Description

technical field [0001] The invention belongs to the technical field of on-line monitoring of hydrogen conductivity in a water vapor system, and relates to an intelligent diagnosis and processing system for abnormal hydrogen conductivity. Background technique [0002] The hydrogen conductivity is the conductivity measured after the water sample is treated with a hydrogen-type strong acid cation exchange resin. The cation exchange resin is mainly used to remove the Na in the water sample. + , NH 4 + and other cations, which only characterize the anions left in the water sample (Cl - , SO 4 2- 、PO 4 3- etc.), can better reflect the harmful anion content in the water sample, and is an important indicator to reflect the water vapor quality in the quality monitoring of the water vapor system in the electric power, steel, chemical and other industries. [0003] When the hydrogen conductivity is measured online, it is necessary to pass the water sample through the hydrogen-ty...

Problems solved by technology

When the hydrogen conductivity of a measuring point in the water vapor system increases abnormally, the water vapor quality monitoring system will often give an alarm or even cause some system protection functions to operate, and the operator must combine the measurement data upstream and downstream of the abnormal measuring point to judge the end Is it caused by the deterioration of the water vapor quality of the measuring point itself or the failure of the hydrogen-type strong acid cation exchange resin due to the exhaustion of its exchange capacity? The reason for the abnormal water quality of the measuring point is judged by the operating status of the type strong acid cation exchange resin. This process is often time-consuming and labor-intensive, and it is easy to delay the timing of on-site treatment of the problem, resulting in greater system losses and hazards.

[0004] On the other hand, after running for a period of time, the hydrogen-type strong-acid cation-exchange resin becomes invalid due to the exhaustion of its exchange capacity. It is necessary to manually remove the hydrogen-type strong-acid cation-exchange resin in the ion-exchange column to regenerate and replace it with a new resin. Putting it into HCL for regeneration will produce more acidic waste liquid during the regeneration process. At the same time, the entire regeneration process is complicated and requires a lot of work, which requires a lot of manpower

In the process of resin regeneration and replacement, the monitoring of hydrogen conductivity is generally always in an abnormal state, which also has an adverse effect on the overall data monitoring of the water vapor system
