Purging method of super high-rise steam pipeline and cooling water tank used by purging method

Abstract

The invention discloses a purging method of a super high-rise steam pipeline and a cooling water tank used by the purging method. The purging method conducts purging according to the following steps of finding out parameters of the steam pipeline to be purged, designing the cooling water tank, manufacturing the cooling water tank, mounting the cooling water tank, performing purging treatment and verifying a purging result. When steam purging is carried out, a large amount of steam is prevented from overflowing. The problems of noise pollution and false fire alarms caused by exhaust of a largeamount of steam in the prior art are effectively solved, and meanwhile, pollution of the steam containing impurities to the environment is avoided. According to the purging method, independent sectional flushing with tap water is not needed, so that sectional flushing equipment, materials, labor cost and time are saved. The steam generated during boiler debugging and trial operation can be utilized during purging, and purging resources are saved. The method is particularly suitable for cleaning the steam pipeline of a super high-rise building.

Description

technical field [0001] The invention relates to a purging method of a super high-rise steam pipeline and a used cooling water tank, and belongs to the technical field of building electromechanical equipment maintenance. Background technique [0002] In the prior art, there are two main methods of flushing steam pipelines: tap water flushing and steam blowing. For super high-rise buildings, the height is more than 100 meters. If tap water is used for flushing, a booster pump needs to be added, and due to the high hydrostatic pressure, it needs to be flushed in sections under consideration of safety factors, which consumes a lot of man-hours and labor costs. The use of steam purging does not need to be divided into sections, which is safe and reliable. However, the existing steam purging method is to discharge the steam outdoors, which has the following problems: First, the periphery of the building is closed by glass curtain walls during purging. If the steam is discharged in...

Problems solved by technology

For super high-rise buildings, the height is more than 100 meters. If tap water is used for flushing, a booster pump needs to be added, and due to the high hydrostatic pressure, it needs to be flushed in sections considering safety factors, which consumes a lot of man-hours and labor costs.

The use of steam purging does not need to be divided into sections, which is safe and reliable. However, the existing steam purging method is to discharge the steam outdoors, which has the following problems: First, the periphery of the building is closed by glass curtain walls during purging. If the steam is discharged indoors, it cannot Second, if it is discharged through the louvers through the equipment layer, the impurities and dirt in the pipeline will contaminate the glass curtain wall, which is difficult to clean; the third is that the steam is purged at a flow rate of more than 30m / s when purging, and there will be a loud howling sound. Cause noise pollution; Fourth, the white water mist generated by a large amount of steam exhausted outside may cause false alarms of fire
