Description
( СПОСОБ ПРОИЗВОДСТВА ЦЕМЕНТНОГО КЛИНКЕРА(METHOD OF MANUFACTURE OF CEMENT CLINKER
Изобретение относитс к способу производства цементного клинкера из сырого цементного шлама.This invention relates to a process for the production of cement clinker from raw cement slurry.
Известен способ производства цементного клинкера Путем обжига сырь- 6 евого шлама во вращающейс , печи IjA known method for the production of cement clinker By burning the raw material - 6th sludge in a rotary kiln Ij
Недостатками способа вл ютс низка производительность и высока энергоемкость процесса.The disadvantages of the method are low productivity and high energy intensity of the process.
Наиболее близким к изобретению по to технической сущности и достигаемому результату вл етс способ производства цементного клинкера из сырого цементного шлама путем распылительной сушки шлама в потоке дымовых га- и зов и последующего обжига во вращающейс печи, причем.газы, примен емые на стадии распылительной сушки сырого цементного шлама, подвергают предварительной очистке от уносимой 20 пыли 2 .The closest to the invention to the technical essence and the achieved result is a method for the production of cement clinker from raw cement slurry by spray drying the slime in a stream of flue gases and subsequent burning in a rotary kiln, and the gases used at the stage of spray drying raw cement slurry, subjected to pre-treatment of dust carried away 20.
Недостаток известного способа заключаетс в том, что отход щие газы унос т не только пыль, но и капельки примеси сырь , в основном соединени . 25The disadvantage of this method is that the exhaust gases carry away not only dust, but also droplets of impurities of the raw material, mainly the compound. 25
хлора, серы и щелочи. После очистки пыли по мере охлаждени из отход щих газов выдел етс примесь,котора образует отложени в газоходе.chlorine, sulfur and alkali. After cleaning the dust as it cools, the impurity is released from the exhaust gases, which forms deposits in the duct.
Очистка отход щих газов от пыли приводит не только к осложнению про .цесса за счет включени в .него стадии очистки, но и к снижению производительности распылительной сушки в результате предварительного удалени гор чей пыли, что в конечном итоге сказываетс на производительности всего процесса.Purification of waste gases from dust not only leads to a complication of the process due to the inclusion in the cleaning stage, but also to a decrease in the spray drying capacity as a result of the preliminary removal of hot dust, which ultimately affects the productivity of the entire process.
Целью изобретени вл етс повышение производительности процесса и предотвращение образовани отложений в газоходе.The aim of the invention is to increase the productivity of the process and prevent the formation of deposits in the gas duct.
Поставленна цель достигаетс тем, что согласно способу производства цементного клинкера путем распылительной сушки сырьевого шлама в потоке отход щих газов с последующим обжигом во вращающейс печи, пропускание отход щих газов осуществл ют через вращающуюс печь со скороThis goal is achieved by the fact that according to the cement clinker production method by spray drying the raw sludge in a stream of flue gases followed by firing in a rotary kiln, the flue gases are passed through a rotary kiln soon
