The invention discloses a novel
fluidized bed semicoke production
system and a process thereof. The novel
fluidized bed semicoke production
system comprises a
drying system and a
dry distillation system, wherein the feed end of the
drying system is connected with a feeding device, the
tail gas of the
drying system is reclaimed after passing through at least
one stage of drying and dust removing device, and the drying system is connected with a heat source; both the
discharge end of the drying system and the
discharge end of the drying and dust removing device are connected with the feed end of the
dry distillation system; and after passing through at least
one stage of dust removing device, one path of the
pyrolysis gas of the
dry distillation system is used as the fluidizing medium of the dry
distillation system for closed circulation, one part of the other path passing through at least
one stage of condensing device is evacuated, the other part is burnt and then used as the heat source of the system, and the
discharge end of the dry
distillation system is connected with a finished product area. After lignite is processed and upgraded by adopting the technology, low-temperature semicoke as
solid fuel and low-temperature
coal tar as a derivative with good stability, low
sulfur content and
high heat value can be produced. Meanwhile, the novel
fluidized bed semicoke production system has
high heat utilization ratio, no environment
pollution and high comprehensive utilization level of resources, can be continuous and stable to operate and realizes large-scale production.
