Problems solved by technology
[0004] At present, the domestic DMF absorption tower technology is relatively mature, but it can only recover DMF in the waste gas of the copper clad laminate industry, because acetone cannot be recovered, resulting in neither economic benefits nor environmental protection requirements.
As a result, the process cannot be promoted in the copper clad laminate industry

Description
technical field [0001] The invention relates to a recovery device and a method for recovering acetone waste gas by utilizing the recovery device. Background technique [0002] At present, the production of copper clad laminates is produced by wet method, and the glue contains 30%~40% organic solvents. During the dipping and drying process of the base material in the gluing machine, these solvents volatilize into the air, causing great pollution to the environment. The waste gas containing a large amount of organic solvents is usually discharged directly or sent to the waste gas incinerator to burn it. In response to environmental protection requirements and economic benefits, there are very few direct emissions, and most copper clad laminate factories use incineration to treat these waste gases. [0003] At this stage, the regenerative thermal incinerator is used, and its English name is "Regenerative Thermal Oxidizer", or "RTO" for short. Although RTO can oxidize the sol...
