Activated carbon adsorption device for refining waste salt

Abstract

The invention discloses an activated carbon adsorption device for refining a waste salt, the activated carbon adsorption device comprises an activated carbon adsorption tower I and an activated carbonadsorption tower II, the activated carbon adsorption tower I and the activated carbon adsorption tower II are both obtained by welding of a barrel body, a sealing head and a bottom plate; a backwashing water discharge pipe, a water distribution pipe, a back-flushing air washing pipe, an aeration pipe, a drainage pipe and a back-flushing water washing pipe are sequentially arranged in the cylinderbody of the activated carbon adsorption tower I from top to bottom, the inner wall of the bottom plate is filled with a ceramic ring cushion layer, a ceramic ball cushion layer is filled between theceramic ring cushion layer and the aeration pipe, and an activated carbon layer is filled at the horizontal position of the aeration pipe; wherein the two activated carbon adsorption towers are used,the two-time adsorption is realized by utilizing the liquid level difference of the two activated carbon adsorption towers, the adsorption effect is good, meanwhile, the automation degree of the adsorption process is high, only a salt solution to be treated needs to be continuously injected from the water distribution pipe, the liquid level difference is utilized to enable the salt solution to beautomatically discharged from a liquid outlet after two-time filtering, the labor intensity of workers is greatly reduced, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of industrial waste salt treatment, in particular to an activated carbon adsorption device for refining waste salt. Background technique [0002] In the pesticide processing and production industry, a large amount of waste salt is produced every year, and the treatment methods of industrial waste salt are divided into outsourcing treatment, self-incineration by enterprises, and industrial recycling after oxidation treatment of waste salt. In terms of economy, environmental protection and other aspects, it is the most ideal treatment method to oxidize waste salt and then recycle it. Most of the existing waste salt oxidation treatment processes are to prepare industrial waste salt into brine, then oxidize through the oxidation tower in turn, then adsorb through the activated carbon adsorption layer, and finally obtain refined brine after adsorption through the macroporous resin adsorption tower. saline soluti...
