The working principle of the Venturi scrubber: Waste gas is drawn into the Venturi tube’s contraction section by the fan’s suction force. The narrowed throat tube increases the gas flow rate, allowing the gas to mix with the liquid in the abdominal area. The atomizing nozzles installed at the air inlet further enhance the contact and mixing of the gas and liquid, collecting larger pollutants in the gas, which then fall directly to the bottom of the scrubber due to gravity. Fine pollutants, on the other hand, continue to rise under the fan’s suction force and enter the packing layer. The packing increases the contact area between the waste gas and the absorption liquid, providing sufficient time for thorough chemical reactions. After passing through two layers of packing, the gas rises to the storage layer, where water mist and droplets in the gas condense and fall into the scrubber body. The gas after storage is discharged through the exhaust outlet in compliance with standards or sent to the subsequent process for further treatment. The equipment adopts a modular design, allowing for direct replacement of the packing, which saves maintenance costs in the long run.
