Abstract

A novel combined cement clinker calcination and power generation system with waste heat and technique are provided. The lower part of a kiln head cover (3) is linked with an air girder grid plate device (19) which is linked with a single barrel cooling machine (2) and is arranged with a plurality of high pressure fans (20) nearby; the upper part of the kiln head cover (3) is linked with a tertiary air duct (17); one end of the middle part is linked with a burner (4) and the other end is linked with a rotary kiln (1); the upper side is linked with a D-D type calciner (10) arranged with a burner (18) nearby; a primary preheater (12) is arranged through a discharge nozzle on the bottom and is linked with a secondary preheater (11) via a connection pipeline; an elevator (16) is arranged near the pipeline; the primary preheater is linked with a novel waste heat boiler (13) via a heat steam pipeline; a high temperature fan (15) and a high-voltage electric dust collector (8) are linked between the primary preheater and a conditioning tower (14) via the pipeline; a boiler induced draft fan (9) is linked with the chimney. The system has high material dispersion, good preheating effect, high clinker output and low heat consumption.

Description

technical field [0001] The invention belongs to the technical field of cement clinker calcination and waste heat power generation, and in particular relates to a new combined cement clinker calcination and waste heat power generation system and process method. Background technique [0002] The hollow dry process with waste heat power generation rotary kiln has been applied in the cement calcination industry. A common hollow dry process kiln system with waste heat power generation is shown in Figure 1. The process method of this system is: the burner (4) sprays coal powder into In the rotary kiln (1), a high-temperature heat source is provided for firing cement clinker; the cement raw meal is fired into cement clinker after preheating, calcium carbonate decomposition, solid phase reaction and sintering reaction in the rotary kiln (1), into the kiln hood (3), and then fall into the single cylinder cooler (2) for cooling, the cooled cement clinker is sent to the clinker storage...
