强化混合的流化床烟气脱硫装置
摘要：
本发明属于工业废气净化环保及化工领域，特别涉及一种强化混合的流化床烟气脱硫装置，其特征是文丘里管喉管内安装固定挡板，固定挡板下方设有调节挡板，调节挡板与固定挡板相铰连；脱硫塔筒体下部设有收缩机构。本发明的调节挡板向进气口一侧转动后，更大部分烟气在进气口对面一侧烟道内流动，流动偏转得到强化，这部分气流在向上流动中受到收缩机构的阻碍，产生了较大的横向速度，形成强烈的脱硫塔内循环，固相的停留时间增加，强化了气液固三相的混合，有利于提高钙利用率和脱硫效率。
摘要（英）：

The invention belongs to the field of industrial waste gas purification environmental protection and chemical engineering, in particular an enhanced mixing flue gas desulfurization device of a fluidized bed. The enhanced mixing flue gas desulfurization device is characterized in that a fixing baffle plate is mounted in a throat tube of a venture tube; an adjusting baffle plate is arranged below the fixing baffle plate; the adjusting baffle plate is articulated with the fixing baffle plate; and the lower part of a desulfurization tower cylinder body is provided with a contractile mechanism. When the adjusting baffle plate rotates towards one side of a gas inlet, a large amount of flue gas flows in a flue opposite to the gas inlet, so that the flow deflection is enhanced, the gas current ofthe flue gas is obstructed by the contractile mechanism during upward flow to generate a larger lateral velocity and form a strong circulation in the desulfurization tower, so that the residence timeof a solid phase is increased, the mixing of phases of gas, liquid and solid is enhanced, and the calcium utilization and the desulfurization efficiency are beneficial to improve.
