Self-pulverization clinker indirect cooling equipment for fly ash limestone calcined alumina

Abstract

The invention relates to self-pulverization clinker indirect cooling equipment for fly ash limestone calcined alumina. The self-pulverization clinker indirect cooling equipment for the fly ash limestone calcined alumina comprises a cooling machine body, an air inlet channel, an air blower and an air outlet channel. The cooling machine body is provided with a plurality of cooling modules, the cooling modules comprise a plurality of cooling pipes, the cooling modules are arranged in parallel in the vertical direction, the cooling pipes of all of the cooling modules are communicated with one another, the cooling module at the lowest end of the cooling machine body is connected with one end of the air inlet channel, the air blower is connected with the other end of the air inlet channel, the upper end of the cooling module at the top end of the cooling machine body is connected with one end of the air outlet channel, and the other end of the air outlet channel is communicated with the external world. The self-pulverization clinker indirect cooling equipment for the fly ash limestone calcined alumina has the advantages that efficient indirect cooling is adopted, no dust is discharged, the time of clinker in a cooling machine is long, material pulverization effects are good, the clinker moves slowly in the cooling machine, the equipment is small in abrasion and discharges no dust, cooling air can be recycled to serve as secondary air and third air, moving parts are small, faults are few, and maintenance workload is small.

Description

technical field [0001] The invention relates to a comprehensive treatment technology of fly ash, in particular to a cooling device for self-pulverizing clinker. Background technique [0002] The calcined alumina self-powdering clinker is calcined with fly ash limestone, and the crystal form changes during the cooling process to form self-powdering clinker. During the clinker cooling process, direct contact between the material and the cooling source should be avoided. At present, most of the domestic cooling equipment for clinker production by sintering method are grate coolers, and a small part of them use single-cylinder or multi-cylinder coolers. The clinker after cooling is lumpy and does not produce powdery objects. The advantage of this structure is that the secondary air provided to the rotary kiln has a small dust content and will not affect the normal operation of the rotary kiln. However, for self-powdering clinker, the use of traditional cooling equipment will ca...

AI Technical Summary

Problems solved by technology

However, for self-powdering clinker, the use of traditional cooling equipment will cause a large amount of dust to enter the kiln through the secondary air, and the clinker cannot be cooled.
