[0002] Chinese patent announcement number CN205856902U discloses a leather dry gas recovery and reuse device, including a drying box and a spray tower. A number of air outlet branches are evenly distributed on the top of the drying box, and the air outlet branches are connected to the air outlet main pipe. The air outlet main pipe is connected to the main pipeline via an exhaust fan A, and the main pipeline is connected to the air intake branch via an exhaust fan B. The air intake branch is connected to the spray tower. A spray head for spraying absorption liquid is provided on the upper part of the spray tower, and a drain port for recovering the internal liquid is provided on the lower part of the spray tower.
[0003] The utility model utilizes the full contact between the absorption liquid and the gas inside the spray tower to convert the gas from the gas phase into the liquid phase and then recycle it. Since the working principle of the spray tower is: the absorption liquid is sprayed on the packing layer, the packing layer is used to increase the gas-liquid contact area, usually composed of plastic or metal blocks of various shapes. If the spray tower is not large enough, the gas will be limited in the spray tower. The residence time, resulting in insufficient absorption, if a larger spray tower is used, will lead to increased production costs. Utility Model Content
