烟气急冷喷雾解决方案

在危废焚烧系统中，倾入的危废通过炉体整体转动达到均匀混合并沿倾斜方向朝出料端移动。炉后配备二次燃烧室，垃圾在回转窑炉内分解气化产生可燃气体，在二次燃烧室内达到完全燃烧。

从余热锅炉出来的100°- 800°高温烟气在急冷塔中降至200°以下或更低。急冷塔冷却水通过雾化喷枪后，雾化成细小的颗粒与高温烟气充分接触换热，并在短时间内蒸发迅速带走热量，使烟气温度急速下降，防止二噁英在500°—300°的环境重新生成。

急冷塔采用迈德乐前端雾化AirMin喷枪可以更好的提高烟气冷却效率减少消耗，AirMin喷枪的三级雾化原理使其做到超细雾化,能充分与高温烟气充分接触换热,并在短时间内蒸发迅速带走热量,使烟气温度急速下降从而抑止二噁英的产生。

迈德乐前端雾化AirMin喷枪型号多样，可根据流量范围0.2-5.0T/h进行选择，喷雾粒径可达30-200μm，喷枪材质可根据具体情况进行选择：碳化钨TC，哈氏合金，40cr.

Gas cooling spraying solution

In the hazardous waste incineration system, the dumped hazardous waste is mixed uniformly by the overall rotation of the furnace and moves in an inclined direction towards the discharge end. The furnace is equipped with a secondary combustion chamber, where the waste is decomposed and gasified in the rotary kiln to produce combustible gases, which are completely burned in the secondary combustion chamber.

The 100°- 800° high temperature flue gas from the waste heat boiler is reduced to less than 200° or lower in the rapid cooling tower. After passing through the atomizing lance, the cooling water is atomized into fine particles which are in full contact with the high temperature flue gas for heat exchange and evaporate in a short time to quickly take away the heat, causing the flue gas temperature to drop rapidly and preventing the re-generation of dioxins at 500°-300°.

The three-stage atomization principle of the AirMin lance makes it possible to achieve ultra-fine atomization, which is in full contact with the high temperature flue gas, and evaporates in a short time to quickly take away the heat, causing the flue gas temperature to drop rapidly and thus suppressing the production of dioxins.

The AirMin front-end atomization guns are available in a wide range of models, depending on the flow rate of 0.2-5.0 T/h, with a spray particle size of 30-200 µm and in the following materials: tungsten carbide TC, Hastelloy, 40cr.
