The invention belongs to the technical field of
radioactive waste treatment and relates to an in-
barrel vacuum
microwave drying system and method for radioactive wet wastes. The
drying system comprises a
drying barrel, a
demister, a filter, a condenser, a steam-water separator, a
vacuum pump, a
tail gas
continuous monitoring device and connecting pipelines; the drying
barrel is used for drying thewastes by
microwave heating; the
demister, the filter, the condenser, the steam-water separator and the
vacuum pump which are connected in sequence are respectively used for realizing demisting,
filtration, condensation, steam-water separation and vacuumizing treatment of evaporated
tail gases generated by drying; and the
tail gas
continuous monitoring device is connected with the condenser and is used for monitoring noncondensable gases in the evaporated tail gases and discharging qualified noncondensable gases into the air by the connecting pipeline connected with an outlet of the tail gascontinuous monitoring device. By using the drying
system and method disclosed by the invention, the rapid drying of various radioactive wastes can be realized, new substances are not introduced in a drying process, and the tail gases discharged after being dried almost have no any harmful effects on the environment.
