Benefits of technology

This patented technology improves upon existing methods for reusing or recycling ion-exchange resins used in electrical energy generation systems (EES). It eliminates the need for harmful substances like chlorine gas that have been added during production processes. Additionally, it simplifies the process of replacing damaged parts after they've become worn out due to environmental factors such as temperature changes over time without requiring excessive cleanup efforts. Overall, this new system provides more efficient and effective EES devices while reducing negative impacts on their ecosystem through its ability to recover and reuse certain materials found within them.

Problems solved by technology

This patented technical problem addressed in this patent relates to improving the efficiency and effectiveness of electric regulation methods for treating contaminants from wastewater or other sources containing harmful substances (such as chlorine) that can be difficult to remove with traditional techniques like filtrations alone.

Abstract

The invention provides a membrane-free ion exchange resin electric regeneration device based on a filter element electrode. The membrane-free ion exchange resin electric regeneration device comprisesa cylindrical shell; a supporting layer, which is arranged on the inner side of the shell and is integrated with the shell through casting; filter cloth; a net-shaped cathode, wherein the filter clothand the net-shaped cathode are tightly attached to the inner side of the supporting layer in sequence; and a filter element anode, which extends into the shell from a cover plate above the shell along the central axis direction of the shell. The filter element anode is fixedly connected to a bottom plate above the shell through a fixing flange; an ion exchange resin bed layer is tightly filled inthe shell; the filter element anode is connected with the anode of a DC power supply, and the net-shaped cathode is connected with the cathode of the DC power supply. The device is simple in structure and easy to operate, and meanwhile, the problem of hydraulic bias caused by structural difference of multiple groups of filter element electrodes is avoided.
