provided concentrically to the large diameter part 10 on an opposite side to the exhaustion hole 12a of the large diameter part 10, and derives an extraction gas 63 including the kiln exhaust gas 60 and the coolant gas 62; and a diameter reduction part 15 for narrowing a channel of the large diameter part 10 between the large diameter part 10 and the small diameter part 11.SELECTED DRAWING: Figure 2
