Description

Technical Field

[0001] The utility model relates to the technical field of graphitization furnace waste gas treatment, in particular to a spray atomization dust removal device for graphitization furnace waste gas. Background Art

[0002] The exhaust gas from the graphitization furnace contains a large amount of harmful substances, such as hydrocarbons, benzene series, sulfides, etc. These substances cause serious pollution to the atmospheric environment. It is usually necessary to decompose the harmful substances in the exhaust gas. Since sulfides and hydrocarbons can cause acid rain and greenhouse effect, treating the exhaust gas can reduce these adverse effects, thereby reducing the impact of the exhaust gas on the health of the surrounding people.

[0003] Chinese Patent Publication No. CN215692797U discloses a spray atomization dust removal device for graphitization furnace exhaust. The device sequentially transports the exhaust gas through a second dust removal chamber's aggregation and oxidation device and a wet dust removal device to the second dust removal chamber's outlet for discharge into the surrounding environment. This device effectively removes fine particulate matter from the exhaust gas while minimizing waste gas treatment costs.

[0004] However, in the specific use of the existing spray atomization dust removal device for graphitization furnace exhaust, as can be seen in the above scheme, there are still some problems: the graphitization furnace generally generates a large amount of exhaust gas during the production process, and usually a spray atomization dust removal device is required to wet the particles in the dust so that they no longer float. However, the dust will be raised again after slowly drying, which reduces the dust reduction effect, increases the cleaning cost, and causes secondary pollution. Utility Model Content
