Problems solved by technology
Existing production equipment and devices absorb the flue gas and discharge it directly, causing a lot of environmental pollution. At the same time, because the coal tar in the flue gas is adsorbed and bonded to the fan blades and the casing of the fan, the life of the fan is shortened, and Shorter maintenance intervals

Embodiment Construction
[0012] A filter device for flue gas emission from graphite electrode production, such as figure 2 As shown, the filter device is a pull-out frame device installed at the front end of the fan impeller 6 of the graphite electrode production flue gas discharge suction duct 5 . like figure 1 As shown, the filter device of the present invention includes a frame 1 , a filter screen 2 and a filter element 3 , and a handle 4 is provided outside the frame 1 . The filter screen 2 is arranged at both ends of the frame 1, and the filter screen 2 is flexibly connected with the frame 1. The filter element 3 is installed in the center surrounded by the frame 1 and the filter screen 2 . Frame 1, filter screen 2 and handle 4 are made of metal materials. The mesh diameter of the filter screen 2 is a square hole of 15-20mm or 15-20mm×15-20mm. The filter element 3 is granular activated carbon or graphite electrode material.
[0013] When working, open the filter screen 2 at one end of the f...

The invention discloses a filtration device for flue gas discharged in production of graphite electrodes. The filtration device comprises a framework, filter screens and a filter element, wherein a pull handle is arranged outside the framework, the filter screens are arranged at two ends of the framework and are movably connected with the framework, the diameters of meshes of the filter screens are 15-20 mm, or the meshes of the filter screens are square holes of 15-20mm*15-20mm, the framework, the filter screens and the pull handle are made of metal materials, the filter element is arranged at the center of a space enclosed by the framework and filter screens, and the filter element is made of a granular active carbon or graphite electrode material. The filtration device is arranged at the front end of a fan impeller of an air suction pipeline for discharging flue gas generated in production of the graphite electrodes. With the filtration device, the service life of a fan is prolonged; the maintenance period of the fan is greatly prolonged; without usage of the filtration device, the cleaning and maintenance period of the fan is 6 to 7 days; after the filtration device is mounted, the cleaning and maintenance period of the fan is 5 to 6 months, so environmental pollution is reduced, and working environment is improved.
Description
technical field [0001] The invention relates to a flue gas discharge device, in particular to a filter device for flue gas discharge in the production of graphite electrodes. Background technique [0002] At present, a large amount of flue gas is produced during the kneading and cooling process of graphite electrodes, and the flue gas contains more coal tar, sulfur, phosphorus and other components. Existing production equipment and devices absorb the flue gas and discharge it directly, causing a lot of environmental pollution. At the same time, because the coal tar in the flue gas is adsorbed and bonded to the fan blades and the casing of the fan, the life of the fan is shortened, and The maintenance period is short. Contents of the invention [0003] The purpose of the present invention is to install a filter device on the exhaust duct produced by graphite electrodes to filter out harmful components such as coal tar in the flue gas, so as to protect the fan from erosion ...
