AI Technical Summary

Technical Problem

Existing ion filters are complex in structure and bulky in size, making them unsuitable for installation in small industrial or scientific research equipment with limited space. The resin replacement and regeneration process is cumbersome, affecting the continuous operation of the system, and the resin inside the filter element is prone to leakage.

Method used

This modular ion filter allows for quick filter cartridge replacement via a clamp connection between the upper and lower housings. It incorporates a stainless steel perforated plate and wire mesh flow-limiting structure to prevent resin leakage. The top-mounted installation method is suitable for space-constrained applications and low-flow-rate applications.

Benefits of technology

It enables convenient installation and removal of filter elements, shortens maintenance time, improves operating efficiency and sealing performance, adapts to various installation methods, and is suitable for application scenarios with limited installation space.
