Efficient composite vertical cement calcined clinker cooler and cooling method

Abstract

The invention relates to an efficient composite vertical cement calcined clinker cooler and a cooling method, and belongs to cement clinker coolers and cooling methods. The efficient composite vertical cement calcined clinker cooler comprises a front-end cooling device, a vertical cooling device and a crushing and air-locking device. The cooling method comprises the following steps that clinker enters the front-end cooling device from a rotary kiln at a calcination temperature of 1200-1400 DEG C; (2) the high-temperature clinker enters the vertical cooling device to be cooled continuously after being subjected to quenching; (3) the clinker which is subjected to vertical re-cooling enters a roller crusher to be extruded and crushed; and (4) the cooled and crushed clinker is discharged intoa clinker warehouse for storage through the air-locking device. The cooling method has the advantages that a traditional clinker cooling mode is integrated with a vertical cooling mode, so that the quality and the grindability of the clinker are greatly improved; the contact and heat exchange time between the clinker and the gas is longer, so that the heat exchange is more sufficient; cooling airvolume for the unit clinker is small, transmission power is not needed, power consumption is low, maintenance is easy, equipment is more reliable in operation, and the use cost is low; and the technology is simple in process, energy consumption is low, and standard emission is achieved.

Description

technical field [0001] The invention relates to a cement clinker cooler and a cooling method, in particular to a high-efficiency composite vertical cement calcined clinker cooler and a cooling method. Background technique [0002] Energy consumption in the production process of dry cement calcined clinker accounts for a large proportion of its production cost; clinker cooling is an indispensable process link in the cement clinker manufacturing process, and energy consumption and heat recovery in clinker cooling are important for high efficiency and energy saving. Calcination of dry process cement clinker is crucial. [0003] The main function of the cement clinker cooling system is to cool the cement clinker out of the kiln at a temperature of 1200~1400°C, recover waste heat, and crush it; that is, after the cement clinker is cooled, it is convenient for storage and transportation, and the waste heat of the cement clinker is recovered. Improve the quality of cement clinker ...

Problems solved by technology

[0004] At present, the dry-process cement clinker cooler is mainly driven by the grate type cooler, but there are still problems such as thin material layer, regional air supply, cross air leakage, large air distribution volume of the system, large transmission power consumption, and low cooling efficiency. There are many wearable parts and the disadvantages of high cost
