AI Technical Summary
The existing deaerators have a small contact area between steam and water and a single contact method, resulting in a mediocre deaeration effect and low deaeration efficiency.
An enhanced deoxygenation device for deaerators was designed, comprising a water tank, a shell, a spray pipe, an atomizing nozzle, a drain plate, a water distribution plate, a water guide plate, and a steam pipe. It increases the contact area and contact method between steam and water in multiple ways, uses the atomizing nozzle to form small water droplets, and allows steam to pass through multiple water distribution plates to contact the water, thereby enhancing the deoxygenation effect.
This results in a larger contact area and more contact methods between steam and water, significantly improving deoxygenation effect and efficiency, and reducing the corrosion risk of boiler equipment.
