Method for effectively cleaning circulating water system online

Abstract

The invention relates to the technical field of circulating water system cleaning, and discloses a method for effectively cleaning a circulating water system online. The method comprises the followingsteps that firstly, a joint pipeline on a water outlet pipeline of the circulating water system is connected to a water storage tank through a guide pipe, meanwhile, the water yield of the circulating water system is increased, after the guide pipe is conducted by a valve, part of water enters the water storage tank to be stored, meanwhile, water continues to be supplied to water consumption equipment, and more water is stored in the water storage tank; and secondly, after the valve of the joint pipeline of the water outlet pipeline is closed, the guide pipe through which the water storage tank is connected with the joint pipeline of the water outlet pipeline is disconnected. According to the method for effectively cleaning the circulating water system online, the water storage tank can be connected to the circulating water system, enough treated water is stored in the water storage tank between cleaning devices, the requirements of he water consumption equipment can be met when the system is cleaned, meanwhile, the water bypasses the circulating water system and then is connected to the water consumption equipment, and when the circulating water system is cleaned, normal water ofthe water consumption equipment can be guaranteed to clean the circulating water system.

Description

technical field [0001] The invention relates to the technical field of circulating water system cleaning, in particular to an effective online cleaning method for a circulating water system. Background technique [0002] At present, circulating water has been used in power plants, chemical plants and many heat exchange equipment for a long time. The water volume is huge and the economic cost is high. Due to the heat dissipation and evaporation of the circulating cooling water, the content of various minerals and ions in the water is continuously concentrated and increased, and precipitated and deposited on the heat transfer surface, which makes the thermal conductivity of the heat exchanger worse, the heat transfer efficiency is reduced, and the energy consumption is increased. In severe cases It will cause pipe blockage, water flow reduction and corrosion under scale. [0003] Therefore, the circulating water system needs to be cleaned regularly during use, and the circula...

[0002] At present, circulating water has been used in power plants, chemical plants and many heat exchange equipment for a long time. The water volume is huge and the economic cost is high.

Due to the heat dissipation and evaporation of the circulating cooling water, the content of various minerals and ions in the water is continuously concentrated and increased, and precipitated and deposited on the heat transfer surface, which makes the thermal conductivity of the heat exchanger worse, the heat transfer efficiency is reduced, and the energy consumption is increased. In severe cases It will cause pipe blockage, water flow reduction and under-deposit corrosion

[0003] Therefore, the circulating water system needs to be cleaned regularly during use, and the circulating water system stops working when cleaning is required. During this process, the water supply equipment cannot be supplied with water, which will cause the equipment in the factory to fail to work normally. Affect the production work of power plants or chemical plants
