Background technique
Solid product of the coal after low temperature distillation is known as semicoke.Semicoke can be used as industrial chemicals and clean fuel.Destructive distillation institute
The hot semicoke produced need to cool and could transport and store after (quenching).Currently, the quenching that low order dry distillation of coal industry generallys use
Method is divided into wet quenching and Dry Quenching.
Wet quenching is directly to be poured into water or water is sprayed on semicoke to make its cooling for hot semicoke.This method investment
Low, operation is easy, but cannot recycle heat, and water consumption is big, generates a large amount of waste water and exhaust gas, causes serious dirt to environment
Dye, belongs to the technology gradually eliminated.Dry Quenching be using cold inert gas and hot semicoke direct contact heat transfer, or every
From used under state water or cryogenic gas for the cooling hot semicoke of the indirect heat exchange method of cooling medium.Dry Quenching can reduce environment
Pollution improves burnt quality, and recovery section heat, but technology is more complex, high investment.Currently, Dry Quenching has obtained
More and more applications, also emerge more and more new technology new inventions, but still come with some shortcomings.For example, patent of invention
Application CN201610919124.9 discloses a kind of cooling half coke installation of cylinder, which sets heat exchange cooling to be horizontal, internal
Pipe group, the equipment that runs under continuous rotation state, cooling medium pass through tube wall and outside in cooling tube group in flow process
