Problems solved by technology

At present, the components of commonly used corrosion and scale inhibitors are too single. When the hardness, alkalinity and chloride ion content of reclaimed water are high, it is difficult to achieve good corrosion and scale inhibition effects, and cannot meet the requirements of the circulating water system.

Abstract

The invention discloses a dirt remover for a water circulation system, belonging to the technical field of combustion. The dirt remover for the water circulation system, provided by the invention, can quickly remove dirt in the water circulation system, wherein the dirt in the water circulation system can be thoroughly removed in the shortest time of 23min; and meanwhile, the dirt remover can play a role in inhibiting dirt for a long time, wherein the longest dirt inhibiting time can be 178 days. The utilization efficiency of the water circulation system can be greatly increased, thereby increasing the production efficiency and reducing the equipment operation and maintenance cost.

Description

technical field [0001] The invention relates to a scale inhibitor for a water circulation system, which belongs to the technical field of combustion. Background technique [0002] Thermal power plants are large industrial water users, and the water consumption of their circulating cooling systems accounts for about 70%-80% of the total water consumption. Using recycled water as a supplementary water source for their circulating cooling systems can greatly reduce the use of conventional water sources and achieve large-scale water conservation. Therefore Doing a good job in the treatment of circulating cooling water can greatly reduce the power generation cost of thermal power enterprises. [0003] Corrosion and scale inhibitors are a kind of water treatment agent commonly used in water circulation cooling systems. Extend the service life of equipment and improve the economic benefits of thermal power enterprises. At present, the components of commonly used corrosion and sca...
