Abstract

The invention discloses a tangent circle spiral spraying wet method smoke sulfur removal device, which comprises an absorbing tower. A tangent circle spiral spraying turbulence absorbing layer, a regular spraying layer and a defogging layer are sequentially arranged in the absorbing tower from bottom to top, the tangent circle spiral spraying turbulence absorbing layer is formed by a plurality ofgroup of ultrasonic atomizing nozzles of a hedging tangent circle arranged along a circular pipeline, and the regular spraying layer is formed by a plurality of mechanical nozzles arranged in an array. A high-efficient atomizing nozzle is arranged on the tangent circle spiral spraying turbulence absorbing layer so as to form a tangent circle spiral spraying turbulence absorbing field, produced atomization particles of 50-400mum rise in a spiral mode, mixing uniformity of reactants are improved, contact time is prolonged, absorbing and reacting speed is quickened, and sulfur removal efficiencyis improved. The tangent circle spiral spraying wet method smoke sulfur removal device can reduce sulfur removal liquid-air rate, greatly reduce number of the atomizing nozzles, reduce volume of a sulfur removal tower, lower sulfur removal cost and energy consumption, and be widely used in a wet method smoke sulfur removal system in industries like electricity, petrifaction, metallurgy and cement.

Description

technical field

[0001] The invention relates to a flue gas desulfurization device, in particular to a tangential spiral jet wet flue gas desulfurization device. Background technique

[0002] SO 2 Pollution is the main problem of air pollution in our country and an important environmental factor that restricts the coordinated and stable development of our economy. With the rapid development of thermal power plants, SO 2 Emissions are increasing. while SO 2 It is one of the main reasons for the increasing acid rain. How to implement desulfurization projects in coal-fired power plants, improve desulfurization process, and improve desulfurization efficiency are the key to effectively curb SO 2 effective means of emission. Lime / limestone-gypsum wet flue gas desulfurization technology is currently the 2 One of the most mature technologies and is widely used. However, there are also problems of low desulfurization efficiency, high energy consumption and high desulfurization...
