Description

Technical Field

[0001] The utility model belongs to the technical field of chemical engineering, and particularly relates to a mechanical demisting component. Background Art

[0002] At present, the wet desulfurization of sulfur-containing flue gas by a wet desulfurization system using the limestone-gypsum method is widely used in domestic coal-fired thermal power units. It has the advantages of fast desulfurization reaction, high efficiency, and high utilization rate of desulfurization additives. However, the flue gas after wet desulfurization has high water content, low temperature, is easy to condense, and also contains strongly corrosive substances such as fluorides and chlorides, which are likely to form low-temperature high-humidity dilute acid corrosion on the downstream equipment of the flue gas, that is, it has strong corrosiveness to downstream equipment such as chimneys. In order to reduce the corrosion degree of the flue gas after desulfurization on the equipment, generally a demister and a heater are set on the discharge path after flue gas desulfurization. The demister is used to remove the droplets in the flue gas. These droplets not only contain moisture but also corrosive substances and are the main corrosion sources of the equipment. The heater is used to increase the temperature of the flue gas, reduce the condensation amount of the droplets, and prevent the occurrence of corrosion reactions. A mechanical demisting component is required.

[0003] At present, the Chinese patent with the publication number CN211635849U discloses a flat demister, including a fixed curved plate and a connecting piece. The right end of the fixed curved plate is installed with a connecting piece. A connecting plate is arranged on the outer wall of the upper end of the fixed curved plate. A fixed shaft is arranged inside the connecting plate. An adjusting absorption device is arranged on the outer wall of the upper end of the fixed curved plate on the front side of the fixed curved plate.
