Embodiment Construction

[0013] Figures 1 to 4 show examples of different kiln installations for the manufacture of cement clinker. All kiln units shown are of the ILC type, but the invention may also be used with units of the SLC type, or other combinations of such units.

[0014] All plants consist of a cyclone preheater 1 with 4 cyclones 1a, 1b, 1c and 1d. Among them, 1a is the first cyclone dust collector, 1b is the second cyclone dust collector, 1c is the third or penultimate cyclone dust collector, and 1d is the fourth or last cyclone dust collector. The cyclone dust collectors are connected in series and fed with gas / raw material coarse powder suspension through gas conduits 2a, 2b, 2c and 2d.

[0015] The apparatus also includes a calciner 3 comprising at least one inlet 9 for feeding preheated raw material meal from the last cyclone 1a through the material outlet 6; and with a separate cyclone 4 , The rotary kiln 5 is connected to a slag block cooler 7 . The gas duct 2d connecting the sepa...

Abstract

A device for the manufacture of cement comprises preheater, baking furnace, and gas catheter. The preheater comprises at least one last cyclone dust collector and at least one penultimate cyclone dust collector, which the penultimate cyclone dust collectors connect to the last cyclone dust collectors by another gas catheters to supply gas into the last cyclone dust collectors. The baking furnace comprises at least one inlet for preheating raw material coarse powder from the penultimate cyclone dust collector, which connects to the single cyclone dust collector. The gas catheter connects the single cyclone dust collector and the last cyclone dust collector, comprises at least one inlet for supplying preheating raw material coarse powder from the penultimate cyclone dust collector, to the inlet of gas catheters connecting in vertical planes between the single cyclone dust collector and the last cyclone dust collector, and is under at least one inlet for supplying preheating raw material coarse powder from the last cyclone dust collector to the baking furnace.

Description

technical field [0001] The present invention relates to a plant for the manufacture of cement clinker, comprising a preheater, a calciner and gas ducts; the preheater comprises at least one last cyclone and at least one penultimate cyclone; the The cyclone dust collector is connected in series with the last cyclone dust collector through a gas duct, and the gas from the last cyclone dust collector is fed into it; the roaster includes at least one feeding preheated raw material coarse powder from the last cyclone dust collector and connected to the separate cyclone at the rear; the gas duct connects the separate cyclone to the last cyclone and includes at least one for feeding preheated gas from the penultimate cyclone The entrance of the raw meal. Background technique [0002] Devices of the above-mentioned kind for producing cement clinker are described in DE 19649922 and DE 19524649. In these known installations, the raw material meal is fed from the milling plant into t...
