In power plant operation, the cooling system plays a crucial role. In order to ensure the efficient, safe and long-term operation of power generation equipment, the control of circulating water quality is particularly critical.
Poly(dichloroethylene ether tetramethylethylenediamine) (WSCP), as a multifunctional cationic polyamine compounds, due to its good water solubility, chemical stability and bactericidal scale inhibition ability, more and more is used in power plant circulating water system purification and protection.
the main problems faced by the circulating water system
Power plant cooling water system is usually closed or semi-closed cycle, long operation is prone to the following problems:
Microbial growth: such as algae, bacteria, fungi proliferation, the formation of biofilm, affecting the heat transfer efficiency;
Inorganic salt scaling: calcium and magnesium ions precipitate into scale under high temperature environment, blocking heat exchangers and pipelines;
Corrosion problems: microbial metabolites or pH fluctuations are prone to trigger equipment corrosion, shortening service life;
Higher system energy consumption: the heat transfer efficiency deteriorates after the water quality drops, resulting in lower power generation efficiency and higher energy consumption.
The role of WSCP mechanism and performance advantages
1. Sterilization and inhibition of algae, to prevent the formation of biofilm
WSCP molecules contain a number of cationic quaternary ammonium groups, can quickly penetrate the cell membrane, destroy the microbial metabolic system, play a broad-spectrum bactericidal effect. Compared with traditional quaternary ammonium biocides, WSCP is more soluble in water, strong diffusion, especially suitable for large-scale circulating water system of distributed control.
2. Enhance flocculation, remove suspended impurities in water
WSCP has strong cation adsorption ability, can be quickly neutralized and polymerized with negatively charged suspended particles and colloidal impurities in the water to form larger flocs, enhance the settling speed and optimize the filtration process. This not only improves the water quality, but also reduces the burden of subsequent equipment.
3. Synergistic corrosion and scale inhibition, improve system stability
WSCP can also be used as a cationic modified component in the compounding system, which works synergistically with a variety of scale and corrosion inhibitors to form a dense protective film on the metal surface, effectively inhibit calcium and magnesium precipitate scaling and metal corrosion, and extend the service life of the equipment.
4. High temperature resistance, high salt resistance, adapt to harsh working conditions
Due to the high operating temperature of the power plant and the complexity of the water cycle, WSCP has good heat and salt resistance, and can maintain stable activity in high temperature, high hardness and high mineralization water, so it can adapt to the operating environments of various power plants (e.g., coal-fired, gas-fired, and nuclear power) cooling systems.
Application mode
WSCP is usually added into circulating water system in liquid form, and can be used alone or compounded with other water treatment agents.
