化学空气洗涤器通过在水中吸收，随后进行化学转化并去除最终产物，来降低流出的通风空气中的水溶性成分（如氨）的浓度。建立了逆流空气洗涤塔的机理模型。氨，硫化氢，一氧化二氮和甲烷的质量平衡，以及水的质量平衡和热量平衡。该模型进行了验证，从传统的育肥猪舍设施的实验数据。通过模拟研究了进水特性、设计参数和控制手柄对去除效率、温度分布和水蒸发速率的影响。该模型能够描述逆流化学空气洗涤器的行为。
Chemical air scrubbers reduce the concentration of water-soluble components such as ammonia from the outgoing ventilation air through absorption in water, followed by chemical conversions and removal of the end products. A mechanistic model for a countercurrent air scrubber was set up. Mass balances for ammonia, hydrogen sulfide, nitrous oxide, and methane were implemented, as well as the water mass balance and heat balances. The model was validated against experimental data from a conventional fattening pig housing facility. The effect of influent characteristics, design parameters, and control handles on the removal efficiency, the temperature profile, and the water evaporation rate were investigated through simulation. The model was able to describe the behavior of a countercurrent chemical air scrubber.
