Description
Известен способ непрерывного полукоксовани углей с применением чугунных шаров в качестве теплоносител . Недостатком этого способа вл етс большой вес чугунных шаров на 1 кг полукоксуемого угл , а следовательно, большой расход энергии, затрачиваемой на рециркул цию чугунных шаров дл полукоксовани углей.The known method of continuous semi-coking of coals with the use of cast-iron balls as a heat carrier. The disadvantage of this method is the large weight of pig-iron balls per 1 kg of semi-coked coal, and, consequently, a large consumption of energy spent on recirculation of iron balls for semi-coking of coal.
Предлагаемый способ полукоксовани угл отличаетс от известных тем, что, с целью уменьшени расхода энергии на циркул цию теплоносител и улучшени теплопередачи, шары выполн ютс полыми с заполнением их различными сол ми или их смесью.The proposed coal coking method is different from the known ones in order to reduce energy consumption for heat carrier circulation and improve heat transfer, the balls are made hollow with filling them with different salts or their mixture.
При замене чугунных шаров на полые стальные шары с солевым заполнением (NaCl - 50% + CaCl2 - 50%) вес шаров на 1 кг полукоксованного угл значительно снижаетс , а расход энергии дл циркул ции теплоносител уменьшаетс примерно в три раза.When replacing cast iron balls with hollow steel balls with salt filling (NaCl - 50% + CaCl2 - 50%), the balls weight per 1 kg of semi-coked coal is significantly reduced, and the energy consumption for circulating coolant decreases about three times.
Теплота плавлени (кристаллизаци ) этой смеси солей составл ет 88 ккал/кг. В процессе теплопередачи от нагретых шаров с солевым заполнением к полукоксуемому углю используетс не только теплота охлаждени солевой смеси в пределах температур 800-500°, но также и теплота кристаллизации солевой смеси.The heat of fusion (crystallization) of this mixture of salts is 88 kcal / kg. In the process of heat transfer from heated balls with salt filling to semi-coking coal, not only the heat of cooling of the salt mixture within the temperature range of 800-500 ° C is used, but also the heat of crystallization of the salt mixture.
Преимуцхеством применени солевого теплоносител , заключенного в сферическую оболочку, вл етс также его дешевизна по сравнению с чугунными шарами.The advantage of using a salt heat carrier enclosed in a spherical shell is also its cheapness compared to cast-iron balls.
