AI Technical Summary
The existing ammonia water preparation equipment has insufficient mixing degree between ammonia gas and water, resulting in low absorption efficiency, low production rate, and the equipment cannot meet the needs of preparing ammonia water from liquid ammonia.
The absorption tower employs a gas guiding component and a liquid guiding component. The gas guiding component draws out ammonia gas from the bottom and generates an aeration effect, while the liquid guiding component sprays liquid from the top to enhance the contact between water and ammonia gas. Combined with a vaporizer, ammonia water can be prepared in two ways: liquid ammonia and gaseous ammonia.
It improves the ammonia absorption efficiency, increases the ammonia water production rate, and expands the application range of the device, enabling the preparation of ammonia water through both liquid and gaseous ammonia.
