Description

Technical Field

[0001] The utility model relates to an absorption tower in the field of metallurgical and chemical equipment. Background Art

[0002] With the development of production, metallurgical and chemical packed towers, that is, packed towers used to distill liquids by absorbing gases, are daily used in chemical plant production. With the continuous attention and investment in metallurgical and chemical packed towers, metallurgical and chemical packed towers have been well improved to a certain extent, which can facilitate distillation in packed towers. However, the existing metallurgical and chemical packed towers still have certain shortcomings. In the actual production application process, there is insufficient fusion of packings with waste gas and liquid, and the surface area contact between the packing grooves used to place the packings and the packings is too large, which brings certain impacts in the actual use process. For this reason, we propose an improved packed absorption tower. The packing grooves placed in the absorption tower are made of a circular frame, which can minimize the contact area with the packing and can effectively support the packing. Utility Model Content

[0005] When the utility model is working, the exhaust gas can be introduced into the lower air inlet part, and the introduced exhaust gas passes through the middle filler absorption part in turn and then flows out from the top air outlet part. The demister of the top air outlet part can effectively perform defogger to avoid generating a large amount of mist. During use, the upper absorption part and the lower absorption part of the middle filler absorption part respectively realize the adsorption of harmful substances in the exhaust gas through the corresponding several layers of split filler layers. During adsorption, the spray pipe continuously and evenly sprays, and the gas-liquid two-phase close contact is carried out on the surface of the filler placed in the filler groove to more fully transfer the harmful substances in the exhaust gas. Since the filler groove adopts a frame structure, the contact between the filler and the exhaust gas can be guaranteed to the maximum extent. At the same time, the filler placement part is used to place filler, and filler can also be placed between the upper fan-shaped support sheet or the lower fan-shaped support sheet and the central circular frame, so as to ensure that the filler surface of the entire split filler layer is in full contact with the exhaust gas and liquid.

[0006] The beneficial effect of the utility model is that it provides a packed absorption tower; the utility model has a simple structure, and through the multi-layered packing grooves and hollow structures, close contact between gas and liquid phases on the packing surface is achieved to achieve more sufficient mass transfer of waste gas, effectively improve work efficiency and reduce costs.
