Generator internal cooling water membrane purification and alkalization control treatment device

Abstract

The invention relates to a membrane purification and alkalization control processing device for generator internal cooling water. A water inlet pipe (20) of the device is connected with a generator internal cooling water bypass (23); a water outlet of the device is directly returned to a generator internal cooling water tank (22); the pressure of inlet water, which enters the device, of the internal cooling water is detected by an onsite pressure gauge (1) which is mounted on an inlet pipeline; after entering the device, the generator internal cooling water enters an ion removing part. The device provided by the invention has advantages that the structure is simple, the cost is low, the conductivity of the internal cooling water is the lowest, a pH (potential of hydrogen) value is moderate, the content of copper ions is the lowest, the insulativity of a generator is furthest improved, and the running period is long. A method provided by the invention has advantages of being simple in technique, being convenient to operate and having a certain degree of automation.

Description

Technical field: [0001] The invention relates to an inner cooling water film purification and alkalization control treatment device for a generator. Background technique: [0002] Because the water internal cooling generator has the characteristics of large capacity, small size and light weight, it is widely used in large generator sets. There are too many accidents caused by the poor quality of the inner cooling water of the water inner cooling generator set. In order to prevent such accidents, a lot of research has been done on the inner cooling water quality and copper corrosion mechanism and anti-corrosion methods at home and abroad, and the conclusions are drawn: a. The lower the conductivity of the inner cooling water, the better the electrical insulation performance, and there will be no insulation faults such as electrical flashover; b. The root cause of copper corrosion is the presence of dissolved oxygen and dissolved carbon dioxide in the inner cooling water. Val...

AI Technical Summary

Problems solved by technology

Therefore, the coil temperature increases, which will lead to accelerated corrosion of copper

If it is not controlled early, it will cause local overheating and damage to the generator bar, and in severe cases, insulation breakdown will cause grounding accidents
