Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization dust collectors, in particular to a desulfurization dust collector for a biomass boiler. Background Art

[0002] The desulfurization dust collector for biomass boiler is a device specially designed to treat flue gas and dust generated by the combustion of biomass fuel, aiming to reduce the sulfur dioxide content in the flue gas and effectively remove smoke particles;

[0003] Through high-speed rotation and diffusion, enhanced turbulent mass transfer is formed with the absorption slurry, so that the gas and liquid form an emulsion layer, thereby achieving an efficient desulfurization effect. At the same time, the dust removal part uses the mechanism of cyclone centrifugal separation and direct current centrifugal dehydration, combined with impact foam condensation and chemical reaction, to effectively remove dust particles in the flue gas, such as a desulfurization dust collector for a biomass boiler disclosed in the publication number CN216909664U. When in use, the application can drive the scraper to move along the height of the processing chamber through the driving component, so that the solid impurities on the inner wall of the processing chamber are scraped off by the scraper, and the scraped solid impurities can be cleaned up from the sewage pipe at the bottom of the processing chamber. First, the scraper in the application is driven by a threaded rod to achieve lifting in the processing tank. However, since the scraper is not provided with a structure to limit axial movement, when the threaded rod rotates in the connecting block of the scraper, it will drive the scraper to rotate together, thereby failing to achieve the lifting function of the scraper. Secondly, after a certain period of use, the outer side of the scraper and the processing tank in the application will cause the inner wall of the processing tank or the outer side of the scraper to wear, so that there is a gap between the outer side of the scraper and the inner wall of the processing tank, which leads to a decrease in the cleaning quality of the attachments on the inner wall of the processing tank.
