AI Technical Summary

Technical Problem

The filling speed of the cold water ion exchange resin in the existing condenser is relatively slow, and it is easily contaminated during the filling process, which affects the effluent water quality of the ion exchanger and the stable operation of the unit.

Method used

A negative pressure, non-destructive resin filling system for a condenser was designed. Through a negative pressure circulation system and automated operation, a circulating water pump is used to create negative pressure, which draws the resin into the ion exchanger without damage. The system integrates conductivity and pressure monitoring to reduce the risk of contamination and supports remote control and mobile operation.

Benefits of technology

It improves resin filling efficiency, reduces the possibility of resin contamination, ensures the quality of effluent from the ion exchanger and the stable operation of the unit, and achieves automation and safety enhancements.

Abstract

This application provides a negative pressure, non-destructive resin filling system and method for a condenser. The system includes a resin filling device with a device inlet, a resin outlet, a resin filling hopper, and a circulating water pump. The bottom outlet of the resin filling hopper is connected to the resin outlet, which is connected to the resin filling port of an ion exchanger via a pipe. The device inlet is connected to the drain outlet of the ion exchanger via a pipe. The device inlet is connected to the top of the resin filling hopper via a pipe. A circulating water pump is installed in the pipe between the device inlet and the top of the resin filling hopper to pump the internal cooling water of the ion exchanger out of the drain outlet to create a negative pressure inside the ion exchanger, thereby drawing the resin from the resin filling hopper into the ion exchanger without damage through the resin filling port. After the system is filled with water, the circulating water pump is started to achieve negative pressure, allowing the circulating water to carry the resin from the resin filling hopper into the exchanger without damage, completing the automated filling process.
