Power generator internal cooling water oxygen removal or electrolemma microalkalination treatment device and its treatment method

Abstract

This invention relates to processing equipment for cold water removing oxygen or electrolemma micro-alkalifying in power generator and its processing method. It relates to water processing equipment and its processing method. It has solved problems of disqualified cold water quality, hollow copper guide wire corroding in about power generator. Its second osculum of penstock connects with rotormeter inlet by primary flange. There is check valve at space between up and below flange plate of primary flange. 5%-10% inside cold water enters in equipment inlet valve, inlet pressure gauge, check valve, and rotormeter from equipment inlet, flow in deionizer, electrolemma micro-alkalifying equipment or deaerator respectively. This processed inside cold water return to inside cold water tank of power generator through resin catcher, equipment export valve, outlet pressure gauge. This equipment has advantages of simple structure, low cost, lowest electric conductivity of inside cold water, least dissolved oxygen, suitable PH, minimum copper content, utmost to increase power generator insulation, and long cycle of operation.

Description

technical field [0001] The invention relates to a water treatment device and a treatment method thereof. 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 inner cooling water in water inner cooling generator sets. 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. Divalent copper ions can accelerate corrosion; c. Corros...

AI Technical Summary

Problems solved by technology

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

②If it is not controlled early, it will cause local overheating and damage to the generator wire rod, and in severe cases, insulation breakdown will cause grounding accidents

Its disadvantages are complex system, large floor area, troublesome operation, especially the alarm phenomenon of exceeding the standard of conductivity often occurs.

In the RNa+ROH operating state, if the make-up water quality is poor, there will be a large amount of Na + Short-term leakage will cause the conductivity of the inner cooling water to rise rapidly, which will increase the leakage current and loss. In severe cases, electrical flashover will occur, which will destroy the normal circulation of the inner cooling water and even damage the equipment.

[0007] The problem with the method of adding condensed water to the internal cooling water is that the open internal cooling water system tends to volatilize ammonia and dissolve carbon dioxide, which reduces the pH value of the internal cooling water

[0010] The single small mixed bed RNa+ROH method has the problem that the conductivity of the water quality is easy to rise, and the oxygen corrosion cannot be completely eradicated.

[0011] The first-stage desalination method has a long operation period, the conductivity of water quality is easy to rise, and the problem of oxygen corrosion cannot be completely eradicated
