As far as activated carbon adsorption is concerned, the current regeneration technologies include thermal regeneration, chemical agent regeneration, biological regeneration, electrochemical regeneration, etc., but in the field of environmental development, all thermal regeneration methods must be condensed before entering the separator. According to relevant information, this regeneration cooling device is widely used in the petrochemical and pharmaceutical fields, and is mostly used to recover valuable components. The purpose of our transformation this time is to reduce environmental pressure, reduce environmental pollution, increase the service life of the adsorbent, and ensure the smooth operation of the subsequent system. The refined de-oiling and naphthalene removal system uses activated carbon for refined de-oiling and naphthalene removal. After adsorption saturation, steam regeneration is required to be able to have adsorption performance again.

[0003] However, during the regeneration process, the existing regeneration steam is not cooled and directly enters the atmospheric pressure collection tank. The tank body is heated and finally the regeneration steam is discharged along the high-point vent pipe. The steam carries out impurities such as tar and naphthalene. After being cooled by air, droplets are formed, which pollute the surrounding equipment, pipelines, and the ground, and the environment is filled with a pungent smell. Utility Model Content
