Working principle of high gravity ammonia removal equipment

The principle of ultra-gravity deamination equipment is based on the strengthening effect of centrifugal field on mass transfer process, which is mainly achieved through the following mechanisms:
1. Ultra-gravity field formation and mass transfer strengthening
(1) The equipment generates a centrifugal field hundreds to thousands of times greater than gravity through a high-speed rotating rotor or packed bed, dispersing the liquid into micron to nanometer liquid film, liquid filaments or droplets, forming a huge and constantly updated gas-liquid contact interface.
(2) Under the action of centrifugal force, liquid and gas flow in the opposite direction at a high relative speed, which strengthens the interphase mass transfer efficiency and reduces the height of the mass transfer unit to 1/10 of the traditional tower equipment.
2. Multi-factor synergistic deamination effect
(1) Heating desorption: Heating dilute ammonia water promotes the desorption of ammonia from the liquid phase.
(2) Vacuum adjustment of volatility: Using the vacuum system to reduce the operating pressure, change the relative volatility of ammonia and water, and promote the escape of ammonia.
(3) Countercurrent gas stripping: The gas is countercurrently purged in the liquid phase in a supergravity environment to further strip off the ammonia molecules.
3. Equipment structure optimization
(1) Adopt a baffled supergravity bed, which integrates distillation and absorption functions, and realizes multiple baffled contacts between gas and liquid through a rotating packed bed to improve separation efficiency.
(2) Compared with traditional tower equipment, a 1.2-meter-high supergravity equipment can achieve the separation effect of a 15-meter traditional distillation tower, greatly reducing the floor space.
4. Product separation and recovery
The ammonia content of the residual liquid after treatment can be reduced to below 0.05%, and 15-20% of concentrated ammonia water or ammonia gas can be recovered as industrial raw materials.
