Novel flue gas desulfurization equipment

Abstract

The invention relates to a novel flue gas desulfurization device which comprises a first-level vortexing whirlwind device, flue gas baffling plates, flow guiding columns, spiral nozzles, a rotational flow dehydrating device, a water baffle and a water-containing disc, wherein the first-level vortexing whirlwind device is arranged at the side of a flue gas inlet; the flue gas baffling plates are parallelly arranged in a bath tower; the flow guiding columns are transversely arranged among the flue gas baffling plates and are arranged transversely and vertically; the spiral nozzles are arranged among the flue gas baffling plates; the built-in rotational flow dehydrating device and the water baffle are placed at the side of a flue gas outlet; the water-containing disc is placed on the lower part of the novel flue gas desulfurization device and is provided with an aerating device; the vortexing whirlwind device and the plurality of flue gas baffling plates are arranged at the side of the flue gas inlet; the flow guiding columns are arranged in the middles of the smoking baffling plates; flue gas flows a unique spraying region formed by the spiral nozzles arranged on key positions so as to fully contact and react with a circulating desulfurization liquid; and the water-containing disc at the lower part of a scrubbing tower can contain abundant water, guarantees that a desulfurizer and desulfurization products are sufficiently mixed, and enables part of the unstable desulfurization products to be furthered oxidized by aeration.

Description

technical field [0001] The invention relates to a novel flue gas desulfurization equipment, in particular to a flue gas water washing equipment, which belongs to the field of desulfurization equipment water washing towers. Background technique [0002] Magnesium oxide wet desulfurization technology is a desulfurization process second only to the calcium method in maturity. Magnesium oxide desulfurization process has a lot of application performances all over the world. At present, there have been application performances in some areas of my country, but the quantity, There is still a lot of room for development in terms of scale and technical level. The reserves of magnesium oxide in my country are very considerable. Therefore, magnesium oxide can be used as a desulfurizer in the desulfurization system of the power plant. [0003] The commonly used desulfurization method is calcium desulfurization. Calcium hydroxide is not as thorough as magnesium hydroxide, and its chemica...

Problems solved by technology

Chinese patent CN101966416A provides a water washing tower for desulfurization equipment, which enables heat exchange between flue gas and desulfurization circulating water, chemical desulfurization and further oxidation of desulfurization products. The unique spray area formed by the spiral nozzles installed at each pipe fitting, but the flue gas cannot fully contact the circulating water, and the efficiency is low. Therefore, it is particularly important to develop equipment that fully contacts the flue gas and circulating water

[0004] This invention is to overcome the shortcomings of insufficient contact between flue gas and circulating water, and provide a new type of flue gas desulfurization equipment
