Falling film absorption tower is a gas-liquid mass transfer equipment widely used in waste gas treatment, chemical production and other fields. The equipment is made of corrosion-resistant materials such as PP plastic and graphite, which can withstand high temperature, low temperature and corrosive medium environments without polluting the treated medium.

Measurement steps for falling film absorption tower:

1. Connect the system and introduce gas: Connect the external exhaust gas pipeline to the absorption tower body through the intake pipe, ensuring that the exhaust gas can evenly enter the liquid inside the tower through the annular pipe network. This step ensures the effective introduction and initial distribution of the gas to be treated.

2. Start the stirring device: Turn on the stirring motor to drive the stirring shaft and blades to rotate, promote full contact and mixing between the gas-liquid phases, and enhance mass transfer efficiency. The stirring effect helps to break down interfacial resistance and improve absorption efficiency.

3. Adjust operating parameters: Select appropriate process dimensions such as packing type, tower diameter, and packing layer height based on the characteristics of the system and separation requirements, and calculate the corresponding tower height and pressure drop. At the same time, it is necessary to consider the influence of spray density on the formation of liquid film and optimize the uniformity of liquid distribution to maintain a stable falling film state.

4. Monitoring operational data: Continuously monitor key parameters (such as pressure difference, temperature changes, concentration gradients, etc.) during operation to evaluate mass transfer efficiency and equipment performance. If necessary, adjust the gas flow rate or liquid circulation rate to achieve the operating conditions.

5. Sampling analysis: Regularly collect gas and liquid phase samples from different locations for component testing to verify whether the absorption effect meets the expected target. Quantify the purification capacity of equipment by comparing the differences in pollutant content at the import and export points.

Precautions for using falling film absorption tower:

1. Installation foundation requirements: The equipment should be installed on a concrete foundation that is at least 150 millimeters above the ground, especially for components such as water pumps and fans, which need to be stable and reliable. This helps to reduce vibration transmission and ensure long-term stable operation.

2. Transportation protection measures: Avoid dragging the ground during handling or lifting, pay attention to speed control to prevent collision damage to the body and its internal components. For equipment that is packaged and transported in sections, it should be assembled and debugged on-site by professional technicians.

3. Operation specifications: When tightening bolts, apply even force; When opening and closing the inlet and outlet valves, it should be done slowly to prevent equipment damage caused by severe material impact. In addition, the start-up or shutdown phase should also follow the principle of progressive operation.

4. Maintenance and cleaning management: Regularly clean the accumulated dirt inside the equipment. If blockages or other abnormal situations are found, the machine should be stopped and cleaned in a timely manner before resuming use. Maintaining good hygiene conditions is beneficial for extending equipment lifespan and maintaining efficient performance.

5. Preventing liquid flooding: Special attention should be paid to the rationality of the liquid distributor during design to ensure that the falling film evenly covers the surface of the packing and avoid local excessive thickness causing liquid flooding problems. In actual operation, abnormal fluid accumulation can be determined by observing changes in pressure drop.

6. Material compatibility considerations: Components made of corrosion-resistant materials (such as PP material suitable for acidic environments) are selected for different types of media to improve the system's chemical resistance and safety.
