Description

Изобретение относитс  к промышленности строительства и стройматериалов, в частности к устройствам дл  предварительной термической обработки в потоке газов зернистой шихты, направл емой затем в пла-« ви ьную печь дл  выработки технологического продукта.The invention relates to the construction and building materials industry, in particular, to devices for preliminary heat treatment in a stream of gases of a granular charge, then sent to a production furnace for producing a process product.

Известен аппарат дл  термической обработки зернистых материалов в кип щем слое с противоположным движением теплоносител  и материала, содержащий конические реторты с попеременно кип щими и падающими сло ми, разделенными газовыми промежутками, образуемыми путем пульсирующей подачи воздуха. В этом аппарате дл  равномерной обработки материала часть теплоносител  отвод т из газового промежутка каждой реторты в следующую по ходу движеии; воздуха 1).A known apparatus for the thermal treatment of granular materials in a fluidized bed with opposite motion of a heat-transfer fluid and a material contains conical retorts with alternately boiling and falling layers separated by gas gaps formed by pulsating air supply. In this apparatus for uniform processing of the material part of the coolant is diverted from the gas gap of each retort to the next along the movement; air 1).

Интенсификаци  процесса тепловой обработки зернистого материала достигаетс  при увеличении температуры греющей среды. Однако в установках кип щего сло  повышение температуры ограничено возможкостью перегрева отдельных частиц.Intensification of the process of heat treatment of the granular material is achieved by increasing the temperature of the heating medium. However, in fluidized bed installations, the temperature increase is limited by the possibility of overheating of individual particles.

В кип щем слое отдельные частицы могут находитьс  неопределенное врем , преIn a fluidized bed, individual particles can be found indefinitely, before

вышающее врем , необходимое дл  их обработки . В результате возможен перегрев частиц, слипание их и образование значи .тельных по размерам конгломератов, привод щих к образованию наростов ка станках установки и невозможности проведени  процесса.output time required to process them. As a result, particles can overheat, stick together and form conglomerates of large size, which lead to the formation of growths in the machine tools of the installation and the impossibility of carrying out the process.

Кроме того, при соударении отдельных частиц во врем  их возврат но-поступательного движени  происходит истирание и измельчение последних. В результате этого имеет место повыщенный пылеунос и необходима сложна  и дорога  система улавливани  уноса и возврата его в процесс,In addition, when individual particles collide during their return to motion, abrasion and grinding of the latter occur. As a result of this, increased dust trapping takes place and a complicated and expensive system for trapping ablation and returning it to the process is necessary,
