Water cap for macroporous resin adsorption column

Abstract

The invention relates to a water cap for a macroporous resin adsorption column, the water cap comprises a hollow flow guide pipe (1) with a flow guide hole (11) in the center, the outer wall of the flow guide pipe (1) is provided with an external thread (12), and the upper part and the lower part of the flow guide pipe (1) are respectively provided with a filtering and flow guide device and a fastener (7) which are in threaded connection; the filtering and flow guiding device comprises a filtering plate (3), a flow guiding shell and a screen; wherein the periphery of the filtering plate (3) isin threaded connection with the flow guide pipe (1) through a filter plate connecting part (31) with an L-shaped section, the flow guiding shell comprises an annular base (21) and a plurality of flowguide plates (22) arranged around the base (21), and a circular screen (5) is connected to the tops of the flow guide plates (22) in a clamped mode through protrusions on the periphery. The water capis reasonable in design, simple in structure, capable of effectively removing fine-particle-size resin in the backwashing process and avoiding blockage of a water cap, convenient to disassemble and capable of effectively improving the operation efficiency.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a water cap for a macroporous resin adsorption column. Background technique [0002] Macroporous adsorption resin is a highly cross-linked, porous, non-ion-exchange group, infusible and insoluble organic polymer granular material with a high specific surface area, so it has excellent adsorption capacity. COD of wastewater Cr , heavy metal ions, etc. have good selective adsorption. [0003] In order to effectively intercept the resin and ensure the uniform distribution of the material liquid, a distribution water cap is set in the adsorption column. In addition, the ion exchange column must keep the resin loose in the column, and the fine particle size resin produced during the operation must be discharged through the water cap during the recoil process. At present, the traditional water caps of the same type cannot meet the conditions of use due to their small gaps, an...

Problems solved by technology

At present, the traditional water caps of the same kind cannot meet the conditions of use due to the small gaps. At the same time, they must be removed and washed irregularly. The removal and cleaning process is cumbersome, which affects the working efficiency.
