[0002] Packed towers are commonly used gas-liquid mass transfer devices in chemical production. During gas-liquid mass transfer operations, the liquid typically enters the tower directly from the inlet at the top. Uneven liquid distribution can lead to insufficient gas-liquid contact, affecting mass transfer efficiency. Therefore, a packed tower with adjustable liquid distribution is needed.

[0003] In the prior art, utility model patent with patent number CN201220709918.X discloses a liquid distributor for a packed tower. It consists of an annular plate fixed to the inner wall of the packed tower. Below the central channel of the annular plate, a cylindrical distribution trough is installed to collect and allow liquid to flow down from the annular plate. The bottom of the distribution trough is a liquid redistribution plate with liquid holes. A shallow ring is attached downwards to the edge of the central channel of the annular plate. The inner diameter of the cylindrical distribution trough is larger than the inner diameter of the shallow ring. The cylindrical distribution trough is fixed to the inner wall of the packed tower by at least three vertically arranged guide ribs connected to its outer circumference.

Simultaneously, the liquid flows and mixes inside the installation pipe 1 along the spiral path of the screw 6, increasing the speed of water molecule movement within the liquid and preventing impurities in the liquid from accumulating and causing blockage in the liquid distribution device 5. When it is necessary to replace the distribution pipe 502 with a different flow rate, the second motor 408 can be started. The rotation of the second motor 408 drives the drive gear 409 to...

Then, the first motor 105 is started, driving the lead screw shaft 104 to rotate. During the rotation of the lead screw shaft 104, the threaded sleeve 401 in the automatic opening and closing device 4 moves laterally to the working area 102.
