AI Technical Summary
In existing multi-layer spray towers, formaldehyde gas needs to pass through multiple layers of packing material in sequence. As a result, the formaldehyde in the gas that the upper packing material comes into contact with during use has already been absorbed by the lower packing material, resulting in low purification efficiency and increased burden on the fan.
A multi-layer high-efficiency spray-type formaldehyde absorption tower is designed, which adopts a pressure drop reduction mechanism, including a combination of movable pipe and packing plate. By switching the position of the movable pipe and the packing plate, the airflow path is optimized, ineffective absorption paths are reduced, and purification efficiency is improved.
By optimizing the airflow path, the burden on the fan is reduced, the formaldehyde absorption efficiency is improved, and the operating pressure drop of the equipment is reduced.
