Problems solved by technology
However, when the currently used filter device is filtered for a long time, impurities are easily attached to the filter purification layer, resulting in a decrease in the filtration effect. In severe cases, the filter purification chamber will be blocked and damaged, which directly affects the treatment process of desulfurization wastewater.

Abstract
The invention discloses an anti-blocking filter device for power plant desulfurization wastewater treatment. The anti-blocking filtering device comprises a filtering box body, a filtering anti-blocking cavity and a filtering purification cavity are sequentially formed in the filtering box body from top to bottom, a filtering anti-blocking layer is arranged on the lower portion of the filtering anti-blocking cavity, and a discharging window is arranged on the side wall, located at one end of the filtering anti-blocking layer, of the filtering box body. An anti-blocking cleaning assembly is arranged on the upper surface of the filtering anti-blocking layer at the end away from the discharging window, and a filtering purification layer is arranged in the filtering purification cavity locatedbelow the filtering anti-blocking layer. The filtering anti-blocking layer provided with the anti-blocking cleaning assembly is arranged above the filtering purification layer, under the condition oflong-time filtering, impurities attached to the filtering purification layer are effectively reduced, the filtering effect is guaranteed, the situation that the filtering purification cavity is blocked and damaged is reduced, and through the arrangement of the replaceable filtering purification layer and matching with a replacement window, the filtering purification layer is convenient to replace,and the desulfurizing wastewater treatment process is smoothly carried out.
Description
technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to an anti-blocking filter device for treating desulfurization wastewater in a power plant. Background technique [0002] Power plants mainly rely on coal as raw material for power generation. There will be a large amount of sulfur dioxide in the flue gas generated during the operation of the power plant. The current mainstream technology for treating sulfur dioxide pollution is wet limestone desulfurization, which uses limestone slurry to neutralize sulfur dioxide. Power plant desulfurization wastewater is the wastewater discharged from the wet limestone desulfurization process of the power plant. The wastewater is characterized by high concentration of suspended solids, high chloride radicals, high salt content, and high concentration of heavy metals, which is extremely polluting to the environment. Pretreatment is carried out to ensure that the desulfurization reacti...
