Document Type and Number:
WIPO Patent Application WO/2013/137304
Kind Code:
A1
Abstract:
Provided is a device that is for producing cement, uniformly supplies starting materials to cyclones above a guide tube, increases heat exchange efficiency by means of uniform pre-heating, and can cause an operation having low pressure loss and low energy consumption. In the device for producing cement, between a plurality of upper-level cyclones (13A) and a lower-level cyclone (13B) disposed therebelow, a guide tube (21) is provided that causes exhaust gas led out from the lower-level cyclone (13B) to flow upward, to be distributed, and to be led to the upper-level cyclones (13A). At a position below the guide tube (21) distribution section (23) to the plurality of upper-level cyclones (13A) are disposed a number of starting material supply tubes (22), which supply cement starting materials, equal to the number of distributed exits (21a) to the upper-level cyclones (13A). The connection openings (22a) of the starting material supply tubes (22) to the guide tube (21) are disposed one at a time at positions corresponding to the flow of each revolving flow of exhaust gas flowing into the distributed exits (21a).
