Abstract

The invention discloses a fluidized bed gas adsorption-desorption system and a treatment method thereof. The system includes an adsorption fluidized bed, a regeneration fluidized bed, an adsorption side gas-solid separator, a desorption side gas-solid separator and a feed divider. The adsorption fluidized bed has an adsorbent inlet, a to-be-treated gas inlet, a first returned material inlet and a first mixture outlet. The adsorption side gas-solid separator is connected to the first mixture outlet. The regeneration fluidized bed has a second returned material inlet, a desorption gas inlet, and a second mixture outlet. The desorption side gas-solid separator is connected to the second mixture outlet. The feed divider has a feed inlet, an adsorption side divided material outlet and a desorption side divided material outlet, the feed inlet is connected to an adsorption side solid-discharge port of the adsorption side gas-solid separator, the adsorption side divided material outlet is connected to the first returned material inlet, and the desorption side divided material outlet is connected to the second returned material inlet. The system provided by the invention is easy to operate, the system treatment ability is enhanced, and the adsorption efficiency, adsorption economical efficiency and operation continuity are improved.

Description

technical field [0001] The invention relates to the technical field of fluidized bed gas adsorption, in particular to a fluidized bed gas adsorption and desorption system and a treatment method thereof. Background technique [0002] In industrial adsorption reactors, in order to control the reactor pressure drop, adsorption efficiency and adsorption economy, the superficial gas velocity is usually controlled at about 0.1-0.6m / s, and the bed height is controlled at about 3-5m. In order to achieve the purpose of industrial continuous production, the adsorption unit is often equipped with multiple (usually 3 to 5) adsorption reactors, one reactor is used for adsorption, one is used for adsorbent regeneration, one is used for adsorbent drying and cooling, and the rest are used for standby. The three reactors used are switched back and forth manually or mechanically. [0003] At present, the common reactors for industrial adsorption are fixed bed, rotating bed and moving bed. Th...
