The adsorption tower adopts a double-tower alternating work mode, one tower for adsorption while the other tower for regeneration treatment.

[0070] Regeneration and recovery: when the adsorbent in the adsorption tower reaches saturation, the regeneration unit starts. The electric heater heats the adsorbent, desorbs the adsorbed oil and gas and sends it back to the recovery process. After the regeneration process is completed, the adsorption tower is put back into operation.

[0071] Intelligent control: The intelligent control unit calculates the optimal recovery strategy based on real-time monitoring of environmental parameters and preset algorithms. The actuator controller adjusts the working state of the recovery processing unit according to the instructions of the central processor, realizing precise control of the oil gas recovery process.

[0072] Safety protection: The safety protection unit monitors key parameters such as flow and pressure in real time. When an abnormal situation is detected, the emergency shut-off valve automatically cuts off the connection of related equipment to ensure system safety. At the same time, the emergency relief unit safely releases accumulated oil gas to a safe area when necessary.

[0073] Visual monitoring: The visual monitoring unit monitors the running state of the equipment and the on-site environment in real time through high-definition cameras and infrared imagers. The wireless communication module transmits data to the cloud server, realizing remote monitoring and data analysis. Operators can remotely access these data through mobile phones or computers and make adjustments and optimizations as needed.
