Description

Известный способ коксовани  углей в периодически действующих камерных печах имеет недостатки: периодичность процесса коксовани  и неуправл емость его отдельными стади ми; ограниченность сырьевой угольной базы коксовани ; относительно низка  производительность печей; неоднородность качества кокса по прочности, крупности и другим свойствам.The known method of coking coals in periodically operating chamber furnaces has drawbacks: the frequency of the process of coking and its uncontrollability by separate stages; limited raw coal coking base; furnace performance is relatively low; Coke quality heterogeneity in strength, grain size and other properties.

Описываемый непрерывный способ коксовани  углей в кольцевых печах с вращающимс  подом устран ет указанные недостатки и позвол ет получать формованный кокс и обеспечивает раздельный отвод парогазовых продуктов коксовани  по стади м.The described continuous method of coking coals in rotary hearth rotary kilns eliminates these drawbacks and allows to obtain molded coke and provides separate removal of steam and gas coking products in stages.

Особенность описываемого способа состоит в том, что процесс коксовани  ведут с нагревом свободнолежащего сло  угл  путем излучени  от подогретого свода печи.The peculiarity of the described method is that the coking process is carried out with heating of the free-lying coal layer by radiation from the pre-heated furnace roof.

До конечной температуры высокотемпературного коксовани  нагревают весь свободнолежащий слой угл , передвигаемый вращающимс  подом печи.Up to the final temperature of the high-temperature coking, the entire free-lying layer of coal, which is moved by the rotating hearth of the furnace, is heated.

Процесс коксовани  по мере передвижени  сло  угл  внутри печи осуществл ют в три основных стадии: доведени  до температуры пластического состо ни , спекани  и перехода полукокса в кокс.The coking process, as the carbon layer moves inside the furnace, is carried out in three main stages: bringing the plastic state to temperature, sintering, and the conversion of char to coke.

В кольцевой печи с вращающимс  подом в процессе коксовани  получаетс  кокс определенной формы, дл  чего предусмотрено формование пластической массы угл .In an annular rotary hearth furnace, coke is produced in a coking process of a certain shape, for which the formation of a plastic mass of coal is provided.

Парогазовые продукты в процесое коксовани  раздел ютс  на два самосто тельных потока.Steam-gas products in the coking process are divided into two independent streams.

№ 123146- 2 -No. 123146-2 -

Один поток (богатый газ с теплотой сгорани  более 7000 кал/м), отбираемый со стороны загрузки печи, содержит жидкие (конденсирующиес ) продукты коксовани  (смолу, бензольные и другие продукты). Так как объем этого газа мал (/з-/2 от общего объема получающегос  газа), то аппаратура конденсации и улавливание значительно упрощено . Возможен и более дифференцированный отбор парогазовых продуктов , позвол ющий улавливать более узкие фракции летучих продуктов .One stream (rich gas with a heat of combustion of more than 7000 cal / m) taken from the kiln feed side contains liquid (condensable) coking products (tar, benzene and other products). Since the volume of this gas is small (/ З- / 2 of the total volume of the produced gas), the condensation apparatus and trapping is considerably simplified. A more differentiated selection of vapor-gas products is also possible, allowing to capture narrower fractions of volatile products.

Другой поток (бедный газ с теплотой сгорани  2500-2300 кал/м) отбираетс  со стороны выгрузки кокса. Этот газ содержит в основном примерно 80-85% водорода, часть которого может быть использована дл  обогрева печей, а остальное количество дл  других целей, главным образом, дл  химических производств.Another stream (lean gas with a heat of combustion of 2500-2300 cal / m) is taken from the coke discharge side. This gas contains mainly about 80-85% hydrogen, part of which can be used to heat the furnaces, and the rest for other purposes, mainly for chemical production.

Предмет изобретени Subject invention

Непрерывный способ коксовани  углей в кольцевых печах с вращающимс  подом, отличающийс  тем, что, с целью получени  формованного кокса и раздельного отвода парогазовых продуктов коксовани  по стади м, процесс коксовани  ведут с нагревом свободнолежащего сло  угл  путем излучени  от подогреваемого свода печи.The continuous method of coking coals in rotary hearth-type rotary kilns, characterized in that, in order to obtain molded coke and separate removal of steam-gas coking products in stages, the coking process is heated with a free-flowing coal layer by radiation from the heated roof of the furnace.
