Abstract

The invention discloses a cement clinker cooling system and method. The cooling system comprises a rotary kiln, a hot kiln hood, an annular cooling machine, a bag-type dust collector, a zipper machine, a crusher and a bucket chain conveyor. The annular cooling machine is divided into three cooling sections. Cement clinker is cooled through the three cooling sections, and hot air generated in each cooling section is utilized. The cement clinker cooling system and method can overcome the defects in the prior art of being large in device investment, floor area and civil engineering investment, more in accessory devices, troublesome in device maintaining and overhauling and the like.

Description

technical field [0001] The invention belongs to the technical field of cement production, and in particular relates to a cement clinker cooling system and a cooling method. Background technique [0002] At the beginning of the birth of the rotary kiln in the cement industry, there was no clinker cooling equipment, and the hot clinker was dumped in the open storage yard for natural cooling. At the end of the 19th century, a single-tube cooler appeared, followed by a multi-tube cooler. In 1930, the German Boli Hughes company successfully developed the rotary grate cooler on the basis of the invention of the Liber kiln. In 1937, Fuller Company of the United States began to produce the first push grate cooler. For more than 100 years, in the tide of scientific and technological progress in the international cement industry, some of them have been eliminated after continuous improvement, replacement and long-term development. At present, the new dry process cement production l...
