Treatment device and purification system for simultaneously treating VOCs (Volatile Organic Compounds) and waste activated carbon

The utility model relates to the field of air pollution and solid pollution control, in particular to a treatment device and a purification system for simultaneously treating VOCs (Volatile Organic Compounds) and waste activated carbon. The treatment device comprises a variable-diameter limited fluidized bed reactor, a feeder used for adding waste activated carbon and/or a catalyst, a separator and a filter, the feeder is connected with a dense-phase section of the variable-diameter limited fluidized bed reactor, and the separator and the filter are both arranged on a dilute-phase section of the variable-diameter limited fluidized bed reactor and connected with the dilute-phase section. And the separator is communicated with the filter. According to the device, VOCs waste gas with different concentrations can be purified to be below 10mg/Nm < 3 >, the purpose of ultralow emission of the VOCs waste gas is achieved, meanwhile, various kinds of waste activated carbon or waste active coke can be treated, the poll
