Abstract

The invention relates to a demister blade unit for a demister. The demister blade unit comprises a plurality of blades arranged in parallel at intervals, wherein each blade comprises a blade body, a net-shaped structural layer and cones, the cones are arranged on the outer surface of the blade body at intervals along the blade body, the vertexes of the cones are arranged in the gravity settling direction of liquid drops, and the net-shaped structural layer is arranged tightly on the outer surface of the blade body outside the cones. The demister blade unit is provided with the cones and the net-shaped structural layers, the blade structure of a plate type demister is improved, the problem of re-entrainment of flue gas by the demister can be solved effectively, the demisting efficiency of the plate type demister is improved, efficient demisting can be realized, and the demister has small resistance and low system investment cost, so that the demister blade unit for the demister can be applied to separation of the flue gas and the liquid drops in a wet flue gas desulfurization system.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, in particular to a mist eliminator blade for a mist eliminator, a high-efficiency mist eliminator and its application. Background technique [0002] my country is the largest coal producing country in the world and also a big coal consuming country. It needs a large amount of coal for power generation every year, and the atmospheric pollutants produced by coal have a serious impact on the environment. Wet flue gas desulfurization technology is one of the most widely used pollution gas control technologies in coal-fired power plants, but the flue gas in the desulfurization gas carries a large number of slurry droplets, so the desulfurization tower mist eliminator is the most widely used in the whole wet desulfurization system. An important piece of equipment, traditional plate mist eliminators can hardly capture smaller mist droplets, especially in the case of high-speed flue gas ...
