The standards and mechanisms of dirt -resistant agents of electric plants are as follows: as follows:
1. Standards: The circulating water resistant agent of power plants shall refer to the relevant national standards and the standards of the power industry, such as the “Technical Regulations for Power Station Water Supply and Circular Water Treatment” (DL/T 5142-2016). These standards usually include regulations on the composition, use method, dose control, and water quality index requirements of the stool resistant agent.
2. Role mechanism: ATMP of circulating water in power plants is mainly used by the following machines:
(1) Salvants through decentralization: Surface active agents and decentralizers in the stool resistant agent can reduce the surface tension of inorganic salt in the water and disperse them into small particles or colloids to prevent their crystallization precipitation and inhibit their crystallization. The formation of scale.
(2) Aquattopo -resistant agent: The passivation agent in the stuffing agent can react with the metal ions in the water, forming a stable complex, hindering the crystallization and deposition process of metal ions, thereby avoiding the scale of scale. form.
(3) Square resistant agents can slowly release the active substances in the circulating water system through a slowdown effect: The active substance is slowly released in the circulating water system, forming a layer of protective film covered on the surface of the tube wall to prevent scale adhesion and blockage.
(4) Dirt -resistant agent through alkaline regulation: The alkaline substances in the dirt resistant agent can adjust the pH value of circulating water, maintain it within the appropriate range, so that the inorganic salts in the water are difficult to crystallize and precipitate, and reduce the tendency of scale formation.
The mechanism of the use of stuffing agents in power plants is multi -faceted. Through the comprehensive role of the above mechanism, it can effectively suppress the formation and deposition of scale, maintain the normal operation of the circulating water system, improve the heat exchange efficiency of the equipment, extend the use of use life. According to the specific circulating water quality, process conditions, and equipment requirements, the use of stool resistance agents under a reasonable dose control to ensure its effects and safety.
