A kind of power plant condenser descaling method

Abstract

The invention discloses a power plant condenser descaling method. The method comprises the following steps of S1, preparing descaling raw materials and equipment, specifically purchasing a sufficientamount of raw materials according to a cleaning solution formula, and purchasing at least two sets of equipment and pipelines for cleaning a pipeline loop, wherein including a circulating water pump,pipelines, a filter and a toughened glass pipeline; S2, preparing a cleaning solution; S3, arranging a descaling pipeline loop; S4, descaling; S5, carrying out descaling sewage treatment; S6, cleaninga condenser, specifically disassembling the descaling loop arranged in the S3 as soon as possible, rapidly flushing the part of the internal loop of the condenser with clear water, checking the corrosion situation of inner parts in the cleaning process, and replacing the parts without reaching the expected working effect; and S7, cleaning the pipeline loop. According to the method, in S6, a high-pressure water gun is used for flushing, so that the treatment on internal corrosion of the condenser is enhanced during using, and the situation that the cleaning is incomplete in the prior art is avoided.

Description

technical field [0001] The invention relates to the technical field of descaling of condensers, in particular to a method for descaling of condensers in power plants. Background technique [0002] A heat exchanger that condenses exhaust steam from a steam turbine into water, also known as a rehydrator. Condensers are mainly used in steam turbine power plants and are divided into water-cooled condensers and air-cooled condensers. A heat exchanger that condenses exhaust steam from a steam turbine into water, also known as a rehydrator. Condensers are mainly used in steam turbine power plants and are divided into water-cooled condensers and air-cooled condensers. In addition to condensing the exhaust steam of the steam turbine into water for reuse by the boiler, the condenser can also establish and maintain a vacuum at the exhaust steam of the steam turbine. [0003] Yet existing condenser descaling method step has many defectives such as: [0004] 1. In the prior art, only...

AI Technical Summary

Problems solved by technology

[0004] 1. In the prior art, only the conventional circulation is used in the descaling process of the condenser, and then the fresh water circulation is used after the circulation. However, the fresh water circulation is used for replacement, and in actual use, only the water circulation is used for cleaning because the interior is not impacted. In the case of cleaning, part of the internal rust residue cannot be effectively cleaned

[0005] 2. In the prior art, the condenser continues to be used after descaling, and it can be used directly after descaling. However, in the prior art, after descaling, its internal structure can no longer be used normally after descaling, then it may There will be failures in follow-up work, so it cannot meet the needs of existing technologies
