The spray system of desulfurization absorption tower (spray layer glass fiber reinforced plastic mist eliminator backwashing) is the core system of the whole desulfurization unit. The process of removing harmful components such as SO2 from flue gas is mainly completed in this system.
脱硫吸收塔喷淋系统喷淋层采用高级的螺旋状喷嘴，在同等喷雾条件下，对循环泵的压力需求较低。该种喷嘴可使喷出的三重环状液膜气液接触效率高，能达到高效吸收性能和高除尘性能。喷淋层的布置增加了浆液与气体的接触面积和几率，保证吸收塔横截面能被完全布满，使SO2、SO3、HF、HCl等被充分去除。由于在吸收塔内吸收剂浆液通过循环泵反复循环与烟气接触，吸收剂利用率很高。
The spray layer of the desulfurization absorber spray system adopts advanced spiral nozzles. Under the same spray conditions, the pressure demand of the circulating pump is relatively low. This kind of nozzle can make the gas-liquid contact efficiency of the ejected triple annular liquid film high, and can achieve high absorption performance and high dust removal performance. The arrangement of spray layer increases the contact area and probability between slurry and gas, ensures that the cross section of absorption tower can be fully filled, and removes SO2, SO3, HF, HCl and so on. Because the absorbent slurry in the absorber contacts the flue gas repeatedly through the circulating pump, the absorbent utilization rate is very high.
脱硫吸收塔喷淋系统(喷淋层反冲洗)除雾器用于分离烟气携带的液滴，防止冷烟气玷污GGH、烟道等。本工程采用折流板玻璃钢除雾器，是利用液滴与固体表面的相互撞击而将液滴凝聚并捕集。气液通过曲折的挡板，流线多次偏转，液滴则由于惯性而撞在挡板上被捕集。经过净化处理的烟气流经两级卧式除雾器，在此处将烟气携带的浆液微滴除去。从烟气中分离出来的小液滴慢慢凝聚成比较大的液滴，然后沿除雾器叶片的下部往下滑落，直到浆液池。经洗涤和净化的烟气流出吸收塔，最终通过烟气换热器升温后经净烟道排入烟囱。
The spray system of desulfurization absorption tower (backwashing of spray layer) mist eliminator is used to separate droplets carried by flue gas and prevent cold flue gas from polluting GGH, flue, etc. In this project, baffle plate FRP mist eliminator is used to collect and condense droplets by means of the collision between droplets and solid surfaces. Gas and liquid pass through the tortuous baffle, www.zhutiezhamen.net.cnwww.buxiugangwanguan.cnwww.penwuganzaojii.cnwww.gangchensu.cn
www.chenban.net.cnwww.taocichenban.cnstreamlines deflect many times, droplets are trapped on the baffle due to inertia. The purified flue gas passes through a two-stage horizontal demister, where the slurry droplets carried by the flue gas are removed. The small droplets separated from the flue gas gradually condense into larger droplets, and then slide down along the lower part of the demister blade until the slurry pool. The scrubbed and purified flue gas flows out of the absorption tower, and is eventually heated through the flue gas heat exchanger and discharged into the chimney through the clean flue.
