Control system for automatically controlling hardness of produced water of sodium ion exchanger and control method thereof

Abstract

The invention belongs to the technical field of industrial softened water application, and discloses a control system for automatically controlling the hardness of produced water of a sodium ion exchanger and a control method thereof, which ensure that the sodium ion exchanger continuously operates according to operation steps and operation time before the system is powered off after the system ispowered off and power supply is recovered. A softened water storage tank water level detection function is achieved, when the water level exceeds the limit, alarm information is displayed, and the system is shut down; the hardness composite electrode is adopted to automatically detect the effluent hardness of the sodium ion exchanger, and a corresponding control algorithm is adopted to automatically adjust the operation time of bed loosening, regeneration and cleaning steps according to the detection result, so that the hardness of produced water is ensured to meet the hardness index of softened water, and the sodium ion exchanger is ensured to be in an economic and efficient operation state. The system suitable for realizing pipeline switching of each step through a multi-channel valve and realizing pipeline switching of each step through an electromagnetic valve. The line fault detection of each electromagnetic valve is realized; and when the valve has a line fault, the system is shut down, and alarm information is displayed.

Description

technical field [0001] The invention belongs to the technical field of industrial softening water application, and in particular relates to a control system and a control method for automatically controlling the hardness of water produced by a sodium ion exchanger. Background technique [0002] At present, the operation controller of the sodium ion exchanger can only realize the semi-automatic operation of the sodium ion exchanger. On the one hand, it cannot automatically detect the hardness of the produced water of the sodium ion exchanger, and automatically adjust the running time of each step according to the detected hardness of the produced water. , can only use the traditional chemical reagent detection method to detect the hardness of the produced water, and then manually adjust the running time of each step, which has poor real-time performance; on the other hand, the current sodium ion exchanger operation controller has poor adaptability and cannot adapt to various t...

AI Technical Summary

Problems solved by technology

[0004] To sum up, the problems existing in the existing technology are: the current water softening method for industrial water is manually set and adjusted continuously according to the hardness of the produced water. It wastes resources, pollutes the environment, and cannot realize the economical, efficient and reliable operation of sodium ion exchangers
