[0002] The tower is filled with packing of appropriate height to increase the contact surface between the two fluids. The packed tower uses the liquid to flow from top to bottom along the packing surface. The gas and liquid are in countercurrent or cocurrent, and interact with each other in close contact. It has a simple structure and is easy to maintain. It is widely used in gas absorption, distillation, extraction and other operations.

[0003] Based on the above, the inventors found that the following problems exist: when the current packed tower is in use, it usually needs to be in full contact with the exhaust gas to better treat the exhaust gas, but in actual use, the packing and the exhaust gas cannot be in better contact, resulting in insufficient reaction and poor effect. In addition, when the exhaust gas is filtered through the filter during use, impurities remain in the filter and are not cleaned in time or cause blockage, affecting the filtering effect.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a highly enclosed waste gas absorption packed tower is provided, in order to achieve a purpose with greater practical value. Utility Model Content
