Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization devices, in particular to a desulfurization device for deep desulfurization of micro-interface fillers. Background Technique

[0002] Currently, the mainstream technology for flue gas desulfurization widely relies on the application of desulfurization towers. The tower is carefully designed with a spray layer inside, and its core components are a series of high-efficiency nozzles. These nozzles precisely spray desulfurization liquid to form a fine water mist. When sulfur-containing flue gas passes through the desulfurization tower, this water mist fully contacts the flue gas, effectively capturing and absorbing the sulfide components in it, and realizing the purification treatment of the flue gas. This technology not only improves the desulfurization efficiency but also ensures compliance with environmental emissions, and is one of the important flue gas treatment means in the current environmental protection field.

[0003] Most existing flue gas desulfurization devices use a micro-interface generator for desulfurization operations. The micro-interface generator includes an air inlet pipe and a liquid inlet pipe. The working principle of the micro-interface generator is: the liquid tangentially enters the micro-interface generator through the liquid inlet pipe, rotates at a super-high speed and cuts the gas, causing the gas bubbles to break into micro-bubbles at the micron level, thereby increasing the mass transfer area between the liquid phase and the gas phase.

[0004] Existing spray towers have limitations in gas-liquid contact, specifically manifested as insufficient contact, which directly leads to low mass transfer efficiency, and further affects the overall efficiency of the desulfurization reaction. In the face of flue gas with high sulfur content or extreme working conditions, this deficiency is particularly obvious, and it cannot perform deep desulfurization operations, which may cause the desulfurization effect to fail to meet the standards.
