Description

Из-вестны агрегаты, совмещающие выполнение нескольких технологических функций при подготовке бурых углей к брикетированию. Так, например, в агрегате системы Лурги, уголь, проход  через центральную сушильную трубу, снабженную специальным размольным вентил тором, одновременно дробитс  и сущитс  в струе гор чих продуктов факельного сжигани  газа.Known units that combine the implementation of several technological functions in the preparation of brown coal for briquetting. For example, in the Lurgi system, coal, a passage through a central drying tube, equipped with a special grinding fan, is simultaneously crushed and placed in a stream of hot gas flaring products.

Предлагаемый комплексный агрегат отличаетс  конструктивным совмещением сепарирующей щахты, снабженной щахтной мельницей и обогреваемой беспламенными газовыми горелками, с сортировочным устройствам, улавливающим крупные частицы топлива.The proposed complex unit is characterized by a constructive combination of a separating shaft, equipped with a pitch mill and heated by flameless gas burners, with sorting devices that catch large particles of fuel.

Благодар  такому совмещению топочных и технологических объемов , замене сложного размольного вентил тора шахтной мельницей и применению беспламенных горелок вместо факельных существенно повышаетс  экономичность агрегата и упрощаетс  его устройство.Thanks to such a combination of furnace and process volumes, the replacement of a complex grinding fan with a mine mill and the use of flameless burners instead of flare burners, the efficiency of the unit is greatly increased and the device is simplified.

На чертеже изображена схема 1предлагаемо1го устройства.The drawing shows a diagram of the 1 proposed device.

Устройство СОСТОИТ из бункера 1, питател  2 и вертикальной шахты 3, установленной над молотковой дробилкой 4.The device consists of a hopper 1, a feeder 2 and a vertical shaft 3 installed above the hammer mill 4.

В шахту 3 вмонтированы беспламенные тазовые горелки 5, к которым газодувкой по трубопроводу 6 подают под некоторым давлением .генераторный газ, а вентил тором по трубопроводу 7 воздух.Flameless pelvic burners 5 are mounted into the shaft 3, to which a gas blower is fed through the pipeline 6 under a certain pressure of generator gas, and the fan through the pipeline 7 is air.

Кроме того, агрегат включает в себ  еще камеру улавливани  сушонки 8, циклон 9 и грохоты 10.In addition, the unit includes another camera for collecting the drier 8, a cyclone 9 and screens 10.

Работа устройства протекает следующим образом.The operation of the device proceeds as follows.

Из бункера У сырой бурый уголь (или другое исходное твердое топливо) подают питателем 2 в вертикальную шахту 3, где за счет отсоса продуктов беспламенного сжигани  газа имеетс  направленный лоток гор чих газов.From the bunker In raw brown coal (or other source solid fuel), the feeder 2 is fed to a vertical shaft 3, where, due to the suction of the products of flameless gas combustion, there is a directional tray of hot gases.

Сырое топливо, попавшее в этот поток, подвергаетс  одновременно дво кой обработке: с одной стороны, сушке (за счет передачи тепла радиацией от раскаленных поверхностей горелок и конвекцией от гор чих газов) и, с другой стороны, сепарации по крупности. При этом мелкие частицы унос тс  потоком, крупные же падают вниз в молотковую дробилку 4.Crude fuel that enters this stream is simultaneously subjected to a double treatment: on the one hand, drying (due to heat transfer by radiation from the hot surfaces of the burners and convection from hot gases) and, on the other hand, separation by size. At the same time, small particles are carried away by the stream, while large ones fall down into the hammer mill 4.
