Ammonia nitrogen air stripping tower

1, the working principle:

SST series ammonia recovery tower is two reverse flow Packing absorber, the general operation of the twin towers in series, in order to improve the recovery of the ammonia concentration.

Ammonia from the intake below the rim of the tower tangentially into the purification column, under the dynamic action of the fan, quickly filled the air intake segment space, and then the flow evenly through the first section up to the level Packing absorption section. Packing on the surface of the gas phase and the liquid ammonia gas or sulfuric Reclaimed water chemical reactions, the reaction of NH3-OH, (NH4) 2SO4, and flows into the lower part of the sump. Not fully absorbed by ammonia gas continue to rise into the first-stage spray section. Absorbed in the spray liquid from the segment of uniform high-speed spray nozzle, the formation of numerous small droplets, contact with mixed gas, chemical reactions continue to occur, and then rise to the secondary Packing ammonia segment, the first segment shower level similar absorption process. The second stage of the first stage nozzle of different density, different pressure liquid jet, absorb acid gas concentration range different. In the process of spray segment and Packing segment it is in contact with two heat and mass transfer process. By controlling the flow rate and residence time of the tower to ensure full and stability of this process. The uppermost tower segment is defogging, the gas absorbing liquid droplet sandwiched herein is cleared down through the clean treated air from the upper end of the exhaust purification tower into the atmosphere.

After water, sulfuric acid or NH3-OH absorption, (NH4) 2SO4, can be used as agricultural fertilizer or boiler desulfurization.

2 Features:

(1) purification rate

SST series purification tower using two reverse spray, Packing large specific surface area, determined by the experimental study of the gas-liquid ratio to ensure stable performance of the ammonia absorption efficiency can reach 85% to 95%.

Low (2) Equipment resistance

Ensuring sufficient gas-liquid contact area basis, SST series absorber selection of aerodynamic characteristics of the best varieties Packing and structure, so that the device resistance at rated air flow does not exceed 40 mm water column, is the lowest resistance to various Packing absorber a. This is equipped with corrosion-resistant low-pressure ventilation is extremely beneficial.

(3) small footprint

SST series purification tower to tower, absorption tank, circulation pump, absorbing liquid pipeline system combined into a complete set of equipment, compact structure, easy on-site installation and operation and management.
