Activated carbon continuous sorption-desorption device for movable bed

Abstract

The invention discloses an activated carbon continuous sorption-desorption device for a movable bed. The device comprises an adsorber filled with granular active carbon, wherein an aggregate bin is in communication with the adsorber through an upright material sealing pipe, and continuously and slowly provides the granular active carbon into the adsorber; a regenerator is arranged below the adsorber by communicating with the adsorber through a first star-type material feeder; the granular activated carbon at the bottom of the adsorber continuously and slowly flows into the regenerator; the regenerator is in communication with a lifting pipe dryer by a second star-type material feeder; a first cyclone separator placed at the upper part of the aggregate bin is arranged at the upper end of the lifting pipe dryer; the granular activated carbon at the bottom of the regenerator is lifted by the lifting pipe dryer so as to continuously flow into the aggregate bin via the first cyclone separator; a waste gas inlet pipe and a waste gas outlet pipe are arranged on the adsorber; and a steam inlet pipe and a steam outlet pipe are mounted on the regenerator. By using the activated carbon continuous sorption-desorption device disclosed by the invention, the sorption-desorption process can be continuously carried out, thereby improving the sorption-desorption efficiency.

Description

technical field [0001] The invention relates to a device for treating exhaust gas using activated carbon, in particular to a continuous adsorption and desorption device for moving bed activated carbon. Background technique [0002] At present, aromatic toxic gases such as benzene and toluene, as well as volatile gases such as alcohols and lipids are often produced in the processes of industrial spraying, drying, shoemaking, and tanning. Most of the gases are toxic. If directly Discharge into the atmosphere is likely to cause serious pollution and waste a lot of resources. With the rapid development of technology, activated carbon or activated carbon fiber adsorption and desorption devices are generally used to treat waste gas, and the purified gas is discharged into the atmosphere, which not only reduces pollution to the atmosphere, but also recovers a large amount of organic resources. However, the structure of the activated carbon adsorption device in the prior art is rel...

AI Technical Summary

Problems solved by technology

However, the structure of the activated carbon adsorption device in the prior art is relatively simple, and the switching operation of multiple adsorption tanks is required to achieve the purpose of continuous operation, which occupies a large space and is prone to low adsorption and desorption recovery efficiency due to incomplete steam desorption. , higher cost of adsorption and desorption
