Description

Technical Field

[0001] The utility model belongs to the technical field of flue gas and waste gas purification and treatment, in particular to a high-temperature flue gas wet desulfurization and denitrification dust collector. Background Art

[0002] With increasingly stringent environmental regulations and the continuous improvement of industrial emission standards, high-temperature flue gas wet desulfurization, denitrification and dust removal technology has become a key means for large industrial facilities such as coal-fired power plants and chemical plants to reduce atmospheric pollutant emissions. This technology sprays desulfurization and denitrification agents into high-temperature flue gas and achieves efficient removal of sulfur oxides and nitrogen oxides in a wet environment. At the same time, a dust removal device is used to capture particulate matter in the flue gas, and finally a post-reaction solution containing by-products such as ammonium sulfate is generated. In this process, the filter plate is the core component for separating solid by-products and post-reaction solutions, and its performance is directly related to the operating efficiency of the entire desulfurization, denitrification and dust removal system and the quality of by-product recovery.

[0003] However, when the existing high-temperature flue gas wet desulfurization and denitrification dust collector is in use, it is not convenient to clean the filter plate for separating the post-reaction solution of ammonium sulfate. Impurities on the filter holes will accumulate over time, causing the filter plate to be blocked, thereby reducing the filtration efficiency and even damaging the filter plate, resulting in shutdown.

When the side of the half gear without teeth turns to the side of the rack, the power storage of the spring 1 is completed, and the oscillating block will fall rapidly with gravity and the elastic force of the spring 1 and hit the filter plate. The slide bar 1 and the rack are also reset to prepare for the next power storage. When the teeth of the half gear contact the rack again, this process will be repeated, so that the oscillating block will continuously hit the filter plate, generating continuous oscillation on the filter plate, so that the small impurities accumulated in the filter holes are loosened and fall off, thereby keeping the filter holes unblocked and avoiding the blockage of the filter plate, thereby reducing the filtration efficiency, or even damaging the filter plate, resulting in shutdown.
