Graphite electrode production flue gas emission filtering device

Abstract

The utility model provides a graphite electrode production flue gas emission filtering device which comprises a box body, a water filtering mechanism is arranged in the box body, the water filtering mechanism comprises a baffle, an end cover, a square hole, a U-shaped pipe, a filtering plate, a water spraying pipe, a water spraying head and a water tank which are arranged in the box body, and a transverse moving mechanism is arranged on the left side of the box body. The filtering device for the graphite electrode production flue gas emission not only can meet the basic requirement for flue gas filtering treatment, but also can perform preliminary washing and filtering on smoke dust through the water filtering mechanism to remove a large amount of impurities in the flue gas, and then performs secondary filtering on the flue gas through the filtering plate to remove a small amount of residual impurities in the flue gas, so that the quality of the flue gas is improved, and the service life of the flue gas is prolonged. Therefore, the filter plate cannot be blocked due to interception of a large amount of impurities in a short time while sufficient filtration and impurity removal of the flue gas are guaranteed, and the flue gas does not need to be continuously and effectively filtered, so that the cleaning frequency of the filter plate is reduced, and the influence on the flue gas filtering efficiency is reduced.

Description

Technical Field

[0001] The utility model belongs to the technical field of filtering equipment for smoke emission from graphite electrode production, in particular to a filtering device for smoke emission from graphite electrode production. Background Art

[0002] Graphite electrodes are an important industrial material, mainly used in electric arc furnace steelmaking and other industrial applications that require high-temperature conductivity. They are made of petroleum coke and asphalt coke as aggregates, coal tar as a binder, and are made into high-temperature resistant graphite conductive materials through a series of complex production processes. The production process of graphite electrodes does produce flue gas containing certain pollutants. In order to reduce environmental pollution and ensure the environmental friendliness of the production process, advanced flue gas purification and filtration devices are usually used.

[0003] In the existing filtering device for flue gas emissions from graphite electrode production, during use, the device often directly filters the generated flue gas through the filtering structure. The filtering structure will directly filter all impurities in the flue gas, so that the filtering structure will filter and retain a large amount of impurities in a short period of time, thereby causing the filter holes of the filtering structure to be blocked, making it impossible for the filtering structure to continue to effectively filter the flue gas, so that the user needs to clean the filtering structure at short intervals, which is not only very troublesome, time-consuming and labor-intensive, but also affects the overall efficiency of filtering the flue gas.

While ensuring that the flue gas is fully filtered and impurities removed, the filter plate will not be blocked in a short period of time due to the interception of a large amount of impurities, and there is no need to continue to effectively filter the flue gas, thereby reducing the cleaning frequency of the filter plate and reducing the impact on the efficiency of flue gas filtering.
