Description

Technical Field

[0001] The invention relates to the technical field of smoke purification, in particular to an environmentally friendly smoke purification device. Background Art

[0002] In industrial production, welding, chemical reactions and other processes will produce smoke containing harmful substances such as acetaldehyde, rosin acid, isocyanate, nitrogen oxides, sulfides, hydrocarbons, etc. For the treatment of these fumes, large factories usually collect the flue gas first, and then centrally use the purification device for environmental protection treatment to ensure that the treated flue gas meets the emission standards. However, there are some problems with the existing smoke purification device: in the process of treating the smoke, the smoke needs to be in contact with the water mist sprayed by the spray mechanism in advance to filter the particulate dust in the smoke. However, during the spraying process, the air flow rate at the position where the high-pressure water mist flows is too fast, and the smoke mass is light and is easily driven by the airflow, resulting in the smoke being unable to fully contact with the water mist, thereby affecting the quality and efficiency of the initial treatment of the smoke. In addition, after the smoke is sprayed, it directly enters the interior of the filter mechanism, which is easy to soak the filter material. After soaking, the filter material is prone to deformation, affecting the adsorption effect of the smoke and affecting the service life. A large amount of odor will remain in the filtered gas. When the gas emission reaches a certain level, these odors will also pollute the environment. Therefore, it is necessary to design a kind of environmental protection smoke purification device.

After being filtered, the smoke can enter the deodorization box. The ions emitted by the current flowing through the metal filter will electrolyze the smoke.
