蒸汽发生器排污系统
By using a spiral guide plate and adsorption column in the steam generator blowdown system, the problems of short swirling paths and incomplete separation were solved, achieving efficient steam-water separation and wastewater purification, reducing the water content of secondary steam, protecting the separator, and simplifying subsequent treatment.

AI Technical Summary
In existing steam generator blowdown systems, the kinetic energy of wastewater from the tangential inlet generates a short swirling path, and the swirling intensity decays rapidly, resulting in incomplete steam-water separation, high moisture content in the secondary steam, and easy scaling and corrosion of the separator, as well as low efficiency in capturing tiny droplets.
The expansion container employs multiple guide plates arranged in a spiral pattern, combined with an adsorption column and filter elements. Wastewater spirals down along the guide plates, while the gas phase generates a swirling flow in the middle of the expansion container and crosses into the adsorption column. The adsorption column absorbs the droplets, the first filter element further intercepts secondary steam, and the second filter element treats impurities in the wastewater.
It improves the steam-water separation time and efficiency, reduces the water content of secondary steam, reduces scale and corrosion in the separator, enhances the ability to handle small droplets, and provides preliminary purification of wastewater for subsequent use.
