Изобретение относитс к области коксохимической промышленности и, в частности, к способам отверждени сырых брикетов из древесного угл .The invention relates to the field of the coke industry and, in particular, to methods for solidifying raw briquettes from charcoal.
Известные способы отверждени сырых брикетов из древесного угл заключаютс в термообработке брикетов при 190,5-232,2°С в присутствии кислорода и последующем коксовании .The known methods for curing raw briquettes from charcoal are heat treating briquettes at 190.5-232.2 ° C in the presence of oxygen and subsequent coking.
С целью повышени эффективности процесса и улучшени отвода тепла по предлагаемому способу производ т нагрев брикетов на подвижной решетке с толщиной сло 25,4- 91,4 см при подаче кислородсодержащего газа.In order to increase the efficiency of the process and improve the heat removal of the proposed method, briquettes are heated on a movable grid with a layer thickness of 25.4-91.4 cm when the oxygen-containing gas is supplied.
Иредлагаемый способ заключаетс в следующем .And the proposed method is as follows.
Сырые брикеты на движущейс решетке слоем толщиной 25,4-91,4 см подвергаю г термообработке. Дл этого их помещают в газы , содержащие 15% кислорода, а гор чий насыщенный кислородом газ (воздух), содержащий 21% кислорода, при 190,5-232,2°С проходит через движущийс слой брикетов с достаточно высокой скоростью, при которой отводитс тепло экзотермической реакции и предотвращаетс повышение температуры в брикетах выше 288-301,7°С.Raw briquettes on a moving grate with a layer thickness of 25.4-91.4 cm are subjected to heat treatment. To do this, they are placed in gases containing 15% oxygen, and a hot oxygen-saturated gas (air) containing 21% oxygen, at 190.5-232.2 ° C, passes through a moving layer of briquettes at a sufficiently high rate at which heat is an exothermic reaction and temperature rise in briquettes above 288-301.7 ° C is prevented.
Реакци по предлагаемому способу протекает с оптимальной скоростью, а скоростьThe reaction of the proposed method proceeds at an optimal rate, and the speed
газового потока достаточно высока дл отведени тепла, что позвол ет поддерживать температуру брикетов ниже точки воспламенени .the gas flow is high enough to remove heat, which allows the briquette temperature to be maintained below the ignition point.
Необходимое количество газа определ етс его температурой, составом, скоростью реакции и количество.м тепла, которое нужно отвести . Температура должна быть достаточно высокой дл инициировани реакции. Больша загрузка сырых брикетов, наход щихс при 82,2-92,2°С, может воспламен тьс при контакте с воздухом.The required amount of gas is determined by its temperature, composition, reaction rate and the amount of heat that must be removed. The temperature must be high enough to initiate the reaction. A heavy load of raw briquettes that are at 82.2-92.2 ° C can ignite on contact with air.
Дл сокращени времени реакции газ нужно нагревать до 190,5°С, но при этом он должен отводить тепло. Поэтому темцература газа не должна превышать 232,2°С. Иредпочтительно поддерл ивать температуру 210±8°С. Можно использовать нагретый воздух или газ, содержащий воздух в смеси с продуктамиTo shorten the reaction time, the gas must be heated to 190.5 ° C, but it must also remove heat. Therefore, the temperature of the gas should not exceed 232.2 ° C. It is preferable to maintain a temperature of 210 ± 8 ° C. You can use heated air or a gas that contains air mixed with products.
