[0033] Compared with the prior art, the beneficial effects of this utility model are:

[0034] 1. This VOCs waste gas treatment tower, through the arrangement of rotating components, buffer plates, and treatment components, allows waste gas to enter the tower body through the inlet during operation. The servo motor is activated, and the rotating rod drives the spiral impeller to rotate, changing the flow direction of the waste gas. When encountering the buffer plate, the waste gas remains inside the tower body for an extended period. The gas passes through "W"-shaped activated carbon packing, increasing the contact area between the gas and liquid, thereby changing the flow direction of the waste gas, improving the gas-liquid contact time and mixing effect. This prevents the waste gas from flowing rapidly upwards after entering the tower body, resulting in a shorter residence time inside the tower body, which would affect the gas-liquid contact and mixing effect, thus improving the VOCs waste gas treatment efficiency.

[0035] 2. This VOCs waste gas treatment tower, through the configuration of circulation components, gas sensors, and a PLC controller, monitors the discharged gas according to the monitoring threshold set by the PLC controller during operation. When the discharged gas exceeds the monitoring threshold, the PLC controller controls the B electromagnetic three-way valve to rotate to the delivery pipe A. The A electromagnetic three-way valve opens, connecting to the delivery pipe A, preventing new waste gas from entering. The gas pump is then activated to send the unqualified gas back to the treatment tower body for further treatment. This reduces VOCs waste gas emissions, increases the efficiency of VOCs waste gas treatment, avoids insufficient VOCs waste gas treatment causing environmental pollution, improves the safety of waste gas emissions, and reduces environmental pollution.
