Steam condenser copper tube foam leak-detecting liquid

Abstract

This is a check the leakage liquid method by the foam of copper rube in the steamer. It is a special solution formula to form the foam. its features are: The function of against the deposit is strong, and the foam can lasting longer time and its viscosity degree is higher.

Description

Technical field

[0001] The invention relates to a solution formula for leak detection of a copper tube of a condenser in a power system. Background technique

[0002] After many years of use in heat exchangers and copper tubes of condensers in thermal power plants, due to industrial pollution of water quality and increase in the concentration ratio of circulating water, it is easy to cause pitting corrosion of copper tubes in condensers, and corroded copper tubes will cause Circulating water leaks to the steam side of the condenser, resulting in a decline in the quality of condensed water, accelerating the corrosion and scaling of the boiler heating surface tubes, often causing boiler tube bursts, resulting in unplanned shutdown accidents. In order to solve this problem, it is necessary to replace copper pipes or plugged pipes, and to replace copper pipes or blocked pipes, it is necessary to accurately select leaky pipes. The usual method is to use the candlelight leak dete...

Embodiment Construction

[0005] specific implementation plan

[0006] The supporting technical solutions are divided into: ①Open the manhole door, clean up the sundries on the condenser tube sheet and nozzle; ②Apply the prepared solution foam quickly and evenly on the tube sheet with a special wiper or leak detector, Make sure each spout is filled with foam. Since the steam side of the condenser in operation is under negative pressure, when a leak occurs in a certain pipe, negative pressure will appear at the nozzle, and the foam coated on the nozzle will be sucked into the pipe. When this situation occurs, Block the root pipe with a special plug for leakage statistics.

[0007] The copper pipes that have been statistically recorded are leaky pipes, which can be replaced or blocked according to the leakage situation.

[0008] The patented invention can carry out construction without stopping the machine, without drying the copper pipe, with short time, high accuracy and thorough search. It is mainl...
